Drugs that stimulate contraction of the myometrium. They are used to induce LABOR, OBSTETRIC at term, to prevent or control postpartum or postabortion hemorrhage, and to assess fetal status in high risk pregnancies. They may also be used alone or with other drugs to induce abortions (ABORTIFACIENTS). Oxytocics used clinically include the neurohypophyseal hormone OXYTOCIN and certain prostaglandins and ergot alkaloids. (From AMA Drug Evaluations, 1994, p1157)
Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.
Carrier proteins for OXYTOCIN and VASOPRESSIN. They are polypeptides of about 10-kDa, synthesized in the HYPOTHALAMUS. Neurophysin I is associated with oxytocin and neurophysin II is associated with vasopressin in their respective precursors and during transportation down the axons to the neurohypophysis (PITUITARY GLAND, POSTERIOR).
Pituitary Gland, Posterior
Neural tissue of the pituitary gland, also known as the neurohypophysis. It consists of the distal AXONS of neurons that produce VASOPRESSIN and OXYTOCIN in the SUPRAOPTIC NUCLEUS and the PARAVENTRICULAR NUCLEUS. These axons travel down through the MEDIAN EMINENCE, the hypothalamic infundibulum of the PITUITARY STALK, to the posterior lobe of the pituitary gland.
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
Drugs that prevent preterm labor and immature birth by suppressing uterine contractions (TOCOLYSIS). Agents used to delay premature uterine activity include magnesium sulfate, beta-mimetics, oxytocin antagonists, calcium channel inhibitors, and adrenergic beta-receptor agonists. The use of intravenous alcohol as a tocolytic is now obsolete.
Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).
(9 alpha,11 alpha,13E,15S)-9,11,15-Trihydroxyprost-13-en-1-oic acid (PGF(1 alpha)); (5Z,9 alpha,11,alpha,13E,15S)-9,11,15-trihydroxyprosta-5,13-dien-1-oic acid (PGF(2 alpha)); (5Z,9 alpha,11 alpha,13E,15S,17Z)-9,11,15-trihydroxyprosta-5,13,17-trien-1-oic acid (PGF(3 alpha)). A family of prostaglandins that includes three of the six naturally occurring prostaglandins. All naturally occurring PGF have an alpha configuration at the 9-carbon position. They stimulate uterine and bronchial smooth muscle and are often used as oxytocics.
Labor Stage, Third
The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.
Chemical substances having a specific regulatory effect on the activity of a certain organ or organs. The term was originally applied to substances secreted by various ENDOCRINE GLANDS and transported in the bloodstream to the target organs. It is sometimes extended to include those substances that are not produced by the endocrine glands but that have similar effects.

Vasopressin stimulation of acetate incorporation into lipids in a dimethylbenz(a)anthracene-induced rat mammary tumor cell line. (1/1958)In a preliminary report we described the effects of rat prolactin on the incorporation of [14C]acetate into lipids by a cell line from a dimethylbenz(a)anthracene-induced rat mammary tumor. The characteristics of the response to prolactin were very similar to those described for the normal rat mammary gland; namely, insulin was required for full expression of the response, maximal activity was not seen until 36 hr after the addition of the hormones, and growth hormone was able to elicit the same response. However, we were unable to detect binding of 125I-labeled prolactin to these cells, and furthermore, other more purified prolactin preparations were inactive. Upon further investigation we discovered that the activity resided in a low-molecular-weight fraction of the rat prolactin B-1 preparation and was probably either vasopressin or oxytocin or both. These data suggest the possibility that vasopressin may play a role in rodent mammary tumorigenesis. (+info)
Central peptidergic neurons are hyperactive during collateral sprouting and inhibition of activity suppresses sprouting. (2/1958)Little is known regarding the effect of chronic changes in neuronal activity on the extent of collateral sprouting by identified CNS neurons. We have investigated the relationship between activity and sprouting in oxytocin (OT) and vasopressin (VP) neurons of the hypothalamic magnocellular neurosecretory system (MNS). Uninjured MNS neurons undergo a robust collateral-sprouting response that restores the axon population of the neural lobe (NL) after a lesion of the contralateral MNS (). Simultaneously, lesioned rats develop chronic urinary hyperosmolality indicative of heightened neurosecretory activity. We therefore tested the hypothesis that sprouting MNS neurons are hyperactive by measuring changes in cell and nuclear diameters, OT and VP mRNA pools, and axonal cytochrome oxidase activity (COX). Each of these measures was significantly elevated during the period of most rapid axonal growth between 1 and 4 weeks after the lesion, confirming that both OT and VP neurons are hyperactive while undergoing collateral sprouting. In a second study the hypothesis that chronic inhibition of neuronal activity would interfere with the sprouting response was tested. Chronic hyponatremia (CH) was induced 3 d before the hypothalamic lesion and sustained for 4 weeks to suppress neurosecretory activity. CH abolished the lesion-induced increases in OT and VP mRNA pools and virtually eliminated measurable COX activity in MNS terminals. Counts of the total number of axon profiles in the NL revealed that CH also prevented axonal sprouting from occurring. These results are consistent with the hypothesis that increased neuronal activity is required for denervation-induced collateral sprouting to occur in the MNS. (+info)
Production of prostaglandin f2alpha and its metabolite by endometrium and yolk sac placenta in late gestation in the tammar wallaby, Macropus Eugenii. (3/1958)In this study, we investigated production of prostaglandin (PG) F2alpha and its metabolite, PGFM, by uterine tissues from tammar wallabies in late pregnancy. Endometrial explants were prepared from gravid and nongravid uteri of tammars between Day 18 of gestation (primitive streak) and Day 26.5 (term) and were incubated in Ham's F-10 medium supplemented with glutamine and antibiotics for 20 h. PGF2alpha and PGFM in the medium were assayed by specific, validated RIAs. Control tissues (leg muscle) did not produce detectable amounts of either PG. Both gravid and nongravid endometria secreted PGF2alpha, and production increased significantly in both gravid and nongravid uteri towards term. PGFM was produced in small amounts by both gravid and nongravid uteri, and the rate of production did not increase. Neither oxytocin nor dexamethasone stimulated PG production in vitro in any tissue at any stage. Thus, the surge in peripheral plasma PGFM levels seen at parturition may arise from increased uterine PG production, but further study is needed to define what triggers this release. (+info)
Down-regulation of oxytocin-induced cyclooxygenase-2 and prostaglandin F synthase expression by interferon-tau in bovine endometrial cells. (4/1958)Oxytocin (OT) is responsible for the episodic release of luteolytic prostaglandin (PG) F2alpha from the uterus in ruminants. The attenuation of OT-stimulated uterine PGF2alpha secretion by interferon-tau (IFN-tau) is essential for prevention of luteolysis during pregnancy in cows. To better understand the mechanisms involved, the effect of recombinant bovine IFN-tau (rbIFN-tau) on OT-induced PG production and cyclooxygenase-2 (COX-2) and PGF synthase (PGFS) expression in cultured endometrial epithelial cells was investigated. Cells were obtained from cows at Days 1-3 of the estrous cycle and cultured to confluence in RPMI medium supplemented with 5% steroid-free fetal calf serum. The cells were then incubated in the presence or absence of either 100 ng/ml OT or OT+100 ng/ml rbIFN-tau for 3, 6, 12, and 24 h. OT significantly increased PGF2alpha and PGE2 secretion at all time points (p < 0.01), while rbIFN-tau inhibited the OT-induced PG production and reduced OT receptor binding in a time-dependent manner. OT increased the steady-state level of COX-2 mRNA, measured by Northern blot, which was maximal at 3 h (9-fold increase) and then decreased with time (p < 0.01). OT also caused an increase in COX-2 protein, which peaked at 12 h (11-fold increase), as measured by Western blot. Addition of rbIFN-tau suppressed the induction of COX-2 mRNA (89%, p < 0.01) and COX-2 protein (50%, p < 0.01) by OT. OT also increased PGFS mRNA, and this stimulation was attenuated by rbIFN-tau (p < 0.01). To ensure that the decrease in COX-2 was not solely due to down-regulation of the OT receptor, cells were stimulated with a phorbol ester (phorbol 12-myristate 13-acetate; PMA) in the presence and absence of rbIFN-tau. The results showed that rbIFN-tau also decreased PMA-stimulated PG production and COX-2 protein. It can be concluded that rbIFN-tau inhibition of OT-stimulated PG production is due to down-regulation of OT receptor, COX-2, and PGFS. (+info)
Oxytocin and vasopressin receptors in human and uterine myomas during menstrual cycle and early pregnancy. (5/1958)The purpose of this study was to determine the specificity and concentration of oxytocin (OT) and arginine vasopressin (AVP) binding sites in non-pregnant (NP) human and rhesus monkey endometrium, myometrium and fibromyomas, and to determine the cellular localization of OT receptor (OTR). Besides [3H]AVP, [125I]LVA, a specific VP1 receptor subtype antagonist, was used to determine vasopressin receptor (VPR) concentrations. Samples were obtained from 42 pre-menopausal and three pregnant women (5, 13 and 35 weeks gestation), and several NP and pregnant monkeys. Specificity of binding was assessed in competition experiments with unlabelled agonists and antagonists of known pharmacological potency. Cellular localization of OTR was determined by immunohistochemistry. In NP human uterine tissues, [3H]AVP was bound with higher affinity and greater binding capacity than [3H]OT, whereas in pregnant women and in NP and pregnant rhesus monkeys, uterine OT binding capacity was greater. OT and AVP binding sites discriminated very poorly between OT and AVP; [125I]LVA binding sites were more selective than [3H]AVP. Their ligand specificity and binding kinetics indicated the presence of two distinct populations of binding sites for OT and AVP in primate uterus. Endometrium of NP women and monkeys had low OTR and VPR concentrations. Myometrial and endometrial OTR and VPR were down-regulated in midcycle and in early human pregnancy, they were up-regulated in the secretory phase and second half of pregnancy. Immunoreactive OTR in NP uterus was localized in patches of myometrial muscle cells and small numbers of endometrial epithelial cells. (+info)
Desensitization of oxytocin receptors in human myometrium. (6/1958)In the present study, we investigated the possible mechanisms by which oxytocin might regulate oxytocin receptor (OTR) density. Exposure of cultured myometrial cells to oxytocin for a prolonged period caused desensitization: the steady-state level of oxytocin binding was 210 x 10(3) binding sites/cell, but this was time-dependently reduced to 20.1 x 10(3) sites/cell by exposing the cells to oxytocin for up to 20 h. In contrast, Western blotting data showed that the total amount of OTR protein was not affected by oxytocin treatment for up to 24 h. Flow cytometry experiments demonstrated that OTRs were not internalized during this treatment. However, RNase protection assays and Northern analysis showed that in cultured myometrial cells OTR mRNA was reduced by oxytocin treatment to reach a new low steady-state concentration. Analysis of this mRNA in myometrial biopsies from 17 patients undergoing emergency Caesarean section showed how it decreased with advancing labour. Samples obtained after 12 h of labour contained approximately 50 times less OTR mRNA than samples obtained from patients in labour for less than 12 h. We speculate that this decrease in OTR mRNA represents in-vivo OTR desensitization. (+info)
Uterine peristalsis during the follicular phase of the menstrual cycle: effects of oestrogen, antioestrogen and oxytocin. (7/1958)Uterine peristalsis, directing sustained and rapid sperm transport from the external cervical os or the cervical crypts to the isthmic part of the tube ipsilateral to the dominant follicle, changes in direction and frequency during the menstrual cycle, with lowest activity during menstruation and highest activity at mid cycle. It was therefore suggested that uterine peristalsis is under the control of the dominant follicle with the additional involvement of oxytocin. To test this hypothesis, vaginal sonography of uterine peristalsis was performed in the early, mid and late proliferative phases, respectively, of cycles of women treated with oestradiol valerate and with human menopausal gonadotrophin following pituitary downregulation, with clomiphene citrate and with intravenous oxytocin, respectively. Administration of oestradiol valerate resulted in oestradiol serum concentrations comparable with the normal cycle with a simulation of the normal frequency of peristaltic contractions. Elevated oestradiol concentrations and bolus injections of oxytocin resulted in a significant increase in the frequency of peristaltic contractions in the early and mid follicular phases, respectively. Chlomiphene tended, though insignificantly so, to suppress the frequency of peristaltic waves in the presence of elevated oestradiol concentrations. In the late follicular phase of the cycle extremely elevated oestradiol concentrations as well as the injection of oxytocin resulted only in an insignificant further increase of peristaltic frequency. In the normal cycles, as well as during extremely elevated oestradiol concentrations and following oxytocin administration, the peristaltic contractions were always confined to the subendometrial layer of the muscular wall. The results and the review of literature indicate that uterine peristalsis during the follicular phase of the menstrual cycle is controlled by oestradiol released from the dominant follicle with the probable involvement of oxytocin, which is presumably stimulated together with its receptor within the endometrial-subendometrial unit and therefore acting in an autocrine/paracrine fashion. Since unphysiological stimulation with oestradiol and oxytocin did not significantly increase the frequency of uterine peristalsis in the late follicular phase of the cycle it is assumed that normal preovulatory frequency of uterine peristalsis is at a level which cannot be significantly surpassed due to phenomena of refractoriness of the system.

Sperm transport in the human female genital tract and its modulation by oxytocin as assessed by hysterosalpingoscintigraphy, hysterotonography, electrohysterography and Doppler sonography. (8/1958)The transport function of the uterus and oviducts and its modulation by oxytocin has been examined using hysterosalpingoscintigraphy, recording of intrauterine pressure, electrohysterography and Doppler sonography of the Fallopian tubes. After application to the posterior vaginal fornix, a rapid (within minutes) uptake of the labelled particles into the uterus was observed during the follicular and during the luteal phase of the cycle in all patients. Transport into the oviducts, however, could only be demonstrated during the follicular phase. Transport was directed predominantly into the tube ipsilateral to the ovary bearing the dominant follicle; the contralateral oviduct appeared to be functionally closed. The proportion of patients exhibiting ipsilateral transport did increase concomitant with the increase of the diameter of the dominant follicle. That ipsilateral transport has biological significance is suggested by the observation that the pregnancy rate following spontaneous intercourse or insemination was significantly higher in those women in whom ipsilateral transport could be demonstrated than in those who failed to exhibit lateralization. Oxytocin administration was followed by a dramatic increase in the amount of material transported to the ipsilateral tube, as demonstrated by radionuclide imaging and by Doppler sonography following instillation of ultrasound contrast medium. Continuous recording of intrauterine pressure before and after oxytocin administration did show an increase in basal tonus and amplitude of contractions and a reversal of the pressure gradient from a fundo-cervical to a cervico-fundal direction. These actions of oxytocin were accompanied by an increase in amplitude of potentials recorded by electrohysterography. These data support the view that uterus and Fallopian tubes represent a functional unit that is acting as a peristaltic pump and that the increasing activity of this pump during the follicular phase of the menstrual cycle is reflected by an increased transport into the oviduct ipsilateral to the ovary bearing the dominant follicle. In addition, they strongly suggest a critical role of oxytocin in this process. Failure of this mechanism appears to be a cause of subfertility or infertility, as indicated by the low pregnancy rate following intrauterine insemination or normal intercourse in the presence of patent Fallopian tubes. It may be regarded as a new nosological entity for which we propose the term tubal transport disorder (TTD). Since pregnancy rate of such patients is normal when treated with in-vitro fertilization (IVF), hysterosalpingoscintigraphy seems to be useful for the choice of treatment modalities in patients with patent Fallopian tubes suffering from infertility.

Oxytocin for Depression - Oxytocin Accelerator
Oxytocin and Personality. Evidence suggests that the neuropeptide oxytocin plays a role in social affiliation. This behavior may be related more to personality dimensions than specific psychiatric diagnoses. This study investigated the relationship between plasma oxytocin levels and personality dimensions using the Temperament and Character Inventory (TCI) in 60 outpatients with major depression. The strongest correlation was between plasma oxytocin levels and the temperament dimension of Reward Dependence (0.425 Pearson correlation). This suggested that 17% of the variance in plasma oxytocin levels was explained by the Reward Dependence scores. There was a significant positive correlation between plasma oxytocin levels and the Reward Dependence personality dimension.. Nicknamed the cuddle chemical because it renders a warm and fuzzy feeling inside, oxytocin, (a naturally produced hormone) has been shown via brain scan to lower activity in the amygdala - a region which is overactive in social ...
Oxytocin | San Diego Sexual Medicine
Oxytocin is both a hormone secreted by the pituitary gland and also a brain neurotransmitter. The actions of oxytocin are mediated by specific, high affinity oxytocin receptors. Oxytocin has a well-recognized role in breastfeeding, and uterine contraction.. In sexual medicine, oxytocin has a role in orgasm. Several studies have found increases in plasma oxytocin at orgasm. Plasma oxytocin levels are notably increased around the time of orgasm and are still higher than baseline when measured 5 minutes after self-arousal. It is possible that oxytocins effects on muscle contractibility may facilitate male sperm and female egg transport. Oxytocin levels in women before and after sexual stimulation suggests that oxytocin serves an important role in sexual arousal. One study showed that genital tract stimulation resulted in increased oxytocin immediately after orgasm. Another study reported increases of oxytocin during sexual arousal in response to nipple/areola, genital, and/or genital tract ...
Sex-specific effects of intranasal oxytocin on thermal pain perception: A randomised, double-blind, placebo-controlled cross...
Chronic neck and shoulder pain (CNSP) is a common musculoskeletal disorder in adults, which is linked to hypersensitivity to noxious stimuli. The hormone oxytocin has been implicated as a potential therapeutic for the management of chronic pain disorders, and has been suggested to have sex-specific effects on the salience of threatening stimuli. This study investigated the influence of intranasal oxytocin on the perception of noxious thermal stimuli. Participants were 24 individuals with CNSP lasting |12months (eight women), and 24 age- and sex-matched healthy, pain-free controls. In a randomised double-blind, placebo-controlled, cross-over study, participants attended two sessions, self-administering intranasal oxytocin (24 IU) in one session, and placebo in another. Participants rated intensity and unpleasantness of thermal heat stimuli at three body sites: the cervical spine, deltoid, and tibialis anterior, on 11-point numerical rating scales. Compared with placebo, intranasal oxytocin increased the
Inhibitory effect of barusiban and atosiban on oxytocin-induced contractions of myometrium from preterm and term pregnant women...
BACKGROUND A synthetic oxytocin analogue, barusiban, was shown to potently inhibit oxytocin-induced activity of myometrium from term pregnant women. The responsiveness to vasopressin was not influenced by the compound. OBJECTIVE To test the effect of barusiban and a reference compound, atosiban, on oxytocin-induced activity of myometrium from women at preterm pregnancy in comparison to myometrium from women at term. METHODS Fifteen preterm (30-36 gestational weeks) and 12 term pregnant women (38-41 weeks) who underwent cesarean delivery donated myometrial tissue for the study. Concentration-response curves following oxytocin administration to isolated myometrial strips were recorded in control experiments, in the presence of barusiban at concentrations of 2.5, 25, and 250 nM, and of atosiban at concentrations of 25, 250, and 750 nM. Effective concentration 50% (EC50) and pA2 values were calculated. RESULTS Both antagonists in higher concentrations increased the EC50 values to oxytocin. The median
Oxytocin as a neurotransmitter: beyond the peripheral scope] | eLitMed
[Besides its effect on the uterus and breasts, oxytocin also regulates affiliative behaviour. The so-called central oxytocin effect influences pair bonding, maternal care and attachment through the regulatory functions of oxytocin that acts as a neurotransmitter within the brain. The central oxytocin effect increases trust and social support, decreases fear and anxiety, and promotes wound healing. These effects form the basis of the stress-triggered, oxytocin-based calm and connection reaction. Some methods that are widely used in modern obstretric practice - such as the use of synthetic oxytocin for inducing or speeding up labour or epidural anaesthesia - hinder the psycho-emotive effects that are based on natural oxytocin. Epigenetic studies performed in animals indicate that the oxytocin effect experienced at birth can be transgenerational.]

Low Oxytocin Linked to Postpartum Depression - Oxytocin Accelerator
A recent study demonstrated that pregnant women with low oxytocin have a higher risk of postpartum depression. This should come as a surprise to no one. Studies have already demonstrated that low oxytocin release inhibits happy parenting. High oxytocin the opposite. Young non depressed fathers given oxytocin spray seem happier and are more likely to encourage their children to explore during playtime and are less likely to be hostile, compared to fathers given an oxytocin placebo. Mothers with higher oxytocin levels are less likely to be depressed adn more likely to coo to their babies in a playful voice, a speech scientists call motherese. High oxytocin mothers smile more at their babies and are more flexible to changes in its moods. The additional touching, looking into the eyes, lullabys releases even more oxytocin in both mother, father and child. Parents that look into each others eyes release more oxytocin. A test for parents with low oxytocin may one day help to identify mothers and ...
Plasma vasopressin, oxytocin, estradiol, and progesterone related to water and sodium excretion in normal pregnancy and...
The aim of this thesis was to determine any association between plasma oxytocin and vasopressin concentrations and renal water and sodium excretion during normal pregnancy. In addition to investigate changes in concentrations of estradiol, progesterone, oxytocin, cortisol, and glucose in the blood before and in the nearest hours after delivery and if treatment with oxytocin affected these concentrations and the fluid balance during the different stages of labour.. Oxytocin, vasopressin, estradiol, progesterone, and cortisol were analysed in blood plasma or serum by radioimmunoassay or ELISA: serum glucose, and osmolality, and sodium in plasma and urine were analysed by standard laboratory techniques.. Fifty-seven women were studied during pregnancy and fifty-one during parturition and post partum. The low plasma vasopressin and increasing plasma oxytocin concentrations with unchanged water and sodium excretion indicate that oxytocin assists vasopressin in concentrating urine during ...
Extrahypothalamic oxytocin neurons drive stress-induced social vigilance and avoidance | PNAS
Oxytocin increases the salience of both positive and negative social contexts and it is thought that these diverse actions on behavior are mediated in part through circuit-specific action. This hypothesis is based primarily on manipulations of oxytocin receptor function, leaving open the question of whether different populations of oxytocin neurons mediate different effects on behavior. Here we inhibited oxytocin synthesis in a stress-sensitive population of oxytocin neurons specifically within the medioventral bed nucleus of the stria terminalis (BNSTmv). Oxytocin knockdown prevented social stress-induced increases in social vigilance and decreases in social approach. Viral tracing of BNSTmv oxytocin neurons revealed fibers in regions controlling defensive behaviors, including lateral hypothalamus, anterior hypothalamus, and anteromedial BNST (BNSTam). Oxytocin infusion into BNSTam in stress naïve mice increased social vigilance and reduced social approach. These results show that a population ...
Oxytocin administration suppresses hypothalamic activation in response to visual food cues
The aim of this study was to use functional neuroimaging to investigate whether oxytocin modulates the neural response to visual food cues in brain regions involved in the control of food intake. Twenty-four normal weight volunteers received intranasal oxytocin (24 IU) or placebo in a double-blind, randomized crossover study. Measurements were made forty-five minutes after dosing. On two occasions, functional MRI (fMRI) scans were performed in the fasted state; the blood oxygen level-dependent (BOLD) response to images of high-calorie foods versus low-calorie foods was measured. Given its critical role in eating behaviour, the primary region of interest was the hypothalamus. Secondary analyses examined the parabrachial nuclei and other brain regions involved in food intake and food reward. Intranasal oxytocin administration suppressed hypothalamic activation to images of high-calorie compared to low-calorie food (P = 0.0125). There was also a trend towards suppression of activation in the ...
Safety Study of Intranasal Oxytocin in Frontotemporal Dementia - Full Text View - ClinicalTrials.gov
Oxytocin is a hormone produced by the brain that appears to have important roles in social cognition and emotion in humans. In a pilot study, the effects of a single dose of oxytocin on measures of emotion recognition and behaviour in patients with Frontotemporal Dementia were investigated. The results from the pilot study suggested that oxytocin may be associated with a modest improvement in neuropsychiatric behaviours seen in patients with Frontotemporal Dementia. To further examine the safety and tolerability of oxytocin in this disorder, the present study will examine the safety and tolerability of three different doses of intranasal oxytocin administered to patients with Frontotemporal Dementia twice daily for 1 week ...
INACTIVATION OF OXYTOCIN AND SYNTHETIC OXYTOCIN ANALOGUES BY HEN TISSUES in: Journal of Endocrinology Volume 63 Issue 2 (1974)
The oxytocin-inactivating activity (OIA) of liver, kidney, uterus, pancreas, spleen and duodenum homogenates of hens was studied. The first-order constant of oxytocin inactivation was higher in the liver and pancreas than in the uterus and kidney or in the duodenum and spleen. Using synthetic analogues of oxytocin (deamino-oxytocin, deamino-carba1-oxytocin and carba1-oxytocin the mechanism of enzymic inactivation of oxytocin by hen tissue was investigated.. Enzymic hydrolysis by the CH2-terminal cleavage was most marked in duodenum (about 86% OIA) and kidney (54·8% OIA). Reduction of the disulphide bridge was most marked in the uterus (about 80% OIA) and pancreas (about 73% OIA). Splitting by non-specific aminopeptidases after reduction of the disulphide bridge occurred mainly in the liver (72% OIA) and in the spleen (44% OIA). ...

A study to determine minimum effective dose of oxytocin infusion during caesarean delivery in parturients at high risk of...
Abstract: Background: Oxytocin, a commonly used drug to prevent uterine atony after caesarean section, should be administered as dilute rapid infusion rather than as a bolus. This study was conducted to calculate ED90 of oxytocin infusion during caesarean delivery in parturients at high risk of postpartum haemorrhage (PPH). Materials and Methods: One hundred and twenty parturients having one or more risk factors for PPH received a blinded infusion of oxytocin following emergency caesarean delivery. The initial dose of oxytocin infusion was started as 0.4 IU min−1. The dose of oxytocin infusion for the next parturient was based on the response of preceding patient in increments or decrements of 0.1 IU min−1 as per a biased-coin design up-down sequential method (UDM). Measurements of non-invasive blood pressure and heart rate were taken at 2 min intervals from the time of oxytocin infusion. Intraoperative blood loss was noted. Side effects such as tachycardia, hypotension, nausea, vomiting, ...
A comparison of the effect of nipple stimulation and oxytocin infusion on the duration of phases of labor | Journal of...
Background: Oxytocin infusion is used for induction or augmentation of labor to prevent prolonged labor. A cheap and nonaggressive alternative which is effectively used for contraction stress test is nipple stimulation. However research regarding its efficacy and safety is still limited. This study aims to compare the effectiveness of nipple stimulation and oxytocin infusion on the duration of phases of labor.Methods: This randomized clinical trial included 132 low-risk pregnant women admitted to Asali hospital in 2006 -2007. Those having poor contractions in active phase of labor were randomly assigned into two groups of nipple stimulation and oxytocin infusion. Women in the nipple stimulation group had their nipples messaged by hands moving in circle and using lubricant gel. The oxytocin infusion was started at 0.25 mIU/min for the oxytocin infusion group. Data collection was carried out through observation, examination and interviews. Data were analyzed using statistical tests, repeated measure test,
Oxytocin Add-on Study for Stable Anxiety Patients - Full Text View - ClinicalTrials.gov
Anxious patients treated with even the best currently available anti-anxiety drugs continue to experience significant symptoms.. A variety of basic science, animal studies, and human studies support the idea that the neuropeptide oxytocin may be effective against anxiety in humans. For example, plasma oxytocin levels may function as an index of central serotonin (5-HT) function in human subjects, and serotonin is well-known to be involved in clinical anxiety disorders. Since oxytocin is released directly from limbic-hypothalamic cells, this response presumably represents a direct central assessment of 5-HT response in limbic-hypothalamus (Lee 2003). In animal models, Ring 2006 examined the effects of oxytocin on both behavioral and autonomic parameters of the anxiety response in male mice using three pharmacologically validated preclinical models of anxiety: the four-plate test (FPT), elevated zero maze (EZM), and stress-induced hyperthermia (SIH). The results from this study provide specific ...
Oxytocin, Adrenocorticotropic Hormone and Cortisol: Roles of Oxytocin by Amira Athanasios
Oxytocin is a neurohormone that has been correlated with lactation, uterine-contractions, postpartum behavior, pro-social behavior, trust, empathy, and decreased anxiety. In addition, oxytocin is believed to underscore the tend-and-befriend response to stress. In this study, adrenocorticotropic hormone (ACTH), cortisol and oxytocin levels were measured in response to a social stressor in human participants. Oxytocin was initially seen to increase with ACTH and cortisol in response to a social stressor. As levels of oxytocin increase, levels of ACTH and cortisol were shown to decrease or plateau. I conclude that oxytocin is released in response to a perceived stressor and display inhibitory effects over ACTH and cortisol.
Release of oxytocin during suckling and parturition in the rat in: Journal of Endocrinology Volume 105 Issue 3 (1985)
A highly sensitive and specific radioimmunoassay (RIA) for oxytocin was developed and used to measure oxytocin concentrations during both suckling and parturition in individual rats. In urethane-anaesthetized rats, the suckling stimuli, provided by ten pups, induced intermittent increases in intramammary pressure of about 10 mmHg. This was associated with a significant (P , 0·01) increase in serum oxytocin levels from 19·5 ± 4·5 (s.e.m., n = 9) to 49·1 ± 7·4 pmol/l (n = 9) in the samples taken within 30 s from the time of the peak in the pressure. These rises in serum oxytocin returned rapidly to the basal levels as expected from the short half-life (1·46 min) of oxytocin in general circulation.. On day 22 or 23 of gestation, serum oxytocin levels remained stable until 0-0·5 h before the first fetus was expelled. They then increased significantly (P , 0·01) from 27·6± 4·6 pmol/l (n = 19) in samples taken 0-0·5 h before to 45·1 ± 5·6 pmol/l in samples taken after the expulsion of ...
Maybe Im jumping too quickly to put two and two together but juxtaposing the description of the effect of Smiths Nambian root with the actions of oxytocin, I cant but wonder if there is some connection. There are numerous examples of other plants which contain hormones. Could this root contain oxytocin or could something in it stimulate oxytocin release in people? Food for thought, eh?. Here is concise but partial summary of oxytocins actions in the brain from Wikipedia:. 1. Sexual arousal. Oxytocin injected into the cerebrospinal fluid causes spontaneous erections in rats, reflecting actions in the hypothalamus and spinal cord. 2. Bonding. In the Prairie Vole, oxytocin released into the brain of the female during sexual activity is important for forming a monogamous pair bond with her sexual partner. Vasopressin appears to have a similar effect in males. In people, plasma concentrations of oxytocin have been reported to be higher amongst people who claim to be falling in love. Oxytocin has ...
Frontiers | Cyclic ADP-Ribose and Heat Regulate Oxytocin Release via CD38 and TRPM2 in the Hypothalamus during Social or...
Hypothalamic oxytocin (OT) is released into the brain by cyclic ADP-ribose (cADPR) with or without depolarizing stimulation. Previously, we showed that the intracellular free calcium concentration ([Ca2+]i) that seems to trigger OT release can be elevated by -NAD+, cADPR, and ADP in mouse oxytocinergic neurons. As these -NAD+ metabolites activate warm-sensitive TRPM2 cation channels, when the incubation temperature is increased, the [Ca2+]i in hypothalamic neurons is elevated. However, it has not been determined whether OT release is facilitated by heat in vitro or hyperthermia in vivo in combination with cADPR. Furthermore, it has not been examined whether CD38 and TRPM2 exert their functions on OT release during stress or stress-induced hyperthermia in relation to the anxiolytic roles and social behaviors of OT under stress conditions. Here, we report that OT release from the isolated hypothalami of male mice in culture was enhanced by extracellular application of cADPR or increasing the
Oxytocin Hormone Promotes Social Behavior in Infant Rhesus Monkeys | Office of News & Media Relations | UMass Amherst
AMHERST, Mass. - The hormone oxytocin appears to increase social behaviors in newborn rhesus monkeys, say researchers at the National Institutes of Health, the University of Parma, Italy, and the University of Massachusetts Amherst. Findings suggest that oxytocin is a promising candidate for new treatments for developmental disorders affecting social skills and bonding.. Oxytocin, a hormone produced by the pituitary gland, is involved in labor, birth and breast milk production. Studies have also shown that oxytocin plays a role in parental bonding, mating and social interactions. Because of this, many researchers have suggested that oxytocin might be useful in treating conditions affecting social behavior such as autism spectrum disorders.. Earlier research in adults has shown that oxytocin increases certain social behaviors, says behavioral endocrinologist Jerrold Meyer of UMass Amherst, but the current study is the first to show that it may have the same effect in primate infants, including ...
Oxytocin regulates Ca2+ level in myometrium by influencing phosphoinositide metabolism. - Semantic Scholar
The effect of oxytocin on phosphoinositide metabolism as well as on membrane protein phosphorylation in myometrial tissue was studied. Oxytocin enhanced the 32P incorporation into phospholipids in myometrial tissue. The effect of oxytocin on phosphoinositide metabolism was also detected in plasma membrane of 20 days pregnant rats. Phosphorylated membrane lipids have been analysed and phosphatidylinositol 4, 5-bisphosphate proved to be the main reaction product. Oxytocin enhanced the 32P incorporation into phospholipids measured in the first 30 sec then the labeling decreased more rapidly then in case of the control. The effect of oxytocin proved to be concentration dependent. The protein phosphorylation was also influenced by oxytocin. However the amount of alkylphosphate formed depended on the presence or absence of Ca2+, Ca2+-calmodulin and cyclic AMP, oxytocin influenced the protein phosphorylation in the presence of Ca2+-calmodulin only.

Frontiers | Vasopressin and Oxytocin Reduce Food Sharing Behavior in Male, but Not Female Marmosets in Family Groups |...
Oxytocin is critical for lactation and maternal care, but oxytocin and the related nonapeptide vasopressin are important for caregiving behaviors in fathers and alloparents as well. This experiment tested the effects of vasopressin and oxytocin on food sharing in marmoset families. We treated caregivers (parents, siblings) with intranasal vasopressin, oxytocin, or saline, and then paired them with the youngest marmoset in the family. Caregivers were given preferred food, and then observed for food sharing and aggressive behavior with young marmosets. Oxytocin reduced food sharing from male alloparents to youngest siblings, and fathers that received vasopressin refused to share food with their youngest offspring more often than when treated with oxytocin. Vasopressin increased aggressive vocalizations directed toward potential food recipients in all classes of caregivers. These results indicate that vasopressin and oxytocin do not always enhance prosocial behavior: modulation of food sharing depends on
Oxytocin | elephantcare
Elephant specific information, if available, is in blue.. Chemistry - A nonapeptide hypothalamic hormone stored in the posterior pituitary (in mammals), oxytocin occurs as a white powder that is soluble in water. The commercially available preparations are highly purified and have virtually no antidiuretic or vasopressor activity when administered at usual doses. Oxytocin potency is standardized according to its vasopressor activity in chickens and is expressed in USP Posterior Pituitary Units. One unit is equivalent of approximately 2.0 - 2.2 micrograms of pure hormone.. Commercial preparations of oxytocin injection have their pH adjusted with acetic acid to 2.5-4.5 and multi-dose vials generally contain chlorbutanol 0.5% as a preservative.. Storage/Stability/Compatibility - Oxytocin injection should be stored at temperatures of less than 25°C, but should not be frozen. Some manufacturers recommend storing the product under refrigeration (2-8°C), but some products have been demonstrated to be ...

PART 2 - INTERVIEW PAUL ZAK, PHD - WHAT IS OXYTOCIN ? HOW CAN IT IMPROVE QOL AND HEALTHCARE OUTCOMES? - CancerLife
Question: What is oxytocin?. Paul: Oxytocin is a mammalian neurochemical that your brain makes and is released during almost any positive social interaction. It motivates us to engage with other people. When your brain makes oxytocin, you have an increased sense of empathy for about ½ hour and reduced stress. During that time, you are more motivated to connect to people around you . The release of oxytocin also activates a much larger network in the brain, called the HOME Network: Human Oxytocin Mediated Empathy system. Oxytocin facilitates the mid-brain to release a chemical called dopamine that is essentially the reward signal. It makes us feel good. Nature has set up a system that rewards us we connect to others, as we relax and feel good.. The HOME Network directly improves the systems of depression, anxiety, and loneliness. It can also directly impact and potentially slow tumor growth by reducing the production of the stress hormone cortisol. Question: What has your oxytocin research ...
Visualization of oxytocin release that mediates paired pulse facilitat by Ramón A. Piñol, Heather Jameson et al.
© 2014, PLOS ONE. Recent work has shown that oxytocin is involved in more than lactation and uterine contraction. The paraventricular nucleus of the hypothalamus (PVN) contains neuroendocrine neurons that control the release of hormones, including vasopressin and oxytocin. Other populations of PVN neurons do not release hormones, but rather project to and release neurotransmitters onto other neurons in the CNS involved in fluid retention, thermoregulation, sexual behavior and responses to stress. Activation of oxytocin receptors can be cardioprotective and reduces the adverse cardiovascular consequences of anxiety and stress, yet how oxytocin can affect heart rate and cardiac function is unknown. While anatomical work has shown the presence of peptides, including oxytocin, in the projections from the PVN to parasympathetic nuclei, electrophysiological studies to date have only demonstrated release of glutamate and activation of fast ligand gated receptors in these pathways. In this study, using rats,
Serotonin Gives Oxytocin a Helping Hand | Science Translational Medicine
The neuropeptide oxytocin has been implicated in social behavior and is being evaluated as a possible treatment for autism spectrum disorders and schizophrenia, but the neural mechanisms through which oxytocin modulates social behavior remain largely unknown. One possibility is that social interaction recruits the brains reward circuits and that oxytocin plays a role in this process, which ultimately reinforces social behavior. In a recent study, Dolen et al. elucidate key circuits and mechanisms through which oxytocin can modulate social behavior via actions on the nucleus accumbems, a key component of the brains reward circuitry.. Dolen et al. studied social conditioned place preference (social CPP), in which mice prefer to spend time in a chamber that was previously associated with social interaction instead of in a chamber previously associated with social isolation. This task measures the rewarding effects of social interactions. Dolen et al. found that ablating presynaptic oxytocin ...

Crazy Eddies Motie News: Are your oxytocin levels high enough?
The first bit of evidence that points to oxytocin as natures love glue comes from researchers who measured the hormone in couples. Psychology professor Ruth Feldman at Bar-Ilan University in Israel, spent years studying oxytocins role in the mother-child bond and recently decided to dive into the uncharted waters of romantic bonds by comparing oxytocin levels in new lovers and singles. The increase in oxytocin during the period of falling in love was the highest that we ever found, she says of a study she and her colleagues published in Psychoneuroendocrinology. New lovers had double the amount Feldman usually sees in pregnant women ...
Serotonergic involvement in stress-induced vasopressin and oxytocin secretion - Forskning - Region Hovedstaden
OBJECTIVE: To investigate the involvement of serotonin (5-hydroxytryptamine - 5-HT) receptors in mediation of stress-induced arginine vasopressin (AVP) and oxytocin (OT) secretion in male rats.. DESIGN: Experiments on laboratory rats with control groups.. METHODS: Different stress paradigms were applied after pretreatment with intracerebroventricular infusion of saline or different 5-HT antagonists.. RESULTS: Restraint stress (5 min), hypotensive hemorrhage or dehydration for 24 h increased AVP secretion fivefold and OT secretion threefold. Swim stress for 3 min had no effect on AVP secretion, but increased OT secretion threefold. Ether vapor or hypoglycemia had no effect on AVP or OT secretion. The restraint stress-induced AVP response was inhibited by pretreatment with the 5-HT(2A+2C) antagonists ketanserin (KET) and LY-53857 (LY) and the 5-HT(3+4) antagonist ICS-205930 (ICS), whereas the 5-HT(1A) antagonist WAY-100635 (WAY) had no effect. The OT response to restraint stress was inhibited by ...

ScholarWorks @ UVM - UVM Student Research Conference: The Effects of Behavioral Oxytocin Modification on Romantic Attitudes
Human beings make decisions based on implicit and explicit processes. The implicit processes are regulated by hormones; however, the same hormone could affect multiple behaviors. In this study, I will modify oxytocin levels by manipulating feelings of trustworthiness and observe if the changes in oxytocin levels affect a distinct construct controlled by this hormone: evaluative processes of romantic stimuli. I will utilize a neuroeconomic game to manipulate endogenous oxytocin levels and observe whether this manipulation changes peoples attitudes towards romantic pictures and their overall desire for a romantic connection.
The Love Hormone Oxytocin can also give rise to aggressive behavior | Max-Planck-Gesellschaft
Oxytocin, a peptide produced in the brain, may bring hearts together or it can help induce aggression. That conclusion arises from unique research by scientist in which mice living in semi-natural conditions had their oxytocin producing brain cells manipulated in a highly precise manner. The findings could shed new light on efforts to use oxytocin to treat a variety of psychiatric conditions, from social anxiety and autism to schizophrenia.
Sensitive parenting is associated with plasma oxytocin and polymorphisms in the OXTR and CD38 genes | [email protected]
Background: Research in mammals has demonstrated the involvement of oxytocin (OT) in social bond formation; yet, its role in human bonding remains unclear. Plasma OT has been used as a proxy for central activity and studies indicate its association with human affiliative behaviors. Molecular genetic studies also reveal a role for OT neuropathways in shaping the social brain. However, the links between peripheral OT, genetic markers, and their combined contribution to human parenting are unknown. Methods: Participants included 352 individuals: 272 mothers and fathers and their 4- to 6-month-old-infants and 80 nonparents. Plasma OT was assayed from adults who were genotyped for oxytocin receptor (OXTR) and CD38 risk alleles associated with social dysfunctions. CD38 is an ectoenzyme that mediates the release of brain OT. Parent-infant interactions were microcoded for parental touch and gaze synchrony and participants reported on parental care in childhood. Results: OXTR (rs2254298 and rs1042778) ...
Oxytocin - Academic Kids
Oxytocin analogues (pitocin, Syntocinon®) are used to induce labour and support labour in case of non-progression of the parturition. It has largely replaced ergotamine as the principal agent to increase uterine tone in acute postpartum haemorrhage. An oxytocin nose spray may be a useful adjunct to stimulate breastfeeding. Inhibition of oxytocin action is the mode of action of the new tocolytic agent atosiban (Tractocile®), which is registered in many countries to suppress premature labour between 24 and 33 weeks of gestation. It has fewer side-effects than drugs previously used for this purpose (ritodrine, salbutamol and terbutaline). A 2005 study by Fehr et al suggested that nasally administered oxytocin worked to generate trust in humans. They demonstrated that in a risky investment game, experimental subjects given the hormone displayed what the researchers deemed the highest level of trust twice as often as the control group who were given placebos. The same experiment with the subjects ...
Oxytocin regulates the plasma membrane Ca2+ transport in rat myometrium | Biochemical Journal | Portland Press
Development of myometrium in young female rats was stimulated by administration of diethylstilboestrol. Plasma membrane and sarcoplasmic reticulum from rat myometrium were separated by a new and rapid method using a Percoll gradient. Calcium uptake was inhibited in plasma membrane vesicles isolated from oxytocin-treated myometrium, while no consistent effect of oxytocin was found on the Ca2+ uptake in the sarcoplasmic reticulum. Oxytocin regulated the plasma membrane Ca2+ pump by decreasing its apparent affinity for Ca2+ without affecting its maximal velocity. The K1/2 for Ca2+ in the absence of calmodulin was 0.41 +/- 0.04 microM in normal membranes; this was increased to 0.93 +/- 0.12 microM in oxytocin-treated membranes. Calmodulin decreased the K1/2 for Ca2+ to 0.27 +/- 0.027 microM and oxytocin also increased this, to 0.46 +/- 0.061 microM. The effect of oxytocin on the plasma membrane Ca2+ pump was highly dependent on the hormonal status of the animals. When the diethylstilboestrol was ...
Oxytocin | Get Latest Health News, Articles & Research Updates on Oxytocin at TheHealthSite.com
Oxytocin is a hormone primarily known for increasing bonding, social behaviour and closeness between parents, children and couples. Increased oxytocin levels have been found, for example, in partners in functional relationships. In women, it is also produced during the childbirth process and during breastfeeding to increase the mothers bond with the baby.
30: Myth or Real? There is more to a retained placenta in a mare than simply a uterus that cant or wont respond to oxytocin. ...
Answer: Real. Researchers in Poland recently looked into the issue of retained placenta in draft mares, desiring to answer the question of why treatment of a retained placenta with repeated injections of oxytocin so often fails. They put forth the hypothesis that it may be the expression of oxytocin receptors that differs in mares that retain fetal membranes due to secondary uterine atony (lack of physiologic tone, muscle weakness). The objective of this study was to determine whether the expression of oxytocin receptors in equine placental tissue differs in these draft mares that normally pass their fetal membranes vs. those mares that retain them. Placental biopsies were taken from 8 draft mares during foaling. 4 mares passed their placenta shortly after foaling (control group) and 4 mares retained their placenta due to secondary uterine atony. The number of oxytocin receptors was estimated and the presence and location of these receptors determined. Results showed that the oxytocin receptor ...
Oxytocin increases trust in humans - NASA/ADS
Trust pervades human societies. Trust is indispensable in friendship, love, families and organizations, and plays a key role in economic exchange and politics. In the absence of trust among trading partners, market transactions break down. In the absence of trust in a countrys institutions and leaders, political legitimacy breaks down. Much recent evidence indicates that trust contributes to economic, political and social success. Little is known, however, about the biological basis of trust among humans. Here we show that intranasal administration of oxytocin, a neuropeptide that plays a key role in social attachment and affiliation in non-human mammals, causes a substantial increase in trust among humans, thereby greatly increasing the benefits from social interactions. We also show that the effect of oxytocin on trust is not due to a general increase in the readiness to bear risks. On the contrary, oxytocin specifically affects an individuals willingness to accept social risks arising through

Validation of an enzyme-linked immunoassay (ELISA) for plasma oxytocin in a novel mammal species reveals potential errors...
BACKGROUND: The neuropeptide oxytocin is increasing the focus of many studies investigating human and animal social behaviours and diseases. However, interpretation and comparison of results is made difficult by a lack of consistent methodological approaches towards analysing this hormone. NEW METHOD: This study determined the sample collection and analysis protocols that cause the least amounts of protocol dependant variation in plasma oxytocin concentrations detected by ELISA. The effect of vacutainer type, sample extraction prior to analysis and capture and restraint protocol were investigated while validating an assay protocol for two novel species, grey seals (Halichoerus grypus) and harbour seals (Phoca vitulina). RESULTS: Where samples are extracted prior to analysis, vacutainer type (EDTA mean: 8.25±0.56pg/ml, heparin mean: 8.25±0.62pg/ml, p=0.82), time taken to obtain a sample and restraint protocol did not affect the concentration of oxytocin detected. However, concentrations of ...
Intranasal Oxytocin Soon After a Trauma May Prevent Worsening PTSD : Bipolar Network News
Oxytocin, a hormone that promotes emotional bonding, also benefits people having trouble dealing with stress. A new study suggests that giving oxytocin for a week shortly following a traumatic experience reduces the risk that the recipient will develop post-traumatic stress disorder (PTSD).. In the study by researcher Mirjam van Zuiden and colleagues, people who visited an emergency room following some kind of trauma were randomized to receive either a placebo nasal spray or intranasal oxytocin twice daily for 7.5 days beginning within 12 days after the trauma. The dosage was 40 IU twice daily.. For those participants with severe PTSD symptoms at baseline, repeated oxytocin administration prevented worsening PTSD. The research was presented at the 2016 meeting of the Society of Biological Psychiatry.. ...

DailyMed - OXYTOCIN injection
All patients receiving intravenous oxytocin must be under continuous observation by trained personnel with a thorough knowledge of the drug and qualified to identify complications. A physician qualified to manage any complications should be immediately available.. When properly administered, oxytocin should stimulate uterine contractions similar to those seen in normal labor. Overstimulation of the uterus by improper administration can be hazardous to both mother and fetus. Even with proper administration and adequate supervision, hypertonic contractions can occur in patients whose uteri are hypersensitive to oxytocin.. Except in unusual circumstances, oxytocin should not be administered in the following conditions: prematurity, borderline cephalopelvic disproportion, previous major surgery on the cervix or uterus including Caesarean section, overdistention of the uterus, grand multiparity or invasive cervical carcinoma. Because of the variability of the combinations of factors which may be ...
Use of oxytocin during Caesarean section at Princess Marina Hospital, Botswana : an audit of clinical practice
Background: Oxytocin is widely used for the prevention of postpartum haemorrhage. In the setting of Caesarean section (CS), the dosage and mode of administrating oxytocin differs according to different guidelines. Inappropriate oxytocin doses have been identified as contributory to some cases of maternal deaths. The main aim of this study was to audit the current standard of clinical practice with regard to the use of oxytocin during CS at a referral hospital in Botswana. Methods: A clinical audit of pregnant women having CS and given oxytocin at the time of the operation was conducted over a period of three months. Data included indications for CS, oxytocin dose regimen, prescribing clinicians designation, type of anaesthesia for the CS and estimated blood loss. Results: A total of 139 case records were included. The commonest dose was 20 IU infusion (31.7%). The potentially dangerous regimen of 10 IU intravenous bolus of oxytocin was used in 12.9% of CS. Further doses were utilized in 57 ...

Oxytocin prolongs the gastric emptying time in patients with diabetes mellitus and gastroparesis, but does not affect satiety...
Oxytocin is released in response to a fatty meal. Blockage of the oxytocin receptor led to slower gastric emptying whereas stimulation resulted in less satiety in healthy volunteers. Patients with diabetes mellitus and gastroparesis lack oxytocin elevation, and dyspepsia is partly caused by reduced fundus accommodation causing early satiety and related symptoms. The aim of this study was thus to examine the effect of oxytocin on gastric emptying, satiety and volume intake in patients with gastrointestinal pathology. Gastric emptying scintigraphy was performed twice in 12 patients with diabetic gastroparesis, once with oxytocin and once with saline as intravenous infusions. The patients scored their sensation of satiety using a visual analogue scale (VAS). The gastric emptying in patients with gastroparesis was prolonged during oxytocin infusion (p = 0.034) without affecting satiety. A slow satiety drinking test was performed in 14 patients with functional dyspepsia. The patients scored their satiety

Oxytocin Modulation of Zebra Finch Vocal Development
Autism spectrum disorder is associated with deficits in three main behavioral areas: social behaviors, repetitive behaviors, and language abnormalities. Accumulating evidence suggests a potential role for oxytocin signaling in the etiology of autism. Oxytocin signaling is integral to complex social behaviors such as fear, social recognition, and monogamous pair bonding initiation (Wang and Aragona 2004; Kirsch, Esslinger et al. 2005; Choleris, Little et al. 2007). Furthermore, evidence of a causal relationship between altered oxytocin levels and repetitive behaviors exists both humans and animals (Drago, Pederson et al. 1986; Hollander, Novotny et al. 2003). However, limited research exists to document a role for oxytocin and oxytocin related peptides in communication related behavior either in humans or animal models. Oxytocin immunoreactive neurons have been found in brain areas associated with the vocal behaviors of both the mustached bat and the plainfin midshipman fish and increased plasma ...
Mind-Body Interventions Affect Sleep and Oxytocin in Cancer Survivors - Mind & Life Institute
Oxytocin is a hormone produced in an area of the brain known as the hypothalamus, whose release activates a variety of brain regions resulting in many different functions, including birth (labor), breast feeding (lactation), maternal behavior, parental care, social bonding, affiliation (such as couples being together), and well-being. In recent studies in humans, oxytocin has been shown to be associated with increases in prosocial behaviors such as trust, altruism, generosity, cooperation and empathy. These various functions suggest that oxytocin may promote health by reducing stress and increasing calm/relaxed states, resulting in improved quality of life and well-being.. Given oxytocins stress-reducing and calming properties, and its capacity to increase well-being, its action may be relevant to those fighting cancer. We conducted a study to look at the effects of two mind-body therapies on changes in salivary oxytocin levels in a cancer survivor population with self-reported sleep ...

OBJECTIVE: To study the effects of early versus delayed oxytocin augmentation on the obstetrical and neonatal outcome in nulliparous women with spontaneous but prolonged labour. DESIGN: Randomised controlled study. SETTING: Two delivery units in Sweden. POPULATION: Healthy nulliparous women with normal pregnancies, spontaneous onset of active labour, a cervical dilatation of 4-9 cm and no progress in cervical dilatation for 2 hours and for an additional hour if amniotomy was performed due to slow progress. METHODS: Women (n = 630) were randomly allocated either to labour augmentation by oxytocin infusion (early oxytocin group) or to postponement of oxytocin augmentation for another 3 hours (expectant group). MAIN OUTCOME MEASURE: Mode of delivery (spontaneous vaginal or instrumental vaginal delivery or caesarean section) and time from randomisation to delivery. RESULTS: The caesarean section rate was 29 of 314 (9%) in the early oxytocin group and 34 of 316 (11%) in the expectant group (OR 0.8, 95% CI 0
The differential impact of oxytocin receptor (OXTR) genotypes on the risk of autism spectrum disorder (ASD) and resulting...
Background: Autism spectrum disorder (ASD) is multifactorial and is likely the result of complex interactions between multiple environmental and genetic factors. Recently, it has been suggested that each symptom cluster of the disorder, such as poor social communication, may be mediated by different genetic influences. Genes in the oxytocin pathway, which mediates social behaviours in humans, have been studied with single nucleotide polymorphisms (SNPs) in the oxytocin receptor gene (OXTR) being implicated in ASD. This thesis examines the presence of different oxytocin receptor genotypes, and their associations with ASD and resulting social communication deficits. Methods: The relationship between four OXTR variants and ASD was evaluated in 607 ASD simplex (SPX) families. Cases were compared to their unaffected siblings using a conditional logistic approach. Odds ratios and associated 95 percent confidence intervals were obtained. A second sample of 235 individuals with a diagnosis of ASD was ...
Comparison of particle-associated progesterone and oxytocin in the ovine corpus luteum<...
TY - JOUR. T1 - Comparison of particle-associated progesterone and oxytocin in the ovine corpus luteum. AU - Rice, G. E.. AU - Jenkin, G.. AU - Thorburn, G. D.. PY - 1986/1/1. Y1 - 1986/1/1. N2 - The subcellular distribution of progesterone and oxytocin within the ovine corpus luteum was investigated using differential and density gradient centrifugation. Progesterone and oxytocin were associated with particles which sedimented to a density of 1.049-1.054 g/ml and 1.054-1.061 g/ml respectively. Particle-associated progesterone did not, however, display physical or biochemical characteristics consistent with its storage within secretory granules. When particle-associated progesterone was incubated in HEPES buffer at 37°C, 70% of the total progesterone was recovered in the incubation medium. The remaining stable particle-associated progesterone was not affected by treatments which stimulated oxytocin release and which have been shown to cause the release of peptides and biogenic amines from ...
Integral Options Cafe: Ecstasy (MDMA), Empathy, and Oxytocin
MDMA (±3,4-methylenedioxymethamphetamine, ecstasy) is used recreationally, reportedly because it increases feelings of empathy, sociability, and interpersonal closeness. One line of evidence suggests that MDMA produces these effects by releasing oxytocin, a peptide involved in social bonding. In the current study, we investigated the acute effects of MDMA and oxytocin on social and emotional processing in healthy human volunteers. MDMA users (N=65) participated in a 4-session, within-between-subjects study in which they received oral MDMA (0.75, 1.5 mg/kg), intranasal oxytocin (20 or 40 IU), or placebo under double-blind conditions. The primary outcomes included measures of emotion recognition and sociability (desire to be with others). Cardiovascular and subjective effects were also assessed. As expected, MDMA dose-dependently increased heart rate and blood pressure and feelings of euphoria (eg, High and Like Drug). On measures of social function, MDMA impaired recognition of angry and ...

Mechanisms by which hypoxia augments Leydig cell viability and differentiated cell function in vitro
The 1980s heralded the discovery and identification of extra-pituitary sources of the neurohypophysial hormone oxytocin in non-neural tissues of several animal species. The presence, location and biosynthesis of significant amounts of oxytocin in the ovarian corpus luteum was followed by the immunocytochemical demonstration of an oxytocin-like peptide in the testicular interstitial cells. Leydig cells, which comprise up to 80% of the testicular intertubular cell population, are known to synthesize testosterone in situ. Indirect evidence indicated that an oxytocin-like peptide was also present in Leydig cells.. The question arose whether this peptide was synthesized de novo by Leydig cells or was taken up and stored by the cells following biosynthesis at some other intra- and/or extra-gonadal source(s). Since luteinizing hormone (LH) and ascorbate are known to augment the production of oxytocin in ovarian granulosa cells, varying concentrations of these two stimulants were used to monitor the ...
Spinning Babies Blog: May 2007
4): 270-77) The autistic group appeared to have significantly lower blood oxytocin levels than the normal group.... ... Artificial induction of labour creates situations that undoubtedly interfere with the development and the reorganization of the oxytocin system in such a critical period. This fact alone is a reason for further epidemiological studies focusing on labour induction as a possible risk factor. It would be useful to know also how autistic children release oxytocin. Oxytocin is more effective when released rhythmically, in a succession of fast pulsations. Today it is possible to measure the rhythmicity the pulsatility of oxytocin release. In other words, the time has come to study autism as an impaired capacity to love.. Midwifery Todays Editor Jan Triton notes: Oxytocin is a hormone released by the posterior pituitary gland. Its mechanical effects, particularly its stimulating effects on uterine contractions during labour, have been known for a long time. Recently we learned ...
Sexually dimorphic effects of oxytocin receptor gene ( OXTR ) variants on Harm Avoidance | Biology of Sex Differences | Full...
Recent research has suggested that oxytocin receptor gene (OXTR) variants may account for individual differences in social behavior, the effects of stress and parenting styles. Little is known, however, on a putative role of the gene in heritable temperamental traits. We addressed effects of two common OXTR variants, rs237900 and rs237902, on personality dimensions in 99 healthy subjects using the Temperament and Character Inventory. When sex was controlled for and an OXTR genotype*sex interaction term was included in the regression model, 11% of the variance in Harm Avoidance could be explained (uncorrected p ≤ 0.01). Female carriers of the minor alleles scored highest, and a novel A217T mutation emerged in the most harm avoidant male participant. Findings lend support to a modulatory effect of common OXTR variants on Harm Avoidance in healthy caucasian women and invite resequencing of the gene in anxiety phenotypes to identify more explanatory functional variation.
Facing Autism in New Brunswick: IMFAR 2012 Preconference Highlights: Oxytocin, IPADs and the Autism Speaks Autism Treatment...
I will be writing more about each speakers presentation when time permits. I was very interested in Dr. Nanit Gordons presentation about Oxytocins Impact on Social Cognitive Brain Function in Youth with ASD which seemed to follow directly from a presentation I heard earlier in a preconference session about parental behaviors and childrens capacity to become members of the social group, understand complex social signals and develop social collaboration. I reference that session in paragraph 2). Dr. Gordon presented data including fMRI images showing the effect of Oxytocin on areas of the brain important to the aforementioned social capacities. Oxytocin was one of the response items to certain types of interaction, particularly parental interaction. My concern and my questions concerned whether if parental interaction increases a hormonal response, oxytocin, which improves capacity for at risk children to develop social capacity does that imply that our current research is indicating a return ...

NCIRE Researcher Directory
The Role of Oxytocin as a Potential Biomarker for Psychosis Dr. Woolley has been studying the underpinnings of social deficits in schizophrenia and is currently examining oxytocins potential as a treatment for the social dysfunction observed in patients with schizophrenia. Individuals with schizophrenia often demonstrate significant social cognitive deficits that can impair the formation and maintenance of healthy relationships, and negatively impact social interactions and community participation. However, there are currently no pharmacological treatments available to target these deficits. In healthy individuals, the natural hormone oxytocin has been shown to enhance social abilities such as understanding emotions and trusting others. Thus, a primary focus of our research has been to examine whether supplementary oxytocin administration can improve social cognition in individuals with schizophrenia, which may ultimately lead to stronger relationships, improved social and occupational ...

Court Hears Misuse of Syntocinon Resulted in Birth Injuries - UK Medical Negligence
The Dublin High Court has heard that the misuse of syntocinon resulted in birth injuries to a young girl who now suffers from dyskinetic cerebral palsy.. Grace Orchard (8) from Carrigaline in County Cork was born at St Finbarr´s Maternity Hospital on 23rd February 2006. Prior to her delivery, her mother had been administered the drug syntocinon to speed up her contractions.. However, syntocinon also has the effect of exacerbating foetal distress and rather than conduct a Caesarean section on her mother, Grace was delivered by forceps after four previous attempts to bring her into the world - including one using a vacuum cup - had failed.. Grace had to be resuscitated after she was born, and was in a poor condition due to the trauma she had suffered in the womb. She was subsequently diagnosed with dyskinetic cerebral palsy which - according to her solicitor - was attributable to appalling poor handling by hospital staff during her delivery.. Through her mother - Deidre O´Callaghan - Grace ...
Derics MindBlog: Testosterone decreases trust.
Trust plays an important role in the formation and maintenance of human social relationships. But trusting others is associated with a cost, given the prevalence of cheaters and deceivers in human society. Recent research has shown that the peptide hormone oxytocin increases trust in humans. However, oxytocin also makes individuals susceptible to betrayal, because under influence of oxytocin, subjects perseverate in giving trust to others they know are untrustworthy. Testosterone, a steroid hormone associated with competition and dominance, is often viewed as an inhibitor of sociality, and may have antagonistic properties with oxytocin. The following experiment tests this possibility in a placebo-controlled, within-subjects design involving the administration of testosterone to 24 female subjects. We show that compared with the placebo, testosterone significantly decreases interpersonal trust, and, as further analyses established, this effect is determined by those who give trust easily. We ...

Biology Underlying Social and Emotional Profiles by Krizchelle Magtoto
This proposal research focuses on the biology underlying prosociality, which centers on emotions and behaviors that benefit others, in mother-baby-grandmother triads. One specific aim will center on how moral elevation, an emotional state generated through witnessing great acts of compassion, is related to caregiving behaviors and variations in the oxytocin system, a hormone important for an array of prosocial behaviors, including social bonding. In addition, the mothers and grandmothers will answer questionnaires to capture other aspects of their experiences. Our main investigation is to show that the emotional state of moral elevation is linked to epigenetic and genetic profiles of the oxytocin receptor gene, autonomic physiology, psychological profiles, behavioral displays, and oxytocin release. Altogether, this multimethod approach will explore the relationship between static (genetic) and dynamic (hormone, epigenetic) oxytocinergic profiles in the context of socioemotional processing influenced by

So, this study is suggesting that oxytocin, the love and bonding neurotransmitter, may play a bigger role in other activities than previously thought. This makes a lot of sense intuitively - of course, if you are in a state of liking, bonding, attraction, inhibition-reduction, and novelty-seeking, you are more likely to be creative, or be able to quickly adopt new ideas or new ways of thinking.. http://scan.oxfordjournals.org/content/early/2013/07/16/scan.nst094.abstract Oxytonergic circuitry sustains and enables creative cognition in humans. Using double-blind placebo-controlled between-subjects designs, Studies 3-6 (N = 191) finally showed that intranasal oxytocin (vs matching placebo) reduced analytical reasoning, and increased holistic processing, divergent thinking and creative performance. We conclude that the oxytonergic circuitry sustains and enables the day-to-day creativity humans need for survival and prosperity and discuss implications. . ...

Mothers Love Hormone Is Found To Influence Infants Social Behavior - INDUSTRY NEWS
Women have a very important hormone named oxytocin that is found to play a huge role in building social interaction and relationships in mammals, especially humans. This hormone is also found to help connect us to others. The trust, closeness, pleasant touch, eye contact, and empathy are all triggered in an individual with the help of the hormone. The oxytocin levels in the mother are found to have an impact on the childs behavior and also help mothers build a stronger bond with their baby. According to Tobias Grossmann from the Max Planck Institute and Jessica Connelly and Kathleen Krol from the University of Virginia, the development of oxytocin system in a child is found to rely on the mothers behavior.. During childhood, an individual has his/her systems maturing either physiologically or behavior-wise as a step to adulthood. Oxytocin plays an important role in early social, perceptual, & cognitive functions and even complex social behaviors also depend on the hormone. The recent study has ...

Sociopath World: The Science of Heartlessness
S]tudies are finding that oxytocin can increase the amount of money people will donate to a charity. One study in particular lent credence to the time honored method charities use to pull money from magazine readers: Feature a woebegone child in your advertisement. In the study, researchers had subjects watch a tearjerker film of a father talking about his sons brain tumor. They sampled subjects blood before and after the film. Following the film the blood was awash in oxytocin, and their donations to charity rose 47 percent, compared to those of subjects who saw a film of the same father talking about a trip to the zoo. The tearjerker technique was more effective on women than men. Experiments wherein people sniff oxytocin to bolster the chemical in their brain show that the chemical may work in two ways. It may operate first by dampening our natural fear of one another. Oxytocin is very active in the amygdala, which monitors the world for danger. Extra oxytocin fights fear. Then, with that ...
The gene responsible for social memory
Scientists recently found the gene responsible for constructing social memory. According to the July issue of Nature Genetics, researchers at Emory University School of Medicine in Atlanta, Georgia, discovered that the oxytocin gene enables an individual to recognize someone previously encountered.. If the oxytocin gene is missing or defective, then severe deficits in social memory occur. Without this fundamental ability, even your own mother would remain a stranger, study author James T. Winslow told the press. With the help of some transgenic or knockout male mice who lacked the oxytocin gene, researchers were able to expose the link between genetics and social memory. In order to test the social behaviors of mice, Winslow and his team closely observed the way mice use their sense of smell. A normal male mouse will use its sense of smell in order to get to know a female mouse until she becomes familiar. If a male and female are reintroduced 30 or 60 minutes after separation, the male ...

Background: Caesarean section is one of the most commonly performed major operations in women throughout the world. Rates are escalating, with studies from the United States of America, the United Kingdom, China and the Republic of Ireland reporting rates between 20% and 25%. Operative morbidity includes haemorrhage, anaemia, blood transfusion and in severe cases, maternal death. The value of routine oxytocics in the third stage of vaginal birth has been well established and it has been assumed that these benefits apply to caesarean delivery as well. A slow bolus dose of oxytocin is recommended following delivery of the baby at caesarean section. Some clinicians use an additional infusion of oxytocin for a further period following the procedure. Intravenous oxytocin has a very short half-life (4?10 minutes) therefore the potential advantage of an oxytocin infusion is that it maintains uterine contractility throughout the surgical procedure and immediate postpartum period, when most... ...
