Ovariectomy
The surgical removal of one or both ovaries.
Castration
Surgical removal or artificial destruction of gonads.
Estradiol
The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids.
Estrogens
Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds.
Ovary
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.
Progesterone
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.
Uterus
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.

The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.

Relaxin is a potent renal vasodilator in conscious rats. (1/4238)

The kidneys and other nonreproductive organs vasodilate during early gestation; however, the "pregnancy hormones" responsible for the profound vasodilation of the renal circulation during pregnancy are unknown. We hypothesized that the ovarian hormone relaxin (RLX) contributes. Therefore, we tested whether the administration of RLX elicits renal vasodilation and hyperfiltration in conscious adult, intact female rats. After several days of treatment with either purified porcine RLX or recombinant human RLX 2 (rhRLX), effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) increased by 20%-40%. Comparable renal vasodilation and hyperfiltration was also observed in ovariectomized rats, suggesting that estrogen and progesterone are unnecessary for the renal response to rhRLX. The nitric oxide synthase inhibitor Nomega-nitro-L-arginine methyl ester completely abrogated the increase in ERPF and GFR elicited by chronic administration of purified porcine RLX. In contrast, the renal vasoconstrictory response to angiotensin II was attenuated by the RLX treatment. Short-term infusion of purified porcine RLX to conscious rats over several hours failed to increase ERPF and GFR. Plasma osmolality was consistently reduced by the chronic administration of both RLX preparations. In conclusion, the renal and osmoregulatory effects of chronic RLX administration to conscious rats resemble the physiological changes of pregnancy in several respects: (a) marked increases in ERPF and GFR with a mediatory role for nitric oxide; (b) attenuation of the renal circulatory response to angiotensin II; and (c) reduction in plasma osmolality.  (+info)

Steroid regulation of retinol-binding protein in the ovine oviduct. (2/4238)

Two studies were conducted to identify retinol-binding protein (RBP) expression in the ovine oviduct and to determine the role of ovarian steroids in its regulation. Ewes were salpingectomized on Days 1, 5, or 10 of their respective estrous cycles, and oviducts were homogenized for RNA analysis, fixed for immunocytochemistry (ICC), or cultured for 24 h for protein analysis. ICC localized RBP to the epithelium of all oviducts. RBP synthesis was demonstrated by immunoprecipitation of radiolabeled RBP from the medium of oviductal explant cultures. Explant culture medium from oviducts harvested on Day 1 contained significantly more RBP than medium from oviducts collected on Days 5 or 10. Slot-blot analysis demonstrated that steady-state RBP mRNA levels were significantly higher on Day 1 than Day 5 or 10. In the second experiment, ovariectomized ewes were treated with estradiol-17beta (E2), progesterone (P4), E2+P4 (E2+P4), or vehicle control, and oviducts were analyzed as above. P4 alone or in combination with E2 significantly reduced steady-state RBP mRNA levels compared to those in E2-treated animals. Oviductal explants from E2- and E2+P4-treated animals released 3- to 5-fold more RBP into the medium than control and P4 treatments as determined by ELISA. RBP synthesis of metabolically labeled RBP was increased by E2 and E2+P4 treatments. This study demonstrates that P4 applied on an estradiol background negatively regulates RBP gene expression in the oviduct whereas estradiol appears to stimulate RBP synthesis and secretion.  (+info)

Effect of shellfish calcium on the apparent absorption of calcium and bone metabolism in ovariectomized rats. (3/4238)

Fossil shellfish powder (FS) and Ezo giant scallop shell powder (EG) were rendered soluble with lactate and citrate under decompression (FSEx and EGEx, respectively) and we examined the effects of lactate-citrate solubilization of FS and EG on mineral absorption, tissue mineral contents, serum biochemical indices and bone mineral density (BMD) in ovariectomized (OVX) rats. The apparent absorption ratios of minerals tended to be high in the rats fed with the solubilized mineral sources, those in the FSEx group being significantly higher than in the FS group. There was no significant difference in the tibia mineral content among the OVX groups. BMD at the distal femoral diaphysis was significantly increased by FSEx and EGEx feeding. It is suggested that solubilization with lactate and citrate under decompression increased the solubility and bioavailability of calcium from such natural sources of shellfish calcium as FS and EG.  (+info)

Expression of calcium binding protein D-9k messenger RNA in the mouse uterine endometrium during implantation. (4/4238)

To investigate the molecular mechanisms of implantation, we constructed a cDNA library of mouse uteri enriched with pregnancy-induced genes by subtractive hybridization and polymerase chain reaction (PCR). One of the isolated clones was the cDNA for the calcium binding protein D-9k (Cabp9k), which is considered to regulate intracytoplasmic concentration and transport of free calcium ions. Northern blot and in-situ hybridization analyses demonstrated that the Cabp9k mRNA was expressed in the endometrial epithelia, both luminal and glandular, in the uterus at the time of implantation. On pregnancy day 5 it was detected in the luminal, but not in the glandular, epithelia. In the oophorectomized adult mice, progesterone enhanced Cabp9k mRNA expression in the uterus, whereas oestrogen did not. Consistent with this, a nucleotide change was identified in the first intron of mouse Cabp9k gene corresponding to the oestrogen responsive element in the rat Cabp9k gene. Transfer of embryos into the uterine cavity of pseudopregnant mice reduced the expression of Cabp9k mRNA in the glandular epithelium, suggesting that Cabp9k mRNA expression is also regulated by embryonal signal(s). These findings demonstrated that Cabp9k mRNA is expressed in the endometrial epithelia during the implantation period under the control of progesterone and the presence of embryo, and suggest that CaBP9k plays a role in implantation by regulating the local calcium concentrations.  (+info)

Estrogen provides neuroprotection in transient forebrain ischemia through perfusion-independent mechanisms in rats. (5/4238)

BACKGROUND AND PURPOSE: Estrogen-related neuroprotection in association with animal models of transient forebrain and focal ischemia has been documented in several recent reports. Some of those studies indicated that part of that benefit was a function of improved intraischemic vasodilating capacity. In the present study we examined whether chronic estrogen depletion and repletion affected ischemic neuropathology through perfusion-independent mechanisms. METHODS: Normal, ovariectomized (OVX), and OVX female rats treated with 17beta-estradiol (E2) were subjected to 30 minutes of transient forebrain ischemia (right common carotid occlusion plus hemorrhagic hypotension) and reperfusion. Neurological function and brain histopathology were assessed over the 72-hour recovery period. In all rats, preischemic and intraischemic cortical cerebral blood flow (CBF) levels were monitored with laser-Doppler flowmetry. In additional rats, CBF changes in the striatum and hippocampus were also monitored with laser-Doppler flowmetry probes and radiolabeled microspheres. In each experiment, the level of ischemia was targeted to a 75% to 80% reduction in cortical CBF. RESULTS: The similarity in ischemic severity among groups was supported by measurements of comparable patterns of electroencephalographic power changes during the ischemic period. Compared with normal females, OVX rats showed diminished neurological outcomes and more severe histopathology in the hippocampus and striatum. Two-week treatment of OVX rats with E2 was accompanied by postischemic neuropathological changes similar to those seen in normal females. Intraischemic CBF reductions in the hippocampus and striatum were similar in all groups (to 35% to 50% of the preischemic value) but significantly less than the cortical CBF reductions. CONCLUSIONS: These findings indicate that estrogen provides ischemic neuroprotection through mechanisms unrelated to improvement of intraischemic cerebral perfusion.  (+info)

Androgen influence on lacrimal gland apoptosis, necrosis, and lymphocytic infiltration. (6/4238)

PURPOSE: Previous studies have shown that ovariectomy and hypophysectomy cause regression of the lacrimal gland and have implicated androgens as trophic hormones that support the gland. The purposes of this study were to test the hypothesis that glandular regression after ovariectomy is due to apoptosis, to identify the cell type or types that undergo apoptosis, to survey the time course of the apoptosis, and to determine whether ovariectomy-induced apoptosis could be prevented by dihydrotestosterone (DHT) treatment. METHODS: Groups of sexually mature female New Zealand White rabbits were ovariectomized and killed at various time periods up to 9 days. Additional groups of ovariectomized rabbits were treated with 4 mg/kg DHT per day. At each time period, sham-operated rabbits were used as controls. Lacrimal glands were removed and processed for analysis of apoptosis as assessed by DNA fragmentation and for morphologic examination. DNA fragmentation was determined using the TdT-dUTP terminal nick-end labeling assay and by agarose gel electrophoresis. Labeled nuclei were quantified by automated densitometry. Sections were also stained for RTLA (rabbit thymic lymphocyte antigen), rabbit CD18, and La antigen. Morphology was evaluated by both light and electron microscopy. RESULTS: The time course of apoptosis exhibited two phases, a rapid and transient phase and a second prolonged phase. A transient phase peaked at approximately 4 to 6 hours after ovariectomy. The values for degraded DNA as a percentage of total nuclear area were 4.29%+/-0.79% and 4.26%+/-0.54%, respectively. The values for sham-operated controls examined at the same time periods were 1.77%+/-0.08% and 0.82%+/-0.21%, respectively. The percentage of degraded DNA at 24 hours after ovariectomy was not different from controls examined at the same interval after sham operation. The percentage of degraded DNA 6 days after ovariectomy was significantly increased (8.5%+/-2.4%), compared with sham-operated animals at the same time period (0.68%+/-0.03%). DNA laddering was more pronounced after ovariectomy. Dihydrotestosterone treatment in ovariectomized rabbits suppressed the increase in DNA degradation. Morphologic examination of lacrimal gland sections indicated that ovariectomy caused apoptosis of interstitial cells rather than acinar or ductal epithelial cells. Tissue taken 4 hours and 6 days after ovariectomy showed nuclear chromatin condensation principally in plasma cells. Increased numbers of macrophages were also evident. Significant levels of cell degeneration and cell debris, characteristic of necrosis, were observed in acinar regions 6 days after ovariectomy. Dihydrotestosterone prevented this necrosis. Increased numbers of RTLA+, CD18+, and La+ interstitial cells were also evident 6 days after ovariectomy. In addition, ovariectomy increased La expression in ductal cells. Dihydrotestosterone treatment prevented the increase in numbers of lymphoid cells and La expression. Dihydrotestosterone also promoted the appearance of mitotic figures in acinar cells and increased the sizes of acini by 43% (P < 0.05). CONCLUSIONS: Glandular atrophy observed after ovariectomy is likely to proceed by necrosis of acinar cells rather than apoptosis. This process begins with an apparent time lag after a rapid phase of interstitial cell apoptosis. These processes are accompanied by increased lymphocytic infiltration. These results suggest that a critical level of androgen is necessary to maintain lacrimal gland structure and function and that a decrease in available androgen below this level could trigger lacrimal gland apoptosis and necrosis, and an autoimmune response. Because apoptotic and necrotic cell fragments may be sources of autoantigens that can be processed and presented to initiate an autoimmune reaction, we surmise that cell death triggered by androgen withdrawal may trigger an autoimmune response such as that encountered in Sjogren's syndrome.

Effect of long-term food restriction on pituitary sensitivity to cLHRH-I in broiler breeder females. (7/4238)

The effect of long-term food restriction on the sensitivity of the pituitary to exogenously administered chicken luteinizing hormone releasing hormone I (cLHRH-I) was investigated in three groups of broiler breeder females fed ad libitum, fed a restricted quantity of food or fed a restricted quantity of food to obtain an intermediate body weight between those of the first two groups. At 16 weeks of age, basal FSH release was higher in ad libitum fed birds, culminating in ovarian development and subsequent oestradiol production by the small follicles. At this age, LH secretion was independent of ovarian feedback factors. In all groups, cLHRH-I was most active in releasing LH in intact and ovariectomized animals and, to a lesser extent, in releasing FSH in ovariectomized birds. At 39 weeks of age, basal FSH concentrations were similar among intact animals of all groups, whereas LH concentrations differed among groups, with higher values in the restricted birds. This food effect was enhanced in ovariectomized birds. Furthermore, the high response to cLHRH-I in the ovariectomized, restricted birds compared with the ad libitum, ovariectomized group suggests an improved sensitivity of the hypothalamic-pituitary axis. In conclusion, birds fed ad libitum showed the highest responsiveness to ovarian factors and to cLHRH-I in releasing FSH in the period before sexual maturity. No effect of amount of feeding could be observed for LH. However, during the egg laying period, LH release by cLHRH-I was highly dependent on amount of feeding and on ovarian feedback regulation. This finding indicates that the amount of feeding can modify the sensitivity of the pituitary to cLHRH-I, and possibly to gonadal hormones, during the laying period.  (+info)

Suppression of the secretion of luteinizing hormone due to isolation/restraint stress in gonadectomised rams and ewes is influenced by sex steroids. (8/4238)

In this study we used an isolation/restraint stress to test the hypothesis that stress will affect the secretion of LH differently in gonadectomised rams and ewes treated with different combinations of sex steroids. Romney Marsh sheep were gonadectomised two weeks prior to these experiments. In the first experiment male and female sheep were treated with vehicle or different sex steroids for 7 days prior to the application of the isolation/restraint stress. Male sheep received either i.m. oil (control rams) or 6 mg testosterone propionate injections every 12 h. Female sheep were given empty s.c. implants (control ewes), or 2x1 cm s.c. implants containing oestradiol, or an intravaginal controlled internal drug release device containing 0.3 g progesterone, or the combination of oestradiol and progesterone. There were four animals in each group. On the day of application of the isolation/restraint stress, blood samples were collected every 10 min for 16 h for the subsequent measurement of plasma LH and cortisol concentrations. After 8 h the stress was applied for 4 h. Two weeks later, blood samples were collected for a further 16 h from the control rams and ewes, but on this day no stress was imposed. In the second experiment, separate control gonadectomised rams and ewes (n=4/group) were studied for 7 h on 3 consecutive days, when separate treatments were applied. On day 1, the animals received no treatment; on day 2, isolation/restraint stress was applied after 3 h; and on day 3, an i. v. injection of 2 microg/kg ACTH1-24 was given after 3 h. On each day, blood samples were collected every 10 min and the LH response to the i.v. injection of 500 ng GnRH administered after 5 h of sampling was measured. In Experiment 1, the secretion of LH was suppressed during isolation/restraint in all groups but the parameters of LH secretion (LH pulse frequency and amplitude) that were affected varied between groups. In control rams, LH pulse amplitude, and not frequency, was decreased during isolation/restraint whereas in rams treated with testosterone propionate the stressor reduced pulse frequency and not amplitude. In control ewes, isolation/restraint decreased LH pulse frequency but not amplitude. Isolation/restraint reduced both LH pulse frequency and amplitude in ewes treated with oestradiol, LH pulse frequency in ewes treated with progesterone and only LH pulse amplitude in ewes treated with both oestradiol and progesterone. There was no change in LH secretion during the day of no stress. Plasma concentrations of cortisol were higher during isolation/restraint than on the day of no stress. On the day of isolation/restraint maximal concentrations of cortisol were observed during the application of the stressor but there were no differences between groups in the magnitude of this response. In Experiment 2, isolation/restraint reduced the LH response to GnRH in rams but not ewes and ACTH reduced the LH response to GnRH both in rams and ewes. Our results show that the mechanism(s) by which isolation/restraint stress suppresses LH secretion in sheep is influenced by sex steroids. The predominance of particular sex steroids in the circulation may affect the extent to which stress inhibits the secretion of GnRH from the hypothalamus and/or the responsiveness of the pituitary gland to the actions of GnRH. There are also differences between the sexes in the effects of stress on LH secretion that are independent of the sex steroids.  (+info)

Ovariectomy may put younger women at risk for an earlier death
To conduct this study, Dr. Rocca and colleagues followed women who had undergone unilateral or bilateral ovariectomy between 1950 and 1987 while residing in Olmsted County, Minn., home of Mayo Clinic. All of these women had the surgery prior to menopause and for reasons other than cancer. The study evaluated 1,293 women with unilateral ovariectomy, 1,097 women with bilateral ovariectomy and, for comparison, 2,390 women who had not undergone ovariectomy. All women were followed until their deaths or until the end of the study, which was staggered between 2001 and 2006, via a combination of interviews with the women or a surviving relative, medical records and death certificates. A unique strength of this study, according to the investigators, was a 25- to 30-year median follow-up time. A total of 1,292 ...

N2 - The effect of underfeeding over glucose metabolism in uteri isolated from ovariectomized and non-ovariectomized rats subjected to a restricted diet for 25 days (50% of the normal food intake), was studied. Underfeeding decreases 14CO2 formation from U14 C-glucose in intact animal uteri. While in ovariectomized rats (25 days), the effect is the opposite. The addition of morphine 10-6 M to the medium does not affect rats fed ad libitum. However, 14CO2 levels increase significantly in intact animals receiving a restricted diet. In ovariectomized ...

Rationale: There is a special role for estrogens in preventing and curing cardiovascular disease in women. Soy isoflavone (SI), a soy-derived phytoestrogen, is a group of biologically active plant substances with chemical structures which are similar to that of an endogenous estrogen-estradiol.. Objective: We ought to elucidate possible mechanism of SI to improve myocardial ischemia/reperfusion (MI/R) injury in ovariectomized rats.. Methods and Results: Female SD rats were underwent bilateral ovariectomy or sham ovariectomy. One week later, rats were randomly divided into several groups and began to feed soy-free chow: sham ovariectomy operation (control group), ovariectomy with MI/R or ovariectomy with sham MI/R. Other ovariectomy rats were given different doses of SI dissolved in 0.5% carboxymethycellulose (CMC-Na) by gavage. Additional ovariectomy rats were administrated with the same volume of CMC-Na by gavage or 50 μg/kg·d of 17β-estradiol (E2) by subcutaneous injection. After four-week ...

Endogenous Estrogen and Acetylcholine-Induced Vasodilation in Normotensive Women | HypertensionEndogenous Estrogen and Acetylcholine-Induced Vasodilation in Normotensive Women | Hypertension
The present study was designed to test the effect of acute endogenous estrogen deprivation on endothelium-dependent vasodilation in women in reproductive age. Therefore, in a group of female patients who underwent bilateral ovariectomy for uterine leiomyoma, we evaluated the forearm vascular response to acetylcholine and sodium nitroprusside, an endothelium-dependent and -independent vasodilator, respectively. As control subjects we selected healthy women well matched with the study group population for demographic and clinical parameters. Particular attention was paid to risk factors impairing endothelial function such as age, blood pressure, phase of the menstrual cycle, lipid and glucose profile, and smoking history. In the two study populations, the response to acetylcholine and sodium nitroprusside was similar, indicating preserved endothelium-dependent vasodilation in patients with leiomyoma. In contrast, after bilateral ovariectomy, the response to acetylcholine was found to be reduced ...

Bilateral Oophorectomy, Body Mass Index, and Mortality in U.S. Women Aged 40 Years and Older | Cancer Prevention ResearchBilateral Oophorectomy, Body Mass Index, and Mortality in U.S. Women Aged 40 Years and Older | Cancer Prevention Research
To our knowledge, this is the first population-based study to establish a link between oophorectomy, adiposity, and mortality. We identified a subgroup of women who were at a greater risk of death following oophorectomy. Obese women who underwent oophorectomy before the age of 40 years had nearly 2-fold increased mortality, primarily due to CVD, compared with nonobese women with intact ovaries. The magnitude of this effect was greater than that expected, given the independent effects of both obesity and oophorectomy on mortality. Furthermore, among women who did not report use of HRT, obese women who had an oophorectomy before the age of 40 years were nearly 3 times more likely to die than nonobese women with intact ovaries. This relationship persisted after excluding those with oophorectomy conducted before the age of 35 years.. A few population-based, cross-sectional studies have shown an association between oophorectomy and adiposity. A study of 1,052 women ages 40 to 69 years in Norway ...

Orthosilicic Acid Increases Bone Density in Ovariectomized Rats | Osteoporosis-Studies
Silicon (Si) deficiency in animals results in bone defects. Choline-stabilized orthosilicic acid (ch-OSA) was found to have a high bioavailability compared to other Si supplements. The effect of ch-OSA supplementation was investigated on bone loss in aged ovariectomized (OVX) rats. Female Wistar rats (n = 58, age 9 months) were randomized in three groups. One group was sham-operated (sham, n = 21), and bilateral OVX was performed in the other two groups. OVX rats were supplemented orally with ch-OSA over 30 weeks (OVX1, n = 20; 1 mg Si/kg body weight daily) or used as controls (OVX0, n = 17). The serum Si concentration and the 24-hour urinary Si excretion of supplemented OVX rats was significantly higher compared to sham and OVX controls. Supplementation with ch-OSA significantly but partially reversed the decrease in Ca excretion, which was observed after OVX. The increase in bone turnover in OVX rats tended to be reduced by ch-OSA supplementation. ch-OSA supplementation increased significantly ...

Sex steroid regulation of the inflammatory response: sympathoadrenal dependence in the female rat. - Semantic ScholarSex steroid regulation of the inflammatory response: sympathoadrenal dependence in the female rat. - Semantic Scholar
To investigate the role of sex steroids in sex differences in the response of rats to the potent inflammatory mediator bradykinin (BK), we evaluated the effect of sex steroid manipulation on the magnitude of BK-induced synovial plasma extravasation (PE). The magnitude of BK-induced PE is markedly less in females. Ovariectomy of female rats increased BK-induced PE, and administration of 17beta-estradiol to ovariectomized female rats reconstituted the female phenotype. Castration in male rats decreased BK-induced PE, and administration of testosterone or its nonmetabolizable analog dihydrotestosterone reconstituted the male phenotype. The results of these experiments strongly support the role of both male and female sex steroids in sex differences in the inflammatory response. Because the stress axes are sexually dimorphic and are important in the regulation of the inflammatory response, we evaluated the contribution of the hypothalamic-pituitary-adrenal and the sympathoadrenal axes to sex differences in

OVX rat studies. Animals, diets, and surgery. Animal protocols were approved by the Animal Care and Use Committee at SmithKline Beecham Pharmaceuticals Inc. Six-month-old virgin Sprague-Dawley rats were purchased from Charles River Laboratories Inc. (Wilmington, Massachusetts, USA). They were provided with unrestricted access to tap water and commercial rodent chow (Diet 5001; PMI Nutrition International, Brentwood, Missouri, USA) throughout the study. When the rats were 7 months old, they were subjected either to a bilateral ovariectomy or to sham surgery, and then held for a further 3 months to allow the development of osteopenia. At that time, each rat was anesthetized with isoflurane, and bone mineral density (BMD) was quantified in the lumbar spine, distal femur, and proximal tibia by dual-energy x-ray absorptiometry (QDR-4500A; Hologic Inc., Waltham, Massachusetts, USA)..

Since pre-menopausal women are relatively protected from ischemia and heart disease, we tested the hypothesis that gender differences alter Ca2+ handling in rat cardiac mitochondria. Methods: Using cardiac mitochondria isolated from male, female, and ovariectomized Sprague-Dawley rats, we measured mitochondrial calcium transport, redox state, and membrane potential (Δψm) during exposure to a calcium bolus. Redox state was modulated using either succinate (S) or succinate and pyruvate (SP) as substrates. Results: Net Ca2+ uptake rates were significantly lower in female than male mitochondria using SP, substrate conditions that resulted in a lower redox state (NADH/NAD+). ...

The present study was undertaken to investigate the protective effects of ethanol extract from the root of Morinda Officinalis (RMO) on ovariectomy-induced bone loss. Administration of RMO extract increased trabecular bone mineral content and bone mineral density of tibia, improved the levels of phosphorus (P), calcium (Ca) and OPG, decreased the levels of DPD/Cr, TRAP, ACTH and corticosterone, but did not reverse the levels of ALP, TNF-α and IL-6 in serum of ovariectomized rats. These findings demonstrated that RMO extract reduced bone loss in ovariectomized rats, probably via the inhibition of bone resorption, but was not involved with bone formation. Anthraquinones and polysaccharides from Morinda officinals could be responsible for their antiosteoporotic activity, and the action mechanism of these constituents needs to be further studied. Therefore, RMO has the potential to develop a clinically useful antiosteoporotic agent.

The presence of asymmetry in the capacity of the left and right ovaries to secrete testosterone was analyzed by studying the effects of hemiovariectomy along the estrus cycle one hour after surgery. The effects of ether anesthesia on hormone serum levels were also analyzed. Bilateral ovariectomy and the extirpation of the left ovary performed on the day of proestrus resulted in significantly lower testosterone levels. Compared to the anesthetized group, the effects of perforating the peritoneum unilaterally varied according to the day of the estrous cycle and the side of the peritoneum surgery was performed on. Injecting atropine sulfate (ATR) to control or anesthetized rats on D1 resulted in a significant increase of testosterone serum levels. The effects of perforating the peritoneum on testosterone levels depended on the cholinergic innervation and varied along the estrous cycle. Blocking the cholinergic system before performing unilateral or bilateral ovariectomy had different effects depending on

Isoflavone Aglycone from Fermented Soy Pulp Prevents Osteoporosis in Ovariectomized RatsIsoflavone Aglycone from Fermented Soy Pulp Prevents Osteoporosis in Ovariectomized Rats
Abstract: This study was done to investigate the effects of fermented soy pulp on the osteoporosis in ovariectomized rats. Sprague-Dawley female rats were randomly assigned to four groups as Sham Control (SC), Ovariectomized Control (OC), Ovariectomized and Soy Pulp (OSP) fed and Ovariectomized and Fermented Soy Pulp (OFSP) fed. All rats were fed on purified diets, supplemented with non-fermented and fermented soy pulp on basic diet for 7 weeks. It was observed that isoflavone aglycone was very high in soy pulp fermented for 12 h in comparison to non-fermented soy pulp. Body weight of the rats increased significantly (p,0.05) in comparison to other groups. Atrophy of uterus in OFSP group was significantly (p,0.05) prevented in comparison to OC group. The concentration of estradiol in OFSP group was higher than those of OC and OSP groups. The bone density in OFSP group was significantly (p,0.05) higher than those of OC and OSP groups. The histopathology indicated that OFSP group has better ...

Gonadal steroids regulate dendritic spine density in hippocampal pyramidal cells in adulthood | Journal of NeuroscienceGonadal steroids regulate dendritic spine density in hippocampal pyramidal cells in adulthood | Journal of Neuroscience
Gonadal steroids are known to influence hippocampal physiology in adulthood. It is presently unknown whether gonadal steroids influence the morphology of hippocampal neurons in the adult intact rat brain. In order to determine whether female sex hormones influence hippocampal morphology in the intact adult, we performed Golgi impregnation on brains from ovariectomized rats and ovariectomized rats which received estradiol or estradiol and progesterone replacement. Removal of circulating gonadal steroids by ovariectomy of adult female rats resulted in a profound decrease in dendritic spine density in CA1 pyramidal cells of the hippocampus. Estradiol replacement prevented the observed decrease in dendritic spine density; progesterone augmented the effect of estradiol within a short time period (5 hr). Ovariectomy or gonadal steroid replacement did not affect spine density of CA3 pyramidal cells or granule cells of the dentate gyrus. These results demonstrate that gonadal steroids are necessary for ...

Hysterectomy for Benign Conditions: Prophylactic Oophorectomy or Ovary Conservation | MedCrave
The majority of cases with ovarian cancer are sporadic, not hereditary. Women with no documented germ line mutation or family history suspicious for genetic risk for ovarian cancer are considered to be at average risk. Women at increased genetic risk for ovarian cancer, especially those with BRCA1 and BRCA2 germ line mutations are at high risk of ovarian cancer and Lynch syndrome, and it is preferred to undergo risk-reducing bilateral salpingo-oophorectomy [10].. Several studies suggest a generally negative health effect when prophylactic bilateral salpingo-oophorectomy is performed before the age of menopause. Bilateral oophorectomy causes immediate drop in hormone levels of ovary that may affect long-term health. Women undergoing bilateral oophorectomy experience vaginal dryness, dyspareunia and loss of libido as a result of abrupt decline in circulating estrogen and testosterone levels [11]. Normally, for many years after menopause ovaries continue to produce androgens which are converted to ...

Maximum uterine blood flow occurred with 5 μg per kilogram of E1 and ≥ 20 μg per kilogram of E2α. Total uterine blood flow measured with isotope-labeled microspheres rose more than tenfold following 30 μg per kilogram of either estrogen, as did blood flow to the myometrium, endometrium, and uterine caruncles (p , 0.05). Distribution of uterine blood flow was unaltered. Cervical and vaginal blood flows increased ten-to twenty-fold with E1 and E2α, while mammary gland blood flow rose 54 and 77 per cent. Significant increases in adrenal and thyroid blood flows were documented. The only significant ...

Role of Exercise Training in Cardiovascular Autonomic Dysfunction and Mortality in Diabetic Ovariectomized Rats | HypertensionRole of Exercise Training in Cardiovascular Autonomic Dysfunction and Mortality in Diabetic Ovariectomized Rats | Hypertension
This study was performed to investigate the impact of autonomic dysfunction of the cardiovascular system and its association with the incidence of mortality in diabetic female rats that underwent ovarian hormone deprivation. In addition, we aimed to study the effects of exercise training, as a nonpharmacologic approach to treating diabetes and ovariectomy induced dysfunctions. Two important insights can be gained from the present study. First, the diabetic OVX rats presented increased autonomic dysfunction and mortality compared with normoglycemic rats. Second, TDO rats showed autonomic function improvement and a lower mortality than SDO rats.. Previous reports12,20 demonstrated that ovarian hormone deprivation in rats increases AP to levels higher than that observed in intact female and male rats.12,20-23 The AP values obtained in the SO rats in the present study were also increased in relation to the values documented in previous studies in intact female or male rats. Similarly, the incidence ...

1-(Morpholinomethyl)-4-phthalimido-piperidindione-2,6 (CG 603) had a greater therapeutic effect than bilateral ovariectomy, estrogen (mestranol, 17α-ethinylestradiol-3-methylether), or androgen (drostanolone propionate, 2α-methyldihydrotestosterone propionate, 2α-MDTP) on 7,12-dimethylbenzanthracene-induced tumors in Sprague-Dawley rats. The antitumor activity of CG 603 was equivalent to hypophysectomy. Combined treatment with CG 603 and ovariectomy or estrogen gave no significant increase in antitumor activity over that with CG 603 alone. The combined treatment with CG 603 and 2α-MDTP showed a significantly higher regression of tumor weight and tumor number than the treatment with CG 603 or 2α-MDTP alone. While CG 603 in higher concentrations decreases the body weight of experimental animals, the combination of CG 603 in lower concentration with the anabolically acting 2α-MDTP increases the body weight of the treated animals. CG 603 probably exerts its antitumor activity primarily via ...

A Chinese herbal preparation, QingE formula (QEF), has been used clinically for treating osteoporosis in postmenopausal women by virtue of its kidney-invigorating function; however, no evidence base links QEF to estrogen replacement therapy. In this study, we undertake a characterization of estrogenic activity of QEF using an in vivo model of ovariectomized (OVX) mice together with in vitro studies with the MCF-7 cells for further molecular characterization. OVX mice were treated intragastrically with QEF at doses of 0.85, 1.7, and 3.4 g/kg per day for 4 weeks. QEF treatments restored the estrus cycle and demonstrated significant estrogenic activity, as indicated by reversal of uterine atrophy (six-fold increase in uterine weight), reduction in rectal temperature, and increased expression (1.6-fold) of estrogen receptors (ERs) in the uterus. Notably, the largest changes in these three parameters were found at the lowest dose. At the highest dose of QEF, significant changes were found in adrenal ...

Female gender, which is abolished following ovariectomy and reproductive senescence, is associated with improved outcome following cerebral stroke. Estrogen replacement partially restores this benefit of the female gender but the effect of progesterone in hormone-deficient animals is currently unknown. We evaluated various outcomes following middle cerebral artery occlusion (MCAO) in ovariectomised female mice, with a physiologically relevant restoration of progesterone levels. Ovariectomised female mice had significantly elevated plasma (P=,0.05) and brain progesterone levels (P=,0.01) following implantation of a 21-day release pellet (50mg) compared with mice that received placebo implants 7 days prior to undergoing 60 min MCAO. Assessment of well-being (body weight recovery) and neurological score at 24h and 48h post-MCAO indicated that MCAO significantly worsened outcome compared with sham-operated mice but progesterone had no effect. MCAO resulted in a substantial lesion formation and a ...

Two experiments of divergent selection for uterine efficiency in rabbits were performed. Rabbit does were unilaterally ovariectomized and a laparoscopy was made at mid-gestation to observe the number of corpora lutea and implanted embryos in the functional genital tract. Selection was based on the number of fetuses which died between implantation and birth in the first experiment, and on litter size in the second one, both using BLUP on an animal model. This paper presents the average values of observed traits and their heritability. Results show that an effective overcrowding of one uterine hom was obtained at implantation. The additive genetic variability of embryonic survival seems to be greater than that of fetal survival. Some differences in heritabilities between intact and unilaterally ovariectomized females tend to appear ...

Impact of gonadectomy on blood pressure regulation in ageing male and female rats | Biology of Sex Differences | Full TextImpact of gonadectomy on blood pressure regulation in ageing male and female rats | Biology of Sex Differences | Full Text
Sexual dimorphism in blood pressure has been associated with differential expression of the angiotensin II (AII) receptors and with activity of the nervous system. It is generally accepted that ageing affects kidney function as well as autonomic nervous system and hormonal balance. Given that hypertension is more prevalent in men than women until women reach their seventh decade, we hypothesised that females would be relatively protected from adverse effects of ageing compared to males and that this would be mediated by the protective effect of ovarian steroids. Intact and gonadectomised male and female normotensive Wistar rats aged 6, 12 and 18 months were used to study renal function, blood pressure, heart rate, and blood pressure variability. We observed that intact females had lower levels of proteinuria and higher (12.5%) creatinine clearance compared to intact males and that this difference was abolished by castration but not by ovariectomy. Ovariectomy resulted in a change by 9% in heart rate,

Symptoms of Estrogen Deficiency and Quality of LifeSymptoms of Estrogen Deficiency and Quality of Life
Introduction: The quality of life of every individual is influenced by many different factors. For women in menopause, estrogen deficiency is undoubtedly one of these factors. Estrogen deficit leads to a series of symptoms, which may affect their quality of life to some extent. In the clinical practice, it is important to have a tool to assess the quality of life that is practical and is able not only to assess the quality of life. Aim: The aim of the research was to determine whether and to what extent the symptoms of estrogen deficiency occur in women during menopause and how they affect their quality of life. Method: The survey ran from July to October 2016 in a medical facility in Zlín. The research involved 284 women aged 45-60 years who suffered from the symptoms of estrogen deficiency. The incidence and severity of symptoms were assessed using the printed form of the Czech version of the Menopause Rating Scale questionnaire. Results: The respondents reported mostly mild or no problems. ...

Hormone therapy (HT) is reported to be deficient in improving learning and memory in older postmenopausal women according to recent clinical studies; however, the reason for failure is unknown. A window of opportunity for estrogen treatment is proposed to explain this deficiency. Here, we found that facilitation of memory extinction and long-term depression by 17β-estradiol (E2) was normal in mice 1 week after ovariectomy (OVXST), but it was impaired in mice 3 months after ovariectomy (OVXLT). High-throughput sequencing revealed a decrease of miR-221-5p, which promoted cannabinoid receptor 1 (CB1) ubiquitination by upregulation of Neurl1a/b in E2-treated OVXLT mice. Blood samples from postmenopausal women aged 56-65 indicated decreases of miR-221-5p and 2-arachidonoylglycerol compared with samples from perimenopausal women aged 46-55. Replenishing of miR-221-5p or treatment with a CB1 agonist rescued the impairment of fear extinction in E2-treated OVXLT mice. The present study demonstrates ...

An Endogenous SERM? | Science SignalingAn Endogenous SERM? | Science Signaling
Although estrogens have long been thought to be protective against cardiovascular disease, this assumption has been challenged by clinical trials that failed to corroborate such protective effects of hormone replacement therapy in postmenopausal women. Umetani et al. found that the cholesterol metabolite 27-hydroxycholesterol (27HC, which is found in atherosclerotic lesions) competed with estradiol for binding to estrogen receptor α and β (ERα and ERβ), inhibited estradiol-dependent activation of transcriptional activity of the receptors, and inhibited the estradiol-dependent association of ERβ with the transcriptional coactivator SRC-1. In mice fed diets rich in cholesterol and fat, hypercholesterolemia was associated with increased vascular concentrations of 27HC, so that it reached concentrations comparable to those affecting ER function. 27HC inhibited the estradiol-dependent increase in mRNA encoding inducible and endothelial nitric oxide synthase (iNOS and eNOS) in mouse aortic ...

Atrazine (ATR) blunts the hormone-induced luteinizing hormone (LH) surge, when administered by gavage (50-100 mg/kg/day for 4 days), in ovariectomized rats. In this study, we determined if comparable doses delivered either by gavage (bolus dose) or distributed in diet would reduce the LH surge and subsequently affect fertility in the intact female rat. ATR was administered daily to intact female Sprague-Dawley (SD) or Long Evans (LE) rats by gavage (0, 0.75 1.5, 3, 6, 10, 12, 50, or 100 mg/kg/day) or diet (0, 30, 100, 160, 500, 660, or 1460 ppm) during one complete 4-day estrous cycle, starting on day of estrus. Estrous status, corpora lutea, ova, and LH plasma concentrations were evaluated. A second cohort of animals was mated on the fourth treatment day. Fertility metrics were assessed on gestational day 20. A higher portion of LE rats had asynchronous estrous cycles when compared to SD rats both during pretreatment and in response to ATR (≥50 mg/kg). In contrast, bolus doses of ATR (≥50 mg/kg)

ABSTRACT Objective: Staphylococcus aureus infections remain associated with considerable morbidity and mortality in both hospitals and the community. There is little information regarding the role of ovarian hormones in infections caused by S. aureus. The aim of this study was to evaluate the effects of ovariectomy in the immune response induced by S. aureus. Methods: Female mice BALB/c were ovariectomized (OVX) to significantly reduce the level of ovarian hormones. We also used sham-operated animals. The mice were inoculated intraperitoneally with S. aureus. Blood samples were collected for leukocyte count and bacterial quantification. The uterus and spleen were removed and weighed to calculate the uterine and splenic indexes. Lungs were removed and fractionated for immunohistochemical analysis for macrophage detection (anti-CD68) and relative gene expression of IL-6, IL-1β and TNF-α by RT-PCR. Results: Ovariectomy enlarged spleen size and generally increased circulating lymphocytes. OVX ...

In Vivo Studies. Systemic inflammation and mortality were induced by intraperitoneal injection of Escherichia coli endotoxin [lipopolysaccharide (LPS)] into wild-type and PARP-1-deficient mice (Liaudet et al., 2000). To induce systemic inflammatory mediator production without mortality, LPS was injected at a dose of 1 mg/kg, followed by the measurement of TNF-α and macrophage inflammatory protein (MIP)-1α at 90 min, using enzyme-linked immunosorbent assay. To inhibit the catalytic activity of PARP in vivo, the phenanthridinone-based PARP inhibitor PJ34 (Jagtap et al., 2002) at 10 mg/kg or INO-1001 (Szabó et al., 2004; Jagtap et al., 2005) at 3 mg/kg were given i.p., as a 30-min pretreatment prior to the injection of LPS.. In some experiments, LPS (1 mg/kg i.p.) was given to ovariectomized female mice in the absence or presence of PARP inhibitor pretreatment (doses as above), followed by measurement of TNF at 90 min. In another set of experiments (in female mice), the dose of LPS was increased ...

Estrogen deprivation in postmenopausal women increases cardiovascular risk. Cardiovascular risk as a result of atherosclerosis is able to induce an inflammatory disease as far as cyclooxygenase-2 (COX-2) expression. The purpose of the study was to investigate the role of COX-2 on exercise training in female mice LDL-KO with or without ovariectomy. Results showed that ovariectomy induced a strong immunoexpression in atherosclerosis lesion of LDL-KO mice. Nevertheless, a down-regulation of COX-2 expression was detected in LDL-KO trained ovariectomized when compared to LDL-KO sedentary. Our results are consistent with the notion that exercise training is able to modulate COX-2 expression in LDL-KO mice as a result of COX-2 down-regulation.. ...

RNAi-mediated knockdown of InsR and/or IGF-IR inhibited growth of ER+ breast cancer cells adapted to hormone deprivation, but dual knockdown additively suppressed PI3K/AKT signaling. Pharmacologic blockade of InsR/IGF-IR with OSI-906 inhibited PI3K/AKT and LTED cell growth. OSI-906 also prevented the emergence of hormone-independent tumors, and suppressed growth of ER+ xenografts in ovariectomized mice. Blockade of IGF-IR alone was insufficient to prevent emergence of hormone-independent cells or suppress tumor growth, suggesting that dual inhibition of InsR and IGF-IR is necessary to prevent escape of ER+ breast cancer cells from estrogen dependence. Combined inhibition of ER and InsR/IGF-IR suppressed hormone-independent tumor growth more effectively than each intervention alone. Finally, an insulin/IGF-I-induced gene expression signature was predictive ...

Chen, K.<...
Dr Kai Chen is currently a Research Associate at the School of Molecular Sciences, UWA. He finished his medical and orthopaedic surgery training in China (2007 - 2015). He completed his PhD studies (2019) in Bone Biology under the supervision of Prof.Jiake Xu at UWA.. His current research interests focus on the pathogenesis of bone disorder such as ageing- and estrogen deficiency-induced osteoporosis. To achieve this, he recently developed a first-in-kind protocol to process bone samples for isotopic imaging at the nanoscale resolution by using ion microscopy. By using a stable-isotope labelling tracer, this cutting-edge technology will advance the imaging of bone niche to an unprecedented resolution. Dr Chen is also passionate about developing biomaterials that can promote bone repair. ...

Dr. Sanity: Medical ScaremongeringDr. Sanity: Medical Scaremongering
I know women who decided never to take hormone replacement therapy because of these studies. Some of them have never returned to feeling as well as they did pre-menopause. Others, it doesnt seem to bother much. I suspect there is considerable individual physiological variability associated with the number of estrogen receptors and such, which probably determines how sensitive one is to estrogen depletion. But it is an individual thing, and each individual should decide for themselves whether the risk is worth it or not. Everything in life is a trade-off, after all. It is only in a culture where litigation thrives that miracle drugs like HRT, or anti-inflammatory agents (e.g., Vioxx, Celebrex, Ibuprofen etc.) are damned because they have side effects. EVERY SINGLE DRUG HAS SIDE EFFECTS. Litigation is only possible if the indiviudal abrogates his/her own personal responsibility in determining what the risk versus benefit is for each medication they are prescribed ...

Oophorectomy Sucks - the risky bodyOophorectomy Sucks - the risky body
I get it: risk-reducing bilateral salpingo-oophorectomy (RRBSO) is the only proven way to protect high risk women from ovarian cancer, a disease that is particularly hard to detect, psychologically and physically devastating, and usually deadly. There are currently no accurate ways to screen for it in symptomless women and by the time symptoms do arise…

Vox Popoli: The ever-shifting Narrative
It is fairly common for ppl with allergies to have post nasal drip and an irritable choke/cough. However, one doesnt have seasonal allergy attacks Spring, Summer, Winter,and Fall, especially not for years on end. Add to the fact that anyone that is wealthy, has access to the top 1% of physicians in the world, if they were suffering from seasonal allergies to a degree such as they are presenting, she wouldve long been on a regime of allergy shots, cortisone, and she wouldve been on an antibiotic, days ago, preventing any bronchial issues turning into pneumonia. I know this, because Ive had them all my life, and Im nearly 50, and a woman. As for the hormonal/menopausal fluxes that can affect this and other health issues, shes nearly SEVENTY, ffs. Besides, I cannot think of a WORSE defense of a health issue, than suggesting estrogen depletion should be a consideration to give her a pass when her ONLY reason she has credibly given as to why anyone should ever possibly think to vote for her, is ...

Inflamação no tecido adiposo visceral em ratas ovariectomizadas : efeitos do treinamento resistido e da reposição de estrogêniInflamação no tecido adiposo visceral em ratas ovariectomizadas : efeitos do treinamento resistido e da reposição de estrogêni
The ovariectomy associated with decreased estrogen is associated with increased prevalence of obesity, a condition that increases the risk of metabolic syndrome. Evidence shows that inflammation-induced obesity in visceral adipose tissue (VAT) promotes deregulation in the expression of inflammatory cytokines. Hormone replacement (HR) and resistance training (RT) have beneficial effects on postmenopausal women, but it is unclear whether these interventions are effective in minimizing inflammation in VAT. The aim of this study was to evaluate the effects of RT and ER in adipocyte size, gene expression and protein concentration of inflammatory markers. Rats Sprague-Dowley females were divided into six groups: Sham-Sedentary (Sham-Sed), Ovariectomized Sedentary (Ovx-Sed), Sham-Trained (Sham-TR), Ovx-TR, Ovx-Sed-ER and Ovx-TR-ER. The ER was performed using Silastic® capsules. During the 12- week RT, the animals climbed a ladder with weights attached to the tails. The morphology was confirmed by ...
