Chloralose
Pentobarbital
A short-acting barbiturate that is effective as a sedative and hypnotic (but not as an anti-anxiety) agent and is usually given orally. It is prescribed more frequently for sleep induction than for sedation but, like similar agents, may lose its effectiveness by the second week of continued administration. (From AMA Drug Evaluations Annual, 1994, p236)
Cats
The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago. (From Walker's Mammals of the World, 6th ed, p801)

Vagus Nerve
The 10th cranial nerve. The vagus is a mixed nerve which contains somatic afferents (from skin in back of the ear and the external auditory meatus), visceral afferents (from the pharynx, larynx, thorax, and abdomen), parasympathetic efferents (to the thorax and abdomen), and efferents to striated muscle (of the larynx and pharynx).

Evoked Potentials
Electrical responses recorded from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported.
Hindlimb
Decerebrate State
A condition characterized by abnormal posturing of the limbs that is associated with injury to the brainstem. This may occur as a clinical manifestation or induced experimentally in animals. The extensor reflexes are exaggerated leading to rigid extension of the limbs accompanied by hyperreflexia and opisthotonus. This condition is usually caused by lesions which occur in the region of the brainstem that lies between the red nuclei and the vestibular nuclei. In contrast, decorticate rigidity is characterized by flexion of the elbows and wrists with extension of the legs and feet. The causative lesion for this condition is located above the red nuclei and usually consists of diffuse cerebral damage. (From Adams et al., Principles of Neurology, 6th ed, p358)
Medulla Oblongata
Respiration
The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (= OXYGEN CONSUMPTION) or cell respiration (= CELL RESPIRATION).
Sympathetic Nervous System
The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.

Carotid Body
A small cluster of chemoreceptive and supporting cells located near the bifurcation of the internal carotid artery. The carotid body, which is richly supplied with fenestrated capillaries, senses the pH, carbon dioxide, and oxygen concentrations in the blood and plays a crucial role in their homeostatic control.
Anesthetics
Vasopressins
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.

Game Theory
Theoretical construct used in applied mathematics to analyze certain situations in which there is an interplay between parties that may have similar, opposed, or mixed interests. In a typical game, decision-making "players," who each have their own goals, try to gain advantage over the other parties by anticipating each other's decisions; the game is finally resolved as a consequence of the players' decisions.
The actions of ether, alcohol and alkane general anaesthetics on GABAA and glycine receptors and the effects of TM2 and TM3 mutations. (1/124)
The actions of 13 general anaesthetics (diethyl ether, enflurane, isoflurane, methoxyflurane, sevoflurane, chloral hydrate, trifluoroethanol, tribromoethanol, tert-butanol, chloretone, brometone, trichloroethylene, and alpha-chloralose) were studied on agonist-activated Cl(-) currents at human GABA(A) alpha(2)beta(1), glycine alpha(1), and GABA(C) rho(1) receptors expressed in human embryonic kidney 293 cells. All 13 anaesthetics enhanced responses to submaximal (EC(20)) concentrations of agonist at GABA(A) and glycine receptors, except alpha-chloralose, which did not enhance responses at the glycine alpha(1) receptor. None of the anaesthetics studied potentiated GABA responses at the GABA(C) rho(1) receptor. Potentiation of submaximal agonist currents by the anaesthetics was studied at GABA(A) and glycine receptors harbouring mutations in putative transmembrane domains 2 and 3 within GABA(A) alpha(2), beta(1), or glycine alpha(1) receptor subunits: GABA(A) alpha(2)(S270I)beta(1), alpha(2)(A291W)beta(1), alpha(2)beta(1)(S265I), and alpha(2)beta(1)(M286W); glycine alpha(1)(S267I) and alpha(1)(A288W). For all anaesthetics studied except alpha-chloralose, at least one of the mutations above abolished drug potentiation of agonist responses at GABA(A) and glycine receptors. alpha-Chloralose produced efficacious direct activation of the GABA(A) alpha(2)beta(1) receptor (a 'GABA-mimetic' effect). The other 12 anaesthetics produced minimal or no direct activation of GABA(A) and glycine receptors. A non-anaesthetic isomer of alpha-chloralose, beta-chloralose, was inactive at GABA(A) and glycine receptors and did not antagonize the actions of alpha-chloralose at GABA(A) receptors. The implications of these findings for the molecular mechanisms of action of general anaesthetics at GABA(A) and glycine receptors are discussed. (+info)Effect of distension of the gallbladder on plasma renin activity in anesthetized pigs. (2/124)
BACKGROUND: Gallbladder pathology has been associated with cardiovascular disease. Recently, we showed that gallbladder distension in anesthetized pigs reflexly increased heart rate, arterial pressure, and coronary and renal vascular resistance through efferent sympathetic mechanisms. Renin release is affected by sympathetic output, and angiotensin liberation may result in vasoconstriction. This study was undertaken to determine whether gallbladder distension primarily causes a reflex change in plasma renin activity (PRA) and to assess its influence on observed pressor and coronary responses as well as on regional vascular resistance. METHODS AND RESULTS: In 34 alpha-chloralose-anesthetized pigs, balloons positioned within the gallbladder were distended for 30 minutes with volumes of Ringer's solution equal to those of withdrawn bile. In 19 pigs, gallbladder distension at constant heart rate, arterial pressure, and renal flow increased PRA in the absence of changes in urinary sodium excretion. This increase was abolished by cervical vagotomy, section of renal nerves, or blockade of beta-adrenergic receptors. In another 15 pigs, blockade of angiotensin II receptors significantly attenuated the pressor and coronary, mesenteric, and iliac vasoconstriction responses to gallbladder distension. CONCLUSIONS: The present study showed that innocuous gallbladder distension primarily caused a reflex increase in PRA. This increase, which involved afferent vagal pathways and efferent sympathetic mechanisms related to beta-adrenergic receptors, contributed significantly to the pressor and coronary, mesenteric, and iliac vasoconstriction responses to gallbladder distension. (+info)Nerve-evoked secretion of immunoglobulin A in relation to other proteins by parotid glands in anaesthetized rat. (3/124)
Secretion of fluid and proteins by salivary cells is under the control of parasympathetic and sympathetic autonomic nerves. In a recent study we have shown that, in the rat submandibular gland, autonomic nerves can also increase the secretion of IgA, a product of plasma cells secreted into saliva as SIgA (IgA bound to Secretory Component, the cleaved poly-immunoglobulin receptor). The present study aimed to determine if parotid secretion of SIgA is increased by autonomic nerves and to compare SIgA secretion with other parotid proteins stored and secreted by acinar and ductal cells. Assay of IgA in saliva evoked by parasympathetic nerve stimulation immediately following an extended rest period under anaesthesia indicated that it had been secreted into intraductal saliva in the absence of stimulation during the rest period. The mean rate of unstimulated IgA secretion (2.77+/-0.28 microg min(-1) g(-1)) and the 2.5-fold increase in IgA secretion evoked by parasympathetic stimulation were similar to results found previously in the rat submandibular gland. Sympathetic nerve stimulation increased SIgA secretion 2.7-fold, much less than in the submandibular gland. SDS-PAGE and Western blot analysis with anti-IgA and anti-Secretory Component antibodies confirmed that SIgA was the predominant form of IgA in saliva. Acinar-derived amylase and ductal-derived tissue kallikrein were more profoundly increased by parasympathetic and particularly sympathetic stimulation than SIgA. Overall, the results of the present study indicate that SIgA forms a prominent component of unstimulated parotid salivary protein secretion and that its secretion is similarly increased by stimulation of either autonomic nerve supply. The secretion of other parotid salivary proteins that are synthesized and stored by acinar or ductal cells is upregulated to a much greater extent by parasympathetic and particularly sympathetic stimulation. (+info)Gadolinium attenuates exercise pressor reflex in cats. (4/124)
The exercise pressor reflex, which arises from the contraction-induced stimulation of group III and IV muscle afferents, is widely believed to be evoked by metabolic stimuli signaling a mismatch between blood/oxygen demand and supply in the working muscles. Nevertheless, mechanical stimuli may also play a role in evoking the exercise pressor reflex. To determine this role, we examined the effect of gadolinium, which blocks mechanosensitive channels, on the exercise pressor reflex in both decerebrate and alpha-chloralose-anesthetized cats. We found that gadolinium (10 mM; 1 ml) injected into the femoral artery significantly attenuated the reflex pressor responses to static contraction of the triceps surae muscles and to stretch of the calcaneal (Achilles) tendon. In contrast, gadolinium had no effect on the reflex pressor response to femoral arterial injection of capsaicin (5 microg). In addition, gadolinium significantly attenuated the responses of group III muscle afferents, many of which are mechanically sensitive, to both static contraction and to tendon stretch. Gadolinium, however, had no effect on the responses of group IV muscle afferents, many of which are metabolically sensitive, to either static contraction or to capsaicin injection. We conclude that mechanical stimuli arising in contracting skeletal muscles contribute to the elicitation of the exercise pressor reflex. (+info)Potencies of doxapram and hypoxia in stimulating carotid-body chemoreceptors and ventilation in anesthetized cats. (5/124)
The effects of doxapram on carotid chemoreceptor activity and on ventilation (phrenic-nerve activity) were tested before and after denervation of the peripheral chemoreceptors in cats. Doxapram was found to be a potent stimulus to the carotid chemoreceptors; the stimulation produced by 1.0 mg/kg doxapram, iv, equalled that produced by a Pao2 of 38 torr. Doxapram also increased phrenic-nerve activity in doses as low as 0.2 mg/kg, iv. After denervation of the peripheral chemoreceptors, doxapram in doses as large as 6 mg/kg failed to stimulate ventilation. It is concluded that (in anesthetized cats) doxapram in doses of less than 6 mg/kg increases ventilation by direct stimulation of the carotid, and, probably, the aortic, chemoreceptors, not by a direct effect on the medullary respiratory center. (+info)Hemodynamic consequences of the combination of isoflurane anesthesia (1 MAC) and beta-adrenergic blockade in the dog. (6/124)
The hemodynamic response to the combination of isoflurane (1 MAC) and propranolol (0.5 mg/kg) was studied in 12 intact ventilated dogs following basal anesthesia with chloralose-urethane. When propranolol was administered during isoflurane anesthesia, stroke volume was maintained with a higher pulmonary capillary wedge pressure (3.2 plus or minus 0.7 mm Hg to 6.3 plus or minus 1.4 mm Hg), while systemic vascular resistance remained unchanged. When isoflurane was administered to the previously beta-adrenergically blocked dog, there were declines in systemic pressure and cardiac output (P smaller than 0.01) and in pulmonary arterial pressure and stroke volume (P smaller then 0.05), without change in systemic vascular resistance. When isoflurane was subsequently discontinued, these changes were reversed, and in addition, systemic vascular resistance increased (P smaller than 0.05). These data indicate that isoflurane has pharmacologic properties compatible with a peripheral beta-adrenergic stimulating action. (+info)Effect of clonidine on the excitability of vasomotor loci in the cat. (7/124)
1. The effect of clonidine on the direct excitability of hypothalamic, medullary and spinal vasomotor loci has been investigated in cats anaesthetized with chloralose. 2. Clonidine inhibited the excitability of these loci when it was localized to the central sites by intracerebroventricular, intravertebral arterial or intrathecal injection in very low doses (1-2 mug). 3. Topical application of clonidine (0.01 percent and 1.0 percent) to the floor of the fourth ventricle inhibited pressor responses evoked either by stimulation of medullary or hypothalamic vasomotor areas. Inhibition of the pressor responses was accompanied by hypotension and bradycardia in many experiments. 4. It appears that effects of clonidine on the vasomotor loci of the medulla oblongata and the spinal cord contribute to its hypotensive action. (+info)Effects of anesthesia on functional activation of cerebral blood flow and metabolism. (8/124)
Functional brain mapping based on changes in local cerebral blood flow (lCBF) or glucose utilization (lCMR(glc)) induced by functional activation is generally carried out in animals under anesthesia, usually alpha-chloralose because of its lesser effects on cardiovascular, respiratory, and reflex functions. Results of studies on the role of nitric oxide (NO) in the mechanism of functional activation of lCBF have differed in unanesthetized and anesthetized animals. NO synthase inhibition markedly attenuates or eliminates the lCBF responses in anesthetized animals but not in unanesthetized animals. The present study examines in conscious rats and rats anesthetized with alpha-chloralose the effects of vibrissal stimulation on lCMR(glc) and lCBF in the whisker-to-barrel cortex pathway and on the effects of NO synthase inhibition with N(G)-nitro-L-arginine methyl ester (L-NAME) on the magnitude of the responses. Anesthesia markedly reduced the lCBF and lCMR(glc) responses in the ventral posteromedial thalamic nucleus and barrel cortex but not in the spinal and principal trigeminal nuclei. L-NAME did not alter the lCBF responses in any of the structures of the pathway in the unanesthetized rats and also not in the trigeminal nuclei of the anesthetized rats. In the thalamus and sensory cortex of the anesthetized rats, where the lCBF responses to stimulation had already been drastically diminished by the anesthesia, L-NAME treatment resulted in loss of statistically significant activation of lCBF by vibrissal stimulation. These results indicate that NO does not mediate functional activation of lCBF under physiological conditions. (+info)

GABRA4
Gamma-aminobutyric acid receptor subunit alpha-4 is a protein that in humans is encoded by the GABRA4 gene.[5][6] GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. At least 16 distinct subunits of GABA-A receptors have been identified.[6] ...

(INN) (brand name Nopron) is a sedative-hypnotic drug of the phenylpiperazine group.[1][2] It has been used in the treatment of sleep disturbances since the early 1970s in several European countries including France, Italy, and Luxembourg.[3][4] It is commonly used with children and adolescents on account of its favorable safety and tolerability profile and lack of abuse potential.[5][6][7][8][9][10] Originally believed to act as an antihistamine and anticholinergic,[11] niaprazine was later discovered to have low or no binding affinity for the H1 and mACh receptors (Ki = , 1 μM), and was instead found to act as a potent and selective 5-HT2A and α1-adrenergic receptor antagonist (Ki = 75 nM and 86 nM, respectively).[12] It possesses low or no affinity for the 5-HT1A, 5-HT2B, D2, and β-adrenergic, as well as at SERT and VMAT (Ki = all , 1 μM), but it does have some affinity for the α2-adrenergic receptor (Ki = 730 nM),[12] likely acting as an antagonist there as well. Niaprazine ...
Captodiame
... (INN), also known as captodiamine, is an antihistamine sold under the trade names Covatine, Covatix, and Suvren which is used as a sedative and anxiolytic. The structure is related to diphenhydramine.[1] A 2004 study suggested captodiame may be helpful in preventing benzodiazepine withdrawal syndrome in people discontinuing benzodiazepine treatment.[1] In addition to its actions as an antihistamine, captodiamine has been found to act as a 5-HT2C receptor antagonist and σ1 receptor and D3 receptor agonist.[2] It produces antidepressant-like effects in rats.[2] However, captodiamine is unique among antidepressant-like drugs in that it increases brain-derived neurotrophic factor (BDNF) levels in the hypothalamus but not in the frontal cortex or hippocampus.[2] This unique action may be related to its ability to attenuate stress-induced anhedonia and corticotropin-releasing factor (CRF) signaling in the hypothalamus.[2] ...

Vitamin K antagonist
These drugs deplete the active form of the vitamin by inhibiting the enzyme vitamin K epoxide reductase and thus the recycling of the inactive vitamin K epoxide back to the active reduced form of vitamin K. The drugs are structurally similar to vitamin K and act as competitive inhibitors of the enzyme. The term "vitamin K antagonist" is a misnomer, as the drugs do not directly antagonise the action of vitamin K in the pharmacological sense, but rather the recycling of vitamin K. Vitamin K is required for the proper production of certain proteins involved in the blood clotting process. For example, it is needed to carboxylate specific glutamic acid residues on prothrombin. Without these residues carboxylated, the protein will not form the appropriate conformation of thrombin, which is needed to produce the fibrin monomers that are polymerized to form clots.[1] The action of this class of anticoagulants may be reversed by administering vitamin K for the duration of the anticoagulant's residence in ...
Ro4938581

It has good selectivity for the α5 subtype and did not produce convulsant or anxiogenic effects in animal studies, making it a promising potential nootropic.[1][2][3] Ro4938581 and a related derivative basmisanil (RG-1662, RO5186582) have subsequently been investigated for the alleviation of cognitive dysfunction in Down syndrome.[4][5] ...
Phenibut
... also binds to and blocks α2δ subunit-containing VDCCs, similarly to gabapentin and pregabalin, and hence is a gabapentinoid.[9][16] Both (R)-phenibut and (S)-phenibut display this action with similar affinity (Ki = 23 and 39 μM, respectively).[9] Moreover, (R)-phenibut possesses 4-fold greater affinity for this site than for the GABAB receptor (Ki = 92 μM), while (S)-phenibut does not bind significantly to the GABAB receptor (Ki , 1 mM).[9] As such, based on the results of this study, phenibut would appear to have much greater potency in its interactions with α2δ subunit-containing VDCCs than with the GABAB receptor (between 5- to 10-fold).[9] For this reason, the actions of phenibut as a α2δ subunit-containing voltage-gated calcium channel blocker or gabapentinoid may be its true primary mechanism of action, and this may explain the differences between phenibut and its close relative baclofen (which, in contrast, has essentially insignificant activity as a gabapentinoid; Ki = 6 ...

gamma-Aminobutyric acid
Besides the nervous system, GABA is also produced at relatively high levels in the insulin-producing β-cells of the pancreas. The β-cells secrete GABA along with insulin and the GABA binds to GABA receptors on the neighboring islet α-cells and inhibits them from secreting glucagon (which would counteract insulin's effects).[25] GABA can promote the replication and survival of β-cells[26][27][28] and also promote the conversion of α-cells to β-cells, which may lead to new treatments for diabetes.[29] GABA has also been detected in other peripheral tissues including intestines, stomach, Fallopian tubes, uterus, ovaries, testes, kidneys, urinary bladder, the lungs and liver, albeit at much lower levels than in neurons or β-cells. GABAergic mechanisms have been demonstrated in various peripheral tissues and organs, which include the intestines, the stomach, the pancreas, the Fallopian tubes, the uterus, the ovaries, the testes, the kidneys, the urinary bladder, the lungs, and the liver.[30] ...
Bromadiolone
... is a potent anticoagulant rodenticide. It is a second-generation 4-hydroxycoumarin derivative and vitamin K antagonist, often called a "super-warfarin" for its added potency and tendency to accumulate in the liver of the poisoned organism.

The product may be used both indoors and outdoors for rats and mice. It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.[1] ...

Endocrine disruptor assessment list - ECHA
For REACH substances, inclusion in the list means that an informal hazard assessment for endocrine-disrupting properties either is under development or has been completed since the start of the implementation of the SVHC Roadmap in February 2013. For each substance, the table shows the assessing or evaluating Member State (submitter), the outcome and the suggested follow-up for the assessment, and the date of the latest update to the list entry. Other process details and hazard assessment outcome documents are also available and can be accessed through the Details icon. One possible outcome of such an assessment is that a substance is considered not to have ED properties. If the outcome is that the substance is considered to have ED properties, confirmation through the formal risk management and decision-making processes under REACH/BPR is needed before any regulatory action can be taken due to these properties. The intentions of authorities to submit a dossier to the formal REACH and CLP ...
