scopolamine/fever

The organophosphate pesticide (OP) chlorpyrifos leads to an acute period of hypothermia followed by a delayed fever in the rat. Methyl scopolamine, a peripheral muscarinic antagonist, is thought to have little effect on body temperature of the rat because it does not cross the blood brain barrier.

OBJECTIVE To determine the effect of soman on stress induced hyperthermia and the influence of central and peripheral cholinergic antagonists. METHODS Effects of subcutaneous injection of soman, scopolamine, methylscopolamine and pyridostigmine on stress-induced hyperthermia were observed in rats by

Wistar rats from one supplier have been shown to exhibit the atypical body temperature responses to morphine. In contrast to commonly used rats, in which morphine induced dose-dependent changes in body temperature, the initial administration of morphine (5, 10, 20, and 40 mg/kg, s.c.) to rats of

Morphine action at opiate receptors in the ventral tegmental area (VTA) of the rat brain has been implicated in the production of increased locomotor activity and in morphine's rewarding properties. In the present experiments, bilateral administration of morphine (18 micrograms tapped into the tips

Exposure to an open field is psychologically stressful and leads to an elevation in core temperature (T(c)). Methyl scopolamine (MS), a muscarinic antagonist, and pyridostigmine (PYR), a carbamate that inhibits acetylcholinesterase, do not cross the blood-brain barrier and have little effect on T(c)

Bole of adrenals in morphine-induced hyperthermia was studied in normal, neurotransmitter antagonist-pretreated, chemical-sympathectomized, adrenalectomized or adrenal-demedullated rats. In restrained female rats, 5 mg/kg morphine produced hyperthermia whereas 20 mg/kg and 40 mg/kg produced

The present experiments were performed to investigate the effects of dopamine D1 receptor agonists given alone or in combination with dopamine D2 receptor agonists on body temperature in rats. The selective dopamine D1 receptor agonist, 1-phenyl-2,3,4,5-tetrahydro-(1H)-3-benzazepine-7,8-diol

BACKGROUND E. coccinae (SIMS) G. (Asteraceae) is an annual plant commonly found throughout the plain of the Central Africa and widely used in Cameroonian folk medicine for the treatment of fever and convulsions in children. We previously reported that the methanolic extract of this plant improved

Prunella vulgaris L. is as a major plant in the Chinese traditional functional beverage Guangdong herbal tea for the treatment of fevers, diarrhea, and sore mouth. In this study, ethyl acetate parts of aqueous extracts from P. vulgaris L. (EtOAc-APV) were found to demonstrate potent

The central anticholinergic syndrome (CAS) includes central signs (somnolence, confusion, amnesia, agitation, hallucinations, dysarthria, ataxia, delirium, stupor, coma) and peripheral signs (dry mouth, dry skin, tachycardia, visual disturbances and difficulty in micturition). It occurs when central

(1) Renal colic is an acute syndrome involving unilateral flank pain, linked to an obstruction in the upper urinary tract. The pain is often intense. After having considered other diagnoses and checked for signs of complication (fever, oligoanuria), the first step is to control the pain; (2) Which

Datura stramonium (DS) is a widespread annual plant, containing atropine, hyoscyamine, and scopolamine, which can produce poisoning with a severe anticholinergic syndrome. Teenagers ingest the roots, seeds or the entire plant to obtain its hallucinogenic and euphoric effects. We presented the case

Alzheimer's disease (AD) is a neurodegenerative disease and a common cause of dementia, manifesting as progressive memory loss and cognitive decline. Moscatilin, which reportedly reduces fever and is anti-inflammatory, is the bibenzyl extract from Dendrobium loddigesii. This study aimed to

We attempted to determine if the cholinomimetic activity of the psychotropic drug minaprine was related to the amelioration of the delayed neuronal death induced by cerebral ischemia in Mongolian gerbils. Minaprine improved the passive avoidance deficit induced by cerebral ischemia, and the
