Objectives: The aim of present study was to evaluate some effects of Crinum zeylanicum (C. zeylanicum) on central nervous system. Materials and Methods: C. zeylanicum methanolic bulb extract (250-1000 mg/kg orally), 2 mg chlorpromazine and 4 mg diazepam /kg body weight intraperitoneally respectively were tested in mice using Irwin test, pentobarbitone-induced sleep test, spontaneous motor acti...

Volatile oil exhibited depressant effect on central nervous system of rats and mice. It blocked CAR in 80% animals and potentiated effects of chlorpromazine hydrochloride on CAR and pentobarbitone induced hypnosis in mice. It exhibited hypothermic and analgesic activities and potentiated morphine induced analgesia considerably. The volatile oil checked tonichind limb extension produced by elect...

Treatment with Spinacia oleracea extract (SO; 400 mg/kg body weight) decreased the locomotor activity, grip strength, increased pentobarbitone induced sleeping time and also markedly altered pentylenetetrazole induced seizure status in Holtzman strain adult male albino rats. SO increased serotonin level and decreased both norepinephrine and dopamine levels in cerebral cortex, cerebellum, caudat...

Sixty-nine patients undergoing regional anaesthesia were premedicated with either lorazepam (1, 2, 3 or 5 mg), diazepam (5 or 10 mg), pentobarbitone (50 mg) or placebo given i.v., on a double-blind, randomized basis. A simple yet rigorous protocol was used to test the effect of these drugs on anterograde recall. Lorazepam 3 and 5 mg was found to affect anterograde recall significantly. None of ...

Albino Wistar rats (either sex, 225 to 250 g) were anesthetized with Sodium pentobarbitone (50 mg/kg, i.p.). Blood pressure was measured with a pressure transducer (T301) on a INCO polygraph through a polypropylene cannula placed in the carotid artery. A polypropylene cannula introduced in the jugulat vein was used for the infusion of drugs. In this study we have tried to ascertain the effect o...

We used constant potential in vivo voltammetry to measure changes in striatal ascorbate in the rat in response to i.p. administration of several non-volatile anaesthetics. Propofol and pentobarbitone, which enhance GABA-mediated neuronal inhibitions, decreased ascorbate current to 27.0 (SEM 7.4) % and 46 (6) % of control, respectively. Chloral hydrate, diazepam alone or with ketamine, and fenta...

THE EFFECT OF HYPOXAEMIA upon the cerebral blood flow (CBF) has been studied in anaesthetised animals, 1-:~ but only intravenous anaesthetic agents, usually pentobarbitone, have been investigated. No studies have been made of the effect of induced hypoxaemia upon Cur in animals under inhalational anaesthesia. The present study was undertaken to determine the effect of hypoxacmia upon CBF at two...

Ischemia/reperfusion (IR) damage is a major cause of dysfunction in transplanted organs. The objective of the present study was to correlate in vivo measurements of respiratory chain (RC) function with histological and physiological parameters. Non-invasive in situ (surface fluorescence) measurements of mitochondrial NADH and near infrared spectroscopic measurements of cyt aa3 were made in unst...
