objective: insomnia is accompanied by several health complications and the currently used soporific drugs can induce several side effects such as psychomotor impairment, amnesia, and tolerance. the present study was planned to investigate the sleep prolonging effect of pinus eldarica. materials and methods: hydroalcoholic extract (hae) of p. eldarica, its water fraction (wf), ethyl acetate frac...

In this present study Indian traditional Ayurvedic herbal formulation Amritaristo has been studied to assess the general pharmacological effect on mice. The drug showed no significant activity on the neuropharmacological test models experimented. The increased pentobarbital sleeping time was considered related with hepatic metabolism of pentobarbital. The formulation exhibited a nonsignificant ...

In previous studies in vitro we showed that the quinone fraction (QF) from the heartwood of Auxemma oncocalyx TAUB. presented antiplatelet and antioxidant activities. In the present work, the QF antioxidant property was evaluated in models of CCl(4)-induced hepatotoxicity in rats, and prolongation of pentobarbital-induced sleeping time in mice. Our results showed that levels of plasma glutamate...

In a five-center study, 73 patients with severe head injury and elevated intracranial pressure (ICP) were randomly assigned to receive either a regimen that included high-dose pentobarbital or one that was otherwise similar but did not include pentobarbital. The results indicated a 2:1 benefit for those treated with the drug with regard to ICP control. When patients were stratified by prerandom...

Rosa damascena has been found to act on central nervous system including the brain. Several studies confirm that R. damascena inhibits the activity of the hypothalamus and pituitary systems in rat and can suppress the central nervous system. In traditional medicine hypnotic effect of Rose is also suggested. In this study, the hypnotic effect of the ethanol crude extract of R. damascena and its ...

A sensitive assay for the determination of four different barbiturates: butabarbital, cyclobarbital, pentobarbital and secobarbital is described. The barbiturates are determined quantitatively by gas chromatography/mass spectrometry (GC/MS) as their dimethylated derivatives. The sensitivity of this simple procedure is limited to 10 x 10(-6) g/l for cyclo- and secobarbital and 1 x 10(-6) g/l for...

A new method of determining the rate of glucose utilization in brain regions of individual rats has been used to measure the dose dependency of the reduction of the metabolic activity of the cerebral cortex by pentobarbital. Cerebral cortical glucose utilization is depressed to a basal level of 44% of the control rate when cerebral pentobarbital levels exceed 50 microgram per g of tissue. The m...

Taurine was extracted from Pegasus laternarius Cuvier to study its effects on learning and memory in mice. Mice were treated with different doses of taurine (10 mg/kg, 20 mg/kg, 40 mg/kg). The mice were treated with various chemical agents (pentobarbital, cycloheximide, sodium nitrite, alcohol) to disrupt the normal memory process. We measured the effect of taurine on step-down latency (SDL) an...

Delirium is a common syndrome present at the end of life and causes significant distress for patients and families. Sleep disruption is a common precipitating factor for delirium and restoration of sleep may be instrumental in attenuating symptoms. In this cases series, we present three patients who were unresponsive to escalating doses of standard delirium medications, but whose delirium resol...

In a canine stroke model, dose dependent protection by postocclusion pentobarbital was suggested from 10--40 mg/kg. In 28 dogs investigated (10 from a previous study) a distinct, significant reduction in right cerebral hemisphere infarction occurred in animals given 15--20 mg/kg pentobarbital intramuscularly 1 hour postocclusion. Increased dosages did not alter statistically the infarct size an...
