Oxydemeton-methyl, an organophosphate insecticide and acaricide produced decrease in the exploratory behaviour and prolongation of barbitone sodium-induced hypnosis after intermittent aerosol spray inhalational exposure for 1 h in rats compared to the saline control group. Further, CD50 +/- S.E.M. value for pentylenetetrazole (PTZ) and CI50 +/- S.E.M. value for electroshock (i.e. the dose of PTZ and intensity of electroshock producing positive seizure response in 50% of rats) were significantly decreased by acute exposure to oxydemeton-methyl compared to that of saline control group.

Oxydemeton-methyl, an organophosphate insecticide and acaricide produced decrease in the exploratory behaviour and prolongation of barbitone sodium induced hypnosis in rats after intermittent aerosol spray inhalational exposure, for 1/2 hour daily for 7 consecutive days, compared to the saline control group. Further, ED50 +/- SEM value for haloperidol induced catalepsy, CD50 +/- SEM value for pentylenetetrazole induced seizure and CI50 +/- SEM value for electroshock (i.e.

Goodyerin is a flavonol glycoside isolated from the whole plants of Goodyera schlechtendaliana which has been used as a substitute for the crude drug, Anoectochilus formosanus. The pharmacological properties of goodyerin were assayed for effects on spontaneous locomotor activity, on pentobarbital-induced hypnosis, and on anticonvulsant activity against picrotoxin-induced seizures in rodents. Goodyerin exhibited a significant and dose-dependent sedative and anticonvulsant effect.

This study was undertaken to evaluate the psychopharmacological effects in mice of the hydroethanolic extract (HE), aqueous, hexane and ethyl acetate (EA) fractions, and 6-methoxy-7-prenyloxycoumarin, three dihydrostyryl-2-pyrones and three styryl-2-pyrones isolated from Polygala sabulosa (Polygalaceae), a folk medicine used as a topical anesthetic. In the elevated plus-maze test (EPM), the HE of P.

Bacopa monnieri (BM) an herb, found throughout the Indian subcontinent in wet, damp and marshy areas is used in Ayurvedic system of medicine for improving intellect/memory, treatment of anxiety and neuropharmacological disorders. Although extensively given to children as a memory enhancer, no data exists on its ability to modulate neuronal oxidative stress in prepubertal animal models.

The physiological and pharmacological properties of taurine-induced responses were investigated in dopaminergic (DA) neurones from the ventral tegmental area (VTA) of young rats aged 1-13 postnatal days, either in acute brain slices or acutely dissociated neurones. When whole-cell responses were recorded from current-clamped neurones using the gramicidin-perforated technique, the application of taurine (0.01-30 mm) accelerated firings and induced membrane depolarization.

The effects of Kamikihi-To (KMK), a traditional Chinese medicine, on behavioral changes induced by methyl-beta-carboline-3-carboxylate (beta-CCM) were evaluated in mice and rats. Beta-CCM, an anxiogenic benzodiazepine receptor inverse agonist (3.0 mg/kg, i.v. administered 1 min before the test), decreased the locomotor activity of mice in a novel environment. Furthermore, beta-CCM (0.1 mg/kg, i.v. administered 10 min before the test) facilitated the suppression of drinking behavior induced by punishment in the water lick conflict test in rats. KMK (1.0 and 2.0 g/kg, p.o.

BACKGROUND: The afferent projections from the auricular branch of the vagus nerve (ABVN) to the nucleus tractus solitaries (NTS) have been proposed as the anatomical basis for the increased parasympathetic tone seen in auriculo-vagal reflexes. As the afferent center of the vagus nerve, the NTS has been considered to play roles in the anticonvulsant effect of cervical vagus nerve stimulation (VNS).
