we studied the effect of the selective alha-2 adrenoceptor blocker idazoxan and precursor serotonin (5-htp) on anxiety-related behavior in rats. the conflict drinking test, and evaluator plus-maze were used as model. idazoxan (2 mg/kg) showed an anticonflict effect, having doses dependently increased the number of punished lickes. 5-htp showed that anxiolytic-like effect in both models. this dr...

Panax ginseng C.A. MEYER (Araliaceae), which contains ginsenosides as its main components, has been shown to have various biological effects, including anti-inflammatory, anxiolytic, anti-stress, and anti-tumor effects. Orally administered ginsenoside Rb1 and Re are metabolized to 20(S)-protopanaxadiol (PPD) and compound K via ginsenoside Rd and 20(S)-protopanaxatriol (PPT) and ginsenoside Rh1 ...

methanol extract of dried leaves of momordica charantia linn ( cucurbitaceae ) was investigated for anxiolytic, antidepressant and anti-inflammatory activities in animal models. anxiolytic activity of methanol extract of dried leaves of momordica charantia linn was tested by elevated plus maze test and the results showed a significant anxiolytic effect comparable, with diazepam in all the teste...

The study attempts to evaluate whether neuropeptide Y (NPY) and corticotropin-releasing factor (CRF) are involved in anxiogenic and anxiolytic reactions induced by NMDA receptor ligands. The animals were given MK-801 (1 mg/kg, ip), a non-competitive NMDA-receptor antagonist, which acts as anxiolytic agent, or NMDA (15 mg/kg, ip), which has an anxiogenic effect. The anxiogenic or anxiolytic acti...

background and objective: the medicinal plant origanum vulgare. subsp. vulgare in the lamiaceae family has been widely used by iranian people for the treatment of respiratory, gastrointestinal and neurologic disorders. the present study was carried out to evaluate possible anxiolytic effects of aqueous extract of o. vulgare leaves and the flowering branches in rats.materials and methods: anxiol...

Despite being potent anxiolytic agents, benzodiazepines (BDZ) sometimes show reduced therapeutic efficacy in stressed rodents. However, the effectiveness of norepinephrine reuptake inhibitors (NRI) and serotonin-norepinephrine reuptake inhibitors (SNRI) or other anxiolytic interventions, e.g., exercise, remained elusive. Here, we demonstrated that male rats subjected to restraint stress for 4 w...

BACKGROUND The placebo effect in relieving negative emotion arousal is poorly understood. AIMS We examined whether placebo expectation established with noise stimuli could have a transferable anxiolytic effect on negative emotion arousal. METHODS In Experiment 1, noise intensity was surreptitiously lowered during placebo condition in the preconditioning phase to reinforce placebo expectatio...

INTRODUCTION Anxiolytic drugs are amongst the most frequently prescribed drugs. Available anxiolytic agents are associated with several limitations. Several indigenous drugs are being evaluated but none has been proved to be effective. OBJECTIVES Aim of the present study is to evaluate the anxiolytic effect of Tensarin. MATERIAL AND METHOD The behavioural tests were conducted with single do...

Behavioral studies have suggested an involvement of the glutamate pathway in the mechanism of action of anxiolytic drugs, including the NMDA receptor complex. It was shown that magnesium, an NMDA receptor inhibitor, exhibited anxiolytic-like activity in the elevated plus-maze test in mice. The purpose of the present study was to examine interaction between magnesium and benzodiazepine/GABA(A) r...

putative activity of hydroalcoholic and aqueous infusion extracts of echium amoenum l. was investigated in mice using the rotarod model of motor coordination and the elevated plus maze model of anxiety. the extracts were administered intraperitonealy (i.p.) once, one hour before performing the tests. preliminary phytochemical study of the plant, with standard procedures, showed that it contains...
