OBJECTIVE It has been shown that neurosteroids can either block or stimulate the development of chronic and rapid tolerance to the incoordination and hypothermia caused by ethanol consumption. The aim of the present study was to investigate the influence of isopregnanolone on the development of rapid tolerance to the anxiolytic effect of ethanol in mice. METHOD Male Swiss mice were pretreated...

introduction: dracocephalum polychaetum bornum is exclusively found in a limited geographical area in the kerman province it is used by the local people for treatment of abdominal pain, meteorism and musculoskeletal pain. no study has been performed on the effects of d. polychaetum bornum, so the aim of this work was to assess the role of the extract and essential oil of this plant on pain and ...

The aim of the present study was to examine a potential anxiolytic- and antidepressant-like action of (+)-7-hydroxy-2-(di-n-propylamino)tetralin hydrobromide (7-OH-DPAT), a preferential dopamine D(3) receptor agonist, and N-{4-[4-(2-methoxyphenyl)-1-piperazinyl]butyl}-2-naphthylcarboxamide (BP 897), a partial dopamine D(3) receptor agonist, in male Wistar rats. Diazepam or imipramine were used ...

conclusions acute and chronic administration of ellagic acid had anxiolytic property. also, the most effective dose of ellagic acid was 30 mg/kg. pretreatment with flumazenil reversed the beneficial effect of ellagic acid and diazepam on anxiety. it is likely that the anxiolytic effect of ellagic acid is largely mediated by activation of gabaa receptor. results acute and chronic application of ...

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 t...

UNLABELLED INTRODUSTION: Sibutramine has been described as a drug recommended for treatment of obesity, since it has the ability to inhibit the reuptake of serotonin and noradrenaline in the central nervous system, thereby increasing energy expenditure. OBJECTIVE Investigate the anxiogenic and anxiolytic effects of acute and chronic treatment with sibutramine in rats submitted to the task of ...

BACKGROUND Besides the well-known effects of ghrelin on adiposity and food intake regulation, the ghrelin system has been shown to regulate aspects of behavior including anxiety and stress. However, the effect of virus-mediated overexpression of the ghrelin receptor in the amygdala has not previously been addressed directly. METHODS First, we examined the acute effect of peripheral ghrelin ad...

Substances acting as agonists of group III mGlu receptors were shown to induce an antianxiety-like effect after intrahippocampal administration to rats. The purpose of the present study was to establish whether the selective mGlu8 receptor agonist (S)-3,4-dicarboxyphenylglycine ((S)-3,4-DCPG) induced an anxiolytic-like effect after injection into the basolateral amygdala nuclei or the CA1 regio...
