[The anxiogenic activity of phenylethylamine in the social isolation test on mice]

One-day isolation of male albino mice of SHR strain significantly increased the level of social behaviour measured by the number and total duration of active contacts (sniffings). A putative endogenous anxiogen beta-phenylethylamine (5-12.5 mg/kg) inhibited the communication like human anxiogens corazole (10 mg/kg) and caffeine (200 mg/kg). Diazepam (1 mg/kg) prevented the action of phenylethylamine, phenibut (10-50 mg/kg) exerted no effect on it. The social isolation test during studying anxiogens and anxiolytics can be performed on mice as previously on rats.
