[Pharmacoethological analysis of the effects of thyroliberin and melanostatin in a model of anxious-defensive behavior in mice]. / Farmakoétologicheskii analiz éffektov tiroliberina i melanostatina na modeli trevozhno-zashchitnogo povedeniia myshei.

Psychotropic properties of thyroliberin and melanostatin were studied on the model of timid-defensive behaviour of mice. Oligopeptides increased defensive behaviour and timidity, and decreased intraspecies sociability. GABA deficiency and dopaminergic system blockade increased timid-defensive behaviour of mice. Mobilizing activity of peptides on the agonistic behaviour (aggression and defense) may be explained by their anxiogenic properties.
