The objective of this study was to identify the pharmacological effects of bee venom and
its major component, melittin, on the nervous system of mice. For the pharmacological
analysis, mice were treated once with saline, 0.1 or 1.2 mg/kg of bee venom and 0.1 mg/kg
of melittin, subcutaneously, 30 min before being submitted to behavioral tests: locomotor
activity and grooming (open-field), catalepsy, anxiety (elevated plus-maze), depression
(forced swimming test) and apomorphine-induced stereotypy. Haloperidol, imipramine and
diazepam were administered alone (positive control) or as a pre-treatment (haloperidol). The
bee venom reduced motor activity and promoted cataleptic effect, in a similar manner to
haloperidol. These effects were decreased by the pretreatment with haloperidol. Both melittin
and bee venom decreased the apomorphine-induced stereotypies. The data indicated the
antipsychotic activity of bee venom and melittin in a murine model.
