The statistical analysis of catalepsy revealed a significant difference between treatments (F5-59 = 8.086, p < 0.0001; ANOVA followed by Tukey post-test ), as illustrated in Table 1. The groups treated with 0.1 mg/kg of BV and melittin (0.1 mg/kg) recorded lesser time spent on the bar. In contrast, the administration of 1.2 mg/kg of BV induced cataleptic activity, an effect similar to that observed with haloperidol treatment. When the treatments were combined, it was observed that a lower dose of BV did not modify the action of haloperidol, while the administration of 1.2 mg/kg reversed the observed effects. The animals that received saline solution did not remain on the bar and thus were not subject to statistical analysis.
