Popis: | Imidazobenzodiazepine (Ro 15-1788, 5 mg/kg) similarly to a lose dose of apomorphine (0.1 mg/kg) decreased the intensity of footshock aggression in male rats. Ro 15-1788 significantly potentiated the antiaggressive action of apomorphine. Pirenperone (0.01 mg/kg) potentiated the effect of both drugs, whereas haloperidol (0.01 mg/kg) had an opposite action. After long-term treatment with apomorphine and Ro 15-1788 the tolerance to their antiaggressive action developed. This change was in agreement with increased serotonin metabolism in the forebrain. Unlike the action on aggressive behavior, Ro 15-1788 similarly to haloperidol (0.05 mg/kg) decreased the motor depressant effect of apomorphine (0.01 mg/kg) in mice. This effect correlated with the lowered serotonin metabolism after Ro 15-1788 administration. Unlike apomorphine, Ro 15-1788 reversed catalepsy induced by haloperidol (0.25 mg/kg). Administration of pirenperone (0.03 mg/kg) and destruction of serotoninergic terminals by p-chloroamphetamine (2 X 15 mg/kg) significantly potentiated the sedative action of apomorphine. It appears that different action of Ro 15-1788 on behavioral effects of apomorphine is related to different influence of Ro-1788 on serotoninergic processes in the striatum and limbic structures. |
