title: [Effect of the D1-receptor antagonist SCH-23390 on the individual and aggressive behavior in male mice with various aggression experience].
abstract: It has been shown that dopaminergic systems are involved in mechanisms of aggressive behavior. Effects of SCH 23390 (dopamine Di receptors antagonist. 0-1 mg/kg, i/p, 30 min) on aggressive and individual behaviors were studied in male C57BL/6J mice with different experience of aggression. SCH 23390 reduced aggressive attacks in animals without preliminary experience of aggression. However total time of hostile behavior (sum of the total time of attacks, aggressive grooming and diggings) didn't changed. No significant effects on behaviors were found in mice with long (20 days) repeated experience of aggression. It was supposed that long aggressive experience produces pharmacological desensitization of Di receptors as a result of enhanced dopaminergic activity shown earlier in aggressive animals.
