Abstract: | The effects of chronic treatment (30 days) with the 5-HT1A receptor partial agonist buspirone (0.05, 1 and 10 mg/kg i.p.) on the behaviour of C57BL/6J female mice exposed to long-lasting psychoemotional influence were studied. The influence involved forced living of each female with an aggressive male separated with a perforated transparent partition in the same cage and daily female's presence during 10-min intermale confrontations behind a partition caused by introducing of another male to the aggressive male. Chronic buspirone injection (in all used doses) did not affect the behaviour of females estimated in the "partitions" and "open field" tests at the end of the drug treatment. The anxiolytic effect of buspirone only at the dose of 1 mg/kg on the female's plus-maze behaviour was revealed. In the Porsolt, test buspirone in the dose of 1 mg/kg caused a slight increase in the duration of immobility indicating a slight pro-depressive effect. Thus, chronic buspirone treatment of females exposed to the long-lasting psychoemotional impact has a different effect on their behaviour depending on the dose and test conditions. |
