Abstract

The present work was aimed at a comparative investigation of the effects of chronic administration of the 5-HT1A receptor agonist 8-OH-DPAT (0.05 mg/kg, s.c.) and 5-HT1A receptors antagonist NAN-190 (0.1 mg/kg, i.p.) for 14 days on anxiety-like behavior in prenatally stressed female with the experimental estrogen deficiency induced by ovariectomy. Chronic administration of 8-OH-DPAT to ovariectomized prenatally stressed females resulted in an anxiolytic effect and led to correction of the impaired levels of follitropine and estradiol. Administration of NAN-190 to ovariectomized prenatally stressed females increased the level of anxiety and more profoundly destroyed a relation between the levels of gonadotropic hormones and peripheral gonadal hormones.
