title: Combined administration of NAN-190 and 17beta-estradiol abolishes the amnesic effect of scopolamine in middle-aged ovariectomized rats.
abstract: Chronic combined administration of 5-HT1A receptor antagonist NAN-190 and 17beta-estradiol improved conditioned passive avoidance performance in middle-aged ovariectomized rats with scopolamine-induced amnesia. Our results suggest that the ovarian hormonal, cholinergic, and serotoninergic systems play a role in age-related cognitive disturbances under conditions of hypoestrogenic syndrome.
