Abstract:
We studied the neurotropic effects of ACTH(4-10) analog semax against the background of dopaminergic receptors blockade with haloperidol. Intranasal administration of semax (0.05, 0.2, and 0.6 mg/kg) produced virtually no effect on disturbances of orientation and exploratory reactions and motor activity caused by intraperitoneal injection of 0.2 mg/kg haloperidol. By contrast, preliminary administration of 0.05 mg/kg semax prevented haloperidol-induced disturbances in active avoidance conditioning.
