Abstract

The effects of the synthetic dipeptide, L-pyroglutamyl-D-alaninamide (LPDA) were studied in the experiments on offspring of alcoholized during the pregnancy (5 g/kg/day) females. This dipeptide, which revealed the nootropic activity in previous experiments, was injected to the pups in dose of 1 mg/kg from 8 to 19 days of life. LPDA was shown to prevent the delayed disturbances of learning in passive avoidance test, of extrapolatory behaviour in escape test, to attenuate the emotional hyperreactivity. LPDA normalized EEG power spectrum, decreased interhemispheric asymmetry. This substance attenuated the disbalance evoked by prenatal alcoholization.
