[Effects of heptapeptide of the tuftsin group with nootropic components of action and piracetam on formation of escape reaction in normal conditions and in conflict situation].

In this work we have compared the effect of Tuftsin Group synthetic heptapeptide (TP-1) and Piracetam on learning of avoidance response and its restoring after disturbance provoked by unexpected changes of previously established cause-effect relations in experimental environment. We have pointed out that both of the drugs improve learning but the dynamics is different, namely: Piracetam causes the greatest improvement on the 1st day, meanwhile the Heptapeptide--on the 4th day. Both of them preclude from disturbing avoidance response and this protective action of peptide is more effective.
