[Effect of tuftsin and its analog on learning, memory and exploratory behavior in rats].
On Wistar male rats the influence of tetrapeptide tuftsin and its analogue TP-1 (300 mkg/kg, i/p) on animals behaviour was studied. It is shown that administration of peptides increases the rat's exploratory activity. Activating influence of TP-1 was continued for 6 h. Daily multiple administration of tuftsin or TP-1, 15 min prior to the beginning of experiments facilitates the learning and stability of conditioned reaction with food reinforcement. Experimental animals react significantly weaker than the control ones to emotionally negative influence, produced by a sharp reduction of the amount of alimentary reinforcement control.
