title: Kallikrein effect on the acquisition and extinction of conditioned reflexes in rats.
abstract: The effect of kallikrein was studied on the acquisition and extinction of conditioned reactions in rats. It was demonstrated that kallikrein in doses of 50 and 100 mu/kg i.p. accelerated the process of learning in these animals. The observed effect might be connected with a rise in the activity of kininogenic enzymes in the central nervous system.
