    Abstract:
    We investigated the effect of a single 2 micrograms dose of a vasopressin (AVP) analog, [d(CH2)(1)5,Tyr(Me)2,delta 3Pro7]AVP on processes of retrieval, consolidation and acquisition of conditioned reflexes in rats with experimentally induced amnesia. The investigated amnesia models were: long term ethanol intoxication, electroconvulsive shocks (ECS), and hypoxia. They all profoundly impaired the learning and memory processes in all tests used. The AVP analog-[d(CH2)(1)5,Tyr(Me)2,delta 3Pro7]AVP facilitated retrieval of passive avoidance in all amnesia models. It improved consolidation of active avoidance of rats previously treated with alcohol, but did not affect the acquisition of active avoidance. [d(CH2)(1)5,Tyr(Me)2,delta 3Pro7]AVP lack antidiuretic properties.
