    Abstract:
    On the basis of the idea of the important role of neurotransmitter systems in realization of neuropeptide effects, the participation was studied of the monoaminergic systems in the mechanisms of the ACTH analogue influence on the processes of learning and memory in control animals and animals with a changed functional state of the monoaminergic systems. In parallel the influence was studied of the ACTH analogue on the content of the endogenic monoamines in various brain structures of rats. It has been shown that administration of the ACTH analogue in a dose of 10 mcg affects the elaboration and preservation of conditioned reflexes (CRs) of passive avoidance, CRs of two-side avoidance and labyrinth CRs only in conditions of changed functional state of the monoaminergic systems. Amnesia, usually elicited by 5-oxytryptophane and disulfiram is prevented by administration of the ACTH analogue. Administration of the ACTH analogue is accompanied by the intensification of serotonine metabolism in the midbrain and medulla and by an increase of noradrenaline content in the hypothlamus.
