Prolonged effect of tetrapeptidamide on metabolism of neuromediators in cortex-subcortex structures of brain

The research work demonstrated prolonged effect of tetrapeptidamide (TPA) on metabolism of neurotransmitters according to the enzymatic activity of dopamine and serotonin synthesis and utilization of monoaminooxidase (MAO A and B) in the cortex and in caudate nucleus in brain of rats and rabbits
