[Monoamine oxidase activity in autonomic ganglia of rabbits with differing resistance of cardiovascular functions to emotional stress].

The Glenner method was used to study monoamine oxidase (MAO) activity in the neurons of superior cervical, stellatum and nodosum ganglia of rabbits with different resistance of cardiovascular functions to emotional stress. Acute experimental emotional stress was induced by electrical stimulation of the hypothalamus and skin in immobilized adult male Chinchilla rabbits. MAO activity was found to be changed in the neurons of sympathetic ganglia (cervical and stellatum) under acute experimental emotional stress. In stress-resistant rabbits, MAO activity increased, while in stress-predisposed animals, it declined. MAO activity in the nodose ganglion of the vagus nerve remained unchanged under acute experimental emotional stress.
