[Cyclic AMP content of autonomic ganglia as affected by catecholamines].

The relative content of cAMP was measured in the rat ganglion nodosum, lumbar ganglia of the sympathetic trunk, the main pelvic ganglion and intramural ganglia of the heart. It was observed that the basal level of cAMP in the cardiac ganglia was lower than in other ganglia. The process of stimulation of the cAMP content by noradrenaline was most pronounced in the main pelvic and lumbar ganglia, that by dopamine in the cardiac ganglia. The catecholamines failed to alter the cAMP content in the ganglion nodosum.
