[Adrenergic innervation of the cerebral arteries following changes in the activity of cholinergic and monoaminergic brain systems].
Bipolar electrical nerve stimulation decreased the adrenergic innervation density and the catecholamine content in the rat isolated caudal artery. Changes in cholinesterase activity and catecholamine content in histochemically active nerves following administration of cholinesterase (AChE) inhibiting agent phosphacol, seem to reflect compensatory responses to increasing dilatory cholinergic vasomotor effects under conditions of the AChE activity. Adrenergic innervation of cerebral arteries was also studied after a 1-hr daily hypoxic sessions. These decreased the catecholamines content as compared to the control.
