[Disorders in the adrenergic innervation of the stomachs of rats with stable regulation of cardiovascular function in the presence of emotional stress].
Changes of arterial pressure and of the frequency of cardiac contractions were analyzed in Wistar rats under acute immobilization stress; stability of the cardiovascular functions under emotional stress was revealed. An increased sensitivity of the adrenergic component of the sympathetic and parasympathetic innervation of the stomach that caused the development of its dystrophic processes was observed. Emotional stress proved to be accompanied by phasic dynamics of disorders in the adrenergic innervation: mobilization in the adrenergic innervation was followed by its exhaustion.
