[Enzymes of tissue respiration and oxidative phosphorylation in the myocardium after neurogenic damage to it].

Three-hour electrical stimulation of the aortic arch in the rabbit myocardium is followed by a marked increase of the succinate dehydrogenase activity, by a sharp fall of the cytochrome oxidase activity and by uncoupling of the oxidation and phosphorylation processes. It is suggested that neurogenic myocardial damage is accompanied by discoordination in the energy processes regulation with uncoupling of the oxidative phosphorylation and by a decrease of the macroergic compounds synthesis.
