Popis: Increases are found in the lactate concentration and lactate dehydrogenase activity in the myocardium and hexokinase and glucose-6-phosphate dehydrogenase activity in the myocardium and liver 24 h after intraperitoneal injection of large doses of noradrenalin, after exhaustion of its reserves in the myocardial and hepatic tissues of rats. Activity of glucokinase, which phosphorylates glucose when present in high concentrations in the medium, is reduced. Changes in enzyme activity thus observed are similar to those developing in degeneration of denervated tissues, with a sharply reduced catecholamine content, and they confirm the important role of the sympathetic nervous system and its mediators in the mechanism for controlling enzymic processes of energy metabolism in the myocardium and liver.
