[Effect of biogenic amines on phosphorolysis and gamma-amylolysis of glycogen in the cardiac muscle of rats under anesthesia].

Adrenaline, poradrenaline, serotonin, triptamine and 3-hydroxytyramine activated glycogen phosphorolysis in heart of nonanesthetized rats due to increase in the phosphorylase A activity. Anesthesia with nembutal and ether prevented the stimulating effect of biogenic amines (excluding serotonin) on phosphorolysis. Adrenaline, administered into animals anesthetized with nembutal, inhibited the glycogen phosphorolysis. Noradrenaline caused a decrease in gamma-amylolysis of glycogen in anesthetized and untreated rats. The inhibitory effect of adrenaline on glycogen gamma-amylolysis occurred in rat heart muscle only under the conditions of anesthesia.
