It has been shown in experiments on albino rats that acute myocardial ischemia (AMI) produces a noticeable increase in excretion of adrenaline, noradrenaline, DOPA and dopamine with urine. Intraperitoneal injection of leu-enkephalin analogs (D-Ala2-Leu5-Arg6 and D-Ala2-D-Leu5-D-Arg6) to rats with AMI was accompanied by a noticeable prevention of activation of the sympathoadrenal system.
