title: [Change in the activity of creatine kinase and its MB isoenzyme as affected by partial and complete occlusion of the coronary artery in rats].
abstract: A model of different degree left coronary artery (LCA) occlusion in rats has been developed. The activity of creatine kinase and its cardiospecific MB isoenzyme was determined both in the cardiac muscle and blood plasma of 62 animals at different time after complete or partial LCA occlusion. A direct dependence of the decrease in the enzyme activity in the heart and hyperfermentemia on the degree of LCA occlusion has been established. It is concluded that the model of LCA occlusion in rats could be useful for the study of different forms and stages of myocardial ischemia.
