the purpose of the present investigation was to determine the normal perioperative variations in the serum concentration of creatine phosphokinase ( cpk ) and its isoenzymes mm , mb , and bb , and of lactic dehydrogenase ( ldh ) and its isoenzymes ldh1 to ldh5 to distinguish operation-induced changes in these enzymes from those due to acute myocardial infarction or malignant hyperthermia .
