在心脏中,肌酸磷酸激酶(CPK)仅存在于心肌组织中,而不存在于结缔组织或其他非心脏组织中,因此较其他酶测定更能反映心肌损害情况。清醒狗于阻塞冠状动脉后,释放至血循环中的 CPK(CPK_R)和从心肌消耗的 CPK(CPK_D)比值柑当恒定(平均为0.15±0.016)。CPK 可能自心肌以外的肌
In the heart, creatine phosphokinase (CPK) is present only in the myocardium but not in the connective tissue or other non-cardiac tissues and therefore reflects myocardial damage better than other enzyme assays. After Awake Dog occludes the coronary artery, the ratio of CPK (CPK_R) released from the circulation to CPK consumed from the myocardium is constant (average of 0.15 ± 0.016). CPK may be from muscles other than the myocardium
