We studied variations in the activity of total creatine kinase (CK; EC 2.7.3.2) and of CK-B in maternal and cord-blood samples, comparing data obtained for vaginal and cesarean births. CK-B activity was determined with an immunoinhibition assay. In all cases, there was a significant postpartum increase in total CK and in CK-B activity in maternal sera, whereas cord-blood samples showed no significant differences between activities in arterial and venous blood for either vaginal or cesarean births. Statistically significant differences were found in CK-B activity, but not in total CK, between cord-blood samples from vaginal births and those from cesareans.
我们研究了母体和脐带血样本中总肌酸激酶（CK；EC 2.7.3.2）及CK-B活性的变化，并比较了经阴道分娩和剖宫产所获数据。CK-B活性采用免疫抑制法测定。在所有情况下，母体血清中的总CK及CK-B活性在产后均显著升高，而无论是经阴道分娩还是剖宫产，脐带血样本的动脉血和静脉血活性之间均无显著差异。经阴道分娩和剖宫产的脐带血样本在CK-B活性上存在统计学显著差异，但在总CK上无差异。
