Immunohistochemical study of C5 complement in experimental early myocardial ischemia / 中国法医学杂志

Experimental acute myocardial ischemia model of rat was established, and the changes of C5 complement in the ischemic myocardia were studied with immunohistochemistry and image analysis technique. The results showed that the positive reaction of C5 could be observed in ischemic myocardia at 15 min after ischemia, and the positive reaction area increased along with the prolongation of the ischemic period. It is concluded that the positive reaction of C5 in cardiomyocytes is a quite sensitive marker of early myocardial ischaemia.The immunohistochemical detection of C5 in cardiomyocytes will be a meaningful tool for the postmortem diagnosis of early myocardial ischaemia.
