【摘要】为了探讨补体C5在心肌梗死死后诊断的特异性，应用免疫组织化学和图像分析技术,对正常心脏、心肌梗死及其它非梗死性的引起直接或间接心脏损害的情况如心肌炎、窒息、电击死、出血性休克、心挫伤、有机磷中毒等心肌细胞内C5的变化进行研究。结果发现：C5仅在心肌梗死与心肌炎病例出现阳性反应，其阳性反应面积同正常对照组存在显著性差异，在窒息、电击死、出血性休克、心挫伤、有机磷中毒等病例未见明显阳性反应。因此C5作为心肌梗死死后诊断指标仅受心肌炎的影响，对诊断心肌梗死具有较好的特异性。%In order to explore the specificity of complement C5 in the postmortem diagnosis of myocardial infarction, changes of C5 staining in normal, infarcted and other non-infarcted myocardia with direct or indirect
myocardial
injuries
(myocarditis, shock,
mechanical asphyxia,
contusion
and
electrocution, hemorrhagic cardiac
organophosphate poisoning) were studied with immunohistochemistry and image analysis. The results showed that positive C5 staining could be observed in groups of myocardial infarction and myocarditis, but not in groups of mechanical asphyxia, electrocution, hemorrhagic shock, cardiac contusion, and organophosphate poisoning. It is indicated that positive reaction of C5 could only be affected by myocarditis, which
