| 摘 要： | 建立狗急性心肌缺血模型,应用免疫组织化学和图像分析技术,对用纤维连接蛋白诊断心肌梗死的稳定性进行研究。心肌缺血组织随死后放置时间延长,纤维连接蛋白阳性反应面积逐渐减少,但放置4周仍呈阳性反应;而正常心肌组织放置不同时间,均未见阳性反应。纤维连接蛋白在心肌梗死死后诊断上具有很好的稳定性,在法医学实践中具有重要实用价值。

| Abstract: | Experimental acute myocardial ischemia model of dog was established, and the postmortem stability of fibronectin for the diagnosis of mycardial infarction was studied with immunohistochemistry and image analysis technique. The results showed that the positive reaction areas of fibronectin in ischemic myocardial tissues decreased along with the prolongation of postmortem interval, but positive reaction of fibronectin could still be found in ischemic myocardia kept for 4 weeks postmortem. No positive reaction for fibronectin could be found in normal myocardia when kept for different times. So fibronectin is a quite stable marker for the postmortem diagnosis of myocardial infarction, and is of practical value in the forensic practice. |
