本研究对已知死亡时间的500只非正常死亡者的角膜内皮细胞进行染色观察，以单位面积内的活性内皮细胞与细胞总数之比作为活性率，发现角膜内皮细胞活性率（Endothelialcelllivinsrate，ECLR）随死后经过时间（postmorteminterval，PMI）的延长而逐渐降低，数理分析表明两者之间的关系为负相关，因此，认为检测尸体角膜内皮细胞活性的方法可为法医学推断死后经过时间提供一新的组织学手段。 In this study, the corneal endothelial cells of 500 non-normal deaths at known time of death were stained. The ratio of active endothelial cells to total number of cells per unit area was taken as the activity rate, and the activity of endothelial cell (ECLR) Therefore, it is considered that the method of detecting the corneal endothelial cell activity may be provided by forensic inference of the elapsed time after death New histological approach.
