摘　　要：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。Public security bureau of Gaomi CityShndong Province 261500This paper reporte a method for estimating the time of death by determing the cornea endothelial cell living rate (ECLR). 500 corneas were taken from corpses of knowen time of death and were studied according to the method reported previously. The living and the total cells were counted and their ration (ECLR) was calculated. It was found that the ECLR was decreasing along with lengthen-ing the postmortem interval. So that it is suggested that this method provided a tool for estimating time of deth.
