| 摘 要： | 本文应用流式细胞仪对大鼠死亡后不同时间的心、肝、肾组织细胞DNA含量进行了分析。结果显示:与死后0点细胞DNA含量值相比,6小时细胞DNA含量下降到99.5％,12小时为91.3％,18小时为87.1％,24小时为81.3％,30小时为76.7％,36小时为74.3％,48小时为72.3％。上述规律性变化,将可能对早期死亡时间的推断提供客观可靠的依据。

| Abstract: | Cell DNA content in heart, liver, kidney of rats were analysed by flow cytometer at different postmortem interved. The rsults show that mean cellular DNA content is 99.5% at 6 hours, 91.3% at 12 hours, 87.1% at 18 hours, 81.3% at 24 hours, 76.7% at 30 hours, 74.3% at 36 hours, 72.3% 48 hours as compared with that at o hours The results ingicates that the quantitative determination of cell DNA in the tissues, mentioned above may provide an objective and reliable approach for the estimation of postmortem time. |
