QUANTITATIVE ANALYSIS OF TISSUES CELL DNA CONTENT IN DIFFERENT POSTMORTEM INTERVAL / 中国法医学杂志

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.
