Abstract :

Introduction: Prediction of time since death is one of the most important object of postmortem examinations . Time passed since death continues to be a major problem for the forensic pathologist and its determination plays an important and vital issue in medicolegal cases because of the fact that forensic experts are very often required to answer questions relating to time of death in the courts of law Methods : Present study includes 30 human livers from cadaver were taken directly from the dead bodies during postmortem examination from Dr. B.R. Ambedkar Memorial Hospital Raipur (C.G.) in close association with Department of Forensic Medicine & Toxicology and Pathology. In the present study histological changes in architecture of hepatic lobule and hepatic cords and arrangement of hepatocytes of human liver were examined. Results : Increasing expansion of hepatic lobules were seen in relation to time after death and after 44hrs Post Mortem Interval (PMI) at 23.3-30.5�C disorganization of hepatic lobules were observed. Fragmentation of hepatic cords was observed after 13.30 hrs PMI at 29.1-43.1�C adjacent to central vein and was progressive in hepatic cords adjacent to portal triad in relation to time passage. Hepatic cords in subcapsular region were observed intact till 39.40hrs PMI at 24.3-32.2�C and there was complete fragmentation of hepatic cords with scattered hepatocytes after 44hrs PMI at 23.3-30.5�C. Hepatic lobules were not identifiable after 46 hrs PMI at 23.3 to 30.5 􀀀C. Conclusion : Thus Postmortem histological changes were directly dependant on not only the length of post-mortem time but also, to a bigger extent, on the temperature of environment.
