ABSTRACT
Time since death is made out from gross postmortem changes like cooling of the body, postmortem staining, rigor mortis, decomposition etc. In the present study Histological changes in the Kidney tissue were studied at various postmortem intervals in the human body died due to road traffic accidents. This study is conducted in the Department of Forensic Medicine in collaboration with Department of Pathology, G.S.V.M. Medical College, Kanpur, U.P. A total of 45 cases are taken belonging to both sexes i.e. 36 males and 9 females were studied. These are of different age groups. All road traffic accidents are taken into account. In this study control can not be taken because the histological changes of tissue after death is influenced a great deal by atmospheric temperature and humidity besides other external and internal factors. Therefore these must be taken into account in all studies of postmortem interval whether histological, biochemical or physical.
