Cytomorphological changes of a cat’s cadaver’s parenchymal organs in the early postmortem period in the forensic veterinary examination aspect

The cytomorphological changes of a cat’s cadaver’s parenchymal organs in the early postmortem period in the aspect of forensic veterinary examination are established in the work. The aim of the work is to clarify the processes of necrobiosis at the cellular level under aerobic environment in the first day after the death of the animal as a cytomorphological criterion in terms of forensic veterinary examination in deciding the age of death in the early postmortem period. It is proved that the most dynamic cytomorphological changes are found in the spleen and pancreas tissue; cytoarchitectonics of liver, lung and heart tissue changes less intensively. Intense cytomorphological changes in kidney tissue and brain were not observed. It was found that parenchymal organs samples cytological research after the first day of the postmortem period to determine the cells histological topography is impossible. It was found that the cytoarchitectonics dynamics of kidney and brain tissue is uninformative to solve the problems of forensic veterinary examination, but the necrobiosis of liver, lung and heart cells is moderately informative. High informativeness of cytomorphological picture change in spleen and pancreas tissue has been established, as the intensity of cytomorphological changes dynamics and their informativeness to solve the question of the age of death are directly correlated. It is recommended to use the cytological rapid method as an additional in the practice of forensic veterinary examination to address the issue of animal death age in terms of its non-obviousness before the appearance of late cadaveric phenomena.
