Abstract

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.
猫尸体实质器官在死后早期的细胞形态学变化在法医兽医检验方面
从法医兽医检验的角度,建立了猫尸体实质器官在死后早期的细胞形态学变化。这项工作的目的是阐明动物死亡后第一天在有氧环境下的细胞水平上的坏死过程,作为法医兽医检查在尸检早期确定死亡年龄时的细胞形态学标准。结果表明,脾脏和胰腺组织的细胞形态学变化最为动态;肝、肺和心脏组织的细胞结构变化较少。肾组织和脑组织未见明显的细胞形态学改变。结果发现,实质器官标本细胞学研究在死后第一天后才确定细胞的组织学形态是不可能的。发现肾脏和脑组织的细胞结构动力学不能解决法医兽医检查的问题,但肝、肺和心脏细胞的坏死情况可以提供适度的信息。脾脏和胰腺组织的细胞形态学图像变化具有很高的信息量,因为细胞形态学变化动态的强度与其解决死亡年龄问题的信息量直接相关。建议在法医兽医检验实践中使用细胞学快速方法,以解决动物死亡年龄在晚期尸体现象出现之前的不明显问题。
