The objective of the present study was to develop the criteria for forensic-medical diagnostics of an electrical injury inflicted in the aqueous environment based on the characteristics of the electrical mark. The specific morphological features of the electrical injuries inflicted in the aqueous environment that were discovered in the materials available for the forensic medical expertise were analysed taking into consideration the results of the relevant research reported in the forensic medical literature. It was shown that an electrical injury inflicted in the aqueous environment results in the formation of an unusual mark in the form of blisters containing no watery liquid associated with electrogenic oedema in the surrounding tissues. Macroscopic and microscopic studies of the electrical mark failed to reveal the signs of grade III and IV grade thermal burning or thermally affected hair. It is concluded that the consistent characteristics of the electrical mark resulting from the injury inflicted by technical electricity in the aqueous environment include cell lengthening, blister formation inside the corneal layer, and the separation of epidermis from the skin proper.
本研究的目的是根据电痕特征制定水环境中电损伤的法医诊断标准。结合法医学文献中相关研究结果，对法医鉴定可用材料中发现的水环境中电损伤的特定形态学特征进行了分析。结果表明，水环境中的电损伤会形成一种异常痕迹，表现为含有与周围组织电源性水肿相关的无水性液体的水泡。对电痕的宏观和微观研究未发现III级和IV级热烧伤或热损伤毛发的迹象。得出的结论是，技术电流在水环境中造成损伤所产生的电痕的一致特征包括细胞拉长、角质层内水泡形成以及表皮与真皮分离。
