摘要:

目的 验证死后伤能否引起软组织出血。方法 通过构建大鼠死后伤模型,经常规照相观察、HE染色并镜检,以及蛋白免疫印记实验,对死后伤软组织出血状况进行研究。结果 死后伤软组织部位出现明显出血点,HE染色后镜检发现软组织部位出现大量红细胞,western blot结果显示死后伤部位软组织中的血红蛋白含量明显高于对照。结论 死后伤同样能够形成软组织出血,传统法医学理论认为的“损伤部位出现软组织出血是生前伤的主要依据”并非绝对成立,且证实流体静压力是软组织出血的原因。

Abstract:

Objective To verify whether postmortem injury could cause the hemorrhage in soft tissue. Methods The rat model of postmortem injury was constructed. Anatomical observation, HE staining and western blot experiment were performed to study the hemorrhage in soft tissue. Results Bleeding points were observed in soft tissue. Microscopic examination showed that plenty of red cells emerged in soft tissue. According to the western blot results, hemoglobin was highly expressed in the soft tissue of rats in postmortem injury group. Conclusion The hemorrhage of soft tissue could occur in postmortem injury. The traditional forensic medicine theory that the hemorrhage in soft tissue is the definite indication of injury before death has been overthrown. Moreover, it has been verified that the formation of hemorrhage in soft tissue results from hydrostatic pressure.

Key words: postmortem injury, soft tissue, hemorrhage, hydrostatic pressure
