摘要

目前已有一系列调查方法来协助与爆炸有关的死亡调查,但使用组织病理学骨骼样本来诊断爆炸暴露和个人与爆炸源的距离,以前还没有报道过。法医组织病理学已有效用于软组织样本,以有效界定与爆炸有关的伤害,分析肺、脑、肝和骨骼肌等人体器官,提供重要而有用的法医病理学解释。然而,尽管硬组织骨骼样本的分解率明显低于软组织,为法医病理学实践提供了机会,但目前还没有研究对遭受爆炸的人类或动物骨骼的爆炸后组织学变化进行检查。本研究首次以证据为基础展示了三块动物骨骼在遭受近距离化学爆炸(C4)时发生的爆炸后组织学变化。研究的定性结果突出显示了三种不同动物骨骼来源的组织结构在爆炸效应下随着爆炸源距离的增加而发生的重要变化。这强调了组织病理学骨骼样本分析在未来与爆炸有关的死亡调查中的潜在用途,同时为进一步探索这项工作提供了思路,即利用更大规模的实验和爆炸后案例研究,将这项工作应用到人类样本和法医病理学实践中。

Post-blast histological changes to three animal bones exposed to close-range chemical detonation.

Post-blast histological changes to three animal bones exposed to close-range chemical detonation.

A range of investigative practices to aid explosive-related death investigations currently exist, although the use of histopathological bone samples to diagnose blast exposure and the distance of individuals from the blast source has not been previously reported. Forensic histopathology has been used effectively on soft tissue samples to define blast-related injuries effectively, analysing human organs such as the lungs, brain, liver, and skeletal muscles, providing important and useful forensic pathology interpretations. However, no studies currently exist examining the post-blast histological changes in human or animal bones subjected to blasts for forensic pathology practice, despite the opportunity that hard tissue bone samples present, given their significantly lower rate of decomposition over soft tissue. This study presents the first evidence-based findings on the post-blast histological changes in three animal bones when exposed to close-range chemical detonation (C4). The study's qualitative findings highlight critical changes in the tissue architecture of three different animal bone sources due to blast effects with range from the blast source. This emphasises the potential use of histopathological bone sample analysis in future blast-related death investigations, while providing ideas to further explore this work using larger-scale experiments and post-blast case studies in aid of applying this work to human samples and forensic pathology practice.

期刊介绍: The International Journal of Legal Medicine aims to improve the scientific resources used in the elucidation of crime and related forensic applications at a high level of evidential proof. The journal offers review articles tracing development in specific areas, with up-to-date analysis; original articles discussing significant recent research results; case reports describing interesting and exceptional examples; population data; letters to the editors; and technical notes, which appear in a section originally created for rapid publication of data in the dynamic field of DNA analysis.
