【摘要】：目的220V交流电击兔肢体后,观察电击部位骨表面的病理改变,为法医病理诊断电击伤提供客观、量化的指标。方法用220V交流电作为损伤电压。动物分为:生前电击组、死后5m in电击组、腐败组及正常对照组。每组骨骼标本均进行肉眼检察、X线检测及SEM观察;同时运用能谱仪测量电击部位元素的种类及含量。结果①电击部位骨皮质SEM下骨皮质紊乱、小孔穴形成、周围高密度影环绕,且钙、磷元素升高,碳元素下降是诊断电击伤的指标,并能鉴别生前、死后电击伤及腐败骨。②小孔穴的形态及钙、磷、碳元素的变化可用于推断电击时间。结论电击造成骨组织的形态及电击部位元素的改变可作为鉴别生前、死后电击伤、腐败骨和推断电击时间的指标。
[Abstract]:Objective to observe the pathological changes of bone surface in rabbit limb after 220V alternating electric shock, and to provide objective and quantitative index for forensic pathology diagnosis of electric shock injury. Methods 220 V AC was used as the damage voltage. Animals were divided into three groups: antemortem shock group, post-death 5 min electric shock group, putrefaction group and normal control group. Each group of bone samples were examined by X-ray and observed by SEM, and the kinds and contents of elements in electric shock site were measured by energy spectrometer. Results (1) the bone cortex was disordered under SEM at the electric shock site, the small hole was formed, the surrounding high density shadow surrounded, the calcium and phosphorus element increased, the carbon element decreased were the diagnostic indexes of the electric shock injury, and could distinguish the antemortem. The changes of calcium, phosphorus and carbon elements in the hole of the corrupted bone and the changes of calcium, phosphorus and carbon can be used to estimate the time of shock. Conclusion the changes of bone morphology and the elements in the electric shock site can be used as an index to distinguish between antemortem, postmortem electric injury, corrupted bone and extrapolation of electric shock time.
