摘要： 本实验采用非特异性酯酶Ｎｏｎ－ｓｐｅｃｉｆｉｃＥｓｔｅｒｓｅ（Ｎ．Ｓ．Ｅ）组织化学方法对生前与死后电损伤进行实验研究，发现生前与死后短时间内的电损伤皮肤胶原纤维上ＮＳＥ活性有显著差别（Ｐ＜０．０５），在相同实验条件控制下，电击后存活时间越长，电流斑皮肤周围的酯酶着色反应越深，范围越宽。实验结果表明，Ｎ．Ｓ．Ｅ对于鉴别生前电流斑与死后电流斑具有法医学意义。

Abstract: An experimental study was performed on antemortem and postmortem skin electricmarks by means of histochemical demonstration of nonspecific esterase (NSE ). The results reveales that NSE activity on the collagen fibers differed significantly (P＜0. 05)between antemorttem and postmortem skinelectric marks. Under the same experimentalconditions, the enzyme activity increaseswith the antemortem duration of the electricinjury. The study indicates that NSE activityis very useful in distinguishing antemortemand postmortem skin electric marks.

Key words: nonspecific esterasse, antemortem and postmortem electric marks.
