死后伤

结果发现：轴索直径在脑干伤0.5、1h组与死后伤组间无显著性差异，而3h组与死后伤组间差异有显著性。

Results showed : Axonal diameter has no significant difference among 0.5h , 1h antemortem injuries and postmortem injuries , but has significant difference between 3h injuries and postmortem injury .

心肌挫伤后的时序性变化规律使COX-2、bcl-2和HIF-1α有可能成为重度心肌挫伤时间推断的客观指标以及生前伤和死后伤的鉴别指标。

As an objective indication , the time sequence regularity of COX-2 , bcl-2 and HIF-1 α after severe myocardial contusion may be applied in severe myocardial contusion time estimation .

目的探讨大鼠弥漫性脑损伤后S100β在脑组织中不同部位的时间相关性表达，并以此为弥漫性脑损伤时间推断，生前伤和死后伤判断，早期诊断提供实验依据。

Objective To investigate the dynamics of the induction of S100 β in different parts of rat brain following the diffuse brain injury .

死后伤1h和3h时，TGF-β1mRNA的表达有增高的趋势，6h则降至对照水平。

In postmortem wounds , TGF - β 1 mRNA tended to increase 1 and 3 h after injury , and decreased to the control level at 6 h.

在死后伤组未见上述改变。

There were no changes of P-selectin in the postmortem incised group .

生前及死后伤皮肤中的酯酶活性

The Nonspecific Esterase Activity of Ante-and Postmortem Skin Wounds

本文报告对124个大鼠切割皮肤样本采用荧光光度法检测损伤皮肤纤维蛋白形成能，以探讨生前伤与死后伤的区别及不同存活时间的生前损伤之间的关系。

In this paper , We report fluorescene spectrophotometry in the determination of the fibrin-forming ability ( FA ) of 124 specimens of injured skin of rats to study the differences between the ante-mortem wounds and post-mortem ones and the relations with the ante-mortem wounds in different survivals .

生前及死后损伤骨骼肌的特异性染色明显，研究结果为法医学在确定生前与死后伤方面提供了可靠、敏感、客观的指标。

The results provided reliable , sensitive and objective index for the estimation of antemortem and postmortem injuries in forensics .
