不同活力组织的光学特性以及光学法在判定高速枪伤伤道周围组织坏死界限中的作用

The Changes of Respiratory Enzymes in Mitochondrial and Its Clinical Significance in Determinins the Areas of Damaced Tissue

本实验采用生化与生理指标相结合的力法,观察了高速枪伤后伤道周围不同分区组织的转归及其规律,并就其机理进行了探讨。结果表明:与ATP生成密切相关的琥珀酸脱氢酶、H^+-ATP酶活力在伤道周围不同分区均有下降,并发生在组织结构改变之前,随伤后时间的延长以及处理方式的不同而转归各异。在非清创条件下,挫伤区以及震荡区组织的转归常经历一个“损伤—相对稳定—再损伤”的过程,而早期清创便可以显著改善这两部分组织的预后。

The tissue functione nd its progress after gunshot wounds are studied with biochemical and pathophysiological methods.The experimental results show that the activity of succinate dehydrogenase and H+-ATP enzyme are lower at the various areas surrounding the wound channel.The changes of respiratory enzyme activity precede that of its tissue structure and have different results according to different treatment.In the non-debridement condition changes of the function of the bruised and shocked tissue may be the course of damaging-recovery and redamaging.The early debridement may make good results of these two areas.
