低功率激光照射动物实验伤口的作用

本文报告了将71只长耳白兔制成实验性伤口,分别进行激光照射,着重进行形态学和组织学方面的探讨,结果发现 He-Cd 无效,He-Ne 和CO_2。激光有效。初步认为 He-Ne 激光促进伤口愈合的机理可能是改善其血液、淋巴循环、刺激纤维母细胞的增生。

Irradiation effect of low power laser on the healing of experimental animal wounds

Experimental results of excised wounds in the skin of 71 rabbits irradiated respectively by lasers are reported with emphasis on morphological and histologic investigation.No effect was observed for He-Cd laser,while obvious effect was manifested for He-Ne laser and CO2 laser. Preliminary conclusion is that the mechanism for promoting the healing of wounds may be the circulation improvement of blood and lymph,as well as stimulated generation of fibrOblasts.
