短波紫外线与氦氖激光照射对感染性伤口愈合影响的研究

研究短波紫外线与氦激光照射对感染性伤口愈合作用的影响，并判别其作用的差异性。方法将５０只Ｈａｒｔｌｅｙ豚鼠随机分为３组：ＵＶＣ组、激光组各２０只，对照组１０只。首先在豚鼠背部造成实验性感染伤口，感染４８ｈ后进行治疗，每天１次，９次为１疗程。

Research on treatment of infected wound by ultraviolet C and He-Ne laser irradiation

Objective To study the healing effect of ultraviolet C(UVC) and He-Ne laser irradiation on the infected wound and distinguish the effect of UVC from He-Ne laser.Methods 50 Hertley quinea-pigs were artificially formed the infected wound on back of quinea-pig,and were randomly divided into UVC group,laser group and contrast group(without any special treatment).After 48 hours of infection,the UVC or He-Ne laser was given,once a day,for 9 times.Before and after the 3rd,6th,9th day of treatment,the alteration of infected wound was observed,the WBC of eye venous blood was detected and the incised skin tissue was histopathologically analysed by light and electron microscope.Results The healing effects of UVC and laser group were all better than the contrast group.The effect of UVC was superior to the laser.Conclusion The study demonstrates that both UVC and He-Ne laser have the effect to promote the healing of infected wound,especially the result of UVC is better.
