CO_2与He-Ne激光照射治疗慢性溃疡的机理探讨

On the healing mechanism of skin ulcer with CO_2 and He-Ne lasers

我院三年来,应用CO2和He-Ne激光照射治疗慢性溃疡、术后伤口不愈和各种原因的创面,均取得了肯定的疗效。共治各种溃疡276例,全愈229例,占82.97％;好转33例,占11.95％;无效14例,占5.08％ 为了探讨低功率激光照射的创面愈合机理,我们做了以下两个实验。 1.低功率激光对创面直接影响的观察 选择12例溃疡患者,应用He-Ne与CO2激光照射,功率密度分别为4～5毫瓦/厘米2和0.2瓦/厘米2,每次照射前均用无菌操作法取分泌物作细菌培养,结果阳性者经菌种鉴定后划平皿供激光照射实验用。

In order to investigate the healing mechanism of skin ulcers, the plate innoculated with staphylococcus aureus and pseudomonas aeruginosa was irradiated with low power CO2 and He-Ne laser light, becteria was not inhibited obviously.
