创伤膏促进大鼠创面修复的实验研究

目的：通过观察创伤膏对大鼠创面修复的影响，初步探讨创伤膏促进创面修复机制。方法：将大鼠背部左右侧各切取直径2cm大小的皮肤，深及皮下筋膜、肌肉，造成创面模型。将大鼠随机分为3组，空白对照组、龙珠软膏组、创伤膏组。进行形态学观察，创面面积测量，组织学观察（光镜和透射电镜）及创面分泌物细菌培养。结果：创伤膏明显促进创面愈合，防止瘢痕孪缩硬化及过度增生。结论：创伤膏对创面修复有一定的疗效。

Empirical Study of Wound Ointment on restoration the Raw Surface of Rats

Objective: To approach the repair mechanism of wound ointment to facilitate the raw surface by observing the effect of wound ointment on restoration the raw surface of rats. Method: the wound model was found as follow: 2cm raw surface were cut in right and left on rats back and deep to superficial fascia. Rats were randomly allocated to three groups as follows: control, Japanese tubocapsicum dragonpearl herb ointment and wound ointment. The morphology, raw surface areas, histology and bacterial culture in raw surface excretion were observed. Result: wound ointments have the function to facilitate the recovery of raw surface, prevent sclerization and spasm of the cicatricle. Conclusion: wound ointments have the effect to recovery the raw surface.
