五味粉治疗复发性口疮作用探讨

目的：对五味粉局部治疗复发性口疮（RAU）的疗效进行评价。方法：将211例RAU患者随机分为两组；实验组113例，对照组98例，分别用五味粉和冰硼散于溃疡面黏附外用，每日早、晚各1次，观察其临床效果。结果：疮疹样口疮及重型口疮两组疗效比较，差异无统计学意义（P〉0．05）；轻型口疮两组疗效比较实验组优于对照组（P〈0．01）。结论：应用五味粉治疗RAU，特别是轻型效果良好，简单易行，值得临床推广应用。

Efficiency of Wu-wei power on recurrent aphthous ulcer

Objective:To observe and evaluate the efficiency of Wu-wei power on recurrent aphthous ulcer(RAU).Methods:By unilateral-blind random method,211 patients with RAU were selected and divided into two groups:113 in experimental group and 98 in control group;twice a day,patients in former group were treated by topical-applying Wu-wei power on the surface of recurrent aphthous ulcer each morning and evening after the site around RAU was cleaned with 0.9% NaCl,while patients in latter group were treated with Bing-peng power.Observed and compared the clinical effect of two groups.Results:There was no significant difference between the effect on herpetiformis aphtha and severe aphtha(P>0.05).The effect on light aphtha in experimental group was more obvious than in control group(P<0.01).Conclusion:It's a efficient way to treat patients with RAU,especially with minor aphthous ulcer by topical-applying Wu-wei power.
