Methods: 408 cases of mild recurrent oral ulcers were randomly divided into two groups: The patients in experiment group were treated with riboflavine laurate 150 mg one time a week, last three period and routine treatment, while the patients in contorl group received only routine treatment. Total effective rate and the level of IL-2 before and after treatment in two groups were contrasted.

408例轻型复发性口腔溃疡患者随机分为两组，对照组采用常规治疗，核黄素治疗组在常规治疗基础上一次性肌肉注射长效核黄素150mg，每周1次，共用3个周期，比较两组总有效率及治疗前、后IL-2水平。

Taking Eremothecium ashbyii (abbreviated as Eaw95. 1) as the original strain, after Υ-ray mutation, tubercidin and 8--azaguaniae (8--AG) resistant tests, a strain labeled as T〓 capable of overproducing riboflavin was obtained and its genetic stability was analyzed. Compared with Eaw95. 1, the riboflavin productivity was improved about 40% by flask--shaking tests.

以Eremothecium ashbyii为出发菌（间称Eaw95.1），通过Υ-射线诱变，杀结核菌素和8-氮杂鸟嘌呤等结构类似物的的抗性筛选，获得了一株核黄素高产菌T〓，并对菌株的遗传稳定性进行了研究，获得了较好的效果，与出发菌株相比，核黄素的摇瓶发酵产量提高了近40％。

Baker yeast BY-1-8, Candida yeast CY-1-11, beer yeast SY-1-10 and milk brewer yeast MY-1 were used for a group of tests. Through the tests, the yeast strain (MY-1), which had the maximum riboflavin and extraction, was selected.

通过对面包酵母(BY-1～8)，假丝酵母(CY-1～11)，啤酒酵母(SY-1～10)，奶酒酵母(MY-1)等四种酵母的核黄素、自溶浸出物比率进行研究，选定了核黄素含量及自溶浸出物比率较高的奶酒酵母(MY-1)作为出发菌株。
