摘要:

背景:复发性阿弗他溃疡的具体发病机制目前医学界尚无定论,其中体内氧自由基的增多是引起复发性口腔溃疡反复发作的原因之一。

目的:观察超氧化物歧化酶对复发性阿弗他溃疡治疗效果的影响。
方法:在24只复发性阿弗他溃疡家兔模型建立后,按随机数字表法分为3组。模型对照组作为对比不做处理;阴性对照组家兔每天局部碘甘油擦拭;超氧化物歧化酶组家兔每天进行超氧化物歧化酶生物胶囊溶液灌胃,溃疡局部用碘甘油进行擦拭。1周后切取口腔溃疡病变组织进行对比研究。各组家兔造模后,每隔3 d上午同一时间兔耳静脉采血,流式细胞仪分析T细胞亚群CD3+、CD4+、CD8+以及CD3+/CD8+变化。
结果与结论:当溃疡病变形成后,模型对照组和阴性对照组家兔外周血中细胞CD3+、CD4+、CD4+/CD8+的比值经过统计均明显低于正常,而CD8+细胞数远远大于正常数值。超氧化物歧化酶组灌服超氧化物歧化酶生物胶囊后,CD3+、CD4+细胞数开始逐渐升高,而CD8+细胞数则相反呈下降趋势。提示应用氧自由基的天然清除剂超氧化物歧化酶就能有效清除溃疡面中过量的氧自由基,从而达到临床上治疗复发性阿弗他溃疡的目的。

Abstract:

BACKGROUND: The precise pathogenesis of recurrent aphthous ulcers remains controversial in present medical science. Oxygen free radical increase in the body is one of the causes of recurrent aphthous ulcers.

OBJECTIVE: To observe the effects of superoxide dismutase on the therapeutic effect of recurrent aphthous ulcers.
METHODS: After establishing 24 rabbit models of recurrent aphthous ulcers, they were randomly assigned to three groups. Model control group as a contrast was not treated. Rabbits in the negative control group were cleaned with iodoglycerin in local region daily. Rabbits in the superoxide dismutase group were intragastrically administered with superoxide dismutase capsule solution. Local ulcer was cleaned with iodoglycerin. One week later, tissue with oral ulcer lesions was obtained and compared. In each group, after model establishment, blood was collected from rabbit ear vein at the same time in the morning every 4 days. Flow cytometry was used to analyze the changes in T cell subsets CD3+, CD4+, CD8+, and CD3+/CD8+.
RESULTS AND CONCLUSION: When the ulcer lesions formed, peripheral blood CD3+, CD4+, CD4+/CD8+ ratio through statistics was apparently lower than normal levels in the model control group and negative control group. However, the number of CD8+ cells was greatly more than normal value. In the superoxide dismutase group,  after administrated with superoxide dismutase capsule, the number of CD3+ and CD4+ cells was gradually increased, but the number of CD8+ cells showed a decreased trend. These data suggested that natural scavenger superoxide dismutase using oxygen free radical can effectively scavenge excessive oxygen free radical in the ulcers, resulting in treatment of recurrent aphthous ulcers.
