摘要
目的 :探讨一氧化氮 (NO)及超氧化物歧化酶 (SOD)在口腔扁平苔藓 (OLP)发病中的作用。方法 :选择OLP患者 30例 (其中糜烂型 12例 ,非糜烂型 18例 )及健康献血员 30例 ,分别采集组织标本和血清标本 ,检测NO含量 (硝酸还原酶法 )和SOD活性 (黄嘌呤氧化酶法 ) ,所得数据采用配对t检验进行统计学处理。结果 :组织与血清中NO值 ,OLP组均高于正常对照组 (P <0 .0 5 ) ,糜烂型虽高于非糜烂型 ,但无统计学差异 (P >0 .0 5 ) ;组织与血清中SOD值 ,OLP组均明显低于正常对照组 (P <0 .0 1) ;而糜烂型与非糜烂型比较 ,SOD值均下降 ,但血清中SOD值差异不显著 (P >0 .0 5 )。结论 :在OLP发病的不同阶段 ,NO含量及SOD活性呈动态变化 ,随着病变程度加重 ,NO含量明显升高 ,SOD活性明显下降 ,导致局部组织免疫反应异常 ,二者可能发挥协同作用 ,参与OLP的发病。
Objective:To study the role of nitric oxide(NO) and superoxide dismutase(SOD) in oral lichen planus(OLP).Method:30 OLP patients and 30 healthy donors (control group) were involved in this study.NO level and SOD activity in tissues and serums were measured respectively.Result:NO level in OLP group was higher than control group(P< 0.05),but,there was no significant difference between erosion type and non-erosion type(P> 0.05).SOD activity in OLP group was significantly lower than control group(P< 0.01),but there was no significant difference in serum between erosion type and non-erosion type(P> 0.05).Conclusion:NO level and SOD activity were changed dynamically in different developmental stage of OLP.The lower SOD activity and higher NO level may cooperate and thus lead to prolonged course of OLP.
