摘　　要：目的:观察乐胃饮对慢性萎缩性胃炎大鼠血清SOD和MDA含量及胃黏膜组织形态的影响。方法:60只Wistar大鼠,随机分为正常对照组、模型组、维酶素组、乐胃饮低、中、高剂量组,除正常对照组外,其余大鼠用2%水杨酸钠灌胃、自由饮用MNNG溶液结合饥饱失常等综合因素诱发慢性萎缩性胃炎模型。造模后各组予以灌胃治疗4周。结果:与模型对照组比较,乐胃饮中、高剂量组的SOD含量显著升高(P<0.01,P<0.05),乐胃饮中、高剂量组和维酶素组MDA含量显著降低(P<0.01)。形态学结果显示乐胃饮具有改善胃黏膜形态的功能。结论:乐胃饮可提高大鼠血清SOD活性,减少血清MDA含量,能有效清除氧自由基,具有良好的抗氧化作用;对慢性萎缩性胃炎的病理形态改变也有较好的改善作用。Objective：To observe the effect of Leweiyin on the serum SOD, MDA and gastric mucosal morphology in rats with chronic atrophic gastritis. Method：60 Wistar rats were randomly divided into 6 groups： normal control group, model group, Weimeisu group, Leweiyin with low - dose, medium - dose and high - dose group. Except the normal control group, the rest five groups of chronic atrophic gastritis model were induced by administering intragastrically with 2% sodium salicylate, a free drink with MNNG solution and a combination of other factors such as irregular diet. Afterwards, corresponding medication was administered to each group for d weeks. Results： Compared to the model group, SOD levels in the medium - dose and high - dose Leweiyin groups significantly higher（ P 〈 0.01, P 〈 0.05 ） while the contents of MDA in the medium- dose and high -dose Leweiyin groups and Weimeisu group were significantly lower（ P 〈 0.01 ）. And Leweiyin can improve the gastric mucosa morphology. Conclusion ： Leweiyin could increase the activity of serum SOD reduce serum MDA. It could remove oxygen free radicals and had a good function of anti - oxidation. It also had a better effect on the pathological changes of gastric morphology.
