1、第30卷第2期中华中医药学刊Vol.30No.22012年2月CHINESEARCHIVESOFTRADITIONALCHINESEMEDICINEFeb.2012乐胃饮对慢性萎缩性胃炎大鼠血清氧自由基及胃黏膜组织形态的影响11211吴晋兰,陈展,朱飞叶,杨伟莲,夏露露(1.杭州市余杭区第五人民医院内科,浙江杭州311100;2.浙江中医药大学,浙江杭州310053)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、
2、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
