摘要:目的研究两面针总碱(TAZ)对胃溃疡大鼠部分黏膜防御因子的影响,以探索其抗溃疡机制。方法幽门结扎法建立SD大鼠胃溃疡模型,检测胃溃疡指数、胃黏膜组织和血清一氧化氮(NO)含量、血浆前列腺素E2(PGE2)含量。结果连续7 d灌胃分别给予500 mg/kg和750 mg/(kg·d)-1 两面针总碱能明显抑制胃溃疡指数的升高 (P<0.01),能明显抑制胃黏膜组织和血清NO含量的降低(P<0.01),两面针高剂量组明显抑制血浆PGE含量的降低 (P<0.05)。结论 两面针总碱有抗胃溃疡作用,这种作用可能与提高胃黏膜组织和血清NO,血浆PGE2的含量有关。关键词:两面针总碱; 溃疡指数; 一氧化氮; 前列腺素E2

Abstract:ObjectiveTo observe the effect of total alkaloids from Zanthoxylum nitidum (TAZ) on some gastric mucosal defensive factors in rats with gastric ulcer and to explore its antiulcer mechanisms.MethodsA gastric ulcer model was established by ligation pylorus in rats. The ulcer index, serum and gastric mucosa nitric oxide(NO) level ......
