    幽门螺杆菌阳性的慢性胃炎患者胃黏膜组织中TNF-、IL-1、iNOS的表达

    Study of the correlation of iNOS,TNF-a and IL-1ingastric mucosa tissues in patients with Helicobacter pylori associated gastritis

    • 摘要: 目的:探讨幽门螺杆菌(Hp)阳性的胃炎患者胃黏膜组织中诱导型一氧化氮合酶(induciblenitricoxidesynthase,iNOS)、肿瘤坏死因子(tumornecrosisfactor-,TNF-)和白细胞介素1(interleukin-1,IL-1)的表达水平。方法:选择以胃镜和组织学检查诊断为Hp阳性的慢性胃炎126例患者作为研究对象(Hp阳性组),以122例Hp阴性的慢性胃炎患者为对照组(Hp阴性组)。通过组织学方法评定胃黏膜病理组织学改变,采用快速尿素酶试验及改良Giemsa染色法对受检对象作Hp感染诊断,放射免疫法检测TNF-、IL-1水平,免疫组织化学方法检测胃黏膜组织中iNOS表达。结果:Hp阳性组胃黏膜炎症程度重于Hp阴性组(p0.01)。Hp阳性组胃黏膜中TNF-、IL-1、iNOS水平均高于Hp阴性组(p0.05)。结论:Hp阳性的胃炎胃黏膜呈现一种炎症改变,可能与细胞因子TNF-、IL-1、iNOS分泌增加有关。

       

      Abstract: To study the correlation oI inducible nitric oxide synthase(iNOS),tumor necrosis factor(TNF)andinterleukinp(ILKp)in gastric mucosa tissues in patients with Helicobacter pylori(Hp)associated gastritis. Methods:One hundredand twentyix cases oI Hp inlected chronic gastritis and 122 cases oI Hp uninlected chronic gastritis were included in the study. Thediagnosis oI chronic gastritis was established by gastroscopy and histological examination. The Hp inlection was detected by rapid ureasetest and Giemsa stainning. The levels oI TNF and ILKp were determined by immunoradiometric assay and the expression oI iNOSwas determined by immunohistochemistry.
