【摘 要】 目的 探讨门脉高压性胃病(PHG)与幽门螺杆菌(HP)感染或血清NO浓度之间的关系。 方法 PHG患者60例，通过内镜检查诊断，胃黏膜活检(每例4块)用改良Giemsa染色法检测HP。NO测定采用硝酸还原酶法。 结果 PHG患者的HP阳性率为68.3%(41/60)，PHG组与对照组胃液或血清NO水平比较，差异有显著性(P<0.05);HP阴性与阳性组PHG胃液或血清NO水平之间比较，差异有非常显著性(P<0.01)。 结论 PHG患者的胃黏膜病变与HP感染有密切关系。

    【Abstract】 Objective To study the relationship between portal hypertensivegastropathy(PHG)and infection of helicobacter pylori(HP)or NO.Methods PHG patients(n=60)were investigated by endoscopy and4mucosal biopsy samples from each pa-tient were studied by reformed Giemsa stain method.Results The total positive rate of HP infection in PHG patients were68.3%(41/60cases).In PHG with peptic ulcer it was53.7%(22/41cases) ......
