本文应用酶联免疫吸附试验(ELISA)检测50例消化不良者和20名健康志愿者的唾液和血清中抗幽门螺杆菌IgG抗体,检验结果与组织学所见、细菌培养结果和尿素酶检验进行比较。分别取胃窦和胃体多个活检标本进行HE染色判定胃部病灶的有无和严重程度,改良的Giemsa染色证实幽门螺杆菌的存在,以细菌培养和尿素酶试验检测幽门 In this paper, anti-Helicobacter pylori IgG antibodies against H.pylori in saliva and serum of 50 patients with dyspepsia and 20 healthy volunteers were detected by enzyme-linked immunosorbent assay (ELISA). The results of the tests were in accordance with histological findings, bacterial culture results and urease tests Compare Multiple biopsies of gastric antrum and corpus were taken to determine the presence and severity of gastric lesions by HE staining. The presence of Helicobacter pylori was confirmed by modified Giemsa staining. The pylorus was detected by bacterial culture and urease test
