摘要
为探讨胃液酸度对幽门螺旋菌(HP)的影响,我们对609例胃、十二指肠疾病患者进行HP检查和pH值测定,结果发现:在257例胃液pH≤2.0患者中,HP阳性率为47.5％(112/257),在311例HP阳性患者中,pH≤2.0者占39.2％(122/311);胃液pH≥4.0患者的HP阳性率高于HP<4.0者,且阳性率有显著差异(P<0.05);另外,十二指肠溃疡患者在高胃酸环境下HP阳性率较高(为75％),并对其阳性率较高的机理进行了探讨。
To study the effect of gastric acid on Helicobacter pylori (HP), the HP and pH in 609 cases with gastric and duodenal disease were examined.The results showed that a HP positive rate was 47.5% (112/257) in 257 cases with gastric liquid of pH≤2.0;39.2% (122/311)of the cases with HP positive were found to have a gastric acid of pH≤2.0. The HP positive rate in the cases of pH≥4. 0 was obviously higher than that in those of pH<4.0 (P<0.05). The HP positive percentage, however, seemed to be higher (7.5％) in the cases with duodenal ulcer with high gastric acid. The machanism that the positive rate of HP increased in duodenal ulcer victims was discussed.
