胃幽门弯曲菌在胃癌患者胃内的分布

DISTRIBUTION OF CAMPYLOBACTER-PYLORIDIS IN STOMACH OF GASTRIC CANCER PATIENTS

本文采用Warthin-Starry镀银染色、吖啶橙荧光染色、细菌培养等技术对52例胃癌患者胃内幽门弯曲菌的分布进行了检测。结果表明:该菌在胃内的分布是非均一的,胃窦部阳性率高于胃底贲门部,多部位取材有助于提高检菌阳性率;该菌在胃癌患者胃内有较高的分布(65.4％),其中早期胃癌中阳性率较高(80.0％)。癌周取材检菌阳性率(64.0％)高于癌组织(26.9％),提示该菌可能与胃癌的发生有关。

The Distribution of campylobacter-pyloridis in 52 cases of gastric cancer was examed with the skills of Warthin-Starry silvering, Ao-fluorescence and bacteria culture etc. The results showed that the distribution of campylobacter-pyloridis in stomach was uneven. The positive rate was higher at antrum than that at cardia. It was helpful of increasing the positive rate for detecting the campylobacter-pyloridis by means of drawn material from multiple sites. The distribution of campylobacter-pyloridis was high in stomach of gastric cancer patients(65.4％), and among them, the positive rate of early gastric cancer was more higher (80.0％). The positive rate was higher by drawn material about the tumor than that at the tumor. It suggested that the campylobacter-pyloridis might be responsible for the occurrence of gastric cancer.
