口腔与胃中幽门螺旋杆菌相关关系研究

目的 探讨胃与口腔幽门螺旋杆菌分布有无差异性。口腔是否为幽门螺旋杆菌的一个重要储存库方法随机选取经内窥镜证实患慢性胃炎或十二指肠溃疡的患者50名，分别从胃与121腔中取标本进行快速尿素酶、多聚酶链反应和细菌培养以测定幽门螺旋杆菌的存在。对所得的数据进行统计学分析。结果 胃粘膜标本组中快速尿素酶法获45例阳性，多聚酶链反应34例阳性，细菌培养25例阳性。口腔牙菌斑组中快速尿素酶法41例阳性。多聚酶链反应28例阳性，细菌培养17例阳性。结论 胃粘膜与121腔幽门螺旋杆菌分布无差异性。

The study of the relation of HP between stomach and oral cavity

Objective The study was to research into the difference of HP between stomach and oral cavity and explore whether the oral cavity was an important reservoir of HP. Methods Fifty adult chronic gastritis or duodenal ulcer patients who underwent gaseroscopy were randomly selected. The presence of Helicobacter pylori in playues and mucous were soughot by the rapid urease test. Polymerase chain reaction(PCR) and culture. At last, the positive results were recorded and the data were dealed by stastic analysis. Results In grasp of gastric mucous, the rapid urease test was positive in 45. PCR was positive in 34. Culture was positive in 25. In group of dental plaque, the rapid urease test was positive in 41, PCR was positive in 28, culture was positive in 17. Conclusion The results show that the distribution has no difference between stomach and oral cavity.
