Intraluminal H2 concentrations were measured by gas chromatography. 结果。分别在566(87.5%)和524(81.0%)患者中检测到胃内和十二指肠内H 2气体。胃内内和十二指肠内氢气的meanvalues是 8.5 ± 15.9 13.2 ± 58.0  ppm, respectively. The intraduodenal H2 level wasincreased with the progression of atrophic gastritis, whereas the intragastric H2 level was the highest in patients without atrophic gastritis. 结论。十二指肠内氢水平与萎缩性胃炎的进展而增加。很可能的胃酸对细菌过度生长在近端小肠的影响更加明显,相比thatin胃。SN - 1687-6121 UR - https://doi.org/10.1155/2008/584929 DO - 10.1155 /五十八万四千九百二十九分之二千零八JF - 消化内科的研究与实践PB - Hindawi出版公司公司KW - ER -
