从培养方法与气相色谱方法结果的对比中认为,气相色谱检测短链脂肪酸可以鉴别需氧菌或厌氧菌感染。在130(例)份胆汁的气相色谱分析中,53.8％为短链脂肪酸阳性。在肝内胆管结石病人56例中,细菌总检出率为92.2％,厌氧菌占75％。厌氧菌较强之组织破坏、β-葡萄醣醛酸苷酶生成及其在肝内胆管结石病人中多见,提示厌氧菌感染在肝内胆管结石生成中的可能作用。 From the comparison between the cultivation method and the gas chromatography method, it is considered that the detection of short-chain fatty acids by gas chromatography can identify aerobic or anaerobic infections. In the gas chromatographic analysis of 130 bites, 53.8% were short chain fatty acids positive. In 56 patients with intrahepatic bile duct stones, the total detection rate of bacteria was 92.2%, anaerobic bacteria accounted for 75%. More anaerobic tissue damage, β-glucuronidase and its occurrence in patients with intrahepatic bile duct stones more common, suggesting that anaerobic bacteria infection in the formation of intrahepatic bile duct stones may play a role.
