在我国,常见和难于治疗的胆管结石主要是胆色素类结石。斋藤达雄曾将此类结石患者的胆汁在体外保温后形成沉淀,与同一患者的结石用化学定量分析、纸上电泳和红外吸收光谱等方法进行比较,发现沉淀与胆石极其相似。因此认为这种沉淀可能是结石形成的第一步。以后,槙哲夫等用这种沉淀来研究由 In our country, common and difficult to treat bile duct stones are mainly bile pigment stones. Saito Daixiong had such stones in patients with bile deposition in vitro after the formation of heat, and the same patient with stones by chemical quantitative analysis, paper electrophoresis and infrared absorption spectroscopy and other methods to compare and found that precipitation and gallstone are very similar. It is therefore believed that this precipitation may be the first step in the formation of stones. Later, Tetsuhiro et al. Used this sediment to study
