以往研究提示细菌在色素胆结石的发病和临床表现中起特殊的作用,本文用电子扫描显微镜(SEM)研究胆石的形态学,测定细菌对体外色素和胆固醇结石表面的亲和性.取二组结石,一组32例新鲜结石,另一组53例干燥结石,其中取自胆囊和胆总管色素结石分别为24例和18例,胆固醇结石分别为27例和17例,混合型胆石分别为9例和11例.全组中,仅5例长期居住在东方.SEM确定有无细菌微集团固定在其表面.每一份细菌培养液作涂片,用钌红染色,测定其中糖被膜.结果: 一、结石形态学一胆固醇和色素结石的肉眼和SEM所见有明显区别: (1)色素结石的表面不
Previous studies have suggested that bacteria play a special role in the pathogenesis and clinical manifestations of pigmented gallstones. In this paper, the morphology of gallstone was studied by scanning electron microscopy (SEM), and the affinity of bacteria to the surface of the pigment in vitro and cholesterol gallstone was measured. Stones, a group of 32 cases of fresh stones, the other group of 53 cases of dry stones, of which from the gallbladder and choledocholithiasis were 24 cases and 18 cases of cholesterol stones were 27 cases and 17 cases of mixed gallstone were 9 Cases and 11 cases.In the group, only 5 cases lived in the East for a long time.SEM to determine whether there are bacterial micro-colonies fixed on its surface.Each bacterial culture liquid smear, ruthenium red staining, the determination of the sugar coating.Results : First, the morphology of a stone Cholesterol and pigment stones and the naked eye SEM see a clear difference: (1) the surface of pigmented stones is not
