Abstract： 目的:探讨胆囊结石中晶体物质的组成、形态和结构及其在胆囊结石形成与生长过程中的作用.方法:在单盲的条件下,分别用偏光显微镜、扫描电镜和X射线衍射仪对35例人体胆囊结石的晶体结构、剖面超微结构及晶体组成进行观察研究.结果:颗粒状胆囊结石尽管其外观和剖面的形态结构各不相同,但都以结晶态物质为主,其主要成分为胆固醇晶体.晶体的干涉色级为二级蓝绿,双折射率△n=0.022-0.025.胆石中的晶体以密集分布的微晶体和微晶体集合体的形式存在,其间隙被非晶物质填充.泥沙状结石以非晶态物质为主,其主要成分是胆色素和胆色素盐,属胆色素结石.结论:人体胆囊结石是一种特殊的生物晶体.胆囊内多变的结晶环境并不支持胆固醇晶体的完整发育,胆固醇晶体构成了颗粒状胆囊结石的基本架构,非晶物质的沉积促使了结石的进一步生长.
