Twenty Six mixed infective and 2 cholesterol gall-stones were stained for cholesterol, calcium, fat and mucoproteins. Calcium and cholesterol were found to be the main constituents of all the calculi. Calcium was found mainly in the centre and mucoprotein in the peripheral layers. The fine crystals of cholesterol were demonstrated in those biliary calculi which did not contain mucoprotein. It appeared that calcium might have acted as a cementing force rather than mucoprotein in this study.
对26颗混合感染性胆结石和2颗胆固醇结石进行了胆固醇、钙、脂肪和粘蛋白染色。发现钙和胆固醇是所有结石的主要成分。钙主要存在于结石中心，粘蛋白存在于外周层。在不含粘蛋白的胆石中发现了胆固醇细晶体。在本研究中，似乎钙起到了粘结作用，而非粘蛋白。
