【Abstract】 The insoluble remains of brown and mixed pigmented gallstones, which were dissolved with chloroform, ethanol, and ether, were studied by scanning electron microscopy(SEM). The ultrastructure of the insoluble remains of pigmented stone had holes connected by membranous materials. There were large numbers of salts particles sandwitched between two membranes. The ultrastructure of the insoluble materials of mixed stone whose cross section looks like tree rings with holes connected by floc materials in which salts were embedded. The chemical elements in gallstones were investigated by energy dispersive X ray microanalysis and inductively coupled plasma atomic emission spectrometry. The relationship between the metallic elements and the structure and the formation of gallstones was discussed.更多还原
