Quantitative Analysis of Elements in Gallstones and Biles from Chinese and Japanese Patients

摘要

The concentration of 26 elements in biles and gallstones from Chi-nese patients and the concentration of 10 elements from Japanese patients withgallstones were determined by inductively coupled plasma atomic emission spec-trometry (ICAP). Comparison of the level of elements between cholesterol andpigment gallstones revealed that Ca, Na, Fe, Cu, S, and Zn were higher inpigment gallstones than those in the cholesterol gallstones. Cholesterol stones aredivided into three subtypes: pure, mixed and combinated cholesterol stone.There were no significant difference among element contents. The levels of Ca,P, S, Li, and Ba in gallbladder biles were obviously higher in control groupthan in gallstone group. The element composition in gallbladder bile were similarto those in common bile duct bile. The former were 2～3 time high than the lat-ter.
