Abstract

Laser-induced fluorescence spectra of gallstone samples from three different age group was analysed in the visible region. The gallstones were obtained from patients at Aizawl Civil Hospital, Mizoram, Northeast India, who had undergone surgery. Subjects included both adults and children patients so that the age group was classified as group A consisting of 30 years, group B consiting of 39 years, and group C consisting of 60 years of age. The stones were washed with deionized water and dried. The absorption spectra for all the mixed type gallstone samples show only one broad band in the visible region that lies in the 400-800 nm region with λmax at about 450 nm. Significant changes were observed when different solvents were used. Our present understanding is that the most important mechanism whereby cholesterol is held in solution in the bile is that it is taken into miceller solution in combination with phospholipids and bile salts.
