Analysis of Indian pigment gallstones
Abstract
Particle induced X-ray emission and particle induced γ-ray emission spectroscopic techniques have been carried out to analyse the elemental concentrations of human pigment gallstone samples from eastern region (Orissa) and southern region (Chennai) of India. It was observed that 18 minor/trace elements namely Na, Mg, Al, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br and Pb were present in the pigment gallstone samples of both the regions. Our study reveals that average concentration of all elements except Ni in south Indian pigment gallstone samples is higher than that of corresponding values in east Indian pigment gallstone samples whereas elements like Al, P, S, Cl and V did not show much variation between these two regions. Fourier transform infra-red analysis was carried out to identify the functional groups and the classification of the pigment type gallstones of both the regions. The thermal behaviour of pigment gallstones was carried out by thermogravimetry-derivative thermogravimetry analysis.
