Abstract

Particle Induced X-ray Emission (PIXE) was used to analyse the elemental concentration of gallstones collected from different parts of south India. Cholesterol gallstones are predominant in north India, whereas pigment gallstones are predominant in south India. The black pigment gallstones are common in hemolytic anemia or in presence of infected bile. PIXE has revealed the elemental profile in each sample. The experimental subjects of the different groups displayed significant variation in their levels of certain trace elements such as copper, zinc, and iron. The concentration of copper was found to be predominant in pigment gallstones investigated in the present study.
