Regional differences in gallstone have been described in India. The elemental composition of gallstones from southern India has been reported. Cholesterol gallstones are rare in the southern parts of the Indian subcontinent.
was to determine any differences in the elemental composition of cholesterol gallstones from North and South India.
Fifteen samples of cholesterol gallstones from north and south India were subjected to Fourier Transform Infrared spectroscopy (FTIR) and Proton Induced X-ray Emission (PIXE).
FTIR showed the south Indian stones to be rich in cholesterol while the north Indian stones had in addition calcium carbonate, phosphate and palmitate. Concentrations of calcium, phosphorus and potassium were high in north Indian cholesterol gallstone while zinc, manganese, copper, chromium, iron and bromine were found in higher concentrations in south Indian cholesterol gallstone.
Distinct differences in elemental constituents have been observed in cholesterol gallstones from north and south India.
