[Analysis on infrared spectrum of human body gallstone with comparative method].
The infrared spectra (IRS) are measured for chemical composition of series gallstones. The infrared spectra (IRS) of the gallstone are compared with IRS of standard compound sample. The typical IRS are divided into 6 genera in component analysis of gallstone according to the principal characteristic peak: cholesterol, calcium bilirubin, calcium stearate, calcium carbonate, hydroxyl carbonate phosphatic rock and mixture. The gallstones are correlatively divided into 6 genera of gallstones or 2 genera-cholesterol and calcium salt gallstones according to whether containing calcium salt.
