[The physicochemical evaluation of the bile using infrared spectroscopy].
Native bile, inspissated bile, and cholesterol choleliths were examined by infrared spectroscopy. Model compounds spectra were compared with native bile spectra. The spectra were divided into 3 groups: with acid fragments or cholesterol groups predominating and intermediate group. The peak of 3620 cm-1, absent in normal human bile and liable to augment if acid fragment level reduced was detected. The authors suggest a technique of infrared spectroscopy permitting early detection of disordered physicochemical characteristics of the bile in the course of cholesterol cholelithiasis development.
