[Lipid metabolism in cholelithiasis]

The results of studies of the blood and bile lipid metabolism in normal subjects and cholelithiasis patients and the findings of guinea pig experiments indicate that lipid levels decrease with age. The time course of the blood and bile lipids and the relationship thereof reflect the depression of cholesterol hydroxylation processes and reduction with age of cholic and deoxycholic acids synthesis and conjugation intensities in the patients with cholelithiasis, as well as a reduction of deoxycholic acid synthesis in normal subjects.
