[The content of cholylglycine in the blood serum in cholelithiasis during treatment with litholytic preparations of bile acids].

Liver function has been assessed on the basis of radioimmunoassays of the primary conjugated cholic acid, cholylglycine, in the blood sera of cholelithiasis patients treated with cheno- and ursodeoxycholic acid drugs for a long time. The findings indicate that the blood serum cholylglycine levels may be regarded, among other things, as a prognostic criterion of the efficacy of cholelithiasis therapy with bile acid preparations for litholysis.
