[Gas-chromatographic analysis of hypercholestanol in the bile and its role in the pathogenesis of cholelithiasis].

The cholestanol/cholesterol ratio in the bladder and liver bile was estimated by capillary gas-liquid chromatography in patients with dyskinesia of the gallbladder, chronic acalculous cholecystitis, and chronic calculous cholecystitis. Cholesterol biliary calculi and their surface and intermediate layers and the core were examined either. The authors came to a conclusion that cholestanol/cholesterol ratio in the bladder and liver bile reflected the progress of liver cholesterol metabolism starting from the early stages of cholelithiasis to the formation of cholesterol biliary calculi. Therefore hypercholestanolcholia should be considered as an indicator of the risk of cholesterol biliary calculi development.

[Nervous tissue glycoproteins normally and under the action of oxygen under pressure].

Salt-soluble proteins of great hemispheres of rats, intact and those subjected to the effect of hyperbarooxigenation, were separated by DEAE-cellulose chromatography into 10 heterogenous fractions, each of them containing 5-12 subfractions. The content of glucosamine and sialic acid was determined in each of the isolated fractions. Changes in the degree of heterogeneity and in total content of protein in the fractions as well as variations in the content of carbohydrate components in the chromatographic fractions are observed under the effect of hyperoxia.
