[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.
