[Balance of carbohydrate-containing biopolymers in the large intestine and mechanism of its impairments in ulcerous disease].

Excretion of carbohydrate-containing components of glycoproteins with feces was studied in patients with ulcerous disease, chronic gastritis, with cancer of stomach and in healthy persons. Content of glycoproteins, especially of fucoglycoproteins, was decreased in intestinal mucous during an acute period of the ulcerous disease. The same phenomenon was observed in epithelium of a distal part of small intestine. Remissions were accompanied by an increase in content of fucoglycoproteins in mucus and epithelium cells. These alterations in balance of glycoproteins were not found in other investigated impairments of the gastro-duodenal system.
