[Role of cytokines in the metabolism of the extracellular matrix carbohydrate-protein components in patients of various ages with gastroduodenal ulcer].

The results of the study made in 43 patients with gastroduodenal ulcer have shown an increase in the production of proinflammatory cytokines (interleukin-1 beta, the tumor necrosis factor-alpha) and a decrease in the blood serum content of the transforming growth factor-beta, which events come to favour degradation processes in collagen and fucoglycoproteins with a concomitant increase in free oxyproline, serum protein-unbound fucose against the background of a suppressed synthesis of the extracellular matrix carbohydrate-protein components as evidenced by the serum diminished concentrations of protein-bound oxyproline and fucose, hexuronic acids, and hexosamines.
