CONTENT OF PROTEIN AND GLYCOPROTEINS, THEIR COMPONENTS IN THE ORAL FLUID IN CHILDREN WITH CHRONIC GASTRITIS, DUODENITIS

In the oral fluid of children with chronic gastritis, duodenitis there is the increased protein content (up to 7.33±0.43 g/l) against the background of the decreasing level of glycoproteins (up to 0.03±0.01 mg/ml). Coefficient of ratio protein / glycoproteins in the oral fluid is increased by a factor of 9510, which has shown the intensive decay of protein-carbohydrate complexes and the increasing content of the protein fragments. In the composition of glycoproteins there is the reduced amount of hexosamines (up to 0.23±0.01 mmol/l), against the background of the increasing sialic acids (up to 0.16±0.01 mmol/l) and fucose (up to 0.87±0.02 mmol/l). Coefficient of ratio of terminal and corpus monosaccharides in the glycoproteins of the oral fluid in patients with chronic gastritis, duodenitis is increased by a factor of 2.41 and 3.34, as compared to the same values in the control group of children, which significantly modifies the functional properties of the protein-carbohydrate complexes
