Changes in the content of fucoglycoproteins in the mucous membranes and walls of the stomach and small intestine of alcoholized rats under immobilization stress

Abstract

The article highlights the features of the metabolism of fucoglycoproteins in liver homogenates, the wall and mucous membrane of the stomach and small intestine in experimental models: alcoholic liver disease and prolonged alcoholization of rats under immobilization stress. Fucoglycoprotein metabolism was assessed for 90 days by the level of total fucose and fucosidase activity. To evaluate the implementation of the experiments, a biochemical analysis of markers of liver pathology was carried out. In the dynamics of experiments, there was an increase in transaminases and dyslipidemia in the blood serum of rats, as well as an increase in the level of corticosterone, especially in rats against the background of immobilization stress. In the exchange of fucose-containing glycoproteins in the blood serum, in the tissues of the liver, stomach and small intestine of experimental animals, multidirectional metabolic changes were monitored, namely, an increase in catabolism processes in the first days of observations in alcoholized rodents, which may be associated with the cytolytic effect of ethanol in the studied tissues. In these organs, the total amount of fucose is higher in the mucosa layer than in the organ wall. At the same time, in a series of experiments with immobilization stress against the background of ethanol administration, activation of anabolism of oligosaccharide fragments for the synthesis of fucoglycoproteins was noted in the second half of the experiment, associated with compensatory adaptive mechanisms.
