The activity of lysosomal exoglycosidases in serum of alcohol-dependent men supplemented with borage oil enriched with vitamin E.
The aim of this study was to determine the activity of the lysosomal exoglycosidases: alpha-mannosidase (MAN), alpha-fucosidase (FUC), and beta-glucuronidase (GLUCUR) in serum of alcohol-dependent men supplemented and not supplemented with borage oil enriched with vitamin E. Serum was collected from eight social drinkers and 16 alcohol-dependent men after a drinking period. The activity of exoglycosidases and the concentration of protein in serum were determined. The increase in specific activity of MAN and GLUCUR was significant in serum of alcohol-dependent men both not supplemented and supplemented with borage oil enriched with vitamin E, in comparison with the specific activity in serum of social drinkers. In serum of alcohol-dependent men treated with borage oil enriched with vitamin E, specific activity of MAN and GLUCUR fluctuated in comparison with alcohol-dependent men not supplemented. Specific activity of FUC in serum of alcohol-dependent men both not supplemented and supplemented with borage oil enriched with vitamin E showed a tendency to increase, in comparison with social drinkers. Specific activity of FUC had a tendency to decrease in serum of alcohol-dependent men supplemented with borage oil enriched with vitamin E, in comparison with alcohol-dependent men not supplemented. Thus, supplementation of alcohol-dependent men after a long-lasting drinking period with borage oil and vitamin E did not change the rate of catabolism of the oligosaccharide chains of glycoconjugates, as evaluated by serum activity of exoglycosidases.
