RESUMO
The comparative evaluation of qualitative and quantitative composition of glycoproteins of gastric and duodenal wall surface layer of protective mucus in the normal, at the modeling of ulcers in rats and at the introduction to animals with ulcerative lesions of fenugreek extract carried out. It was shown in control (normally) the general level of glycosylation of glycoproteins gastric mucus is 1.7 times more than the duodenum. Under acute stress model ulceration in the stomach mucus decrease in hexosamine (1.4 times), galactose (2.2 times), fucose (1.3-fold) and an increase in NANA (3.6 times) observed. Under cysteamine model ulceration in duodenal mucus increase galactose (2.7 times), NANA (2.4 times), fucose (1.8-fold) but significant decrease in the amount of hexosamines 3 times compared to the control occurred. It was proved the protective effect of fenugreek extract to the wall surface mucus of the stomach and duodenum mucosa under conditions modeling ulceration in rats.
