[Study of the glycosaminoglycan-glycosaminoglycan hydrolase system for evaluation of the healing dynamics in stomach and duodenal ulcer].

When studying the state of metabolism of the main substance of the connective tissue (glycosaminoglycan (GAG) and one of gag-hydrolases) in case of stomach and duodenal ulcers in patients under in-patient clinic conditions, it was shown that the amount of GAG in the urine approximately doubles in both groups in the state of exacerbation, and the given index reduces to the norm in the state of remission with a insignificant fluctuation of the b-glucuronidase level in the blood serum.
