[The role of biliary dyskinesia in the mechanism of the damage to the protective properties of the mucosal barrier in peptic ulcer].

Mucous barrier resistance was studied in 232 duodenal ulcer patients with signs of exacerbation as shown by PAS-positive substances and acid mucopolysaccharides in antral mucosa of the stomach and duodenum as well as by gastric juice levels of gastromucoproteins, fucose and sialic acids. In addition, measurements were performed of biliary motility. The tests indicated that half of the ulcer patients developed biliary dyskinesia manifesting as hyperkinesia or hypokinesia. The resultant decrease in gastric mucins requires individual correction.
