[Level of certain carbohydrate components in blood serum and urine of patients at extensive periods since suturing for perforated gastroduodenal ulcers].

The duration of gastric impairment before perforation as well as morphological features of sutured ulcer were shown to influence the protective functions of the gastric and duodenal mucosal membrane as shown by estimation of hexose, fucose and sialic acids in the blood serum and urine of 128 patients within later periods after suturing perforated gastroduodenal ulcers. Inhibition of the mucosal membrane protective functions in gastroduodenal tissues was increased with a longer disease period before perforation and with more distinct pathomorphological alterations of the perforated ulcer.
