[Functional mesenchymal indices in peptic ulcer]

Altogether 84 patients with duodenal ulcer were examined for a study of mesenchyma function. The blood level of oxyproline, the system of histamine-histaminase-histaminopexic index, and the level of serotonin before and after treatment were studied. The level of IgG, A, M and the amount of T- and B-lymphocytes were defined for assessment of the immune system. The basal level of oxyproline in patients with peptic ulcer was lowered and returned almost to normal after treatment. These changes as well as changes of biogenic amines and immune system indicate the presence of shifts in the collagen system in peptic ulcer.
