[Reparative processes in peptic ulcer (clinico-morphologic study)].

475 patients with stomach ulcer (1984-1993) were studied using various methods: endoscopical, immunological, biochemical, bacteriological and morphological. Morphology of exacerbation and type of reparative processes in normal scarring and torpid course of disease are presented. Under adequate regeneration there is an activation of immune system, first that of T-cell compartment. Torpid course is characterized by a grave regeneration disturbance and depression of the immune system. The interpretation of the so-called "red scar" is given: it reflects different stages of the epithelial regeneration, however in 4.8% of duodenal ulcers and in 11.2% of stomach ulcers it masks a torpid course. Helicobacter pylori has no influence on the reparative processes. Adequately chosen therapy improves and accelerates ulcer scarring.
