title: [Clinico-genetic problems of peptic ulcer in children].
abstract: Based on the results of 11200 endoscopies of the stomach and duodenum, the incidence of peptic ulcer in children was established with regard to the sex and site of ulcer. The authors view peptic ulcer as a heterogeneous disease in terms of the genealogical data and differences in proteolytic activity of gastric proteases in biological media.
