ABSTRACT
Biopsies of stomach and duodenum different regions mucosa obtained from patients with gastroduodenitis (liquidators of consequences of accident in Chernobyl nuclear station--LCA CNS-- and control patients) were studied cultured in vitro. The following are the differences found. Mononuclear cells, differentiating into macrophages were exposed from control biopsies. Mononuclear cells exposed from LCA CNS biopsies formed rosette-like accumulations after mitotic dividing on a distance from the explant. Part of cells within the rosettes acquired processes and formed syncytial structure.

80 liquidators of Chernobyl disaster with aggravation of duodenal ulcer were examined, as well as a control group of 70 patients. In the group of liquidators some characteristic features were disclosed, namely peculiarities in the state of abdominal mucosa and clinical course of the disease. These data were obtained in the results of hematological, immunological and biochemical researches.
