[The morphometric and immunohistochemical indices of the gastric and duodenal mucosa in the dynamic treatment of erosive gastroduodenitis in those who worked in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station in the follow-up period].

62 Chernobyl wreckers with erosive gastroduodenitis (50 cases) and ulcer (12 cases) were admitted to hospital where they received standard drugs and local He-Ne laser treatment of erosions and ulcer located in the antral stomach and duodenal bulb. Histological, bacterioscopic, morphometric and immunohistochemical examinations have identified chronic inflammation and disturbance of local immunity. After treatment epithelialization of erosions was not accompanied by normalization of morphometric and immunohistochemical parameters. This suggests a high risk of recurrences.
