[State of the mucus-producing apparatus of the stomach and duodenum in children with gastroduodenal pathology (lectin histochemistry].

Histochemical investigation of 228 mucosal biopsies from the stomach and duodenum of 57 children suffering from chronic gastroduodenitis and duodenal ulcer used the set of lectins PNA, WGA, SNA, LAL. In children with acute inflammation of the mucous membrane of the stomach antrum and duodenal bulb, redistribution of lectin receptors in the epithelium and mucus-producing glands was revealed to be similar to that in patients with duodenal ulcer. The above disorders of mucus production indicate the appearance of functional overloading of these structures and changes in the chemical composition of the mucus produced.
