[Morphogenetic features of reparative regeneration of acetate gastric ulcer under chronic exposure to pesticide--copper sulphate]. 
Using morphologic, histochemical, histoenzymatic methods, the authors studied morphogenesis of acetate gastric ulcer in 40 rats subjected to chronic enteral intake of copper-containing pesticide-- copper sulphate.  Structural and metabolic basis for perverted regeneration of mucosa near the ulcer under continuous enteral exposure to toxic factor, dose dependence in chronization of acute gastric ulcer were established for the first time.
