[Ultrastructure of mucosal cells in different variants of the effects of acid production].

The work is devoted to the search of the more rational method for acid production correction. Three different types of operations were performed on 6 dogs with this aim: resection of the 2/3 part of the stomach with the Bilrot-P method, proximal selective vagotomy, and adequate correction of acid production by the method of V. Naumov. Various conditions were created to form "feed-backs", which provide the trophic structure of the stomach mucous coat cells. The ultrastructure of the stomach mucous coat cells was examined 6 months after the date of operation. Those dogs that were operated with the preservation of the sphincter and the part of the gastrin producing area of the antrum did not have any great changes in the cell ultrastructure.
