Histological and electron-microscopic observations on the mucosa of pediculated duodenal wall graft transplanted to the stomach in Wistar rats

摘要

Conclusions The formation of gastric metaplasia in the duodenal mucosa may be related to a change of the microenvironment around the tissues, and duode- nal mucosa may differentiate into gastric epithelium by the decrease of pH value. Objective To study the mechanism of gastric metaplasia in duodenum through the transplantation of a flap of duodenal wall with vascular pedicel to the stomach. Mehtods The pediculated duodenal wall flaps of Wistar rats were transplanted to their stomachs.
