Abstract

Antral exclusion was performed in seven adult male Sprague-Dawley rats, which were killed 10 weeks later. Fasting serum gastrin concentrations were almost four times higher than in unoperated controls. There was a slight increase in the thickness of the gastric mucosa, but quantitative electron microscopy showed no significant changes in parietal cells.
