title: Effect of antrectomy on small intestinal structure and function in the rat.
abstract: Antrectomy reduced the levels of circulating gastrin but did not change jejunal morphology. In vitro and in vivo absorption as well as the activity of some brush border enzymes were increased. The observed alterations are discussed on the basis of antrectomy-induced alterations in the release of gastrointestinal hormones, gastric and pancreatic secretion and gastric emptying.
