SUMMARY The epidemiology and character of peptic ulcer has changed over the last 20 years, with only some of the change being due to the introduction of H2-receptor antagonists in the mid-1970s. There is evidence that duodenal ulcer was declining bef

Over the past few years, we have addressed some of the components that regulate human duodenal bicarbonate secretion (DBS) using a technique for the isolation of a 4-cm duodenal segment from gastric, pancreaticobiliary and distal intestinal secretion

The proximal duodenal epithelium secretes bicarbonate into an adherent mucus layer, thereby protecting the mucosa from injury by gastric acid and pepsin. While bicarbonate secretion is stimulated and inhibited by a number of agonists and antagonists,

Surface epithelial bicarbonate secretion protects the proximal duodenum from acid peptic injury. Cyclic adenosine monophosphate and calcium serve as intracellular mediators of intestinal transport. Experiments were performed to examine whether calciu

The duodenum, in contrast to the jejunum, actively secretes HCO3- at a high rate, a process that protects the mucosa from acid/peptic injury. Our purpose was to define the mechanisms involved in HCO3- transport by studying the acid-base transport pro

Gastric acid enters the proximal duodenum both as free and buffered H+. The procedures in this study were threefold: (a) to determine the pH threshold for duodenal mucosal bicarbonate secretion, iso-osmolar citric acid (pH 2.5-4.0; H+, 1.1 mmol) was

When the proximal duodenum of animals or humans is perfused with isoosmolar NaCl, bicarbonate enters the luminal effluent. In addition, duodenal bicarbonate output is stimulated by luminal acidification and prostaglandins of the E class. The hypothes
