Regulatory Mechanisms in Gastrointestinal Function includes a collection of contemporary topics in gastrointestinal research. The control of gastroduodenal electrolyte transport and the influence of drugs on bicarbonate secretion are reviewed in detail. The importance of the interactions between calcium and cyclic-AMP in intestinal secretion is emphasized in a comprehensive chapter that systematically addresses each link in the mechanisms that regulate chloride secretion. Other important topics included in the book are neural reflex modulation of intestinal epithelial transport, the influence of the microcirculation on intestinal secretion, and nitric oxide as a mediator of physiologic and pathophysiologic secretion. The expertise of the authors has resulted in a breadth of important contemporary topics covered in depth.
