Role of inducible nitric oxide synthase in postoperative intestinal smooth muscle dysfunction in rodents.

abstract：BACKGROUND/AIMS:The role of cholecystokinin (CCK) in the regulation of gastric acid secretion is still controversial. This study examined the effect of the CCK-A receptor antagonist loxiglumide (lox) on gastrin- or CCK-induced gastric acid secretion and meal-stimulated plasma gastrin levels in a placebo-controlled stud...
