Abstract

The effect of beta-adrenoceptor blockade by propranolol and practolol on submaximally pentagastrin-stimulated gastric acid secretion was studied in conscious non-vagotomized and in vagotomized gastric fistula dogs. Propranolol (0.5 mg/kg) intravenously augmented gastric acid output in vagotomized dogs, more after truncal and selective vagotomy than after parietal cell vagotomy. Vagally innervated dogs also showed an increase, but to a lesser degree and not statistically significant. The increase restored the acid output to preoperative levels in the vagotomized dogs. Practolol (1.0 mg/kg) intravenously resulted in a slight and insignificant increase in acid output in dogs with truncal vagotomy and had only a negligible effect in vagally innervated dogs and after selective and parietal cell vagotomy. It is concluded that propranolol augments pentagastrin-stimulated acid output in vagotomized dogs, and this augmentation was most pronounced in the totally vagotomized stomach. Practolol had minor influence on gastric acid secretion. This effect of the two beta-blocking agents indicates that beta 2-blockade is most important for the secretory augmentation. The restoration of postvagotomy acid secretion to preoperative levels suggest...Continue Reading

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
