Effect of somatostatin on basal and stimulated pancreatic secretion in the rat.
The effect of linear somatostatin on pancreatic exocrine secretion in anaesthetized rats has been studied. Basal secretion of amylase was significantly inhibited by an infusion of 100 microgram/100 g/h somatostatin, but increased fourfold after a bolus injection of 50 microgram/100 g. CCK-stimulated enzyme and volume secretion were inhibited by somatostatin. Somatostatin did not influence secretin-stimulated bicarbonate concentration or rate of secretion in the dose range in which enzyme secretion was inhibited.
