title: Effect of intravenous infusion of somatostatin on gastric, pancreatic and biliary secretion in the rat.
abstract: The effect of somatostatin (GH-RIH) on gastric, pancreatic and biliary secretion was examined in the anesthetized rats. Intravenous infusion of the hormone, in graded doses ranging from 1 to 16 microgram/kg/hr, produced a dose dependent inhibition of pentagastrin, 1.5 microgram/kg/hr, induced acid secretion, reaching about 54% of control level at the dose of 16 microgram/kg/hr. Somatostatin, 4, 16 and 64 microgram/kg/hr, inhibited the pancreatic juice volume stimulated by intravenous injection of secretin, 1 u/kg, as a bolus. Somatostastin, 2, 8, 32 and 128 microgram/kg/30 min, did not change the bile flow rate in control period. Somatostatin may play a physiological role in the regulation of the secretory process of the stomach and pancreas.
