title: [Insulin-poietic effect of pentagastrin after beta-adrenergic block in the anesthesized dog].
abstract: Infusion of pentagastrin (5-G) into the femoral vein of anaesthesized dogs, in doses of 0.20 microgram/kg/min for 30 minutes, causes a prompt and significant increase in plasma IRI. The insulin-secretory effect of the peptide was not affected by 0.5 mg/kg i.v. of propranolol (a beta-adrenergic blocking agent) or by 1.3 mg/kg i.v. of practolol (a selective beta1-adrenergic blocking agent). These results show that the action of 5-G on the pancreatic beta-cells could be not related to the beta-adrenergic system.
