Catholic University of the Sacred Heart, Department of Internal Medicine, Rome, Italy Somatostatin (SS), a physiological substance which inhibits secretion of GH, TSH, glucagon and insulin, was evaluated as a vasoactive agent. In normal and arteriopatic subjects SS was administered intravenously by bolus for 3 minutes and by infusion for 30 minutes. Rheography and plethysmography of lower limbs were performed before, during and after somatostatin administration. A marked improvement of blood flow, provoked by somatostatin, was ob served. A reduction of heart rate was also observed. Some hypotheses about the mechanism with which SS acts upon peripheral circulation are discussed.
