Somatostatin and peripheral blood flow in man. 1985

L Savi, and C Cardillo, and G Bombardieri

Somatostatin (SS), a physiological substance which inhibits secretion of GH, TSH, glucagon and insulin, was evaluated as a vasoactive agent. In normal and arteriopathic 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 observed. A reduction of heart rate was also observed. Some hypotheses about the mechanism with which SS acts upon peripheral circulation are discussed.

D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
D013004 Somatostatin A 14-amino acid peptide named for its ability to inhibit pituitary GROWTH HORMONE release, also called somatotropin release-inhibiting factor. It is expressed in the central and peripheral nervous systems, the gut, and other organs. SRIF can also inhibit the release of THYROID-STIMULATING HORMONE; PROLACTIN; INSULIN; and GLUCAGON besides acting as a neurotransmitter and neuromodulator. In a number of species including humans, there is an additional form of somatostatin, SRIF-28 with a 14-amino acid extension at the N-terminal.
