Acute hyperglycemia inhibits the growth hormone (GH) response to several stimuli including growth hormone-releasing hormone (GHRH), likely acting by stimulation of endogenous somatostatin release. The aim of our study was to verify whether arginine ([Arg] 30 g intravenously [IV] in 30 minutes), a well-known GH secretagogue likely acting via inhibition of(More)
OBJECTIVE To clarify the mechanism by which galanin, a 29-amino-acid peptide, increases GH secretion in man. DESIGN We studied the GH-releasing effect of this neurohormone (galanin, 15 micrograms/kg) infused over 60 minutes after 120 minutes of saline, following a previous GHRH bolus (GHRH 1 microgram/kg i.v. at 0 minutes, galanin infused from 120 to 180(More)
