“…Three blood samples were drawn at -1 0 , -5 , and 0 min before intravenous pulses of glucose (20 g) and arginine (2 g) were given. Additional samples were drawn 3,4,5,7,10,15,20,25,30,45,60,90, and 120 min after injection of the intravenous glucose pulse and 2, 3, 4, 5, 7, 10, 15, and 30 min after a subsequent intravenous arginine pulse. Basal glucose, insulin, and C-peptide values were calculated as the mean of the three preinjection values.…”
