TABLE 1

Basal plasma glucose and insulin levels during continuous intravenous infusions of saline, 0.3, 0.9, or 1.5 nmol/kg/h acyl ghrelin (0–54 min) before an IVGTT

Infusion ratePlasma glucose (mg/dl)Plasma insulin (pM)
BaselineGhrelin steady state (t = 45–54 min)BaselineGhrelin steady state (t = 45–54 min)
Saline83.8 ± 4.686.9 ± 1.034.1 ± 4.836.5 ± 5.8
Ghrelin (0.3 nmol/kg/h)86.5 ± 2.496.7 ± 6.736.3 ± 4.830.4 ± 5.0
Ghrelin (0.9 nmol/kg/h)91.4 ± 2.193.5 ± 2.742.0 ± 6.636.1 ± 6.9
Ghrelin (1.5 nmol/kg/h)87.6 ± 1.691.5 ± 2.439.1 ± 5.825.6 ± 3.9
  • Data for baseline plasma glucose and insulin concentration were calculated as the average of the −15- and −1-min values. Data for plasma glucose and insulin at steady-state ghrelin concentration were calculated as the average of 45, 50, and 54 min values.
