Values are averages of 6 blood samples taken at hourly intervals except for GH where samples were collected every 15 min during the last 6 hours of the infusion. Values are means ± standard error of the mean (SEM). a,b,c Values within the same row with different superscripts are significantly different (P < 0.05) | ||||
