1 GH did not influence circulating levels of total IGF-I, C-peptide, insulin or glucose, but caused a further increase in NEFA, glycerol and 3-OH-butyrate levels, indicating enhanced lipolysis and ketogenesis. 3-Hydroxybutyric Acid growth hormone 1 Homo sapiens
2 This effect of GH was much more pronounced during IGF-I: NEFA rose from 702 +/- 267 (saline) and 885 +/- 236 (IGF-I) to 963 +/- 215 (saline) (p < 0.05) and 1815 +/- 586 mumol/l (IGF-I) (p < 0.02), respectively; after 5 h, 3-OH-butyrate rose from 242 +/- 234 (saline) and 340 +/- 280 (IGF-I) to 678 +/- 638 (saline) (p < 0.02) and 1115 +/- 578 mumol/l (IGF-I) (p < 0.02) respectively. 3-Hydroxybutyric Acid growth hormone 1 Homo sapiens
3 After injection of GH, forearm uptake of 3-OH-butyrate was markedly elevated only in the subjects treated with IGF-I: from 44 +/- 195 to 300 +/- 370 after 20 min (p < 0.03) and to 287 +/- 91 nmol.100 ml-1. 3-Hydroxybutyric Acid growth hormone 1 Homo sapiens
