title: Effect of mammalian growth hormone on amino nitrogen mobilization in the eel.
abstract: Hypophysectomy decreased plasma amino nitrogen (PAN) levels of Japanese eels. In contrast, administration of bovine or ovine growth hormone (GH; 2 micrograms/g) produced a delayed increase in PAN levels of both intact and hypophysectomized eels 48 hr after GH injection. The minimum dose of GH required to elevate PAN levels was found to be 0.1-1 micrograms/g body wt. The fact that GH treatment also increased PAN of hepatectomized eels indicates that the increased PAN was at least partly caused by the increased mobilization of amino nitrogen from body protein. GH also increased plasma free fatty acid content of intact and hypophysectomized eels 48 hr after GH injection in one experiment of the present study, but this effect was not reproducible in other experiments. No effect of GH administration was observed either in plasma glucose and lipid of intact and hypophysectomized eels 48 hr after the injection.
