摘要
The effect of a single injection of 10-mu-g chicken GH on circulating thyroid hormones as well as in vitro liver 5'-monodeiodination (5'-D) activity was studied in posthatch chicks submitted to different feeding conditions. One group was normally fed after hatching, a second group was only fed after three days and a third group was food deprived after 2 days of feeding. Combination of all results indicates that the start of food intake abolishes the stimulatory effect of a GH injection on circulating T3 and liver 5'-D activity. Food deprivation after a period of food intake restores the GH effect on plasma T3 but not on liver 5'-D.
