in order to determine the role of growth hormone ( gh ) in the therapeutic effect of thyroxine ( t4 ) , we measured the content of serotonin ( 5-ht ) , 5-hydroxyindoleacetic acid ( 5-hiaa ) and substance p in discrete brain nuclei of neonatally-induced hypothyroid rats and in neonatally-induced hypothyroid rats subsequently maintained on bovine growth hormone ( b-gh ) injections .
