title: Influence of neonatal hypothyroidism on adrenal tyrosine hydroxylase activation in the young rat.
abstract: 1. Adrenal TH activation was elicited in young rats (aged 4, 6 and 14 days) by insulin hypoglycaemia. In the control rats, TH activation varied between 125 and 147% above basal values. 2. Neonatal hypothyroidism induced by PTU treatment impaired TH activation. Compensatory treatment with T3 to the PTU-treated young rats led to a return to control activation.
