Adrenal dopamine β-hydroxylase induction in the young rat: influence of thyroid hormones

Abstract The adrenals of 14-day-old control and hypothyroid rats have been stimulated by insulin-induced hypoglycaemia, and the subsequent induction in dopamine β-hydroxylase (DBH) has been studied. In control rats, DBH induction was maximum 48 h after insulin administration. Hypothyroidism completely suppressed DBH induction.
