Noradrenergic and dopaminergic modulation of thyrotropin secretion in the rat.

Abstract

Noradrenergic and dopaminergic regulation of thyrotropin (TSH) secretion was investigated in adult male Wistar rats. TSH secretion displayed a circadian variation with peak serum TSH levels at 10.00 h. The alpha 2-adrenoceptor agonist, clonidine (250 micrograms/kg, i.p.), was found to cause an enhancement of serum TSH levels at 10.00 h (160 +/- 10% of… (More)
