Decreased number of beta-adrenoceptors in cerebral cortex of hypothyroid rats
Abstract
The influence of thyroid hormone deficiency on beta-adrenoceptors in the rat cerebral cortex was investigated using the 3H-dihydroalprenolol binding assay. The maximal number of binding sites (Bmax) and the dissociation constants (KD) were determined in the brain tissue from euthyroid animals and from rats made hypothyroid by feeding 6-propyl-2-thiouracil. Hypothyroidism resulted in a 37% decrease in beta-adrenoceptor density (Bmax). The dissociation constants (KD) of both groups were not significantly different.
