Association between exaggerated responsiveness to thyrotrophin-releasing hormone and hypercholesterolaemia
Abstract:
Thyroid-function tests were performed on one hundred patients with suspected premyxoedema and the results compared with those in twenty age and sex matched controls. The increase in thyroid-stimulating hormone (T.S.H.) in response to thyrotrophin-releasing hormone (T.R.H.) was exaggerated in eighty-eight of the hundred patients with suspected premyxoedema. These included twenty-five with normal basal T.S.H. and sixty-three with a raised basal T.S.H. Serum-cholesterol concentration was significantly higher in those in whom premyxoedema was suspected than in the controls, even when patients presenting with degenerative arterial disease were excluded.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
