Effects of the glucocorticoid antagonist RU486 in spontaneously hypertensive and Sprague Dawley rats
Publikováno v:
Journal of Endocrinological Investigation. 18:833-839
The effect of a low dose of the gluco-corticoid receptor antagonist, RU486, was tested in spontaneously hypertensive (SHR) and in Sprague Dawley (SD) rats. In SD rats, RU486 (50 micrograms/day, 18 days) significantly increased growth rate and thymus

Eight healthy volunteers were entered into a randomised, open crossover study to investigate the in vivo behaviour of an enteric coated starch capsule. A radiolabelled preparation was administered to each volunteer on two occasions separated by 7 day

We have previously reported that benzodiazepines inhibit microsomal steroid hydroxylases. We have now studied their effects at much lower drug concentrations and have also addressed the suggestion that benzodiazepines alter cellular calcium metabolis

18-Hydroxycortisol has been suggested as a marker compound for a transitional zone between the adrenocortical zonae glomerulosa and fasciculata. The control of secretion of 18-hydroxycortisol has been compared with those of cortisol and aldosterone i

Angiotensin II (AII) stimulation of steroidogenesis is known to be associated with depolarization of the adrenocortical cell membrane. In these cells, membrane permeability to potassium ions governs electrical potential. The effects of All on the rat

Fast and slow K+ efflux components, independently regulated by angiotensin II (AII), have been identified in bovine adrenocortical cells. We have further investigated the role of potassium in the control of aldosterone synthesis in two ways. Firstly,

Glucocorticoid receptor binding was compared in liver cytosol preparations from spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats using homologous displacement of [3H]dexamethasone. At 5 degrees C, there was no difference in receptor

Previous studies have indicated that peripheral benzodiazepine receptor (PBR) ligands inhibit aldosterone secretion in isolated adrenal zona glomerulosa cells although positive responses have been demonstrated in other steroidogenic tissues. In the p

Carbenoxolone potentiates the mineralocorticoid activity of endogenous glucocorticoid hormones by inhibiting the enzyme 11 beta-hydroxysteroid dehydrogenase, which converts cortisol and corticosterone to inactive 11-oxo-derivatives. We addressed the
