Popis: | After simultaneous administration of dexamethasone together with 6-hydroxydopamine or adrenergic neuronal blocking agents (alpha-methyldopa, reserpine, guanethidine) the dexamethasone-stimulated increase in renal excretion of p-aminohippurate (PAH) is distinctly diminished. The same is true for dopamine. This depressive effect could be proved by measurement of transport rates of PAH in renal cortical slices in vitro. The increase in kidney weight and in the protein content of kidney tissue in dexamethasone-treated rats is lower in rats simultaneously treated with adrenergic neuronal blocking agents of 6-hydroxydopamine. Adrenoceptor agonists and antagonists (pholedrine, orciprenaline, phentolamine, propranolol) are without influence on the dexamethasone-stimulated increase in PAH transport. |
