[Role of the hypophyseo-adrenal system in regulating the acid-secreting function of the kidneys].
The experiments on male albino rats have shown that both stress and hydrocortisone elevate the urinary excretion of hydrogen ions in the form of titrated acids and ammonium ions. Desoxycorticosterone acetate (DOCSA) in intact rats, adrenal- and hypophysectomy lower ammonium ions excretion. Both stress and DOCSA increase the tubular sodium reabsorption, while hydrocortisone, adrenal- and hypophysectomy decrease it. A conclusion is made that both glucocorticoids and mineralocorticoids participate in the renal functional change under stress. It should be underlined that glucocorticoids stimulate the secretion while mineralocorticoids play the leading part in maintenance of sodium homeostasis.
