Effects of aldosterone and deoxycorticosterone on the urniary excretion of kallikrein and of prostaglandin E-like substance in the rat.

Deoxycorticosterone (5 mg) and aldosterone (0.25 mg), given to rats for 14 days, increased the urinary excretion of kallikrein and of prostaglandin E-like substance and produced polyuria, but affected neither sodium excretion nor blood pressure. These results suggest that interactions of mineralocorticoid hormones, kinins and of prostaglandins may be important in the maintenance of salt-water homeostasis.
