    Abstract:
    The effects of infusion of a large amount of aldosterone into the renal artery of isolated perfused hog kidney on the release of renin, prostaglandins (PG) and kinin and the excretion of urinary kallikrein were investigated. Infusion of aldosterone at a rate of 100 ng/min (100 to 800 ng/ml of perfusate) resulted in significant releases of renin, PG (PGE2 , 6-0-PGF1 alpha), and kinin and increase in urinary kallikrein. Infusion of aldosterone and an inhibitor of kallikrein, aprotinin, decreased the releases of renin, PG and kinin and infusion of aldosterone with indomethacin decreased the release of PG but increased that of kinin and urinary kallikrein without significant change in renin releases. These findings suggest that the release of renin by aldosterone may result from synergic effects of renal PG and the kallikrein -kinin system.
