Summary Bilateral adrenalectomy combined with a sodium-deficient diet caused a time-dependent increase in plasma renin concentration in rats. Seventy-two hours after adrenalectomy the inhibitors of prostaglandin biosynthesis indomethacin and meclofenamate diminished the plasma renin concentration by about 50%. This effect was independent of the amount of renin released. Indomethacin and meclofenamate fully retained their ability to reduce the plasma renin concentration when the renal sympathetic nerves or the macula densa cells of the kidneys no longer contributed to renin release. It is concluded that in adrenalectomized rats renal prostaglandins affect the baroreceptor-mechanism in the afferent arterioles and thus enhance renin release.
