Selective reduction of adrenal medulla response to angiotensin induced by suppression of renin-angiotensin.

Angiotensin II (AII) induced an increase of adrenaline (A) release from rat adrenal glands in vitro. The response of the adrenal glands was completely abolished 22--24 h after bilateral nephrectomy. Adrenal glands from DOCA-salt-treated rats did not respond to AII as well, whereas adrenal glands from rats treated with furosemide and a low salt diet retained this response.

Rat uterus renin-like activity: effect of stimuli and hormones.

1 The characteristics of renin-like activity in rat uterus were studied. The optimum temperature was 50 degrees C and optimum pH 4.0.
