Bilateral oophorectomy and plasma renin substrate concentration.
Plasma renin substrate concentration was studied in 11 premenopausal women subjected to bilateral oophorectomy and hysterectomy. Preoperative plasma renin substrate concentration was 1573 +/- 477 ng angiotensin I/ml (mean +/- SD). Plasma renin substrate concentration did not change significantly after operation (1632 +/- 459 ng angiotensin I/ml) or after 3 months of postoperative estradiol valerate treatment (2 mg/day) (1762 +2- 467 ng angiotensin I/ml). It is concluded that non-pregnant levels of endogenous estrogens are of no significance in the regulation of plasma renin substrate.
