Structural, functional and hypertensive effects of 19-oxo-11-deoxycorticosterone acetate (19-oxo-DOCA) in the rat

Mononephrectomized rats were given 1% NaCl solution to drink; half of them received 1 mg/day of 19-oxo-11 deoxycorticosterone acetate (19-oxo-DOCA) in sesame oil subcutaneously and half received only the oil for a period of four weeks. The steroid had no effect upon saline intake, systolic blood pressure, growth or the size of adrenals, hearts or kidneys, although it did produce hypernatremia and hypokalemia. The discrepancy between a demonstrable mineralocorticoid effect without blood pressure elevation awaits elucidation.
