to evaluate the potassium-aldosterone axis in chronic renal insufficiency , the plasma concentration of aldosterone was measured before and after a 50-meq potassium challenge in dogs with intact kidneys ( glomerular filtration rate 52 +/- 3.1 ml/min ) and in dogs with one remnant kidney ( glomerular filtration rate 16.1 +/- 2.1 ml/min ) .
