1. The effect of an intravenous infusion of insulin [2.5 units h-1 (m2 of body surface area)-1] on the rise in blood pressure and plasma aldosterone after intravenous angiotensin II (5, 10, and 20 ng min-1 kg-1) was investigated in six healthy, sodium-loaded men. 2. Serum insulin reached 96.8 +/- 18.1 mu-units/ml (control: 7.0 +/- 1.5 mu-units/ml) and serum potassium fell from 4.2 +/- 0.2 mmol/l to 3.6 +/- 0.2 mmol/l (P less than 0.005). 3. Hyperinsulinaemia increased (P less than 0.05) the secretion of aldosterone during the largest dose of angiotensin II (20 ng min-1 kg-1), but had no effect on the rise in blood pressure after angiotensin II.
