Insulin significantly and dose dependently inhibited the vasoconstriction induced by NE (10(-8) M for the artery and 10(-7) M for the vein) at greater than or equal to 1.2 mU/ml for both the artery and vein and the vasoconstriction induced by ANG II (3 x 10(-10) M for the artery and 3 x 10(-9) M for the vein) at greater than or equal to 1.2 mU/ml for the artery and greater than or equal to 12 mU/ml for the vein.
