FBF variations in response to L-NMMA infusion into the brachial artery in patients and controls.
L-NMMA (0.5, 0.8, and 1 μg/min) was infused into the brachial artery, and FBF variations expressed in milliliters per minute per 100 milliliters were recorded using VOP. ANOVA detected no significant difference between the 2 groups. ▵, patients; ▪, controls.
