Interaction of nitrite and nitroprusside on regional blood flow. (A) Baseline and nitroprusside-induced absolute blood flow (dashed line) is enhanced globally following sodium nitrite infusion (solid line, P < 0·001, two-way anova with repeated measures), although (B) the degree of vasodilation above baseline is not changed. (C) The vasodilatory response to the maximal dose nitroprusside correlates highly with the response to the maximal nitrite dose (Pearson correlation, r = 0·75, P = 0·002). Solid line indicates the regression line, and dotted lines indicate 95% confidence limits.
