Endothelial function of mesenteric resistance arteries was not impaired by a high-salt diet or 2-kidney, 1-clip (2K1C) hypertension. A and B: mean ± SD % relaxation in response to acetylcholine (A) or sodium nitroprusside (SNP) (B) of mesenteric resistance arteries from sham-operated or 2K1C mice fed 0.1% or 4.0% NaCl (n = 6 or 7 per group). C and D: box plot diagrams of EC₅₀ (C) and E_max (D) of acetylcholine vasodilatory responses. A 2-way ANOVA revealed no significant differences between groups.
