Carotid artery endothelium-dependent dilation (EDD) to increasing doses of acetylcholine (A) and peak EDD (B) in the absence and presence of the nitric oxide (NO) synthase inhibitor L-NAME (NG-nitro-L-arginine methyl ester) in young (6 mo) control (YC) and old (27 mo) control (OC) mice and old mice supplemented with sodium nitrite for 8 weeks (ON). Carotid artery endothelium-independent dilation to increasing doses of the NO donor sodium nitroprusside (SNP) (C) and peak dilation to SNP (D). N=9–10/group. All data are mean±SEM. *p<0.05 vs. young control.
