Data describing the bioavailability of vascular-produced nitric oxide (NO) from ex vivo skeletal muscle conduit arteries from LZR and OZR at 7 (A), 10 (B), 13 (C), 17 (D), and 20 (E) wk of age. Data are presented as the slope of the NO level with increasing concentrations of methacholine-pooled arteries under control conditions and following pretreatment with either TEMPOL or Nω-nitro-l-arginine methyl ester (l-NAME). Data are presented as means ± SE; n = arteries from 8–10 animals in for OZR and n = arteries from 6–8 animals for LZR. *P < 0.05 vs. responses in LZR under control conditions; †P < 0.05 vs. responses in OZR under control conditions.
