Vascular responses to acetylcholine (A–D) and sodium nitroprusside (E,F) in the isolated femoral arteries of normotensive Wistar-Kyoto (WKY) and borderline hypertensive (BHR) rats before (A,C) and after (B,D) incubation with nitric oxide synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME, 300 μmol/l). ACh, acetylcholine; C7, seven-week controls; C9, nine-week controls; Post, post-stress; SNP, sodium nitroprusside. The results are mean ± SEM, n = 6–10/group. Symbols: ∗p < 0.05 vs. seven-week controls (C7) of the same phenotype,#p < 0.05 vs. stress of the same phenotype, xp < 0.05 vs. nine-week controls (C9) of the same phenotype.
