FIGURE 2

Nitric oxide synthase (NOS) activity in the aorta (A), left heart ventricle (B), hypothalamus (C) and brainstem (D) of normotensive Wistar-Kyoto (WKY) and borderline hypertensive (BHR) rats in 7-week controls (C7, white bar), stress (black bar), 9-week controls (C9, gray bar) and post-stress (Post, strip bar). In the aorta, the main effect of stress vs. age-matched controls (C7) was significant (see Results section for details). The results are mean ± SEM, n = 6–8/group. Symbols: p < 0.05 vs. 7-week controls (C7) of the same phenotype, #p < 0.05 vs. stress of the same phenotype, xp < 0.05 vs. 9-week controls (C9) of the same phenotype, +p < 0.05 vs. the same WKY group.
