Concentration response curves for acetylcholine in (A) WKY mesenteric rings, (B) SHR mesenteric rings, (C) WKY aortic rings, and (D) SHR aortic rings, with intact or denuded endothelium following short-term incubation with 0.5 mmol·l−1 L-phe. Data represent mean ± SEM n = 6 animals (in triplicate/animal) for mesenteric arteries and aortic rings (*p < 0.05 and *** p < 0.001 for the whole curve). Table (E) shows EC50 values (nmol·l−1) comparing saline control with L-phe treatment for each study. Data represent mean EC50 values ± SEM, n = 6 independent experiments (**p < 0.01 and ***p < 0.001). Ach = acetylcholine; EC50 = effective concentration for 50% maximal response; other abbreviations as in Figure 1.
