FIGURE 2

Concentration-response curve to (A) GTN and (B) sensitivity to GTN in endothelium-intact aorta from control, GTN+placebo or GTN+serelaxin rats for 3 days. (C) Aortic superoxide production measured by lucigenin-enhanced chemiluminescence assay from control, GTN+placebo or GTN+serelaxin rats for 3 days. Values are expressed as mean ± SEM, n = 8–11 per group. P < 0.05, significantly different to control, #P < 0.05, significantly different to GTN+placebo (one-way ANOVA, Tukey’s test). Maximum relaxation (Rmax) values are shown in Table 2.
