Vasorelaxation in vitro. Line graphs show relaxation responses induced by acetylcholine in the absence (A) and presence (B) of L-NAME, and relaxations elicited by the NO donor nitroprusside (C), and the large conductance calcium-activated potassium channel opener NS-1619 (D) in the experimental groups; values are mean ± SEM, n = 10 for all groups; *P < 0.05, ANOVA for repeated measurements; ^†P < 0.05 NX groups compared with the Sham groups using two-way ANOVA for repeated measurements. Groups as in Figure 1.
