Comparative concentration-response curves of sildenafil (full circles), acetylcholine (Ach, full squares), and sodium nitroprusside (SNP, full diamonds) in endothelium intact rat aortic rings precontracted by NA (3.10− 6 M). Each point is the mean ± SEM of 7–9 rats. * P < 0.001 vs 10− 10 M. ANOVA for repeated measures
