Fig. 2. Relaxation effect of safranal in endothelium-intact aortic rings in the presence of indomethacin (10-5 M). Aortic rings were incubated with indomethacin for 20 minutes, after which the aortic rings were contracted by using 10-6-M PE. The vasorelaxant effect of safranal was then examined. Values are expressed as means ± SEM (Tukey-Kramer).
PE, phenylephrine; SEM, standard error of the mean.
