Fig. 1. (A) Effect of safranal in endothelium-intact aortic rings precontracted by using PE (10-6 M). The vasodilatory effect of safranal was expressed as a percentage of relaxation to maximum constriction induced by 10-6-M PE. Values are expressed as means ± SEMs. (B) Effect of the final amount of DMSO (%) in the organ chamber for each safranal concentration on aorta rings precontracted by using PE. DMSO was used as a control.
PE, phenylephrine; SEMs, standard errors of the mean; DMSO, dimethyl sulfoxide.
