Fig. 3From: Vasorelaxant effects of Angelica decursiva root on isolated rat aortic ringsConcentration-response curves to ADE on endothelium-intact aortic rings precontracted by PE (1 μM) in the presence or absence (not pre-treated control) of TEA (5 mM) (a), glibenclamide (10 μM) (b), or 4-AP (1 mM) (c). Values are expressed as mean ± SEM (n = 5–8, number of aortic rings). ** P < 0.01 vs. controlBack to article page
