Fig. 4From: Vasorelaxant effects of Angelica decursiva root on isolated rat aortic ringsInhibitory effect of ADE (100–400 μg/ml) on the contraction induced by extracellular Ca2+ in endothelium-denuded rat thoracic aorta rings pretreated by PE (1 μM) (a) or KCl (60 mM) (b) in the presence or absence (not pre-treated control) of ADE. Values are expressed as mean ± SEM (n = 5, number of aortic rings). * P < 0.05, ** P < 0.01 vs. controlBack to article page
