Figure 5From: Vasorelaxant effect of Prunus yedoensis bark Inhibitory effect of MEPY (200 μg/ml) on the contraction induced by extracellular Ca 2+ addition (0.3–10 mM) in endothelium-denuded rat aortic rings pre-contracted by phenylephrine (PE, 1 μM) (A) or KCl (60 mM) (B) in Ca 2+ -free Krebs-Henseleit solution. Values are expressed as mean ± SEM (n = 5–7). * P < 0.05, ** P < 0.01 vs. control.Back to article page
