Figure 3: Inhibitory effect of EOK (0.3 mg/mL) on the contraction induced by extracellular Ca2+ addition (0.3–10 mM) in rat aortic rings precontracted with phenylephrine (PE, 1 μM) (a) or KCl (60 mM) (b) in Ca2+-free Krebs-Henseleit solution and vasorelaxant responses induced by EOK (0.01–0.8 mg/mL) in rat aortic rings precontracted with PE (1 μM) in the presence or absence of nifedipine (10 μM). Values are expressed as mean ± SEM ( ). * versus control. # and ## versus absence of nifedipine group.
