Figure 4

Effects of inhibitor of K+ channels on vasorelaxant response induced by oligopeptides on endothelium-denuded aortic rings pre-contracted with PE (1 μM) in presence of (a) TEA (5 mM, ) and BaCl2 (1 mM, ) and (b) 4-AP (1 mM, ) and Glib (10 μM, ). The data are expressed as mean ± SEM, * , compared with control (−Endo).
