Figure 7.
Role of potassium channels in SF-induced relaxation of aortic rings. Endothelium-intact rings were incubated with cumulative doses of SF in the absence (Salvia plus vehicle; filled circles) or presence of (A) 10 µM of Glibenclamide (Glib + Salvia; squares), or (B) Tetraethylammonium (100 µM) (TEA + Salvia; triangles). n = 6 or 5 for glibenclamide or TEA experiments, respectively. In both cases, no difference was noted between inhibitor treated and vehicle administered curves; p > 0.05 for Salvia alone versus either Glib + Salvia or Salvia + TEA.
