Effect of an Ethanol Extract of Scutellaria baicalensis on Relaxation in Corpus Cavernosum Smooth Muscle
(a) Comparison of ESB-induced cavernous smooth muscle relaxation in high K-contracted and PE-precontracted rabbit cavernosum smooth muscle strips. The mean value ± S.E. are shown. KCl 45 mM (), KCl + ESB (), PE + ESB (). * versus PE + ESB. (b) Effects of K+ channel blockade on ESB-induced rabbit cavernous smooth muscle relaxation. TEA, tetraethylammonium; gliben, glibenclamide. (c) Effect of K+-selective inhibitor on ESB-induced rabbit cavernous smooth muscle relaxation. Mean values ± S.E. () is shown. * versus vehicle. (d) Effect of 4-aminopyridine (4-AP) on ESB-induced rabbit cavernous smooth muscle relaxation. Mean values ± S.E. () are shown.
