Figure 4: (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.
