BK-induced vasorelaxation responses of preconstricted control coronary artery rings. Values are means ± SE. A: sulfaphenazole (Sulf) treatment alone tended to shift the dose-response curves to the left, but this effect was not significant (P = 0.450). B: however, in the presence of L-NAME, Sulf treatment decreased BK-induced relaxation of control LADs to 60%. C: Sulf treatment in the presence of L-NAME + Indo did not have an effect on BK-induced relaxation, since L-NAME + Indo + Sulf treatment resulted in 60% relaxation in both groups. D: relaxation in the presence of L-NAME + Indo + Sulf + KCl. *Significantly different from control.
