Concentration-relaxation curves for F1 in the isolated rat aortic rings. The F1-induced relaxation was studied on PE-precontracted endothelium-intact aortic ring preincubated with TEA or glibenclamide or 4-aminopyridine. Values are mean ± S.E.M (n = 6). *P < 0.05 compared with control (without blocker).
