(A) Cumulative concentration-response curves of hHK-1 on human bronchi ( n = 5-12) in the absence (control) and presence of NK 1 , NK 2 or NK 3 receptor antagonists SR 140333, SR 48968 or SR 142801 (10 -7 M). (B) Cumulative concentration-response curves of hHK-1, EKA/B, EKC and EKD on human bronchi (n = 3). Experiments were performed in the presence of phosphoramidon (10-6 M). Values are expressed in percentage (mean ± s.e.m.) of maximal contraction obtained with ACh 3 mM.
