Concentration-response curves to (A) cumulative additions of hHK-1, EKA/B, EKC, EKD, SP, NKA and specific NK 1 ([Sar 9 ,Met(O 2 ) 11 ]SP) and NK 2 ([ β -Ala 8 ]-NKA (4-10)) receptor agonists on guinea pig trachea ( n = 6-12); (B) cumulative additions of hHK-1, EKA/B, EKC, SP and [Sar 9 ,Met(O 2 ) 11 ]SP on guinea pig main bronchi ( n = 6-7). 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.
