Effectiveness of saline and Y-27632 inhalations to reduce basal airway responsiveness and airway (hyper)responsiveness after the EAR and the LAR for histamine (A) and PGF_2α (B). Data are expressed as the PC₁₀₀ ratio post/pre saline or Y-27632 inhalation. Data represent means ± s.e.mean of 5 (histamine) and 7 (PGF_2α) animals. *P < 0.05 **P < 0.01 compared to basal effectiveness.
