(a) Goblet cell number (means±s.e.m., n=6 rats per group) in individual bronchi determined from the apical, median and caudal lobes taken 60 min after challenge from rats treated with vehicle (0.5% ethanol; 0.2 ml i.t.) or capsaicin (30 μg kg−1 i.t.). The Mann–Whitney U-test revealed no difference between the treatment groups. (b) Perivascular edema assessed from apical, median and caudal lobes. Values (means±s.e.m. for six animals in each group) represent total edema values expressed as a percentage.
