Baseline characteristics of isolated airways
No significant differences (P>0.05) were found in the baseline characteristics of isolated airways used in this study. Passive sensitization induced significant AHR in C+ bronchi (P<0.05 vs. C-) and the maximal concentration of IL-5 was 12.21±2.79 fold greater in C+ than in C- tissues (P<0.001, e-Figure 1).
