March1 does not affect eosinophilic airway inflammation but induces neutrophilic inflammation in the airways: Total inflammatory cells in bronchoalveolar lavage (BAL) fluid were counted using hemocytometer and trypan blue exclusion method. Differential cell count in BAL: Differential cell count was performed on BAL cells adhered to slides and stained with HEMA-3. For each sample, 200–300 cells were counted under the microscope (40x), and their percentage was multiplied by the total cell count to extrapolate absolute differential count. ^∗ and ^∗∗∗ denote statistically significant; ^#p < 0.1 (trend); N.S.: non-ignificant. Data are presented as median (nonparametric data) and pooled from 5 independent experiments. N = 9–12/group.
