The number of total cells, neutrophils, eosinophils, lymphocytes and macrophages in the BALF in control animals (C, n = 10), asthmatic mouse model (A, n = 10), asthmatic mice with hydrogen gas inhalation (AH, n = 10) and control animals with hydrogen gas inhalation (H, n = 10). Statistical comparison between groups was performed using analysis of variance followed by Tukey’s test. * P < 0.05, ** P < 0.01, *** P < 0.001 compared to the control group, # P < 0.05, ## P < 0.01 compared to the asthma group
