Schematic diagram of animal experimental protocol. Mice were preconditioned with 0.5 ppm O3 or filtered air for 1 h at day 1, 3, 5 and 7. On day 10 (48 h after the last preconditioning), mice were further stimulated with 2.0 ppm O3 or filtered air for 3 h. On day 11, biological measurements including differential BAL cell counting, lung histological evaluation, epithelial permeability and lung oxidative stress were performed
