Treatment with NEt-4IB improves the PPE-induced proteinase/anti-proteinase imbalance and impairment of anti-oxidant activity. a Experimental protocol. b MMP-9/TIMP-2 ratio in BAL fluid on day 4. c Anti-oxidant activity measured by the BAP test in BAL fluid (a) and in serum (b) on day 1. The results for each group are expressed as the means ± SEM. This experiment was started with 10 mice in each group, and no mice were died during the experimental period. * Significant differences (P < 0.05) between PBS/vehicle and PPE/vehicle. # Significant differences (P < 0.05) between PPE/vehicle and PPE/NEt-4IB 0.015%.
