The results for each group are expressed as the means ± SEM. This experiment was started with 8 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% †Significant differences (P < 0.05) between PPE/vehicle on day 7 and PPE/vehicle on day 21
