Effect of DATS on lung injury in of mice. Five mice from each group were euthanized at days 2, 4, and 6 post-infection, and their lungs were harvested and weighed. Abbreviations are the same as those in Fig. 4. Significant difference was determined by comparing the data to those of H9N2 AIV-infected group (*p < 0.05, **p < 0.01). a Wet lung weight to body weight ratios. b Viral loads in the lungs determined by TCID50 assay on MDCK cells. c Expression levels of H9N2 AIV M gene determined by real-time PCR. Fold change was calculated using the 2^−ΔΔCt method
