Figure 7: Combined therapy of PFD and BIBF exhibited enhanced efficacy in suppressing inflammation compared to single-drug treatment. (A) Representative images of HE staining in the crossed lung sections from each group of mice.(B) Statistic graph of Figure 7A. mRNA levels of Il-1β(C) , Il-6 (E) , and Tnf-α (G) of murine lung tissues. Protein concentration of IL-1β (D) , IL-6 (F) in BALF from mice. Bar values were shown as the mean ± SE. ∗ denotes the group compared to Si group. ∗P < 0.05, and ns indicates no significance. The range of P -values for ∗ and # is identical.
