Figure 2: PFD and BIBF could attenuate lung inflammation in silicosis mice. (A) Representative images of HE staining in the crossed lung sections from each group of mice. Statistic graph was indicated on the right. (B) mRNA levels of Il-1β of murine lung tissues. (C) protein concentration of IL-1β in BALF from mice. (D) mRNA levels of Il-6 of murine lung tissues.(E) Protein concentration of IL-6 in BALF from mice.(F) mRNA levels of Tnf-α of murine lung tissues. 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.
