Figure 6: Combined PFD with BIBF exerted better effects on
improving lung function than the monotherapy. (A) Schematic diagram of
intragastric administration of PFD or BIBF, or PFD + BIBF in
silica-induced pulmonary fibrosis mice (n=9 per group). Bar charts
showing the indexes of lung function, including IC (B) , FVC(C) , FEV100 (D) , MMEF (E) , RI (F) ,
Cdyn, and Cchord (G) . 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.
