Kangfuxin Oral Liquid Attenuates Bleomycin-Induced Pulmonary Fibrosis via the TGF-β1/Smad Pathway

Figure 1

KFXOL alleviates bleomycin (BLM)-induced pulmonary fibrosis in rats. (a) Pulmonary indexes were compared among different treatment groups 21 days after BLM administration. (b) Representative images of H&E staining in lung tissues from different groups; the thickness and number of alveoli differed significantly in (c) and (d). (e) Ashcroft scales of different groups were analyzed based on images of H&E staining. (f) Lung tissue sections were prepared and stained with Masson’s trichrome staining, and the relative collagen level of each group was quantified in (g) using ImageJ software. Data are presented as the mean ± SD; n = 8; ; .
