Effects of rPTX3 treatment on histopathological changes. Representative pictures of H&E staining (a), PAS staining (b), and Masson staining (c). The bar charts demonstrate the differences between inflammatory scores (d), and PAS scores (e). Representative western blot pictures of Collagen I in lung tissues, and protein expressions of Collagen I were quantified based on the density of the bands (f). Data are shown as the mean ± SEM (n = 6–10), *P < 0.05, **P < 0.01, and ***P < 0.001. Data were analysed using one-way analysis of variance (ANOVA) followed by the Tukey-Kramer post hoc test for multiple comparisons
