Ox-CS/CeRT NPs inhibited oxidative stress and morphological changes in lung tissue. A Immunohistochemical staining of the macrophage marker F4/80 (brown) in mouse lung tissue. Scale bar = 50 μm. B Quantification of F4/80 positivity. C Protein concentration in BALF. D Total cells in BALF. E Lung wet/dry ratio. F SOD activity and G MDA level in the lung tissue. H H&E-stained pathological sections of lung tissue. Scale bar = 50 μm. n = 5 per group. Data are shown as mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001
