Figure 1

Mice lung tissues were obtained on day 3, 7, 14 after administration by PM2.5. Samples were stained using H&E. Histopathological lesions and changes were assessed by histological analyses of six random fields per sample by optical microscope. PM2.5 significantly increased cells infiltration and altered alveolar walls structure (A). PM2.5 facilitated the accumulation of inflammatory cells in BALF. Total cells (B), neutrophils (C), lymphocytes (D) and macrophages (E) in BALF were counted using Giemsa staining. Results are represented as means ± SEM (**P < 0.01, *P < 0.05 versus the control group).
