The effects of PM014 on histopathological changes in lung tissues Control, phosphate buffered saline (PBS)-treated; PM, pm10 + PBS; 50, pm10 + 50 mg/kg PM014; 100, pm10 + 100 mg/kg PM014; 200, pm10 + 200 mg/kg PM014; and DEXA, pm10 + 10 mg/kg dexamethasone. a The experimental schedule was represented. b Lung tissues were stained with H&E to observe inflammatory cell infiltration. Infiltrated immune cells were marked with arrows. Magnification, 20x. c Quantification of inflammatory foci. Data are expressed as mean ± standard error (***P < 0.001 versus control; ###P < 0.001, versus PM + PBS; n = 7–10)
