CuONPs instillation caused acute lung injury dose-dependently in mice. A Representative H&E staining images of lung tissues of mice 3 day after intratracheally administration of vehicle, 30, 50 or 100 μg CuONPs, respectively. Scale bar, 200 μm in the upper panels and 50 μm in the bottom panels. B The lung injury scores of H&E staining were calculated. C The cell counts in BALFs collected from indicated groups were determined by automated cell counter. D The protein concentrations of BALF collected from indicated groups were determined by BCA analysis. E The LDH activities of BALFs collected from indicated groups were determined. *indicates p < 0.05 compared with vehicle group
