Apoptosis of NSCLC cells and pathological sections of the lung tissues of rats treated with saline (A), oridonin powders (B), gemcitabine (C), and oridonin-loaded LPMPs (D) after pulmonary delivery. Apoptosis is indicated by tunel staining (400×). The nuclei are shown by DAPI staining (400×). The merged images of tunel and DAPI staining show the apoptosis in the NSCLC cells. Hematoxylin and eosin (H&E) staining (100×) shows the states of NSCLC cells.
