The effect of the nano-oxygen-carrier on the histology of tumor. a H&E staining of the tumor section. Twenty four hours after IV injection of saline or lip(PFH), the tumor was irradiated with X-ray (10 Gy). One day after irradiation, tumors were dissected for H&E staining. The white bar indicates 200 μm. b TUNEL staining of the tumor section. Twenty four hours after IV injection of saline or lip(PFH), the tumor was irradiated with X-ray (10 Gy). One day after irradiation, tumors were dissected for TUNEL staining. Brown signal indicates apoptotic cells. c Quantitation of apoptotic cells in saline and lip(PFH) groups. *P < 0.05 compared with saline group
