Histological changes in xenograft tumors (H & E) (×200). Sections from the (A) control, (B) As2O3, (C) Fe3O4, and (D) As2O3/Fe3O4 groups are shown (T, tumor tissue; N, necrosis; M, materials of Fe3O4 or As2O3/Fe3O4. Histological examination revealed that the necrotic areas in B, C, and D were much larger than the intrinsic necrosis of the tumor shown in A.
