Electron examination of liver slices for experimental groups: (A) Hepatic section from the first group (control), (B) Hepatic section from the second group (PPE), (C,D) Hepatic section from the third group (Fe₂O₃-NPs), and (E,F) Hepatic section from the fourth group (PPE plus Fe₂O₃-NPs). The ultrastructures show the hepatic cells (Hc), the nucleus (N) of hepatocytes, the Kupffer cell (K), the mitochondria (M), the Golgi apparatus (Go), the rough endoplasmic reticulum (rER), the lysosome (Ly), the vacuolar hepatic degeneration (VD), and the iron precipitate (arrows) in the slices (15,000×).
