Protective action of various doses of compound zinc preparation on cadmium-induced liver damage

Figure 1 Cd toxic group, showing severe hydropic degeneration and sporadic lytic necrosis of the hapatic cells (× 600).

Figure 2 300 μg/mL Zn group, only showing edema of the hepatic cells (× 600).

Figure 3 Cd toxic group; the hepatic cells are nearly dissolved with a lot of vacuoles, flocculent chromatin, swelling endoplasmic reticulum and degenerated mitochondria (× 8000).

Figure 4 300 μg/mL Zn group; the karyotheca of the hepatic cell is clear and regular, the endoplasmic reticulum is nearly normal, but vacuoles are still seen in the cytoplasm (× 16000).
