Figure 4

Electron microscope images of rat kidney sections. Rats were dosed with cinnabar (1 g/kg/day) for 8 weeks or 12 weeks. (a), the control group, 8 weeks; (b), the cinnabar group, 8 weeks; (c), the control group, 12 weeks; (d) the cinnabar group, 12 weeks. (a) and (c) show a normal cell nucleus. (b) and (d) show an apoptotic cell nucleus. Scale bar = 1 μm.
