Figure 7
Light microscopic analysis of 6 major tissues the incubated by CNTs. The tissue samples were fixed and preserved in 4% buffered formaldehyde for at least 24 h. Paraffin blocks were then sectioned by 3–5 μm thickness for hematoxylin and eosin staining. Slides were studied by OLYMPUS-BX51 microscope. A relative shrinkage was observed in some of the liver cells (×10).
