Figure 6

Photomicrographs of kidney sections stained with hematoxylin and eosin (scale bars = 50 μm), showing: (A) control group, normal renal corpuscles with normal glomeruli (arrow) and renal tubules (asterisks); (B) intoxicated group with 1 g/kg body weight/day for 5 days with n-ZnO particles, shrinkage and fragmentation of many glomeruli (arrows). In addition many renal tubules show degeneration, necrosis (arrowheads) and exfoliation of their lining epithelium (curved arrow). (C) Qur-treated group, many glomeruli reveal shrinkage and fragmentation (arrows) with degeneration, necrosis (arrowheads) and exfoliation of epithelial lining cells of the renal tubules (curved arrow). (D) Arg-treated group: Almost all the renal corpuscles with their glomeruli (arrows) as well as the renal tubules (asterisks) are similar to normal architecture. (E) Qur + Arg-treated group, there were few renal tubules with degeneration, necrosis (arrowhead) and exfoliation of their lining epithelial cells (curved arrow).
