Photomicrographs of kidney sections stained with hematoxylin and eosin (scale bars = 50 μm), showing: (A) control group, normal architecture of renal corpuscles with their glomeruli (arrow) and renal tubules (asterisk); (B) intoxicated group with 600 mg/kg body weight/day n-ZnO particles for 5 days, shrinkage and fragmentation of many glomeruli (arrows) with many renal tubules showing degeneration, necrosis (arrowhead) and exfoliation of their lining epithelium (curved arrow); (C) Qur-treated group, shrinkage and fragmentation in many glomeruli (arrow) with necrosis (arrowhead) and exfoliation of lining epithelial cells of many renal tubules (curved arrow); (D) Arg-treated group, normal architecture of renal corpuscles with their glomeruli (arrow) as well as normal renal tubules (asterisk); and (E) Qur + Arg-treated group, few glomeruli with shrinkage and fragmentation, and few renal tubules with epithelial cell exfoliation (curved arrows).
