Photomicrographs of sections in kidney tissues of different groups of rats treated with different nanomaterials: (a) A section in the group treated with group F, showing tubular cystic dilataion (white arrow) and renal tubular casts (black arrow) (H & E X400). (b) A section in the group treated with group G, note glomerular congestion (black arrow) and tubular necrosis and casts (white arrow) (H & E X400). (c) A section in the group treated with group G, show congestion of interstitial blood vessel (black arrow) with few mononuclear inflammatory cells infiltration (white arrow) (H & E X400). (d) A section in the group treated with group H, showing few mononuclear inflammatory cells infiltration (arrow) (H & E X400). (e) A section in the group treated with group H showing mild glomerular congestion (black arrow) and mild tubular epithelial vacuolation (white arrow) (H & E X400). (f) A section in the group treated with group I, note focal area of mononuclear inflammatory cells infiltration (arrow) (H & E X200). g) A section in the group treated with group I showing few mononuclear inflammatory cells infiltration (black arrow) with mild tubular degeneration (white arrow) (H & E X400)
