Our aim was to study the histological, histochemical and genotoxic effects of ZnO NPs on the kidney of adult male rabbits. Fifteen adult male rabbits were divided equally into three groups. Group I was the control group; group II was the low dose treated group, in which rabbits were intraperitonial injected with ZnO NPs (100 mg/kg/day) for 14 days; and in group III was the high dose treated group, rabbits were injected intra peritonially with ZnO NPs (250 mg/kg/day) for 14 day. At the end of the experiment, specimens from the kidney were taken and stained by H&E, PAS and Masson trichome stains. Also bone marrows were isolated for flow cytometry to study genotoxicy. ZnO NPs was nephrotoxic and led to prominent histopathological changes in the kidney. There were destructions of the renal tubules, in form of loss of brush border, vacuolation of cytoplasm and intratubular protein depositions. Also there was interstitial infiltration of inflammatory cells. The renal corpuscles were dilated and congested. There was increase in apoptotic cell rate of bone marrow samples and showed greater and distinct fragmentation or shearing DNA. ZnO NPs had cytotoxic and genotoxic effects in the kidney. It increased apoptotic rate of the bone marrow cells and fragmentation of DNA. ROS may be the main cause of cytotoxic effects. ZnO NPs was toxic in dose dependent manner. Keywords: apoptosis, cell cycle, DNA fragmentation, Histology, Histochemistry, genotoxicity, Zinc oxide.
