Nanoparticles should be investigated under the laboratory conditions for using in treatment of diseases. This study aimed to investigate the effects of nanoparticles of iron-zinc (Fe2O4Zn) on the factors kidney male rats Wistar. In this experimental study, 24 male Wistar rats were randomly divided into 3 groups containing two experimental and one control group. The control group received 0.5 ml of saline solution but others groups received 0.5 ml of iron nanoparticle with concentration of 100 ppm and 200 ppm, respectively for 7 consecutive days injected intraperitoneally. On the second, seventh and fourteenth day after treatment, blood from the corner of the eyelids was done with capillary tube. Urea, uric acid, and creatinine were measured using ELISA method. Results showed that urea and uric acid levels in the seventh and fourteenth days after treatment at a dose of 100 ppm and 200 ppm were decreased. The creatinine values at 2, 7 and 14 d after treatment 100 ppm and 200 ppm were increased. At a low dose, nanoparticles sediment in the connective tissue and cytoplasm of proximal and distal renal cell and at high doses of nanoparticles, deposit is made in cells of the proximal tubule and in the central part of kidney. Levels of urea and uric acid were reduced and creatinine was increased. The results of histological showed nanoparticle deposition in the kidney. The application of Fe2O4Zn nanoparticles in the biological system had no stable and long-term toxic effects on the animal body.
