Histopathological changes of heavy metals Nickel Chloride (II) and Potassium dichromate (VI) on the Liver and Kidney of Swiss Male Mice

Abstract

Heavy metals are a very harmful environmental pollutant, Nickel and chrome induced toxicity and carcinogenicity, with an emphasis on the generation and role of reactive oxygen species is reviewed. Nickel and chrome are a known as haematotoxic, immunotoxic, neurotoxic, genotoxic, reproductive toxic, pulmonary toxic, nephrotoxic, hepatotoxic and carcinogenic agent. The present study revealed the toxic effects of nickel (Ni) (II) and chrome (Cr) (VI) on the liver and kidney structure of mature male mice weighing 20-30 g, (10-13 weeks old), were treated orally with different doses (20, 40 and 60 mg/kg of NiCl2 and 20, 60 and 100 mg/kg of K2Cr2O7). Dramatic Histopathological changes found in the liver and kidney of treated animals included degeneration, nuclear pycnosis, cellular swelling,necrosis, congestion of blood vessels and many others defects .
