Abstract

Background:   The present study comprised two distinct experiments. The first experiment involved a field survey conducted in the Diyala Bridge area of Baghdad, Iraq, spanning from December 2021 to May 2022. Soil, milk, and blood samples were collected from locally grazed cattle to ascertain uranium concentrations. In the second experiment, rats were subjected to poisoning with Uranyl acetate. Upon completion of the experiment, samples of liver, kidneys, and blood were collected for histopathological and biochemical analyses. Methods : Twenty-four albino male rats were divided equally and randomly into two groups i.e., control group and intoxicated group. Uranyl acetate was given daily for 120 days by 0.05 mg/kg to the latter group. At the end of the experiment liver and kidney sample were taken for histopathological examination and stained by Masson-trichrome stain. Results : The finding of eosin and hematoxylin stain and biochemical assay for CuZn-SOD U/mg and catalase K/mg protein were showed significantly elevated while liver tissue showed necrosis atrophy atherosclerosis cirrhosis and carcinoma characterized by irregular cell mitotic figure extensive fibrous tissue, tissue kidney presented interstitial hemorrhage and multiple granuloma. Conclusion : Intoxicant by Uranyl acetate showed significant elevating for CuZn-SOD U/mg and catalase K/mg protein, in contrast liver tissue showed necrosis atrophy atherosclerosis cirrhosis and carcinoma, tissue kidney presented interstitial hemorrhage and multiple granulomas.
