Abstract
d-Galactosamine (d-GalN) is a well-known toxin that causes many metabolic and morphological abnormalities resulting in advanced renal failure and liver damage. Occupational exposure to low-level ionizing radiation (<1 Gy) was shown to enhance cell protection via attenuating an established inflammatory process. The present study was therefore aimed to investigate the protective impact of Amphora coffaeiformis extract and low dose gamma radiation against d-GalN induced renal damage in rats. Forty-eight adult male Swiss albino rats were distributed equally into eight groups. The measurements included antioxidants activities (superoxide dismutase, catalase and glutathione peroxidase) as well as lipid peroxidation level in kidney tissue. Also, kidney function tests and inflammatory markers (tumor necrosis factor alpha and nuclear factor kappa-light-chain-enhancer of activated B cells) were measured. Additionally, relative quantification of kidney nuclear factor erythroid 2-related factor 2 (Nrf-2) gene was estimated. Histopathological examination was also performed in kidney tissue. The results revealed decreases in antioxidant activities and downregulation of Nrf-2 expression accompanied by increases in lipid peroxidation level, kidney function tests and inflammatory markers in d-GaIN group. The treatment with Amphora algal extract and low dose gamma radiation ameliorated the previous measurements which were harmony with histopathological findings. In conclusion, A coffaeiformis extract and low dose gamma radiation provided marked functional and histological effects in the treating acute renal damage induced by d-GalN in rats.
