Chrysin attenuates sodium arsenite-induced nephrotoxicity in rats by suppressing oxidative stress and inflammation.
BACKGROUND: We aimed to study the beneficial property of chrysin (CHR) by targeting its antioxidant and anti-inflammatory effects on nephrotoxicity induced by sodium arsenite (SA).MATERIALS & METHODS: We have used the 35 male Wistar rats in five equal groups (n = 7). Normal saline in (5 ml/kg; p.o.; 21 days) was given to the control group. Sodium arsenite (10 mg/kg; p.o.; 14 days) was given to the SA group. CHR (25, 50 and 100 mg/kg; p.o.; 21 days) and SA (10 mg/kg; p.o.; 14 days from the 7th day of the experiment) was given to the SA + CHR 25, 50 and 100 groups. On the 22nd day of the experiment, the animals' bloods and kidneys were taken, and then we have performed functional, biochemical and histological assessment.RESULTS: CHR pre- and alongside administration (more potently at dose of 100 mg/kg) with SA reduced the SA-induced alterations in serum creatinine and blood urine nitrogen levels. Increased levels of protein carbonyl, myeloperoxidase, malondialdehyde and nitric oxide in kidney tissue were decreased by CHR treatment. CHR administration increased the levels of glutathione and activities of glutathione peroxidase, catalase and superoxide dismutase in renal tissue. Moreover, treatment with CHR reduced the levels of inflammatory mediators including interleukin 1 beta and tumor necrosis factor alpha in renal tissue. The renal histological lesions induced SA were mitigated by CHR treatment in dose dependent manner.CONCLUSION: The results of present study suggested that administration of CHR before and alongside with SA attenuated the renal toxic effects of SA via antioxidative stress and anti-inflammatory effects.
