Effect of melatonin, curcumin, quercetin, and resveratrol on acute ferric nitrilotriacetate (Fe-NTA)-induced renal oxidative damage in rats.
The influence of melatonin, curcumin, quercetin, and resveratrol pretreatment on ferric nitrilotriacetate (Fe-NTA)-induced oxidative renal damage was studied. Male Wistar rats were treated orally once daily for 3 days with melatonin (10 mg/kg), curcumin (50 mg/kg), quercetin (15 mg/kg), and resveratrol (10 mg/kg). One hour after the last dose of antioxidants, a single dose of Fe-NTA was administered (8 mg of Fe/kg body weight, i.p.) to pre-treated animals. Twenty-four hours after Fe-NTA administration, the lipid peroxidation (LP), reduced glutathione (GSH), catalase (CAT), and glutathione peroxidase (GSH-Px) were estimated in kidney homogenates. Iron, zinc, and copper concentrations were estimated in kidney tissue. Administration of Fe-NTA to rats induced renal LP (170%, P < 0.001) and inhibited catalase (78%, P < 0.05) in the kidney. The oral pretreatment with melatonin, curcumin, quercetin, and resveratrol each one was effective in decreasing the Fe-NTA-induced LP (P < 0.001); however, it did not influence the FeNTA-induced inhibition of renal CAT activity. No changes were found in renal GSH level and GSH-Px activity compared to control animals. The pretreatment with antioxidants did not affect the increase in renal iron content, blood urea nitrogen/creatinine ratio, and relative kidney weight of FeNTA-intoxicated rats. The results indicate that the pretreatment with natural antioxidants, curcumin, melatonin, quercetin, and resveratrol, significantly and equally suppressed lipid peroxidation induced by Fe-NTA but had no effect on other markers of FeNTA nephrotoxicity and iron deposition in kidneys.
