摘要
1.It has been demonstrated that the ingestion of foods containing quercetin protects against the toxicity of single pesticides. The aim of this study is to make a comprehensive elaboration about the protective effect of quercetin against multi-organophosphorous pesticides induced nephrotoxicity by measuring indices in rat kidney, urine and serum. Rats were divided into six groups (n=10/group): control, two different doses of quercetin, pesticide mixture (PM), and different doses of quercetin plus PM-treated groups.2.The following parameters were significantly changed in PM-treated groups compared with the control (p<0.01). In kidney, malondialdehyde level raised; catalase, superoxide dismutase activities and glutathione levels were decreased. Comet assay of nephrocytes showed that the proportion of DNA in the tail and tail length increased. In urine, 2-microglobulin, retinol-conjugated protein levels and N-acetyl--d-glucosaminidase activity showed increasing response; meanwhile uric acid level was decreased. In serum, creatinine and urea nitrogen levels were increased. However, the anomaly changes of indexes mentioned above in PM-treated group were alleviated when simultaneously administrated with 50mg/kg body weight/day quercetin (p<0.05).3.From the present findings, it can be evaluated that quercetin may protect against adverse effects resulted from multi-organophosphorous pesticides with significant high levels of uptake in man provided.
