Abstract
Background
This study aimed to assess hepatotoxicity and nephrotoxicity of Lambda-cyhalothrin (LCT ) and the protective effect of rutin alone and in combination with β-cyclodextrin ( β –CD).
Materials and Methods
Male Wistar rats were divided into five groups: group 1: was used as a control and received a standard diet and water. group 2, 3, 4 and 5 were orally administered with LCT (7.6 mg/kg body weight), rutin (200 mg/kg body weight) LCT and rutin (at the same doses as in group 2 and group 3), and LCT and a mixture of rutin with β-CD (400 mg/kg body weight), respectively. All experimental animals were orally gavaged 5 days/week for 60 days.
Results
Our data revealed that LCT-induced liver and kidney injuries were related to the up-regulated expression of TNF- α and down-regulated expression of NRF-2 genes mRNA, whereas these effects were reversed with rutin treatment. LCT-induced oxidative stress altered the histological picture, and the hematological and biochemical parameters.
Conclusions
Treatment with a rutin-β-CD complex had preventive potential against LCT via suppression of oxidative stress and augmentation of the antioxidant defense system.
