BACKGROUND AND OBJECTIVES: Extensive use of Lambda-cyhalothrin (LTC), a synthetic pyrethroid insecticide, has been associated with serious health problems to the non-target organisms including mammals. The present study investigated the protective effect of naringenin (NGN), an antioxidant flavonoid, against the toxicity induced LTC in the liver of male rats.
MATERIALS AND METHODS: Five groups of rats were assigned as follows; control group, LTC group (6.12 mg kg-1, 1/10 LD50), LTC-NGN group (6.12 mg kg-1 LTC and 50 mg kg-1 NGN), NGN-LTC group (50 mg kg-1 NGN and 6.12 mg kg-1 LTC) and NGN group (50 mg kg-1). Doses were administrated orally for 21 consecutive days.
RESULTS: Administration of LTC induced liver damage as indicated by the increase in the activities of aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase and in the level of total bilirubin in serum. LTC also induced a significant elevation in the levels of serum total lipids, total cholesterol, triglycerides and low-density lipoproteins while high-density lipoproteins decreased. Furthermore, LTC significantly disturbed the oxidant/antioxidant balance in the liver as shown by the elevation in lipid peroxidation, lipid hydroperoxides, protein carbonyl content and conjugated dienes with a concomitant inhibition in the major antioxidants such as reduced glutathione and the activities of superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase. Both post-treatment and pre-treatment with NGN significantly modulated the LTC-induced hepatotoxicity and oxidative stress in rat's liver and pretreatment was found to be more effective in improving most of the studied parameters in both serum and liver tissue.
CONCLUSION: NGN could be used as a safe dietary supplement to protect against the toxicity and oxidative stress associated with the use of LTC.
