Imidacloprid enhances liver damage in Wistar rats: Biochemical, oxidative damage and histological assessment

Journal Title: Journal of Coastal Life Medicine - Year 2017, Vol 5, Issue 12

Abstract

Objective: To investigate the potential adverse effects of imidacloprid on biochemical parameters, oxidative stress and liver damage induced in the rat by oral sub-chronic imidaclopride exposure. Methods: Rats received three different doses of imidacloprid (1/45, 1/22 and 1/10 of LD50) given through gavage for 60 days. Two dozen of male Wistar rats were randomly divided into four experimental groups. Liver damage was determined by measuring aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and lactate dehydrogenase leakages. The prooxidant-antioxydant status in hepatic tissue homogenate was evaluated by measuring the degree of lipid peroxidation, the antioxidant enzymes activities such as catalase, superoxide dismutase and glutathione peroxidase (GPx). Results: The relative liver weight was significantly higher than that of control and other treated groups at the highest dose 1/10 of LD50 of imidacloprid. Additionally, treatment of rats with imidacloprid significantly increased liver lipid peroxidation (P ≤ 0.05 or 0.01) which went together with a significant decrease in the levels of superoxide dismutase and catalase activities. Parallel to these changes, imidacloprid treatment enhanced liver damage as evidence by sharp increase in the liver enzyme activities of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and lactate dehydrogenase. These results were also confirmed by histopathology. Conclusions: In light of the available data, it is our thought that after imidacloprid sub-chronic exposure, depletion of antioxidant enzymes is accompanied by induction of potential oxidative stress in the hepatic tissues that might affect the function of the liver which caused biochemical and histopathological alteration.
