Abstract: 

The objective of this study was to investigate the propensity of permethrin (PTN) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin C. Forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 mgL-1 permethrin and 0 mgL-1 vitamin C), PTN-0.16 (0.16 mgL-1 permethrin), PTN-0.32 (0.32 mgL-1 permethrin), PTN-0.64 (0.64 mgL-1 permethrin), Vit. C (17.2 mgL-1 vitamin C), and PTN-0.64+Vit. C (0.64 mgL-1 permethrin and 17.2 mgL-1 vitamin C). Results obtained showed that permethrin significantly (P<0.05) increased ALT, AST and LDH activities in the liver perfusion medium and malondialdehyde (MDA) level in liver tissue. The values of reduced glutathione (GSH) and total antioxidant capacity (FRAP) in the liver tissue were significantly decreased due to permethrin administration. Pearson’s correlation analysis revealed a positive correlation between MDA concentration and ALT, AST and LDH activities in the permethrin groups, suggesting that the enhanced lipid peroxidation may be linked to hepatic damage caused by permethrin. On the other hand, treatment with vitamin C in the PTN-0.64+Vit. C group increased the values of GSH and FRAP, and decreased the level of MDA and the activities of hepatic enzymes, when compared to the PTN-0.64 group. The present study revealed that vitamin C could ameliorate permethrin-induced oxidative damage by decreasing lipid peroxidation and altering antioxidant defense system in liver of rainbow trout.
