Abstract
Deltamethrin is a broad-spectrum synthetic pyrethroid insecticide and acaricide widely used for agricultural and veterinary
purposes. However, its human and animal exposure leads to hepatonephrotoxicity. Therefore, the present study was
undertaken to examine the hepatonephroprotective and antioxidant potential of Spirulina platensis against deltamethrin
toxicity in male Wistar albino rats. Deltamethrin treated animals revealed a significant increase in serum biochemical
parameters as well as hepatic and renal lipid peroxidation but caused an inhibition in antioxidant biomarkers. Spirulina
normalized the elevated serum levels of AST, ALT, APL, uric acid, urea and creatinine. Furthermore, it reduced deltamethrininduced
lipid peroxidation and oxidative stress in a dose dependent manner. Therefore, it could be concluded that spirulina
administration able to minimize the toxic effects of deltamethrin by its free radical-scavenging and potent antioxidant
activity.
