ABSTRACT
Atrazine is a widely applied herbicide to improve crop yield and maintain general health. It has been reported to impair thyroid function and architecture in experimental animals. Alterations in thyroid hormones disrupt normal body function and metabolism. Silymarin, a hepatoprotective flavonolignan, was found to improve thyroid function and body metabolism. Additionally, garlic displays several protective effects on body organs. Therefore, this study explored the prophylactic impact of natural compounds comprising silymarin and garlic extract on disrupted thyroid function, hepatic iodothyronine deiodinase type 1, and metabolic parameters in atrazine-intoxicated male rats. We found that daily pre- and co-treatment of atrazine-intoxicated male rats with silymarin (100 mg/kg, p.o) and/or garlic extract (10 mg/kg, p.o) significantly improved thyroid activation and hepatic functionality as evidenced by the re-establishment of T3, T3/T4, and TSH values as well as ALT and AST activities. Interestingly, individual or concurrent supplementation of the atrazine group with silymarin and garlic extract prevented the down-regulation in hepatic iodothyronine deiodinase type 1. These effects were coupled with the repletion of serum and hepatic antioxidants and the amelioration of lipid peroxidation. In addition, current natural products markedly alleviated weight gain, dyslipidemia, hyperglycemia, glucose intolerance, and insulin resistance. Notably, a cocktail of silymarin and garlic extract exerted superior protection against atrazine-triggered deterioration of thyroid, hepatic, and metabolic functioning to individual treatments. Present findings pinpoint the prophylactic and synergistic influence of silymarin and garlic extract combinatorial regimen on thyroid activation and body metabolism via enhancing antioxidant potential, maintaining hepatic function, and iodothyronine deiodinase type 1.
