Background Diazinon (DZN) causes serious liver damage in both humans and animals. In the present study, the hepatoprotective effects of Cynara scolymus L. leaf extract against DZN-induced liver injury were examined. Methods Forty male rats were divided into five groups. The control group received a normal diet. The DZN group received DZN only (25 mg/kg, po). The DZN + Syl group received DZN (25 mg/kg, po) and silymarin (Syl) (50 mg/kg, po). The DZN + Art group received DZN (25 mg/kg, po) and artichoke (Art) leaf extract (1500 mg/kg, po). The Art group received Art leaf extract only (1500 mg/kg, po). After 15 days, serum tumor necrosis factorα (TNF-α), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lipid profile, protein carbonyl content, serum and hepatic malondialdehyde (MDA), hepatic TNF-α gene expression, hepatic catalase (CAT), superoxide dismutase (SOD), and vitamin C (Vit C) weremeasured and histopathological examination was performed. Results DZN caused a significant elevation in serum ALP, AST, ALT, MDA, TNF-α, protein carbonyl, hepatic MDA, and TNF-α gene expression in the DZN group as opposed to the control group. Also, DZN led to the reduction of hepatic CAT, SOD, and Vit C in the DZN group relative to the control group. The administration of Art extract resulted in not only a significant reduction in serum ALP, AST, ALT, MDA, TNF-α, and protein carbonyl but also an improvement of liver histopathological changes and hepatic CAT and SOD activities as opposed tothe DZN group. Conclusions This study confirmed that Art leaf extract has liver protective effects and causes downregulation of oxidative stress in acute DZN-induced liver injury in rats.
