Abstract: In order to explore whether resveratrol (RSV) had a protective effect on the liver injury of mice induced by zearalenone (ZEA), 40 clean grade male BALB/c mice were randomly divided into 5 groups:Control group (normal saline), ZEA group (40 mg/kg), different concentrations of RSV (50, 100 or 200 mg/kg) and ZEA (40 mg kg) co-treatment groups, with 8 mice in each group. Each group was administered by gavage for 12 days. After the experiment, the liver samples of mice were collected, the liver coefficient was calculated, the liver pathological changes were observed by HE staining and immunohistochemical staining, and the liver NF-κB was detected. The content of malondialdehyde (MDA), the activities of superoxide dismutase (SOD) and catalase (CAT) in liver tissue were detected by colorimetry. The activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in serum were detected by colorimetry. The levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and IL-1β in serum were detected by ELISA method. The results showed that compared with control group, the liver tissue of ZEA group had obvious pathological changes. Compared with ZEA group, the liver histopathological changes of mice treated with different concentrations of RSV and ZEA were reduced. Immunohistochemical results showed that compared with control group, liver NF-κB protein expression was increased. Compared with ZEA group, liver NF-κB protein expression of different concentrations of RSV and ZEA co-treatment groups were decreased. Compared with control group, the liver coefficient and the content of MDA in liver tissue in ZEA group were extremely significantly increased (P<0.01), the activities of SOD and CAT in liver tissue were significantly or extremely significantly decreased (P<0.05; P<0.01), the activities of AST, ALT and LDH, and the contents of IL-6 and TNF-α and IL-1β in serum were extremely significantly increased (P<0.01). Compared with ZEA group, CAT activity in liver tissue of different concentrations of RSV and ZEA co-treatment groups were significantly or extremely significantly increased (P<0.05; P<0.01); Activities of AST, ALT and LDH and the contents of IL-6 and IL-1β in serum were significantly or extremely significantly decreased (P<0.05; P<0.01); SOD activity in liver tissue and the content of TNF-α in serum of 50 mg/kg RSV and ZEA co-treatment group were significantly increased (P<0.05) and extremely significantly decreased (P<0.01), respectively; The liver coefficient and MDA content in liver tissue were significantly or extremely significantly decreased in 100 and 200 mg/kg RSV and ZEA co-treatment groups (P<0.05; P<0.01). The results showed that ZEA had serious oxidative and inflammatory effects on the liver, and RSV had a certain protective effect on the liver injury caused by ZEA poisoning, 100 mg/kg RSV had the best protect effect.
