Ligustrazine (TMP, 25-100 mg/kg; i.p.; once daily for 7 days) can ameliorate liver injury in septic mice: Pathological changes in liver tissues of mice in each group, yellow arrows: hepatic cords; black arrows: hepatocytes. H&E staining results showed that in the Sham group, the liver tissues were structurally intact and morphologically normal, with no cell necrosis; in the CLP group, hepatocytes were swollen and necrotic, and hepatic cords were disorganized, accompanied by extensive inflammatory cell infiltration; compared with the CLP group, liver tissue damage in the CLP + XBJ, CLP + TMP L (25 mg/kg), CLP + TMP M (50 mg/kg), and CLP + TMP H (100 mg/kg) groups was significantly improved, hepatic cord structure was restored, and inflammatory cell infiltration was reduced, with the most significant improvement in the CLP + XBJ and CLP + TMP H groups.
