Abstract: Objective The aim of this study was to explore the protective mechanism of Danzhi Xiaoyao powder on hepatic damage in rats with D-galactosamine (D-GaIN)/lipopolysaccharide (LPS)-induced acute liver injury (ALI). Methods 110 SD male rats were randomly divided into control, model, low-dose, moderate dose and large-dose of herbal medicine-intervened groups, with 22 rats in each. The ALI model was built-up by D-GaIN/LPS injection intraperitoneally, and the herbal medicine was given by lavage. Serum MDA, SOD, GSH-PX, IL-6, IL-1β, TNF-α levels were detected by ELISA, and serum HA, LN and Ⅲ-PC levels were assayed by RIA. Results Serum AST, ALT, bilirubin and MDA levels in model group were (12081.3±587.7)U/L, (7658.7±742.2)U/L, (104.3±10.3)μmol/L and (8.9±1.1)mmol/mL, all significantly higher than [(171.9±17.2)U/L, (60.5±6.2)U/L, (2.4±0.2)μmol/L and (2.5±0.3)mmol/mL, respectively, P<0.05] in the control; serum SOD and GSH-PX levels were (14.3±1.7)U/mL and (7.1±0.7)μmol/L, both significantly lower than [(38.6±4.4)U/mL and (21.9±2.2)μmol/L, P<0.05] in the control, while serum SOD and GSH-PX levels in three herbal medicine-intervened groups significantly higher than those in the model (P<0.05); serum IL-6, IL-1β and TNF-α levels in the model were (194.3±20.5)ng/mL, (24.7±2.5)ng/ml and (864.5±87.3)ng/mL, significantly higher than [(90.1±10.3)ng/mL, (5.2±1.0)ng/mL and (30.2±4.1)ng/mL in the control, while all significantly decreased compared to those in the model in three herbal medicine-intervened groups (P<0.05); serum HA, LN and Ⅲ-PC levels were (286.3±29.1)ng/ml, (297.4±30.5)ng/ml and (257.1±26.7)ng/ml, all significantly higher than [(55.1±6.2)ng/mL, (75.1±7.6)ng/mL and (61.9±6.2)ng/mL] in the control, while all significantly decreased compared to those in the model in three-herbal medicine-intervened groups(P<0.05). Conclusion Danzhi Xiaoyao powder could exert significant protective effect on liver functions in rats with D-GaIN/LPS-induced ALI, and the mechanism by which it works might be related to obvious inhibition of oxidative stress and inflammation response.
