| Abstract: |
| Objective To optimize the animal model of liver injury that can properly represent the pathological characteristics of dampness-heat jaundice syndrome of traditional Chinese medicine. Methods The liver injury in the model rat was induced by α-naphthylisothiocyanate (ANIT) and carbon tetrachloride (CCl4 ) respectively, and the effects of Yinchenhao Decoction (茵陈蒿汤, YCHD), a proved effective Chinese medical formula for treating the dampness-heat jaundice syndrome in clinic, on the two liver injury models were evaluated by analyzing the serum level of alanine aminotransferase (ALT), asparate aminotransferase (AST), alkaline phosphatase (ALP), malondialchehyche (MDA), total bilirubin (T-BIL), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) as well as the ratio of liver weight to body weight. The experimental data were analyzed by principal component analytical method of pattern recognition. Results The ratio of liver weight to body weight was significantly elevated in the ANIT and CCl4 groups when compared with that in the normal control (P<0.01). The contents of ALT and T-BIL were significantly higher in the ANIT group than in the normal control (P<0.05,P<0.01), and the levels of AST, ALT and ALP were significantly elevated in CCl4 group relative to those in the normal control P<0.01). In the YCHD group, the increase in AST, ALT and ALP levels was significantly reduced (P<0.05, P<0.01), but with no significant increase in serum T-BIL. In the CCl4 intoxicated group, the MDA content was significantly increased and SOD, GSH-PX activities decreased significantly compared with those in the normal control group, respectively (P<0.01). The increase in MDA induced by CCl4 was significantly reduced by YCHD P<0.05). Conclusion YCHD showed significant effects on preventing liver injury progression induced by CCl4, and the closest or most suitable animal model for damp-heat jaundice syndrome may be the one induced by CCl4.
