Abstract:
To investigate the effect of Jiawei Foshou San and its various combined administration on hepatic P450 enzyme activity and hepatocyte morphology in rats. Rats were orally administered with drugs for four weeks and then sacrificed to prepare liver microsomes. The liver microsomes were incubated with the cocktail method; The metabolites were determined with the rapid liquid chromatography with tandem mass spectrometry (LC-MS/MS) to investigate the hepatocyte P450 enzyme activity. In addition, the hepatic pathological changes were observed by using the hematoxylin and eosin (HE) staining. Compared with the control group, the enzyme activity of CYP1A2 and CYP3A4 in the Jiawei Foshou san group showed a significant rise (P < 0.05); the enzyme activity of CYP1A2, CYP2C9, CYP2D6, CYP2E1 and CYP3A4 in the ferulic acid + ligustrazine group and the ligustrazine + tetrahydropalmatine group showed a significant rise (P < 0.05) ; the enzyme activity of CYP1A2, CYP2D6 and CYP2E1 in the ligustrazine group showed a significant rise (P < 0.05); the enzyme activity of CYP3A4 in the ferulic acid group showed a significant reduction (P < 0.05). After the administration with various drugs, the hepatocyte morphologies in the ferulic acid group and the ligustrazine group were normal. The pathological changes were observed in the tetrahydropalmatine group, such as unclear boundary of hepatic lobules, disordered hepatic cell arrangement, blurred edge, anisokaryosis and infiltration of inflammatory cells. The ferulic acid + tetrahydropalmatine group, the ligustrazine + tetrahydropalmatine group and the Jiawei Foshou San group also showed inflammatory infiltration, but with less pathological changes, particularly the Jiawei Foshou San group. The study result shows that Jiawei Foshou San can induce the enzyme activity of CYP1A2 and CYP3A4, and ligustrazine may be the effective substance for inducing CYP1A2. Its combination with ferulic acid and ligustrazine can significantly reduce the liver toxicity of tetrahydropalmatine.
