OBJECTIVE: To study the action mechanism of kunzao tiaozhi capsule in the treatment of fatty liver with hyperlipidemia.METHODS: A total of 59 rats were randomly divided into normal control group(n=10),model group(n=11),positive control group(n=10) and kunzao tiaozhi capsule group(at high,medium and low doses,n=9,9,10).Rat model with fatty livers was established in all the groups except the normal control group by feeding high-fat forage and 30% alcohol,and the corresponding solvents or medicine were given during the modeling,10 weeks later,the S-phase cell percentages(SPF) of the liver cells in rats and proliferation index(PI) were determined by flow cytometry methods.RESULTS: As compared with the normal control group,PI and SPF values in the modeled rats increased significantly(P
