초록

Objectives We aimed to find out the improvement effect of Baekhogainsam-tang (Baihu Jia Renshen-tang, BIT) on metabolic syndrome and alteration of microbiota and gene expression.
Methods We used male C57BI/6 mice and randomly assigned them into three groups.
Normal control group was fed 10% kcal% fat diet, high-fat diet (HFD) group was fed 45% kcal% fat diet and 10% fructose water. BIT group was fed same diet as HFD group and treated by BIT for once daily, 6 days per week, total 8 weeks. We measured their body weight and food intake every week and performed oral glucose tolerance test 1 week before the end of the study. Then we collected the blood sample to measure triglyceride, total cholesterol, high-density lipoprotein cholesterol, insulin, and hemoglobin A1c. We harvested tissue of liver, muscle, fat, and large intestine for quantitative polymerase chain reaction (qPCR) and histopathological examination. Fresh fecal samples were collected from each animal to verify alterations of gut microbiota and we used RNA from liver tissue for microarray analysis.
Results The body weight and fat weight of BIT group were reduced compared to HFD group. The qPCR markers usually up-regulated in metabolic syndrome were decreased in BIT group. Bacteroides were higher in BIT group than other groups. There were also differences in gene expressions between two groups such as Cyp3a11 and Scd1.
Conclusions We could find out BIT can ameliorate metabolic syndrome and suggest its effect is related to gut microbiota composition and gene expression pattern.
