Objectives : The aim of this study is to investigate Daesiho-tang(Dachaihu-tang) water extracts (DSTE) have potent anti-obesity activities in a high-fat diet-induced obesity mouse model. Methods : In this study, we designed three groups (normal diet group, high-fat diet group, high-fat diet plus DSTE group for 7-weeks oral administration). Results : Increases in body weight were inhibited by 7-weeks oral administration of DSTE at a 500 mg/kg concentration in this animal model. Results from blood lipid analysis showed that the levels of triglyceride, total cholesterol and LDL-cholesterol were significantly lowered by DSTE administration, also HDL-cholesterol was increased more than high-fat diet-induced obese mouse. To understand the underlying mechanism at the molecular level, the effects of DSTE were examined on the expression of the genes involved in lipogenesis by real-time PCR. In epididymal fat and liver of DSTE-treated mice, the mRNA level of lipogenic genes such as sterol regulatory element binding protein 1 and fatty acid synthase were decreased, which was well correlated with the reduction of the tissues weight. Conclusions : These results suggest that DSTE may have great potential as a novel anti-obesity agent.

Objectives: The aim of this study is to evaluate the effects of Bangpungtongseong-san (Fangfengtongsheng-san, BTS) and Daesiho-tang (Dachaihu-tang, DST) on weight loss and improvement in lipid metabolism and glucose metabolism. Furthermore, we intend to develop a prediction model for drug effects through the analysis of the single nucleotide polymorphism (SNP), gut-microbiota, and the expression of immune-related biomarkers. Methods: This study is a single-center, randomized, double-blind, parallel-design clinical trial. One hundred twenty-eight participants will be assigned to the BTS group (n=64) and DST group (n=64). Both groups will be administered 4 g medication three times a day for up to 2 weeks. The primary outcomes is weight loss. The secondary outcomes include bioelectrical impedance analysis, waist circumstance, body mass index, total cholesterol, high-density lipoprotein, triglyceride, insulin resistance. The exploratory outcomes include 3-day dietary recall, food frequency questionnaire, quality of life questionnaire, gut microbiota analysis, immune biomarkers analysis, and SNP analysis. Assessment will be made at baseline and at week 4, 8, and 12. Conclusions: This protocol will be implemented by approval of the Institutional Review Board of Dongguk University. The results of this trial will provide a systematic evidence for the treatment of obesity and enable more precise herbal medicine prescriptions.
