Abstract :

Soshiho-tang (SST; sho-saiko-to in Japanese; xiaochaihu-tang in Chinese) has generally been used to improve liver fibrosiss- and cirrhosis-related symptoms in traditional Korean medicine. Although many studies have investigated the pharmacological properties of SST, its antiobesity effect has not been elucidated. Thus, our present study was carried out to evaluate the antiobesity effect of SST using a high fat diet- (HFD) induced obese mouse model and 3T3-L1 adipose cells. C57BL/6J mice were randomly divided into four groups (n = 6/group), normal diet (ND), HFD-fed group, and HFD- and SST-fed groups (S200: 200 mg/kg of SST; S600: 600 mg/kg of SST) and given HFD with or without SST extract for 8 weeks. 3T3-L1 preadipocytes were differentiated into adipocytes for 8 days with or without SST. In the HFD-fed obese mice, body weight and fat accumulation in adipose tissue were significantly reduced by SST administration. Compared with control -differentiated adipocytes, SST significantly inhibited lipid accumulation by decreasing the triglyceride (TG) content and leptin concentration in 3T3-L1 adipocytes. SST also decreased the expression of adipogenesis-related genes including lipoprotein lipase (LPL), fatty acid binding protein 4 (FABP4), CCAAT/enhancer-binding protein-alpha (C/EBP-[alpha]), and peroxisome proliferator-activated receptor-gamma (PPAR-[gamma]). Our findings suggest that SST has potential as a nontoxic antiobesity medication.
