Abstract
|
|
|
The effects of dietary supplementation with aqueous Hovenia dulcis Thunb. extract (HDE) (20 weeks) on high-fat diet (HFD)-induced nonalcoholic fatty liver disease and dyslipidemia were evaluated in mice. Supplementation with 200 and 800?mg/kg feed HDE (HDE200 and HDE800, respectively) resulted in no significant difference in growth in the HFD-fed groups. The triglyceride (TG) levels and free fatty acids were significantly decreased, whereas high-density lipoprotein cholesterol was increased in the HDE800 group (P?.05). The hepatic intracellular TGs were significantly decreased in the HDE-fed groups and lipogenic enzymes (acetyl CoA carboxylase, fatty acid synthase, stearoyl CoA desaturase, and diacylglycerol transferase) in the liver were significantly downregulated by HDE supplementation (P?.05). The diminished serum antioxidant enzyme activities in the HFD group were effectively restored by HDE supplementation, which also contributed to the attenuation of hyperlipidemia.
