초록
Obesity is a worldwide problem that contributes to serious diseases, including diabetes, hypertension, and atheroscle- rosis. Recently, much research has examined functional natural materials and their anti-obesity activity. This study investigated the effect of enzyme-treated Ecklonia cava extracts on mice fed a high fat diet. To test the anti-obesity effects of a diet containing the enzyme-treated E. cava extracts (EEc), C57BL/6NTacSam mice were divided into six groups : normal diet (ND), high-fat diet (HFD), high-fat with Garcinia extract diet (GHD), and three high-fat with EEc diet (EHD250, EHD500, and EHD1000) groups. After 9 weeks, body weight was increased significantly in the HFD group compared to all of the EHD groups, and the weights of the liver, perirenal fat and epididymal fat paral- leled the increase in body weight. The serum GOT, GPT, triglyceride, total cholesterol, and LDL-cholesterol levels were lower in the EHD1000 group than in the HFD group. The glucose and leptin concentrations were lowest in the EHD1000 group and C/EBP family expression was decreased in a dose-dependent manner. These results indicate that E. cava extracts not only have anti-oxidation functions but also anti-obesity effects.
Abstract
Obesity is a worldwide problem that contributes to serious diseases, including diabetes, hypertension, and atheroscle- rosis. Recently, much research has examined functional natural materials and their anti-obesity activity. This study investigated the effect of enzyme-treated Ecklonia cava extracts on mice fed a high fat diet. To test the anti-obesity effects of a diet containing the enzyme-treated E. cava extracts (EEc), C57BL/6NTacSam mice were divided into six groups : normal diet (ND), high-fat diet (HFD), high-fat with Garcinia extract diet (GHD), and three high-fat with EEc diet (EHD250, EHD500, and EHD1000) groups. After 9 weeks, body weight was increased significantly in the HFD group compared to all of the EHD groups, and the weights of the liver, perirenal fat and epididymal fat paral- leled the increase in body weight. The serum GOT, GPT, triglyceride, total cholesterol, and LDL-cholesterol levels were lower in the EHD1000 group than in the HFD group. The glucose and leptin concentrations were lowest in the EHD1000 group and C/EBP family expression was decreased in a dose-dependent manner. These results indicate that E. cava extracts not only have anti-oxidation functions but also anti-obesity effects.
