Objectives:We investigated the effects of mountain cultivated ginseng water boiled extract(MCG) on blood glucose and insulin levels, and examined whether lipid metabolism are improved by it in male db/db mice(a murine model of type 2 diabetes mellitus). Methods:9 weeks old, male db/db mice were divided into 5 groups: C57BL/6J normal, control, MCG-250㎎/㎏ (MCG-1), MCG-500㎎/㎏(MCG-2) and MCG-1000㎎/㎏(MCG-3). After mice were treated with MCG for 8 weeks, we measured body weight, food intake, fat weight, visceral organ weight and blood glucose, insulin and lipid levels. Results:1. We found no difference in body weight, food intake, fat weight and visceral organ weight among the animal groups. 2. Compared with controls, MCG-treated mice had lower blood glucose level and higher blood insulin levels, the magnitude of which was prominent in MCG-2. 3. Compared with controls, MCG-treated mice had lower LDL-cholesterol and higher HDL-cholesterol levels. 4. Compared with controls, MCG-treated mice had blood triglyceride and free fatty acid levels, the magnitude of which was prominent in MCG-2. 5. Blood AST and ALT concentrations were not changed by MCG, indicating MCG do not show any toxic effects.Conclusions:These results demonstrate that MCG effectively increases blood insulin level and decreases blood glucose level, blood lipid levels, and prevents and improves diabetic dyslipidemia and cardiovascular disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
