Fig. 1. Effects of C-DM3 extract on impaired glucose tolerance in diabetic mice. (A) Levels of fasting glucose were measured in the sera of mice. (B) AUC index was calculated using the equation described in the Materials and Methods section. The data are expressed as the mean±SD. C-DM3: C-DM3 extract 500 mg/kg group, AUC: area under the curve, Nor: normal group, HFD: high-fat diet-induced diabetes control group, Met: metformin 500 mg/kg group, SD: standard deviation. *P<0.05 (n=5 per a group), †P<0.01, and ‡P<0.001 vs. normal (a) or control group (b).
