Results are mean ± SE (n = 6–7). Different letters (A-C) are significantly different (p < 0.05, one-way ANOVA) according to the Tukey’s test. NC: normal control, DC: diabetic control, PC: 30 mg/kg of pioglitazone, HCO: high-dosage C. obtusa var. formosana leaf extracts, LCO: low-dosage C. obtusa var. formosana leaf extracts.
