Decrease of Plasma Glucose by Hibiscus taiwanensis in Type-1-Like Diabetic Rats
Figure 3
Effect of Hibiscus taiwanensis on insulin sensitivity in STZ-diabetic rats. Hibiscus taiwanensis at 500 mg/kg was treated orally into STZ-diabetic rats three times daily for three days. Then, the animals were injected intravenously with exogenous insulin at the indicated dose to show the changes in plasma glucose as open circles. Changes of plasma glucose in another group of STZ-diabetic rats receiving a similar treatment with vehicle at the same volume are shown as closed circles. Values (means ± SE) were obtained from each group of eight animals. * as compared with values from vehicle-treated group (closed circles) at the same dose of insulin.
