Values (mean ± SE) were obtained from each group of six rats. The vehicle used to dissolve the testing drugs was given at the same volume. a 𝑃 < . 0 5 —for values obtained from STZ-DN group compared to the values obtained from vehicle-treated normal rats. b 𝑃 < . 0 5 —for values after treatment compared to the values of before vehicle, insulin or phloridzin treatment, respectively.
