Protective effect of cyanidin-3-O-β-D-glucopyranoside fraction from mulberry fruit pigment against oxidative damage in streptozotocin-induced diabetic rat bladder.

Aims: To determine whether cyanidin-3-O-β-D-glucopyranoside (C3G) fraction from mulberry fruit pigment has protective effects against bladder dysfunction on streptozotocin-induced diabetic rats

Methods: Sprague-Dawley rats were divided into three groups (n = 12 in each): normal, diabetes (DM), and DM treated with C3G fraction (DM + C3G). The DM and DM + C3G groups received a single injection of streptozotocin (50 mg/kg) intraperitoneally. Four weeks after the induction of diabetes, the DM + C3G group was treated with daily oral C3G (10 mg/kg) dissolved in water, for 8 weeks.
