Effect of Umbelliferone β-D-galactopyranoside (UFG) photomicrographs of histological change on heart in different groups of rats: (A) Normal control: Normal control group rat showing normal histopathology. (B) Diabetic control: Increased interstitial space and distort the intercalated disc (yellow arrow) in diabetic control group rat histopathology. (C) UFG I (10 mg/kg): Dose UFG (10 mg/kg) treated group rat showing less interstitial space and intercalated disc (yellow arrow) (D) UFG II (20 mg/kg): Dose UFG (20 mg/kg) treated group rat showing only space in intercalated disc (yellow arrow). (E) UFG III (40 mg/kg): Dose UFG (40 mg/kg) treated group rat did not showing any changes in histopathology of heart. (F) Glibenclamide (10 mg/kg): Glibenclamide (5 mg/kg) treated drug shown the normal histopathology of heart. The samples were obtained from the same liver anatomical regions. For each group, 6 rats were examined and 80 pictures were taken. The above picture for each group was chosen randomly from the 80 pictures in this group. Original magnification, 10 × .
