Protective Effect of Tang Wang One Decoction on the Retinal Vessels of Diabetic Rats

Figure 5

Effects of TWOD on ultrastructural changes in diabetic rats. TWOD group and CaD group received a single dose of 60 mg/kg STZ to induce diabetes and control rats received vehicle. TWOD group was treated with 10 g/kg TWOD. CaD group was treated with 250 mg/kg CaD. Control group and model group were treated with the same volume of vehicle. The retinas were prepared for electronic microscopic observation. Typical retinal ultrastructure was shown in this figure: control group (a), model group (b), TWOD group (c), and CaD group (d). Two black arrows correspond to basement membrane. Red arrows correspond to vacuoles. Triangles correspond to microvilli-shaped protuberance. ○E: endothelial cells; ○V: vessels.
