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

Figure 6

Effects of TWOD on MMP-9 levels 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 with trypsin digestion and stained with immunohistochemistry stain. The expression of MMP-9 was shown in this figure: control group (a), model group (b), TWOD group (c), and CaD group (d). Results were analyzed by one-way ANOVA, followed by a LSD post hoc test for multiple comparisons. Values are demonstrated as mean ± SD; ; versus control group; versus model group (e).
