Intravitreal Bevacizumab Injection Attenuates Diabetic Retinopathy in Adult Rats with Experimentally Induced Diabetes in the Early Stage

Figure 5

Western blot analysis of VEGF (a), iNOS (b), eNOS (c), and nNOS (d) protein expression levels in the retina in the NC, DM3w, DM6w, and DM9w groups, including the immunoreactive bands of VEGF (21 kDa), iNOS (130 kDa), eNOS (140 kDa), nNOS (155 kDa), and β-actin (42 kDa). Bar graphs representing optical density (mean ± SD). The expression levels were all increased after diabetes induction. (e) NO concentration in the NC, DM3w, DM6w, and DM9w groups. NO concentration was significantly increased in the retina at 3w, 6w, and 9w after diabetes induction when compared with that of control rats. and .
