(a–e) The expression of NF-κB (×400) in the retina of control, NGT, IGT, DM, and DKD stage, respectively, using IHC; (f–j) the expression of VEGF (×400) in the retina of control, NGT, IGT, DM, and DKD stage, respectively, using IHC; (k–o) the expression of ICAM-1 (×400) in the retina of control, NGT, IGT, DM, and DKD stage, respectively, using IHC; (p–r) the quantification of NF-κB, VEGF, and ICAM-1. a vs. the control group. b vs. NGT. c vs. IGT. d vs. DM.
