Immunohistochemical Analysis of GFAP protein (a), VEGF (c), and PEDF (e) in the retinas of the rats. Densitometric quantifications of immunoreactivity are in (b), (d), and (f). Diabetes significantly increased the immunoreactivities of GFAP and VEGF and decreased PEDF. LBP treatment suppressed levels of GFAP and VEGF and elevated PEDF. GCL, ganglion cell layer; IPL, inner plexiform layer; INL, inner nuclear layer; ONL, outer nuclear layer. 0.05 compared with control group; 0.05, compared with model group.
