Effects of PCE on PDGF-BB and PDGFR-ß in the renal glomeruli. (A) Immunohistochemical staining of PDGF-BB and (B) PDGFR-ß. 400× magnification. Morphometric analysis of western blots showing (C) PDGF-BB and (D) PDGFR-ß expression in the renal cortex for each group. All data are expressed as the mean ± SEM (n=8). *P <0.01 vs. NOR group; #P <0.01 vs. DM group, and +P <0.01 vs. PCE-100 group.
