Protective effect of SFN on diabetes-induced aortic fibrosis. Aortic fibrosis was examined by immunohistochemical staining for the expression of CTGF (a) and TGF-β1 (b), followed by semiquantitative analysis. Data were presented as means ± SD (n = 6); *P < 0.05 versus corresponding Ctrl; # P < 0.05 versus corresponding DM. Bar = 50 μM.
