Western blot assay for VEGF and bFGF protein expression in the brain.

Expression was calculated as the ratio of the optical density of the target protein to that of GAPDH. Values were presented as the mean ± SD (n = 10; one-way analysis of variance followed by Student's t-test). *P < 0.05, vs. sham group; #P < 0.05, vs. VD model group; †P < 0.05, ††P < 0.01, vs. 50 mg/kg PGE group. PGE: Panax ginseng extract; VD: vascular dementia; VEGF: vascular endothelial growth factor; bFGF: basic fibroblast growth factor.
