Immunohistochemical (A) and Western blotting (B) analysis of 4-HNE expression. Densitometric analysis of Western blots (C) in aorta of D-gal-induced aging rats with high fat diet are shown. Y-C: Young control group, A-C: Aging control group, AHF: Aging with high fat diet group, AHF-EX: AHF with exercise training group, AHF-EX+RG: AHF-EX with Korean red ginseng, AHF-RG: AHF with Korean red ginseng. ^*P < 0.05, ^**P < 0.01 vs Y-C, A-C, ^†P < 0.05 vs AHF. Magnification = ×400, Bar = 200 µm. Values are means ± SEM (n = 8).
