Effects of berberine (BBR) on the aorta of rats fed with a high-fat diet. After BBR treatment for 16 weeks, rats were killed after a 14-hour fast. Histological analysis of the aorta of the HFD-fed rats treated with vehicle (C group) or BBR (B group). The aorta sections were stained with hematoxylin and eosin (A-D) or with Sudan Ш (E-I) to evaluate the pathologic structures. Representative photographs are shown. A-B, E-F: Photographs are at × 50 magnification, C-D, G-H: Photographs are at × 400 magnification.
