Results of immunohistochemical study. a. Representative examples of immunohistochemical staining of E-sel (A-E), ICAM-1 (F-J), VCAM-1 (K-O) and MCP-1 (P-T) in the first portion of rabbit aortas (amplification ×400). b. Immunohistochemical score (IHS) of rabbit aorta sections. Control: rabbits fed on normal diets; Model: rabbits fed on high-cholesterol diets; Fenofibrate: rabbits received high-cholesterol diets plus fenofibrate (12 mg/kg); Kaempferol-H: rabbits received high-cholesterol diets plus kaempferol (150 mg/kg); Kaempferol-L: rabbits received high-cholesterol diets plus kaempferol (30 mg/kg). Each bar represents mean± SD (n = 6). *P<0.05, **p < 0.01, compared with model group; ## p < 0.01, compared with control group.
