The rabbits were divided into three groups, which were supplemented with a 1% cholesterol diet (RC4, Oriental Yeast Co. Ltd., Tokyo, Japan; n=6), or a 1% cholesterol diet containing either 0.05% 2 (n=10) or 0.05% 3 (n=10) for 8 weeks. All rabbits were individually caged and maintained in a controlled facility at 20±2°C, relative humidity (55±5%) and a strict 12-h light/dark cycle. First, for the analysis of plasma lipids, the blood samples (3 mL), with ethylenediamine-tetraacetic acid (EDTA) as an anticoagulant, were obtained from the marginal vein of the ear, and centrifuged at 8000g for 10 min. Collected plasma was analyzed in an automatic blood chemical analyzer (Hitachi 7020, Japan) and the plasma concentrations of total cholesterol, HDL-cholesterol, and triglyceride obtained (Table 1). Then, for the evaluation of aortic fatty streak lesions, all rabbits were anesthetized with thiopental sodium (Choongwae Pharma Co., Seoul, Korea) and sacrificed by exsanguinations from the femoral artery. Immediately after opening the thoracic cavity, the aorta was excised, and adventitial tissue grossly adhering to the aorta removed. The aorta was then dissected longitudinally. The portion, a segment between the first and the sixth intercostal arteries, was fixed in 10% neutral buffered formalin for 1 day. The aorta was then placed in absolute propylene glycol for 2 min and stained with oil red O for 4 h. After washing, the extent of the oil red O-positive area was measured and expressed as a percentage of the internal surface using a computer-assisted morphometry system (Image Pro Plus, MD, USA).
