目的:探索一种快速、简便建立SD大鼠动脉粥样硬化模型的方法。方法:30只雄性SD大鼠随机分成正常对照组(A组)、高脂饮食联合维生素D3组(B组)、复合方法造模组(C组)。A组喂食普通饲料,B组给予高脂饮食和维生素D3(VitD3),C组在高脂饮食的基础上给予VitD3腹腔注射、丙基硫氧嘧啶(灌胃)、免疫损伤法、FeSO4(饮水)制备大鼠动脉粥样硬化模型,实验4周后处死,光镜下观察主动脉的病理变化;检测血清总胆固醇(TC)、甘油三酯(TG)和低密度脂蛋白(LDL)。结果:光镜下观察,A组SD大鼠未出现动脉硬化改变,B组仅出现轻度动脉硬化病变,C组出现典型动脉粥样硬化改变;A组血清TC、TG、LDL分别为(2.82±0.26)mmol/L,(1.69±0.31)mmol/L,(1.62±0.26)mmol/L,B组分别为(3.68±0.41)mmol/L,(0.95±0.21)mmol/L,(2.19±0.35)mmol/L,C组分别为(4.33±0.28)mmol/L,(0.99±0.13)mmol/L,(2.19±0.24)mmol/L,C组与A组比较升高显著(P<0.01),C组与B组比较升高明显(P<0.05)。结论:复合造模方法比高脂饮食联合VitD3成模效果好,可以快速简便造成大鼠动脉粥样硬化模型。

Objective To explore a rapid ,simple method of atherosclerosis model in SD rats. Methods Thirty healthy male SD rats were randomly divided into a normal control group(A), a high-fat diet with vita?min D3 group(B),and a multi-factor group(C). Group A had basic food ,group B had a high-fat diet and intra?peritoneal injection of VitD3, group C had high-fat diet with intraperitoneal injection of VitD3, lavage of propyl?thiouracil, immune damage, and FeSO4 treatment. These rats were sacrificed after 4 weeks experiment to observe the pathological changes of the aorta and to detect serum total cholesterol(TC), triglyceride(TG) and low density lipoprotein. Results In optical microscopy ,group B had mild atherosclerosis lesions, and group C had typical atherosclerosis. Serum TC 、TG and LDL of group A were correspondingly (2.82 ± 0.26), (1.69 ± 0.31),(1.62 ± 0.26) mmol/L; group B were(3.68 ± 0.41), (0.95 ± 0.21), (2.19 ± 0.35) mmol/l; and group C were (4.33 ± 0.2), (0.99 ± 0.13), (2.19 ± 0.24) mmol/L correspondingly values in Group C were increased significantly as compared with group A and group B. Conclusion Compared with the high-fat diet with vitamin D3, the multi-factor method is quicker and easier for induction of rat model of atherosclerosis.
