1、基础研究Jichuyanjiu《中国医学创新》第11卷第15期(总第297~])2014~5B陈汤对高脂饮食大鼠血脂及胰岛素二抵抗的影响术丁珊珊①康洁①张凌媛①沈建英①廖凌虹①【摘要】目的:观察化痰方(二陈汤)对高脂饮食大鼠血脂及胰岛素抵抗的影响。方法:3O只健康成年雄性大鼠按照随机数字表法分为正常组、高脂组和化痰组各1O只,正常组给予正常饲料喂养,高脂组和化痰组给予高脂饲料喂养14周,化痰组第11周起给予二陈汤灌胃4周。在第14周末进行葡萄糖耐量实验(OGTT)和胰岛素耐量实验(ITT),14周后处死大鼠,检测并比较各组血脂TC、TG的含量及第1
2、4周各组大鼠0G13"结果和ITT结果。结果:与正常组比较,高脂组大鼠血清中的Tc和TG含量均明显升高(P<0.01);与高脂组比较,化痰组大鼠血清中的TG含量明显降低(P<0.01),Tc有所降低,差异也有统计学意义(PO.05);糖负荷后,高脂组的各个时间点的血糖均明显高于正常组(P<0.05或P<0.01),而化痰组除了糖负荷后120min的血糖明显高于正常组外(PO.
3、05o腹腔注射胰岛素后,化痰组各时间点血糖下降幅度均明显高于高脂组,30min时高脂组血糖降低18%,而化痰组大鼠降低26%。结论:二陈汤能够降低高脂饮食大鼠血脂的含量,改善胰岛素抵抗,值得在临床上推广使用。【关键词】痰;高脂饮食;血脂;胰岛素抵抗EfectofErchenDecoctiononBloodFatandInsulinResistanceinRatsFedaHiglI—fatDiet/DINGShan—shan,KANGJie,ZHANGLing-yuan,etalJ/MedicalInnovationofChina,2014,11(1
