【摘要】 目的:采用对Balb/c小鼠反复腹腔注射CVB_3m病毒的方法,复制病毒性心肌疾病模型,观察益气养阴,活血化瘀法对病毒性心肌疾病小鼠心肌Fas、FasL蛋白表达水平的影响,从细胞水平来探讨其作用机制,并为中药复方防治病毒性心肌疾病提供依据。方法:将210只Balb/c小鼠,随机分为4组,空白对照组30只,模型对照组、中药高剂量组、中药低剂量组各60只。采用反复腹腔注射CVB_3m病毒的方法复制病毒性心肌疾病模型。常规方法观测小鼠心脏质量指数变化;采用HE、VG染色法观察各组心肌病理形态、心肌胶原组织及超微结构的变化;采用免疫组化法检测Fas、FasL蛋白表达。结果:1.与空白对照组相比模型对照组、中药高、低剂量组小鼠心脏重量/体重比值均明显增高（P＜0.05）;与模型对照组相比,中药高剂量组、中药低剂量组小鼠心脏重量/体重比值均明显降低（P＜0.05）。2.与空白对照组相比模型对照组、中药高、低剂量组小鼠心肌病理形态及超微结构异常;与模型对照组比较中药高、低剂量组均有不同程度的减低。3.与空白对照组比较模型对照组、中药高、低剂量组心肌组织内均有不同程度Fas、FasL蛋白的表达;与模型对照组比较中药高、低剂量组阳性表达明显降低（P＜0.05）,中药高剂量组与中药低剂量组间无显著差异（P＞0.05）。结论:Balb/c小鼠反复腹腔注射CVB_3m病毒的方法能成功的复制病毒性心肌疾病模型,以益气养阴、活血化瘀法组成中药复方能改善其心脏质量指数和病理形态学及超微结构的变化,并能够下调病毒性心肌疾病小鼠Fas、FasL蛋白表达,这可能是益气养阴、活血化瘀法组成中药复方防治病毒性心肌肌病的作用机制之一。更多还原

【Abstract】 Objective:To investigate the effect of the method of yi qi yang yin huo xue hua yu on the rat model of viral myocardial disease by observing the expression of Fas/FasL protein in cardiac muscle.Methods:Replicated the animal models of the viral myocardial disease with the method of injecting the CVB_3mvirus to the peritoneal cavity of the Balb/c rats for 6 times.210 Balb/c male rats were divided into 4 groups at random:blank group,model group,low dose traditional Chinese medicine group and high dose traditional Chinese medicine group.The blank group has 30 rats.The other three group has 60 rats each.Then observe the change of pathomorphology in the cardiac muscle tissue on the 90th day of the experiment.And immunohistochemistry method was used to exam the expression of Fas/FasL protein in cardiac muscle.Results:1.Compared with the blank group the cardiac weight index of the other three groups is higher,and compared with the model group the cardiac weight index of low dose and high dose traditional Chinese medicine group is lower.2.Compared with the blank group the changes of the pathomorphismand and the ultra-structure in other three groups is abnormal.,and compared with the model group the changes of the pathomorphismand and the ultra-structure of low dose and high dose traditional Chinese medicine group is lower.3.Compared with the blank group there are the expression of Fas/FasL protein in every other group’s cardiac muscle,and compared with the model group the expression of Fas/FasL protein in cardiac muscle in the low dose and high dose traditional Chinese medicine group is lower.Conclusions:1.The prescription on the base of the method of yiqiyangyinhuoxuehuayu can lower the cardiac weight index and lower the changes of the pathomorphismand and the ultra-structure in cardiac muscle.The prescription can reduce the expression of Fas/ FasL protein in cardiac muscle that maybe cure viral myocardial disease.更多还原
