摘要:

目的:比较“血瘀证”下急性心肌梗死模型与单纯急性心肌梗死模型大鼠心肌形态学、心肌酶学及血液流变学的变化,阐明在评价治疗胸痹心痛中药的药效学时使用单纯急性心肌梗死模型与“血瘀证”下急性心肌梗死模型之间的差异。方法:Wistar大鼠随机分为空白对照组、急性血瘀模型组、急性心肌梗死假手术组、单纯急性心肌梗死模型组及“血瘀证”下急性心肌梗死模型组(每组12只),在大鼠急性 “血瘀”情况下复制急性心肌梗死模型,检测各组大鼠心肌梗死面积 (MIS) 及血清天门冬氨酸氨基转化酶(AST)、肌酸磷酸激酶(CK)和乳酸脱氢酶(LDH)活性, 同时测定血小板黏附率(PAR)、血小板聚集率(PAG)、红细胞沉降率 (ESR)、红细胞压积 (HCT)、体外血栓长度、血栓干重与湿重以及血栓弹力图等参数,并与单纯急性心肌梗死模型进行对比。结果: ①“血瘀证”下急性心肌梗死模型与单纯急性心肌梗死模型大鼠在MIS,血清AST、CK及LDH活性,PAR及PAG方面差异无显著性(P>0.05);②“血瘀证”下急性心肌梗死模型大鼠ESR增加程度明显大于单纯急性心肌梗死模型组(P<0.05),HCT的增加程度差异则无显著性(P>0.05);③“血瘀证”下急性心肌梗死模型大鼠体外血栓干重及湿重的增加程度明显大于单纯急性心肌梗死模型组及急性血瘀模型组(P<0.05或P<0.01),体外血栓长度差异则无显著性(P>0.05);④“血瘀证”下急性心肌梗死模型大鼠的血栓弹力图r、k值的缩短程度及ma值的增大程度均明显大于单纯急性心肌梗死模型组(P<0.05),但与急性血瘀模型组之间差异无显著性(P>0.05)。结论:“血瘀证”下急性心肌梗死模型与单纯急性心肌梗死模型大鼠在血沉、体外血栓质量及血栓弹力图等指标上存在明显差异,在MIS、血清心肌酶学、HCT及血小板功能等指标上无明显差异,提示仅采用单纯的急性心肌梗死模型来评价中药的药效学而不考虑中医的证候是有缺陷的。

Abstract:

Abstract:Objective To  compare the changes of   myocardial morphology,myocardial enzymology and hemorheology  between the acute myocardial infarction models  with blood stasis and the simple acute myocardial infarction models in rats  and elucidate the difference between the acute myocardial infarction models in rats with blood stasis and the simple acute myocardial infarction models in evaluation of pharmacodynamics.Methods Wistar rats were randomly divided into  control,acute blood stasis model,acute myocardial infarction sham operation,acute myocardial infarction model and  acute myocardial infarction model with blood stasis groups.The acute myocardial infarction models under the status of the acute blood stasis in rats were built to determine the parameters of myocardial infarct size (MIS) and the activities of serum aspartate aminotransferase (AST),creatine phosphokinase (CK) and lactate dehydrogenase (LDH),at the same time,platelet agglutinate rate (PAR),platelet aggregation(PAG),erythrocyte sedimentation rate(ESR),hematocrit(HCT) and the length,the dry weight,the wet weight of the thromb in vitro were tested,the parameters of thrombelastogram were also be detected.Results ①When the acute myocardial infarction models with blood stasis in rats and the simple acute myocardial infarction models were comparatively studied,the results showed that there were no obvious differences between them in MIS,the activities of CK,AST and LDH,and PAR and PAG(P>0.05);② The increasing extent of the ESR of the acute myocardial infarction models with blood stasis in rats was much higher than that of the simple acute myocardial infarction models(P<0.05),but there was no obvious difference between them in HCT(P>0.05);③ The dry weight and the wet weight of the thromb in vitro of the acute myocardial infarction models with blood stasis in rats were  much heavier those  of the simple acute myocardial infarction models and the acute blood stasis syndrome models in rats(P<0.05 or P<0.01),but there was no obvious difference between them in the length of thromb in vitro(P>0.05);④ The increasing extent of the values of r,k and the reducing extent of the value of ma in the acute myocardial infarction models with blood stasis in rats were significantly higher than those in the simple acute myocardial infarction models(P<0.05),but there was no obvious difference between the acute myocardial infarction models with blood stasis and the acute blood stasis syndrome models in rats(P>0.05).Conclusion The obvious differences are showed in the parameters of blood sedimentation and the weight of the thromb in vitro and the thrombelastogram,but there are no obvious differences in the indexes of MIS,the myocardium enzyme in  serum,HCT and the index of  function of the blood plate when the acute myocardial infarction models with blood stasis and the simple acute myocardial infarction models are comparatively studied.The results  show that it is  defective to evaluate pharmacodynamics of traditional Chinese drug only with  simple acute myocardial infarction models.
