1、大黄、紫苏提取液对大鼠颈总动脉挤压后内膜增生防治作用的研究摘要:目的研究大黄提取液、紫苏梗、籽、叶提取液对大鼠颈总动脉挤压后内膜增生的防治作用。方法正常sD大鼠56只,随机分为正常对照组、动物模型组、实验用药组(阿司匹林组、大黄组、紫苏梗、紫苏叶组、紫苏籽组)。除正常对照组外,其它各组均采用颈总动脉挤压法建立血管内膜增生模型。术后30天取颈总动脉,进行颈总动脉通畅率和组织形态学结构观察,并用H.E染色法、弹性纤维和胶原纤维双重组合染色法、图像分析系统、SPSSl0.0对颈总动脉进行染色、测量和数据统计分析。结果1、与正常对照组相比,动物模型组左侧颈总动脉发生了明显的内膜增
2、生,管腔被细胞所填充,血流不畅,血管管壁增厚,结构异常,大量弹性纤维和胶原纤维在管壁内沉积,排列紊乱。2、阿司匹林组和动物模型组血管壁组织结构基本相似,管壁正常结构消失,血管腔阻塞,(内膜+中膜)占有率、管腔横切面积占有率差异均不显著(P>O.05)。3、大黄组和紫苏梗、籽、叶组与动物模型组相比,大鼠左侧颈总动脉内膜增生均明显减轻,管壁变薄,管腔光滑,内膜增生减小,内膜厚度明显变薄,中膜平滑肌、弹性纤维排列规则,外膜由结缔组织组成。(内膜+中膜)占有率差异极显著(P<0.01),管腔横切面积占有率差异显著(P3、后内膜增生防治效果接近,管壁厚度和管腔面积相似,(内膜+中膜)占有率、管腔占有率差异均不显著(P>O.05)。结论大鼠血管内膜增生模型的建立是成功的;阿司匹林对大鼠颈总动脉挤压后内膜增生没有明显的防治作用;大黄提取液、紫苏梗、籽、叶提取液对大鼠颈总动脉挤压后内膜增生均具有一定的防治作用,防治效果相似。关键词大黄紫苏大鼠颈总动脉内膜增生血管平滑肌细胞弹性纤维ResearchontheFunctionoftheExtractionsofPerillaFrutescensandRhubarbinPreventingandCuringtheIntimaHyperplasiaofR4、at’SCarotidArteryafterBeingSqueezedAbstract:Objective:TostudythefunctionoftheextractionsofPeriUaFrutescensandRhubarbinpreventingandcuringtheintimahyperplasiaofRat’SCarotidArteryafterBeingSqueezed.Methods:ThehealthySDratsweredividedintothreegroupsatrandom,thecontrolgroup,themodelclusterand5、theexperimentalgroupwhichincludedtheaspirinrow,theRhubarbrow,thePerillaFrutescensstalksro、Ⅳ.thePerillaFrutescensIeavesrowandthePerillaFrutescensseedsrow.Excludingthecontrolgroup,theintimahyperplasiamodelswergfoundedintheothertwoclusters.Thirtydayslater,theobservationsofthehistomorphologya6、ndthestructurewerecarriedoutontheleftandtherightcarotidarteriesofeachrat.AndthatthestatisticalanalysiswasproceededthroughthewaysHEstain,VGstainandimagineanalysis.Results:1,Comparingwimcontrolgroup,theintimahyperplasiaoftheleftcarotidarterywasobviousinthemodelcluster.ThevesseIcavityfilledw7、ithvasculaendothelialceils.Thethickingtookplaceinthewallofthearterywherealotofelasticfibersandcollagenousfibersdepositedmussily.2-Thestructureofthewallofthearteryintheaspirinrowwaslikenearlywinlthatinthemodelcluster.Thenormaltextureofthewallofthearterydisappeared.Th
