1、中华中医药杂志(原中国医药学~)2014年6月第29卷第6期CJTCMP,June,2014,Vo1.29,No.6·180l·论著·脑出血对大鼠前脑侧脑室室管膜下区细胞的影响及三七总皂苷的作用白华静,刘峻崎,李巾伟,司银楚(北京中医药大学基础医学院,北京100029)摘要:目的:观察脑出血对大鼠前脑侧脑室室管膜下区(SVZ)细胞的影响及三七总皂苷的作用。方法:采用Wistar成年雄性大鼠,用胶原酶注入尾壳核建立脑出血模型,应用免疫组化方法观察脑出血后侧脑室SVZ细胞增殖细胞核抗原(PCNA)、B一1I型微管蛋白(Tuj一1)、胶质原纤维
2、酸性蛋白(GFAP)的表达,以及碱性成纤维细胞生长因子(bFGF)的表达与活化,研究侧脑室SVZ细胞的增殖、分化及三七总皂苷的作用。结果:通过连续切片的免疫组化结果显示脑出血后损伤侧侧脑室SVZ的PCNA、GFAP、Tuj—l和bFGFI~H性细胞表达增强,给予三七总皂苷干预后,给药组上述阳性细胞个数显著增多,与模型组比较具有显著性差异(P<0.05,P3、金资助:国家自然科学基金面上课题(No.81373830)EffectofcerebralhaemorrhageandpanaxnotoginsengsaponinsonsubventricularzonecellsoflateralventricleinratforebrainBAIHua~ing,LIUJun—qi,LIJin—wei,SIYin—chu(CollegeofBasicMedicalSciences,BeijingUniversityofChineseMedicine,Beijing100029,China)Abstra4、ct:0bjective:Toobserveeffectofcerebralhaemorrhageandpanaxnotoginsengsaponins(PNS)onsubventricularzone(SVZ)cellsoflateralventricleinratforebrain.Methods:CerebralhemorrhagemodelwereestablishedbyinjectingwithcollagenaseoncaudatenucleusofadultmaleWistarrats.Theexpressionofpro5、liferatingcellnuclearantigen(PCNA),Tuj一1,glialfibrillaryacidicprotein(GFAP)andtheexpressionandactivationofbasicfibroblastgrowthfactor(BFGF)weredeterminedbyimmunohistochemicalmethodonSVZcellsoflateralventricleaftercerebralhaemorrhage.Tostudytheproliferationanddifferentiati6、onofSVZcellsoflateralventricleandtheeffectofPNS.Results:Throughtheimmunohistochemicalresultsofserialsections,theexpressionofPCNA,GFAP,Tuj一1andbFGFpositivecellsincreasedinSVZoflateralventricleaftercerebralhaemorrhage.AftertheadministrationofPNS,thenumbersofpositivecellsint7、hetreatmentgroupincreasedsignificantly,thereweresignificantdifferencescomparedwithmodelgroup(P<0.05,P<0.O1).Conclusion:CerebralhemorhagecouldactivateneuralstemcellsinSVZoflateralventricleinratsforebrainandpromoteproliferationanddifferentiation.PNScouldpromotetheaboveeffec8、tsthroughenhancingtheforebrainBFGFexpression.Keywords:Cerebralhemorrhage;Subventricularzonecells
