2、Alien’S打击器制作大鼠SCI模型.将造模成功的96只大鼠随机分为模型组、甲基强的松龙组(下称甲强龙组)、脊伤颗粒组。分别给予假手术组、模型组生理盐水灌胃,甲强龙组尾静脉注射药物,脊伤颗粒组予以相应药物灌胃。在给药后1、3、7、14d的4个不同时间点采用BBB行为学功能评分;再分批处死大鼠,取出SCI组织用HE染色观察其病理变化,用免疫组化染色检测Caspase一3表达阳性细胞,原位末端标记法(TUNEL法)标记凋亡细胞。结果(1)BBB运动功能评分方面,与假手术组比较,模型组评分低(P3、尸<0.05);与甲强龙组比较,SCI后1、3d,脊伤颗粒组评分偏低,(P<0.05),SCI后7、14d脊伤颗粒组评分偏高(P4、伤颗粒;半胱氨酸蛋白酶~3;细胞凋亡;运动功能评分;大鼠[中图分类号)R285.5[文献标识码]A[文章编号]doi:10.3969/j.issn.1674—070X.2015.O1.006.022.04EffectofJishangParticleontheExpressionofCaspase-3andMotorFunctionScoreinRatsthAcuteSpinalCordInjuryLIBd,DINGJianhuiZENGShufanf,LUOJuli2,KUANG‰ZHOUChangzhen(.HunanUniversityof5、ChineseMedicine,Changsha,Hunan410208,Chinc~2.TheFistAfiliatedHospitalofHunanUni—versityofChineseMedicine,Changsha,Hunan410007,China)[Abstract]ObjectiveTostudytheefectofJishangparticleontheexpressionofCaspase一3andthemotorfunctionofratswithspinalcordinjury(sci)。Me~ods32ratswere6、selectedrandomlyascontrolgrouponly,therestofthe118ratswerebuiltasSCIratroodelsbyusingmodifiedAllenbeater.96successfulmoldingratswerelandoln—lydividedintomodelgroup,methylprednisolonegroup(MPgroup)andJishangparticlegroup.Theshamoperationandmodelgroupwereperfusedwithnormalsalin7、e.TheMPgroupwasinjecteddrugstocaudalveinofrats.TheJishangparticlegroupwasgivenbygavagecorrespondingmedicine.Aftergivenmedicines,theBBBLocomotorRatingScalewasusedatf0urdiflferentpointintime:1,3,7and14d.TheratswerekilledandtheirSCItissuesweretakenout.Thepathologicalchangeofrats8、wasobservedbyHEstainingassay.TheCaspase-3positivecelsexpressionwasde
