2、低、中、高剂量组,分别加入50、100、200mg/ml黄芪注射液,以及10mol/LAngⅡ,共同培育2d。用四甲基偶氮哇盐法测定各组细胞增殖情况,ELISA法测定培养上清TGF—p分泌情况。结果各组间细胞增殖率差异有统计学意义(F=71.84,P=0.000);Ang1I组的细胞增殖率明显升高,与其余各组比较均有统计学意义(P均<0.05);Ang17联合黄芪后,随着黄芪剂量的逐渐增加,细胞增殖率逐渐下降,差异均有统计学意义<0.05)。各组间TGF-D。分泌量差异也有统计学意义(F=786.81,P=0.000);黄芪低、中、高剂量组的TGF-6分泌量均低于对照组
3、,差异有统计学意义(P均<0.O5);AngⅡ组的TGF—p。分泌量为各组中最高,与其余各组比较均有统计学意义(P均4、onandtransforminggrowthfactorp1productionofcardiacfibroblastsRUANTao.HEXuehuaLIULiping,YUANYonghua.PANLi,LIUZhenyu.LUOJianhon~HUShaya(DepartmentofPediatricCardiology,TheFirstAfiliatedClinicalCollege,HunanNormalUniversity,Changsha410005,Hunan,China.)Abstract:ObjectiveToobservetheefectofAs5、tragalusmembranaousonangiotensinII(AngII)-inducedtransform—inggrowthfactorDl(TGF)productionofcardiacfibroblasts.MethodsCardiacfibroblastswereculturedinvitro.Cellswereallocatedinto3groups:controlgroup,Astragalusmembranaousgroups(50,100,200mg/m1),AngIIgroup(10—7mol/L)andAngII/Astragalusmem6、branaousgroups(50,100,200mg/m1).Theproliferationofeachgroupwastestedbymethylthiazolyltetrazoliummethod.TGF—plwasmeasuredbyELISA.ResultsTheproliferationofcardiacfibroblastshadsignificantdiferencebetweeneachgroups(71.84,=0.ooo).TheproliferationofcardiacfibroblastswithAngIIstimulationwashig7、herthanthatofcellswithoutAngIIstimulationfP
