1、陕西中医学院硕士学位论文强骨颗粒对去势大鼠骨质疏松模型骨形态计量学及骨组织TGF-β<,1>的影响姓名:陈世柱申请学位级别:硕士专业:中医骨伤指导教师:昝强20070401摘要目的:观察强骨颗粒对去卵巢骨质疏松大鼠骨形态计量学、骨组织TGF一13。的影响,以探讨强骨颗粒防治骨质疏松可能的作用机制。方法:40只6月龄sD雌性大鼠随机抽取10只分为假手术组,剩余30只以双侧卵巢切除法复制骨质疏松模型,手术造模3天后随机分为3组:模型组、强骨颗粒治疗组、雌激素对照组;12周后全部处死,采用免疫组化方法检测胫骨上段骨组织TGF—B,水平,同时取大
2、鼠胫骨上段骨组织常规石腊切片HE染色方●法测定骨形态计量学参数。结果:1.大鼠造模12周时骨组织TGF_B。水平,强骨颗粒组、雌激素对照组均高于模型组(P<0.05)、接近假手术组(P>0.05);强骨颗粒组与雌激素对照组无明显差异(P>O.05)。2.大鼠造模12周时胫骨上段骨组织形态计量学参数,Tb.Th:强骨颗粒组、雌激素对照组均高于模型组(PO.05):Tb.Ar:强骨颗粒组高于模型组(P3、(P0.05)。结论:1.强骨颗粒能升高去卵巢骨质疏松大鼠骨组织TGF—B,水平,使之接近正常组水平。2.强骨颗粒能改善去卵巢骨质疏松大鼠骨组织形态学计量,起到通过改善骨形态,达到预防和治疗OP的目的。关键词:强骨颗粒;骨质疏松症;大鼠;转化样生长因子一B。;骨组织形态计量学EffectsofQianggugranuleonthehistomorphologyofboneandtheexpre4、ssionofTGF—B1inbonetissueoftheovariectomizedratsABSTRACTobjective:TheresearchWaStoinvestigatetheeffectsofQianggugranuleonTGF—B1inbonetissue,thehistomorphologyofboneinratstofurtherexplainthemechanismofQianggugranuleonpreventingandtreatingosteoporosis.Methods:Tenratswereran5、domlychosedfromfortyfemaleSprague—daweley(SD)ratsaged6month.Theleftthirtyratswererandomlydividedinto3groups3daysafterovariectomy:groupsofosteoporoticanimalmodelwithnormalphysiologicalsaline,treatinggroupsofosteoporoticanimalmodelwithQianggugranule,treatinggroupofosteoporo6、tieanimalmodelwithconjugatedestrogen.After12weeks,allratsweresacrificed.TheexpressionofTGF—BllevelinbonetissueWaSdetectedbyimmunohistochemistrymethod.Thepmximaltibiawastakenandparaffinsectionwasmade.ThesamplesweredyedwithHE,thehislomorphometricparametersweremeasuredbyadig7、itzingimageanalysissystem.,Results:1.ThelevelofTGF-B1inbonetissuein12weeksafterovariectomyoftreatinggroupswithQianggugranuleandconjugatedestrogenwereallhigherthangroupsofosteoporoticanimalmodel口O.05).Effectsoftreatinggroupswi8、thQianggugranuleWasclosetogroupsofconjugatedestrogenfP>O.05).2.Thehislomorphometricpavdmetersoft
