1、陜西中醫(yī)學院碩士學位論文強骨顆粒對去勢大鼠骨質(zhì)疏松模型骨形態(tài)計量學及骨組織TGF-β<,1>的影響姓名:陳世柱申請學位級別:碩士專業(yè):中醫(yī)骨傷指導(dǎo)教師:昝強20070401摘要目的:觀察強骨顆粒對去卵巢骨質(zhì)疏松大鼠骨形態(tài)計量學、骨組織TGF一13。的影響,以探討強骨顆粒防治骨質(zhì)疏松可能的作用機制。方法:40只6月齡sD雌性大鼠隨機抽取10只分為假手術(shù)組,剩余30只以雙側(cè)卵巢切除法復(fù)制骨質(zhì)疏松模型,手術(shù)造模3天后隨機分為3組:模型組、強骨顆粒治療組、雌激素對照組;12周后全部處死,采用免疫組化方法檢測脛骨上段骨組織TGF—B,水平,同時取大
2、鼠脛骨上段骨組織常規(guī)石臘切片HE染色方●法測定骨形態(tài)計量學參數(shù)。結(jié)果:1.大鼠造模12周時骨組織TGF_B。水平,強骨顆粒組、雌激素對照組均高于模型組(P<0.05)、接近假手術(shù)組(P>0.05);強骨顆粒組與雌激素對照組無明顯差異(P>O.05)。2.大鼠造模12周時脛骨上段骨組織形態(tài)計量學參數(shù),Tb.Th:強骨顆粒組、雌激素對照組均高于模型組(PO.05):Tb.Ar:強骨顆粒組高于模型組(P3、(P0.05)。結(jié)論:1.強骨顆粒能升高去卵巢骨質(zhì)疏松大鼠骨組織TGF—B,水平,使之接近正常組水平。2.強骨顆粒能改善去卵巢骨質(zhì)疏松大鼠骨組織形態(tài)學計量,起到通過改善骨形態(tài),達到預(yù)防和治療OP的目的。關(guān)鍵詞:強骨顆粒;骨質(zhì)疏松癥;大鼠;轉(zhuǎn)化樣生長因子一B。;骨組織形態(tài)計量學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
