1、兰州大学硕士学位论文促性腺激素释放激素类似物预防化疗对性腺损伤研究摘要目的:探讨促性腺激素释放激素类似物(GnRHa)在减轻化疗所致的大鼠卵巢功能损害中的作用方法:选用2.3月龄Wister雌性大鼠40只随机分为四组,分别为正常对照组、CTX组、GrdtHa组、CTX+GnRHa组,正常对照组:0,9%生理盐水l111l每天腹腔注射,连续20天。GnRHa组:阿拉瑞林每日5嚏溶于lml0.9%的生理盐水中皮下注射,连续给药20天。CTX组:O.9%生理盐水lml连续腹腔注射lO天后,环磷酰胺(CTX)20mg,Kg一1,d.1,腹腔注射连续给药10天。CTX+GnRHa组:阿拉瑞林
2、5垤溶于lml0.9%生理盐水中连续皮下注射10天后,腹腔注射CTX20mg.kg-1.d-1,连续10天。用药后间情期处死处死大鼠,对大鼠及其卵巢、子宫称湿重和进行组织形态学观察,并留取血清2ml采用放射免疫方法对四组大鼠卵泡生成素(FSH)、雌二醇(E2)进行测定并进行比较。结果:组织形态学可见GnRHa能明显改善CTX对卵巢、子宫的损害;C2"X细与难常对照组比较FSH升高、E2的水平明显降低(tP3、大部分初级卵泡,从而总的卵泡数增加。结论:CrnRHa能提高大鼠体内的FSH、E2的水平,使卵巢,子宫的重量增加,组织形态改善,减轻CTX对大鼠卵巢、子宫的损害,从而保护卵巢储备功能。关键词:促性腺激素释放激素类似物(GnRHa);环磷酰胺(cTx);卵巢功能【中国图书馆分类法分类号】R711.75——兰型查堂堡主堂堡堕塞ABSmCTObject:ToinvestigatetheeffectofGnRHainpreventingofChemotherapy—inducedOvarianfailureinrats.Methods:2-3monthsyoungfemaleWisterr4、atswererandomizedintotburgroups,thenormalcontrolgroup,CTXgroup,CmRHagroup,CTX+GnRttagroup.Radioimmuoassaywasusedtoanalysebloodleveloffollicle—stimulatinghormone(FSH)andestradiol(E2)amongfjllrtreatment.Theovaryweightandhistomorphologicalfeaturesofovaryanduteruswerealsoobserved.Results:Ascompare5、dwit}lthenormalcontrolgroup.1evelsofFSItintheCTXgroupweresignificantlyincreased,E2weresignificantlydecreased(p<0.01),andwei曲tofovaryanduterusofCTXgrouparemorethanthatofthecontrolgroup.CTXtreatmentproducedasignificantreductioninthetotalnumberoffollicle.GnRHareducedthenumberofmedium—largefollicl6、esandincreasedthenumberofsrnallones,thetotalnumberoffolliclesareincreased.ChronicGnRHatreatmentresultedinpreservingofmostsmallfolliclesandincreasedthetotalnumberoffollicles.AlarilionshowedmarkedlyeffectsonimprovingtheovationanduterinemorphologicalconstructionofratsConclusions:GnRHacouldelevate7、thelevelofFSH、E2,increasetheweightandimprovethehistomorphologicfeaturesofovariananduterusinrats,itdemonstratedthatGnRHacarlreducingthechemotherapy—inducedovariandamage.keywords:GnRHagonist;CTX:functionofovarianⅡ原创性声明y732039本人郑重声明:本人所呈交的
