2、盐水,注射完成后在4周、8周、12周分批处死,取软骨进行组织学观察、电镜检查、凋亡染色和葡糖氨基聚糖(Glycosaminoglycan,GAG)含量测定。结果肉眼观察:随着时间的延长,关节软骨退变程度加重。光镜下:对各标本进行组织学评分,关节软骨退变采用组织.组化评分标准(Mankin,1971),实验组与对照组比较,P值3、不规则,胞膜上突起消失,核膜不完整,内质网扩张明显,细胞器数目减少,可见脂滴存在,细胞坏死、溶解多见。GAG测定结果:对照组蛋白多糖含量无明显变化,实验组在不同时期的GAG含量均明显低于对照组,p<0.05;实验组8周时最为明显,12周组虽低于8周组,二者之间却无显著差异性。结论:uPA能导致关节软骨退变。uPA能使关节软骨蛋白多糖合成下降,导致关节软骨破坏。uPA与关节软骨细胞凋亡之间没有直接相关的联系。关键词:骨关节炎,关节软骨,尿激酶型纤溶酶原激活物,蛋白多糖论文类型:B(应用研究)TheExperimentResearchThatuPA‘ToSufferFromRelativity4、WithArthritisDiseasePostgraduate:HeBin(Surgery)Advisor:professorShiChenhniAbstract:PurposeToinvestigatetherelationshipbetweenurokinase—typeplasminogenactivatorandthedegenerationofcartilageinosteoarthritis.Methods42NewZealandwhiterabbitsweredevidedinto2groupsasrandom,24experimental,18matchedcontr015、.TheexperimentalanimalswereinjectedintraarticularlywithuPAinrightkneejoint,controlanimalswereinjectedwiththesamedosefonormalsaline.Allanimalswerekilledin4,8,12weeksrespectivelyaftertheinjections.Therabbitcartilageweretakentocarryonhistologyobservation,electricitymirrorcheck,theapoptosisdyeandGlyco6、saminoglycan(GAG)wasextractedfromcartilageanddetectedwithbiochemicaltechniques.Resultscartilagedestructionwaspositivelycorrelatedwiththetime.ThemethodWasgiventovalueaboutthehistologygradepointtoeachspecimeninthelightmirrorandtheorganization—histochemicationstandard(Mankin,1971)wasgiveninthejointca7、rtilagedegradation.Theresultshowscomparingbothoftheexperimentanimalsandthematchedcontrols,thereweresignificantdifferencesbetweenofthem.AnditdoesSOintheexperimentgroups.Theapoptosisdyesweredetectedbyallanimalsthat
