2、年新西兰大白兔,随机分为5组,分别为低剂量组、中剂量组、高剂量组、阳性对照组、阴性对照组,每组9只(18个膝关节)。采用内侧副韧带切断术和内侧半月板切除术建立骨性关节炎模型,术后次日即进行动物的药物灌胃,每日1次,每组各取3只动物分别于灌胃1周、2周、3周后取材。阳性对照组灌胃用等剂量的蒸馏水。采用墨汁染色的方法大体观察软骨损伤情况,使用光镜观察关节软骨组织学的变化;采用酶联免疫吸附法测定关节液中IL_18和TNF-a含量。结果:墨汁染色法和软骨组织学检查结果显示1周和2周后,低、中、高剂量组与阳性对照组之间均有显著性差异(P3、、中、高剂量组之间无显著性差异(P>o.05);3周后,低、中、高剂量组与阳性对照组之间均有显著性差异(Po.05),低、高剂量组之间有显著性差异(P4、子aApplicationofGlucosamineandChondroitinsulfateintheTreatmentoftheKn∞JointwithOst∞arthtitisinRabbitModelF仳xi竹。,Li佗Li竹7,V矿Pix孔以历7,Ho"y乱7,z矗口ng∥,i竹g。,Ⅵ亿佗g∥佗如P竹92,y孔c^口竹gfo竹91JJ碗s≠if“抛。厂s如r括A知dici佗P,黝i”gLf住iuP7ji毋T施i,’dH0s】bi£口f,BP巧i佗g,c玩i犯口JOD0832Th竹gS^口扎Ro竹gD口。P矗口7’7疗口cP“£ic5、口fI[勋.,Lfd,JIk竹g矶n竹,(珑幻2口06302DAbstmcto"PcffwTostudytheeffectofglucosamine(GS)andchondroitinsulfate(CS)onthei11juryofcart订ageandtheexpressionofinterleukin一1p(II,1p)andtumornecrosisfactora(TNF—a)ofthekneejointwithosteoarthritisinrabbitmodel.Mefhods45rabbitswererandomlydivide6、dinto5groups(9ineachgroup):nega—tivecontrolgroup,positivecontrolgroup,lowdosegroup,moderatedosegroupandhighdosegroup.Transec—tionofthemedialcollateralligamentandmedialmeniscectomyofbothkneeswasperformed.The2nddaypost_operation,GSandCSweretakenbyintragastricadministrationint7、reatmentgroup,andrabbitsweretreatedwithdistilledwaterinpositivecontrolgroup.Aftercontinuoustreatment,theanimalsweresacrificedonweek1,2and3.ThecartilagewasstainedwithIndianinktoevaluatetheseverityofcartilageinjury.Lightmicroscopewasusedtoinvestigatethemorphologicalchangeofca8、rtilage.TheexpressionofcytokinessuchasIL一1pandTNF一Ⅱinsynovialfluidwasdetectedbyenz
