2、染色检查进行眼表评估。于第3个月时放射免疫分析法分别检测2组大鼠血清雌二醇、睾酮含量,HE染色观察泪腺上皮细胞形态,免疫组化染色法、WesternBlot法检测2组泪腺中IL一17A、IL一113、IL一6、TNF0l的表达。2组性激素质量浓度比较、炎症因子A值表达比较均应用独立样本t检验。2组各时间点的SIT结果比较采用重复测量资料两因素方差分析。结果实验组大鼠去卵巢后第3个月时,体内雌二醇浓度低于对照组(=一35.37,P<0.01),睾酮浓度低于对照组(一12.13,P<0.01)。2组各时期SIT检查未见泪液分泌减少、均
3、未见角膜荧光染色。HE染色见实验组泪腺腺泡萎缩,排列紊乱,胞质内酶原颗粒明显减少。泪腺IL.17A表达量2组比较实验组高于对照组(免疫组化法:回.56,P<0.o1;WesternBlot法:t=20.90,P<0.01)。余各因子表达量实验组也均高于对照组(免疫组化法:I1B:仁13.71,P4、鼠去卵巢3个月时性激素水平降低,未见明显眼表损害。但泪腺中炎症因子IL一17A、IL一1B、IL-6、TNF一0【的表达增加。【关键词】去卵巢大鼠;泪器;白细胞介素17A;白细胞介素1p;白细胞介素6;肿瘤坏死因子0【ExpressionofIL-17AinthelachrymalglandsofratsafterovariectomyZhongLei,ZhaugXiaofeng,XiaJing,XiaWei,SunZhengtai,WangYingming.Departmentof0phthalmology,theFirstA5、filiatedHospitalofSoochowUniversity,Suzhou215006,ChinaCorrespondingauthor:ZhaugXiaofeng,Email:zhangxiaofeng@sudcaedu.cn【Abstract】0bjectiveTostudytheexpressionofinflammatoryfactorsIL一17A,IL一113,IL-6andTNF—o【inthelachrymalglandsofovariectomizedratswhenthelevelofsexhorm6、oneschanges.MethodsThiswasanexperimentalstudy.TwentyhealthyfemaleSDratsweredividedrandomlyintoacontrolgroup(n-10)andanexperimentalgroup(n=10).Ovariectomywasperformedontheexperimenalgroup,whileashamoperationwasperformedonthecontrolgroup.ASchirmerItest(SIT)andcornealfl7、uorescencestainingwereperformedonbothgroupsbeforesurgeryandat1,2,and3monthsaftersurgery.TheresultswereanalyzedwiththerepeatedmeasurementANOVA.AcinarcellsfromthelacrimalglandswereexaminedbyHEstaining.Atthe3rdmonth,theconcentrationsofestrogenandandrogenweremeasuredbyra8、diationimmunoassaydetectionandwereanalyzedwithindependentsamplettests.TheexpressionsofIL·17A,IL一1B,IL一6andTNF—wereanalyzedbyimmunoh
