1、陕西中医学院硕士学位论文益气固表汤对小鼠哮喘发作及小鼠血清中IL--4,IL--13含量影响的实验研究姓名:张丽申请学位级别:硕士专业:中西医结合临床指导教师:刘晓萍201204中文摘要目的:本实验旨在通过饲养小鼠,给予灌胃补肺固表、益气扶正之“益气固表汤”提高小鼠机体免疫功能,20天后做小鼠哮喘激发实验,观察益气固表汤是否能延缓哮喘发作,且通过小鼠血清中IL-4,IL一13含量的变化评定“益气固表汤”是否有控制气道炎症反应的作用进而防止哮喘发作。为益气固表汤的临床应用提供理论依据。方法:相同条件下,普通饲料喂养小鼠,将40只小鼠适应性喂养3
2、天,然后分成空白对照组,盐水灌胃对照组,益气固表汤大剂量组,益气固表汤小剂量组,每组10只,空白对照组用普通饲料喂养,其余三组除正常普通饲料喂养外,盐水组灌胃生理盐水每次0.3ml,每日1次;益气固表汤大剂量组灌胃浓度为1.1129/ml的益气固表汤,每次0.3ml,每日1次;益气固表汤小剂量组灌胃浓度为0.5569/ml的益气固表汤,每次0.3ml,每日1次;共灌胃30天。实验第20天做哮喘激发,各组小鼠腹腔注射4%卵蛋白iml致敏,7天后将致敏小鼠逐个置于透明、密闭有机玻璃罩内,给予含1%卵蛋白的等渗盐水雾化吸入,每天1次,每次i0min
3、,共3天,观察各组小鼠出现哮喘症状的时间及检测血清中IL-4,IL-13含量的变化。结果:益气固表汤可延缓哮喘发作的时间,降低小鼠血清中IL一4,IL一13的含量,减轻哮喘发作时炎症反应,其中大剂量组效果最明显。(统计学有意义P4、:ThiSstudywasdesignedbyfeedingthemicegivengavagelungssolidtable,Qirighting“Yiqigubiaotang’’toimproveimmunefunctioninmice,themice20daysafterdoingprovocationexperiment,andobservationofQisolidformsoupcandelayanasthmaattack,andassessedbyserumIL一4,IL一13contentoftheroleof“Yiqigub5、iaotang"whetherthereiscontroltheairwayinflammationandthustopreventasthmaattacks.ProvideatheoreticalbasiSfortheclinicalapplicationofYiqigubiaotang.Method:Underthesameconditions,fedwithnormaldietmice,theadaptabilityofthe40micefedforthreedays,andthendividedintoblankcontrolgrou6、p,salinegavagecontrolgroup,QisolidformTanghigh—dosegroup,Qisolidformofsoup,smalldosegroupn=10,controlgroupwithnormaldietfeeding,theremainingthreegroupsinadditiontonormalordinaryfeeding,salinegroupfedwith0.3mlofsalineeachtime,onceaday:Qisolidformsoupirrigationoflarge—dosegro7、upfeedconcentrationof1.112g/mlQisolidformsoup,each0.3mldaily:Qisolidformsoup,smal1一dosegroupwerefedconcentrationsof0.556g/mlQisolidformsoupeach0.3ml,day1:werefedfor30days.The20daystodoprovocation,eachgroupofmicebyintraperitonealinjectionof4%eggproteinimlsensitized7dayssensi8、tizedmicewereindividuallyplacedintransparent,sealedorganicglass,giveisotoniccontai
