2、性胃炎的镜下病理表现及蛋白表达bax、bcl.2的影响,从而阐述黄连温胆汤对慢性胃炎的治疗机理,为黄连温胆汤在临床治疗慢性胃炎的应用提供一定的现代科学依据。方法:将sD大鼠随机分成6组,每组10只,即空白组对照组、模型组、西沙必利组、黄连温胆汤高剂量组、中剂量组、低剂量组,除空白组外,其余各组均采用脱氧胆酸钠、乙醇溶液结合湿热环境、饮食不节等综合方法诱发大鼠慢性胃炎脾胃湿热型模型,造模完成后,空白对照组、模型组给予生理盐水灌胃,其余各组均给予相应的药物灌胃,实验期间观察记录大鼠的一般情况,末次给药后处死大鼠,肉眼下观察胃粘膜损害,并进行镜下病理组织学观
3、察,对空白组、模型组、西沙必利组、黄连温胆汤高剂量组进行免疫组化分析,观察bax、bcl2蛋白的表达情况。结果:与模型组比较,除空白组外各组大鼠胃粘膜的炎症程度均有所减轻,西沙必利组、黄连温胆汤高剂量组能降低bax阳性表达率,增加bcl.2阳性表达率,与模型组比较均有统计学差异(P<0.05);与西沙必利组比较,黄连温胆汤高剂量组能显著改善大鼠胃粘膜损伤程度,降低bax阳性表达率,增加bal一2阳性表达率,两组比较有统计学差异(P4、缓胃粘膜细胞的炎症进程,阻断胃粘膜的损伤进程,加快胃粘膜的修复。关键词黄连温胆汤大鼠慢性胃炎脾胃湿热证大鼠慢性胃炎造模bcl一2bax成都中医药大学硕士论文AbstractPurpose:ThroughtheobservationofHuanglianWendanDecoctiononexperimentalchronicgastritisinratswithspleenstomachdampheattypetherapeuticeffect,Investigationonthechronicgastritisbyendoscopicandhistop5、athologicalmanifestationsandproteinexpressionofBax,bcl一2effecttoelucidatetheHuanglianWendanDecoctionintreatmentofchronicgastritisapplicationprovidesamodernscientifiCbasis.Methods:TheSDratswererandomlydividedinto6groups,eachgroupof10,Namelytheblankgroup,modelgroup.cisapridegroup,6、HuanglianWendanDecoctionhighdosegroup,middledosegroup,lowdosegroup,excepttheblankgroup.Othergroupsareusingsodiumdeoxycholate,ethanolsolutioncombinedwiththehotandhumidenvironment,improperdietandothercomprehensivemethodinratsinducedbychronicgastritisofSpleen·stomachdamp-heattypemo7、del.Modeledafter,blankcontrolgroup,modelgroupweregivensalinelavage,othergroupsweregiventhecorrespondingdruggastricperfason,moldingandadministrationduringtheobservationrecordsofratsingeneral.Thenakedeyeobservationofgastricmucosadamage,andwithafixativefixedspecimens,histopathologi8、calobservationofendoscope.Andtheblankgroup,mode
