1、成都中医药大学2009级硕士学位论文中文摘要目的:通过观察白术、茯苓及白术茯苓汤对模型动物胃肠道形态学的变化与肠道推进功能、水通道蛋白(AQP)、电解质等的影响,从水液代谢角度初步揭示其治疗脾虚泄泻的作用机理。方法:①采用破气苦下饥饱失常法复制脾虚泄泻模型;②应用炭末推进法测定大鼠胃残留率及小肠推进率;③电解质分析仪测定血清电解质水平;④光学显微镜观察胃肠组织形态变化;⑤酶联免疫法测定空肠和结肠黏膜AQP3、AQP4含量。比较研究白术、茯苓及白术茯苓汤治疗脾虚泄泻的作用,并初步探讨其作用机理。结果:①光学显微镜观察显示,各治
2、疗组对损伤均有不同程度的改善:其中空肠部位以茯苓组最理想;结肠部位均明显改善;直肠部位以白术茯苓组和白术组最理想。②各治疗组胃残留率均下降,其中以白术茯苓组为显著(P3、.05)。(2)AQP4:在空肠部位均升高,其中以白术茯苓组为显著(P<0.05);在结肠部位均升高,但各治疗组无显著差异(P>0.05)。结论:自术、茯苓及白术茯苓汤治疗脾虚泄泻的作用机制可能有二:其一,修复肠道黏膜损伤,改善通透性,促进水液吸收;其二,调控AQP3表达、恢复血清电解质平衡、促进肠道炎性病理渗出物与渗透性溶质排出,改善肠道水液代谢功能。其中,白术茯苓汤对上述机制综合调节最佳,与单味药比较体现了协同增效的“相须相使”。关键词:白术茯苓白术茯苓汤脾虚泄泻水液代谢成都中医药大学2009级硕士学位论文ABSTRAC4、TObjective:Toobservebfiizhfi(RhizomaAtractylodisMacrocephalae),ffiling(Pofia)andFflLingBhiZhfiTang(RhizomaAtractylodisMacrocephalaeandPoriaDecoction)onthechangesinthegastrointestinaltractmorphologyinanimalmodelsandintestinalpropulsion,aquapofin(AQP),electrolyte,etc5、.,revealeditsmechanismoftreatingspleendeficiencydiarrheafromtheperspectiveofthewatermetabolism.Methods:@usingspleendeficiencydiarrheamodelbyirregulardietandbreakingqiandeliminationwiththebitter-propertymedicinals.②Theapplicationofcharcoalpowderpropellingmethodforth6、edeterminationofratgastricemptyingandintestinalpropulsive;@Theelectrolyteanalyzerforthedeterminationofserumelectrolytelevels;④opticalmicroscopeobservationofthestomachintesfinaltissuemorphologicalchanges;⑤Theenzyme-linkedimmunosorbentassayofjejunalandcolonicmucosaof7、AQP3inofAQP4content.ComparativeStudyofbhizhfi,f6lingandFfiLingtB越ZhfiT五ngtreatingspleendeficiencydiarrhea,andtoexploreitsmechanismofaction.Results:①Theopticalmicroscopeobservationshowedthatthetreatmentgroupshavedifferentlevelsofdamagetoimprove:thejejunumandcolonpar8、tsweresignificantlyimprovedinffilinggroup;therectumwassignificantlyimprovedinbhizhfigroupandFfiLingBfiiZhfi下吞ng.②therateofgastricresidualwerealld
