2、对慢性醋酸型胃溃疡的影响。④对幽门结扎型胃溃疡的影响,同时检测胃液量、总酸、游离酸和胃蛋白酶活力。结果①银耳多糖主要通过局部作用抑制应激型溃疡的形成,末次给药1h后做诱导溃疡试验,试验组溃疡划级为1.85±083,对照组为4.29±101,两组之间有非常显著差异(P<0001),末次给药12h后做诱导溃疡试验,试验组溃疡划级为332±0.97.对照组为4.23±081,两组之间无显著差异(P>005)。②对消炎痛型溃疡有抑制作用,与对照组比较两组之间有显著差异(P3、制作用,与对照组比较,两组之间有非常显著差异(P<0O1o④对幽门结扎型溃疡有显著抑制作用,与对照组比较,两组之间有非常显著差异(P<0.001),银耳多糖的制酸效应和抑制胃蛋白酶活力,分别与对照组比较两组之间有非常显著差异(P<0.001)。结论银耳多糖对大鼠应激型溃疡,慢性醋酸型溃疡,幽门结扎型溃疡和消炎痛型溃疡均有抑制作用,以前三项作用强。其作用机制以制酸为主.并有保护胃黏膜和抑制胃蛋白酶活力的作用。【关键词】银耳多糖;胃溃疡模型;前列腺素【Abstract】0bjectiveToinvestigatetheapp4、roachandmechanismofantiulcerefectoftremellapolysaccharidewithdiferenttestmethodsanddiferentulcermodels.Methods①Twomethodsofmedicineadministeringwereusedtoinvestigatetheapproachofefectoftremellapolysaccharideonthestressulcer.②111eeriectonandindomethacinulcerandthe5、relationshiptoprostaglan曲1E,(PGE2)wereinvestigated.③Theefectonthechronicaceticacidgastriculcerwasinvestigated.(Theefectonthepyloricligationgastriculcerandthegastricjuicevolume,totalacidoutput,freeacidandpepsinactivitywereinvestigated,Results①Tetremel-lapolysaccha6、rideinhibitedtheformationofthestressulcermainlywithlocalefect.Theulcerinducedtestwasperformedonehourafterthemedicinewasadministeredforthelasttime.Thecriterionwas1,85±0.83inthetestgroupand4.29+1.01inthecontrolgroupTherewassignificantdiferencebetweenthetwogroups(P<7、0.001).111eulcerinducedtestwasperformed12hoursafterthemedicinewasadministeredforthelasttime.Thecriterionwas3,32±0.97inthetestgroupand4,23±0.81inthecontrolgroup.Therewasnosignificantdiferencebetweenthetwogroups(P>0.05).②111etremellapolysaccharidecouldinhibittheind8、omethacinulcerandtherewassignificantdiferencewiththecontrolgroup(P<0,05).Thetremellapolysaccharidehadnoefectonprostaglandin,⑨Thetremellapolysaccharidecouldsign
