1、黄芩苷对急、慢性肝损伤模型鼠的保护作用刘晓君,杨洁芳(重庆市第九人民医院,重庆400700)中图分类号R285;R575文献标志码A文章编号i001.0408(2014)15—1374—03DOI10.6039~.issn.i001—0408.2014.15.i0摘要目的:研究黄芩苷对急、慢性肝损伤模型鼠的保护作用。方法:腹腔注射10%CC1橄榄油溶液(0.2ml/100g)以复制小鼠急性肝损伤模型。5O只KM小鼠随机均分为正常对照(等容生理盐水)组、模型(等容生理盐水)组与黄芩苷高、中、低剂量(1.00、0.5O、O.25g/
2、kg)组。灌胃给药,每天1次,连续6d,末次给药12h后复制模型。另外,腹腔注射硫代乙酰胺(TAA,200mg/kg),每周2次,连续12周以复制大鼠慢性肝损伤模型。5O只SD大鼠随机均分为正常对照(等容生理盐水)组、模型(等容生理盐水)组与黄芩苷高、中、低剂量(0.8、O.4、0.2g/kg)组。复制模型同时灌胃给药,每天1次连续12周。测定鼠血清与肝匀浆中丙氨酸氨基转移酶(ALT)活性,并对鼠肝组织病理学进行评级。结果:与正常对照组比较,模型组鼠血清ALT活性增强,肝组织匀浆ALT活性减弱,差异有统计学意义(P3、鼠肝组织病理程度严重。与模型组比较,黄芩苷高、中、低剂量组鼠血清ALT活性减弱,肝组织匀浆ALT活性增强,差异有统计学意义(P<0.01或P<0.05);鼠肝组织病理程度有一定改善。结论:黄芩苷对急、慢性肝损伤模型鼠具有一定保护作用,其机制与调节ALT水平、改善肝组织病理程度有关。关键词肝损伤;丙氨酸氨基转移酶;病理学;大鼠;小鼠ProtectiveEfectofBaicalinonAcuteandChronicLiverInjuryModelRatsandMiceLIUXiaoojun,YANGJie—fang(Chongqi4、ngNinthPeople’sHospital,Chongqing400700,China)ABSTRACTOBJECTIVE:Tostudyprotectiveeffectonacuteandchroniclivermjurymodelratsandmice.METHODS:Theacuteliverinjurymodelofmicewasinducedbyintraperitonealinjectionof10%Carbontetrachlorideoliveoilsolution(0.2ml/100g).50KMmicew5、ererandomlydividedintonormalcontrolgroup(constantvolumeofnormalsaline),modelgroup(constantvol—umeofnormalsaline),baicalinhigh-dose,medium-doseandlow—dosegroups(1.00,O.50,0.25g/kg).Theyweregivenrelevantmedicinessubcutaneously,onceaday,forcontinuous6days;12hoursafterla6、stadministration,modelmicewereinduced.Thechronicliverinjurymodelofratwasinducedbyintrapefitonealinjectionofthioacetamide(TAA,200mg/kg),twiceaweek,forcontinuous12weeks.50ratswererandomlydividedintonormalcontrolgroup【constantvolumeofnormalsaline).modelgroup(constantvol7、umeofnormalsaline),baicalinhigh-dose,medium—doseandlow—dosegroups(0.8,0.4,0.2g/kg).Theyweregivenrelevantmedicinesintragastrically,onceaday,forconsecutive12weeks.TheactivityofALTinserumandliverhomogenateweredetermined;Thepathologyscaleoflivertissuewasevaluated.RESULTS8、:Comparedwithnormalcontrolgroup,theactivityofALTinserumincreasedinmodelgroup,butthatofliverhomogenatedecreased;therewasstatisticals
