1、·基礎(chǔ)醫(yī)學(xué)·2013年5月第3卷第9期番茄紅素對刀豆蛋白誘導(dǎo)的小鼠肝纖維化的影響袁永種趙凱江蘇省金壇市人民醫(yī)院消化科,江蘇金壇213200【摘要】目的觀察對刀豆蛋白誘導(dǎo)鼠肝損干預(yù)前后的肝纖維化半定量計分(SSS計分)變化和小鼠肝臟大體形態(tài)及病理學(xué)HE染色結(jié)果變化,探討番茄紅素對刀豆蛋白誘導(dǎo)的小鼠肝纖維化的影響。方法昆明小鼠64只,隨機(jī)分為4組:正常組8只、模型組8只、預(yù)防組8只及治療組40只,治療組按治療時間(1—5周)分為5組,每組8只。刀豆蛋白A(conA)經(jīng)腹腔注射8周建立肝纖維化小鼠模型。預(yù)防組在建模的同時、治療組在建模成功后予番茄紅素20m
2、g灌胃給藥,每天1次,觀察肝纖維化半定量計分變化水平,同時觀察小鼠肝臟大體形態(tài)及病理學(xué)HE染色結(jié)果,并與正常組及模型組比較。結(jié)果預(yù)防組及治療組肝病理學(xué)染色結(jié)果好轉(zhuǎn)明顯。結(jié)論番茄紅素能有效對抗實(shí)驗(yàn)小鼠肝纖維化,抑制了肝纖維化的發(fā)展速度,并可能逆轉(zhuǎn)肝纖維化。【關(guān)鍵詞】番茄紅素;肝纖維化半定量計分;小鼠肝臟病理學(xué);HE染色【中圖分類號1R285.5【文獻(xiàn)標(biāo)識碼】A[文章編號】2095—0616(2013)09-30—03EffectoflycopeneonmurineHverfibrosisinducedbyConAYUANYongchongZHAOKai
