2、方(50ml/kg)灌胃后再進(jìn)行染毒。正常組僅給予生理鹽水。觀察比較各組小鼠的生存率、肝功能水平、組織病理學(xué)變化以及相關(guān)炎癥分子的變化情況。結(jié)果:給予小鼠ConA能誘導(dǎo)明顯的肝損傷,表現(xiàn)為血漿ALT、AST水平顯著升高,大量肝細(xì)胞發(fā)生凋亡壞死。清腸利肝方干預(yù)組小鼠的ALlT、AsT水平低于染毒組,差異有顯著性意義(P<0.05),病理結(jié)果顯示肝損傷亦得到明顯減輕;此外,干預(yù)組各項(xiàng)炎癥分子如細(xì)胞外組蛋白、IL-6,MCP一1,TNF-o【等水平顯著低于染毒組,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。結(jié)論:清腸利肝方對(duì)ConA所致的小鼠急性肝損傷有顯著防護(hù)作用,其機(jī)制可能與減少細(xì)胞外組蛋白和相關(guān)
