目的:探讨葛根素(Puerarin,Pue)对大鼠肝脏缺血再灌注损伤(HepaticIschemiaReperfusion,HIR)的保护作用,进而探讨其作用机制。方法:清洁级雄性SD大鼠80只,随机分4组,每组又按再灌注时间分为4个时相。建立HIR模型,检测血清 ALT、MDA、SOD水平;检测TNF-α、IL-6表达以及电镜下对大鼠肝脏形态的观察。结果:血清中ALT、MDA含量按顺序为IR> IP>Pue>Sham,而SOD的含量依次为Sham>Pue>IP>IR,结果差异均具有统计学意义;肝组织TNF-α、IL-6的阳性细胞表达率按顺序为IR>IP>Pue>Sham,差异具有统计学意义(P<0.05)。电镜下观察肝脏形态,损伤程度依次为IR>IP>Pue>Sham。结论:IP和Pue都对大鼠HIR有一定的保护作用,且葛根素的效果要更好。 Objective To study the effect of Puerarin on liver Ischemia Reperfusion in Rats Method Health adult male SD 80 ratswere randomly divided into four groups, and each group was divided into four groups according to reperfusion time Hepatic ischemia reperfusion model was made, the levels of serum ALT, MDA, SOD, the expression of TNF - α and IL -6 was dertermined; in electron microscopethe morphology of rat liver was observed.Results The levels of serum ALT,MDA:IR > IP > Pue > Sham ; and the SOD level:Sham > Pue> IP > IR.Liver tissue's TNF - α and IL -6 expression rates of positive cells was IR > IP > Pue > Sham,The difference was statistically significant( P IP > Pue >Sham.Conclusion Preconditioning and Puerarin can reduce liver ischemia reperfusion injury of the liver, and the effect of Puerarin is better.
