摘要
目的:研究犬肝移植模型中,肝动脉缺血对血清中TGF-β1值的影响及其意义。方法:24只杂交犬被随机分为正常对照组、肝动脉门静脉同时开放组和肝动脉缺血组,每组8只。肝动脉门静脉同时开放组在制模后,同时开放肝动脉和门静脉,并在肝动脉和门静脉开放后0h、2h、6h、12h和24h分别抽血留样;肝动脉缺血组在制模后,先开放门静脉,2h后再开放肝动脉,在肝动脉开放后0h、2h、6h、12h和24h分别抽血留样;正常对照组开腹后仅游离肝脏并解剖相应的血管,在此之后0h、2h、6h、12h和24h分别抽血留样。ELISA法测定血清中的TGF-β1值。结果:正常对照组随着手术时间的延长,其血清中TGF-β1值无显著变化;肝动脉门静脉同时开放组和肝动脉缺血组在制模后,随着时间的延长,其血清中TGF-β1值逐渐升高,肝动脉门静脉同时开放组各时点之间无显著性差异(P>0.05),肝动脉缺血组各时点值之间有显著性差异(P<0.05);TGF-β1值在3组各时点相比较差异显著(P<0.05)。结论:在犬肝移植模型中,肝动脉缺血可引起血清中TGF-β1值显著升高。
Objective:To study the influence and the significant of hepatic artery ischemia on the value of serum TGF-β1 in the liver transplantation model of dog.Methods:24 dogs were divided into normal control group,open hepatic artery and portal vein group(HPOS) and hepatic artery ischemia group(HAI) randomly,each group having 8 dogs.After the models were induced,the hepatic artery and portal vein were opened simultaneously and the blood samples were drawn at 0h,2h,6h,12h and 24h in the HPOS group;in the hepatic art...
