【摘要】 目的观察阿托伐他汀 (Ato)及细胞因子阻断剂AG4 90对 90 %肝切除术后大鼠剩余肝细胞功能和存活率的作用。方法在标准 90 %肝切除后 ,大鼠随机分为 3组 ,对照组不用任何药物 ;Ato组术前 1d至术后 3d胃管内注入阿托伐他汀 (2 0mg/kg) ;AG4 90组术中至术后 36h内每隔 12h腹腔内注射AG4 90 (1mg/kg) ,观察术后生存及肝再生情况。 结果对照组大鼠 2 4h内 10 0 %死亡。阿托伐他汀和AG4 90均明显地延长了 90 %肝切除术后大鼠的生存时间 (2 5 6h和 30 6hvs.10 7h ,P <0 0 5 )。结论细胞因子阻断剂和阿托伐他汀能显著延长极限肝切除术后大鼠的生存时间 ,为重大肝手术患者术后保护肝功能提供了一定的理论依据。更多还原

【Abstract】 Objective To observe the effects of atorvastatin and cytokine signaling inhibitor AG490 on the residual liver function and the survival time of 90% hepatectomy rats. Methods Rats were divided randomly into three groups after surgery: control group without treatment; Ato group administrated with atorvastatin (20 mg·kg -1·d -1) through NG tube one day before and three days after the surgery and AG490 group, intraperitoneally given AG490 (1 mg·kg -1·12h -1) beginning intraoperatively for 4 times. The health status and liver regeneration were observed and recorded. Results All rats in control group died within 24 hours. Both atorvastatin and AG490 significantly prolonged the survival time of rats after surgery (25.6 h & 30.6 h vs. 10.7 h,P<0.05). ConclusionsCytokine signaling inhibitor and atorvastatin can significantly prolong the survival time of rats following extensive liver resection.更多还原
