ENGLISH AbstractS OF ORIGINAL ARTICLES Prothrombin Complex Concentrate Prepared by Modified GelAdsorption Method
【摘要】 采用DEAE-SephadexA50和DEAE-SepharoseCL-6B凝胶从人血浆中吸附制备经S/D病毒灭活处理后的PCC制品,DEAE洗脱液经S/D处理(0.3%磷酸三丁脂和1%Twen80,6~8h,24℃)后,使所加入具有感染剂量(>106)的标志病毒VSV、Sindbis、HIV均被有效灭活;PCC制品中Ⅱ、Ⅶ、Ⅸ、Ⅹ因子的比活性(U/mg)分别为0.799±0.349、0.343±0.252、0.747±0.348、0.580±0.199(n=7),均比传统PCC提高1.5~2.5倍(其中FⅨ∶C的比活性提高有显著性,t=3.105,P<0.01),同时也优于国内同类制品(t=2.360,P<0.05),对其杂蛋白(AT-Ⅲ、Fn、PKA、Plg、ⅧR∶Ag抗A、抗B凝集素)的分析也反映出PCC纯度有所提高。SDS-PAGE、IE、CIE电泳图谱及HPLC层析图谱证实上述结果,PCC中TNBP残留量≤10μg/ml,Tween80残留量≤100μg/ml,均在安全范围内。
【Abstract】 OF ORIGINAL ARTICLES Prothrombin Complex Concentrate Prepared by Modified GelAdsorption Method$$$$ Yu Rong,et al (Institute of Blood Transfusion,Chinese Academy of Medical Sciences & Peking Union Medical College) Abstract The prothrombin complex concentrate,viruses in which were inactivatedly treated by solvent/detergent,was adsorbatedly prepared from human plasma,using DEAE sephadex A50 and DEAE sepharose CL 6B gels.The DEAE eluate was incubated with SD mixture 0.3% tri (n buty 1)phosphate(TNBP) and 1% Tween 80 for 6~8h at 24℃,so the added indicant viruses in the eluate,such as VSV,Sindbis and HIV with infective dose>10 6,were effectively inactivated.The specific activity of factors Ⅱ,Ⅶ,Ⅸ,Ⅹ in the prothrombin complex concentrate products( n =7) was 0.799±0.349,0.346±0.252,0.747±0.348,0.580±0.199U/mg,respectively.Obviously,their specific activity was higher than that of traditional prothrombin complex concentrates by 1.5~2.5 times (among them,the specific activity of FⅨ∶C was improved significantly, t=3.105,P <0.01),and in the meantime,its quality was better than other prothrombin complex concentrate products prepared domestically ( t=2.360,P <0.05).Analysis of impure proteins such as AT Ⅲ,FN,PKA,Plg,anti A and anti B hemagglutinins showed that its purity was improved.The SDS PAGE,IE,CIE and HPLC also demonstrated the mentioned above results.The residual level of TNBP and Tween 80 in the prothrombin complex concentrate was <10 μg/ml and 100μg/ml,respectively,and fell within the safe range.
