Study of biocompatibility with various blood purification membranes
To study the bio compatibility of blood purification membrane, the blood passing test was conducted by using several minimodules of different membranes at the same time on a single subject. The subjects were three healthy male and the membranes used were PE, PVA, EVAL (D) and EVAL (4A). The membrane...

Abstract | To study the bio compatibility of blood purification membrane, the blood passing test was conducted by using several minimodules of different membranes at the same time on a single subject. The subjects were three healthy male and the membranes used were PE, PVA, EVAL (D) and EVAL (4A). The membrane area of each module was 0.01m2. Blood was withdrawn from the median cubital vein through PVC tubings and let to five modules (one module was blank) where the blood flowed at a rate of 10ml/min. Ten minutes later, the blood was sampled to investigate the influence of each membrane material on the complement system by measuring the activation of complements (C3a, C4a). The complements were most strongly activated by PVA, followed by EVALs (D and 4A), PE, and “blank”. There was no significant difference in the effect between EVAL (D) and EVAL (4A).
血液浄化膜の生体適合性の検討の一方法として同一被験者で同時に素材、および膜構造の異なるミニモジュールを用いて通血試験を行い、いくつかの項目について興味ある知見が得られた。すなわち、3名の男性被験者にそれぞれPE, PVA, EVAL (spec D. 4A)のミニモジュール(膜面積0.01m2)を並列に連結し、肘正中皮静脈から採血し、PVC製チューブで5等分(1個所はブランク)して10ml/minで通血し、10分後に採取して血漿の補体活性化(C3a, C4a)を測定し、膜素材の補体への影響を検討した。また、使用後のそれぞれの中空糸膜における付着蛋白量、有形成分の付着状態などについて、GPC, N分析, SEMなどの手法によって解析した。膜素材による補体の活性化の順位は, PVA>EVAL(D, 4A)>PE>ブランクであり、EVALのD、4Aの構造物性の差の影響は認められなかった。 |
