【 要旨 】 生体適合性は最終的には臨床で評価されるべきであるが,臨床では,さまざまな因子が影響を与えているので,結果の解釈が難しい.一方,材料開発の分野においては,臨床での使用条件と異なる条件下で評価されることが多い.したがって,できるだけ臨床に近い条件での比較が可能なin vitroでの生体適合性の評価も,新たな情報を得るうえで,非常に有用である.それぞれから得られた結果を相補的に利用することで,さらに生体適合性に優れたダイアライザや透析膜の開発につながると考える.

[ Summary ] The biocompatibility of dialysis membranes should ultimately be evaluated in clinical settings. However, it is difficult to interpret clinical data because of the involvement and mutual influence of a variety of factors. Meanwhile, in the basic research field of material sciences, materials for biological applications are mostly evaluated under non-clinical conditions. To acquire new information, it is useful, therefore, to evaluate the biocompatibility of materials, to the extent possible, under conditions similar to clinical ones by using in vitro experiments. These evaluations will enable clinical data to be integrated into material evaluation data, thereby enabling the incorporation of the combined data into the design of membrane materials.
