title: A New Poly(Methyl Methacrylate) Membrane Dialyzer, NF, with Adsorptive and Antithrombotic Properties.
abstract: Poly(methyl methacrylate) (PMMA) membranes adsorb several kinds of proteins and can remove high-molecular-weight proteins, including uremic toxins, which are not removed efficiently by hemodialysis or hemodiafiltration. However, the antithrombogenicity of PMMA membranes is insufficient due to their adsorptive properties.
  
  
  
  Coagulation during hemodialysis occurs because proteins that are adsorbed to the PMMA membrane undergo structural changes and are recognized by platelets, which are then activated by adhesion to the membrane surface. In developing a new PMMA membrane dialyzer, NF, we intended to inhibit platelet adhesion to the membrane surface by suppressing the structural change in the proteins adsorbed on the membrane. In addition, we give examples of clinical trials of the NF in Japan and describe its advantages. Key Message: PMMA membrane dialyzers have been used for 40 years. The PMMA dialyzer NF can suppress the adhesion of platelets to the membrane while maintaining protein adsorption.
