Abstract
We have now examined an EVAL-CD membrane with UFR and cut-off point lower than those of the C membrane, for protein permeability and clinical effect. The protein permeability of the CD membrane stands between those of the C membrane and standard EVAL membrane, slightly near to the former side. In regard to the clinical effect of the CD membrane, improvement in itching, irritation and bone pain similar to the C membrane was observed but i t was slightly moderate.
