  1. aUltrafiltration rate was measured with bovine blood (hematocrit, 30 ± 3%; total protein, 6.0 ± 0.5 g/dl; blood flow rate, 200 ± 4 mL/min; transmembrane pressure, 13.3 ± 1.3 kPa; temp., 37 ± 1 °C
  2. bClearance was measured with aqueous solution. Blood flow rate, 200 ± 4 mL/min; dialyzate flow rate, 500 ± 10 mL/min, filtration rate, 10 ± 2 mL/min; temp., 37 ± 1 °C
  3. cNegative charge on the membranes was determined from the evaluation of the triiodide complex. It was created by the reaction of iodine and iodide ions after dried hollow fiber membrane immersed in a solution of 5% potassium iodide in methanol for 24 h
