    Abstract: PROBLEM TO BE SOLVED: To provide an adsorptive material capable of selectively adsorbing LDL oxide with substantially no loss of the effective components in body fluid. SOLUTION: The adsorptive material prepared by imparting a dialkylaminoalkyldextran to a supporting body selectively adsorbs the LDL oxide and therefore the material is capable of removing the LDL oxide with substantially no loss of the effective components in the body fluid.

    Abstract: PROBLEM TO BE SOLVED: To improve a blood remaining characteristic by passing a model blood which exhibits the behavior similar to the behavior of the human total blood of a specific temperature in a relation between a viscosity and a shear rate in a specific amount in such a manner that the residual amount of the model blood at the time of washing with a specified amount of a phosphoric acid buffer solution of a specific pH and specific formulation attains a specific value or below. SOLUTION: The model blood which exhibits the behavior similar to the behavior of the human total blood of 37 deg.C in the relation between the viscosity and the shear rate is introduced into the hollow fiber type blood purifying device at a flow rate of 1.28 times the volume of the flow passage of this device. The hollow fiber membranes are then washed by passing the phosphoric acid buffer solution of pH 7.5 at 125 ml/m2 per unit inside surface area of the hollow fiber membranes and at a flow rate of 100 ml/min. The human total blood is hematocrit(ht) 40%.total protein(TP) 8. The phosphoric acid buffer solution is 5.33 mmol disodium hydrogenphoshate dodecahydrate, 1.34 mmol potassium dihydrogenphoshate and 154 mmol sodium chloride. The remaining of the blood after washing is confined to

    Abstract: PROBLEM TO BE SOLVED: To provide a polysulfone membrane with suppressed adsorption of proteins as a membrane for separation or concentration of antigens, enzymes or the like or for hemocatharsis by dialysis of blood or filtration of blood. SOLUTION: The membrane comprises a polysulfone resin containing a hydrophilic polymer or a polymer having a hydrophilic segment. In the IR absorption spectra of the membrane measured at 100 points with a 20×20 μm angle of view, the number of measuring points satisfying an inequality of (Aco)/(Acc)≤0.15 is ≤5, wherein Aco is the intensity of the absorption peak indicating C=O near 1660 cm -1 and Acc is the intensity of the absorption peak indicating the benzene ring C=C in the polysulfone near 1580 cm -1 . The average μof the ratio (Aco)/(Acc) is ≥0.1 and COPYRIGHT: (C)2003,JPO
