A blood treatment material adsorbs and removes blood components such as activated leukocytes and inflammatory cytokines with a high efficiency. The blood treatment material includes a water-insoluble material in the form of fibers or particles, wherein the difference between the maximum value (RaA) and the minimum value (RaB) of the arithmetic average roughness (Ra) of the surface of the water-insoluble material, as calculated using a laser microscope, is from 0.30 to 1.50 μm.

Blood treatment material

An object of the present invention is to provide a carrier for adsorbing organic matter, which achieves both of adsorption ability for organic matter and suppression of pressure increase. The present invention provides a carrier for adsorbing organic matter, comprising a sea-island type solid composite fiber, wherein the pore volume is 0.05 to 0.5 cm/g and the fiber diameter is 25 to 60 &#x3bc;m.

Carrier for adsorbing organic matter

An object of the present invention is to provide a material for blood purification having the capability to remove cytokines and activated leukocyte-activated platelet complexes. The present invention provides a material for blood purification, the material containing a water-insoluble material in which a ligand having an amide group(s) and an amino group(s) is bound to a substrate, wherein the content of the amide group(s) is 3.0 to 7.0 mmol per 1 g dry weight of the water-insoluble material; and wherein the content of the amino group(s) is 1.0 to 7.0 mmol per 1 g dry weight of the water-insoluble material.
