WE CLAIM:
1. A material for removing an activated leukocyte-activated platelet complex,
the material being a water-insoluble carrier to the surface of which carrier a
compound(s) having a charged functional group(s) is(are) bound,
wherein an extending length ratio of said surface is 4 to 7.
2. The material for removing, according to claim 1, wherein a center line mean roughness of said surface is 2 to 10 um.
3. The material for removing, according to claim 1 or 2, wherein the absolute value of charge amount of the functional group(s) is 0.3 to 3.0 mmol per 1 g dry weight of said water-insoluble carrier.
4. The material for removing, according to any one of claims 1 to 3, wherein said charged functional group is an amino group.
5. The material for removing, according to any one of claims 1 to 4, wherein said water-insoluble carrier is in the form of fibers, and the fiber has a fiber diameter of 1 to 100 um.
6. The material for removing, according to any one of claims 1 to 5, wherein said water-insoluble carrier comprises one or more polymers selected from the group consisting of polystyrene, polysulfone, and polyethersulfone.
7. The material for removing, according to any one of claims 1 to 6, wherein the material adsorbs and removes an activated leukocyte, IL-6, IL-8, or HMGB-1.
8. A column for blood purification, the column comprising the material for removing, according to any one of claims 1 to 7.
9. A column for blood purification for treating a respiratory disease, the column comprising the material for removing, according to any one of claims 1 to 7.
