Abstract
Granulocytes can be removed from blood by bringing the blood into contact with a carrier having higher affinity to granulocytes than to lymphocytes. the carrier may preferably be a substance having a contact angle in a range of 55.degree.-95.degree. to water, e.g., polystyrene, cellulose acetate, nylon, polytrifluoroethylene or polyethylene terephthalate. A granulocyte removing apparatus is also disclosed. It comprises a granulocyte-adsorbing portion enclosing therein a carrier having higher affinity to granulocytes than to lymphocytes, a blood inflow port for causing blood to flow into the adsorbing portion, and a blood outflow port for allowing the blood, which has flowed in the adsorbing portion, to flow out of the adsorbing portion.
