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.

A method for assessing the prognosis of a patient undergoing therapy for cancer by measuring the granulocyte/lymphocyte ratio of the patient's blood and comparing the ratio to a normal range of 1.6.+-.0.6. The prognosis is considered improved when the G/L value is within the range as compared to when it is greater than the same.

Resin composition suitable for use in medical devices

A resin sheet having a porous layered structure useful as an electrode separator for electric cells, said sheet comprising (a) an olefin resin, (b) a finely divided inorganic substance, and (c) at least one substance selected from the group consisting of (i) a water-swellable thermoplastic resin, (ii) a water-insoluble or difficultly water-soluble hydrophilic nonionic surface active agent, and (iii) a water-insoluble difficultly water-soluble hydrophilic anionic surface active agent, said sheet including fine pores arranged throughout its cross section in a plurality of layers, at least some of them forming open cells. The above sheet is prepared by a process comprising fabricating a mixture containing the above components (a), (b) and (c) into a sheet, and stretching the sheet in at least one direction.
