Abstract: PCT No. PCT/JP84/00431 Sec. 371 Date May 7, 1986 Sec. 102(e) Date May 7, 1986 PCT Filed Sep. 10, 1084 PCT Pub. No. WO86/01744 PCT Pub. Date Mar. 27, 1986.This invention relates to a method of ion-exchange and/or adsorption, and to a method of producing pure water. More specifically, this invention relates to a method of ion-exchanging and/or adsorbing an unnecessary product or a useful product in a liquid to be treated. Concretely, this invention relates to a method of ion-exchange and/or adsorption and to a method of producing superpure water by first treating the liquid with an ion-exchange resin, and then treating the liquid with an ion-exchange fiber.

Abstract: An object of this invention is to provide an adsorbent for immunosuppressive substance, which adsorbent can highly efficiently and selectively adsorb an excessive immunosuppressive substance directly from the body fluid, can carry out extracorporeal perfusion safely and can be utilized in treatment of cancer. Such an excessive immunosuppressive substance may be involved in growth of cancer cells. An adsorbent for immunosuppressive substance of the invention includes a water-insoluble carrier and a hydrophilic amino group immobilized to the water-insoluble carrier. An extracorporeal perfusion column of the invention contains the adsorbent of the invention. A method for treating cancer of the invention carries out extracorporeal perfusion using the extracorporeal perfusion column of the invention.

Abstract: An immunosuppressive substance adsorbent capable of selectively adsorbing excess immunosuppressive substances considered to be associated with the multiplication of carcinoma cells directly from humor at high efficiency and capable of safe extracorporeal circulation, which immunosuppressive substanc e adsorbent is useful for the treatment of cancer. In particular, an immunosuppressive substance adsorbent characterized by comprising a water insoluble carrier and, fixed thereto, hydrophilic amino groups. Further, the re is provided an extracorporeal circulation column characterized by being pack ed with the above adsorbent. Still further, there is provided a method of treating cancer characterized in that extracorporeal circulation is performe d by the use of the above extracorporeal circulation column.

Abstract: Disclosed is a fiber obtained by at least partially fibrillating or splitting a composite fiber having an islands-in-sea construction comprising a plurality of island components which are separated from and parallel to each other in the axial direction of the composite fiber and are surrounded by a sea component, wherein the sea component is made of an ion exchange resin and the island components are made of a reinforcing polymer which is not an ion exchanger. Also disclosed is a sheet composed of such a fiber. The fibrous resin is particularly useful in tobacco filters which may selectively reduce ionic, polar and mutagenic components as well as tar and nicotine in tobacco smoke.

Abstract: The present invention is a filter for tobacco smoke containing a fibrous ion exchange resin, and also a fibrous ion exchange resin useful for making such a filter in which at least a part of the fiber is fibrillated or split. Using the filter of the invention makes it possible to remove very efficiently from tobacco smoke substances harmful to the human body, such as ionic substances, polar substances, carcinogenic substances, mutagenic substances, as well as nicotine and tar.
