Abstract: Purification of physiological liquids of organism is performed by passing a physiological liquid with toxicants removed from a patient through a material which has a size a shape, and a structure selected so as to remove toxic compounds in the molecular range of 300 to 30000 Dalton from the physiological liquid and which is composed of a porous hydrophobic divinylbenzene copolymer which initially has surface exposed vinyl groups in which thereafter the vinyl groups are chemically modified so as to form different surface exposed functional groups with a greater hydrophilicity and greater biocompatibility than those of the vinyl groups.

Abstract: A method of producing a material for purification of physiological liquids of organism has the steps of providing a polymer which has a size, a shape, and a structure selected so as to remove toxic compounds from the physiological liquids, chemically modifying a surface of the polymer so as to provide hydrophilicity and biocompatibility, and performing the modification in a medium with a content of organic substance which is efficient for preventing endotoxins contamination of the polymer.

Abstract: A method of purification of physiological liquids of organism has the step of passing a physiological liquid through a material which has a size, a shape, and a structure selected so as to remove toxic compounds from the physiological liquid and is composed of a partially chloromethylated porous highly crosslinked styrene or divinylbenzene copolymerwhich initially have surface exposed chloromethyl groups in which thereafter chlorine is replaced with an element which forms different surface exposed functional groups with a greater hydrophilicity and greater biocompatibility than that of the chloromethyl group.

Abstract: For purification of physiological liquids of organism has the step of passing a physiological liquid is passed through a material which has a size, a shape, and a structure selected so as to remove toxic compounds from the physiological liquid and is produced from a partially chloromethylated porous highly crosslinked styrene or divinylbenzene copolymer which initially have surface exposed chloromethyl groups and in which thereafter chlorine is replaced with an element which forms different surface exposed functional groups with a greater hydrophilicity and greater biocompatibility than that of the chloromethyl group.

Abstract: A method for producing a material for purification of physiological fluids of organism by chemical modification of surface exposed vinyl groups of porous hydrophobic divinylbenzene copolymer to form different surface exposed functional groups which are hydrophilous and biocompatible, without effecting a porous structure and hydrophobic interior of the initial divinylbenzene copolymer.

Abstract: A method of removing beta-2 microglobulin from blood has the steps of removing blood from a patient, passing the blood through a material with a size and a structure selected so as to remove beta-2 microglobulin from the blood, and re-entering the blood from which the beta-2 microglobulin is removed into the patient.

Abstract: A sorbent for removing toxicants from blood or plasma includes a plurality of beads composed of hyper-crosslinked polystyrene-type resin and having a surface which is modified so as to prevent adsorption of large proteins and platelets and to minimize activation of blood complement system without affecting noticeably accessibility of an inner adsorption space of the beads for small and middle-sized toxicant molecules.

Abstract: An artificial kidney system comprises an artificial kidney forming container having an inlet blood port connectable with a patient's artery and an outlet blood port connectable with a patient's vein so that blood from the patient's artery can flow through the inlet port into the container, then through an inner space of the container and then through the outlet blood port into the patient's vein, the inner space of the container being filled with an adsorbent for removing harmful and toxic compounds from a stream of blood flowing in the inner space from the inlet blood port to the outlet blood port, the container being provided with a separate chamber formed inside the inner space and limited by a semi-permeable polymeric ultrafiltration-type membrane which allows water and dissolved small molecules to be transported from blood into the chamber, and suction element connectable with the separate chamber so that the water and the dissolved small molecules are transported from blood into the separate chamber and
