METHOD OF WITHDRAWING GALL-STONES FROM PATENT'S BODY (VARIANTS) AND ALKYLATED CROSS-LINKED POLYMER FOR CARRYING IN THROUGH Russian patent published in 2000 - IPC

FIELD: chemistry of polymers. SUBSTANCE: described is method of withdrawing gall-stones from patient's body which comprises using therapeutically effective amount of ion-exchange resin. Ion-exchange resin is reaction product comprising one or more cross-linked polymers containing recurring structural unit selected from group consisting of units of formula 1,2,3 and salt and copolymer based thereof, wherein n is integer and each radical R is independently H, or C₁-C₈ alkyl group, and at least one alkylating agent; in this case some nitrogen atoms in structural polymer units do not interact with alkylating agent and less than 10 mole % of nitrogen atoms in structural units interacting with alkylating agent form quaternary ammonium compounds. EFFECT: simplified method of removing cholic acid salts from patient's body. 55 cl, 28 ex
