Immunoglobulin adsorbent and adsorption apparatus
First Claim
1. An apparatus for adsorbing an immunoglobulin in a body fluid comprisinga vessel having an inlet and an outlet for passing body fluid therethrough,an adsorbent for an immunogloblin charged in said vessel, said adsorbent comprising a hydroxyl-containing water-insoluble carrier to which a diamine compound having the general formula:
-
space="preserve" listing-type="equation">NH.sub.2 (CH.sub.2).sub.n NH.sub.2wherein n is an integer having a value of 3 to 9 is attached through a silane coupling agent or a derivative thereof, a heterocyclic compound being attached to the amine through a difunctional reagent, andmeans for preventing the adsorbent from flowing out of said vessel.

Abstract
For the treatment of various diseases including autoimmune diseases such as myathenia gravis, articular rhematism, lupus erythematosus, etc., immunity-related diseases such as glumerulonephritis, bronchial asthma, polyneuritis, etc., organ transplantation such as transplanted kidney rejection, AOB incompatibility bone marrow transplantation, etc., tumor, hypertension, and hepatic insufficiency, immunoglobulin adsorbents comprising a hydroxyl-containing water-insoluble carrier to which a diamine compound having the general formula:
NH.sub.2 (CH.sub.2).sub.n NH.sub.2
wherein n is an integer having a value of 3 to 9 is attached through a silane coupling agent or a derivative thereof, to which diamine a heterocyclic compound is attached through a difunctional reagent, are useful as they can selectively and efficiently adsorb specific proteins such as immunoglobulins and immune complexes which are pathogenic substances in the diseases, exhibit minimized non-specific adsorption, and are safe and easy to sterilize.
