  • Patent number: 5416078
    Abstract: The invention relates to fluid resuscitation of the human or animal body by administration of deferoxamine (DFO) and a water-soluble biopolymer.The DFO and the biopolymer are preferably bonded together.The biopolymer may be a polysaccharide or a protein.The DFO and the biopolymer are preferably formulated as an aqueous solution suitable for oral administration.The fluid resuscitation may be effected for ameliorating systemic oxidant injury occurring during ischemia and subsequent reperfusion.The fluid resuscitation may be indicated in treatment of burn injury, lung injury caused by inhalation of hot and/or toxic substances, such as smoke derived from combustion, hemorrhagic shock and other types of trauma.

  • Patent number: 5217998
    Abstract: A method for scavenging free iron or aluminum in fluids such as physiological fluids involves a provision in such fluids of a soluble polymer substrate having chelator immobilized thereon. According to the invention preferred such compounds comprise polysaccharides or proteins having a deferoxamine moiety thereon. Such a compound can be used for the treatment of iron overload, as well as to inhibit cell damage from oxidation/reduction reactions. In one embodiment, cell damage during reperfusion is inhibited, through provision of the chelating moiety at the site of reperfusion.
