  • Patent number: 5817312
    Abstract: The direct, concentrated local delivery of antibodies, and pooled human immunoglobulins in particular, to tissue surfaces (e.g., wounds, burns, etc.), and biomaterial implant surfaces significantly decreases the rate of infection at those sites and enhances healing. The immunoglobulins serve to opsonize circulating infectants for phagocytosis and killing, prior to microbial adhesion and biofilm formation, and neutralize bacterial toxins. The treatment methodology results in reduced inflammation, reduced complement and tissue damage, and reduced rejection of biomaterials and transplants.

  • Patent number: 5770234
    Abstract: A non-specific host defense cell augmentation technique for enhanced microorganism killing utilizes any phagocytosable particle to prime macrophages for enhanced oxidative response and bacterial killing. The phagocytosable particles should be administered at the time of exposure to contagion, or one day prior to or up to 6-12 hours after exposure. Administration can be performed by any suitable means which will bring the particles quickly into contact with the blood stream where they will encounter phagocytes and cause priming of the patient's macrophages. The augmentation technique provides for non-specific cellular immunity from a wide range of contagion.

  • Patent number: 5591441
    Abstract: A non-specific host immune cell augmentation composition for enhanced microorganism killing utilizes any phagocytosable, biocompatible particle to prime macrophages for enhanced oxidative response and bacterial killing. Patients can have the benefits of primed macrophages in one to four days, and experiments have demonstrated over a 100-fold increase in oxidative potential within this time period. The oxidative response and killing potential is non-immunospecific, meaning not one organism, not a vaccine, and broadly applicable simultaneously to bacteria and viruses as well as tumor cells. The effects have been demonstrated to have a seven day duration to have a seven day duration indicating non-tissue toxic residual effects and potential for repeated use at monthly intervals.

  • Patent number: 5505945
    Abstract: Compositions containing a high concentration of the full repertoire of immunoglobulins, including IgA, IgM and IgG, are used to combat infections from microorganisms and viruses at a wound, surgical, or burn site, or normal tissue times of risk of infection. The compositions can contain elevated antibody titers for several specific pathogens including S. aureus, Coagulase Negative Staphylococci Enterococci, S. epidermidis, P. aeruginosa, E. coli, and Enterobacter spp., etc. The compositions are applied directly to a wound or burn site as an ointment, creme, fluid, spray, or the like, prior to viral or bacterial attachment or biofilm formation such that adhesion of the pathogens is inhibited and the pathogens closest to the wound or burn site will be pre-opsonized for phagocytic killing prior to toxin release.
