Heavy Metal Containing Patents (Class 424/604)
  • Patent number: 7842306
    Abstract: This disclosure relates to wound care devices which are capable of one-way, directional flow of fluids and contaminants away from the wound site to the opposite side of the wound care device, which functions as a fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess fluid, and potentially even bacteria, and is carried out without loss of physical integrity of the wound care device itself. In addition to providing a unidirectional fluid transport mechanism, the wound care device may contain a topically applied silver-based antimicrobial finish which provides certain levels of antimicrobial agent to the wound in order to clear infection from the wound site and control bacterial growth in the wound care dressing. Exemplary topical antimicrobial finishes include silver ion-releasing compounds.

  • Publication number: 20100272827
    Abstract: Embodiments provide devices, systems and methods for the transdermal delivery of chelated compounds. One embodiment provides a method for the iontophoretic transdermal delivery of a chelated iron complex for the treatment of anemia. A first patch comprising an active electrode and a chelated iron complex is applied to the skin; a second patch containing an electrode is also applied. An electrical current is then delivered to the skin from the active electrode. The chelated complex is transported across the skin via electromotive force from the current, with the iron being substantially chromogenically unreactive with the skin during transport so that there is little or no tattooing of the skin due to the formation of insoluble oxidative products. The complex is then dissociated by phagocytosis or related process to release the iron where it may be bound by transferrin or ferritin and carried to other sites for storage or metabolic use.

  • Patent number: 7790167
    Abstract: The methods and compositions of the present invention are directed to enhancing an immune response and increasing vaccine efficacy through the simultaneous or sequential targeting of specific immune system components. More particularly, specific immune components, such as macrophages, dendritic cells, B cells and T cells, are individually activated by component-specific immunostimulating agents. One such component-specific immunostimulating agent is an antigen-specific, species-specific monoclonal antibody. The invention is also directed to a method for the in vitro production of the antigen-specific, species-specific monoclonal antibodies which relies upon the in vitro conversion of blood-borne immune cells, such as macrophages and lymphocytes. Vaccine efficacy is enhanced by the administration of compositions containing component-specific immunostimulating agents and other elements, such as antigens or carrier particles, such as colloidal methods, such as gold.

  • Patent number: 7147872
    Abstract: Environmentally friendly processes for prevention of qualitative deterioration and quantitative loss of plant matter and foodstuffs, during all stages of storage and handling, including pre- and post-harvest, pre- and post-planting, distribution and marketing involves the use of H2O2 compositions including Ag and at least one of Cu and Zn ions. The processes can also be used to prevent sprouting and rooting, and to promote fecundity of certain plant matter, and can also be used to eliminate or reduce quantities of harmful organisms and substances from soil, other growth media and substrates, equipment, materials water, workspaces and surfaces.

  • Patent number: 7125570
    Abstract: An antibacterial composition is provided which comprises a base, an antibacterial agent consisting of a silver-supporting inorganic compound and a water-soluble salt of a nitrogen atom-containing 6-membered heterocyclic compound. In the antibacterial composition, the silver component susceptible to discoloration is effectively stabilized by the use of the water-soluble salt of a nitrogen atom-containing 6-membered heterocyclic compound and therefore, the antibacterial composition never or hardly undergoes any discoloration with the lapse of time.

  • Patent number: 7118761
    Abstract: Wound care devices having a topically applied silver-based antimicrobial finish are provided. The finish comprises at least one silver ion-containing compound and at least one binder compound. The finish may be applied to a target substrate, such as a fiber, fabric, film, foam, hydrogel, or hydrocolloid to provide a single layer antimicrobial wound care device. Alternatively, a silver-containing layer may be combined with one or more additional layers of target substrate to provide a composite antimicrobial wound care device. The device may also contain an odor-absorbing component capable of reducing or eliminating odors that are inherently associated with infectious wounds. Also provided is a method for making the wound care device and a composition of matter comprising the silver-based antimicrobial finish.
