  • Patent number: 6261577
    Abstract: Non-staining topical iodine disinfecting compositions having the ability to inactivate pathogens associated with skin infections or diseases. based upon the presence of molecular iodine in a concentration above at least 15 ppm. Any other iodine species selected from the group consisting of complexed iodine and triiodide may be present with the total of such other iodine species limited to a concentration of less than about 700 ppm so that any visible stain resulting from the application of this composition on the skin will dissipate without leaving any visible skin coloration.
    Type: Grant

  • Patent number: 5885592
    Abstract: The invention is a method of administering therapeutic iodine for treating a disorder in a mammal. The invention comprises a step of feeding said mammal an effective amount of an oxidant for an iodine species and an iodine reductant which will cause oxidation-reduction reactions upon contact with the gastric juices present in the stomach of the mammal. This is done such that molecular iodine is generated in vivo at a ratio of molecular iodine to total iodine of above at least about 0.65. The invention also discloses a non-aqueous pharmaceutically acceptable carrier with said oxidant and reductant having the ability to cause oxidation-reduction reactions upon contact with the gastric juices present in the stomach of said mammal and in an amount sufficient to generate molecular iodine, in vivo, at a ratio of molecular iodine to total iodine of above at least about 0.65.
    Type: Grant

    Inventors: Yongjun Duan, John Hickey, Rick Panicucci, Jack Kessler
  • Patent number: 5419902
    Abstract: This invention relates to a method for inactivating pathogens using the peroxidase enzyme. The peroxidase enzyme is reacted with hydrogen peroxide or a source of hydrogen peroxide and an iodide anion to generate reaction products which are separated from the peroxidase enzyme and then used to inactivate pathogenic organisms.
    Type: Grant

    Assignee: GENE-TRAK Systems
    Inventors: May K. Li, Jack Kessler, David T. Bach
  • Patent number: 4983523
    Abstract: A new method for releasing sample nucleic acids from cells, bacteria and viruses comprises non-invasively sonicating the sample contained within a sample container brought into physical contact with the vibrating element of a sonicator tuned to resonate at a frequency of 40 KHz or greater.

  • Patent number: 4473550
    Abstract: Bactericidal compositions and methods include the use of a peroxide and a peroxidase in a defined area such as the mouth to rapidly and efficiently kill bacteria. Donor molecules are transformed into bactericidal free radicals which carry out the desired action. The compositions and methods are particularly effective in alleviating gingival disease and periodontal disease.
