  • Patent number: 6913805
    Abstract: The present invention provides an apparatus and method for controlled release of a fumigant into a wooden structure to prevent decay of that structure. According to the present invention, a fumigant in an ampule or container is inserted into the wooden structure. The ampule or container is made of a polymeric material that does not react with the fumigant, but having walls which are permeable to the fumigant such that, when inserted into the wooden structure, the rate of release of the fumigant through the walls of the ampule is slow enough to continuously treat and arrest decay of the wooden structure, particularly decay caused by fungi, over extended periods of time (i.e., 1, 5, 7, 10, 15, 20 or 30 years). The rate of release of the fumigant can be controlled by the type of fumigant, the shape of the container, the specific polymer used to make the container, and by the thickness of the container wall.

  • Publication number: 20030138397
    Abstract: The present invention relates to a method of inhibiting a toxin in an animal, such as a human, by administering to the animal a therapeutically effective amount of a polymer having a plurality of pendant acid functional groups which are directly attached to the polymer backbone or attached to the polymer backbone by a spacer group. The spacer group can have a length in the range from 0 to about 20 atoms. The toxin is, typically, an exotoxin secreted by a pathogenic microorganism, such as a bacterium.

  • Patent number: 6596291
    Abstract: Compositions and methods are disclosed for treating a hair-bearing surface of a warm-blooded animal, including humans, dogs and cats infested with an ectoparasitic insect, such as lice and/or fleas. Compositions and methods are also disclosed for preventing the infestation or re-infestation of an ectoparasitic insect, such as lice and/or fleas on a hair-bearing surface of a warm-blooded animal, including humans, dogs and cats. The compositions include either a water-soluble polyalkylene glycol or a water-soluble polyalkylene oxide mixed with a polymer or copolymer comprising polyalkylene oxide having carboxylic acid-containing residues. Methods of the invention include topical application to a hair-bearing surface of an effective amount of a composition of this invention, and maintaining the same on the surface for a sufficient period of time to treat the surface.

  • Patent number: RE38913
    Abstract: A BIOCOMPATIBLE HYDROGEL, is provided for use in the treatment of humans for cosmetic and functional defects (e.g. in mammas, vocal cords, penis, etc. as endoprostheses), in the provision of intratissue storage sites the prolonged-action medicinal preparations, in various applications as electroconductive immersion media, and in the life-long tamponing of caverns. It contains an acrylamide-based polymer produced in the presence of an initiator of radical polymerization in apyrogenic water as the dispersion medium. An increase in elasticity, shape retention capability, and stability of bulky implants, as well as corresponding therapeutic and cosmetic efficacy, mainly in the endoprosthetic applications is achieved due to the hydrogel containing cross-linked polyacrylamide produced by using a biocompatible cross-linking agent, such as methylene-bis-acrylamide, and preferably a mixture of ammonium persulfate and tetramethylethylenediamine as the initiator of polymerzation.
