  • Patent number: 8178516
    Abstract: This invention defines novel compositions that can be used for clinical treatment of a class of chronic inflammatory diseases. Increased generation of carbonyl substances, namely aldehydes and ketones, occurs at sites of chronic inflammation and is common to the etiologies of all of the clinical disorders addressed herein. Such carbonyl substances are cytotoxic and additionally serve to perpetuate and disseminate the inflammatory process. This invention defines use of compositions, the orally administered required primary agents of which are primary amine derivatives of benzoic acid capable of covalently reacting with the carbonyl substances. p-Aminobenzoic acid (or PABA) is an example of the required primary agent of the present invention. PABA has a small molecular weight, is water-soluble, has a primary amine group which reacts with carbonyl-containing substances and is tolerated by the body in relatively high dosages for extended periods.

    Abstract: The present invention discloses a polymeric polyamine which can be produced by polymerizing polyoxyalkylene-amine and a linker. The linker can be anhydride, carboxylic acid, epoxy, isocyanate or poly(styrene-co-maleic anhydride) copolymers (SMA). The present invention also discloses a method for stabilizing the Ag nanoparticles with polymeric polyamine. The polymeric polyamine serving as a stabilizer or dispersant is mixed with a water solution of silver salt and then a reducer is provided to reduce the silver ions and form an organic or a water solution of Ag nanoparticles. Water or solvent of this solution can be further removed through a heating, freezing or decompression process, and thus solid content of the solution can be increased. The concentrated solution also can be diluted to obtain a stable dispersion without aggregation.
