  • DIAGNOSIS OF ACUTE ENTEROCOLITIS BY DETERMINATION OF INTESTINAL FATTY ACID-BINDING PROTEIN IN THE BLOOD
    Publication number: 20090311729
    Abstract: The present invention provides a quick and convenient determination method and a determination reagent for acute enterocolitis, which can determine acute enterocolitis quantitatively and objectively. The I-FABP in collected blood is detected. Preferably, the blood is human blood and I-FABP is human I-FABP, and blood I-FABP is detected by an immunological method. As an immunochemical method, any of an enzyme immunochemical method, a latex agglutination method and an immunochromatography method can be used, and an enzyme immunochemical method is preferably used. More preferably, a sandwich-type enzyme immunoassay is used.

  • Compositions and Methods for Generation of Infectious Hepatitis C Virus in Immortalized Human Hepatocytes
    Publication number: 20090148832
    Abstract: The present invention provides a cell line capable producing infectious hepatitis C virus 1a (HCV 1a) particles in culture. Disclosed are compositions and methods for an HCV 1a (clone H77) transfected immortal human hepatocyte (IHH) capable of generating infectious HCV 1a virus particles in culture. Also disclosed are methods of using the cell line, or HCV 1a virus particles derived from said cell line, to screen for potential therapeutic agents which interfere with HCV 1a virus propagation to treat hepatic disease.
