  • Kits and method for detecting human papilloma virus with oligo nucleotide bead array
    Patent number: 8017757
    Abstract: Provided are determining methods of human papillomavirus (HPV) genotypes with a high sensitivity. The method includes performing two-step PCRs on an HPV L1 gene in a sample to be analyzed as a biotin-labeled, single-stranded L1 gene, performing a hybridization reaction on the biotin-labeled, single-stranded L1 gene with a HPV genotype detection probe, reacting the hybridization reaction product with fluorescent substance combined with streptavidine, and measuring a fluorescent substance level to identify the HPV genotype. The detection method has high sensitivity enough to detect an extremely small amount of HPV in the sample. In addition, the high specificity exhibited by the detection method enables accurate diagnosis specific to HPV type.

  • Methods for treating hyperplasia
    Patent number: 6197808
    Abstract: A method for a treatment of hyperplasia caused by papilloma virus, such as Condyloma acuminata, which comprises concomitantly topically and orally administering at least one tea catechin. Tea catechins do not involve the risk of side-effects and may be easily administered by the patients themselves.
