  • Patent number: 11946051
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating hypertrophic scars. The present inventors have found that the inhibition of expression of TXNDC5, PRRC1, S100A11, Galectin 1, Filamin A, eIF-5A, Annexin A2, and FABP5 can be a new target for improving and treating hypertrophic scars. In the present invention, TXNDC5-, PRRC1-, S100A11-, Galectin 1-, Filamin A-, eIF-5A-, Annexin A2-, and FABP5-specific siRNAs were constructed to determine the probability of treating the hypertrophic scars. As a result, the knockdown of the protein or a gene encoding the protein induces apoptosis in the hypertrophic scars and reduces collagen expression, which can be very useful in treating wounds.

  • Patent number: 11781992
    Abstract: Disclosed is a test strip for detecting microalbumin in urine, and more particularly a test strip for detecting microalbumin in urine that contains a synthetic albumin indicator, a buffer solution, a surfactant and a polymer (sensitizer) and thus exhibits high sensitivity. The albumin detection test strip has accuracy sufficient to enable clear observation of color change from colorless to blue through the albumin indicator, and improves the detection limit (increases sensitivity) to thereby enable detection of microalbuminuria at a concentration of 20 mg/L or less. The albumin test detection strip contains a surfactant and a polymer in addition to a synthetic albumin indicator, thereby incorporating separate first and second processes into a single process and having effects of reducing costs, improving processing convenience, and increasing solubility and miscibility.
