  • Patent number: 10639320
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating liver fibrosis or liver cirrhosis, and more specifically, to a pharmaceutical composition for preventing or treating liver fibrosis or liver cirrhosis comprising a gold-containing agent. The pharmaceutical composition of the present invention, by comprising the gold-containing agent as an active ingredient, not only promotes M2-type transformation of macrophages but also inhibits the activation of stellate cells due to the increase of TREM-2 expression, and is thus expected to be effectively used as a pharmaceutical composition, a food composition, etc., for preventing, treating, or ameliorating liver fibrosis or liver cirrhosis. Additionally, gold-containing agents, such as auranofin, sodium aurothiomalate, and aurothioglucose, have long been used for the treatment of a different disease (rheumatoid arthritis), and thus they have an advantage in that they are less likely to cause adverse effects.

  • Publication number: 20190008864
    Abstract: The present invention relates to a pharmaceutical composition containing a G protein coupled receptor 119 (GPR119) ligand as an effective ingredient for preventing or treating non-alcoholic steatohepatitis. More particularly, it was confirmed that the GPR119 ligand, which has been developed as only an anti-diabetic drug, exhibits superior effects on the treatment of non-alcoholic fatty liver and the signal pathways in hepatocytes therefor differ from the signal pathways in the small intestine and the pancreas exhibiting anti-diabetic effects, whereby the GPR119 ligand can be useful to treat non-alcoholic steatohepatitis.

  • Patent number: 9895370
    Abstract: Provided is a pharmaceutical composition for preventing or treating liver fibrosis, comprising a GPR119 ligand as an active ingredient. The composition comprising the GPR119 ligand as an active ingredient significantly inhibits the expression of collagen I, transforming growth factor ? (TGF?) and ?-smooth muscle actin (?-SMA), thereby inhibiting HSC activation, and also significantly inhibits HSC proliferation. Therefore, the composition may be effectively applied in improvement, prevention, inhibition or treatment of liver fibrosis.

  • Patent number: 9833145
    Abstract: Provided are a method for simultaneously detecting fluorescence and Raman signals for multiple fluorescence and Raman signal targets, and a medical imaging device for simultaneously detecting multiple targets using the method. The method includes: injecting at least one marker particle comprising Raman markers and receptors into the body of an animal, which can be a human; irradiating a laser beam onto the body of the animal; and detecting the optical signals emitted by the marker particle after the irradiation of the laser beam separately as fluorescence signals and Raman signals. The simultaneous detection of multiple targets may be performed even without scanning optical signals emitted by the marker particle individually with different optical fibers. As an examination may be performed by injecting surface-enhanced Raman marker particles, weak Raman signals may be augmented so as to obtain a more accurate diagnosis result in real time.
