  • Patent number: 10208097
    Abstract: The present invention relates to a saxatilin derivative having an increased half life and a use thereof. The saxatilin derivative of the present invention has thrombolytic ability similar to that of saxatilin, which is the mother protein, a remarkably increased protein half life, and efficiently dissolves, for long period of time, blood clots already formed in blood vessels of an animal model with a FeCl3-induced carotid by using the same. Therefore, a composition containing, as an active ingredient, the saxatilin derivative of the present invention does not cause reocclusion after penetration and effectively opens to microvessels, and is thus very useful for treating angiostenosis or occlusive diseases (for example, cerebrovascular diseases, cardiovascular diseases, arteriosclerotic vascular diseases, coronary artery diseases, and peripheral vascular diseases).

  • Patent number: 9982021
    Abstract: The present invention relates to: a composition for dissolving thrombi comprising a peptide comprising the Arg-Gly-Asp motif; a pharmaceutical composition for treating stenotic or occlusive vascular diseases which comprises the same; and a thrombus dissolving method and a method for treating stenotic or occlusive vascular diseases, comprising the step of administering the same. The compositions and methods of the present invention have the advantage that they effectively break down already formed thrombi by adopting the principle of targeting integrin within the thrombus such as platelet surface GPIIb-IIIa, which is not the same as the existing principle of plasminogen activation. Also, the compositions and methods of the present invention have a nerve-protecting function as they effectively open as far as the microvasculature, without the occurrence of restenosis after penetration.

  • Publication number: 20050207752
    Abstract: Provided is a physical quantity measuring method using a Brillouin optical fiber sensor. An optical fiber is set on a structure and a pair of pulse lights having different pulse widths is selected. The pulse lights are sequentially transmitted through the optical fiber to obtain back scattering lights and Brillouin gain spectra. The Brillouin gain spectra are compared to each other to calculate a normalized spectrum and a Brillouin frequency is acquired based on the normalized spectrum. The Brillouin frequency is multiplied by a conversion factor of a corresponding physical quantity of the structure to obtain the physical quantity. Accordingly, a portion of the optical fiber from which a sensing signal can be acquired is shortened to improve spatial resolution.
