  • Publication number: 20140303256
    Abstract: The present invention relates to a pharmaceutical composition for the prevention and treatment of blood-brain barrier disorder comprising fluoxetine as an active ingredient. More particularly, fluoxetine inhibits the expressions of matrix metalloproteinase(MMP)-2, MMP-9, and MMP-12, which are reported to be related to blood-brain barrier (BBB) disruption and inflammatory reaction after spinal cord injury, specifically inhibits the activations of MMP-2 and MMP-9, inhibits the decomposition of ZO-1, the most representative tight junction protein, so as to maintain tight junction between endothelial cells and to protect blood-brain barrier thereby, inhibits the increase of blood-brain barrier permeability, and inhibits the expressions of chemoattractants of blood cells, such as CXCL-1, CXCL-2, CCL-2, CCL-3 and CCL-4 so as to reduce inflow of blood into spinal cord and recover exercise function which has been deteriorated by spinal cord injury.

  • Publication number: 20050233140
    Abstract: Disclosed is a polytrimethylene terephtalate conjugate fiber having high self-crimpability, which is prepared by conjugate-spinning two types of polytrimethylene terephtalates having different intrinsic viscosities in which a difference between the intrinsic viscosities ranges from 0.05 to 0.15 into a side-by-side fiber. Also, the polytrimethylene terephtalate conjugate fiber prepared by the conjugate-spinning undergoes a false twisting process, leading to development of three-dimensional high self crimpability and sufficient bulky property in the resulting fiber.
