  • Publication number: 20110270411
    Abstract: The present invention discloses an artificial nerve graft prepared by electrostatic spinning, the preparing method and a special apparatus used therefor. Said artificial nerve graft is in the shape of a tube composed of nano-fiber that is prepared by electrostatic spinning of a polymer. The materials used in the present invention are bio-degradable materials and of desirable biocompatibility with human body. The product of the present invention is free of exogenous toxic substances or substances having side effects. Furthermore, the tube wall is of a 3-dimensional structure having micropores contained therein thereby providing a path for supplying nutritions required for the growth of nerve cells. Another advantage of the present invention is that necessary induction and space are provided for the growth of the nerve cells.

  • Publication number: 20080249639
    Abstract: A medical artificial nerve graft containing silk fibroin used in bridging of nerve damage and its preparation method. The medical artificial nerve graft comprised of vessel or comprised of vessel and fibre scaffold, wherein at least one of the vessel and the fibre scaffold contains component of silk fibroin, and the wall of the vessel has three-dimensional structure provided with numerous microaptures. The preparation method includes the following steps: silk is used to prepare silk fibre; the silk fibroin fibre is used to prepare the vessel or the fibre scaffold containing silk fibroin; and combining the fibre scaffold with the vessel i.e. inlaying the fibre scaffold into the vessel and so on.

  • Publication number: 20060117399
    Abstract: This invention develops the first mouse model for human lymphomas with mutations in the NF-KB2 gene that can be used for the study of the pathogenesis of this subset of lymphomas and for the development and testing of therapeutic and prevention drugs. The mice develop B- and T-cell lymphomas with extensive metastases in the liver, lung and kidneys, and can be used as an animal model for the development and testing of therapeutic/prevention drugs that target this group of human lymphoma patients.

  • Patent number: 6399087
    Abstract: A sterile, stable pharmaceutical formulations of oil-in-water emulsions of Propofol containing no preservative are provided that comprise optimal amounts of egg lecithin and soybean oil, with a suitable pH range to prevent significant growth of microorganisms for at least 24 hours after adventitious, extrinsic contamination. The lower pH in the formulation has shown the most antimicrobial activity. The reduced amount of fat in the formulation also allows chronic sedation over extended periods of time with a reduced chance of fat overload in the blood.
