  • Publication number: 20090169527
    Abstract: A therapeutic for use in inducing angiogenesis and vasculogenesis, the therapeutic including angiogenesis and vasculogenesis inducing factors isolated from stem cells in conjunction with a pharmaceutically acceptable cell therapy. A method of amplifying the production of angiogenesis and vasculogenesis inducing factors secreted by exposing stem cells to and co-culturing the stem cells with a compound for increasing the production of angiogenesis and vasculogenesis inducing factors. Angiogenesis and vasculogenesis inducing factors isolated and purified from stem cells for use in a therapy. A process for obtaining the angiogenesis and vasculogenesis inducing factors as set forth above, the process including the steps of isolating and purifying human mesenchymal stem cells from tissue prior to differentiation and then culture expanding the mesenchymal stem cells to produce a tool for neurological and musculoskeletal therapy.

  • Patent number: 7198369
    Abstract: This invention discloses an achromatopsia inspection/correction method, comprising the following steps: displaying a plurality of groups of achromatopsia test charts for the examinee to identify, each group is corresponding to one type of achromatopsia; determining the types of achromatopsia based upon the inspection results; displaying at least one colored color-matching contrast chart, one area of said color-matching chart is in a predetermined color, another area is for the examinee to match colors; taking the color-matching result from the examinee; determining the achromatopsia scales of the examinee by comparing the color-matching results of the examinee with said predetermined three elementary colors; selecting the corresponding achromatopsia correction spectrum curves according to the determined types and scales of achromatopsia. Besides, this invention also discloses an achromatopsia inspection/correction apparatus for realizing this method.

  • Patent number: 5369453
    Abstract: Rectifying method for color blindness and rectifying eyeglasses for color blindness by using a computer to simulate the process of rectifying color blindness, there are produced 32 kinds of spectrums and parameters of rectifying eyeglasses for color blindness, which are then grouped under four types. The rectifying eyeglasses for color blindness change the proportion of stimulus of three kinds of optic cone cells on the retina and alter the color codes of the visional area of cerebral cortex, thus when a color-blind viewer wears the eyeglasses chosen properly, the ability of discrimination between different colored objects is greatly improved.
