  • Publication number: 20220338788
    Abstract: Apparatus for the non-invasive in-vivo determination of changes in tissue, e.g. the myelination, of the optic nerve (ON) in a biological subject, said apparatus comprising: a laser source for generating an excitation laser beam; an optical system including a fundus camera operatively associated with the laser source for use in obtaining a fundus image for illuminating the optic nerve (ON) of a subject with the excitation laser beam; a detector (13) operatively associated with the optical system and configured to detect a Raman spectrum from the optic nerve (ON) and/or surrounding cerebral spinal fluid; and a processor provided with a computer program for comparing the detected Raman spectrum to at least one reference spectrum. The reference spectrum may correspond to the myelination of the optic nerve in a normal, healthy subject, for determining the changes in the myelination of the optic nerve of the subject based on the detecting and comparing steps from the Raman spectrum.

  • Patent number: 5958411
    Abstract: The present invention relates to methods for preventing, suppressing or treating a CNS pathology characterized by a deleterious accumulation of extracellular matrix in a tissue by contacting the tissue with an agent that inhibits the extracellular matrix producing activity of TGF-.beta.. The methods can be used to prevent, suppress or treat scar formation in the CNS. Agents that are useful in the present methods include neutralizing anti-TGF-.beta. antibodies, Arg-Gly-Asp-containing peptides, decorin and its functional equivalents such as biglycan, and TGF-.beta. antagonists. The present invention further provides methods for preventing, suppressing or treating a CNS pathology characterized by the insufficient accumulation of extracellular matrix. Agents that enhance the production of extracellular matrix, such as TGF-.beta., can be used in such methods.
