title: [Expression of Nogo-A and Nogo receptor in neonatal rats visual system during development].
abstract: OBJECTIVE
  To study the expression of Nogo-A and Nogo receptor (NgR) in the development of neonatal rats retinal and visual cortex and their effects on the development of central nervous system (CNS).
  
  
  METHODS
  Immunohistochemical staining method was used to detect the expression of Nogo-A and NgR in neonatal rats retinal and visual cortex at 1, 3, 7, 14, 28, 56 days after birth. One-way Anova was used to analyze the results of Western blot analysis of Nogo-A and NgR in neonatal rats visual cortex.
  
  
  RESULTS
  Nogo-A and NgR was found to express in neonatal rats retinal and visual cortex at the developing stage. In 1, 3, 7, 14, 28, 56 days, the IDV ratio of Nogo-A was 0.852 ± 0.026, 0.917 ± 0.024, 0.810 ± 0.028, 0.417 ± 0.053, 0.258 ± 0.029, 0.298 ± 0.054 respectively and the IDV ratio of NgR was 0.070 ± 0.014, 0.185 ± 0.035, 0.678 ± 0.046, 0.705 ± 0.021, 1.210 ± 0.057, 1.140 ± 0.0420 respectively by Western blot analysis. The expression of Nogo-A was decreased (F = 376.56, P = 0.000) and the expression of NgR was increased (F = 888.26, P = 0.000) during postnatal development.
  
  
  CONCLUSIONS
  Nogo-A and NgR is closely related to the CNS growth and development.
