Nogo(N-18) EXPRESSION IN NORMAL RETINA AND AFTER THE OPTIC NERVE INJURY IN HAMSTERS / 解剖学报

Objective To study the distribution of Nogo-A in the retina and the changes after the optic nerve(ON) injury in hamsters. Methods In this experiment,ON was crushed at 2?mm behind of the eyeball.After 3?d,5?d and 7?d post-axotomy,the Nogo antiserum immunoreactive staining on section of the retina was performed. Results Nogo was expressed at every layer of the retina with the strongest expression on 3?d post-axotomy.The numbers of Nogo-A positive RGCs decrease as the survived time increased.Conclusion Nogo-A in the retina is not unique secretion from the neuroglia.The change in the distribution and level of expressed of Nogo-A in the retina is correlated with time advancement after injured of ON.
