ABSTRACT
Objective To investigate the effects of transplantation of sciatic nerve(SN) and injection of 8-(4-Chlorophenylthio)-cAMP(CPT-cAMP) into the viteous on axotomized retinal ganglion cells(RGCs) in adult hamsters. Methods Twenty adult golden hamsters were ramdomly divided into 4 groups.Optic nerve(ON) was transected and a segment of autologous sciatic nerve(attached graft,AG) was removed and sutured to the proximal stump of ON in regenerating control group(AG group).The animals in experimental groups were further treated with CPT-cAMP injection and/or implantation of a short of segment sciatic nerve(SN) intravitrously.Fluorescent retrograde labeling method and quantitative anatomical techniques were used to measure the number of RGCs. Results 1.In control (AG) retinas,the mean number of regenerating RGCs was 1*!428?284/retina.2.In AG+SN group,the mean number of regenerating RGCs was 2*!220?415/retina.3.In AG+cAMP group,the mean number of regenerating RGCs was 2*!175?364/retina.4.The mean number of regenerating RGCs in AG+cAMP+SN group were 4*!255?820/retina.AG+SN,AG+cAMP groups were significantly different from AG group(P
