ABSTRACT
Objective To observe the effect of different conserve time in ultra deep cryopreservation (-196 ℃)on physiological characteristics of allograft nerve transplantation .Methods A total of 80 female Wistar rats were divide into three groups by random principlederived group which 20 rats were sacrificed to get both sides of femoral nerves ;control groups which each group had 10 rats include group A for fresh autologous nerve transplantation ,group B for fresh allograft nerve transplantation ;experiment groups which each group had 10 rats including groups C ,D ,E ,F that transplanted after femoral nerves conserve in the -196 ℃ for 3 ,6 ,9 , 12 weeks respectively ,and the results of exterior appearance ,light microscope ,electron microscope were observed and electrophysi-ological test was conducted after transplantation .Results After 9 weeks transplantationthe physiological characteristics of group B was most affected ,followed by group C ,D ,E ,F ,group A was with minimal impact ;the result of electrophysiological test showed that groups A&B ,A&E ,A&F had significant difference(P<0 .05) .Conclusion The physiological characteristics of allograft nerve transplantation relate to the freezing time .
