【摘要】 自体静脉套接或神经原位移植修复大鼠面伸经法隙缺损．术后３个月应用ＨＲＰ逆行追踪法研究了周围器官与中枢核团联系的变化．结果表明３ｍｍ静脉管与３ｍｍ神经移植体一样引导再生轴突通过修复区．与神经移植体相比，３ ｍｍ静脉管能促使面神经再生轴突定向再生．躯体定位关系恢复胞体增大是其支配更大范围靶肌的代偿表现．更多还原

【Abstract】 Three months after repairing of the defected rat facial nerves with either a venous or a nerve graft,HRP retrograde-tracing technique was used to examine the relationship between the peripheral targets and central nucleus. The results showed that the venous graft guides the regenerated axons across the 3 mm defect region as well as the nerve graft and promote orientational regeneration.更多还原
