Of them, 2 rats received lateral cord transsection at caudal injection region. 其中2只大鼠在注射区尾侧加作脊髓外侧索横断。
Rats in the 3 groups were made into spinal transsection injured models. Hind limb palsy was established. Rats in the early transplantation group and postpone transplantation group were selected to remove NSCs of rats at day 3 and week 3 after injury. 3组大鼠均制作脊髓横断损伤模型,造成大鼠下肢瘫痪,早期移植组、延期移植组大鼠分别在伤后3d及3周移植胎鼠脑组织神经干细胞。
The process of the pathological changes of DAI were: misalignment of the intra axonal structures, axonal swelling and transsection. 轴突损伤的过程为:轴突内结构的紊乱,轴突肿胀及断裂。
