Objective to evaluate the effect of neuron growth factors (NGF) and neuron growth inhibitors (NGI) on the growth of chick embryonic dorsal root ganglion (DRG) axon.
目的研究神经生长因子(NGF)和神经生长抑制因子(NGI)对鸡胚背根神经节(drg)轴突生长的影响。
The concentration of serum CGRP in spinal anterior motor-neuron and dorsal root ganglion was measured and X ray photograph taken at 1,2 and 4 weeks after injury.
于伤后1周、2周及4周对骨折处拍摄x线片，放射免疫法测定脊髓前角运动神经元及背根神经节中CGRP含量；
Results: 14 days later, positive FB marked cells were found in the spinal cord segment and the dorsal root ganglion; the number FB labelled neuron and the fluorescence were increased soon afterwards.
结果：14天时神经元胞体开始出现FB，随后荧光逐渐加强和阳性标记细胞逐渐增多；
