中文摘要：

目的:观察β1,4-GalTImRNA在坐骨神经损伤后相应节段脊髓和背根神经节中的表达变化。方法:采用real-timePCR方法,分析β1,4-GalTImRNA在大鼠坐骨神经损伤后相应脊髓和背根神经节中的表达变化。运用原位杂交检测β1,4-GalTI在脊髓和背根神经节中的定位情况。结果:Real-timePCR显示,与正常脊髓和背根神经节相比,β1,4-GalTI在坐骨神经损伤后发生表达变化。原位杂交结果显示β1,4-GalTI在正常脊髓中的表达较弱,主要表达于脊髓灰质中,而损伤后在灰质和白质中均可见有大量的阳性信号。β1,4-GalTI在背根神经节中则主要定位于神经元。结论:本实验发现β1,4-GalTI在正常脊髓和背根神经节中有表达,并在坐骨神经损伤后发生表达变化。提示β1,4-GalTI在周围神经损伤后再生和退变过程中可能发挥一定的作用。

英文摘要：

Objective: To observe the expressive changes of β1,4-GalT I mRNA in corresponding spinal cord and dorsal root ganglion after sciatic nerve injury. Methods: Real-time PCR was used to detect the expressive changes of β1,4-GalT I mRNA in corresponding spinal cord and dorsal root ganglion after sciatic nerve injury. The localization of β1,4-GalT I mRNA in corresponding spinal cord and dorsal root ganglion was explored by using in situ hybridization. Results: Real-time PCR re- vealed that, compared with the norm...
