Apoptosis of lumbar spinal cord neurons in cauda equina syndrome rats / 药物分析学报

Objective To explore the law of apoptosis of lumbar spinal cord neurons in cauda equina syndrome (CES). Methods Cauda equina of rats was compressed by a piece of silica gel stick. From day 1 to day 28, the lumbar spinal cord specimens were harvested and assessed by Nissl's staining and TUNEL staining. Results Compression of cauda equina caused lesion and apoptosis of neurons in lumbar spinal cord, and the extent of apoptosis reached the peak on 7th day after compression. Conclusion Apoptosis of neurons in lumbar spinal cord might be one of the reasons why patients with CES get poor prognosis.
