自血光量子疗法治疗实验性脊髓损伤

Treatment of Experimental Spinal Cord injury with Autohemotherapy or Light Quanta

目的 探讨自血光量子疗法治疗脊髓损伤的作用机理。方法６０只家兔造成不全性脊髓损伤，分为损伤组和治疗组，进行脊髓血流量、脊髓诱发电位、丙二醇含量、钙组织化学染色和电镜的对比。结果自血光量子疗法能增加脊髓血流量；激活神经细胞的兴奋性和传导性；减轻自由基介导的脂质过氧化；阻滞钙经通道向细胞内流动；保护脊髓组织的超微结构。结论自血光量子疗法可以避免或减轻急性脊髓损伤后仍然存在的进行性，继发性损伤，促进脊髓功能恢复。

Aim To inquire into the mechanism of autohemotherapy of light quanta (ALQ) on spinal cord injury. Methods After being subjected to incomplete spinal cord injury, sixty rabbits were divided into ALQ treating group and non-treating control group, and the changes of spinal cord blood flow, spinal cord evoked potential, content of malondialdehyde, calcium histochemical staining, and elec- tron microscopic structure had been examined. Results ALQ could increase spinal cord blood flow,acti- vate irritability and conductivity of neuron, reduce lipid peroxidation by free radical intervention, retard calcium passing through channel into cell, and protect the ultrastructure of spinal cord. conclusion ALQ could prevent or eliminate progressive and secondary injury after acute spinal cord injury, and promote the recovery of spinal cord function.
