Haemoperfusion and oxygen saturation were studied by tissue reflection spectra on the dural sac of dogs, Experimentally, decompression laminectomy and external pressure on the dural sac were carried out. Haemoperfusion and oxygen saturation were investigated in the open state, and after an external pressure was applied. After the application of external pressure, paraplegia occurred. The tissue Spectrum Analyser 'TS-200' (Sumitomo Electric Industries Co. Ltd, Japan) was used for the measurement of haemoperfusion and oxygen saturation. With this apparatus, an optical fibre probe is applied to irradiate tissue with white light, and the absorption spectrum of the reflected light from tissue is analysed. It has been confirmed that oxygen saturation was not changed in either state, however, haemoperfusion was decreased when external pressure was applied.
通过组织反射光谱对犬硬脊膜囊的血液灌注和血氧饱和度进行了研究。实验中，进行了减压性椎板切除术和对硬脊膜囊施加外部压力的操作。研究了开放状态下以及施加外部压力后的血液灌注和血氧饱和度。施加外部压力后，出现了截瘫。使用组织光谱分析仪“TS - 200”（日本住友电气工业株式会社）测量血液灌注和血氧饱和度。利用该仪器，将光纤探头用于用白光照射组织，并分析从组织反射的光的吸收光谱。已证实，两种状态下血氧饱和度均未改变，然而，施加外部压力时血液灌注降低。
