Measurements of oxygen tension in the canine lumbar intervertebral disc, by the use of a polarographic oxygen electrode, were performed. The oxygen tension in the arterial blood was changed by regulating the oxygen concentration in the inspired air. The alterations in oxygen tension in the nucleus pulposus, as a function of distance to the vertebral endplate were determined. The response times registered in the disc matrix were relatively short (within five min.), which implies an efficient solute transport from the vertebral blood pool underneath the hyaline cartilage into the avascular intervertebral disc.
利用极谱氧电极对犬腰椎间盘的氧张力进行了测量。通过调节吸入空气中的氧浓度来改变动脉血中的氧张力。确定了髓核中氧张力随距椎体终板距离的变化。椎间盘基质中记录的响应时间相对较短（在五分钟内），这意味着溶质能有效地从透明软骨下方的椎体血池转运至无血管的椎间盘。
