Abstract
A study has been made into the effects of blood pressure on the spinal cord blood flow. Under conditions of normoxia and normocarbia a well-functioning autoregulation was present between 150-60 mmHg. Below 60 mmHg the flow decreased with reductions in pressure. In individual dogs, autoregulation was sometimes present to 40 mmHg. Under conditions of hypoxia or hypercarbia, autoregulation was absent or severely impaired. The results are discussed in relation to the cerebral circulation and to some aspects of experimental cord disease.
摘要
一项关于血压对脊髓血流影响的研究已经展开。在常氧和常碳酸血症条件下，血压在150 - 60 mmHg之间时存在良好的自动调节功能。血压低于60 mmHg时，血流随压力降低而减少。在个别犬只中，自动调节功能有时可维持到40 mmHg。在低氧或高碳酸血症条件下，自动调节功能缺失或严重受损。结合脑循环及实验性脊髓疾病的某些方面对这些结果进行了讨论。
