Abstract

Blood flow was measured in the bone marrow and trabecular bone of the dog using 133Xe and hydrogen clearance technique. Estimated from hydrogen wash-out curves, flow in the marrow of the femoral diaphysis was 0.207 ml.min(-1).g(-1), in the marrow of the humerus 0.123ml.min(-1).g(-1) and in the trabecular bone of femoral metaphysis 0.173ml.min(-1).g(-1). Haemorrhagic hypotension and fracture reduced the medullary flow. After haemorrhage an exponential relationship was found between blood pressure and effective bone marrow and muscle blood flow. The correlation between systemic arterial and intramedullary pressures was found to be exponential and between intramedullary pressure and flow linear.

摘要

采用¹³³氙和氢清除技术测量了犬骨髓和松质骨的血流量。根据氢洗脱曲线估计，股骨干骨髓血流量为0.207ml·min⁻¹·g⁻¹，肱骨髓血流量为0.123ml·min⁻¹·g⁻¹，股骨干骺端松质骨血流量为0.173ml·min⁻¹·g⁻¹。失血性低血压和骨折会降低髓内血流量。出血后，血压与有效骨髓和肌肉血流量之间呈指数关系。发现全身动脉压与髓内压之间呈指数相关，而髓内压与血流量之间呈线性相关。
