骨循环血量对于维持骨内环境稳定具有重要作用。骨循环血量主要受神经、体液和代谢因素控制。本文研究骨循环对血管活性物质的反应及骨血管床的受体种类,以达到有效地控制骨血流量的目的。选取数只骨成熟犬,解剖出胫骨营养动脉,接体外循环泵的输出端,输入端接一侧肱动脉,调整泵的频率使骨血管床保持持续灌注状态。从输出端测得骨循环灌注压(BPP),从另一侧
Circulating blood volume plays an important role in maintaining the stability of the bone environment. Bone circulation blood volume is mainly controlled by nerves, body fluids and metabolic factors. This article studies the response of bone circulation to vasoactive substances and the types of receptors in the bone vascular bed in order to achieve an effective control of bone blood flow. Select a few mature dog bone, tibial nutrition artery dissected out, then the output of extracorporeal circulation pump, the input side of the brachial artery termination, adjust the frequency of the pump so that the bone vascular bed sustained perfusion state. Percutaneous perfusion pressure (BPP) was measured from the output from the other side
