An introduction of laser flow meters for a continuous measurements of a tissue blood flow has opened new avenues for an accurate assessment blood flow in peripheral nerves. The aim of our study was: 1) to carry out a functional verification of anatomical sources of a sciatic nerve blood supply in the rat; 2) develop a measurement technique to facilitate standardisation of results; 3) to determine the role of nerve fibres tonic activity in the maintenance of a resting blood flow in the sciatic nerve. Based on results of the present study the following conclusions have been drawn out: 1) in order to obtain a real values of the blood flow through the sciatic nerve it is necessary to remove its muscular fascia; 2) an uninjured epineurium plays a crucial role in maintaining the resting blood flow; 3) major blood supply of sciatic nerve comes from inferior gluteal and popliteal arteries; 4) the tonic neural activity plays a role in the maintenance of the resting sciatic nerve blood flow in anaesthetised rats.
用于连续测量组织血流的激光流量计的引入，为准确评估周围神经的血流开辟了新途径。我们研究的目的是：1）对大鼠坐骨神经血液供应的解剖学来源进行功能验证；2）开发一种测量技术以促进结果的标准化；3）确定神经纤维紧张性活动在维持坐骨神经静息血流中的作用。基于本研究结果得出以下结论：1）为了获得通过坐骨神经的真实血流值，有必要去除其肌筋膜；2）完整的神经外膜在维持静息血流中起关键作用；3）坐骨神经的主要血液供应来自臀下动脉和腘动脉；4）紧张性神经活动在维持麻醉大鼠坐骨神经静息血流中起作用。
