研究了22℃下兔迷走神经运动纤维的快速顺行轴浆转运。C在一小段神经上施加压力屏障。屏障的特征是最大压力和最大压力两侧的梯度。测试范围为最大压力16 ~ 45mmhg，压力梯度为神经长度30 ~ 140mmhg /mm。在测试范围内，最大压力对运输抑制至关重要；压力梯度的影响不大。至少有一部分的快速顺行轴浆运输发生在可折叠的小管结构中。
Fast anterograde axoplasmic transport was studied in the motor fibers of rabbit vagus nerve in vitro at 22.degree. C with a pressure barrier applied to a small section of the nerve. The barrier was characterized by the maximal pressure and the gradients on each side of the maximum. The range tested was 16-45 mmHg maximal pressure and 30-140 mmHg/mm length of nerve for the pressure gradients. In the ranges tested the maximal pressure was of major importance for transport inhibition; the pressure gradient was of little significance. At least 1 part of fast anterograde axoplasmic transport occurs within collapsible canalicular structures.
