Abstract

Pressure was measured in the femoral medullary cavity of rabbits whose femoral muscles were subjected to electrostimulation. After electrostimulation the pressure in the medullary cavity increased fivefold. In groups of experimental animals the number of reticulocytes leaving the bone marrow and the number of reticulocytes in the peripheral blood were determined and it was observed that electrostimulation was followed by a severalfold rise in the amount of reticulocytes in both the bone marrow and the peripheral blood. The authors found that a great role in the egress of reticulocytes from the bone marrow into the circulation is played by regulation of the pressure in medullary cavity effected by changes in blood flow through the bone marrow.

摘要

对股部肌肉接受电刺激的家兔的股骨髓腔压力进行了测量。电刺激后,髓腔内压力增加了五倍。在几组实验动物中,测定了离开骨髓的网织红细胞数量和外周血中网织红细胞数量,观察到电刺激后骨髓和外周血中的网织红细胞数量均有几倍的增加。作者发现,骨髓血流变化对髓腔压力的调节在网织红细胞从骨髓进入循环的过程中起了很大作用。
