急性出血に於ける骨髓の態度に関する研究 第二編 神経切断が瀉血による骨髄血球動員に及ぼす影響に就て

Following the experiments stated in Part 1, in order to examine the blood cell mobilization function of the bone marrow from the viewpoints of central nervous system control and peripheral nervous system control, the blood picture of the V. nutricia was observed after transecting the spinal cord at a higher level, as did KOMIYA, and also after extirpating the abdominal sympathetic nerve, as did MORIKAWA. The results are as follows: 1) The marked mobilization of the bone marrow depot blood cells, which is seen 1 to 2 hours after the bleeding, was not hindered by the transection of the higher-level spinal cord. Therefore, the mobilization is little effected by the central blood cell control nerves. 2) Mobilization of the bone marrow depot blood cells is not much effected by the extirpation of the abdominal sympathetic trunk. Therefore, its control by the peripheral nerves is negligible. 3) The dilation or contraction of the nutricia vessels do not have a primary significance in the mobilization of the bone marrow blood cells after bleeding.
