An experimental Stuay on the spinal cord injury.
The auther made an experimental study with rabbits on the radiological as well as histological findings of the spinal cord injuries which were caused by a fall from 3.75 meter's height.
As a result of this study the following points shoud be noted.
(1) Even in the cases with negative X-ray findings the fractures of spinal bones were proved with the anatomic studies,
(2) Tigrolysis which was found in the ganglion cells much higher than the point of bone lesion, to indicate that the clinical signs often observed in the points of spinal cord higher than the damaged bone could be caused by a direct trauma on the remote area.
(3) As possible causes of the edema in the spinal cord, the rhexis bleeding found in the spinal cord, should be added.
(4) Regemeration of nerve cells of the spipal cord was not detected in all of the cases.
(5) In one of the cases some inflammatory change was observed in the spinal cord, which requires further elucidation.
The above experiment was performed on the animal which fell from a place of 3.75 meter's height.
Accordingly the further study schould be made by changing the height of the place.
