Abstract:
To study the significance of the pathological changes of axon and myelin sheath in injured brainstem.The neurofilament and myelin basic protein was demonstrated immunohistochemically,and the pathological changes of axons and myelin sheathes in human brainstem following trauma were observed.In the injured brainstem,irregular swelling and disconnecting axons could be found as early as 0 5h after injury, while pathological changes in myelin sheaths such as tortuous change,partial peeling off from axon and intermittent disappearance could be observed at 19～22h after injury.However,in the normal brainstem,there were no evident changes in axons and myelin sheaths.Pathological changes of axon and myelin sheath in brainstem would occur after trauma,which could be used for postmortem diagnosis of brainstem injury.
