Abstract:
By inflicting the hindlimbs of dogs with steel bullets in different velocities, a model of traumatic stress was reproduced. The contents of myelin basic protein (MBP) and endothelin 1 (ET1) in cerebrospinal fluid (CSF) were determined with ELISA and radioimmunoassay methods, and the wltrastructural changes in limbic system were studied with neuropathological techniques. The MBP level and ET1 contents increased markedly in CSF, and neuronal degeneration and nerve fiber demyelination were seen in the hypothalamus and hippocampus in high speed missile group. The results indicate that the hypothalamus and hippocampus were vulnerable in severe injury of remote tissues,and it might be one of the important neuropathological basis for changes in the early stage of posttraumatic stress disorder (PTSD). The results also suggested that the CSF MBP and CSF ET1 determinations might serve as sensitive indicators for central nervous system damage in stress disorder following severe injury.
