The craniocerebral ballistics, craniocerebral pathology, serum and cerebrospinal flu-id total lactate dehydrogenase, blood-brain barrier permcabalities, and the pathophysiology ofcardiovascular and respiratory systems were studied. These results suggest that: 1. These injuries ofhigh-velocity missile can all cause general brain damage and intracranio-hematomas ; 2. The severityof the wound depends on the site of the injury, the kinetic energy of the missile force and the effectof the temporary cavity ; 3. The brain injury can seriously damage the blood brain barrier, leadingto brain edema ; 4. The dysfunction of respiratory and cardiovascular system is the fatal complicationendangering the life of the subjects ; 5. Estimating serum and cerebrospinal fluid total lactatedehydrogenase is a simple and valuable way to judge the severity and prognosis of this injury.展开更多
