title: [Study of the fluid-percussion graded model of experimental brain injury in rats].
abstract: OBJECTIVE
  To study the histopathological aspects of the fluid-percussion graded model of experimental brain injury in rats and the relationship between the fluid-percussion graded model and the clinical grades of brain injury.
  
  
  METHODS
  The graded model of rats was set up by using the device of the improved fluid-percussion model, then we observed the changes of brain tissue of rats.
  
  
  RESULTS
  The fluid-percussion graded model of experimental brain injury could be pathologically graded.
  
  
  CONCLUSIONS
  The pathological grade of the fluid-percussion graded model can be used to evaluate the degree of brain injury in clinic and in experiments.
