title: [c-fos expression in rat's vestibular nucleus under eccentric rotational stimulation].
abstract: OBJECTIVE
  To investigate the c-fos expression in rat's vestibular nucleus under eccentric rotational stimulation and the effects of anti-motion sickness drug (PAPM) on this expression.
  
  
  METHODS
  19 SD rats were divided into three groups: A, B and C. A received as control. B was stimulated by eccentric rotation for 60 minutes. C received injection of PAPM through cavun abdominis 45 min before eccentric rotation. Immunohistochemical method and computerized image analysis were used to map locations of c-fos protein appeared in four vestibular nucleus and to count the masculine cells.
  
  
  RESULTS
  c-fos protein appeared in four vestibular nucleus areas after stimulation, and PAPM had no influence on this expression.
  
  
  CONCLUSIONS
  It suggests that c-fos expression in vestibular nucleus is one of the important way in which vestibular nervous system reacts to outside stimulation and this expression has no direct relationship with the generation and development of motion sickness.
