title: [Determination of beta-endorphin in hypothalamus of rat with primary trigeminal neuralgia].
abstract: OBJECTIVE
  To determine the level and the role of beta-endorphin in hypothalamus of rat with trigeminal neuralgia.
  
  
  METHODS
  The animal model of primary trigeminal neuralgia in rat was established, the contents of beta-endorphin were measured by radioimmunoassay techniques.
  
  
  RESULTS
  The beta-endorphin of hypothalamus in experimental group was significantly lower than other groups (P < 0.01).
  
  
  CONCLUSIONS
  Beta-endorphin may play important roles in primary trigeminal neuralgia.
