title: [The effect of cold- and heat-natured medicines on 5-HT and NE cells and nerve fibres in rat's brain, pituitary and adrenal].
abstract: OBJECTIVE
  To study how cold- and heat-natured medicines act on 5-HT and NE cells in the brain, pituitary and adrenal of rats.
  
  
  METHODS
  Based on immunohistochemical method, the specific anti-TH and anti-5-HT sera were used to observe the changes of 5-HT and NE cells in brain and adrenal as well as fibres in pituitary. The contents of these two transmitters in brain were also determined by fluoriphotometry.
  
  
  RESULTS
  Cold-natured medicines made the staining of 5-HT cells deeper and NE cells lighter, while heat-natured medicines act by contraries.
  
  
  CONCLUSIONS
  Cold-natured medicines increase the content of 5-HT in brain and decrease the content of NE, while heat-natured medicines work the other way around. The morphologic changes are consistent with the functional ones.
