title: [Effect on gastrointestinal functions of Polygonum paleaceum].
abstract: OBJECTIVE
  To study the effect on gastrointestinal functions of Polygonum paleaceum Wall.
  
  
  METHODS
  Defecation reflex, gastric emptying, motility of the gastroinestinal tract of mice and isolated intestinal smooth muscle of rabbits were used.
  
  
  RESULTS
  Polygonum paleaceum Wall could inhibit defecation reflex and depress the motility of the gastrointestinal tract, delay gastric emptying in mice. It also had analgesia action, but didn't affect rabbit intestinal contraction spontaneously or induced by acetylcholine (Ach) in vitro.
  
  
  CONCLUSIONS
  It suggested that Polygonum paleaceum Wall possessed the action on gastrointestinal functions.
