title: [The changes of suppressor T-cells function in patients with RAU].
abstract: OBJECTIVE
  To study the change of suppressor T-cell function in patients with RAU.
  
  
  METHODS
  Samples of 12 patients with RAU active phase were studied by it suppressor assay.
  
  
  RESULTS
  The T-cell suppress rates at ConA 1,2,4 and 8 mg/L were 60%, 40%, 27% and 20% respectively, and were evidently lower when compared with normal controls' 72%, 56%, 41% and 34% (P < 0.05).
  
  
  CONCLUSIONS
  The suppressor T-cell function may be depressed in RAU patients.
