title: [Effect of overall alkali of Tongbiling on CD69 expression activated mouse T lymphocytes].
abstract: OBJECTIVE
  To investigate the effect of overall alkali of Tongbiling(TBL) on CD69 expression on activated mouse T lymphocytes and its possible mechanism.
  
  
  METHODS
  Phorbol 12,13-dibutyrate(PDB) or concanavalin (ConA) were added successively into mouse lymphocytic culture with various concentration of overall alkali TBL. After 24 hours, CD69 expression rate on mouse T lymphocytes activated with PDB or ConA was analyzed by flow cytometry.
  
  
  RESULTS
  Overall alkali TBL could significantly down-regulate CD69 expression in a dose-dependent manner.
  
  
  CONCLUSIONS
  Overall alkali TBL can significantly inhibit CD69 expression on activated mouse T lymphocytes. This study provided an experimental basis for application of overall alkali TBL to treatment of rheumatoid arthritis.
