title: [Study on the growth-inhibiting effect of anticancer ketonon on lung cancer cell line and its mechanism].
abstract: BACKGROUND
  To observe the growth-inhibiting effect of anticancer ketonon on A549 cell line and PLA-801D cell line and to explore its mechanism based on the antineoplastic effects of Tanshinon.
  
  
  METHODS
  A549 and PLA-801D cell lines were treated with anticancer ketonon by techniques of cell culture in vitro . The growth curves and dose-effect curves were drawn up. The ability of clone formation was determined. It was observed and analysed by light microscopy and flow cytometry.
  
  
  RESULTS
  The growth of A549 and PLA 801D cell lines was evidently inhibited. Ability of clone formation was inhibited. The apoptosis index of cells was increased after treated with anticancer ketonon and the cell cycle was blocked at G0/G1 phase.
  
  
  CONCLUSIONS
  Anticancer ketonon can significantly inhibit the growth of human lung cancer cells probably through inducing the apoptosis of cancer cells.
