title: [Inhibition of rhodiola on the growth of EVC-304 cell line].
abstract: OBJECTIVE
  To observe the effect of rhodiola on human umbilical vein endothelial cell line EVC-304.
  
  
  METHODS
  EVC-304 was cultured and divided into two groups: control group and rhodiola-treated group. Three days after treatment, cell survival rate-drug concentration curve was obtained by counting the survival cells, and cells in each group were stained by Wright's stain and observed under microscope. Cell cycle was determined by flow cytometry (FCM).
  
  
  RESULTS
  The survival cells in rhodiola-treated group was much less than those in control group. More cells in rhodiola-treated group stayed in G(1) phase while less in S phase when compared with those in control group by FCM.
  
  
  CONCLUSIONS
  Rhodiola can inhibit the growth of human endothelial cell line EVC-304, perhaps through inhibiting the proliferation of the cells. This may lay the foundation for the mechanism study and clinical application of rhodiola in prevention of pulmonary artery hypertension.
