title: [Changes in plasma von Willebrand factor and nitric oxide levels in patients with pregnancy induced hypertension].
abstract: OBJECTIVE
  To study the changes and clinical significance of plasma von Willebrand factor (vWF) and nitric oxide (NO) levels in patients with pregnancy induced hypertension (PIH).
  
  
  METHODS
  Plasma vWF and NO were detected by ELISA and Griess assay respectively in 36 patients with PIH and 18 healthy pregnant women.
  
  
  RESULTS
  The levels of plasma vWF in patients with moderate and severe PIH increased significantly. than those in healthy pregnancy. The levels of plasma NO in patients with PIH were significantly lower than those in healthy pregnancy. The higher the vWF levels or the lower the NO levels, the more severe in PIH. There was a negative correlation between the plasma vWF and NO levels.
  
  
  CONCLUSIONS
  The results suggest that plasma vWF and NO concentration can be used as indicators in the judgement of the severity of PIH.
