[Changes in plasma von Willebrand factor and nitric oxide levels in patients with pregnancy induced hypertension]
1Department of Obstetric and Gynecology, Central South University, Changsha 410011, China.
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.
Conclusion:
The results suggest that plasma vWF and NO concentration can be used as indicators in the judgement of the severity of PIH.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
