Abstract:
Objective To investigate the effect of neutrophil activation on pathogenesis of preeclampsia. Methods In 22 pregnant women with preeclampsia and 21 normal pregnant women at third trimester, neutrophil activation was examined by flow cytometry to assess the CD11b expression,and the levels of plasma endothelin 1(ET 1) and serum NO - 2 were also measured with no equilibrium radio immunoassay and with Griess assay respectively. Results The expression of neutrophil CD11b was significantly elevated in women with preeclampsia compared with that of normal pregnant women at third trimester [the mean fluorescence index of CD11b were 439 1? 169 1 and 321 2?166 3 respectively, P0 05). Conclusions The neutrophil CD11b expression is significantly elevated in preeclampsia. The increased neutrophil activation may cause the damage of vascular endothelium and result in compensatory increase of NO release in endothelial cells. It suggests that the neutrophil activation may play a key role in pathogenesis of preeclampsia.
