[Detection of platelet activation by flow cytometry in patients with pre-eclampsia].

OBJECTIVE: To explore the clinical significance of expression alterations of static and activated platelet glycoprotein CD41a, CD62p, and CD63 in patients with pre-eclampsia. METHODS: We used non-washing immunolabeling technique for fluorescence labeling of the static and activated platelet with CD41a, CD62p, and CD63 monoclonal antibodies of the blood samples from 16 patients with pre-eclampsia, 15 women with normal pregnancies and 20 healthy subjects. The expression of the monoclonal antibody was detected by flow cytometry. RESULTS: The average static and activated platelet glycoprotein CD41a, CD62p, and CD63 expression levels in patients with pre-eclampsia were apparently higher than those of the normal pregnant women (P<0.01), while the comparison between the latter and the control group did not reveal any significant differences (P>0.05). CONCLUSION: High levels of platelet glycoprotein CD62p and CD63 expressions are present in patients with preeclampsia, suggesting the presence of platelet activation in these patients.
