  • Title: [Determination of platelet activating factor and platelet associated IgG in pregnancy-induced hypertension].
    Author: Zhang S, Zhang Y, Liu B.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 1996 May; 31(5):296-8. PubMed ID: 9206185.
    Abstract:
    OBJECTIVE: To determine the levels of platelet activating factor (PAF) and platelet associated IgG (PAIgG) in pregnancy-induced hypertension (PIH). METHODS: Twenty-eight cases of normal pregnant women and 44 cases of PIH (moderate, n = 23; severe, n = 21) were enrolled in this study. The plasma level of PAF was measured using platelet aggregation bioassay, and determination of PAIgG was performed by ABC-ELISA (enzyme-labeled immunosorbent assay) method. RESULTS: The level of plasma PAF in PIH patients (5.02 +/- 1.93 micrograms/L) was significantly higher than that in the controls (1.16 +/- 0.22 micrograms/L, P < 0.01). There was no difference between the levels of PAF in moderate PIH and severe ones. The level of PAIgG in PIH (6.3 +/- 4.9 micrograms/10(2)) was significantly higher than that in the control (3.8 + 1.8 micrograms/10(2), P < 0.05). CONCLUSIONS: PAF may be involved and play an important role in the pathophysiological changes in PIH. Autoimmunological reaction of platelets may exist in pregnant women with PIH.
