  • Title: [Immunopathological study on the uterine spiral arteries in pregnancy-induced hypertension].
    Author: Lin QD.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 1992 Jul; 27(4):209-10, 249-50. PubMed ID: 1291215.
    Abstract:
    The uterine spiral arteries were studied by the immunohistochemical ABC method in 30 cases of Pregnancy Induced Hypertension (PIH) and 10 cases of normal pregnant women. Depositions of IgM and/or C3 on the vessel wall were significantly observed only in PIH cases (15 cases, 50.0%; P < 0.05). Depositions of IgG were seen in 5 cases of PIH 16.7% showing significantly decrease. (P < 0.001), as compared with the normal pregnant women (9 cases, 90.0%). The results suggest that PIH is related to chronic rejection reaction resulting possibly from the decrease of local immunosuppression in pregnancy. Meanwhile the positive stain of IgG, IgM and C3 seen in the nuclei of decidual cells in some of PIH cases were discussed.
