To assess human exposure to bisphenol A (BPA) over a 10-year period, BPA concentrations in maternal serum (MS) and amniotic fluid (AF) obtained at early second trimester were determined. ELISA was used to measure BPA in 200 MS/AF pairs in women carrying fetuses with normal karyotypes (Group I) and in 48 pairs with abnormal karyotypes (Group II). In Group I,(More)
BACKGROUND The aim of this study was to assess the natural killer (NK) cell and natural killer T (NKT) cell populations and cytokine expression of T-helper (Th) cells in the endometrium of women who suffered from unexplained repeated miscarriage (RM). METHODS The percentages of NK cells, NKT cells and CD4(+) cells expressing intracellular interferon(More)
alpha-Glucosidase activity was assayed in polymorphonuclear cells and lymphocytes from human peripheral blood with 4-methylumbelliferyl-alpha-D-glucopyranoside as substrate in the presence of sodium taurocholate. The pH vs. activity curve of the alpha-glucosidase indicated that differential estimation between acid and neutral alpha-glucosidases was(More)
To study whether the renin-angiotensin system is related to hyperuricemia in hypertension, the serum concentration of uric acid was determined in 96 patients with various types of hypertension and various degrees of plasma renin activity (PRA). In malignant hypertension, both PRA and the serum uric acid level were higher than in essential hypertension; but(More)
OBJECTIVE To investigate the relationships between recurrent pregnancy loss and single nucleotide polymorphisms (-634C-->G and -174G-->C genotypes) in the promoter region of the interleukin (IL)-6 gene in the Japanese population. DESIGN A case-control study. SETTING Obstetrics and gynecology department of a university hospital. PATIENT(S) Cases were(More)
PROBLEM The aim of this study was to assess the role of natural killer (NK) cells in pregnant women with a history of recurrent spontaneous abortion (RSA). METHOD OF STUDY Consecutive 66 pregnant women with a history of RSA were prospectively assessed for peripheral NK cell activity, percentage of the NK cell subsets, and subsequent pregnancy outcome.

The etiology of recurrent pregnancy loss (RPL) remains unclear, but it may be related to a possible genetic predisposition together with involvement of environmental factors. We examined the relation between RPL and polymorphisms in four genes, human aryl hydrocarbon (Ah) receptor, cytochrome P450 (CYP) 1A1, CYP1A2 and CYP1B1, which are involved in the(More)
OBJECTIVE The aim of this study was to establish the risk of postpartum thyroid dysfunction (PPTD) in women who had normal thyroid function during pregnancy and no history of thyroid disease. DESIGN Four thousand and twenty-two consecutive pregnant women were screened for thyroid function and antithyroid antibody. Among women with normal thyroid function(More)
Women with antithrombin (AT) III deficiency are prone to pregnancy-associated venous thromboembolism. We report 2 cases with genetically confirmed ATIII deficiency, one with a mutation in exon 3A and the other with an exon 4 deletion, in whom the pregnancies were successfully managed with prophylactic therapies for thrombosis. A 35-year-old pregnant woman(More)
