To discover the exact incidence of congenital uterine anomalies among infertile patients, hysterosalpingography was performed on 1,200 married women with a history of repeated reproductive wastage. Out of 1,200 hysterosalpingographies, 188 revealed congenital uterine anomaly (15.7%). The degree of uterine cavity deformity in the anomalies was evaluated(More)
Our recent 7-year clinical survey showed that among the 1120 women with repeated spontaneous abortions registered in this clinic, 2898 out of a total of 3216 pregnancies (90.1%) had terminated in spontaneous abortion. Among these wastages, 84.2% occurred before 12 weeks of gestation, and 11.1 percent occurred between 12 and 15 weeks. Through routine(More)
To evaluate a possible physiological role of Interleukin-2 (IL-2) in the control of Luteinizing hormone (LH), Follicle stimulating hormone (FSH) and Prolactin (PRL) release, conscious, ovariectomized (OVX) rats were given injections of IL-2 into the third ventricle. The third ventricular injection of IL-2 induced a significant decrease in plasma LH levels(More)
We investigated the infection rate of Chlamydia trachomatis in sexual partners who had pregnant wives with C. trachomatis diagnosed by means of serum-antibody test (Ipazyme) or antigen test (Chlamydiazyme, IDEIA-chlamydia). Antibody-positive rate was 60.4% (90/149 cases), and antigen-positive rate was 7.4% 11/149 cases). All cases with Chlamydial antigen(More)
Habitual abortion is sometimes an incurable pathogenetic state. Even more serious to both the patient and gynecologist is that the incidence of repeated reproductive wastage is higher in subsequent pregnancies. We registered more than 1,000 women with repeated spontaneous abortions in this clinic for 5 years and analyzed their pathogenesis for the wastages(More)
We previously reported that a blockade of GnRH receptor activation inhibited the already-initiated C-kinase pathway(s). We tried to investigate whether this finding is a general phenomenon or not. In this study, we employed three GnRH antagonists, [D-Phe2,Pro3,D-Phe6]-GnRH, [Ac-D-Nal-Ala1,D-pCl-Phe2,D-Ser(Rha)6]-GnRH, and(More)
PROBLEM Recently the protective value of high-dose intravenous immunoglobulin (IVIG) in the treatment of unexplained recurrent miscarriage has been reported to be similar to that of conventional immunotherapy with paternal leukocytes. We examined the effect of IVIG treatment on the cellular and humoral level of maternal immunity to demonstrate the possible(More)
The possible causes of early pregnancy failure in one thousand, three hundred and seventeen women (n = 1,317) with a history of repeated reproductive wastage were analysed and the results of treatment for each etiology were evaluated. Out of 1,200 hysterosalpingographies, 188 (15.7%) congenital uterine anomalies were detected and the degree of each uterine(More)
In order to approach an understanding of the mechanisms of fetal death in patients with antiphospholipid syndrome we investigated the association between protein C activity and anticardiolipin antibody. Protein C activity in vivo was decreased in some patients with recurrent fetal loss and a high ACA titer. This study suggests that anticardiolipin antibody(More)
