OBJECTIVE: To investigate the impact of an IVF program on serum levels of tumor markers CA 125, tumor-associated trypsin inhibitor, free hCG beta-subunit, and free glycoprotein hormone alpha-subunit. DESIGN: A prospective controlled clinic…

Primary menorrhagia, IUD side effects and endometriotic symptoms may be a result of excessive PG release in the reproductive organs. These conditions and symptoms can be prevented or markedly alleviated by a PG synthesis inhibitor, such as …

Medical 'oophorectomy' by GnRH agonist or danazol is an effective treatment for endometriosis. Since increased bone loss is a potential risk of hypoestrogenism, we compared the effect of nafarelin and danazol treatment on bone metabolism. T…

The effects of nafarelin (400 micrograms daily; 12 patients) and danazol (600 mg daily; 6 patients) on serum lipoproteins, high density lipoprotein (HDL) subfractions, and apoproteins-A-I and -A-II were studied. Lipoproteins were fractionat…

We studied the effect of ovarian cancer and its chemotherapy on the urinary excretion of prostacyclin (PGI2) and thromboxane A2 (TxA2) hydration and metabolic products. In six patients we measured 6-keto-PGF1 alpha and 2,3-dinor-6-keto-PGF1…

The gynecologic and obstetric implications of the smooth muscle-relaxing, antiaggregatory prostacyclin and its endogenous antagonist, thromboxane A2, are reviewed. In addition to the vascular wall and circulating platelets, which are primar…

To study peritoneal fluid (PF) prostaglandin (PG) in infertile women, 6-keto-PGF1 alpha (a breakdown product of prostacyclin) and thromboxane B2 (T X B2) (a metabolite of T X A2) were assayed with radio-immunoassays from PF samples collecte…

To elucidate the roles of prostaglandins in peritoneal fluid and sex steroids in patients with endometriosis (N = 29), tubal disorders (N = 15), and unexplained infertility (N = 13), assays were performed using 6-keto-prostaglandin F1 alpha…

To study the production of prostacyclin (PGI2) and thromboxane A2 (TxA2) in endometriosis in vitro, samples of endometriotic tissue taken during operation from 6 women were superfused for 4.5 hours in 95% O2/5% CO2 at 37 degrees C, and the …
