PROBLEM: The aims of this study were to establish a mouse model of endometriosis and adenomyosis and to elucidate the necessity of reduced natural killer (NK)-cell and T-cell activities in the establishment of endometriosis and adenomyosis.…

PROBLEM: To establish an enzyme-linked immunosorbent assay (ELISA) for determining the levels of antibodies to transferrin and alpha 2-HS glycoprotein in the serum of women with and without endometriosis. METHOD OF STUDY: Serum samples wer…

PROBLEM: Elevated levels of activated macrophages are associated with endometriosis, but their role in the etiology of the disease is uncertain. The current study was undertaken to examine whether activated macrophages could modulate perito…

PROBLEM: Interleukin-12 (IL-12) is produced mainly by monocytes/macrophages, and it induces proliferation and cytotoxicity of T-cells and natural killer cells. In women with endometriosis, natural killer cell activity in the peritoneal flui…

PROBLEM: The objective of this study was to evaluate the correlation of menstrual CA-125 levels with pregnancy rates (PRs) after 6 months of treatment for infertility. METHOD: The sample consisted of a heterogenous group of 160 women who s…

PROBLEM: Factors regulating the development, growth, and differentiation of endometrial cells of endometriotic lesions are poorly understood. To investigate the paracrine-autocrine regulation of ectopic endometrial cell growth, the expressi…

PROBLEM: An immunologic basis has long been considered to be very important in the pathogenesis of endometriosis. Interactions of the peritoneal cells, which comprise macrophages, B cells, T cells, natural killer (NK) cells, and retrograde …

PROBLEM: Hyperactivated macrophages are implicated in the pathophysiology of endometriosis-associated infertility. This study investigates transferrin receptor expression (CD71) as a marker of hyperactivity in peritoneal macrophages of infe…

PROBLEM: Identifying the endometrial antigens inciting autoimmunity is important in setting up an antibody assay for a non-invasive diagnosis and clinical monitoring of endometriosis. METHODS: Two-dimensional gel electrophoresis of endomet…

PROBLEM: To determine whether infertile patients with endometriosis have serum antiendometrial antibodies. METHODS: Sera from 40 infertile patients with or without endometriosis were tested by cell enzyme-linked immunosorbent assay (ELISA)…

PROBLEM: To determine the effect of estrogen deficiency on populations of immune cells in rats with autotransplanted endometrium. METHOD OF STUDY: Autologous endometrial segments were implanted in the peritoneum of rats. Leukocyte subsets …

Some cases of unexplained recurrent pregnancy loss may be due to embryotoxic factors present in the mother's serum. In vitro assays have been devised to study the effect of these factors on pre-implantation, peri-implantation, and somite st…

PROBLEM: Are T cell subsets including gamma delta T cells. HLA antigens or adhesion molecules, expressed in eutopic and ectopic endometria in patients with endometriosis and adenomyosis? METHODS: Subjects consisted of 23 patients with aden…

PROBLEM: The mechanism of infertility in women with endometriosis remains obscure. In this context the role of peritoneal macrophage's sperm phagocytic ability in infertile women with and without endometriosis was investigated. METHOD: Ana…

PROBLEM: We have recently observed that the regression of corpora lutea (CL) in women during the reproductive period of life is accompanied by a diminution of Thy-1 differentiation protein release from vascular pericytes and an accumulation…

Reproductive life table analysis indicates that the majority of reproductive failures result from post fertilization failures, whether before or after implantation. It is important to have a set of tests to clarify the diagnosis of the repr…

PROBLEM: Comparison and characterisation of different lymphocyte subsets in the endometrium of endometriosis patients and in healthy women on every day of the menstrual cycle with special emphasis on the CD4:CD8 ratio in the endometrium. M…

PROBLEM: Development and progression of endometriosis have been suggested to be related to a defect of NK cells in the ability to eliminate endometrial fragments regurgitated with menstrual debris in ectopic sites. However, it has not been …

The present study demonstrates several aspects of endometrioma cells in culture, namely, 1) cell growth, proliferation, and morphology, 2) effect of cell culture on estrogen and progesterone receptor concentration, 3) effect of estradiol, p…

PROBLEM: Our previous study reported that peritoneal natural killer (NK) cytotoxicity and CD3+CD25+ lymphocyte subpopulation were suppressed in women with advanced endometriosis. Whether these phenomena are general for all stages of endomet…

PROBLEM: This study was undertaken to determine whether specific binding activities against endometrial proteins in sera of patients with endometriosis are detectable and, if so, to identify endometrial antigens involved in autoimmunity in …

PROBLEM: Previous studies have established that in vitro proliferation of endometrial cells is enhanced by peripheral blood monocytes (PBM) and suppressed by peritoneal macrophages (PM) from patients with endometriosis but only suppressed b…

PROBLEM: Macrophages are implicated in the pathophysiology of endometriosis and are influenced by anti-inflammatory steroids as well as anti-oxidants. METHODS: We tested the effect of RU-486, an antiprogesterone, antiglucocorticoid and an …

PROBLEM: The aim of this study was to characterize the phenotype of peritoneal lymphocyte and macrophage populations in mild versus severe endometriosis. METHOD: Using dual staining, antigen expression on peritoneal leukocytes from 24 wome…
