BACKGROUND Angiogenesis and vascular remodeling play critical roles in the cyclical growth and regression of endometrium. They also appear to play roles in the pathogenesis of endometriosis. METHODS AND RESULTS Supernatants were collected from cultured endometrium isolated from women with and without endometriosis. These supernatants induced endothelial cell proliferation and angiogenesis in ...

Local endometrial aberrations are thought to be the major contributing factor to essential menorrhagia. Here we have examined the role of endometrial angiogenesis, the growth of new blood vessels, in essential menorrhagia. Our study tested two hypotheses: firstly that angiogenesis is disturbed in the endometrium of women with menorrhagia; and secondly that when menstrual blood loss is decreased...

Metastatic carcinoma from extragenital sites to the uterus, particularly endometrium, is rare and usually a sign of advanced disease. It necessary differentiate between metastatic primary tumours since treatment prognosis are entirely different. We discuss case 61-year-old woman who presented with postmenopausal bleeding due breast cancer endometrium. She had been diagnosed on tamoxifen for six...

AIM To obtain insight into the effects of oestrogen on extracellular matrix (ECM) in the postmenopausal endometrium. METHODS The distribution of the components of the ECM, including collagen types I, III, IV, and VI, and laminin, was investigated in the human postmenopausal endometrium by an indirect immunofluorescence method with specific monoclonal antibodies and a polyclonal antibody. Coll...

BACKGROUND Heavy menstrual bleeding and dysmenorrhea are two top complaints from women with symptomatic adenomyosis, yet their etiology is poorly understood. Tissue factor (TF) has been shown to be upregulated in endometriosis and at the endometrial bleeding sites of women with long-term progestin only contraception. We sought to investigate the expression and localization of TF in eutopic and ...

Prolactin (PRL) is a multifunctional signaling molecule best known for its role in regulating lactation in mammals. Systemic PRL is produced by the anterior pituitary, but extrapituitary PRL has also been detected in many tissues including the human endometrium. Prolactin is essential for pregnancy in rodents and one of the most dramatically induced genes in the endometrium during human pregnan...

Background MIF via its receptor, CD74, initiates a signaling cascade that leads to proliferation and survival of cells. Also, MIF binding to CD74 activates p38 signaling pathways that lead to positive effect on the expression of COX-2. The aim of this study was to evaluate the gene expression profile of MIF, CD74 and COX-2 in normal, ectopic and eutopic endometrium during menstrual cycle. The e...

Pregnant BALB/c mice were inoculated intravaginally on day 5 of gestation with the Chlamydia trachomatis mouse pneumonitis biovar. Animals that received 10(5), 10(6), or 10(7) inclusion-forming units (IFU) of C. trachomatis delivered prematurely on days 15 to 16 of gestation. A focal inflammatory infiltrate was observed in the wall of the uterus on the day 14 of gestation in animals inoculated ...

We presents results of a study on endometritis modeling in rats with double intravaginal administration bacterial lipopolysaccharide (LPS). The established endometrial inflammatory process was accompanied by decrease the weight animals, an increase uterus, neutrophilic infiltration, edema, and overexpression cyclooxygenase endometrium 30-45 days after start induction. Local use plasma enriched ...
