Endometriosis is associated with dyspareunia, dysmenorrhea and often severe pelvic pain as well as considered a chronic inflammatory disease, defined by the presence of endometrial tissue outside the uterine cavity. An important general con…

Apoptosis plays a critical role in maintaining tissue homeostasis and represents a normal function to eliminate excess or dysfunctional cells. Accumulated evidence suggests that apoptosis helps to maintain cellular homeostasis during the me…

OBJECTIVE: To review the literature on the role of cytokines in the pathogenesis of endometriosis and endometriosis-associated infertility. DESIGN: Pertinent studies were identified by a computer search of MEDLINE. References of selected a…

OBJECTIVE: To compare the expression of interleukin-6 (IL-6) in endometrial and endometriotic cells. DESIGN: Prospective study. SETTING: Department of Obstetrics and Gynecology, Tottori University Hospital, Yonago, Japan. PATIENT(S): Twe…

Endometriosis, a common disease among women of reproductive age, is characterized by the presence of endometrial-like tissue outside the uterus. We and others showed that several cytokine levels, including interleukin-8 (IL-8) and tumor nec…

OBJECTIVE: This study investigated the possible roles of interleukin 6 and soluble interleukin 6 receptor in the growth of endometrial and endometriotic cells. STUDY DESIGN: Endometrial and endometriotic stromal cells were collected from t…

Peritoneal fluid in women with endometriosis contains an increased number of activated macrophages that secrete a variety of cytokines, including interleukin (IL)-6, IL-8, vascular endothelial growth factor, and tumor necrosis factor-alpha …

OBJECTIVE: To investigate the role of interleukin-8 (IL-8) in peritoneal fluid of patients with endometriosis in the pathogenesis of endometriosis. DESIGN: Peritoneal fluid was collected by laparoscopy. Endometrial and endometriotic stroma…

OBJECTIVE: Our purpose was to investigate the relationship between the levels of interleukin-6, interleukin-6 soluble receptor, and tumor necrosis factor-alpha in peritoneal fluid and the size and number of active red endometriotic lesions.…

OBJECTIVE -- The purpose of this study was to compare the potency of the gonadotropin-releasing hormone (GnRH) agonists nafarelin, buserelin, and leuprolide in a newly developed model of experimental endometriosis, thus further characterizi…

OBJECTIVE: To investigate the effects of leuprolide acetate (LA), a GnRH agonist (GnRH-a), and of danazol on the hypothalamic-pituitary-ovarian axis in patients with endometriosis. DESIGN: Ten patients were divided into LA and danazol trea…

The effects of danazol on estrogen production by rat ovaries were investigated. Hypophysectomized immature female rats were injected daily with 2.5 or 5 IU of pregnant mare serum gonadotropin (PMS) and simultaneously daily given vehicle onl…

OBJECTIVE: We attempted to clarify the relationship between luteinized unruptured follicle, which occurs in the early stages of endometriosis, and unexplained infertility. STUDY DESIGN: Seventy patients who had unexplained infertility were…

Effects of danazol, gonadotropin-releasing hormone agonist (leuprolide), and danazol-leuprolide combination on experimental endometriosis were evaluated in female rats. A complete resorption of the fluid and a marked decrease in the volume …

GnRH agonist and synthetic steroid such as Danazol, Medroxyprogesterone acetate (MPA) and Gestrinone are useful for the treatment of patients with endometriosis. These compounds induce atrophy and regression of endometriotic tissue, but the…

The chronic administration of GnRH agonists to women results in the reversible suppression of estrogen production by the ovary. In the present study, the mechanism of the GnRH agonist suppression of estrogen production was investigated in p…

Effects of medroxyprogesterone acetate (MPA) and danazol (1 nM-10 microM) on cultured cancer cells from human endometrial adenocarcinomas obtained by hysterectomy were simultaneously investigated. Of twenty-four endometrial adenocarcinomas …

Since the authors recently reported that danazol inhibits the growth of human endometrial cancer cells in vitro, a clinical trial was initiated to examine whether danazol can regress adenomatous hyperplasia, a precursor of endometrial adeno…

Since we recently found that danazol, an isoxazol derivative of ethinyltestosterone, has a growth-inhibitory effect on human endometrial cancer cells in primary culture, the effects of danazol on a human endometrial cancer cell line (IK-90 …

Based on our recent findings that danazol, an isoxazol derivative of ethinyltestosterone, has a profound growth-inhibitory effect on an established human endometrial adenocarcinoma cell line, the effects of danazol on cancer cells from huma…
