OBJECTIVE: Various types of malignancy can develop in patients with endometriosis. Enhancing mural nodules have been reported as an imaging characteristic of malignant transformations. We evaluated contrast-enhanced MR imaging to determine …

OBJECTIVES: Although the physiologic and pathologic roles of endothelin-1 in reproduction have been investigated, little is known about human uterine tissue levels. We studied the levels of immunoreactive endothelin-1 and immunoreactive big…

OBJECTIVE: To investigate the potential role of prostaglandins (PGs) in tubal function in endometriosis. SUBJECTS: Fallopian tubes were obtained from 36 women undergoing abdominal total hysterectomy. METHODS: PG production of the human fa…

The role of prostaglandins (PGs) in dysmenorrhea of endometriosis is poorly understood. The relationship between dysmenorrheic severity and prostaglandin production was investigated in endometriosis. Slices of normal myometrium, adenomyosis…

In order to investigate the production of eicosanoids in human endometrium, myometrium, leiomyoma, adenomyosis, normal ovary, non-endometrial cyst and endometrial cyst, slices of each tissue were incubated. 6-Keto-prostaglandin (PG) F1 alph…

To determine the effects of nocturnal hyperprolactinemia on luteal function and galactorrhea we studied six diurnal normoprolactinemic women with regular menstrual cycles. The diurnal serum levels of prolactin (PRL), luteinizing hormone (LH…

In order to investigate whether prostanoids are involved in the pathophysiology of endometriosis, prostaglandin and leukotriene concentrations in peritoneal fluid were measured in adenomyosis, ovarian chocolate cyst and uterine leiomyoma. I…

In order to investigate prostacyclin production by human myometrium, uterine cervix and leiomyoma, slices of each tissue were incubated. The 6-keto prostaglandin F1 alpha concentration of the incubation medium was measured by radioimmunoass…
