Endometriosis may be the precursor of clear cell or endometrioid ovarian cancer. In this review, we focus on the prevalence of endometriosis in ovarian cancer and related clinical and epidemiological issues. According to 15 published report…

PROBLEM: In the quest for possible involvement of stem cell factor (SCF), a cytokine known to have multiple effects, in the pathogenesis of endometriosis, we evaluated concentrations of SCF in peritoneal fluid (PF) of women with or without …

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been suggested as a possible etiologic factor for endometriosis, a condition in which endometrium-like tissues are present outside the uterus. The prevailing view pertaining to the origin of en…

The concentrations of hepatocyte growth factor (HGF) in peritoneal fluid (PF) from women with endometriosis (n = 36) and without endometriosis (n = 40) were measured. All of the PF samples examined contained detectable concentrations of HGF…

Ovarian endometrial cysts, one of the typical manifestations of endometriosis, are classified as tumor-like lesions rather than as neoplasms. Clonality analysis provides important information on the histogenesis and progression of neoplasti…

Vaginal agenesis combined with a functional uterus is a rare condition in which treatment modalities that preserve reproductive function are controversial. A 21 year old female presented with congenital vaginal agenesis combined with cervic…

OBJECTIVES: This multicenter prospective study of buserelin acetate (Suprecur) therapy for endometriosis was performed in order to examine pregnancy rates and the recurrence of endometriosis 1 year after the end of intranasal administration…

Cloacal dysgenesis is frequently associated with uterine anomalies. We report a case of pregnancy which resulted in an abortion in a woman with a persistent cloaca. Presumptive diagnosis before operation was ectopic pregnancy of the left tu…

CrossLaps peptide [Glu-Lys-Ala-His-Asp-Gly-Gly-Arg], a part of the C-telopeptide of the alpha 1-chain of type I collagen of bone, is a recently developed biochemical marker of bone turnover. In this study, the clinical utility of measuremen…

Ovarian endometrial cysts, one of the typical manifestations of endometriosis, are generated by the retention of cyclic hemorrhages and are classified as tumor-like lesions rather than neoplasms. Clonality analysis provides important inform…

OBJECTIVE: The objective of this study was to examine the occurrence of ovarian endometriosis in epithelial ovarian cancer in Japan. METHOD: The presence of ovarian endometriosis was determined by reviewing the sections of resected specime…

Endornetriosis usually remains localized to the peritoneal cavity and intrathoracic endometriosis, in both its pleural and parenchymal forms, is very rare [l]. It can manifest as catamenial pneumothorax, catamenial hemoptysis, or an asympto…

Decidualized tissues are characterized by the intensive outgrowth of the microvasculature. Several angiogenic factors are assumed to be involved during the drastic change in the vasculature occurring in the process of decidualization. We ex…

ObjectiveTo investigate whether a relationship exists between personality and expression of pain in women with endometriosis.Study designWith use of the Rosenzweig picture frustration study, the personality of women with endometriosis was a…

ObjectiveOur aim was to examine the relationship between the levels of cytokines in peritoneal fluid and its embryo toxicity.Study designThe levels of interleukin-1 and tumor necrosis factor were measured in peritoneal fluid from infertile …

Glycogen content in endometrium with endometriosis was about half of that without endometriosis at the secretory phase, whereas no difference was found in the proliferative phase. The activity of glycogen synthetase in endometrium with endo…

A primary cell culture of endometriotic cells was established to examine the hormonal regulation of endometriosis. The addition of estradiol had no effect on the DNA synthesis of cultured endometriotic cells. Progesterone at 10(-7) M caused…

A primary cell culture of endometriotic cells was established to examine the hormonal regulation involved in the growth of endometriosis. The addition of estradiol had no effect on the DNA synthesis of cultured endometriotic cells. Progeste…

To clarify the mechanism of infertility associated with endometriosis (EM), the effect of peritoneal fluid (PF) on early embryogenesis was examined. The addition of PF (5%) had no effect on the development of mouse 2-cell embryos. Since the…

The actions of danazol on the release of gonadotropins and prolactin (PRL) were investigated by using a culture of rat anterior pituitary gland cells. The addition of danazol in the range between 10(-9) M and 10(-5) M elevated the levels of…

1. Regulatory mechanism of cell growth of endometriosis in comparison with endometrium. Estradiol alone has no growth-promoting effect on both endometriotic and endometrial cells. Epidermal growth factor (EGF) stimulates cell growth of both…
