OBJECTIVE To investigate the distribution of macrophage (Mphi) infiltration in eutopic and ectopic endometrium throughout the menstrual cycle. DESIGN Controlled clinical study using intact tissue. SETTING Nagasaki University School of Medicine, Nagasaki, Japan. PATIENT(S) Twenty infertile women with pelvic endometriosis and 20 women without(More)
OBJECTIVE To investigate the mitogenic and angiogenic activity of the eutopic and ectopic endometrium throughout the menstrual cycle and to examine whether the activity of the eutopic endometrium is useful to predict greater activity of the ectopic endometrium. DESIGN Controlled clinicopathologic study using intact tissue. SETTING Nagasaki University(More)
BACKGROUND Information is limited regarding the multifunctional role of GnRH agonist (GnRHa) therapy in reproductive diseases. We investigated the pattern of changes in inflammatory reaction, micro-vessel density and apoptosis in the tissues collected from women with endometriosis, adenomyosis and uterine myoma who were treated with or without GnRHa(More)
We describe the preliminary clinical results of a modified method of reduction surgery for easy approach and effective removal of lesions in women with adenomyosis. Old classical reduction surgery was performed in 5 women with imaging diagnosis of adenomyosis who were selected retrospectively among 104 patients undergoing conservative surgery. A transverse(More)
OBJECTIVE To investigate the possible involvement of hepatocyte growth factor (HGF) in the cellular changes of pelvic mesothelium and the association of these changes with macrophage (Mphi) infiltration and the different stages of pelvic endometriosis. DESIGN Controlled clinical study using intact tissue. SETTING Nagasaki University School of Medicine,(More)
We have found that the imprinted H19 gene can be expressed either biallelically or monoallelically in the developing human placentae. H19 biallelic expression is confined to the placenta until 10 weeks of gestation, after which it becomes exclusively maternal, and does not affect allele-specificity or levels of IGF2 expression. The promoter region of H19 is(More)
BACKGROUND Higher activity by early endometriosis than advanced endometriosis has been reported. However, the pattern of activity in individual colored endometriotic lesions in pelvic cavity is unknown. We investigated the variation in activity of the different colored morphologic lesions as proposed by the current revised American Society of Reproductive(More)
Endometriosis, a chronic disease characterized by endometrial tissue located outside the uterine cavity is associated with chronic pelvic pain and infertility. However, an in-depth understanding of the pathophysiology of endometriosis is still elusive. It is generally believed that besides ovarian steroid hormones, the growth of endometriosis can be(More)
BACKGROUND We investigated the expression of the hepatocyte growth factor (HGF) gene and protein by the stromal cells derived from women with or without endometriosis and its regulation by interleukin-6 (IL-6) and tumour necrosis factor alpha (TNFalpha). METHODS Stromal cells immunoreactive to vimentin were isolated from the eutopic and ectopic(More)
BACKGROUND Information regarding macrophage-mediated regulation of hepatocyte growth factor (HGF) by ovarian steroid hormones in women with endometriosis is limited. Therefore, we investigated the regulation of HGF by steroid hormones in isolated macrophages and stromal cells derived from women with or without endometriosis. METHODS We isolated CD68(More)
