Difficult to detect, ovarian cancer typically presents at an advanced stage. Significant progress has been achieved in the treatment of ovarian cancer with therapeutics focused on DNA replication or cell division. However, despite sensitivity to induction chemotherapy the majority of patients will develop recurrent disease. Conventional agents for recurrent disease offer little in terms of long...
objective(s): to evaluate the protective effect of erdosteine, an antiapoptotic and antioxidant agent, on torsion–detorsion evoked histopathological changes in experimental ovarian ischemia-reperfusion (ir) injury. materials and methods: eighteen female wistar albino rats were used in control, ir, and ir+edosteine (ir-e) groups, (n=6 in each). the ir-e group received the erdosteine for seven da...
Factors that control recruitment of theca cells from ovarian stromal-interstitial cells are important for early follicle development in the ovary. During recruitment, theca cells organize into distinct layers around early developing follicles and establish essential cell-cell interactions with granulosa cells. Recruitment of theca cells from ovarian stromal stem cells is proposed to involve cel...
The cyclical changes in the gonadotropins stimulate ovarian follicular development either to the ovulatory stage or to undergo atresia. One such intrafollicular factor may be inter-cellular communication via gap junctions. We have examined the effects of two agents (retinoids and alkanols), known to disrupt or uncouple gap junction, on FSH-stimulated LH receptor induction and progestrone synthe...
Background: Polycystic ovarian syndrome (PCOS) is the commonest cause of secondary infertility. Laparoscopic ovarian drilling has widely been used for induction of ovulation in polycystic ovarian syndrome patients resistant to clomiphene citrate. 80% patients ovulated after treatment and 60% patient conceived either spontaneously or after treatment with medication to which they are previously r...
OBJECTIVES To report a rare case of ovarian tumor with an unusual presentation; an ovarian pregnancy luteoma with massive ascites and elevated CA125 after ovulation induction therapy. CASE PRESENTATION A 26-year-old pregnant woman complained lower abdominal distension. Ultrasound imaging showed a solid tumor in the right adexna and massive ascites. The blood test showed elevated serum level o...
The treatment of infertility in polycystic ovary syndrome (PCOS) associates lifestyle measures, and the use of drugs to induce ovulation. In this endeavour, clomifene citrate (CC) should be used as the first line of treatment, followed eventually by low dose gonadotrophin stimulation, as a second line. In rare cases, in case of failure of the CC treatment, ovarian drilling i.e. laparoscopic ova...
A report of a high incidence of genetic abnormality after in vitro fertilisation' led to a suggestion that the apparently low fecundity in man' may be partly explained by a high incidence of loss of embryos due to genetic factors. Data from induction of ovulation in patients with hypogonadotrophic hypogonadism, however, suggest that a high incidence of conception may be achieved.3 Advances in u...
PURPOSE Heparan sulfate proteoglycans have been implicated in cancer cell growth, invasion, metastasis, and angiogenesis. This study was designed to compare their expression in normal ovary and ovarian tumors and then to examine their prognostic significance in ovarian cancer. EXPERIMENTAL DESIGN The expression of syndecan-1, -2, -3, and -4, glypican-1, and perlecan was assessed by immunohist...
Epithelial ovarian carcinomas are successfully treated but seldom cured with standard platinum-based chemotherapy regimens. Investigation continues on the role of high-dose chemotherapy as part of salvage, consolidation and primary induction treatment strategies. Currently, the majority of available clinical studies suggest that modest increases in the dose of platinum in primary induction ther...
