OBJECTIVE In ovarian cancer, detection of sentinel nodes is an upcoming procedure. Perioperative determination of the patient's sentinel node(s) might prevent a radical lymphadenectomy and associated morbidity. It is essential to understand the lymphatic drainage pathways of the ovaries, which are surprisingly up till now poorly investigated, to predict the anatomical regions where sentinel nod...

The aim of this study was to investigate whether unilateral, intraovarian infusions of bacteria might have induced morphological changes in the contralateral ovary. Eleven sexually matured gilts with controlled estrous cycle were used. The animals were randomly divided into two groups: I (Gr. I, treated; n = 4), and II (Gr. II, control; n = 7). In Gr. I, 1 ml of bacterial suspension (10(3) colo...

AIM To investigate the expression and distribution of HBV in the ovaries and ova. METHODS The immunohistochemistry method was used to detect the HBsAg and HBcAg in the ovaries of patients with chronic hepatitis B. RESULTS Expression of HBsAg in the ova, granular and interstitial cells of the ovaries was located in the cytomembrane and cytoplasm. Expression of HBcAg in the ova, granular, int...

These experiments were performed to test the perfusion of ovine as a model for human ovaries by cryoprotectants in vivo at high temperature when the permeability of capillaries is high and when blood is insensibly replaced by the solution of cryoprotectants. By our hypothetical supposition, ovaries could be saturated by cryoprotectants before their surgical removal. The objective was to examine...

During the breeding season extending from spring to summer, the ovaries of the fish, Oryzias latipes, contain hundreds of follicles, each with an egg at various stages of maturation. Usually, five to fifty eggs are laid by a single female almost every morning(Egami, 1954c). On the other hand, ovaries are small and inactive in winter months. The present author has already reported that small win...

ABSTRACT Squamous metaplasia of the rete ovarii is an ovarian pathologic change characterized by replacement normal single layered cuboidal epithelium a stratified squamous keratinized epithelium. Uterus and ovaries from local slaughterhouse pregnant crossbreed cow were evaluated through ultrasound, macroscopically histologically. Grossly, there multiple cysts in both ovaries, which histologica...

Pieces of ovaries and tumors from 45 patients (19 with malignant epithelial tumors, 14 with benign epithelial tumors, and 12 with normal postmenopausal ovaries) were incubated, and the release of steroid hormones from different parts of the tumors and from the contralateral ovaries was measured. Tumor tissue (mainly tumor cells with a small number of stromal cells), tumor base tissue (more stro...

OBJECTIVES The aim of this study was to investigate the effects of static magnetic field (SMF) during transplantation of the ovarian tissue into the testis. MATERIALS AND METHODS In this experimental study, ovaries of 6- to 8-week-old female Naval Medical Research Institute (NMRI) mice were randomly divided into four groups: i. Fresh ovaries were immediately transplanted into the testicular t...

BACKGROUND It has been reported that calf oocytes are less developmentally competent than oocytes obtained from adult cows. Bone morphogenetic protein 15 (BMP15) and growth and differentiation factor 9 (GDF9) play critical roles in folliculogenesis, follicular development and ovulation in mammalian ovaries. In the present study, we attempted to compare the expression patterns of BMP15 and GDF9 ...
