During rat estrous cycle, the endometrium proliferates in response to sex steroids and specific endometrial epithelial cells undergo apoptosis in absence of embryonic factors. The central executioner of apoptosis is a family of aspartic acid-specific cysteine proteases known as caspases. Smac/DIABLO is released from the mitochondria during apoptosis and its stimulation promotes caspases activat...

BACKGROUND To test the feasibility of photodynamic therapy (PDT)-based ablation of rat embryos as a model for PDT of extrauterine pregnancy (EUP) in humans. METHODS A controlled pre-clinical study. Selected rat embryos [one per litter, n = 30, embryonic day 14 (E14)] were subjected to placental injection of a Palladium-bacteriochlorophyll derivative and illuminated to achieve selective photo-...

We investigated the binding characteristics, content and intracellular distribution of nuclear and cytosolic oestrogen receptors in the uteri of rats bearing a unilateral intrauterine device, fitted 14--18 days earlier, at four phases of a 5-day oestrous cycle. The patterns of changes in wet weight and content of cytosolic and nuclear receptor that normally occur during the oestrous cycle were ...

Offspring of women exposed to opiate drugs such as heroin and methadone during pregnancy have a high incidence of morbidity and mortality. Infants also show opiate withdrawal. In this study, we examined the behavioral effects of precipitated withdrawal in morphine-dependent fetal rats at gestational day (GD) 20. The dam was implanted on GD 14 with a pellet containing 75.0 mg of morphine. On GD ...

PURPOSE To investigate the effects of remifentanil as an antioxidant and analyze the histopathologic, biochemical changes in experimental ischemia-reperfusion (I/R) exposed rat uteri. METHODS Wistar albino rats were assigned to three groups (n = 7). 2h period of ischemia was followed by 1h of reperfusion in the I/R and the I/R-remifentanil groups. After ischemia, no drug was administered in t...

On necropsy of a 24 months age Dutch female rabbit the uterine horns seems enlarged with a nodular appearance. On the cut surface of the uterus as well as heart wall, white firm masses with a cauliflower- like surface was observed. No other important gross lesions were found in other organs. In histopathological examination of the uterus typical microscopic changes were those of adenocarcinoma....

Four estrous beagles were inseminated with 1 x 10(8) sperm into both the right and left uterine horns, and the uterine horn and oviduct on one side were removed under anesthesia after 7 hr and 24 hr, respectively. The lumen of the uterine horns and oviducts was flushed with canine capacitation medium (CCM), and movement of the sperm in CCM was assessed by phase-contrast microscopy. In a second ...

Uterine lymphatics were examined in 38 pigs using light microscopy, stereomicroscopy, and scanning electron microscopy. Uterine lymphatics were initially filled with plastic materials: Microfil for stereomicroscopy, Mercox-corrosion cast for scanning electron microscopy (SEM), and Micropaque for x-ray photographs. Lymph precollectors of the uterine horns formed two superficial layers, ventral a...

Bicornuate uterus has two symmetric uterine cavities that are fused caudally and have some degree of communication between two cavities, usually at the uterine isthmus. A complete bicornuate uterus has a seperatory cleft of tissue that is extended to the internal OS. Lesser degree of septation of the two uterine horns has constitution, a partial bicornuate uterus. Bicornuate uterus is a class o...
