Hysteroscopic complications are infrequent. Major complications include: 1. Uterine perforation that is the most common complication of operative hysteroscopy (0.8 - 1.6 %). The perforation rate is less during diagnostic hysteroscopy. 2. Bowel or bladder injury which is rare, but may occur in association with uterine perforation or as a result of use of electrical current. 3. Cervical laceratio...

Ritodrine hydrochloride concentrations were measured by radioimmunoassay in maternal and fetal sera and amniotic fluid from eight, pregnant, volunteers. Each patient agreed to have 420 micrograms . kg-1 of ritodrine infused intra-venously over two hours prior to elective cesarian section. During infusion a blood sample was taken every 30 minutes from a maternal peripheral vein. Once anesthesia ...

The presence of more than 2 cm (height) of uterine fluid during estrus seems to be a predictor of susceptibility to postbreeding endometritis.

BACKGROUND Apoptosis, a process of normal embryonic development, is enhanced in blastocyst from diabetic rats. Nevertheless, glucose seems not to be the only factor involved. Activin A, a TGF-beta family member, is also increased in maternal serum from diabetic pregnancy. METHODS Flushing medium, blastocysts and uterine cells were obtained from 5 day old pregnant rats. The presence of activin...

The role of avian eggshell matrix proteins in shell formation is poorly understood. This calcitic biomaterial forms in a uterine fluid where the protein composition varies during the initial, calcification, and terminal phases of eggshell deposition. A specific antibody was raised to a 116-kDa protein, which is most abundant in uterine fluid during active eggshell calcification. This antiserum ...

Spontaneous uterine rupture is lethal in pregnant women. Placenta percreta-induced spontaneous uterine rupture in the first trimester is extremely rare and difficult to diagnose. A 35-year-old pregnant woman, with a history of 2 vaginal deliveries and 2 spontaneous abortions treated by dilatation and curettage, was admitted to the emergency department because of sudden severe abdominal pain; th...

Chicken eggshell is the protective barrier of the egg. It is a biomineral composed of 95% calcium carbonate on calcitic form and 3.5% organic matrix proteins. Mineralization process occurs in uterus into the uterine fluid. This acellular fluid contains ions and organic matrix proteins precursors which are interacting with the mineral phase and control crystal growth, eggshell structure and mech...

Soluble proteins were studied in the developing rabbit blastocyst by using a micro-disc electrophoresis technique. The tissues of the blastocyst (in later stages separated into the embryoblastic and trophoblastic parts) were analysed, and their protein patterns were compared with those of uterine secretion and blastocyst fluid. A protein pattern with more than 20 protein fractions was found in ...

UNLABELLED Under progesterone (P) dominance, fluid loss assists uterine closure which is associated with pH reduction. We hypothesize that P inhibits uterine fluid secretion and HCO3⁻ transport. AIM To investigate the expression of Cystic Fibrosis Transmembrane Regulator (CFTR) and Cl⁻/HCO3⁻ exchanger (SLC26A6) under P effect. METHOD Uteri from ovariectomized steroid replaced and intact rat...
