OBJECTIVE To study the pharmacodynamic and pharmacokinetic properties of oral and intravenous methylergometrine upon uterine motility during menstruation. STUDY-DESIGN Intra-uterine pressure was measured in six volunteers with a fluid-filled sponge-tipped catheter during menstruation. Methylergometrine was given orally (0.5 mg) or intravenously (0.2 mg) in a cross-over design. RESULTS After...

Restriction of the conceptus to one uterine horn of the pregnant ewe results in the accumulation of fluid called uterine milk (UTM) in the contralateral horn. Two basic polypeptides, called the uterine milk proteins (UTM-proteins; Mr = 55,000 and 57,000 as determined by polyacrylamide-gel electrophoresis using sodium dodecyl sulfate), accounted for the majority of the protein in uterine milk. T...

background: abnormal uterine bleeding is a common presentation of uterine abnormalities among premenopausal and postmenopausal women. objective: to evaluate and compare the diagnostic accuracy of saline contrast sonohysterography and hysteroscopy for detecting the cause of abnormal uterine bleeding. materials and methods: a total of 65 women with abnormal uterine bleeding were enrolled in this ...

Hysteroscopy is a minimally invasive procedure that may result in potentially disastrous complications. A hysteroscopy requires the insertion of a hysteroscope into the uterine cavity and the installation of a suitable distention medium for visualization of the endometrium. Potential risks include fluid volume overload, uterine perforation, hemorrhage, infection, and the need for immediate hyst...

During a research visit for tissue collection at an abattoir located in Pelotas, Brazil, one female genital tract showed both enlarged oviducts. The reproductive tract was collected and analyzed. Occluded uterine tubes and an increase in the organ volume due to the large amount of fluid in the organ lumen were the macroscopic findings. Three samples, corresponding to isthmus, ampulla and infund...

OBJECTIVE To compare the Koala air-charged coupled catheter (Clinical Innovations, Inc., Murray, Utah) for monitoring intrauterine pressure (IUP) during active labor with an electronic pressure transducer-tip catheter, Intran Plus (Utah Medical Products, Midvale, Utah). STUDY DESIGN Simultaneous recordings with Koala and Intran catheters bound together at their tips were made in 18 term patie...

The acid-base status of late-term Squalus acanthias L. pups in the uterine seawater environment was examined. Blood values for pH, total CO2, partial pressure of CO2, urea and sodium concentrations in late-term pups were not significantly different from those of the mothers. Haematocrit was slightly lower, while total plasma lipid and ammonia concentrations were several times higher. The uterin...

Before implantation into the uterine wall, the mammalian embryo undergoes a period of cell division, cell shape change, and cell differentiation leading to the formation of an outer epithelium, the trophectoderm. The trophectoderm is the part of the embryo that initiates uterine contact and, after transformation to become the trophoblast, uterine invasion. Similar to the kidney nephron, the tro...

A twisting or rolling of the uterus along its longitudinal axis is known as uterine torsion (Roberts, 2004). Compared to other domestic animal species, bovines have a significantly higher prevalence dystocia (Dutt et al., 2021). Uterine one common causes in buffaloes than cows (Purohit 2011). In dairy cattle frequency right horn pregnancy reported 60% 68%, counterclockwise would then be detecte...
