Superoxide dismutase (SOD) activity in flushings from oviducts and uterine horns of 8 anestrous, 5 estrous and 7 diestrous bitches was measured. SOD activity in oviductal fluid in estrous bitches was significantly higher than that in anestrous and diestrous bitches (P<0.01). SOD activity in uterine fluid of diestrous bitches was, however, significantly higher than that in anestrous and estrous ...

The eggshell of the hen is a highly ordered and mineralised structure, which is sequentially deposited within an acellular milieu – the uterine fluid secreted by the distal oviduct. Spherulitic crystal growth of calcite is initiated on organic aggregates on surface of the eggshell membranes, followed by competition between radial crystallites for space to form a compact columnar biomineral. The...

Background Earlier it was believed that uterine fluid (UF) or secretions are not relevant after the embryo implantation in humans. However, recent reports suggest that uterine secretions continue to play important role till the first trimester of human pregnancy. Evidences also suggest that uf mirrors endometrial functions or dysfunctions. Considering the relevance of uf in endometrial function...

Uterine glands are essential for pregnancy in mice and likely humans, because they secrete or transport bioactive substances that regulate uterine receptivity for blastocyst implantation. In mice, the uterus becomes receptive to blastocyst implantation on day 4, but is refractory by day 5. Here, blastocysts could be recovered from progesterone-induced uterine gland (PUGKO) but not wildtype (WT)...

Administration of the phytoestrogen coumestrol to ovariectomized rats leads to increases in both wet and dry uterine weights in the absence of an increase in uterine DNA content, as reported by Markaverich et al. [Effects of Coumestrol on Estrogen Receptor Function and Uterine Growth in Ovariectomized Rats. Environ Health Perspect 103:574-581 (1995)]. It was not possible to know if the observed...

UNLABELLED Uterine rupture is a rare life-threatening complication. It mainly occurs in the third trimester of pregnancy and is rarely seen during the first or second trimesters. Our centre experienced three important cases of uterine rupture. FIRST CASE spontaneous uterine rupture at 14 weeks of pregnancy, which was diagnosed at autopsy. It was misled by the ultrasound finding of an intraute...

Amino acid arylamidase I (in earlier work also referred to as leucine aminop~ptidase) appears in the uterine epithelium and is extruded into the uterine lumen in considerable quantities after 3 d p.c. (days post coitum) in the rabbit. In the uterine secretion, the activity of this enzyme shows a very sharp and high peak at 5 d p.c., i .e. in the middle of the preimplantation phase, and it decli...

INTRODUCTION Uterine rupture is a life-threatening condition both to mothers and fetuses. Its early diagnosis and treatment may save their lives. Previous myomectomy is a high risk factor for uterine rupture. Intestinal adhesion due to previous myomectomy may also prevent early diagnosis of uterine rupture. CASE PRESENTATION A 38-year-old primiparous non-laboring Japanese woman with a history...

Rupture of gravid uterus is surgical emergency causing maternal and fetal morbidity and mortality. The risk of uterine rupture is associated with uterine scars caused by previous cesarean section, myomectomy, hysteroscopic procedures, and curettage. We report a case of a 40-year-old woman in 31st week of gestation with spontaneous uterine rupture. It was her third pregnancy. She had two healthy...
