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....

Uterine torsion is a twisting of the uterus or uterine horn perpendicular to its long axis. We report a case of uterine torsion in an adult breeding Sprague Dawley rat. The rat died a month after her last recorded delivery. Post mortem examination of the rat revealed 270 degrees torsion of the right uterine horn. The uterus contained a single foetus. The liver was pale and enlarged. The rest of...

Many species exhibiting hemochorial placentation experience an accumulation of macrophages in the endometrium during pregnancy. For the present study, it was tested whether macrophages also accumulate in the endometrium of the sheep, which is a species undergoing an epitheliochorial placentation. An additional objective was to determine whether regulation of endometrial macrophage number occurs...

Uterine natural killer (uNK) cells, a specific type of (NK) are important cells at the foeto-maternal interface in humans as well mice. uNK part innate lymphoid group 1. Especially mouse, but also rat, many vivo studies have been performed to evaluate role placental development. These shown that not indispensable pregnancy, they play an optimal decidual angiogenesis early trophoblast invasion a...

1. Marked specific contractions of the uterine horns of guinea pigs, actively sensitized, to phage-lysed Flexner bacilli or to colon bacilli, lysed by the same bacteriophage, occurred on testing either series for anaphylaxis with the homologous phage lysates. These reactions, however, were not due to an antigenic function of the bacteriophage itself, because no reaction whatsoever occurred when...

The objective of this study was to evaluate, using an embryo donation model, whether impaired oocyte/embryo developmental competence and/or changes in uterine milieu are responsible for the previously observed adverse effects of superovulation with gonadotrophins on implantation and fetal development in mice. Embryos from superovulated and non-stimulated females were transferred to separate ute...

The antiluteolytic effect of prostaglandin (PG) E2 was tested in two experiments. In experiment I, seven nonpregnant ewes that had ovulated bilaterally, were laparotomized on day-11 postestrus. Uterine horns were isolated by ligatures between the internal and external bifurcations and around blood vessels in the intercornual area. An Alzet TM minipump (25 • 6.5 ram) containing PGE2 (delivery ra...
