1. Immunohistochemical localization of progesterone receptors alpha (PRA) in ovary of the pseudopregnant rabbit
Abstract Progesterone plays an important role in the reproductive function and follicular development in mammals. The aim of the present study was to examine the localization of progesterone receptor alpha (PRA) in ovary of pseudopregnant rabbit by immunohistochemical methods. Samples were collected from 14 h. to 18 days of pseudopregnancy. At the first stag

2. Analysis of the effect of aminiotic fluid on uNK cells in the mice pseudopregnant uterus / Análise do efeito do líquido amniótico nas células uNK do útero pseudogestante de camundongos
As células Natural Killer uterinas (uNK) participam da interação materno fetal atuando ativamente como elemento imuno-modulador do micro-ambiente uterino na gestação bem sucedida. Apesar das uNK possuírem um potencial lítico, relacionado com a sua resposta imune inata, este não se manifesta em uma gestação normal. Por outro lado, diversos relatos s

3. O modelo de pseudogestação em camundongos para o estudo in situ das celulas Natural Killer uterinas / The pseudopregnancy model in mice for the in situ study of the uterine Natural Killer cells
Durante o período peri-implantacional na gestação de humanos e roedores, ocorre no estroma da mucosa uterina um conjunto de fenômenos que envolvem modificações dos componentes celulares e da matriz extracelular. Este conjunto de modificações é conhecido como decidualização ou reação decidual. Concomitante a este processo ocorre a migração de l

4. The effect of pseudopregnancy on glomerular filtration rate and salt and water reabsorption in the rat.
1. Glomerular filtration rate (G.F.R.) and salt and water reabsorption were measured in age-matched virgin rats and rats at different stages of pseudopregnancy and post-pseudopregnancy. 2. Tubular reabsorption and G.F.R. were significantly higher in later pseudopregnancy. Values at mid-pseudopregnancy were intermediate between virgin controls and late-pseudo

5. Myometrial activity in rats during the oestrous cycle and pseudopregnancy: interaction of oestradiol and progesterone.
1. Oestradiol 17 beta inhibits the rat myometrium but the role of progesterone is uncertain. We have examined the interaction of the two steroids in the control of uterine activity in pseudopregnancy and the oestrous cycle. 2. Progesterone reversed the oestradiol-induced inhibition of the myometrium in ovariectomized rats in vivo, but had little inhibitory e

7. Morphometric evidence of changes in the vasculature of the uterine tube of mice induced by the 2-cell embryo on the second day of pregnancy.
Some evidence suggests that the uterine tube plays an active role in supporting the development of the preimplantation embryo. To determine whether there were morphological and/or ultrastructural changes in the uterine tube as a consequence of pregnancy, the region of the uterine tube containing 2-cell embryos or oocytes was examined in untreated d 2 pregnan

8. Lymphoid response to pregnancy and pseudopregnancy in the rat.
Differences in weight, while cell density and differential white cell count of the thymus, spleen, iliac and popliteal lymph nodes of virgin, 10 days outbred pregnant, 10 days inbred pregnant, 10 days pseudopregnant, and 40 days outbred post-coitum rat were examined. Compared with virgin animals, significant weight gain occurred only in the thymus, spleen an

9. Metrial gland cells in deciduomata of pseudopregnancy.
Light and electron microscope studies were carried out on the metrial gland cells of deciduomata of pseudopregnancy in the rat. At the light microscope level these cells were characterised by a comparatively pale staining cytoplasm with numerous glycoprotein granules. Some also had extensive cytoplasmic deposits of glycogen. In electron micrographs the metri

10. Oestrogen and the differentiation of granulated metrial gland cells in chimeric mice.
The role of oestrogen in the recruitment of GMG cell precursors to the uterus has been investigated in radiation-induced chimeric mice reconstituted with rat bone marrow and maintained on a hormone regime simulating pseudopregnancy. The presence of rat GMG cells in the deciduomata in mice irradiated after oestrogen priming suggests that oestrogen priming is

11. Granulated metrial gland cells in the lungs of mice in pregnancy and pseudopregnancy.
A study has been made, using light microscopy, of GMG cells in the lungs of pregnant mice and pseudopregnant mice with deciduomata. GMG cells are found in the lungs from Day 8 to Day 17 of pregnancy and are mainly located in the interalveolar septa. The temporal relationship between GMG cells in the lungs and GMG cells in the blood vessels of the decidua bas

12. Effect of the estrous cycle on uterine infection induced by Escherichia coli.
Escherichia coli was inoculated into the uterine lumen of rats and rabbits at different estrous stages; one uterine horn of each animal was ligated at the cervical end. In rats, a large number of E. coli were retained in the ligated horns regardless of the estrous stage. E. coli inoculated at diestrus or pseudopregnancy induced purulent endometritis, but whe
