25. Avaliação da espressão de glicoproteinas potencialmente especificas na membrana plasmatica de celulas Natural Killer uterinas de camundogos / Evaluation of expression of potentially specific glycoproteins in plasmatic membrane of mouse uterine Natural Killer
The phenomenon of pregnancy in mammalians with hemochorial type placenta ions where the allogeneic fetus presenting the half of gene from paternal origins growth in tight contact with maternal tissues, without triggering the rejections responses of maternal immune system is still a non-solved question of immunology of reproduction. The cross-talk at maternal

26. A subplacenta da paca (Agouti paca, Linnaeus 1766) / The subplacenta of the paca (Agouti paca, Linnaeus 1766)
The rodents of suborder hystricomorph, in which is classified the Agouti paca, present hemochorial type placentation and develops an unique structure known as subplacenta. In spite of many report of its presence in several species, the possible functions of this structure related to placenta and pregnancy remains speculative, mainly due to the diversity of f

27. Microestructural, histochemistry, and inmunohistochemistry study of the llama´s placenta (Lama guanicoe glama) / Estudo micro-estrutural, histoquímico e imunoistoquímico da placenta de lhama (Lama guanicoe glama)
The placenta of the llama has been described like epitheliochorial, but existent researches dont study in depth microscopic aspects. In order to detail their ultrastructurals characteristics observations were made by light microscopy and scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Samples of nine uteruses between 28 to 36 w

28. Development placental in bovines obtained by natural gestation and by in vitro fertilization / Desenvolvimento placentário em bovinos obtidos por gestações naturais e por fecundação in vitro
The main goal of this study was to describe morphology and the early gestational development of 15 to 70 day-old bovine embryos obtained by natural mating and 35 day-old bovine embryos obtained by in vitro fertilization (IFV) technique. One hundred and forty-one concepts originated by natural mating and seven by IVF technique were used. All concepts were dis

29. À procura do Ped bovino / Searching for the Ped gene
The aim of the present work was to identify bovine MHC class I genes similar to the murine Ped gene expressing during embryonic development and pregnancy. Bovine in vitro produced embryos and placentas obtained from natural mating or cloning-derived fetuses had their RNA extracted. cDNA was synthesized to isolate fragments showing similarity with the gene de

30. Estudo imunoistoquimico do infiltrado inflamatorio em vilosite de etiologia desconhecida, vilosites causadas por parasitas e intervilosite fungica : estudo comparativo com analise qualitativa e quantitativa
Villitis is characterized by an inflammatory infiltrate within the villous stroma and can be caused by a large number of infectious agents, although most are of unknown etiology. Villitis, not rarely, is associated with intrauterine fetal death, abortion, malformations and fetal growth retardation. The latter has been the major clinical association of villit

31. Amino acid composition of parturient plasma, the intervillous space of the placenta and the umbilical vein of term newborn infants
The objective of the present study was to determine the levels of amino acids in maternal plasma, placental intervillous space and fetal umbilical vein in order to identify the similarities and differences in amino acid levels in these compartments of 15 term newborns from normal pregnancies and deliveries. All amino acids, except tryptophan, were present in

32. Expression and distribution of Connexin-43 in bovine trophoblast giant cells in three gestational phases / Expressão e distribuição da conexina 43 nas células trofoblásticas gigantes bovinas em três fases gestacionais
O presente trabalho estudou a expressão da conexina 43 nas células trofoblásticas gigantes bovinas, em especial nas células trofoblásticas gigantes binucleadas. Foram utilizadas 12 amostras de placenta bovina, divididas em três grupos segundo a fase gestacional, primeiro terço, segundo terço e terceiro terço da gestação. O tecido placentário foi

33. Placentation in rock cavies, Kerodon rupestris (Wied, 1820) / Placentação em mocós, Kerodon rupestris Wied, 1820
Placentation studies of fourteen rock cavy females in different gestation phases were conducted. Females were pre-anesthetized associating ketamine chloridrate (15mg/kg) and midazolan (1mg/kg). Soon afterwards, they were anesthetized by isoflurane inhalation in association with oxygen at 100% saturation. After anesthesia, the surgery allowed to exhibit fetal

34. Placental erytrophagocytosis in water buffalo (Bubalus bubalis bubalis - Simpson, 1945) / Eritrofagocitose placentária em búfalas (Bubalus bubalis bubalis - Simpson, 1945)
A função da eritrofagocitose observada após o extravasamento de sangue na interface materno-fetal é indefinida em várias espécies, incluindo o búfalo. Na ovelha, este processo foi muito estudado, e ocorre na zona arcada do placentônio (topos dos septos maternos e base dos vilos fetais), região onde o processo é realizado pelo trofoblasto. É possí

35. Estudo Macro e Microscópico da Placenta de Termo de Capivara (Hydrochaeris hydrochaeris - Carleton, M. D. 1984) / Macroscopic and microscopic study of mature capybara placenta (Hydrochaeris hydrochaeris - CARLETON, M. D. 1984)
South and Central America are the natural habitat of the capybara, in the areas that go from Panama to Argentina, including the Andes region. These animals are herbivorous, diurnal, semi-aquatic, gregarious and docile; they live in large groups and are potentially important for the production of high quality meat, skin and oils, largely utilized in popular m

36. Development of the placenton in water buffalo (Bubalus bubalis bubalis Linnaeus, 1758) / Desenvolvimento do placentônio em búfalos (Bubalus bubalis bubalisLinnaeus, 1758)
The ruminant placenta has an uniform gross structure based on specialized areas of feto-maternal membrane apposition and proliferation: the placentons. By exerting a fundamental role for the development of the pregnancy, these structures have been very well studied in several domestic species of commercial interest. Particularly in the buffalo, however, ther
