    Análise ultra estrutural das membranas embrionárias e fetais de equinos
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2008-11-30) NASCIMENTO, Priscila Leal do; MANÇANARES, Celina Almeida Furlanetto; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; CARVALHO, Ana Flávia de
    To develop this research, 13 pregnant uteri were used, of which 13 placentas were obtained divided into groups at different stages of development. The material was taken from adult, mixed breed mares and at different gestation periods of up to 120 days and was destined for ultrastructural analysis. The results obtained from SEM (scanning electron microscopy) were similar to those found by ASSIS-NETO (2005), in bovine membranes. The allantoic showed cells whose surface was bordered by microvilli, forming polyhedral images, protruding “button” shaped structures were also observed. At the amnion, a surface similar to that of the allantois was observed, with its entire length covered by microvilli. In the corium, the apical surface of the cells are rounded and covered by microvilli. The yolk sac showed droplets of secretion at the apex of the cells indicating exocytosis. So far it has been concluded that the mare's placenta is chorioallantoic, epithelial, diffuse, non-deciduous and villous.

    Análise biométrica de embriões, fetos e das membranas placentárias de equinos.
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2008-11-30) FERRAZ, Ana Cláudia Cristiane; MANÇANARES, Celina Almeida Furlanetto; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; CARVALHO, Ana Flávia de
    For this study, embryos, fetuses and attached membranes of 23 concepts of mares from Frigorífico Miramar - Pelotas RS were used. Embryos and fetuses were analyzed for size and external developmental characteristics to analyze gestational age. The attached membranes were weighed and measured for later correlation with gestational ages. The results obtained so far indicate that the embryonic and fetal development of horses is very fast in the early stages of development, this being a critical period of placental implantation and the beginning of the endocrine activities of the placenta. The biometric data related to the umbilical cord are not progressive according to development, having shown great variations among the animals studied.

    Achado histopatológico de lipidose hepática em fetos de gambá (Didelphis sp.) lactantes
    (Fundação de Ensino Octávio Bastos, 2008-11-30) GARCIA, Fernanda Figueiredo; MANÇANARES, Celina Almeida Furlanetto; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; ROSA, Ricardo Alexandre; CARVALHO, Ana Flávia de
    Opossums (Didelphis sp.) Are highly reproducible marsupials, have a gestation period of approximately 12 days and extensive lactation. Fetuses receive high levels of carbohydrates and lipids from the mother during lactation. The objective of this work was describe the macro and microscopic morphology of the livers of opossum fetuses (Didelphis sp.) at different stages of their postnatal development. An old animal (5 days, 15 days, 22 days and 35 days) for macroscopic and microscopic verification of liver structures and consequent comparison with other domestic species. The animals' livers were processed and included by paraffin embedding techniques. Each block was cut and the sections were stained with HE, picrosirius, PAS histochemical reaction with hematoxylin, toluidine blue and Masson's trichrome to observe the hepatic structures. The macro and microscopic results indicate a premature development of the species in the fetal stage, similar to domestic animals and interestingly there is presence of hepatic lipidosis in all animals.
