    Membranas embrionárias e fetais de equinos sob análise de microscopia eletrônica de transmissão
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2009-09-30) NASCIMENTO, Priscila Leal do; MANÇANARES, Celina Almeida Furlanetto; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; FRANCIOLLI, André Luis Rezende; FERRAZ, Ana Cláudia Cristiane; MANÇANARES, Ana Carolina Furlanetto; CARVALHO, Ana Flávia de
    To develop this research, 16 pregnant uteri were used, of which 16 placentas were obtained divided into groups of different stages of development. The material was collected from adult, mixed breed mares up to 100 days of gestation. The membranes were intended for ultra-structural analysis and the results obtained under transmission electron microscopy (MET) were similar to those found by ASSIS-NETO (2005), in bovine membranes, and ITURRIZAGA (2005), in llamas. The fetal membranes did not show relevant structural differences in the different periods studied. The chorion showed columnar epithelium; mesenchymal tissue rich in collagen fibers, the trophoblastic cells being uni, binucleated and rarely trinucleated. A large number of mitochondria were present mainly at the apex of cells. The allantoic presented a simple columnar epithelium with globular nuclei and a large concentration of mitochondria at the cell apex, in the cell base there was a large amount of rough endoplasmic reticulum. The amnion showed a simple, squamous epithelium and at the cellular apex there was a large amount of electrondense granules covered by a rounded halo. The yolk sac epithelium varied from globose to columnar, with uni or binucleate cells in a single layer, with a large amount of rough endoplasmic reticulum, uniformly distributed. Between the endodermal cells, intercellular spaces were found. So far, it is concluded that the mare's placenta is choroidal alloid, epithelial, diffuse, non-deciduous and villous, with corium cells and a yolk sac with characteristics of protein secretion, while amnion presented secretion vesicles, but with less amount of rough endoplasmic reticulum.

    Classificação macroscópica dos dentes de Nasua nasua
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2009-09-30) PIREI, Naira Caroline Godoy; MANÇANARES, Celina Almeida Furlanetto; ROSA, Ricardo Alexandre; CARVALHO, Ana Flávia de; BERTASSOLI, Bruno M.
    Nasua nasua, also known as coati, is an omnivorous mammal, with wide distribution throughout South America, found from Colombia to Argentina and in Brazil it occupies all regions. The evolution caused in the teeth of mammals multiple variations, adapting the most diverse diets. Due to these variations, it is possible to classify vertebrates by order, gender and family. This work aimed to morphologically classify the teeth of males and females Nasua nausa, in order to classify and compare them with each other and with the morphology of Cannis familiaris (dogs) teeth described in the literature. In this study, five heads of Nasua nasua were used, adults, of both sexes, provided by the scientific breeding CECRIMPAS (UNIFEOB). Two macerated animals had their oral cavity exposed for the photographic documentation of the position of the teeth. In the oral cavity of Nasua nasua due to sexual dimorphism, it was possible to compare the male and female dentition macroscopically. The female has smaller teeth, rounded canines, and the incisor group on the lower part is smaller than on the upper and in the male they are pointed and larger. The animals presented 2x dental formula (I3 / 3, C1 / 1, P4 / 4, M2 / 2), with I = incisors, C = canines, P = premolars and M = molars, in a total of 40 teeth.
