Caracterização macroscópica do funículo umbilical de búfalos
(Centro Universitário da Fundação de Ensino Octávio Bastos, 2001-11-30) FERREIRA, Guilherme J. B.C.; CARVALHO, Ana Flávia de; AMBRÓSIO, Carlos Eduardo; MIGLINO, Maria A.; ROSA, Ricardo Alexandre; ESTEVES, Alessandra; THOMAZ, Juliana M.
The umbilical funiculus is the organ that connects the fetus to the placenta where blood and excreta from the fetus pass. Arterial blood flows from the placenta to the fetus through the umbilical veins and venous blood through the arteries, the excretion is carried through the allantoic duct. In this study, nine fetuses were used, which had their funicles measured and dissected, in order to establish developmental correlations and describe their morphology. The funnel was rod-shaped, a parallel arrangement of the vessels in the fetal just portion and a standard ruminant arrangement in the just portion - placental and middle.
Ectoparasitas ou quirópteras em três regiões serranas do sudeste brasileiro

The research aimed to study ectoparasites in bats in three mountain areas in Southeast Brazil. (Serra da Fartura, Serra de Itatiaia, Serra da Bocaina), where 130 hosts were captured with '' nets '' nets which had 48 ectoparasites from the Nycterebilidae, Strebilidae, Spinturnicidae, Polytenidae and Tuncicidae families. Chiropterans have very distinct ectoparasites that range from mites, Diptera, Hemiptera to fleas, so a further study of the relationship of these ectoparasites with other types of hosts should be performed.
Estudo da morfologia e vascularização do rim de avestruz
(Fundação de Ensino Octávio Bastos, 2001-11-30) MARTINS, Daniele dos Santos; AMBRÓSIO, Carlos Eduardo; MIGLINO, Maria Angélica; FINAZZI JÚNIOR, Renato; FERREIRA, Guilherme J. B.C.; BARREIRO, Rodrigo H.
The main objective of this work is to describe the morphology and vascularization of the ostrich kidney, making it possible to compare it with the domestic rooster, duck and goose kidney with that bird. The morphological study shows that these kidneys have a cranial lobe, a middle lobe and a caudal lobe. sciatic artery. The venous system corresponds to the renal portal system, which presents two amastomoses, in the ventral view; one occurs at the interposition of the middle lobe with the caudal lobe, and another located in the cranial lobe; the veins that drain the lobes are: cranial renal vein, middle renal vein and caudal renal vein.
Estudos macro e microscópicos da glândula pineal de Kerodon rupestris
(Fundação de Ensino Octávio Bastos, 2001-11-30) THOMAZ, Juliana M.; CARVALHO, Ana Flávia de; MIGLINO, Maria Angélica; ESTEVES, Alessandra; FERREIRA, Guilherme J. B.C.
The pineal gland, in some mammals, is considered a complex instead of a single organ, being responsible for secreting melatonin, a hormone that triggers the puberty awakening and controls circadian cycles. Macroscopically, we obtained a pineal gland darker than the brain, in the form of a rod, extending from the habenular commissure to the dura mater and located between the rostral colicles, in the median portion of the brain. Histologically, it was similar to other rodents, with pinealocytes, secretory cells, glial support cells and limestone concretions.
Morfologia da placenta canina
(Fundação de Ensino Octávio Bastos, 2001-11-30) AMBRÓSIO, Carlos Eduardo; MIGLINO, Maria Angélica; FERREIRA, Guilherme J. B.C.; CARVALHO, Ana Flávia de; ROSA, Ricardo Alexandre
The placenta of SRD dogs was studied through macro, microscopic anatomy and scanning electron microscopy, analyzing the maternal and fetal vascular systems. It was classified as complete annular zonary, endothelial and lamellar with marginal hematomas in the extension of the margins of the placental brace. The vascularization of the organ is carried out by funicular vessels, branches, central placental and other, chorionic placental. Ventrally to the fetus, the remnant of the highly vascularized yolk sac is evident, characterizing the ventral choriovitheline placenta. Marginal hematomas were considered blood lakes arranged in contact with the trophoblast giving blood leakage originating from the maternal vessels, determining erythrophagositis and iron endocytosis. Placental microvascularization determines the lamellar classification of the canine placenta. At the fetal maternal interface, there are fetal capillaries arranged in a basket shape and maternal capillaries in the form of '' tufts of hair '' interspersed with gaps
Relato de caso de teratologia em avestruz
(Fundação de Ensino Octávio Bastos, 2001-11-30) OLIVIERI, Daniela Liliane; MELLO, Eduardo Castanheira de; FERREIRA, Guilherme J. B.C.; CARVALHO, Ana Flávia de; ALVES, Jefferson Douglas Soares
Teratology is the study of the causes, mechanisms and manifestations of deviations in both structural and functional development, embryos that were useful in the studies of a series of these anomalies and this work seeks to contribute in some way, reporting a rare case that in Brazil has not yet been described. For this case report, an animal (bird Struthio camelus) was used that had an embryonic malformation and presented with two columns, a trachea, an esophagus and the joined body, but with duplication of the limbs including the wing.
