Item Vascularização da cabeça de gambás(Centro Universitário da Fundação de Ensino Octávio Bastos, 2004-09-30) FRANCIOLI, André Luis Rezende; SIKINGER, Carlos Eduardo; AMBRÓSIO, Carlos Eduardo; CARVALHO, Ana Flávia de; MANÇANARES, Celina de Almeida Furlanetto; MIGLINO, Maria Angélica; ROSA, Ricardo Alexandre; HOFMANN, Roberto16 opossums from natural death or being run over were used. The techniques used were injection of 10% formaldehyde followed by injection of latex (blue for the veins and red for the arteries) in the jugular vein and thoracic aorta, in the cranial direction, respectively, and dissection of the vessels. Vascularization occurs through the common carotid arteries, which branch into internal and external carotid arteries. The jugular vein branches into internal and external. The internal carotid artery goes through divergent caudal and rostral branches to the brain, called the occipital artery. The external carotid artery goes cranially over the pharynx, branching into the facial, lingual and maxillary arteries.Item Desenvolvimento das membranas fetais em carnívoros (Canis familiaris, Linnaeus, 1758)(Fundação de Ensino Octávio Bastos, 2004-09-30) WENCESLAU, Cristiane V.; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; CARVALHO, Ana Flávia de; OLIVEIRA, Priscila C. de; FIORAVANTE FILHO, Nivaldo; ROSA, Ricardo Alexandre; MANÇANARES, Celina Almeida FurlanetoThe present study aims to provide morphological subsidies that can contribute to research in the processes of biotechnology of reproduction, as well as in vitro fertilization, cloning and obtaining stem cells, since this process in carnivores is complex and complicated. Therefore, our proposal aims at describing the structures and evolution of fetal membranes in dogs, including the process of involution of the yolk sac.Item 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 AlexandreThe 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 gapsItem 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.Item Desenvolvimento embrionário do fígado e do pâncreas de embriões e fetos bovinos(Centro Universitário da Fundação de Ensino Octávio Bastos, 2009-09-30) SANTOS, Ana Paula de Almeida; MANÇANARES, Celina Almeida Furlanetto; CARVALHO, Ana Flávia de; ROSA, Ricardo AlexandreIn domestic mammals, the increase in production rates as well as the greater dissemination of superior genetic material in herds, has been the subject of intense studies and investments, which has allowed a great advance and development of several biotechnologies related to animal reproduction. In cattle, most organs and body parts are formed between the 2nd and 6th week of gestation. During this period, the digestive tract, lungs, liver and pancreas develop from the primitive intestine, and the beginnings of the muscular, skeletal, nervous and urogenital system are established. In the course of development, the epithelial components of the digestive tract are derived from the endoderm that lines the primitive intestine and the connective and muscular components. Approximately 25 to 45% of bovine embryos are lost until the final implantation process. Due to the scarce literature related to organogenesis and the growth of technological innovations linked to bovine reproduction, the present study aims to study based on the normal development of the pancreas and liver of bovine embryos, thus generating a comparison for the understanding of numerous deformities and anomalies frequently encountered.Item Estudo macroscópico do nervo isquiático do Quati (Nasua nasua) e suas ramificações(Centro Universitário da Fundação de Ensino Octávio Bastos, 2009-09-30) SANTOS, Amilton César dos; MANÇANARES, Ana Carolina Furlanetto; BERTOSSOLI, Bruno Machado; CARLOS, Camila Zeferino; SILVA, Flávia Martins da; BENATO, Talita Mascarim; OLIVEIRA, Vanessa Cristina de; ROSA, Ricardo Alexandre; CARVALHO, Ana Flávia de; MANÇANARES, Celina Almeida FurlanettoThe coati (Nasua nasua) is a procionid with a flexible snout, small eyes and ears, which have long canines. They are omnivorous animals with diurnal, terrestrial and arboreal habits, which feed mainly on fruits and small invertebrates. This omnivore has been constituted in an important group among the animals submitted to different studies, which is extremely important even for the understanding of its own evolution, adding to the fact that detailed knowledge of its Anatomy can represent an important factor for their preservation and protection. The objective of this research is, is to know the anatomical aspects of the sciatic nerve, its origin and composition, aiming at a better understanding of the innervation of the pelvic limb of this animal. For this work, 3 orthothanged animals were used, from the Scientific Creatory (CECRIMPAS) -UNIFEOB authorized by IBAMA as the Process: nº 02027.003731 / 04-76. The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. The sciatic nerve and its branches were dissected, measured and photo documented. After analyzing the pieces studied, we could observe that the largest nerve in the coati's body is the sciatic nerve, as well as in the feline, swine and goat. This one The nerve derives its fibers essentially from the ventral branches of the lumbar nerves and from the sacral nerves that make up the lumbosacral plexus.Item Morfologia dos músculos superficiais do Quati (Nasua nasua)(Centro Universitário da Fundação de Ensino Octávio Bastos, 2009-09-30) SANTOS, Amilton César dos; OLIVEIRA, Vanessa C. de; ROSA, Ricardo Alexandre; CARVALHO, Ana Flávia de; MANÇANARES, Celina Almeida FurlanettoThe coati is an animal that belongs to the Phylum Chordata, the Mammalia Class, the Carnivorous Order and the Procyonidae Family. The striking feature of the Procyonidae family is the presence of five digits in the paws, that is, these animals are classified as plantigrade, being able to perform manual movements in different directions. He has habits of climbing trees to breed, escape danger and stay overnight. It feeds on fruits, small vertebrates, insects, nectar, eggs and vegetables. For this work, 3 orthothanized animals were used, coming from the Scientific Creatory (CECRIMPAS) - UNIFEOB authorized by IBAMA as Process: nº 02027.003731 / 04-76. The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. Muscles are individualized structures that cross one or more joints and by their contraction are able to transmit movements. In the coati the superficial muscles are: platysma, cutaneous trunk, orbicularis eye, orbicularis mouth, zygomatic, masseter, nasolabial lifter, pectoralis, abdominal, deltoid, brachycephalic, great dorsal, triceps brachial, biceps brachii, extensors, flexors, brachial, semitendinosus, semimembranosus, sartorius, biceps femoris, quadriceps, tensor fascia lata, gluteus. In this species studied, anatomical adaptations were found in the brachial and pelvic muscles that developed more than the other species (Puma, Alpaca, Dog, Cat), due to their climbing habit.Item Morfologia das glândulas salivares maiores do Quati (Nasua nasua)(Centro Universitário da Fundação de Ensino Octávio Bastos, 2009-09-30) OLIVEIRA, Vanessa Cristina de; SANTOS, Amílton Cesar dos; ROSA, Ricardo Alexandre; CARVALHO, Ana Flávia de; MANÇANARES, Celina de Almeida FurlanettoNasua nasua (coatis) are animals of daytime habit, widely found in Brazilian territory. These animals belong to the masked family as well as the naked hand. Its behavior is diurnal and its characteristic physical elements are the trumpet-shaped snout and the long tail used to maintain balance. For this work, 3 orthothanized animals were used, coming from the Scientific Creatory (CECRIMPAS) -UNIFEOB authorized by IBAMA as the Process: nº 02027.003731 / 04-76. The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. The major salivary glands were identified, dissected and photo-documented. Macroscopically, a pair of parotid glands can be seen located below the parotid-auricular muscle, ventral to the auricular cartilage and close to the mandibular gland. The submandibular glands were found just below the masseter muscle and the sublingual glands located under the mucous membrane of the mouth, between the body of the tongue and branch of the mandible, the zygomatics were shaped like a “half moon”, which was in close contact with the zygomatic arch. The glands presented on average: a mandibular gland 2.9 cm long, 1.5 cm wide and 0.8 cm thick; the parotid gland with a length of 3.4 cm, its width is 3.4 cm and thickness 0.8 cm on average; the zygomatic gland is 2.4 cm long and 0.7 cm wide; the monostomatic sublingual gland measures 1.6 cm while the polystomatic gland measures 1.7 cm, with a thickness of 0.1 cm. They consisted of 2 pairs, 1 on each side. It can be concluded that the coati salivary glands are similar to those of the other carnivores already studied.Item 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.Item Estudo da pluripotencialidade do fígado fetal canino nos diferentes períodos gestacionais(Centro Universitário da Fundação de Ensino Octávio Bastos, 2007-09-30) VIEIRA, Eduardo; MARTINS, Daniele dos Santos; WENCESLAU Cristiane Valverde; AMBRÓSIO, Carlos Eduardo; CARVALHO, Ana Flávia de; ROSA, Ricardo Alexandre; MIGLINO, Maria AngélicaThe study of the differentiation capacity of some cells, called stem cells or '' sistem '' cells represents an important tool for understanding and developing new research, as well as an enormous potential for discovering the treatment of numerous diseases. These embryonic stem cells are pluripotent, capable of multiplication and differentiation, and can proliferate in several cell types depending on the culture conditions. The identification of factors that lead to the direction of the cell differentiation process will allow, from embryonic stem cells, the culture to be carried out in a controlled manner among the most different cell types, making bioengineering possible. In this work, cells of the canine fetal liver were studied. The liver performs an important hematopoietic function during fetal development, while in the adult it has a multiplicity of functions such as: bile excretion, storage, synthesis and biotransformation. The livers, for study, were obtained from fetuses with gestational age with an average of 25, 35, 45 and 55 days, from females of mixed breed dogs that underwent ovariosalpingohesterectomy. These canine fetal liver cells were analyzed histologically to characterize cell differentiation, using previously established histological methods.
