Item Estudo morfológico sobre testículos do tatu galinha(Fundação de Ensino Octávio Bastos, 2001-11-30) LIMA, Marcelo C. de; CARVALHO, Ana Flávia de; AMBRÓSIO, Carlos Eduardo; BONATELLI, MarinaAnatomically, the testicles were located in the hypogastric, intra abdominal region in a longitudinal cranial - caudal position with an oval shape. The epididymis was found in the dorsal mid region of the testis DYCE et al (1997). The right testicle weighed 6.48 g and the left 6.23 g; they respectively measured 3.1 cm and 3.4 cm in length and 2.6 cm and 2.6 cm in width, showing a certain regularity in shape and size. The right epididymis measured 8.5 cm and the left 6.0 cm. Microscopically the testicular structures found were similar to those of other animals with characteristic germinal epithelium (spermatogonia, spermatocytes of 1st and 2nd order and spermatoids). Leydig cells were observed in large numbers.Item Estudo do desenvolvimento prostático em cães neonatos da raça Rotweiller(Fundação de Ensino Octávio Bastos, 2001-11-30) LIMA, Marcelo C. de; CARVALHO, Ana Flávia de; BANDARRA, Enio P.; LAUFER, Renne; BONATELLI, MarinaFour Rotweiller dog prostates were used, neonates analyzed macro and microscopically. They were anatomically positioned, caudally after the urinary bladder, entering the pelvic bone. They showed a tissue mass surrounding the pelvic urethra. They had two wolves measuring 0.9 cm long and 0.6 cm wide, with a volume of 0.82 ml, and weight 0.80 g. Histologically, the prostatic body was covered by connective tissue and tubule - alveolar portions were observed whose alveoli were covered by an epithelium not yet defined. The stroma had dense non-modeled connective tissue surrounding the secretory portion and muscle fibers. Among the wolves, we observe the prostatic urethra.Item Estudo dos dentes de Guaiaquica(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) LOBO, Luis M.; SANTOS, Amilton César dos; ROSA, Ricardo Alexandre; CARVALHO, Ana Flávia de; MANÇANARES, Celina de Almeida FurlanettoThe guaiquica (Gracilinanus microtarsus), belongs to the family Didelphidae, which is a very important family among marsupials, because in addition to containing many species (like opossums), it represents the model group of marsupials. Marsupial ancestors, from the Cretaceous period, had morphological characteristics very similar to those of today's Neotropical skunks. For this reason, their reproductive adaptations are considered directly related to primitive marsupials, and this similarity is of great interest for the comparative study of their biology. The teeth together with the gums, the temporomandibular and symphysial joints of the jaws, and also the masticatory muscles, constitute the masticatory apparatus. This work aims at the morphological characterization of the teeth of guaiquica for a better understanding of evolutionary aspects related to marsupials and other mammals.Item Análise morfológica das células do aspirado medular de fetos caninos(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) MÁRIO, Lara Carolina; BORGHESI, Jéssica; MELLO, Ana Carolina Landentin; MIGLINO, Maria Angélica; AMBRÓSIO, Carlos Eduardo; MARTINS, Daniele; CARVALHO, Ana Flávia de; WENCESLAU, Cristiane ValverdeThe adult bone marrow is a source of stem cells (CT), which include the hematopoietic stem cells (HSC) that originate the entire definitive hematopoietic lineage; and mesenchymal stem cells (MSC), and or stromal which are responsible for providing a favorable environment for hematopoiesis. In addition to these main cell types, bone marrow is composed of several parents, differentiated cells and an extracellular matrix. This environment where CT is found is called a niche, as it houses a large amount of CT and cellular progenitors that are kept quiescent, acting normally and or in the face of injuries. However, little is known about the fetal bone marrow niche. It is known that the bone marrow niche is derived during the ontogenesis of the yolk sac, which subsequently migrates to various hematopoietic organs such as the placenta and liver, ultimately settling in the bone marrow. Thus, the present work aims to describe morphologically the cell types of canine fetal bone marrow at 40 and 60 days of gestation. For this purpose, 6 pregnant female uteri were used to collect the medullary aspirate from the femur bone and later structural and ultrastructural morphological analysis. The results demonstrated that the canine fetal bone marrow at 60 days of gestation has cell types similar to that of the adult bone marrow as well as CT, thus being able to be used as a source of CT isolation.Item Estudo macroscópico dos dentes de Guaiaquica(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) LOBO, Luis M.; SANTOS, Amilton César dos; ROSA, Ricardo Alexandre; CARVALHO, Ana Flávia de; MANÇANARES, Celina de Almeida FurlanettoThe guaiquica (Gracilinanus microtarsus), belongs to the family Didelphidae, which is a very important family among marsupials, because in addition to containing many species (like opossums), it represents the model group of marsupials.

As it is an animal of our fauna, data about the species, with regard to morphology and physiological aspects, are very scarce, and generally focus on diseases and external parasites, from capture and expeditions. For this study, two animals donated by UFRA – PA were used, in which the macroscopic characteristics of the female reproductive system were analyzed, in order to clarify the morphological aspects of the female reproductive system, peculiar to the species, in order to assist in their preservation and create reproductive biotechnology tools. The obtained results reveal that the ovaries are longilinear, the uterine tubes tortuous, and the simple uterus in pear shape, as well as in the sloth, in the woman and in the primates. The cervix is quite thick and the vagina communicates with the vestibule and the vulva.Item 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 deTo 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.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 Morfologia macroscópica do ovário de Agouti Paca(Fundação de Ensino Octávio Bastos, 2008-11-30) ROSA, Felipe Gonçalves; CARVALHO, Ana Flávia de; ROSA, Ricardo Alexandre; MACHADO, Márcia Rita Fernandes; MaNÇANARES, Celina de Almeida FurlanettoAccording to Alho (1982) the paca belongs to the Rodentia Order, Suborder Hystricomorpha and to the family Cuniculidae, genus Agouti and species Cuniculus paca or Agouti paca (Linnaeus, 1766), known as common paca. This work aimed to characterize morphologically the pacas ovary (Agouti paca) through macroscopic analysis. For this research, four adult pacas were used, two pregnant and two non-pregnant. Partial ovariectomies were performed by removing only one ovary. The ovaries were fixed in a 10% formaldehyde solution in 0.1M phosphate buffer pH 7.4 for a period of 48 hours. After fixation, the ovaries were analyzed, measured and photographed. In all the specimens examined, it was observed that the paca's ovaries had an ovoid shape, yellowish pink color, nodular appearance due to projections on the cortical surface of follicles and corpus luteum.
