(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.

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.

(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) SANTOS, Amilton César dos; BERTASSOLI, Bruno M.; OLIVEIRA, Vanessa Cristina de; SOUZA, Aline F.; OLIVEIRA, Franciliusa D.; ROSA, Ricardo Alexandre; SILVA, Jodonai B.; CARVALHO, Ana Flávia de; MANÇANARES, Celina Almeida Furlanetto
The coati (Nasua nasua, Linnaeus, 1766) with daytime habits and the hand-pelada (Procyon cancrivorus, G. Cuvier, 1798) with twilight and nighttime habits, are terrestrial mammal species, belonging to the procionid family that are widely found in the Brazilian territory. For this work, three coatis and two hand-peeled adults from the Scientific Creation-CECRIMPAS of the University Center of the Fundação de Ensino Octávio Bastos (IBAMA 02027.003731 / 04-76) were used. These animals had already been euthanized and used in other research prior to ours. For this research, the parotid salivary glands of coatis and hand-peeled were identified, dissected, extracted, processed and prepared for observation under the optical microscope in the hematoxylin and eosin stains, picrossirius and photocumented. Macroscopically in each of the coatis and hand-peeled, a pair of parotid glands located below the parotid-auricular muscle, ventral to the auricular cartilage, can be seen, where it is in contact with the mandibular glands that are partially covered by the parotid glands. Microscopically, the parotid glands are multilobulated and are constituted by serous acini (parotid) in the coatis. The lobes of the coatis and hand-peeled parotid glands have striated intralobular ducts, lined by simple prismatic epithelium, interlobular ducts that vary their epithelium from simple cubic to bi-stratified cubic and intercalated ducts lined by simple cubic epithelium. They are composed of serous acini, similarly to that of most domestic animals, men and rodents, and unlike the results found in young dogs, lambs and some carnivores such as the ferret that has mixed acinos and some carnivores, which have serous and mucous acinos in their constitution.

(Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) MARQUES, Mariana Nogueira; RIBEIRO, Camila; MANÇANARES, Celina Almeida Furlanetto; AIUB, Plinio Bruno; VITOR, Victório Jordão; ROSA, Ricardo Alexandre
This study compared the macroscopic anatomy of the intestine of domestic cats and the Puma concolor, which is one of the largest felines in Brazil, widely distributed throughout the country, and is highly relevant as a flagship animal that suffers enormous losses due to human action. Due to its extreme national importance, the study of its anatomy is essential for academic, clinical, surgical purposes and for actions to preserve it. Since the digestive system is one of the main agents for the homeostasis of an organism, anatomical knowledge of the intestine, the largest portion of this system, is essential. The intestine of felines is divided into the small intestine, composed of the duodenum, jejunum and ileum, and the large intestine, composed of the cecum, colon and rectum. This work aims to analyze, describe and catalog the morphology of the intestine of the puma (Puma concolor) to improve anatomical knowledge of this animal for a variety of needs, such as scientific work, clinical and surgical assistance, environmental and food management, and mainly to help preserve and conserve this species.

Rodents comprise most of the mammalian class. There are currently 2,021 species, organized into 443 genera and 29 families. Hedgehogs (Coendou villosus), are animals that in captivity, reproduce with some ease and become tame. In the urban and metropolitan region their presence is becoming common and this can be identified by the number of accidents involving dogs in the yard, registered in veterinary clinics. This work aimed to describe macroscopically the reproductive apparatus of Coendou villosus (hedgehog) to better clarify the anatomy of this important organ in the wild rodent model, since very little is known about this species. We compared the results obtained with other rodent species already studied. For the macroscopic description of the male reproductive system, 2 animals from donations were used, these animals ended up dying after attack by dogs.

The horse (Equus caballus, Linneaus 1758) is a large ungulate mammal of the Equidea family, one of the seven modern species of the Equus genus. Domesticated for thousands of years, it is an unparalleled animal, of unusual beauty, grace, sensitivity and athletic ability; a fascinating animal for study, as described by Evans et al. (nineteen ninety); Ginther (1992) and Dantzer et al. (1998). Because it is not a simple model, it offers a comprehensive range for research and challenges scientists. Equine placentation and its embryonic development are some of the issues to be explored. Thus, this study aimed to describe microscopically the embryonic attachments of the embryo / fetus of horses in the first four months of pregnancy. In order to carry out this research, 37 placentas of adult, mixed breed mares were collected and divided into groups at the different stages of development, following the methodology employed by EVANS SACK (1973), until 107 days of gestation, and were subsequently destined for the microscopy of light. The membrane fragments (corium, allantois, amnion and yolk sac) were fixed in 10% formalin and Bouin followed by routine paraffin processing (TOLOSA et al; 2003). Serial slices with a thickness of 5μm were obtained in a microtome (Leica 2165®) which were submitted to staining by the methods of hematoxylin and eosin, picrosirius, Toluidine blue and Masson's trichrome (TOLOSA et al; 2003). In the four groups, the amnion presented with a simple pavement epithelium and mesenchyme without any vascularization, only vascularization was evident when the amnion fused with the allantois, which is also a simple pavement epithelium. The corium presented villi with a low columnar epithelium and brushed edges, uni and binucleated cells, highly vascularized, and the size and quantity of villi differed from the groups. The yolk sac presented an epithelium whose cells were large and globular, resting on the mesenchyme, forming vascular islands full of hemangioblasts, being non-existent in animals from 47 to 107 days of gestation.

The purpose of this research is to describe the nasua nasua foreskin gland. Eight coatis from the CECRIMPAS Scientific Creatory (UNIFEOB) were used, the preputial glands were analyzed, dissected and described macro and microscopically, in order to establish their morphofunctional classification and thus be able to compare them with those of other species already described in the literature. Glandular tissue samples were collected, stained (hematoxylin and eosin, Toluidine blue, and picrosirius) and analyzed using light microscopy. All results were compiled and photo-documented. In the mentioned species, this gland has as its main function the territorial demarcation. In other animals such as primates, deer and rodents these demarcating glands are located in different anatomical regions, such as between the eyes, in the metatarsal, perianal and sternal. In our result of biometric measurements, we obtained an average of 3.8 ± 1.41 cm in width, 3.15 ± 0.93 cm in height and 10.26 ± 1.89 cm in circumference, and histologically classified as the tubuloalveolar type, with holocrine secretion.

This study compared the microscopic anatomy of the intestine of Puma concolor with that of the domestic cat in order to describe, evaluate and catalog the differences and similarities in the intestinal morphology of these species. The intestine is the largest portion of the digestive system and is extremely important for the proper functioning of the organism. Under microscopy, both intestines have mucosal, submucosal, muscular and serous layers; however, only the small intestine has villi, while this structure is absent in the large intestine. The microscopic intestinal anatomy of domestic and wild felines is similar. The puma is one of the largest felines in Brazil, widely distributed throughout the national territory, and is highly relevant in the country. Furthermore, it is a national animal and suffers enormous losses due to human actions. Therefore, this research aims to enrich the anatomical knowledge of Puma concolor to assist in clinical and surgical care, environmental management, and mainly in the preservation of this species.
Análise microscópica do estágio de ossificação do gambá (DIDELPHIS SP.) em diferentes estágios fetais através da diafanização e do exame radiográfico
(Fundação de Ensino Octávio Bastos, 2008-11-30) GARCIA, Fernanda Figueiredo; MANÇANARES, Celina Almeida Furlanetto; ALVES, Jeferson Douglas Soares; ROSA, Ricardo Alexandre; MIGLINO, Angélica; AMBRÓSIO, Carlos Eduardo; CARVALHO, Ana Flávia de
Opossums (Didelphis sp.) Are marsupials that have a very short gestation period, therefore, their offspring are born immature and will end their development in the mother's marsupium. Because they are very early in their development, in the fetal stage of these animals, they already have premature growth of their organs and tissues as a whole. The objective of this work was to describe the ossification stages of opossum fetuses (Didelphis sp.) At different postnatal stages, through diaphanization and radiographic examination. One animal of each age (5 days, 15 days, 22 days and 35 days) was used to verify ossification and consequent comparison with other domestic species. The results indicate a premature ossification of the species in the fetal stage, unlike domestic animals.

Large felids are species that play important ecological niches, being responsible for controlling many wild species. Therefore, in this research two jaguars (Puma concolor), jaguar I and jaguar II, fixed in formaldehyde from the collection of the Unifeob Animal Anatomy laboratory. For macroscopic analysis, these animals were weighed and their body lengths measured, to later dissect, expose and count the number of lumbar, sacral and coccygeal vertebrae. Then, the vertebrae were measured for a comparative analysis between them “in situ” and through radiographic projections, in order to define the termination of the spinal cord and measure the length of the conus medullaris, locating a safe point for the practice of the epidural anesthetic technique. and spinal. Therefore, the results found were that both had 7 lumbar vertebrae, 3 sacral vertebrae, but the coccygeal vertebrae had a variation of 21 in jaguar I and 23 in jaguar II. Exposing a spinal cord that ended in ounce I in the lumbar vertebra (L6) and in ounce II in sacral 1 (S1). Consequently, it can be concluded that the safest intervertebral space for these procedures is the sacrococcygeal space, after all, in this location the spinal cord is no longer present in pumas. Therefore, this project, considering the importance of these animals, aims to study the lumbar, sacral and beginning of the coccygeal vertebrae, spinal cord and conus medullaris, in order to improve the epidural and subdural anesthetic technique in the area of large felids, contributing to their greater use in everyday life and assisting in future literary projects.

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.

The giant anteater is a large animal and can be very aggressive with its claws if disturbed, it belongs to the Xenarthra Order, Family Myrmecophagidae, which are toothless members, and therefore called edentats. Some reports have been made about this species, but many relevant data have not been published, emphasizing basic concepts of morphology and biometrics, which could be extremely useful for the development of reproductive biotechnologies, aiming at the preservation of the species. For this study, two animals donated by UFRA – PA were used, in which the microscopic characteristics of the female reproductive system were analyzed, in order to clarify the peculiar aspects of the species. The results obtained reveal that the ovaries, fallopian tubes and uterus are similar histologically to those of domestic animals.

Keratoconjunctivitis sicca (CCS) or dry eye is a chronic inflammatory eye disease, often diagnosed in dogs and more rarely in felines. It is a disorder of the precorneal tear film, which results in a deficiency of the aqueous fraction or the mucin and/or lipid layers of the tear film, leading to inflammation of the conjunctiva and cornea, pain and reduced vision. The Schirmer tear test (TLS) is considered the main means of diagnosis. There are several causes for the onset of the disease, but the immune-mediated is believed to be the most common. Treatment is usually recommended in the use of tear stimulants and tear mimetics in addition to antimicrobials. The objective of this work was to expand the knowledge about CCS, a very common disease in veterinary medicine.
Atualização sobre sertolioma em cães
(Fundação de Ensino Octávio Bastos, 2001-11-30) CANAVES, Karla Christina; MANÇANARES, Celina Almeida Furlanetto
Sertolioma occurs more frequently in elderly and cryptorchidic dogs. Sertoli cells are responsible for physical support, protection and nutrition for developing gametes. Sertoli cells secrete estrogen, so the animal usually shows signs of hyperestrogen such as feminization, gynecomastia, alopecia and atrophy of the unaffected testis. Metastasis rarely occurs. The definitive diagnosis can be obtained through the histopathological examination of the neoplastic testis. The treatment of choice is bilateral orchiectomy.

The 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. 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. The coatis lungs were collected, analyzed macroscopically to establish the pulmonary lobation, where 4 pulmonary lobes (cranial, middle, accessory and caudal) can be found on the right side of the coatis lung and 2 left lobes (cranial and caudal). Then, the hilum was identified to check the bronchial behavior before penetrating the pulmonary parenchyma, and then the dissection started, determining the bronchipulmonary segmentation of the coatis, where it was found that the bronchial tree of the coatis has 24 segmental bronchi.

The placenta is an important structure for mammals and is responsible for making gas, excreta and metabolite exchanges between the fetus and the mother. Humans and rodents share the same placental type, a hemochorial discoid placenta. Advances in the field of tissue bioengineering have been made using the extracellular matrix of the human placenta as scaffolds, it is believed that just like the human placenta the mouse placenta can also be used as biological material for grafting and tissue recovery. This research aims to make a morphological analysis of the extracellular matrix of the mouse placenta in order to better understand this structure and its function.

The present scientific investigation aimed to study the embryonic development of pacas (Agouti Paca), with a view to the external morphological description of fetuses. Five fetuses were used, three of which were donated from the donation maintained by the Faculty of Agricultural and Veterinary Sciences of Jaboticabal - UNESP and two donated from the collection of biological material from FMVZ - USP. Fetuses 1 and 2 with 5.7 and 6.8 cm of Crow Rump, respectively, presented as morphological characteristics: marked facial immaturity, with the eyes covered by a prominent lens; the earlobes had a low level of development. The mouth had a small opening, where the formation of the incisor teeth was observed. Fetuses 3 and 4 with 9.6 and 10.5 cm of Crow Rump, respectively, showed well-developed ears, thoracic and pelvic limbs were in an equal degree of development with the presence of claws and development of facial features, like vibrissae around the nasal edges, the eyes remain protected by a prominent lens and the mouth contained the incisor teeth in an intermediate stage of development. Fetus 5, with 15.5 cm of Crow Rump, presented as a striking feature, the body covered by hair, thoracic and pelvic limbs in an equal degree of development with claws, development of facial characteristics, such as vibrissae, prominent eyes and well-developed ears. In all fetuses, the genital tubercle and the anal rim can be seen in the perineal region.

The 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 neotropical skunks today. 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 reproductive biology. The male genital system is the set of organs that form, emit and introduce the fertilizing liquid, sperm or semen. , in the pathways of the female genital system during copulation. For this research, 3 males of adult marquisupials (Gracilinanus Microtarsus) were used, which were already fixed in 10% folmaldehyde solution; provided by the Morphological Sciences Research laboratory of the University Center “Fundação de Ensino Octávio Bastos” - UNIFEOB. The male reproductive system was dissected and photographed. The information pertinent to the morphology of each organ was analyzed, described and photo documented. It is concluded that the male genital system guaiquica is similar to that of possums and consists of a pair of testicles, epididymis, deferent ducts, prostate, bulbourethral glands and bifid penis.

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.
