Item Ações biológicas das prostaglandinas na reprodução de fêmeas bovinas(Centro Universitário da Fundação de Ensino Octávio Bastos, 2004-09-30) ALVAREZ JÚNIOR, Roberto Aparecido; TUNIN, Adriana Maria Favaro; ROSAS FILHO, Adauto de CarvalhoProstaglandins are members of a large family of endogenous compounds, known as eicosanoids, derived from oxygenated fatty acids, unsaturated and synthesized in most mammalian tissues. The fact that concentrations increase during childbirth or abortion confirms the participation of this hormone in these processes. PGF associated with oxytocin causes myometrial contraction and PGE due to its spasmodic action on the anterior portion of the uterus, has a relaxing effect on the cervix. They are likely to participate in addition to uterine contraction, with events such as the occlusion of the umbilical vessels and the closure of the venous arterial duct.Item Monitoramento do ciclo estral de éguas por meio de ultrassonografia e biopsia uterina(Centro Universitário da Fundação de Ensino Octávio Bastos, 2004-09-30) GODOY, Tiago Preto de; OLIVEIRA, Priscila Carvalho de; ROSAS FILHO, Adauto de Carvalho; PICHOTANO, Maria Emília; FIGUEIREDO, Cristiane LeiteThe use of ultrasonography has facilitated the real-time characterization of ovarian structures and uterus, being able to follow the waves of follicular development and endometrial changes. However, it is not the only alternative to monitor the mitotic activity of the endometrium. The use of histology and immunohistochemistry, through uterine biopsy can be performed to monitor endometrial changes responsive to hormones, as well as to detect possible problems of subfertility.Item Uveíte equina recidivante induzida por leptospirose(Centro Universitário da Fundação de Ensino Octávio Bastos, 2004-09-30) CASTANHO, Daniele Pescantini; TUNIN, Adriana Maria Favaro; ROSAS FILHO, Adauto de CarvalhoOcular leptospirosis is also called periodic uveitis or ophthalmia in horses. Leptospirosis-induced uveitis is an autoimmune disease, that is, it is believed that there is deposition of immune complexes against the bacteria present in the eye, since it has a preference for sites with low immunological load. The disease can be detected after one or two acute episodes, or it can proceed through several acute episodes with the end result, loss of vision. Because there is no effective treatment, correct sanitary and hygienic management is necessary, since the bacteria is transmitted through the urine of rats.Item Insuficiência hepática: relato de caso(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) BARROS, Mariana Cabral Ruggero; FALCÃO, Sara Carolina Fernandez; ABREU, Rogério Navarro de; FERREIRA, Francisco Pupo Pires; ROSAS FILHO, Adauto de CarvalhoThe liver has functions of metabolism, excretion and synthesis of some substances important to the body. The most commonly observed signs are anorexia, depression, colic, weight loss, jaundice, dysfunctions in the central nervous system, photosensitization, ventral edema and hemorrhages Liver failure can be caused by toxic plants, infectious, neoplastic causes, by the use of medications. The information collected during anamnesis, complete blood count and biochemical examination (enzymes AST, GGT, Alkaline Phosphatase, SDH) are essential for the diagnosis of the condition. An Apaloosa horse, 12 years old, 436 kg showed signs of acute abdomen on the 19th of March 2011 and was sent to Hospital Veterinário Vicente Borelli located in São João da Boa Vista on the 21st of March of the same year, but without evidence of abdominal pain and with a report of a fracture in the posterior limb two years ago, at which time many medications were administered and a history of progressive weight loss a month ago. Through anamnesis and complementary exams, tubular renal injury and liver failure were diagnosed. The animal received forty liters of intense fluid therapy when it arrived at HOVET. Antibiotic, anti-inflammatory, omeoprazole as gastric protector and an alternative supplementation with albumin and powdered dextrose due to low serum amounts of glucose and albumin were also instituted in this animal.Item Análise morfológica de embriões ovinos produzidos em laboratório a partir de oócitos aspirados de doadoras multíparas, primíparas e pré - púberes da raça Santa Inês(Centro Universitário da Fundação de Ensino Octávio Bastos, 2011-05-30) MARTINS, João Flávio Panattoni; SANTOS, Thainá de Oliveira; SILVA, Marcos Donizete da; SOUZA, Bruna Manzer de; OLIVEIRA, Priscila C. de; ROSAS FILHO, Adauto de Carvalho; ABREU, Rogério Navarro de; FIGUEIREDO, Cristiane LeiteThis work aimed to analyze the morphology of embryos at seven days of development, produced in the laboratory from oocytes aspirated from three different classes of donors of the Santa Inês race (multiparous, primiparous and prepubertal). The analyzed embryos had a discoid shape and were delimited by the pellucid zone (ZP). In the morula and initial blastocyst stages, the ZP measured from 5 to 10 μm in thickness, revealing to be thinner in the expanded blastocyst phase. In general, the structure and ultrastructure of Santa Inês sheep embryos, originating from in vitro fertilization (IVF) and evaluated in this study, corroborate many of the observations by Colarco and Mclaren (1976), Ferrer et al. (1995) and Coccero et al. (2002). The most striking aspect was the intense uniform distribution of lipid inclusions in the cytoplasm of the blastomeres, both in the internal cell mass and in the trophoblastic cells, regardless of the origin of the oocyte, suggesting that the morphology seems to be conditioned mainly to the culture system employed, which seems to favor the accumulation of intracellular lipids.Item Estudo de embriões ovinos em laboratório a partir de doadoras juvenis da raça Santa Inês submetidas a estimulação ovariana(Centro Universitário da Fundação de Ensino Octávio Bastos, 2010-05-30) MARTINS, João Flávio Panattoni; SANTOS, Thainá de Oliveira; SILVA, Marcos Donizete da; SOUZA, Bruna Nanzer; OLIVEIRA, Priscila Carvalho de; FIGUEIREDO, Cristiane Leite; ROSAS FILHO, Adauto de Carvalho; ABREU, Rogério Navarro deThis study aimed to verify the superovulatory response of juvenile Santa Inês sheep and to evaluate the viability of oocytes obtained for in vitro production (IVP) of embryos. Eight females aged between 6 and 8 weeks were selected, distributed in 2 homogeneous groups of 04 animals. The females in Group 1 (G1) were submitted to exogenous ovarian stimulation and in Group 2 (G2) the females were aspirated free of hormonal treatment. From a total of 309 retrieved oocytes (G1 = 187 and G2 = 122), cleavage rates of 49.2% and 40.2% were obtained for G1 (n = 92) and G2 (n = 45) respectively, and 18.72% and 17.96% of viable embryo development in D7 (G1 = 35 and G2 = 19). Although the results suggest a better efficiency in the recovery of oocytes and cleavage rate in G1, the rates of obtaining viable embryos in D7 did not differ numerically between the two groups. Our results suggest that, although there was great variation in the amount of oocytes obtained and the production of embryos among animals, regardless of treatment, the production of embryos by in vitro fertilization (IVF) from juvenile females treated or not with exogenous hormones proved to be viable, even with good efficiency of the hormonal protocol used for females of the Santa Inês breed.Item Toxemia da gestação de ovelhas(Centro Universitário da Fundação de Ensino Octávio Bastos, 2008-11-30) MORAES, Maria Eugênia; ROSAS FILHO, Adauto de CarvalhoThis literature review aims to present the main aspects of pregnancy toxemia in sheep, as this is a very common cause of death in sheep in the final third of pregnancy. Pregnancy toxemia usually occurs in sheep with two or three fetuses (ORTOLANI, 1996 and VIANA, 2001) or when there is a single bulky fetus (DEGOIS, 1985 and NAVARRE & PUGH, 2002). It is a metabolic disorder determined by an inadequate diet during pregnancy, causing acetonemia, hypoglycemia and systemic acidosis and manifesting digestive signs such as anorexia and nerves such as nervous depression and prostration (ORTOLANI (1996) and (VIANA (2001)). Two organic conditions and of the pregnant woman can cause TG, type I occurs due to the state of malnutrition during the period of concomitant pregnancy with the presence of multiple fetuses (ORTOLANI, 1996 and 2007 and VIANA, 2001). gestation (ORTOLANI, 1996) .Treatment should be aimed at combating hypoglycemia, decreasing glucose drainage and reducing ketoneogenesis (ORTOLANI, 1996 and VIANA, 2001), however the disease prognosis is in most cases. bad cases and therefore prevention through proper food management is very important (ORTOLANI, 2007).
