A UNIFEOB mantém uma política de pesquisa que tem como objetivo orientar as ações desenvolvidas nesse campo do conhecimento. As pesquisas têm alicerce em princípios e critérios de produção de conhecimento científico e tecnológico, seguindo normas éticas de pesquisa em seres humanos e animais e dissociada do ensino e da extensão. As atividades convergem com as diretrizes nacionais, visando o desenvolvimento sustentável social, econômico e ambiental.

    Retículo esplenite traumática associada á peritonite em bovino: Relato de caso
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) OLIVEIRA, Braian Rombaldo de; TAGLIAFERRO, Karoline Saturnino; ALVISI, Renato Duarte; FREITAS, Renan Contini de; FAGUNDES, Juliana Portela Gonçalves; MELO, Larissa Martarella de Souza; BIRGEL, Daniela Becker; BIRGEL JÚNIOR, Eduardo Harry
    The ingestion of foreign bodies by ruminants is the result of non-selective feeding, the anatomy of the fore-stomachs and the presence of sharp objects in pastures. Traumatic reticulo-splenitis is a disease with low frequency in ruminant clinical practice. It occurs due to the ingestion of sharp foreign bodies, which causes perforation of several organs in the abdominal cavity. The proximity of the reticulo-splenitis to several organs, associated with the presence of sharp objects in pastures and feeders are important factors to be analyzed, which cause several pathological processes, including traumatic reticulo-pericarditis, traumatic reticulo-peritonitis, traumatic reticulo-hepatitis and traumatic reticulo-splenitis. There are no characteristic clinical signs of traumatic reticulo-splenitis, nor specific diagnostic methods, where the spleen of cattle, for example, cannot be examined through transrectal palpation. When ingested by the animal, the sharp object follows the flow of the food bolus and remains trapped in the reticulum, where, through physiological contraction, it can perforate the organs adjacent to it. After this, the object can perforate other organs, carrying microorganisms to the site of the injury, causing an infection and malfunction of the organ. Therefore, the present study aims to report a case of traumatic reticulum splenitis in a bovine.

    Efeito do estresse agudo sobre a secreção de prolactina em ratas nulíparas e primíparas
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2008-11-30) ALVISI, Renato Duarte; HUCKE, Erica Elgelberg da Silva
    Prolactin is an important hormone responsible for the development of the mammary glands during pregnancy and for the production of milk during the postpartum period. It has been concluded through several studies that the production of prolactin can suffer interference from various stressors, thus resulting in increased production. Physiological factors such as reproductive experience also have an influence on prolactin, but they act in a way to decrease its production. In recent studies carried out on adrenalectomized rats, we observed that the modulation of prolactin secretion exerted by adrenal glucocorticoids does not have the same modulatory effect as a function of reproductive experience, thus indicating that primiparous females would not be as sensitive as nulliparous females to circulating levels of glucocorticoids, which could be suggestive less stress sensitivity. Other experiments carried out with nulliparous and primiparous rats on the influence of acute and prolonged stress on prolactin secretion showed that the reproductive experience does not seem to modify the serum prolactin concentration in response to acute and prolonged stress. However, the acute response could have occurred in less than an hour, the objective of this study being to study the secretion and concentrations of prolactin during the first hour after stimulation of acute stress in primiparous and nulliparous rats.
