Resumo: | Of 149.394 horses slaughtered in Brazil for consumption, there were 32 cases of suprarenal hyperplasia (0,02%). In four cases, the process was clearly nodular, and in 28 cases the lesions were difuse. In the nodular forms, the nodosities were found in the poles of the gland, reaching the size of a chicken egg. In the difuse forms, the gland showed a uniform hypertrophy and its parenchyma exhibited different aspects. Microscopically examined, there was a predominance of a simple hyperplasia process; in certain cases, the hyperplasia culminated in the liberation of cholesterol crystals and their calcification; in a few cases only, the gland exhibited different signs of necrosis. The hyperplasic cells were rich in fats, reaching a scummy aspect, somewhat similar to an adipose cell. Those fats were sudanophilic. The process studied is probably correlated with castration, since most of the examined animals were in this condition. But it is also possible that those hyperplasias were induced by stress, this caused by intense muscular strain, since the examined material was from work and saddle horses. |

Em quatro casos, o processo era nitidamente nodular e em 28, a lesão era de caráter difuso. Nas formas nodulares, as nodosidades se localizavam nos polos da glândula, atingindo até o volume de um ovo de galinha. Nas formas difusas, a glândula se mostrava uniformemente hipertrofiada, apresentando o seu parênquima, aspectos variados. Microscopicamente verificava-se predominância de processos de hiperplasia simples; em certos casos, a hiperplasia culminava com a libertação de cristais de colesterol e sua calcificação; em um número limitado de casos, a glândula exibia necrose. As células hiperplásicas mostravam-se ricas em lipídeos, assumindo aspecto escumoso ou comparável ao da célula adiposa. Tais lipídeos eram sudanófilos. O processo estudado deve estar correlacionado com a castração, já que a maioria dos animais observados era constituída de indivíduos castrados. Entretanto, provindo o material trabalhado de animais de sela e eventualmente de tração, não se pode desprezar a possibilidade da participação do "stress" por intenso trabalho muscular na génese de tais hiperplasias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Jefferson Andrade dosPires, Amaury RomeiroSilva Junior, José Fernandes da2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16629Pesquisa Agropecuaria Brasileira; v.14, n.1, jan. 1979; 1-9Pesquisa Agropecuária Brasileira; v.14, n.1, jan. 1979; 1-91678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16629/10932info:eu-repo/semantics/openAccess2014-04-15T19:21:29Zoai:ojs.seer.sct.embrapa.br:article/16629Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:21:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
