Resumo
Na inspecção sanitária post mortem de carnes no matadouro, o exame dos gânglios linfáticos e de lesões a ele associadas adquire uma importância notória na decisão sanitária a ser emitida. Para uma correcta interpretação dos achados anátomo-patológicos em gânglios linfáticos, é essencial conhecer toda a morfologia e fisiologia do sistema linfático; a localização exacta dos gânglios linfáticos nas respectivas espécies animais, bem como a região anatómica que envolve cada gânglio e a forma como a linfa flui pelos vasos. O sistema linfático, particularmente os gângllios, podem, apresentar alterações diversas que são, em última análise, a resposta definitiva dos orgãos às agressões. Em muitas situações, é na rigorosa e ponderada interpretação destas alterações que o médico veterinário no papel inspector sanitário terá de se apoiar para emitir uma decisão sanitária correcta quanto ao destino das carnes e subprodutos.
No decurso da componente prática deste trabalho, foram recolhidos, de animais selecionados aleatoriamente, amostras de gânglios linfáticos submaxilares, ilíacos médios e inguinais superficiais. Adicionalmente, também foram recolhidos, de diferentes animais, amostras de pulmão com o respectivo gânglio linfático traqueobronquial cranial e amostras de intestino com um fragmento do gânglio mesentérico. Após sofrerem o tratamento adequado todas as amostras foram sequencialmente fotografadas e enviadas para posterior análise histopatológica. Pretendeu-se neste estudo, caracterizar macroscópica e microscopicamente os gânglios linfáticos de suíno equacionando como principal objetivo a identificação de indicadores macroscópicos que permitissem distinguir Figuras lesionais distintos (inflamação, reacção ganglionar, congestão, entre outros) e, desta forma, que pudessem auxiliar o Veterinário Oficial no decurso da sua actividade de inspeção sanitária post mortem.
The lymphatic system is responsible for lymph drainage. In the official inspection of meat and animals for slaughter, examination of the lymphatic system and injuries associated with it acquires a remarkable importance in the decision to be issued health. For a correct interpretation of pathologic findings in lymph nodes, is essential to know all the morphology and physiology of the lymphatic system, the existence and exact location of lymph nodes in the respective animal species as well as the anatomic region that surrounds each ganglion and how flows through the lymph vessels. The lymphatic system, particularly lymph nodes, can make various changes that are ultimately the definitive answer to the aggressions of the organs. In many situations, is the rigorous and thoughtful interpretation of these changes that the veterinarian in the role of health inspector must be supported to issue a proper health of the fate of the meat and byproducts. During the practical component of this work were collected randomly from different animals, different anatomic region lymph nodes as well as a fragment of the lung and intestine associated with a respective ganglion. After sustaining the proper treatment of all specimens were sequentially photographed and sent for further histopathological analysis. The aim of this study was to characterize the macroscopic and macroscopic lymph nodes of swine and relate the many changes observed in the same with some pathologies. Importantly, the conclusions found to be more focused in sanitary inspection.
