Resumo: | Histological studies in wild birds are still incipient, taking into account the great diversity of species and the difficulty to obtain material for analysis. Due to this scarcity, we aimed to describe the microscopic lung morphology of two terrestrial wild birds. To do this, we used a specimen of Ardea alba – Linnaeus, 1758 (great egret) – and a specimen of Caracara plancus – Miller, 1777 (southern caracara) –, which were taken to the Center for Rehabilitation of Wild Animals (CRAS) of Universidade Estácio de Sá (UNESA), in Vargem Pequena, Rio de Janeiro, Brazil, by members of civil society and government care and protection agencies; however, they did not survive their injuries and died naturally. The animals were dissected and their lungs were fixed in 10% formaldehyde aqueous solution, to apply routine histological technique, revealing a differentiated structure in the organ with a bronchial branching pattern that consists of mesobronchus, secondary bronchus, and parabronchus, as well as absence of classical lung alveoli, whose function is performed by air capillaries. Results point out the microscopic resemblance to poultry and confirm the complex architecture to enhance gas exchange. |

Os estudos histológicos em aves silvestres ainda são incipientes, levando em consideração a grande diversidade de espécies e a dificuldade de obter material para análise. Em virtude dessa escassez, objetivou-se descrever a morfologia microscópica do pulmão de duas aves silvestres terrestres. Para tanto, foi utilizado um exemplar de Ardea alba – Linnaeus, 1758 (garça-branca) – e um exemplar de Caracara plancus – Miller, 1777 (gavião caracará) –, que foram levados ao Centro de Reabilitação de Animais Silvestres (CRAS) da Universidade Estácio de Sá (UNESA), em Vargem Pequena-RJ, por membros da sociedade civil e órgãos de cuidado e proteção do governo; entretanto, não resistiram às lesões e vieram a óbito de maneira natural. Os animais foram dissecados e seus pulmões foram fixados em solução aquosa de formaldeído a 10%, para aplicação da técnica histológica de rotina, revelando estrutura diferenciada do órgão com um padrão de ramificação bronquial composto por mesobrônquio, brônquio secundário e parabrônquio, bem como pela ausência de alvéolos pulmonares clássicos, cuja função é desempenhada pelos capilares aéreos. Os resultados apontam a semelhança microscópica com aves domésticas e confirmam a complexa arquitetura para amplificar a troca gasosa.Universidade Federal de Santa Catarina2014-08-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2014v27n4p10110.5007/2175-7925.2014v27n4p101Biotemas; v. 27 n. 4 (2014); 101-1052175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2014v27n4p101/28024Copyright (c) 2014 Bianca da Silva Salmon Pompeu, Verônica Clemente Villar Martini, Luís Gustavo Oliveira Picorelli, Jeferson Rocha Pires, Bruno Murilo da Silva Freitas, Jonathas da Cruz Fariasinfo:eu-repo/semantics/openAccessPompeu, Bianca da Silva SalmonMartini, Verônica Clemente VillarPicorelli, Luís Gustavo OliveiraPires, Jeferson RochaFreitas, Bruno Murilo da SilvaFarias, Jonathas da Cruz2017-10-19T17:43:35Zoai:periodicos.ufsc.br:article/33064Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T17:43:35Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
