Resumo: | Canine endocrinopathies, such as hypothyroidism and hyperadrenocortism,induce typical dermatological alterations. Collagen fibers are significant for the maintenance of structural integrity,as well as in the determination of tissue function. This study aimed at assessing the coloration caused by Picrosirius Red staining under circular polarization and Masson Trichrome staining, as tools to quantify the total collagen in the skin of dogs exhibiting endocrine dermatopathies. Skin samples taken from dogs with hypothyroidism and hyperadrenocorticism were stained using Hematoxylin and Eosin (HE), Masson's Trichrome (MT) and Picrosirius Red (PSR). The animals with hyperadrenocorticism revealed a higher percentage of collagen area than did the animals with hypothyroidism PSRp (hypothyroidism = 43.76 ± 0.8255 and hyperadrenocorticism = 47.08 ± 0.8584). The percentage of the collagen area using MT between the groups is given in parenthesis (hypothyroidism = 52.06 ± 0.9371, hyperadrenocorticism = 61 ± 0.7529 and control = 56.88 ± 0.64) (p <0.05). It is therefore, evident that the special stains employed are useful in estimating the percentage of collagen area in the skin, as they revealed that dogs with hypothyroidism had lower collagen deposition whereas those animals with hyperadrenocorticism showed higher quantity of collagen in the dermis.Keywords: canine endocrinopathies, skin, fibrosis,Picrosirius Red, polarization |

As fibras de colágeno desempenham um papel vital na manutenção da integridade estrutural e também na determinação da função dos tecidos. O objetivo deste estudo foi avaliar as colorações de picrosirius red sob polarização circular e coloração tricômio de Masson como ferramentas para quantificar o colágeno total da pele de cães com dermatopatias endócrinas. Amostras de pele obtidas de cães com hipotireoidismo e hiperadrenocorticismo foram coradas por Hematoxilina e Eosina (HE), Tricrômio de Masson (MT) e Picrosirius red (PSR). A porcentagem de área de colágeno foi maior nos animais com hiperadrenocorticismo e menor nos animais com hipotireoidismo PSRp (hipotireoidismo = 43,76 ± 0.8255 e hiperadrenocorticismo = 47,08 ± 0.8584). Já a porcentagem de área de colágeno no MT entre os grupos (hipotireoidismo = 52,06 ± 0.9371, hiperadrenocorticismo = 61 ± 0,7529 e controle = 56,88 ± 0.64) (p <0.05). Concluiu-se que as colorações especiais utilizadas são úteis para avaliar a porcentagem de área de colágeno na pele, pois demonstraram que cães com hipotireoidismo demonstraram uma diminuição na deposição de colágeno e os animais com hiperadrenocorticismo apresentaram maior quantidade de colágeno na derme.Palavras-chaves: hipotireoidismo; hiperadrenocorticismo; fibrose; colágeno.Universidade Federal de Goiás2019-09-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/55398Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 20 (2019): Continuous publication; 1-10Ciência Animal Brasileira / Brazilian Animal Science; v. 20 (2019): Publicação contínua; 1-101809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/vet/article/view/55398/33723https://revistas.ufg.br/vet/article/view/55398/33724Copyright (c) 2019 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessCosta, Glícia MenesesAraujo, Steffi LimaXavier Júnior, Francisco Antônio FélixMorais, Glayciane Bezerra deSilveira, João Alison de MoraesViana, Daniel de AraújoEvangelista, Janaina Serra Azul Monteiro2023-03-23T18:49:21Zoai:ojs.revistas.ufg.br:article/55398Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:23.844911Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
