Resumo: The knowledge regarding labial salivary glands is becoming progressively more important, as their application in autologous transplantion, to promote ocular surface lubrication, are an ever-increasing procedure in veterinary medicine. In this study the labial salivary gland was collected, as a single piece, along with the oral mucosa from 10 adult dog cadavers. The sample was removed from the left lower lip marked by the second premolar tooth and extended until the distal edge of the second molar. Morphological, morphometric and histochemical evalutations were performed in the rostral, medial and caudal regions of the sample. The study revealed exocrine, compound, tubuloacinar, mixed and predominantly mucous glands with the presence of serous demilunes associated with a few mucous secreting units, and a duct system formed by intralobular intercalated and striated ducts, interlobular ducts, and a main excretory duct. In the rostral region, there was a lower amount of parenchyma compared to other areas, and the diameter of the acini unvaried in all regions. All three regions of the sample were PAS and Alcian blue positive, demonstrating the presence of neutral, carboxylated, and sulphated mucins. Serous demilunes reacted positively to Xylidine Ponceau staining indicating the presence of proteins.

As glândulas salivares labiais, juntamente com a mucosa oral, foram removidas de 10 cadáveres de cães adultos, como peça única, no lábio inferior esquerdo, da região anatômica do segundo dente pré-molar até a borda distal do segundo molar e amostras das regiões rostral, média e caudal da peça foram processadas para avaliações morfológicas, morfométricas e histoquímicas. O estudo revelou glândulas exócrinas, compostas, túbuloacinosas, mistas, predominantemente mucosas, com presença de semiluas serosas associadas a algumas unidades secretoras mucosas, sendo seu sistema de ductos formado por ductos intralobulares intercalares, ductos intralobulares estriados, ductos interlobulares e ducto excretor principal. Na região rostral havia menor quantidade de parênquima em relação às demais regiões, e o diâmetro dos ácinos se manteve equivalente nas três regiões. Houve reação positiva ao PAS e ao Alcian blue nas três regiões, demonstrando presença de mucinas neutras, ácidas carboxiladas e ácidas sulfatadas. As semiluas serosas apresentaram reação positiva ao Xylidine Ponceau, indicando presença de proteínas.UEL2016-10-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Originalapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2160610.5433/1679-0359.2016v37n5p3079Semina: Ciências Agrárias; Vol. 37 No. 5 (2016); 3079-3086Semina: Ciências Agrárias; v. 37 n. 5 (2016); 3079-30861679-03591676-546Xreponame:Semina.
