“…Although MRI is becoming increasingly more essential in modern veterinary diagnostic investigations, literature review revealed just a single application in an experimental study for evaluating the function of a pilocarpine‐stimulated mandibular gland (Tsuchimochi et al., 1991). When considering sectional imaging techniques, only computed tomography was used to diagnose salivary gland neoplasia (Carberry et al., 1987; Brown et al., 1997; Sozmen et al., 2003; Shimoyama et al., 2006; Smrkovski et al., 2006; Faustino and Dias Pereira, 2007) and sialoceles or silaoliths (Hunt et al., 1997; Smrkovski et al., 2006; Bartoe et al., 2007; Trumpatori et al., 2007; McGill et al., 2009), even though MRI has superior soft‐tissue contrast (Klumpp et al., 2009).…”

This retrospective analysis documented the magnetic resonance imaging (MRI) appearance of normal salivary glands based on 101 studies in dogs with no detectable disease in the splanchnocranium. Surface, signal intensity, homogeneity, structure, symmetry and the relationship of glands to surrounding tissues were noted, and gland topography was assessed with E12 plastinated embedded sections. Signal intensity of salivary glands was isointense (7-40%) to hyperintense (60-90%) to muscle tissue on T1- and hyperintense on T2-weighted images. Salivary glands had an increased T1 signal after contrast medium was applied. Salivary gland structure appeared homogeneous in mandibular and major sublingual glands and heterogeneous in zygomatic and parotid glands. Consistent landmarks were the external auditory canal for parotid glands, the digastric muscle for mandibular and major sublingual glands, and the pterygopalatine fossa for zygomatic glands. The minor sublingual and ventral buccal glands could not be localized with low-field MRI.

“…Myoepithelial cells have rich alpha-smooth muscle actin, so alpha-SMA is a marker of myoepithelial cells 15) . In human, rat, rabbit and dog salivary glands, myoepithelial cells express the alpha-SMA [30][31][32] . In the present study, the localization of alpha-SMA in the opossum was similar to other mammals.…”

Marsupials were mammals whose young were born in an undeveloped stage and attached to the mother's nipples, usually in a pouch. Despite, these jaw elements to suckle and digestive system must develop early. Previously we have reported that the morphology of the salivary glands in the gray short-tailed opossums (Monodelphis domestica). This opossum, a kind of marsupial, has three large salivary glands which include the parotid, submandibular and sublingual glands. Parotid glands consist only of serous acinar cells. Submandibular and sublingual glands consist of seromucous secretory end pieces and the submandibular and sublingual glands were mixed glands. This study was purpose to investigate the localization of cytokeratin19 (CK19), aquaporin5 (AQP5) and alpha smooth muscle actin (SMA) in the gray short-tailed opossum parotid, submandibular and sublingual glands. These proteins localization was determined by immunohistochemistry on paraffin sections. Submandibular and sublingual glands showed a broadly similar staining pattern. CK19 was localized to the acinar cells and ductal cells in three major salivary glands. AQP5 was expressed in the luminal only of serous cells. Alpha-SMA was observed around the secretory end pieces. These results are thought to reflect the characteristic of the opossum salivary glands. Further studies are required to unravel obscure matters with cell differentiation and physiological functions of salivary glands among the mammals.

“…However, these tumors are of a rare frequency in these sites (Shimoyama et al 2006). In women, mixed tumors are extremely rare in the mammary gland, whereas these are common lesions in salivary glands (Ellis and Auclair 1996;Voz et al 2000;Kumar et al 2004;Genelhu et al 2007).…”
