SIALOGRAPHIC CHARACTERIZATION OF THE NORMAL PAROTID-GLAND OF THE MINIATURE PIG

Objective: To characterize the structure of the parotid gland of the m iniature pigs (minipig). Methods: Sialographic, anatomical, histologic al and ultrastructural studies of the parotid gland were performed on 11 minipigs, Results: Sialograms showed a long main duct and a triangu lar shaped gland. All blanching ducts extended from the inferior-poste rior margin of the main duct. No accessory glands were found. Typical serous acini were found microscopically and histochemically. Conclusio n: This study provides basic structural information on the parotid gla nd of the minipig.
