Abstract

The ultrastructures of the secretory acinar granules of submandibular and parotid salivary gland were examined in the Korean striped field mouse, Apodemus agraius. The acini of the submandibular salivary gland had serous and mucous acinar cells filled with numerous secretory granules. The serous acinar granules had uniformly fine dense contents and were round typed with a definite boundary between the granules. The mucous acinar granules were relatively coarse, with moderate density, and clustered together as a result of the indistinct boundaries between the granules. The acini of the parotid salivary glands contained only serous cells filled with numerous round-typed serous acinar granules. Serous acinar granules had uniformed dense matrix and definite boundaries. The ultrastructures without substructure in a matrix of serous and mucous acinar granules in the submandibular and parotid salivary glands of A. agraius were similar to those of species of Rodentia but different from those of Soricidae in Korea with a characteristic substructure in a matrix. This ultrastructure and charateristics in secretory acinar granules provide fundamental data for molecular comparisions of genetic relationships and are one of the key methods for classifying A. agraius.
