The morphological findings of the parotid, mandibualr and sublingual salivary glands of the Korean native goat have been investigated by the histological and histochemical observation using the light microscope. Tissues were fixed with 10% neutral buffered formalin and Bouin's solution, and embedded in paraffin. The tissue sections were stained with hematoxylin and eosin, Heidenhain's azocarmine-aniline blue, alcian blue, toluidine blue, periodic acid Schiff, aldehyde fuchsin, alcian blue-periodic acid Schiff and aldehyde fuchsin-alcian blue. Some sections were stained with the alcian blue after each teatment of diastase digestion, methylation, methylation-saponification, and neuraminidase digestion. The results were as follows ; 1. The major salivary glands were compound. tubuloacinar glands, and the parenchyma was composed of acini, intercalated ducts, striated ducts and excretory ducts. 2. The acini were composed of serous cells in the parotid gland, and mucous cells, serous cells and seous demilunes in the mandibular gland. The acini of the sublingual glands were composed of mucous cells and serous demilunes. 3. In histochemistry, the serous cells of the parotid gland contained neutral mucin and enzyme-liable silaic acid. 4. The serous cells and demilunes of the mandibular gland contained neutral mucin and enzyme-liable sialic acid, and the mueous cells contained sulfated mucin, enzyme liable sialic acid and neutral mucin 5. In the sublingual gland, the mucous cells contained sulfated mucin, enzyme-resistant sialic acid and neutral mucin, and the serous demilunes contained neutral mucin and enzyme-resistant sialic acid.

The ultrastructure of submandibular gland was examined in the Korean spider shrew, Sorex caecutiens. The submandibular gland wat composed of acini and salivary ducts. A submadibular acinus was a mixed gland having serous demilune cells and mucous cells that were filled with well developed rER, mitochondria and large amount of dense secretory granules. Serous acinar granules were oval shape without distinct limiting membrane on the border and it had only coarse specks with various density. Mucous acinar granules were oval shape without distinct limiting membrane and had a variety pattern with several thin or transparent bands into the homogeneous dense matrix. Thus submandibular acinar granules of S. caecutiens belonging to subfamily Soricinae were distinct from the other mammalian species including Crocidurinae, because of the absence of limiting membrane of acinar granules and specific pattern of mucous acinar granules. Granular duct cells had large amount of small granular vesicles and several characteristic structures of granule which were revered with stratified limiting membranes and filled with coarse serous-like granule or homogeneous matrix.
