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.

This study was undertaken to observe the histopathologic changes in salivary gland of the white rats when exposed to megavoltage fractionated dose of cobalt-60 irradiation and 78 female white rats, weighing approximately 180gm, were divided into control and 3 experimental groups. Irradiation on experimental groups was delivered by using 6000 curies MeV ALCYON cobalt-60 teletherapy unit with exposure rate 183 rads per minute, in source skin distance 80cm, 600 rads every 3 days. In experimental groups, Group Ⅰwas irradiated of total dose 1200 rads for a period of 6 days, Group Ⅱ was irradiated of total dose 2400 rads for a period of 12 days and Group Ⅲ was irradiated of total dose of 4800 rads for a period of 24 days. The animals were sacrificed serially at 3 hours, 6 hours, 10 hours, 1st day, 4th day, 7th day after each completion of irradiation exposure. At sacrifice, salivary glands were excised and examined microscopically and electromicroscopically. The results were as follows: 1. The acinar cells of parotid and submaxillary gland showed damage varied with dose, 1200 rads resulted in very mild injury while 4800 rads caused most extensive injury. 2. The acinar cells of parotid and submandibular gland showed similar ultrastructural alterations, appeared as pleomorphic nucleus, decreased numbers and pleomorphism of secretory granules, distention of rough endplasmic reticulum, expansion and pallor appearance of mitochondria, and hypertrophy of Golgi complex. 3. Parotid serous cells were the most sensitive components, displaying morphological alterations of radiation damage as early as 3 hours, followed by submandibular seromucinous cells and secretory tubular cells. 4. The mucous cells of sublingual gland, as well as the whole ductal lining cells of each salivary gland, displayed no significant alterations. No evidence of microvascular injury through whole experimental groups indicated that microvascular impairment does not contribute to early salivary gland injury.

Sialolithiasis is caused by the obstruction of a salivary gland or its excretory duct by the formation of calcareous concretions or sialoliths; this results in salivary ectasia and provokes subsequent dilation of the salivary gland. Sialolithiasis is relatively common, accounting for 30% of salivary diseases; however, it is rarely observed in childhood. This case report describes a 2-year-old male patient who complained of a painful swelling over the right cheek, and presented with palpable stones and pus discharge from the orifice of the right Stensen's duct. Computerized tomography of the neck confirmed the diagnosis, and the patient received intravenous empiric antibiotics combined with intraoral sialolithotomy. We also provide a review of the spectrum of concepts regarding the pathogenesis, diagnosis, and treatment of sialolithiasis.

Warthin's tumor is a benign salivary gland tumor, occurring primarily in the parotid gland. It's incidence is 4% of all salivary gland tumors. The cytologic finding of Warthin's tumor is characteristic and it consists of sheets of oncocytes and scattered lymphocytes in the background of granular material. We reports three cases of Warthin's tumor showing characteristic cytologic findings. The patients consisted of two males and a female and their ages were 60, 73, and 69 years, respectively. All the lesions were in the parotid gland. The cytologic findings showed sheets of oncocytic epithelial cells and scattered lymphocytes in the back-ground of granular materials and many red blood cells. In one case, the back-ground was composed of many Inflammatory cells including lymphocytes, neutrophils and macrophages.

Purpose: The objective of this study was to evaluate the possibility of substitution of the zonography for the full-mouth periapical radiography in aspect of radiation protection. Materials and Methods: Rando phantom and LiF TLD chips were used for dosimetry. The absorbed doses at brain, skin above the TMJ. parotid gland. bone marrow in the mandibular body. and thyroid gland during the full-mouth periapical radiography. panoramic radiography. and zonography were measured. Resul ts: From the zonography. the absorbed doses to the brain. the skin over the TMJ. and the parotid gland were relatively high. but the absorbed doses to the bone marrow in the mandibular body and. especially. the thyroid gland were very low. Conclusion: The zonography can be an alternative to the full-mouth periapical radiography in aspect of radiation protection.

Pleomorphic adenoma is the most common benign tumor of the salivary gland. Pleomorphic adenoma occurs most commonly in the parotid gland but it may involve other salivary gland such as submandible or lingual. We report an ectopic pleomorphic adenoma in the subcutaneous layer of the face. A woman presented with a mass of the nasolabial fold. After excision of the mass, it was revealed as an pleomorphic adenoma pathologically. An ectopic pleomorphic adenoma which was located in the subcutaneous layer of the face is very rare in medical literature.

Mammary analogue secretory carcinoma (MASC) of the salivary gland is a newly classified pathologic entity since 2010. Prior to its recognition, MASC was diagnosed as low-grade cystadenocarcinoma, acinic cell carcinoma, and mucoepidermoid carcinoma. MASC shares common histological and genetic characteristics with secretory carcinoma of the breast and has a distinct feature of the ETV6-NTRK3 fusion gene. Treatment of MASC in salivary gland is mainly wide surgical resection of the tumor. Prognosis of MASC is similar to other low-grade salivary gland carcinomas. Herein, we report a case of MASC developed in a parotid gland with a review of the literature.

The salivary gland consists of major and minor glands. The major glands are parotid, submandibular and sublingual glands. The numerous minor salivary glands are located in the mucosa of the upper aerodigestive tracts. Tumors of the salivary gland are relatively uncommon, and the incidence of the salivary gland tumor among the head and neck neoplasm is approximately 3%. Surgery is the primary treatment of choice for the most tumors of the salivary glands. Author reviewed the recent reports of salivary gland neoplasms of Korea and foreign institutes and suggest the guideline of managemnt of salivary gland tumors.

Tumors of the deep lobe of parotid gland are rare. These benign tumors have usually been treated by total parotidectomy, which has functional and esthetic side effects. Recently, there has been a trend for operations of parotid gland benign tumors to be less radical and selective deep lobe parotidectomy has been introduced. This technique preserves the superficial lobe and facial nerve when tumor is located in the deep lobe. Selective deep lobe parotidectomy preserves parotid salivary function, minimizes the incidence of facial nerve damage and gustatory sweating (Frey's syndrome) and improves cosmetic outcome. We report a case of pleomorphic adenoma of the deep lobe that was successfully treated by selective deep lobe parotidectomy with satisfactory result.

The aim of this study was to establish the diagnostic criteria of normal parotid glands in adults revealing the anatomical shape, its variations and the postitional relationships of the gland. Materials included 96 lateral and anterior-posterior sialograms of selected person from 23 to 28 years of age. Results were as follows: 1. The average length and lateral displacement of main duct was 48.43㎜ and l6.88㎜. The mean lumen diameter of that was 0.91㎜ in distal end and 1.40㎜ in hilar end in parotid glands. 2. The average angle of main duct to the inferior border of mandib was 34.32 degree. In configurations of main duct, modified curvilinear type was. most prevalent and followed by curvilinear, reverse sigmoid, sigmoid type. 3. The mean caliber of parotid gland was the longest in superior-inferior. 4. The interlobar ducts showed relatively well defined in all cases, its average number was 5.72. Arrangement of these ducts showed at random. Accessory lobe showed 87.5% in the all cases, its average number was 1.7. 5. There were no difference between the well and poorly defined acinar fillings in the glandular parenchyme. 6. There were no differences between right and left parotid glands in size and shape of main duct and parenchymal portion, but there were great variations in each individuals.
