The author studied on the 197 cases of the pleomorphic adenoma which had been diagnosed with biopsy during the period of 1985 to 1996 at the Kyungpook National University Hospital. This study contains the statistical analysis of the clinico-pathological findings such as sex, age, location, chief complaint, duration, treatment method, size, recurrence, and treatment department in relation to anatomical location. The result were as follows : 1. The treatment department in oxter were ENT(16.2%), GS(22.8%), OMFS(18.8%), PS(12.2%). 2. The incidence of pleomorphic adenoma were parotid gland(57.8%), palatal salivary gland(20.3%), submandibular gland(17.2%), other minor salivary glands(4.5%). 3. The tumors were more common in females than males, with a male to female ratio of 1 : 1.85. 4. The peak age of ocurrence was in the forth decade. 5. The duration of the most cases were less than 5 years. 6. Although the size of the tumors was variable, the incidence was highest between 3cm and 4cm(25.4%). 7. The most prevalent chief complaint was swelling(94.9%). 8. Conservative treatment was performed 30.0%, and radical treatment was employed 70.0%. 9. The recurrence rate is 8.1%, and recurrence used to be relatively common with conservative treatment. 10. The rate of malignant transformation is 1%. 11. The anatomical location has no relationship with the factors of sex, duration, and malignant transformation. 12. There was statistical significance on the anatomical location to the treatment department, age, chief complaint, size, treatment method, recurrence (P<0.05).

The purpose of this study was to investigate what the intermediate filaments in the cells of rat mandibular fossa fibrous layer are and any relationships between the presence of these filaments and aging. Mandibular fossae of 4 groups of rats(14-day, 28-day, 55-day and adult groups) were removed on bloc and processed for immunostaining and were subjected to light microscopic examination. The results were as follows : In 14-day group, there were no immunoreactive cells in fibrous layer of mandibular condyle articular surface. But in 28-day group, many immunoreactive cells were seen in fibrous layer, especially central portion of articular surface of mandibular fossa. These cells were fusiform shaped and immunoreactivities were seen in the cytoplasm around the nucleus. In 55-day group many immunoreactive cells were seen in fibrous layer of mandibular fossa. These cells were fusiform shaped and distributed evenly in central portion of this fibrous layer. Immunoreactivities were seen in the cytoplasm around the nucleus. In adult group, the results were similar to 55-day group, Many immunoreactive cells were seen in fibrous layer of mandibular fossa especially central portion. According to these results, vimentin immunoreactive filaments appear with aging and increment of mechanical load associated with incision or mastication.

The effect of long-term topical application of corticosteroids on rat cutaneous mast cells was examined under the light microscopy. Two potent corticosteroids, 0.05% clobetasol-17-propionate and 0.25% desoxymethasone, produced a remarkable decresse greater than 50% of pretreatment mast cell number by two weeks. Wheress a less potent corticosteroid, 0.1% hydrocotisone-17-valerate, produced a remarkable decrease greater than 50% of pretreatment mast cell number by four weeks. All corticosteroids produced a remarkable decrease greater than 80% of pretreatment mast cell number by six weeks. These results suggest that long-term topical application of corticosteroids may have the deleterious effects on cutsneous mast cells.
