With aging, several progressive changes occur on the midface including descent of attenuated lower eyelid skin which creates a skeleton-like appearance with infraorbital hollowness, and descent of the malar fat pad with exaggeration of the nasolabial fold. Most of the procedures for midfacial rejuvenation require extensive peripheral-to-central dissection in the subcutaneous, sub-SMAS or subperiosteal plane. The author's procedure entails direct access to the midface through a subciliary incision, elevation of the orbicularis oculi muscle and ptotic malar soft tissue. It has been performed through subcutaneous dissection on 67 patient and subperiosteal dissection on 4 patients. Subcutaneous dissection on the midface was made laterally to the zygomaticus maior, medially to the levator labii superioris under the oricularis muscle and inferiorly beyond the nasolabial fold. The range of subperiosteal dissection was similar to subcutaneous dissection, except on the dissection plane. Suspension sutures made at the malar retaining ligament and infero-lateral portion of the orbicularis oculi were fixed to periosteum of the lateral canthal area. In some patients, this procedure was combined with forehead lift(4), temporal lift(2), upper blepharoplasty(28), cervicoplasty(2), and lateral canthoplasty(12). In 23 patients who had a particularly prominent tear trough, a fat sliding technique was combined. The author has followed up 62 patients from a minimum 2 months to a maximum 27 months. Complications included urdercorrection(3), longstanding malar fullness(2), ectropion(1), transient numbness(2), and cheek dimpling(1). In conclusion, this centrofacial can be applied to patients who have limited ptosis of the midface with mild nasolabial fold.

The nucleolus of human cell is a morphologically well recognizable nuclear organelle and the argyrophilic NORs (AgNORs) are nucleic acid-argyrophilic nonhistone protein complex in the nucleoli and the silver staining allows their identification and enumeration at the light microscopic level. The AgNOR counts are in parallel with mitotic activity and vary in different phase of cell cycle. It has been reported that human cells have one AgNOR during interphase and S-phase. However, the correlation between the number of AgNORs and S-phase markers is still controversial and they have never been studied simultaneously. In this study, AgNOR and PCNA were stained simultaneously to find out the relationship of AgNOR counts with cell cycle (S-phase) in human palatine tonsil, gastric carcinoma, liver and brain tissues. S-phase cells (PCNA-positive) were found predominantly in lymphoid follicles in palatine tonsil but gastric carcinoma showed diffuse immunoreactivity for PCNA. The AgNOR counts varied according to the type and locus of tissue. More than one AgNOR were identified in S-phase cells and some of hepatocytes and neurons in the brain which were not in S-phase contained two or more AgNORs. The above results suggest that the number of AgNOR is a characteristic feature of each type of cells and can be more than one even in S-phase.

The presence of cartilage in a glial tumor is exceptional. It frequently occurs in ependymoma of midline location in young child nuder 5 years of age. The mechanism of cartilage and bone formation in ependymoma is thought to be either metaplastic transformation from mesenchymal tissue or direct transformation from the neoplastic glial cells. A case of ependymoma containing cartilage and bone is reported. The patient is a 4 year-old girl, having calcified mass in the 4the ventricle and cerebellar vermis. The pathogenesis of cartilage formation in this ependymoma is more likely to support the mataplastic theory.

The propose of this study was to propose for protection of childhood injury or accident and to provide safety measures. Data was collected from 2,052 who visited emergency room of E University Hospital during 1 year period form January to December, 1996. The results were as follows : 1. The most common type of accident was fall down (53.4%). 2. Male patients outnumbered female by the ratio of 1.68 : 1. 3. The highest incidence rate of accidents were observed in children between 1-3 years age group(34.9%). 4. Accidents were seasonally more frequent in spring(28.2%). 5. Accidents mainly took place at home(63%). 6. The time of accidental occurrence appeared to be predominantly high during a day 8:00 PM to 0:00 AM(35.1%). 7. The most frequent involved part of body was head and face(74%). 8. Most patients discharged from the hospital in good condition(85.4%). Though clinical analysis, in the relation to accident, there were statistically significant difference in sex, age, season, injury place(all=0.000).

Gastric mucosa shows continuous changes in surface epithelium as well as inflammatory reaction by various substances from the outside and their metabolic products. Gastric mucosal lesions are proven to be associated with bacterial infection by the discovery of Heliobacter pylori(H. pylori) and many studies about histopathologic changes of gastric mucosa associated H. pylori infection has been advanced. It is known that H. pylori associated gastritis displays surface foveolar epithelial changes, such as cytoplasmic vacuolation, mucin loss, juxtaluminal cytoplasm erosion, epithelial denudation, and mucosal irregularity. There have been many studies that H. pylori infection is associated with intestinal metaplasia, gastric dysplasia, and carcinoma. Also chronic H. pylori infection with its induction of gastric lymphoid follicle has been implicated as a precursor of gastric lymphoma of the unique B-cell type that arises from mucosa-associated lymphoid tissue(MALT). However, these gastric mucosal changes are also observed in gastritis with other causes. In this study, we aimed to define specific histopathiologic findings associated with H. pylori infection. A total of 463 gastric biopsy specimens were reviewed. They were Helicobacter-associated gastritis and were divided as many (MH), a few (AH), and no (NH), according to the number of H. pylori. 210 (MH), 131 (AH), and 122 (NH) biopsy specimens were included. Lymphocytes, plasma cells in lamina propria, eosinophils and neutrophils in surface epithelium and crypt as well as lamina propria were graded from 0 to 3. Surface epithelial changes including cytoplasmic vacuolation, mucin loss, juxtaluminal erosion, epithelial denudation and mucosal irregrarity were observed in 200 of 210 cases(95%) in MH group, 34 of 131 cases(26%) in AH group, and 6 of 122 cases(5%) in NH group. This result indicates there is significant difference in surface epithelial changes according to the number of H. pylori(p<0.001). Severity of eosinophil, neutrophil, lymphocyte, and plasma cell infiltration is increased in proportion to the number of H. pylori. Especially, neutrophilic infiltration is not identified in 95 of 122 cases(78%) in NH group, whereas MH group shows severe infitration (grade 3) in 127 of 210 cases(61%), and no (grade 0) in 11 of 210 cases(5%). This data well explains that the severity of neutrophil infiltration is associated with, the degree of H. pylori infection in chronic active gastritis, with statistical significance. The prevalence of lymphoid follicle formation was 17 of 120 cases(14%) in NH group, 24 of 131 cases(18%) in AH group, and 52 of 210 cases(25%) in MH group. This shows that lymphoid follicle formation correlates with the number of H. pylori, but without statistical significance. The prevalence of intestinal metaplasia in NH, AH, and MH was 43 of 122 cases(35%), 46 of 131 cases(35%), and 69 of 210 cases(33%), showing no association between intestinal metaplasia and H. pylori. In summary, H. pylori associated gastritis dispays characteristic histopathological changes in gastric mucosa, in which surface epithelial changes and various inflammatory infiltrates are increased in proportion to the number of H. pylori. Especially vacuolization of surface foveolar epithelium, cryptitis, and crypt abscess are specific findings of H. pylori associated gastritis.

A few cases of reticulate acropigmentary disorders have been reported in Korea. Most of them were reticulate acropigmentation of Kitamura, but not acropigmentation symmetrica of Dohi. A 21 year-old male patient diagnosed as acropigmentation symmetrica of Dohi had been previously treated with various treatment methods unsuccessfully. Re-treatment with the Q-switched alexandrite laser(755 nm, 100nsec) showed a temporary improvement but a relapse of the lesion was experienced again. We describe a case of acropigmentation symmetrica of hi treated with the Q-switched alexandrite laser.
