We describe S100 protein positive dendritic cells (S100+DCs) in various liver diseases including chronic viral hepatitis B and C (20 cases), liver cirrhosis (3 cases), hepatocellular carcinoma (2 cases), hepatolithiasis (6 cases), primary biliary cirrhosis (PBC) (2 cases), liver allograft rejection (9 cases), bile duct paucity (1 case), and Wilson's disease (1 case). By immunohistochemical analysis, S100+DCs were absent in fetal and normal livers, while they were variably present in inflammatory liver diseases. In chronic hepatitis and active cirrhosis, S100+DCs were most frequently located in periportal area, at lymphoid follicles within the portal tract, and at foci of spotty necrosis within the lobule. Frequency and intensity of S100+DCs were not related to etiologies of liver diseases, but they were correlated with the activity of hepatitis. In PBC, S100+DCs were found between biliary epithelial cells of the septal bile ducts, as well as, the periductal area of the portal tracts. A posttransplantation liver with features of moderate acute rejection revealed many S100+DCs in polymorphous portal infiltrates. In hepatocellular carcinomas, many S100+DCs were scattered between tumor cells. In the case of the Wilson's disease, S100+DCs were not noted. Presence of S100+DCs in various inflammatory liver diseases indicates that they play a central role as antigen presenting cells in immune responses of inflammatory liver diseases.

2.Increased expression of the c-fos and c-myc oncogenes in psoriatic lesions.
Korean Journal of Dermatology 1991;29(3):331-336
The expression of the c-fos and c-myc oncogenes was investigated by dot blot analysis of total RNA extracted from biopsies of normal skin and psoriatic lesions. Densitometric analysis revealed 6.3 fold and 8.6 fold evevation respectively of c-fos and c-myc oncogenes mRNA levels in severe psoriasis compared to normal skin, and 1.5 fold and 1.6 fold elevation respectively of c-fos and c-myc oncogenes mRNA levels in mild psoriasis compared to normal skin. The ratio of c-fos/c-myc transcripts in normal skin and mild psoriasis was constant compared to that in severe psoriasis. The maintenance of a constant ratio of c-fos/c-myc is believed to be closely related to ordered cell growth and the ratio of c-fos/c-myc transcripts in severe psoriasis suggests a disordered pattern of cellular differentiation. We be1ieve that overexpression of these oncogenes is related to the pathogenesis of psoriatic epidermal hyperplasia.

OBJECTIVES: Depression, sleep complaints and cognitive impairments are commonly observed in the elderly. Elderly subjects with depressive symptoms have been found to show both poor cognitive performances and sleep disturbances. However, the relationship between sleep complaints and cognitive dysfunction in elderly depression is not clear. The aim of this study is to identify the association between sleep disturbances and cognitive decline in late-life depression. METHODS: A total of 282 elderly people who underwent nocturnal polysomnography in a sleep laboratory were enrolled in the study. The Korean version of the Neuropsychological Assessment Battery developed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was applied to evaluate cognitive function. Depressive symptoms were assessed with the geriatric depression scale (GDS) and subjective sleep quality was measured using the Pittsburg sleep quality index (PSQI). RESULTS: The control group (GDS< or =9) when compared with mild (10< or =GDS< or =16) and severe (17< or =GDS) depression groups, had significantly different scores in the Trail making test part B (TMT-B), Benton visual retention test part A (BVRT-A), and Stroop color and word test (SCWT)(all tests p<0.05). The PSQI score, REM sleep duration, apnea-hypopnea index and oxygen desaturation index were significantly different across the three groups (all indices, p<0.05). A stepwise multiple regression model showed that educational level, age and GDS score were predictive for both TMT-B time (adjusted R2=35.6%, p<0.001) and BVRT-A score (adjusted R2=28.3%, p<0.001). SCWT score was predicted by educational level, age, apnea-hypopnea index (AHI) and GDS score (adjusted R2=20.6%, p<0.001). Poor sleep quality and sleep structure alterations observed in depression did not have any significant effects on cognitive deterioration. CONCLUSION: Older adults with depressive symptoms showed mild sleep alterations and poor cognitive performances. However, we found no association between sleep disturbances (except sleep apnea) and cognitive difficulties in elderly subjects with depressive symptoms. It is possible that the impact of sleep disruptions on cognitive abilities was hindered by the confounding effect of age, education and depressive symptoms.

BACKGROUND: We compared factors associated with self-reported depression and, in particular, diagnosis and treatment of depressive symptoms in Korean adults. METHODS: The sample included 13,306 adults aged 19 years or older from the 2010 and 2011 Korea National Health and Nutrition Examination Survey (KNHANES V). Data were applied to the chi2 test and multivariate logistic regression analysis. RESULTS: The following characteristics of individuals are significantly associated with self-reported depression: female (vs. male, OR [odds ratio]=3.35), ages 50-59 years (vs. 60+, OR=1.45), economic status (low vs. high, OR=1.35; middle-low vs. high OR=1.29), unemployed (vs. employed, OR=1.23), education (elementary vs. college, OR=1.18; middle school vs. college, OR=1.27; vs. high school vs. college, OR=1.18), current smoking (vs. no, OR=1.19), high-risk alcohol consumption (vs. no, OR=1.18), perceived health (good vs. very good/excellent, OR=1.156; poor/fair vs. very good/excellent, OR=2.65), chronic disease (vs. no, OR=1.26), activity limitation due to health problems (vs. no, OR=1.74), and being in a sickbed during the past month (vs. not in a sickbed, OR=1.69). Living in a metropolitan area (vs. rural, OR=1.40) is significantly associated with greater odds of being diagnosed with depression. The odds of being treated for depression are lower for female (vs. male, OR=0.53). Greater odds of being treated for depression was seen for those with chronic conditions (vs. no, OR=1.73) and activity limitation due to health problems (vs. no, OR=2.05), as well as, those in a sickbed (vs. not, OR=1.88). CONCLUSIONS: Applying our findings, policy makers should address the lower rates of depression diagnosed in non-metropolitan areas to reduce regional variations, and also promote treatment in females.

Eccrine spiradenoma is clinically characterized by a solitary, movable, tender nodule occurring most frequently on the ventral surface of the upper body. A striking symptom is paroxysmal pain. Occasionally multiple lesions may be present and may occur in a linear or zosteriform pattern. A 48-year-old female was seen with painful or tender, nomal skin colored, firm nodules distributed in a zosteriform pattern on the right thigh for 10 years, which had been slowly growing. The histopathological features were quite a characteristic of eccrine spiradenoma. We report a rare case of zosteriform network of eccrine spwadenoma occurred on the right thigh.

This study was performed by the necessity of objective information upon change of pulmonary function after surgical correction of spinal deformity in scoliotic patients. It is relatively well known that deformity of spinal curvature affects the pulmonary functions, especially lung volume or vital capacity, due to restriction of the thoracic cage. It is carried out the comparative study between preoperative and postoperative pulmonary functions in thirty two cases of thoracic scoliosis, all who were treated with Harrington instrumentation and posterior fusion at Department of Orthopedic Surgery, Seoul, National University Hospital from 1969 to 1983. The age distribution of patients was from 6 years to 21 years and female was more involved two times than male. Following observations were obtained: Following observations were obtained: 1. Pre-and postoperative angle of scoliosis were 77.5° and 39.2° with correction rate of 48.2%. 2. Preoperative vital capacity was 64.2% and postoperative value was 74.8%, 2 years and 2 months after operation in average. 3. Postoperative vital capacity was significantly increased compared to preoperative value in patients with scoliosis (p<0.05). 4. Ther was no definite pattern of obstructive pulmonary disease in patients with scoliotic deformity.

The Journal of the Korean Orthopaedic Association 1986;21(3):415-421
Zielke introduced new anterior instrumentation by modifying Dwyer system and called it the ventral derotation spondylodesis(VDS) system in 1976. This system is a powerful device and when the excised disc spaces are compressed with it, stable fixation can be obtained. But proper patient selection, meticulous operative technique and good post-operative care are essential to minimize serious complications. No results of this technique had been published in English-language literature until Moe reported the results of 66 cases of Zielke instrumentation in 1983. Zielke instrumentation was carried out in 12 cases of scoliosis;8 in idiopathic scoliosis and 4 in congenital scoliosis, at the Department of Orthopedic Surgery, Seoul National University Hospital, for 16 months from November 1984 to March 1986. Seven cases had been followed for more then 9 months and'following results were obtained. 1. Numbers of vertebrae involved in major curve and numbers of fused vertebrae were 6·3 respectively. 2. Average preoperative curve was 72.7 degrees and immediate postoperative curve was 17.6 degrees with 75.8% correction. There was only 1.0 degree loss of correction with an average follow-up of 14 months (9-16 months). 3. Zielke instrumentation has the advantage of shorter fusion and better correction in thoracolumbar and lumbar scoliosis.

Common peroneal nerve injury has been reported as the most frequent lower extremity peripheral nerve injury. The peroneal nerve may be particulary prone to direct or indirect injury by penetrating trauma or external compression by it's superficial route to bony prominence of fibular neck. By the development of microsurgical technique, recently epineural repair, fascicular group repair, and interfascicular graft were tried. The authors have experienced five cases microsurgical repair of common peroneal nerve injury around the knee joint from December 1990 to November 1991, and motor and sensory result was relatively good.
