BACKGROUND: Many mammals normally have a population of dermal melanocytes but these are not found in man, In humans, persistent dermal melanocytes can occur in the Mongolian spot, the nevus of Ota, and the blue nevus. Mongolian spot develops in the fetal or neonatal time and disapperars almost invariably during childhood. In contrast, nevus of Ota and blue nevus are not usually present at birth and persists in adult life. Recently, it was established that apoptosis can be involved in the development of melanocytes. The integrins mediate cell-cell and cell-matrix interactions, and apoptosis can be induced by disruption of cell-matrix interactions. OBJECTIVE: The purpose of this study was to investigate the expression of integrins (a2, a3, ar) and in situ detection of fragmented DNA in Mongolian spot, nevus of Ota, and blue nevus. METHODS: Formalin-fixed and paraffin-embedded tissues from 8 cases of Monglian spot, 5 cases of nevus of Ota, and 4 cases of blue nevus were immunolabelled with monoclonal antibodies TM directed against az, ay, and av integrin, and stained with ApopTag in situ using an Apoptosis Detection kit. The cases of Mongolian spot were divided into two groups in which group A represented the the cases of more than 45 melanocytes and group B represented the cases of less than 10 melanocytes in a tissue section of 4-mm taken from punch biopsy specimens. RESULTS: Blue nevi showed az and e integrin expressions in dermal melanocytes and weak to negative staining of g v integrin in comparison with all positive expressions of a z, a s, and g y integrin in A group-Mongolian spots and nevi of Ota. The B group-Mongo]ian spots showed the continuous expressions of a z and a y integrin with negative expressions of a v integrin. The ApopTag kit staining was all negative in the Mongolian spots, nevi of Ota, and blue nevi. CONCLUSION: Our results support the view that dermal melanocytic tumors, such as the Mongolian spot, the nevus of Ota, and the blue nevus, might be induced by the disturbance or inhibition of the apoptotic process of the melanocytes, and that the spontaneous disappearance of the Mongolian spot may not be related to the apoptosis.

The femur is the largest long bone in the body which is related to weight bearing. As a result of rapid increase in traffic accidents and industrial injuries, the incidence of femoral shaft fractures has risen also. The methods of treatment in children and adults are different, therefore inadequate treatment can cause permanent disability. The authors have reviewed 211 cases of femoral shaft fractures in 204 persons (children and adults) from September 1967 to September 1976 whe were admitted and treated in Orthopedic Department, Severance Hospital. The results were as follows: 1. The fractures occured commonly in the 6–10 yr. age group (41.2%) in children and in the 21–40 yr. group (54.2%) in adults. Males comprised 138 cases (67.6%). 2. Closed fractures were 185 cases (87.7%) and comminuted fractures were the most common type, 94 cases (44.5%) in all. The fracture site was middle third in 116 cases (55%). 3. Causes were mainly car accidents, 146 cases (71.5%) and industrial injuries. Pedestrian injuries are particularly common in Korea. Many industrial accidents occur due to inadequate working facilities in factories. 4. Associated injuries were common in young adults and in order of frequency these were fractures of the tibia and fibula; skulls; pubic bone. 5. In the early and delayed operation groups, primary bony union rate was better (92%) in the early than the late operation group (78.3%). 6 The period of bony union was 13 weeks with compression plate and screw fixation: 16 weeks with Kuntscher nailing; 17. 5 weeks with plate and screw fixation; and 20 weeks with skeletal traction in adults. 7. Knee joint motion was most limited with skeletal traction (33.5%), less with plate and screw fixation (14.7%) and Kuntscher nailing (1.7%), but none with compression plate and screw fixation. 8. Good results were obtained with conservative treatment in children and operative treatment in adults. 9. Complications were much less frequent in children than in adults and were treated well. 10. Post-operative infection rate was 4.4% and infection was treated well with conservative measures. 11. The 90° – 90° skeletal traction in children and compression plate and screw fixation along with cast brace in adults were recommended.

Twenty-two cases of idiopathic myocardiopathy were observed during the period of 1962 to 1971 and follow up clinical study was made in 5 cases. The criteria of diagnosis was based mainly on exclusive diagnosis in etiology unknown marked cardiomegaly. 1) Male and female ratio of idiopathic myocardiopathy was 1.1:1 and age of onset were distributed from first decade to fifth decade with similar number of cases. 2) Cardinal symptoms were dyspnea, palpitation, chest pain and cough. Common physical findings were protodiastolic gallop (in 2 cases), moist rales (in 3 cases) and hepatomegaly(in 3 cases). 3) Laboratory findings were normal except elevated T.T.T. in one case. 4) Electrocardiogram were abnormal in all cases. There were 3 cases of left ventricular hypertrophy, 3 cases of non-specific ST-T changes and one case of first degree A-V block, intraventricular conduction defect, abnormal Q wave and low valtage, respectively. 5) After medical treatment, symptoms were improved in 4 cases but heart size was reduced in only one case and E.C.G. abnormalities were unchanged in all cases.

OBJECTIVE: To evaluate the basophil histamine releasability in response to IgE- and non- IgE-mediated stimuli in children with atopic asthma. Met: Basophil histamine releasability was measured in Dermatophagoides farinae (D. farinae)-sensitive atopic asthmatics, D.farinae-sensitive healthy atopics, non-atopic asthmatics, and healthy non-atopics. Basophils were stimulated with D.farinae, goat antihuman IgE antibody, formyl-Met-Leu-Phe(fMLP), and Calcium ionophore A23187. Histamine was measured by automated fluorometric technique. RESULTS: Sponianeous histamine release was higher in atopic asthmatics compared to healthy non-atopics. Histamine release by D.farinae and by anti-IgE antibody was higher in atopic asthmatics compared to the other groups. There was no difference in histamine release by fMLP among all groups. Histamine release by Calcium ionophore was higher in healthy atopics and non-atopic asthmatics compared to healthy non-atopics. The atopics showed correlation between histamine release by D.farinae, by anti-IgE antibody and total serum IgE levels. CONCLUSIONS: Spontaneous and IgE-mediated histamine release were related to the presence of both atopy and asthma, whereas non-IgE mediated histamine release was different depending on the stimuli.

Bone marrow transplantation has become an accepted treatment for malignancy(particulary leukemia and lymphoma), aplastic anemia, and certain inborn errors of metabolism. In addition to the problem of severe, prolonged myelosuppression, bone marrow transplantation is associated with several unusual complications. Among the complications such as GVHD, graft rejection, interstitial pneumonia and veno-occlusive disease, involvement of the gastrointestinal tract by GVHD is associated with high graft failure and mortality. Intestinal GVHD is usually manifest clinically as voluminous secretory diarrhea accompanied by abdominal cramping, ileus, nutritional depletion, and, at times, hemorrhage. We experienced a case of severe intestinal GVHD after allogeneic marrow transplantation for treatment of severe aplastic anemia. He received bone marrow from his elder sister, HLA-matched multiparous woman and suffered from large amount of watery diarrhea with skin rash 34 days after transplantation. 1n spite of prednisolone therapy the symptom was progressed. After sigmoidoscopic mucosal biopsy, intestinal GVHD was confirmed and we tried methylprednisolone pulse therapy. Skin lesion was improved but the amount of diarrhea was increased with intermittent abdominal cramping. We tried ALG(anti-lymphocyte globulin) and conservative management but the patient did not respond the therapy. He succumbed to pneumonia and acute respiratory insufficiency complicated with GVHD, 70days after transplantation.

Malignant histiocytosis is a rare, usually fatal malignant neoplasm of reticuloendothelial systems. The disease is associated with fever, malaise, weight loss, hepatosplenomegaly, lymphadenopathy, pancytopenia, jaundice, and purpura. A 44-year-old female patient is described who had multiple, purple crusted nodules and plaques in the skin. In the laboratory study, pancytopenia was noted on the peripheral blood. In addition many atypical histiocytes were seen on the bone marrow aspiration. A lesional biopsy showed nodular infiltrations of atypical histiocytes in the dermis and some erythrophagocytosis was seen. Immunohistochemically, the histiocytes were weakly stained for lysozyme and α-l-antichymotrypsin, but were unstained for S-100 protein, cytokeratin, CEA(carcinoembryonic antigen), pan T/B marker CD30(ki-1), UCHL-1 LCA(leukocyte common antigen), and α-l-antitrypsin.

Radiation treatment results were analyzed in a retrospective analysis of 47 patients with pituitary adenoma treated with radiation alone or combined with surgery from 1974 through 1987 at the Department of Therapeutic Radiology of Kyung Hee University. The 5-year overall survival rates for all patients was 80.4%. Radiation therapy was effective for improving visual symptoms and headache, but could not normalize amenorrhea and galactorrhea. There was no difference of survival rate between radiation alone and combination with surgery. Prognostic factors such as age, sex, disease type, visual field, headache and surgical treatment were statistically no significant in survival rates of these patients.

Forty-four patients with brain astrocytoma and glioblastoma were treated with surgical resection and postoperative radiation from January 1980 through May 1987. Four patients were lost to follow up, and in 40 patients sruvival time was evaluable. Three year actuarial sruvival rate was 66.7% in Grade I and II astrocytoma, 30% in Grade III, and 20.4% in glioblastoma multiforme patients. The prognostic factors affecting survival rate were histologic grade in all cases, age, and total radiation dose in Grade III and glioblastoma.

PURPOSE: This study was conducted to provide basic data necessary to develop a program to improve infection control by examining nurses' perception of accreditation and by identifying its relationship with awareness and performance of infection control. METHODS: This cross-sectional study was performed using questionnaires. Data were collected from 210 nurses who were working at one hospital between May 14 and May 19, 2015. Data were analyzed using SPAW. RESULTS: The mean score for nurses' perception of accreditation was 3.10 points out of 5 points. Score for awareness of infection control was 4.63±0.39 points and for performance of infection control, 4.39±0.39 points. There were significant positive correlation among perception of accreditation, awareness of infection control, and performance of infection control. In the regression analysis, performance of infection control was influenced by awareness of infection control which accounted for 42.6% of the variance. It also showed additional improvement of 1.4% of the variance by when perception of accreditation was added. CONCLUSION: The result of this study show that nurses' perception of accreditation is relatively positive and that performance of infection control is highly enhanced according to nurses' positive recognition of accreditation as well as attaching importance to accreditation.
