1.Two Cases of Mercury Exanthem.
Korean Journal of Dermatology 1987;25(2):240-244
We herein report two cases of systemic contact dermatitis probably due to inhalation of mercury. The first case is a 13 year-old boy who developed generalized erythema and dyspnea following the use of a coin-bleaching solution of unknown ingredient in his room. And the second case is a 10 year-old boy who developed generalized scarlatiniform eruptions on his trunk and flexural aspect of his extremities after hreaking a clinical thermometer. The typical clinical feature, the inverted triangular shaped erythema on flexural aspect of inner thigh, were appeared in both patients. On patch testing, they showed positive reactions to mercury and other mercury compounds.

2.Experimental Induction of Pancreatic Hyperplastic Nodules by Administration of 4-hydroxyaminoquinoline-1-oxide in Rats.
Korean Journal of Pathology 1986;20(2):133-146
Pancreatic hyperplastic nodules were experimentally produced in male Sprague-Dawley rats by single doses of intravenous injection of 4-hydroxyaminoquinoline-1-oxide(4-HAQO), 5 mg, 10 mg, 20 mg and 30 mg per 1kg of body weight. Every ten rats were sacrificed after 1 day, 1 week and monthly until 6 months. Within the first week, pancreatic acini and islets were severely affected with necrosis and the adjacent acinar cells underwent vacuolization. But, pancreatic ductules remained relatively unaffected. The degrees of acinar cell degeneration were proportionally increased as with the increased doses of 4-HAQO administration. The levels of blood glucose and serum amylase were closely corresponding to the light microscopic features of the pancreas. Two months after administration of 4-HAQO, the nongranular acinar cells started to proliferate and their proportion of total acinar cells was 35%, whereas that of control group was 15%, after 3 months the proportion of nongranular cells was decreased. After 6 months, multiple hyperplastic nodules were discovered within the pancreatic acini of all 12 rats, and the largest one measured 500 micro in diameter. Each hyperplastic nodule was uniformly composed of larger cells in two folds of normal cells with hyperchromatic muclei and prominent nucleoli together with a few zymogen granules in their cytoplasms. Ultrastructurally, the cells contained abundant dilated endoplasmic reticulum and markedly decreased zymogen granules. Nuclear heterochromatin became finely dispersed with loss of marginal clumping. During the regeneration process, admixture of islet cells with membrance-bounded granules was identified among the clusters of regenerating acinar cells. On the basis of above findings, the induction of hyperplastic nodules in rat pancreas by 4-HAQO was confirmed, and its histogenesis may reflect a nodular hyperplasia of non-granular acinar cells with potential progress as a neoplastic lesion. And the evidence of the hypothesis that the pancreatic exocrine cells and endocrine cells are in same origin, was presented.

A 72-year-old woman with a pea sized, bluish, firm nodule was diagnosed as having a cellular type of dermatofibroma histopathologically. A biopsy specimen revealed a relatively well circumscribed, non-encapsulated, nodular infiltration of irregularly distributed histiocytes in the deep dermis. Foam cells were also noted. Gomoris iron stain revealed large amounts of hemosiderin deposits and some collagen were present as individual fibers in the lesion with Masson's trichrome stain.

Two cases of malignant histiocytosis, in which skin involvement was a prominent finding at initial clinical presentation, are reported. 1nteresting histopathologic findings, including Langerhans granule in one case and numerous eosinophils in another, were observed. In one case remission was achieved with BACOP chemotherapy (Bleomycin, Adriamycin, Cyclophosphamide, Vincristine, and Prednisone). In the other case, the patient died nine months after the onset of the disease without any treatment.

6.A Study of the Effectiveness of Token Economy on Children's Behaviors for Oral Medication.
Korean Journal of Child Health Nursing 1999;5(3):318-328
Oral medication is one of the most frequent treatment in clinical care, and frequently refused by children. Children's refusal spends unuseful time and require nurses' patience. So this study was attempted to develop token economy program which promote children's medication, and to evaluate its' effect to construct the experimental ground. This study was a quasi experimental study under the nonequivalent control group non-synchronized design. The subjects of this study were 48 children who were aged 3-12 years and admitted pediatric ward because of their respiratory disease. Token economy program was consisted of cartoon record paper with stickers which expresses the better medication is taken the more germs die, and gift was given for back up reinforcer. To evaluate this program, time spent for oral medication was measured six time to both experimental group and control group, and measured the perceived effectiveness of this program by nurses. To determine the effect of the program, the data were analyzed by the SAS 6.12 program with t-test and mean, standard deviation. The results of this study were as follows: 1. In experimental group, time spent for oral medication was significantly shorter than in control group(t=5.24, p=0.0001). Therefore, the hypothesis of this study was strongly accepted. 2. Nurses perceived this program as an effective one(mean=3.125 ~ 3.792). The effectiveness occurred before, during and after medication as well as in parental responses, especially in using verbal dissatisfaction after medication. In conclusion, it was found that the token economy program for admitted children was effective in inducing the children's behavior of oral medication. There was no effectiveness in very highly anxious children. Whereas, it is recommended that this program should not be used for such children until they settle down. If the token economy program was made in various situation with creative thinking, it will be very useful nursing measurement, especially in caring for children. To improve the quality of nursing care, the various programs, which can give joyfulness to stressed patients should be developed.

INTRODUCTION: It has been proposed that narcolepsy and REM sleep behavior disorder (RBD) have overlapped symptom profile and pathophysiology. This study was aimed at measuring and comparing changes in EEG frequency band of REM sleep in narcolepsy and RBD, applying EEG spectral analysis method. METHODS: Nine patients diagnosed as narcolepsy and the same number of RBD patients were studied. Spectral analysis of the REM sleep EEG was performed in each patient on 9 epochs selected evenly from the first, second, and third REM periods. Then, we compared frequency band percentages of REM sleep EEG in narcolepsy and RBD. RESULTS: Narcolepsy patients had significantly higher delta frequency ratio than RBD ones (p=0.00). In alpha and beta2 frequency bands, RBD patients showed higher percentage than narcolepsy ones. Slow wave sleep was more prevalent in narcolepsy patients. But, no difference of REM sleep percentage was found between the two groups (p=0.93). CONCLUSION: Higher delta frequency ratio in REM sleep of narcolepsy patients than RBD ones reflects that sleep-promoting mechanism is more dominant in narcolepsy than in RBD.

A 45 year old male patient complained of mucous fluid drainage in the vicinity af the manubrium sterni for 5 years. Skin around the lesion had normal appearance except pinpoint sized sinus opening. H.istopathology showed a cyst in the upper and mid-dermis which consisted of pseudoetratified columnar epithelium with interspersed goblet cells. Goblet; cells were confirmed by positive stain to D-PAS and alcian blue and by metachromatic stain to toluidine blue. VFe present here a case of cutaneous bronchogenic cyst clinically and histopathologically which is thought to be the first cace in Korea.

Treatment of chronic localized osteomyelitis is the same as the other osteomyelitis, that is, curettage and debridement of all dead tissue which is called saucerization. After saucerization there leaves empty cavity and autogenous bone graft has been used for filling the cavity in lower extremity hecause of weight bearing and avoiding fracture. We treated seven cases of chronic localized osteomyelitis with one-staged saucerization and cancellous chip allograft and retrospective analysis was done. All healed without complication and no recurrence was ohserved. Most orthopaedic surgeons are not willing to use allograft on the site of osteomyelitis because of the fear of recurrence. But. we think that as far as complete removal of infected and dead tissue, allograft could he a good solution in terms of rapid remodelling and early weight hearing. Another advantages of allograft are to get a large amount of bone and no damage of iliac apophysis. In summary, one-staged saucerization and cancellous chip allograft would he very useful treatment for chronic localized osteomyelitis.

10.A study of correlation on the skeletal factors of the anterior open bite.
Korean Journal of Orthodontics 1985;15(2):249-260
To analyze the skeletal characteristics of the open bite, the faces of normal occlusion and open bite were measured using a cephalogram. The factors which were greatly different form normal occlusion were selected. The effects of these factors on the incisal overbite and correlation on these factors were studied. The following results were obtained. 1. The 13 factors which comprised the characteristics of the open bite were obtained. (Table 5) 2. The cause and amount of the open bite were dependent on the skeletal angulation than skeletal length. 3. For determining the incisal overbite, most highly correlated sigle factor was the interincisal angle. 4. The correlation on the selected 13 factors which comprised the characteristics of the open bite was obtained. (Table 6) 5. The open bite was due to combination of various factors than due to single factor. (Table 3,4)
