PURPOSE: It is well known that linear growth in diabetic children is closely related to metabolic control and age of onset. Some studies showed growth retardation in diabetic children regardless of the degree of metabolic control, whereas others reported no growth impairment. Until now, no study has been done comparing linear growth between type 1 and type 2 diabetic children. Therefore, we compared the growth and weight status between type 1 and type 2 diabetic children. METHODS: 145 children with type 1 DM and 27 patients with type 2 DM were studied. Their growth status in height standard deviation score(HTSDS), obesity according to standard weight for height and body mass index(BMI), and HbA1c level at onset, 6 months, 1 year, 3 years and 5 years after treatment were compared. RESULTS: There was no distinct correlation in HTSDS in type 1 and type 2 DM, but in type 2 DM obesity according to standard weight for height and BMI was higher than in type 1 DM. deltaHTSDS 5 years after treatment of diabetic children with poor glycemic control were significantly decreased(P<0.05), but there was no significant correlation between HbA1c and obesity according to standard weight for height and BMI. CONCLUSION: There is no significant correlation between the type of diabetes and growth status, but the poor glycemic controled group showed a significant decrease in deltaHTSDS. These data suggest that the growth of diabetic children could be impaired in the case of poor glycemic control and long duration of diabetes.

BACKGROUND: Although drug eruption refers to a common dermatologieal condition, there are numerous setbacks in the diagnosis. In addition there are no annual average prevalence rates of drug eruptions according to time sequence in Korea. OBJECTIVE: This study attempts to detme the clinical features and causative drugs of drug eruptions, the diagnostic value of various skin tests and to evaluate the dome,stic annual average prevalence rate of drug eruptions according to time sequence. METHOD: 270 patients with drug eruptions were reviewed clinically. In 103 patients, intradennal, patch and scratch-patch tests were performed using suspected drugs. The annual average prevalence rate of drug eruptions was calculated from 10 different general hositals in Korea. RESULT: Exanthematous eruptions(49.3), fixed drug eruptions(30.1), and urticaria(10.0%) were the common types of drug eruptions. The common causative agents were antibiotics/antimicrobials, antipyretics(NSAIDs, and CNS depressants. 52 patients out of 103 had positive results after at least one skin test with suspected drugs. CONCLUSION: In our study, we were ahle to obtain somewhat meaningful results basnl on data from the combination of various skin tests. As a result, physicians need to prescrible drugs with care.

This study was designed to evaluate the expression of heat shock protein in tooth and surrounding tissue during the experimental movement of rat incisors, by LSAB(labelled streptavidine biotin) immunohistochemical staining for heat shock protein. Twenty seven Sprague-Dawley rats were divided into a control group(3 rats), and 6 experimental groups(24 rats), to which 75g of force was applied from helical springs across the maxillary incisors. Rats of experimental groups were sacrificed at 0.5, 1, 4, 7, 14 and 28 days after force application, respectively. And the periodontal tissues of a control group and experimental groups were studied immunohistochemically. The results were as follows : 1. In control group, the expression of HSP47 was rare in gingiva, dentin and cementum, and mild in periodontal ligament and alveolar bone. But it was more evident than that of HSP70. 2. The expression of HSP47 or HSP70 was rare or mild in dentin, cementum and odontoblast of experimental group, regardless of the duration of force application, which was not different from that of control group. 3. In experimental group, the expression of HSP47 got to the highest degree in periodontal ligament and alveolar bone at 4 days after force application, and then decreased. And the expression was more evident in the pressure side than in the tension side of periodontal ligament 4. The expression of HSP70 began to increase at 12 hours after force application and got to the highest degree at 4 days, in the capillary of pulp and periodontal ligament. And the expression was more evident in the pressure side than in the tension side of periodontal ligament 5. The expression of HSP70 in alveolar bone of experimental group was rare, which was similar to that of control group.

BACKGROUND: Recently, according to many studies, variable factors have been known to be associated with physical fitness. The factors such as obesity and inactivity are associated with poor physical fitness, but regular exercise is associated with good physical fitness. In our country, these studies are not yet reported. And so, this study was designed to investigate the factors associat,ed with physical fitness. METHODS: From May 1st, until July 30th 1996, we recruited the 411 subjects who visited the Health Promotion Center at Seoul National University Hospital. Data related to sex, age, exercise, job, cigarette smoking, alcohol consumption were obtained by self-administered Questionnaire. Obesity index was calculated by the percentage of standard body weight. And VO2max were obtained by submaximal bicycle ergometer test. High level exercise group was defined as the persons who had taken exercise more than 3 times a week and 20 minutes per session, and moderate exercise group was defined as the persons who had taken exercise one or two times a week and 20 minutes per session, and sedentary group was defined as the persons who had taken exercise more than 20 minutes less than one time per week. RESULTS: The subjects were 230 males(56%), total numbers were 411. The results were as follows. Compaired to women and nonexercise group, men and exercise group had high VO2max(p<0.005). The relationship between VO2max and age showed negative, and the VO2max of obese group(obesity index>_120) was greater than that of nonobese group. Any significant relationships between VO2max and job, disease were not found. In multiple regression analysis, significant relationships between VO2max and age, sex, exercise type, and obesity index were observed(p<0.01). CONCLUSIONS: We concluded that there were significant relationships between VO2max and obesity index, exercise group.

An outbreak of dermatosis occurred at a machinery manufacture factory in kyongju on Aug 1995. Authors conducted a questionnaire survey among 92 workers in the factory and a dermatologist examined their skin lesions. Authors also collected moths and identified them. The results are as follows; 1. Forty-two cases of dermatosis were identified with attack rate of 45.7%. Attack rate was not different by company, age, sex, educational level and duration of employment. Attack rate was 47.8% among productive workers, 25.0% among clerical workers and 100.0% among patrolmen. 2. Two cases among 42 dermatosis cases and three subjects among 50 non-cases had a history of same dermatosis last year. Four of dermatosis cases had a history of dermatosis among their family members. 3. skin lesions of the cases were scattered or grouped rice-sized erythematous papules or vesicles. Duration of dermatosis from the onset to the time of survey was from one day to more than 30 days. The most frequent site of skin lesion was the arms(81.0%), and it was also observed at the neck(47.6%), abdomen(45.2%), chest(42.9%), legs(38.1%) and back(35.7%). skin lesion was aggravated with sweating(31.0%), after shower(16.7%) and with scratching(l1.9%). 4. Moths were collected and identified as Euproetis subflava(Bremer). Many poisons stings were observed on their wngs which is harmful to human. 5. Contact with moths' wing droppings to two authors on their forearms for provocation resulted in severe immediate pain followed by prolonged pruritus. Erythematous macules quickly appeared and suoceeded by firm wheal-like red papules. Authors thought that the outbreak of dermatosis was brought about by Euproetix subflava(Bremer). Further studies on the factors contributing to the prosperity of the moths in this area are needed.

BACKGROUND: Acromioclavicular (AC) stability is maintained through a complex combination of soft-tissue restraints that include coracoclavicular (CC), AC ligament and overlying muscles. Among these structures, the role of the CC ligament has continued to be studied because of its importance on shoulder kinematics, especially after AC injury. This study was designed to determine the geometric change of conoid and trapezoid ligaments and resulting stresses on these ligaments according to various scapular motions. METHODS: The scapuloclavicular (SC) complex was isolated from a fresh-frozen cadaver by removing all soft tissues except the AC and CC ligaments. The anatomically aligned SC complex was then scanned with a high-resolution computed tomography scanner into 0.6-mm slices. The Finite element model of the SC complex was obtained and used for calculating the stress on different parts of the CC ligaments with simulated movements of the scapula. RESULTS: Average stress on the conoid ligament during anterior tilt, internal rotation, and scapular protraction was higher, whereas the stress on the trapezoid ligament was more prominent during posterior tilt, external rotation, and retraction. CONCLUSIONS: We conclude that CC ligament plays an integral role in regulating horizontal SC motion as well as complex motions indicated by increased stress over the ligament with an incremental scapular position change. The conoid ligament is the key structure restraining scapular protraction that might occur in high-grade AC dislocation. Hence in CC ligament reconstructions involving only single bundle, every attempt must be made to reconstruct conoid part of CC ligament as anatomically as possible.

Normal lymphocyte transfer (NLT) test is composed of two peaks of delaycd. hypersensitivity reaction of erythema and/or induration developed at the site of intradermal inoculatioa of allogenic lymphocyte. It has been suggested that NLT test is a px.siblc homograft raaction, how var tlv exact mecha.nism is remained to be resolved. In leprosy, there has been accumulating evidenc. indicating defective cell mediated. immunity detected by varioua immunological tests. The present study was undertaken to evaluate the immune capability of patients with leprosy using NLT test. A total of 20 hea,lthy volunteers, 20 lepromatous and 22 tuberculoid leprosy patients who were under antileprosy chemotherapy with DDS for varying periods, entered this study. Lymphocytes from hepatitis associati antigen (HAA) negative donor were isolated with Ficoll- Hypaque density gradient method and the cell concentration was adjusted by normal saline so as to give 2, 5 million cells per 0. 1 ml. Each recipient was given 0. 1 ml lymphocyte suspension on the flexor surface of th right forearm intrad.ermally using 1 ml tuberculi n syringe with a 26 gauge needle. The appearance and the size of induration was checked daily for 2 weeks. In this atudy, the NLT reaction pattem was classified as follows: a. normal pattem showing the first peak and second peak of reaction. b. first peak only showing the first peak, but no second peak, of reaction. c. flat pattem showing neitger the first peak nor the second peak of reaction The results were as follows: 1. There were normal pattem in sixteen persons(80%) and first peak only in 4 persons(20%) among twenty healthy human volunteers. 2. There were normal pattem in four patients(20%), first peak only in six patients(30%) and flat pattem in ten patients(50%) among twenty letromatous leprosy patients. 3. There were normal pattem in twelve patients(54.5%), first peak only in eight patients(36.4%) and flat pattem in two patients(9.1%) among twenty-two tuberouloid leprosy patients. These findings suggest that NLT test may be useful in evaluating the immune capability in leprosy and host factor in belived to be important in the development of both first and second peaks of NLT test.

OBJECTIVE: To evaluate the effect of Mcdonald's cerclage and postoperative care on perinatal outcome in patient with incompetent cervix and bulging fetal membranes. METHODS: In the descriptive study, the charts of 78 patients admitted from 1993 to 1997 with a diagnosis of incompetent cervix and cervical dilatation (3cm) were reviewed, Mcdonald's cerclage rate, predisposing factor, fetal salvage by time, factors of falled operation, delivery type were analyzed. RESULTS: The results of the study were as follows; The incidence of II OC was 0.4% of 18702 case, the mean age was 31.9 years old, the average number of gravida was 2.9, the fetal salvage rate was 83.3%, the predisposing factor was previous history of midtrimester termination(56.4%), dilation and curettage(19.2%), unknown(14.1%) etc, the fetal salvage by time was the highest success rate(88.9%) revealed with period from 14th to 16th weeks of gestation, the factors of falled operation were preterm labor(76.9%), PROM(15.4%), infection(7.7%), and delivery type was vaginal delivery in 36 case(55.4%), cesarean section in 29 case(44.6%). CONCLUSION: We concluded that fetal salvage rate was greatly increased when Mcdonald operation was done from 14th to 16th week of gestation if midtrimester abortion and dilatation and curettage were experienced, Even though we have not compared experimental group with control group, upper part of Mcdonald cerclage, no exposure of suture material, benzol conium dressing, bed rest were increased to fetal salvage rate.
