Thirty one infants of diabetic mothers(IDM) who had been admitted in Neonatal Intensive Care Unit at Chonnam University Hospital from January 1987 to July 1991 were studied for evaluation of their perinatal outcome and prognosis. The results were as follows; 1) The distribution of diabetic mothers according to modified White's classification was GD & class A in 12 cases(38.7%), B in 16 cases(51.6%), C in one case, D4 in one case, and R in one case. 2) Of the 31 diabetic mothers, 8(25.8%) had a history of infertility or stillbirth, 20(64.5%) had prognostically bad signs of pregnancy (PBSP), and 12(38.7%) were treated with insulin and/or oral hypoglycemic agent during pregnancy. 3) C-section rate was 32.2%, and the rates of shoulder dystocia and birth asphyxia were 35.5% and 29.0%, respectively. 4) The rates of large for gestational age were 75.0% in class GD & A, 68.8% in class B, and the rates of small for gestational age were 8.3% and, 6.3% respectively, Characteristic face with body composition was noted in all babies, hepatosplenomegaly in 90.3%, heart murmur in 41.9%, respiratory distress syndrome in 12.9%, transient tachypnea of mewborn in 19.4%, hypertrophic cardiomyopathy in 40.0%, and seizure in 6.5%. 5) Laboratory abnormalities were hypoglycemia in 77.4%, hyperbilirubinemia in 83.9%, polycythemia in 16.1%, hyperinsulinemia in 45.5%, hypercalcemia in 22.6%, and hypomagnesemia in 23.1%. 6) Birth injuries were noted in 61.3%, The most common were caput succedaneum and/or cephal-hematoma, brachial palsy, and fracture. Congenital anomalies were noted in 16.1%. The most common were musculoskeletal, cardiovascular, and gastrointestinal anomalies. 7) In the short term follow up of 19 patients, there were mild developmental delay in 2 cases, cerebral palsy in 2 cases, and epilepsy in 1 case. These results suggested that infants of diabetic mothers had greater morbidity than infants of nondiabetic mothers. Therefore, long term follow up is recommended to achieve their normal growth and development.

PURPOSE: This study was done to explore life stress and coping skills of boarding high school students. METHODS: Triangulation (quantitative and qualitative) research method was used through three stages. First, 47 high school students were interviewed to identify life stressors. Second, 208 students were surveyed via internet questionnaires to assess stress level for each stressor. Lastly, in order to survey stress coping skills, 61 students answered 10 subjective questions orally or in writing. RESULTS: Thirty-seven life stressors in five categories were identified through thematic content analysis of the interviews: dormitory life, appearance and self management, human relations, study, and other areas. Stresses from schoolwork were highest and participants also experienced stress from their dormitory life. The overall stress level was higher in girls than in boys, and students in their 2nd year perceived their stress as higher than those in other grades. Various stress coping skills were being used, and positive coping skills were commonly used. CONCLUSION: To improve quality of life of boarding high school students, various strategies are needed to reduce their life stress. Especially, girls are in need of special concern and care because of their vulnerability to stress.

PURPOSE: The purpose of this study was to examine effects of nitric oxide synthase (NOS) inhibitor on muscle weight and myofibrillar protein content of affected and unaffected hindlimb muscles in rats with neuropathic pain induced by unilateral peripheral nerve injury. METHODS: Neuropathic pain was induced by ligation and cutting of the left L5 spinal nerve. Adult male Sprague-Dawley rats were randomly assigned to one of two groups: The NOSI group (n=19) had NOS inhibitor (L-NAME) injections daily for 14 days, and the Vehicle group (n=20) had vehicle injections daily for 14 days. Withdrawal threshold, body weight, food intake and activity were measured every day. At 15 days all rats were anesthetized and soleus, plantaris and gastrocnemius muscles were dissected from hindlimbs. Muscle weight and myofibrillar protein content of the dissected muscles were determined. RESULTS: The NOSI group showed significant increases as compared to the Vehicle group for body weight at 15 days, muscle weight and myofibrillar protein content of the unaffected soleus and gastrocnemius. The NOSI group demonstrated a higher pain threshold than the vehicle group. CONCLUSION: NOSI for 14 days attenuates unaffected soleus and gastrocnemius muscle atrophy in neuropathic pain model.

PURPOSE: The purpose of this study was to determine the effect of Dehydroepiandrosterone (DHEA) administration alone or exercise combined with DHEA before steroid treatment on rat hindlimb muscles. METHODS: Male Sprague-Dawley rats were assigned to one of three groups: a steroid group (S, n=10) that had no treatment for 7 days before steroid treatment; a DHEA-steroid group (DS, n=8) that had 0.34 mmol/kg/day DHEA injection once a day for 7 days before steroid treatment and an exercise?steroid group (EDS, n=9) that ran on the treadmill combined with 0.34 mmol/kg/day DHEA injection for 7 days before steroid treatment. At 15 days all rats were anesthetized and soleus, plantaris and gastrocnemius muscles were dissected. Body weight, food intake, muscle weight, myofibillar protein content and cross-sectional area of the dissected muscles were determined. RESULTS: The DS group showed significant increases (p<.05) as compared to the steroid group in body weight, and muscle weight of gastrocnemius muscles. The EDS group showed significant increases (p<.05) as compared to the S group in body weight, muscle weight, myofibrillar protein content, and Type II fiber cross-sectional area of soleus, plantaris and gastrocnemius muscles. CONCLUSION: Exercise combined with DHEA administration before steroid treatment prevents steroid induced muscle atrophy, with exercise combined with DHEA administration being more effective than DHEA administration alone in preventing muscle atrophy.

PURPOSE: The purpose of this study was to examine the effects of exercise on muscle weight and Type I and II fiber cross-sectional area of affected and unaffected hindlimb muscles in rats with neuropathic pain induced by unilateral peripheral nerve injury. METHODS: Neuropathic pain was induced by ligation and cutting of the left L5 spinal nerve. Adult male Sprague-Dawley rats were randomly assigned to one of two groups: The Pain+Exercise (PE) group (n=21) and the Sham+Exercise (SE) group (n=20). All rats had 28 sessions of treadmill exercise at grade 10 for 30 minutes, twice/day at 10 m/min for 14 days. Body weight, food intake and activity were measured every day. At 15 days all rats were anesthetized and soleus, plantaris and gastrocnemius muscles were dissected. Muscle weight and Type I, II fiber cross-sectional area of the dissected muscles were measured. RESULTS: The PE group showed significant increases (p<.05), as compared to the SE group for body weight and total diet intake, muscle weight of the unaffected soleus and plantaris, and in Type I and II fiber cross-sectional area of unaffected three muscles and affected plantaris. CONCLUSION: Exercise for 14 days attenuates unaffected soleus, plantaris and gastrocnemius muscle atrophy in neuropathic pain model.

PURPOSE: The purpose of the study is to find whether there is any effect on shortening the length of stay of long term patients due to issuing of hospitalization sheets by emergency department. METHODS: For the investigation, 27,948 patients who resided in hospitals over 6 hours from 2006 to 2007 were chosen as the subjects. The main materials for the investigation were various time variables according to the medical records. For the verification of each factor, Student's t-test and Pearson' correlation coefficient were used. RESULTS: There was statistically significant difference in regard to length of stay (p<0.01). The departments related to internal medicine showed that they required longer times in every aspect compared to those of non-internal medicine. There were statistically significant differences (p<0.01) in regard to the time of patients' length of stay and the time of issuing sheets for hospitalization according to the numbers of related department. However, there was no meaningful difference in regard to the waiting time for hospitalization. CONCLUSION: In conclusion, in the cases of long term patients who stayed over 6 hours in 2007 when the random sheets for hospitalization were issued by emergency department, the length of stay was significantly reduced. It was found that the time was more increased in the departments of internal medicine than the departments of noninternal medicine and when the related sub departments increased.

PURPOSE: This study was conducted to determine whether low intensity regular exercise following dexamethasone treatment could attenuate steroid-induced muscle atrophy. METHOD: 36 Wistar-rats(90-110g) were divided into six groups: control group(C), dexamethasone treatment group(D), sedentary group after normal sedentary period(C+S), sedentary group after dexamethasone treatment period(D+S), exercise group after normal sedentary period(C+E), and excercise group after dexamethasone treatment period(D+E). D, D+S, and D+E groups received dexamethasone injection(5mg/Kg) for seven days whereas C, C+S, and C+E groups received normal saline injection. Both C+E and D+E groups ran on a treadmill for 60 minutes/day(20minutes/4hours) at 15m/min and a 10degreegrade for seven recovery days. RESULT: Post-weight(body weight before muscle dissection) of D group significantly decreased by 16.03%, and that of D+E group significantly increased by 15.51% compared with pre-weight(body weight before steroid treatment). Type II muscle(plantaris and gastrocnemius) weights of D group were significantly lower than those of C group. Myofibrillar protein contents of type II muscles of D group tended to decrease comparing with C group. In D+E groups, body weights and relative weights of typeII muscles(muscle weight(mg)/post-weight(g)) tended to increase comparing with D+S group. CONCLUSION: It is suggested that steroid- induced muscle atrophy can be ameliorated through low intensity regular exercise after dexamethasone treatment.

PURPOSE: This study was to determine the effect of DHEA administration before, during, and after dexamethasone treatment on body weight and TypeI,II muscle weight of rat receiving dexamethasone treatment. METHOD: Wistar rats were divided into 6 groups: control(C), dexamethasone(D), DHEA administration for 3days after dexamethasone treatment for 7days(7D+3DH), dexamethasone treatment for 7days after DHEA administration for 3days(3DH+7D), DHEA administration during dexamethasone treatment for 4days after dexamethasone treatment for 3days(3D+4DDH), DHEA administration during dexamethasone treatment for 7days(7DDH). Dexamethasone was injected by subcutaneously daily at a dose of 5mg/kg. DHEA was orally administered daily at a dose of 5mg/kg for 7 days. Soleus(TypeI) muscle, and both plantaris and gastro- cnemius(TypeII) muscles were dissected on the 7th day of experiment. RESULT: Body weight of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. Body weight of 7D+3DH group decreased significantly compared with that of 7D group, 7DDH group, 3DH+7D group and 3D+4DDH group. Muscle weight of both plantaris and gastro- cnemius tended to decrease compared with that of 7D group. Muscle weight of 7DDH group, 3D+4DDH group and 3DH+7D group increased significantly compared with that of 7D+3DH group. Muscle weight of gastrocnemius of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. CONCLUSION: Based on these results, it can be suggested that DHEA administration before and during dexamethasone treatment can increase both body weight and mass of atrophied TypeII muscle induced by dexa- methasone treatment.

PURPOSE: The purpose of this study was to determine the effect of dehydroepiandrosterone (DHEA) on recovery of muscle atrophy induced by Parkinson's disease. METHODS: The rat model was established by direct injection of 6-hydroxydopamine (6-OHDA, 20 microg) into the left striatum using stereotaxic surgery. Rats were divided into two groups; the Parkinson's disease group with vehicle treatment (Vehicle; n=12) or DHEA treatment group (DHEA; n=22). DHEA or vehicle was administrated intraperitoneally daily at a dose of 0.34 mmol/kg for 21 days. At 22-days after DHEA treatment, soleus, plantaris, and striatum were dissected. RESULTS: The DHEA group showed significant increase (p<.01) in the number of tyrosine hydroxylase (TH) positive neurons in the lesioned side substantia nigra compared to the vehicle group. Weights and Type I fiber cross-sectional areas of the contralateral soleus of the DHEA group were significantly greater than those of the vehicle group (p=.02, p=.00). Moreover, extracellular signal-regulated kinase (ERK) phosphorylation significantly decreased in the lesioned striatum, but was recovered with DHEA and also in the contralateral soleus muscle, Akt and ERK phosphorylation recovered significantly and the expression level of myosin heavy chain also recovered by DHEA treatment. CONCLUSION: Our results suggest that DHEA treatment recovers Parkinson's disease induced contralateral soleus muscle atrophy through Akt and ERK phosphorylation.
