To identify the drug abuse status and its determinant factors in high school boys in Taegu, the study was performed from April to May, 1995. Study population were selected by cluster sampling method and total 5,665 students replied to the self-administered questionnaire survey(2,207 in academic high school, 3,458 in business high school). The major findings were as follows; The proportion of drinking, smoking experience was 55.0%, 45.8%, respectively, and the proportion of current drinker, current smoker was 27.2%, 27.5%. The drinking, smoking experience rate of second grade students was higher than first grade and it was higher in business high school boys. The proportion of a stimulant, a hallucinogen, hemp leaf cigarets experience was 3.2%, 1.6%, 0.1%, respectively. Drug abuse had significant association with home environment(lower economic status, frequent move, death of father or mother, apart from family), parents environment(parents' indifference, parents' drinking and smoking, etc.), school life(lower school grades, intimate friend's drug abuse, etc.), generous attitude to drug abuse, higher level of stress. Students who replied that the law prohibited immature person(students) from drinking and smoking showed lower drug abuse rate. In multiple logistic regression analysis, second grade students, business high school students, parents' indifference, lower school grades, intimate friend's drug abuse, no recognition of the fact that the law prohibits high school students from drinking and smoking, generous attitude to drug abuse, higher level of stress were significantly related with alcohol abuse and smoking. Other drugs abuse were related with above factors. On consideration of above findings, to prevent students from drug abuse, we have to try together in house, school, and society.

PURPOSE: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. MATERIALS AND METHODS: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. RESULTS: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. CONCLUSION: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

This study was undertaken to observe the histologic changes of surrounding maxillary sutures to the widening of midpalatal suture, using two adult dogs, weighing about 10 kg, for experimental, and one for control group. After widening of the midpalatal suture with expansion screw for ten days was performed, and followed by sacrifice of experimental animals. Tissues were excised from 5 surrounding maxillary suture portions such as, internasal, interfrontal, midsagittal, zygomatrco-temporal, and midpalatal sutures. After that, the specimens were fixed and d calcified in 10% formalin sol. and 5% nitric acid. Embedding in paraffin end, serial sections at a thickness of 5 micron was done, After Hema toxylin Eosin staining and light microscopic examination, Following results were obtained 1. in midpalatal suture area, which showed most prominent histologic change, High degree of fibronlastic and osteoblastic proliferation lining the bony trabeculae with osteoid tissue projection into the fibrous connective tissue were observed. 2. In interfrontal suture area, moderate degree of fibroblastic and osteoblastic proliferation was observed. 3. In internasal suture area, active osteoblastic and osteoclastic proliferation lining the bony trabeculae was observed, and separation of fibrous connective tissue was also observed. 4. In midsagittal and zygomatico-temporal suture areas, no histologic changes can be observed.

For evaluating the change of strength of extraocular muscle after strabismus surgery, ten rabbits had been performed resection of lateral rectus muscle in right eye and recession of lateral rectus muscle in left eye, and then performed EMG(electromyography). We performed EMG before surgery, at immediate post-op,after 1 day,1,2,3,4,6,8 weeks. In case of resection of lateral rectus muscle, EMG value increased at immediate post-op then stabilized after 6 weeks. In case of recession of lateral rectus muscle, EMG value decreased at immediate post-op, then stabo; ozed after 6 weeks. Therefore, EMG is the useful method in evaluating the change of strength of EOM. Especially, during 6 weeks after surgery is the important peeriod for follow-up.

PURPOSE: The study assessed the effect of exogenous surfactant on oxygen and ventilator requirements and long-term prognosis of neonates with respiratory deterioration due to pulmonary hemorrhage. METHODS: From March 2007 to March 2011, neonates with respiratory deterioration due to pulmonary hemorrhage in Saint Mary's Hospital were identified from the database. Among 20 patients with pulmonary hemorrhage, 10 patients received surfactant therapy and the other 10 did not. We compared outcomes of these two groups. The primary outcome was changes in respiratory status following surfactant therapy, as reflected by oxygen index (OI), fractional inspired oxygen (FiO2) and mean airway pressure (MAP). Secondary outcomes were the duration of ventilation, nasal continuous positive airway pressure (NCPAP), oxygen inhalation days, progression to severe bronchopulmonary dysplasia or death, and retinopathy of prematurity, which required laser therapy. RESULTS: Surfactant treatment group had higher FiO2, MAP, and OI than the non-treatment group during pulmonary hemorrhage. But, there were no differences in FiO2, MAP, and OI after 2 hours of pulmonary hemorrhage between the two groups. There were no significant side effects during surfactant treatment in the surfactant treatment group. Surfactant treatment group had fewer ventilator days, NCPAP days (P<0.05) and a tendency towards shorter oxygen days than the non-treatment group (P=0.09). Also, the surfactant treatment group had less severe bronchopulmonary dysplasia (BPD) or death than the non-treatment group (10% vs. 70%, P<0.05). CONCLUSION: Exogenous surfactant appears to be a useful adjunctive therapy with neonates of severe respiratory deterioration due to pulmonary hemorrhage. Also, exogenous surfactant treatment dose not seen to be associated with any significant side effects during the therapy.

OBJECTIVE: To estimate association between laboratory findings such as serum lipid panel, urine pH, alkaline phosphatase, lactic acid and chronic low back pain patients. METHOD: A sample (n=112) of blue color employees in an engineering company were divided into three groups, degenerative herniated disc patients, degenerative spondylosis patients and radiculopathy patients. Each group was examined for the correlation between several factors and chronic low back pain. Several factors including laboratory findings with serum total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, urine PH, alkaline phosphatase, lactic acid and smoking were analysed. RESULTS: There was no association between the baseline total cholesterol, HDL-cholesterol, LDL-cholesterol, alkaline phosphatase, urine pH, lactic acid and chronic low back pain. However, the triglyceride levels were significantly higher in degenerative herniated disc patients, degenerative spondylosis patients and smokers. CONCLUSION: High serum triglyceride predicted incident degenerative chronic low back pain.
