The adequate treatment of tibia fracture is one of the most difficult due to severe commiuntion, open wound, delayed union, angulation deformity and infection. We treated 38 fractures of the tibia by Interlocking intramedullary nail from Feb. 1983 to Mar. 1993. 35 cases of the tibia fracture were fresh, 13 cases of fracture were open. The other 3 cases were delayed union and nonunion. The Mean follow-up was 14.0 months. The results were as followings. 1. Of the 38 fractures, 37 fractures united and the mean union time was 18.7 weeks. 2. Interlocking intramedullary nail could be used to the majority of fractures of the proximal & distal tibia shaft. fractures. 3. The Im erlocking nail had rigid rotational stability and was appropriate for the treatment in severe unstable fractures, commninution and open-with bone loss. 4. Delayed union or nonunion was a good indication for intramedullary nailling. 5. The major-complication were valgus deformity of 2 cases, varus deformity of 1 case, 1 case deep infection. 6. Interlocking intramedullary nailing provided rigid fixation of . fracture and then made early joint motion exercise and ambulation.

Background: Job training influences the overall working environment and worker's well-being. The purpose of this study is to find the relationship between job training and subjective well-being in accordance with occupations and understand the influence of task characteristics—work creativity and task variety (WCTV)—on the effect of training. Methods: A cross-sectional study based on the Fifth Korean Working Conditions Survey was conducted on 50,205 workers in the Republic of Korea. The World Health Oorganization–5 well-being index was used to measure their subjective well-being. The relationship between job training and subjective well-being was divided in accordance with the level of WCTV. Results: Training paid for by employer showed a negative effect on subjective well-being when received for more than 3 days (OR 0.88, p<0.01) in the last 12 months. Training paid for by oneself showed a positive linkage with well-being when the level of training was 1–3 days (Odds ratio = 1.55, p<0.001). This result showed different aspects in accordance with the level of WCTV. For the high WCTV group, the aforementioned results were reaffirmed, but for the group with low WCTV, job training did not show a statistically significant result on well-being. On-the-job training was not related to subjective well-being regardless of the level of WCTV. Conclusion Job training had different effects on subjective well-being depending on the type and frequency of training, as well as the WCTV. It is imperative to comprehensively apply different types of job training in accordance with the characteristics of occupations to uplift workers' well-being.

To observe the cellular expression of extracellular matrix components during mouse skin regeneration, the wounded skin samples were processed by immunoelectronmicroscopic methods, using primary antibodies for fibronectin, collagen type IV and laminin. The tissues were observed under transmission electron-microscope. The results were summarized as follows. 1. The granulation tissues and x-cells were observed in the wound margin at 18 hr post injury. The number of fibroblasts was increased in the granulation tissues at 1 day post injury. 2. The expression of fibronectin was observed in x-cells at 18 hr post injury, and in fibroblasts at 1 day post injury. In x-cells, after 1 day post injury, the expression of fibronectin was decreased. 3. At 1 day post injury, the expression of collagen type IV was increased in fibroblasts whereas not in x-cells. 4. The expression of laminin was increased by 18 hr post injury, but decreased after 1 day post injury. On the basis of above findings, in mouse, the regenerations of wounded skin were faster than other animals. The first step, infiltration response, was processed till 18 hr or 1 day post injury. The second step, fibroblast proliferation phase, began at 1 day post injury. In the regenerations of wounded skin, x-cells migrated to the wound region and activated, earlier than fibroblast. Thereafter, x-cells which appeared to be transformed into fibroblasts, played an important role in the synthesis of fibronectin and collagen type IV, and the formation of granulation tissue, with migrated fibroblasts to the wound region.

PURPOSE: To determine the role of zinc in febrile convulsion and to evaluate whether febrile convulsion causes neuronal damage, serum and cerebrospinal fluid(CSF), zinc and CSF neuron-specific enolase(NSE) levels were measured in patients with febrile convulsion, epilepsy and aseptic meningitis. METHODS: Three groups were formed as follows: group I:53 children with febrile convulsion; group II:34 children with epilepsy; and group III, 40 children with aseptic meningitis. Serum and CSF zinc and CSF NSE levels were measured in each groups. RESULTS: The serum zinc levels of groups I, II and III had a mean of 74.71+/-18.26 microgram/dL, 104.35+/-31.43 microgram/dL and 87.03+/-24.47 microgram/dL, respectively, and the values of group I were significantly lower than those of the other two groups. The CSF zinc levels of groups I, II and III were found to have a mean 27.72+/-17.93 microgram/dL, 44.73+/-26.72 microgram/dL and 54.44+/-28.43 microgram/dL, respectively. In group I, the CSF zinc levels were significantly lower than those of other two groups. The CSF NSE levels of groups I, II and III had a mean of 11.61+/-2.96 ng/mL, 16.51+/-5.46 ng/mL and 14.60+/-3.02 ng/mL respectively and the values of group I were significantly lower than those of others. CONCLUSION: We confirmed that low zinc levels in serum and CSF are participants in the pathogenesis of febrile convulsion, but we could not find out the evidence of neurologic damage in patients with febrile convulsion using NSE levels in CSF.

BACKGROUND: The hypertriglyceridemic waist (HTGW) phenotype is a simple and inexpensive screening parameter to identify people at increased risk of cardiovascular disease. We evaluated whether the HTGW phenotype predicts diabetes in urban Korean adults. METHODS: A total of 2,900 nondiabetic subjects (mean age 44.3 years), comprising 2,078 males (71.7%) and 822 females (28.3%) who underwent annual medical check-ups at our center between January 2005 and December 2009, were recruited. The subjects were divided into four groups according to baseline serum triglyceride (TG) level and waist circumference (WC): normal WC-normal TG (NWNT) level, normal WC-high TG level, enlarged WC-normal TG level, and enlarged WC-high TG (EWHT) level. High serum TG level was defined as > or =150 mg/dL and enlarged WC was defined as > or =90 cm for men and > or =85 cm for women. New cases of diabetes were determined according to questionnaires filled in by participants and the diagnostic criteria of the American Diabetes Association. Cox proportional hazards model analysis was used to assess the association of HTGW phenotype with the incidence of diabetes. RESULTS: A total of 101 (3.5%) new diabetes cases were diagnosed during the study period. The EWHT group had a higher incidence of diabetes (8.3%) compared with the NWNT group (2.2%). The adjusted hazard ratio for diabetes for subjects with the EWHT phenotype at baseline was 4.113 (95% confidence interval [CI], 2.397 to 7.059) after adjustment for age, and 2.429 (95% CI, 1.370 to 4.307) after adjustment for age, sex, total cholesterol, systolic blood pressure, and alcohol drinking history. It was attenuated by inclusion of baseline fasting glucose level in the model. CONCLUSION: Subjects with the HTGW phenotype showed the highest risk of incident diabetes. This tool could be useful for identifying individuals at high risk of diabetes.

BACKGROUND: Chronic kidney disease (CKD) is considered one of the most common risk factors for cardiovascular disease. Coronary artery calcification (CAC) is a potential mechanism that explains the association between renal function and cardiovascular mortality. We aimed to evaluate the association between renal function and CAC in apparently healthy Korean subjects. METHODS: A total of 23,617 participants in a health-screening program at Kangbuk Samsung Hospital were included in the study. Estimated glomerular filtration rate (eGFR) was assessed using the Cockcroft-Gault equation. Coronary artery calcium score (CACS) was measured via multidetector computed tomography. Subjects were divided into three groups according to the CKD Staging system with eGFR grade: stage 1, eGFR > or =90 mL/min/1.73 m2; stage 2, eGFR 60 to 89 mL/min/1.73 m2; and stage 3, eGFR 30 to 59 mL/min/1.73 m2. RESULTS: The mean age of the participants was 41.4 years and the mean eGFR was 103.6+/-21.7 mL/min/1.73 m2. Hypertension and diabetes were noted in 43.7% and 5.5% of the participants, respectively. eGFR showed a weakly negative but significant association with CACS in bivariate correlation analysis (r=-0.076, P<0.01). Mean CACS significantly increased from CKD stage 1 to 3. The proportion of subjects who had CAC significantly increased from CKD stage 1 to 3. Although the odds ratio for CAC significantly increased from stage 1 to 3 after adjustment for confounding factors, this significance was reversed when age was included in the model. CONCLUSION: In early CKD, renal function negatively correlated with the degree of CAC in Korean subjects. Age was the strongest effector for this association.

BACKGROUND: Metabolic health is an emerging concept that is highly correlated with various metabolic complications, and adipocytokines have been causally linked to a wide range of metabolic diseases. Thus, this study compared serum adipocytokine levels according to metabolic health and obesity status. METHODS: Four hundred and fifty-six nondiabetic subjects (mean age, 40.5 years) were categorized into four groups according to metabolic health and obesity status: metabolically healthy nonobese (MHNO), metabolically healthy obese (MHO), metabolically unhealthy nonobese (MUHNO), and metabolically unhealthy obese (MUHO). Being metabolically healthy was defined as the presence of fewer than two of the following five metabolic abnormalities: high blood pressure, high fasting blood glucose, high triglyceride, low high density lipoprotein cholesterol, and being in the highest decile of the homeostatic model assessment of insulin resistance index. Obesity status was assessed using body mass index (BMI), with obesity defined as a BMI higher than 25 kg/m2. Levels of serum interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor alpha (TNF-alpha), and adipocyte fatty acid binding protein (A-FABP) were also evaluated. RESULTS: Of the 456 subjects, 247 (54.2%) were in the MHNO group, 66 (14.5%) were in the MHO group, 66 (14.5%) were in the MUHNO group, and 77 (16.9%) were in the MUHO group. There were no significant differences in IL-6 or MCP-1 levels among the groups, but levels of TNF-alpha and A-FABP were significantly higher in the MUHNO group compared to the MHNO group. CONCLUSION: High TNF-alpha and A-FABP levels are significantly associated with metabolically unhealthiness in nonobese Korean individuals.
