Based on our experience with 23 frontotemporal reconstructions performed, this paper attempts to provide guidelines for appropriate selection among the four most commonly employed materials (e.g., autogenous parietal bone, silicone rubber, methylmethacrylate, and porous polyethylene) so that optimal results can be achieved. Clinical follow-up ranged from 6 to 91 months (mean 32 months). Every patient was analyzed clinically by ordinary scale method. The mean defect size was 134.8 cm2 in the silicone rubber, 36.5 cm2 in the methylmethacrylate, 17.4 cm2 in the autogenous bone graft and 7.3 cm2 in the porous polyethylene. The clinical assessment was excellent (mean, 29.3 points) in silicone rubber, excellent (mean, 28.6 points) in autogenous bone, excellent (mean, 26.8 points) in methylmethacrylate, and good (mean, 24.8 points) in polyethylene. To sum up, a large bony defect of congenital calvarial anomaly produced an excellent result using custom-made silicone implant. A relatively small bony defect with a scarred bed produced an excellent result using autogenous parietal bone grafting. Unexpected and medium-sized defect was reconstructed successfully through a simple procedure using methylmethacrylate. Porous Polyethylene was used at an incidental small defect because of its expensiveness.

Intracompartmental pressure of leg was measured by the slit catheter technique in one hundred fifty compartments of one hundred cases; fifty were from healthy young male adults, the others were from tibial fractured patients during three years from March 1983 to Fobruary 1986. The results were as follows; 1. Slit-catheter technique was found as a accurate method for continuous pressure monitoring. 2. The range of normal pressure was from zero to six millimeters of mercury(1.45mmHg±0.85). 3. Tissue pressure was 0–15mmHg(4.03mmHg±1.83) in unaffected side of fractured patients, 4–35mmHg(14.65mmHg±2.05) in affected side of fractured patients.

The prevalence of non-alcoholic fatty liver disease (NAFLD) is steadily increasing in conjunction with increases in obesity, type 2 diabetes, and physical inactivity. NAFLD encompasses a spectrum of conditions associated with lipid deposition in hepatocytes, ranging from simple steatosis to non-alcoholic steatohepatitis (NASH) and to advanced fibrosis and cirrhosis. A large proportion of patients with NAFLD have co-existing metabolic syndrome, which is also a major risk factor of cardiovascular disease. There is an urgency to recognize that NAFLD poses an additional risk for cardiovascular disease and should involve early aggressive risk factor modification. A lifestyle modification of diet and physical activity targeting substantial weight loss is considered as the first-line defense system against NAFLD. In this review, the roles of physical activity are discussed as an effective and safe means to combat NAFLD and its metabolic complications.

PURPOSE: To evaluate protective mechanism of melatonin against radiation damage and its relationship with apoptosis in mouse jejunum. MATERIALS AND METHODS:' 168 mice were divided into 28 groups according to radiation dose and melatonin treatment. To analysis crypt survival, microcolony survival assay was done according to Withers an (l Elkind's method. To analysis apoptosis, TUNEL assay was done according to Labet-Moleur's method. RESULTS: Radiation protection effect of melatonin was demonstrated by crypt survival assay and its effect was stronger in high radiation dose area. Apoptosis index with 8 Gy irradiation was 18.4% in control group and 16.5% in melatonin treated group. After 18 Gy, apoptosis index was 17.2% in control group and 15.4% in melatonin treated group. Apoptosis index did not show statistically significant difference between melatonin treated group and control group. CONCLUSION: Melatonin shows clear protective effect in mouse jejunum against radiation damage but it.', protective effect seems not to be related with apoptosis protection effect.

OBJECTIVES: To investigate the factors associated with symptoms from job stress among Korean dental laboratory technicians. METHODS: We collected the data of 786 technicians for life-style, job stressor, social support, self-esteem, personality, and various dimension of stress symptoms included roomatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, and hostility by self-administerd questionnaire. Global severity index of dental technician (GSID) was calculated by total sum of sub-dimension. RESULTS: We used 80 percentile as a cut-off point, and got the 81.5 % of sensitivity, 86.1 % of specificity by receiver operating characteristic curve. The odds ratios of various factors in high group of GSID compared with low group were 1,49(95 % Cl 1.00-2.00) for smoker, 1,53 (1.06-2.21) for unhealthy group, 6,69 (4.74-9.44) for work overload, 8.34(5.82-11.97) for work demand, 9.89 (6.76-74.94) for work process, 8.27 (5.80-11,79) for work environment, 5.82 (4.04-8.39) for interpersonal relationship, 8.34 (5.82-11.97) for occupational conflict, 5.70 (4.04-8.04) for labor remuneration, 7.58 (5.37-10.71) for role conflict, but 0.39 (0.27-0.57) for social support, 0.41 (0.29-0.60) for self-esteem. By multiple logistic regression, factors were significantly associated with GSID were age, working area, role overload, work demand, work procedure, physical environment, occupational conflict, role conflict, social support, personality traits. CONCLUSIONS: Factors associated with symptoms from stress were role overload, work demand, work procedure, occupational conflict, interpersonal relationship, labor remuneration and role conflict in Korean dental laboratory technicians. It is suggested that health promotion program to reduce job stress and to enforce social support and self-esteem should be developed.
