The pulmonary cavernous hemangioma is usually from birth and there may be without symptoms until adulthood. Larger or multiple pulmonary angiomata with considerable pulmonary arteriovenous shunts may cause cyanosis, finger clubbing, dyspnea and frequently accompanyingbruit. Recently, we experienced a case of cavernous hemangioma of the lung. A 34-year-old woman was admitted to our hospital for surgical evaluation of a 4 cm solitary, round nodule in the right upper lobe on the chest X-ray and CT scan. She had no symptoms. Laboratory findings are within normal limits except for elevated glucose levels. At surgery, the mass was well encapsulated and easily excised from the peripheral portion of the posterior segment of the right upper lobe. Grossly, it consisted of a 4 cm in diameter, round, soft, sponge-like, hemorrhagic, slightly lobulated mass with a smooth external surface. Microscopically, the mass was composed of vessels, which were thin walled, dilated and filled with blood. The wall of the abnormal vessels was thin and composed of endothelium and fibrous connective tissue with only a little smooth muscle. Immunohistochemically, the wall of the dilated abnormal vessesls showed negative reaction for cytokeratin(low and high) and epithelial membrane antigen but weakly positive reaction for UEA-1 in focal areas.

PURPOSE: The purpose of this study was to investigate the diametral tensile strength of polymer-based temporary crown and fixed partial denture (FPD) materials, and the change of the diametral tensile strength with time. MATERIAL AND METHODS: One monomethacrylate-based temporary crown and FPD material (Trim) and three dimethacrylate-based ones (Protemp 3 Garant, Temphase, Luxtemp) were investigated. 20 specimens (the empty set 4 mm x 6 mm) were fabricated and randomly divided into two groups (Group I: Immediately, Group II: 1 hour) according to the measurement time after completion of mixing. Universal Testing Machine was used to load the specimens at a cross-head speed of 0.5 mm/min. The data were analyzed using one-way ANOVA, the multiple comparison Scheffe test and independent sample t test (alpha = 0.05). RESULTS: Trim showed severe permanent deformation without an obvious fracture during loading at both times. There were statistically significant differences among the dimethacrylate-based materials. The dimethacrylate-based materials presented an increase in strength from 5 minutes to 1 hour and were as follows: Protemp 3 Garant (23.16 - 37.6 MPa), Temphase (22.27 - 28.08 MPa), Luxatemp (14.46 - 20.59 MPa). Protemp 3 Garant showed the highest value. CONCLUSION: The dimethacrylate-based temporary materials tested were stronger in diametral tensile strength than the monomethacrylate-based one. The diametral tensile strength of the materials investigated increased with time.

8.A study on the Frequency of Sister Chromatid Exchanges in Peripheral Lymphocytes among Painters.
Korean Journal of Occupational and Environmental Medicine 1994;6(2):332-341
The author studied the frequencies of sister chromatid exchanges of cultured peripheral Iymphocytes from 51 chromium exposed workers and 29 controls in order to examine the inductivity of sister chromatid exchanges of cultured peripheral lymphocytes of chromium exposed workers, from June 1989 to March 1990. The results obtained were as follows; 1. Mean frequencies of sister chromatid exchanges of cultured peripheral lymphocytes were 9.33+/-2.57 from chromium exposed workers and 7.59+/-0.81 from control, respectively, and the former was significantly higher than the latter (p<0.01) . 2. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by duration of employment from chromium exposed workers was increased in proportion to that, but there was no statistical significance. 3. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by chromium concentration in blood and urine of chromium exposed workers were not significantly increased. 4. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by levels of alcohol consumption in chromium exposed workers was inclined to increase in proportion to that. 5. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by number of cigarettes smoked was significantly increased in proportion to that in both chromium exposed workers and controls (p<0.05) . 6. In drinkers of chromium exposed workers, the frequencies of sister chromatid exchanges of cultured peripheral lymphocytes in smokers was higher than non-smokers, but there was no statistical significance.

PURPOSE: This study was conducted to understand the meaning of mind control as it is understood by elderly persons in Korea. METHOD: This study was conducted by engaging three elderly persons who are over the age of sixty five and presently residing in Seoul. Several in depth interviews were conducted with these individuals from March 2003 until November 2003. The contents of the interviews were analyzed using the Giorgi Method (1985), which places the emphasis on discovering meaning within the phenomenological context of an individual's experience. RESULTS: The analysis of the contents revealed the following four components with regard to the meaning of mind control for elderly persons (1) Settling the mind (2) Gradual lowering of expectations and hope for the success of offspring, (3) Having good thoughts and acting accordingly, and (4) Making up one's mind to follow the 'natural flow of life'. CONCLUSION: By allowing a wider and deeper understanding of the meaning of mind control for elderly persons the results of this study provide a basis for improving the care of elderly with a holistic perspective.
