Hematopoietic actions induced by administration of Astragali radix, Angelicae gigantis radix, Rehmanniae radix preparat and Cervi pantotrichum cornu were compared in SAM R1 and P6. We measured complete blood cells such as RBC, Hb and Hct using Coulter's method and compared the results each other in a view of traditional Korean medicine. The administration of Angelicae gigantis radix did not induce hernatopoietic actions in SAMs and also was quite different those from the other 3 herbs. Thus, the mechanisms of the hematopoietic action by Astragali radix, Angelicae gigantis radix, Rehmanniae radix preparat and Cervi pantotrichum cornu could be different each other.

Cardiac tumors, especially the primary tumors involving any part of the heart are extremely rare and its relative incidence has been reported to be approximately 0.02%. We report a patient with huge cardiac hemangioma who complained of shortness of breath, general weakness, and dizziness, Imaging study by echocardiography and computed tomography of thorax revealed a huge lobulating mass like a bunch of grapes in the right chamber of heart. The surgical exploration of thorax was performed and a histological diagnosis of spindle cell hemangioma was obtained by microscopy. The patient was treated by surgical resection of the tumor and doing well after surgery. Our experience indicated that prompt diagnosis and treatment of cardiac hemangioma is imperative for patients' prognosis.
적층압축에 의한 접합재의 경계면 성장거동에 대한 수치 시뮬레이션
정태훈,류제구,後藤學 서울産業大學校 1997 논문집 Vol.45 No.1
Under plane strain compression, of two blocks with sawtoothed interface, the sawtooth growth occurred. We presumed in the previous paper that such growth was caused by the shear-band formation starting from the tip of sawtooth and its degree depended on the material properties of the block. In this paper, Compression in the case where similar blocks are twinned and also compression in the case where dissimilar blocks are twinned variously are carried out in the condition of lubricated interface. Further, in the latter, compression where the interface is degreased is also performed. The degree of growth is experimentally investigated. Moreover, numerical simulations are carried out by the elastic-plastic FEM for the case of the dissimilar blocks with the initial sawtooth angle of 60℃ . In the experiment, the harder material yields larger growth than the softer one, and the growth in the case of initial sawtooth angle 60℃ is greater than that of 90℃ . Larger ratio of total height to sawtooth height gives larger growth in comparison with the previous experimental result. In the case where the dissimilar blocks are twinned, larger difference between material properties leads smaller growth, and the degreased interface leads smaller growth than that in the lubricated one. Furthermore, by the simulation of compression where dissimilar blocks are twinned, it is confirmed that the tendency of the general deformation pattern is very similar to the experiment.

Seasonal and vertical distributions of dissolved and particulate organic carbon were investigated from May 1995 to March 1997 in n deep mesotrophic reservoir, Lake Soyang, POC contentrations at the dam site ranged from 0.1 to 1.8 mgC/L and DOC concentrations ranged from 1.4 to 4.9 mgC/L. POC concentrations in the surface layer were higher in the season of cyanobacterial bloom, July to September. High POC was observed at the depth of 30 to 60m after storm runoff in summer monsoon season. Turbid storm runoff formed intermediate current laden with much particulate materials from terrestrial sources. The vertical and seasonal variation of DOC was smaller than POC. Higher DOC was observed near the lake bottom which implies sedimentation and degradation of much organic detritus at the bottom. The ratio of DOC : POC varied from 2 to 60, and the ratio was lowest in September 1995 when algal density was highest. DOC : POC ratio of the main inflowing river, the Soyang River, varied from 1 to 10, and the ratio was low in storm runoff when the POC concentration was high.

감염성 심내막염은 화상 후에 발생할 수 있는 치명적인 합병증이다. 임상 증상은 일반적으로 없는 경우가 대부분이고 지속되는 발열과 양성 혈액 배양 검사가 유일하다. 감염의 다른 확실한 원인 없이 발열과 양성 혈액 배양 검사가 있을 때는 감염성 심내막염을 강력하게 의심해야 하며 심장 초음파로 진단 가능하다. 감염성 심내막염은 사망률은 높지만 초기에 진단하면 항생제 정주를 지속하는 것으로 치료할 수 있다. 저자들은 화상환자에서 발생한 수술적 처치를 필요로 하는 감염성 심내막염 2예를 경험하였기에 보고하는 바이다. Infective endocarditis is a rare but fatal complication following burn injury. The clinical presentation is silent, but with persistent fever and positive blood culture. The manipulation of clinical care as well as the burn wound itself and immunosuppression caused by extensive bums puts the burn patients at risk of bacteremia. Staphylococcus aureus and Gram-negative bacilli are most common pathogens of infective endocarditis following burns. We report herein two cases of infective endocarditis in the burn patients who requires surgical intervention. The first case was caused by Pseudomonas aeruginosa with complication of multifocal pneumonia, and the second case by coagulase-negative stapylococcus with cerebral hemorrhage.

본 연구는 농촌지역 성인의 주요 식품 섭취 빈도와 혈압, 비만도, 허리/둔부 둘레비, 콜레스테롤과의 관계를 분석하고자 G군 소재 890명(남성438명, 여성 452명)명을 조사대상으로 식품섭취 빈도 및 생리적 지수에 대한 조사를 하였으며 그 결과는 다음과 같다. 본 연구대상자는 남자가 49.2%, 여자가 50.8% 이었고, 연령별로는 60세 이상이 39.7%이었다. 학력으로는 고졸 이상이 43.8%이었고, 결혼한 경우가 84.3%이었으며, 직업은 농업인 경우가 46.7%이었다. 자신의 건강상태를 좋다고 인지한 경우는 31.9%이었고, 나쁘다고 인지한 경우는 21.9%이었다. 흡연자는 20.7%이었으며, 혈압상태는 고혈압전단계가 14.9%이었고, 고혈압인 경우가 12.1%이었다. BMI는 25.0kg/m2이상인 비만인 경우가27.1%이었다. WHR은 남자인 경우는 0.90이상, 여자인 경우는 0.85이상으로 비만인 경우가 42.0%이었다. 콜레스테롤은 200mg/dl이하로 정상인 경우가 76.1%이었고, 201mg/dl를 넘는 경우가 23.9%이었다. 뇨당은 양성인 경우가 8.7%이었다. 연령을 보정하여 식품섭취 빈도와 생리적 지수와의 관계를 보면 혈압은 과일류(p=.003)를 자주 섭취한 군이 혈압이 정상이었으며, BMI는 우유류(p=.045)를 자주 섭취한 군과 주류(p=.007)를적게 섭취한 군이 BMI가 정상이었다. 허리/둔부 둘레비는 채소류(p=.046)와 우유류(p=.021)를 자주 섭취한 군과 주류(p=.003)를 적게 섭취한 군이 정상이었고, 콜레스테롤은 곡류(p=.020), 두류(p=.039) 및 해조류(p=.007)를 자주 섭취한 군이 콜레스테롤 수치가 낮은 결과를 보였다. 이상의 연구결과를 종합하면 혈압은 과일류, BMI는 우유류와 주류, 허리/둔부 둘레비는 채소, 우유류 및 주류, 콜레스테롤은 곡류, 두류 및 해조류 섭취와 유의한 관련성을 보여 식생활 개선에 대한 인식을 높이고 개개인에게 맞춤식 건강 증진 사업을 전개해 나가는 것이 필요하다고 사료된다. Objectives: The objective of this study was to identify the association of food intake with bio-physiological indicators: blood pressure, body mass index (BMI), waist/hip ratio (WHR), cholesterol and urine sugar among rural people. Methods: The subjects were 890 inhabitants from 14 towns of G County in Honam province. Data were collected by interview and self-reported with structured questionnaires from April 6th to 30th 2005. Data were analyzed with the frequency, percentage, t-test, χ²-test, ANOVA, Scheffe test and ANCOVA using SPSS 12.0 program. Results: Pre-hypertensive and hypertensive group was 27.0%, overweight and obese 27.1%, more than 0.90 in WHR 42.0%, more than 201 mg/dl of cholesterol 23.9%, and positive urine sugar was 8.7% in general. Among eleven food groups, fruit intakes were more effective in normotensive group than in the others. Vegetables, liquors, and milk products were 0.90 WHR more effective than the others. Milk products and liquors in BMI, and grains, beans and seaweed in low cholesterol group were more effective than the others. Conclusions: Bio-physiological indicators are related significantly only with fruits, milk products, meats, cereal and liquors among eleven food categories. Further study on the relationship between food intake, physical activities, smoking, drinking and lifestyle with bio-physiological indicators are suggested.
