Object : This study was conducted as part of the national project to standardize stroke diagnosis in Korean medicine. In this study, we aimed to evaluate the characteristics of acute stroke between heat pattern group and cold pattern group. Methods : We recruited stroke patients from 5 universities(Kyung-Hee University oriental medical center, Kyung-Hee University East-West Neo medical center, Kyungwon university lncheon oriental medical center, Kyungwon university Songpa oriental medical center and DongGuk university llsan oriental medical center) from April, 2007 until February, 2010. We diagnosed them and selected 463 heat pattern patients and 182 cold pattern patients. Results : We find that the risk factor of smoking, alcohol, diet(prefer to meat) are more associated with the heat pattern group. On the other hand, inflammation history in recent 3 months and diet(prefer to sea food) are more associated with the cold pattern group. RBC, Hg, Hct, TG, CK and Cl are more related to the heat pattern group. CPT, total cholesterol and HDL are more related to the cold pattern group. Tae-eum type takes high distribution of the heat pattern group, and So-eum type takes high distribution of the cold pattern group. Conclusions : This study provides evidence that the heat pattern group have more risk factor than the cold pattern group.

Petroleum refineries have been considered as an important emission source for atmospheric volatile hazardous air pollutants(HAPs). The emission source includes petroleum refinery processes and process equipment. The control strategy for volatile HAPs requires emission estimations of these pollutants. However, systematic methods of volatile HAPs emission from petroleum refineries have not yet been established. Accordingly, present study surveyed the estimation method of volatile HAPs emitted from the petroleum refinery processes and process equipment. The emission estimation methods for the petroleum refinery processes are applied for 11 petroleum refining facilities: fluidized catalytic cracking, thermal cracking, moving bed catalytic cracking, compressed engine, blowdown system, vacuum distilled column condensator, natural gas or distilled boiler, natural gas or distilled heater, oil boiler, oil heater and flare. Four emission estimation methods applied for the petroleum refinery process equipment are as follows: average emission factor approach, screening ranges approach, EPA correlation approach and unit-specific correlation approach. The process equipment for which emission factors are available are valves, pump seals, connectors, flanges and open-ended lines.

조성옥,한헌석,차상훈,이경희,박범수,하태선,채수안 충북대학교 의과대학 충북대학교 의학연구소 1995 忠北醫大學術誌 Vol.5 No.2

신증후군에서는 동맥 및 정맥의 혈전에 의한 혈전색전증의 위험이 높다. 이는 혈 중 응고인자 Ⅰ, Ⅱ, Ⅶ, Ⅷ, Ⅹ등의 증가와 뇨소실로 인한 antithrombin Ⅲ의 감소, 섬유소 용해계의 변화, 혈소판 응집력의 증가에 기인하며 그 외 스테로이드 투여, 이뇨제 투여, 저체액 상태도 관여한다고 생각하나 이런 과응고현상에 대한 정확한 병태생리는 규명되고 있지 않다. 저자들은 내원 21개원 전 처음 신증후군 증상을 보였고 신장 조직 검사상 미세변화 신증후군으로 진단을 받고 스테로이드와 면역 억제제를 사용하였으나 6개월에 3-4회의 재발을 보이던 중 내원 1달 전 보호자 자의로 모든 약물 복용을 중단한 채로 지내다가 고열과 반혼수 상태를 보여 내원한 7세 남아에서 다발성 뇌경객증을 발견하였기에 문헌 고찰과 함께 보고하는 바이다. The risk of thromboembolism by arterial or venous thrombosis is high in the nephrotic syndrome. This may be due to the increased serum concentrations of the factor Ⅰ, Ⅱ, Ⅶ, Ⅷ, Ⅹ etc, decrease of antithrombin Ⅲ due to urinary loss, the change of thrombolytic system, increase in the platelet aggregation capacity, the use of steroid, diuretics, and hypovolemic state. But, the pathophysiology of this hypercoagulable state has not been clear. A 7-year- old boy had been diagnosed as having frequently relapsing minimal change nephrotic syndrome, 21 months ago. In spite of the administration of prednisolone and cytoxan, he had presented recurrent proteinuria in the frequency of 3-4 times per 6 months. From 1 month prior to visiting emergency room, his parents discontinued his medications, therefore, he showed fever and semicomatous mental status. In brain MRI study, multiple cerebral infarcts were noted. So, the authors report a case of multiple cerebral infarcts in a patient with frequently relapsing minimal change nephrotic syndrome with a brief review of related literature.

목 적 : 최근 칸디다혈증의 발생율이 매우 증가하여 병원 감염의 중요한 원인으로 대두되고 있다. 이에 저자등은 칸디다혈증에 대한 임상적 특성을 알아보기위하여 다음과 같이 연구하였다. 방 법 : 1988년 1월부터 1993년 12월까지 경희대학부속병원에서 발생하였던 병원성 칸디다혈증 61예를 대상으로 의무기록지를 검토하였다. 결 과 : 1) 연도별 발생 빈도는 1988년 부터 1933년까지 각각 2예, 7예, 9예, 11예, 15예, 17예로 증가하였으며, 최근에는 non-albicans 균주에 의한 감염이 증가하고 있었다. 2) 연령분포는 4-83세였으며 평균연령은 51.0±17.4세였고, 남자 32예, 여자 29예였다. 50대와 60대가 57.3%로 가장 많았다. 3) 균주별 발생빈도는 C. albicans 30예, C. tropicalis 13예, C. parapsilosis 10예, C. glabrata 6예, C. guilliermondii 1예, C. krusei 1예로서 C. albicans가 가장 많았다. 4) 기저질환으로 뇌혈관계질환이 25예(41%)로 가장 많았으며, 외과적질환 11예(18%), 고형악성종양 10예(16.4%), 혈액종양질환 9예(14.8%), 기타 내과적질환 6예(9.8%)였다. 5) 균주간 선행인자는 비슷하였으나, C. albicans와 C. tropicalis에서는 수술을 시행받은 예가 많았고, C. parapsilosis는 정주 영양 공급을 받은 경우가 많았다. 6) Amphotericin B 치료군(20예)과 fluconazole 치료군(11예) 사이에 예후에서 유의한 차이는 없었다. 7) 총 61예중 28예에서 사망하여 사망율은 45.9%였으며 정형외과적 수술을 시행받은 경우(83.3%)와 C. glabrata인 경우 사망율이 가장 높았다(83.3%). 결 론 : 칸디다 혈증은 중요한 병원 감염으로 대두되고 있으며 최근에는 non-albicans 진균주에 의한 병원성 칸디다 혈증의 발생율이 증가하는 추세이다. Background : The aim of this study is to determine the annual occurrence of nosocomial candidemia, the relation between Candida species and underlying illness, the relation bewteen Candida species and predisposing factors, and also to compare between the outcome of candidemia of the amphotericin B treatment group and that of the fluconazole treatment group. Methods : We reviewed medical records of 61 cases with nosocomial candidemia between 1988 and 1993 in Kyung Hee University Hospital retrospectively. Results : Two cases occurred in 1988, 7 in 1989, 9 in 1990, 11 in 1991, 15 in 1992, and 17 in 1993. The incidence of candidemia by non-albicans species has increased during this period and accounted for 64.7% in 1993. The infecting candida species were C. albicans(30 cases, 49.2%), C. tropicalis(13 cases, 21.3%), C. parapsilosis(10 cases, 16.4%), C. glabrata(6 cases, 9.8%), C. guilliermondii(1 case, 1.8%), and C. krusei(1 case, 1.8%). The most common underlying disease was cerebrovascular disease(41%) followed by surgical disease(18%), solid cancer(16.4%), hematological malignancies(14.8%), and other medical illness. There were no significant differences between the amphotericin B treatment group(n=20) and the fluconazole treatment group(n=11) in mortality. Overall mortality was 45.9%. The highest mortality was in patients with previous orthopaedic surgery(83.3%) and with C. glabrata candidemia(83.3%). Conclusion : Candidemia emerged as an important hospital infection and candidemia caused by non-albicans species has significantly increased in recent years.

고경식,권선희,안우석,이원욱,김구엽,서환조 대한감염학회 1995 감염 Vol.27 No.4

목적:B군 연쇄구균은 최근 보고에 의하면 만성 기저질환(당뇨병, 악성종양등)이 있는 성인에서 감염빈도 및 사망률, 이환율이 증가하고 있는 추세이며 그 중요성이 대두되고 있다. 이에 저자들은 B군 연쇄구균 감염의 임상양상, 기저질환(위험인자)을 알아보고, B군 연쇄구균 항균제 감수성등을 규명하고자 하였다. 방법:1986년 1월부터 1993년 12월까지 경희대학교 부속병원에서 B군 연쇄구균이 배양된 274예를 대상으로 의무기록지를 검토하였다. 결과: 1) 전체 연구대상은 274예로 98예(35.8%)가 남자였고, 176예(64.2%)가 여자였다. 이들의 연령분포를 보면 신생아군에서 감염이 많이 발생하였다 이후 감소추세를 보이다가 20대 이상에서 다시 증가 하는 추세를 보였다. 2) 감염 양상은 274명중 명확한 감염이 156명(56.9%), 추정감염이 55명(20.1%), 비감염이 63명(23.0%)이었다. 임신을 제외한 18세 이상의 성인은 231명으로 남자가 83명, 여자가 148명이었고 남여 비율은 1:1.78이었다. 이중 133예(57.6%)에서 명확한 감염이었고, 46명(19.9%)에서 추정 감염, 52명(22.5%)에서 비감염이었다. 명확한 감염환자 133명중 31명(23.3%)이 병원내 감염이였다. 3) 18세 이상의 성인 231명에서 Group B Streptococcus가 분리 동정된 감염 부위는 자궁 경부 77예(33.3%), 요 73예(31.6%), 객담및 상기도 39예(16.9%), 농 24예(10.4%)등이었다. 4) 명확한 감염을 가지고 있었던 성인 133명의 임상양상은 요로 감염 37명(28%), 자궁 경부염 37명(28%), 피부, 연조직 감염 23명(17%), 폐렴 10명(8%), 패혈증 8명(6%)등이었다. 5) 명확한 감염을 가지고 있었던 성인 133명중 92명(69%)에서 한가지 이상의 만성 기저질환이 있었으며, 이중 당뇨병 32%, 뇌 혈관 질환 21%, 고혈압 19%, 신부전 12%, 악성종양 5%등을 차지하였다. 6) 항균제 감수성 검사(251예)에서 penicillin 98.4%, cephalothin 99.6%, cefamandol 98.8%, erythromycin 96.0%, clindamycin 89.4%, oxacillin 88.8%, lincomycin 87.8%, methicillin 86.8%, minocycline 49.4%, trimethoprim-sulfamethoxazole 15.5%의 감수성을 보였다. 7) 명확한 성인 감염 133명중 6명(4.5%)이 사망하였다. 결론:B군 연쇄구균은 만성 기저질환이 있는 성인에서 감염 빈도가 높고, 치명적인 결과를 초래할수 있으므로 감염 예방 및 조기 발견, 적절한 항균제 감수성 검사에 따라 조기 치료로 사망률을 줄여야 할것으로 생각된다. Background: Several reports have suggested that the incidence of diseases caused by Group B streptococcus is increasing in nonpregnant adults, particularly those with serious underlying diseases. The objectives of this study were to define the clinical manifestations, underlying conditions(risk factors) of definite group B streptococcal diseases in nonpregnant adults and to obtain antimicrobial sensitivity of these infections. Methods: We analyzed the records of 274 cases of the Group B streptococcus isolated in Kyung-Hee University hospital between 1986 and 1993. Results: 1) Total Group B streptococcal isolates were 274 cases : Of these cases, 7 percent were 1 month of age or younger, 3 percent were older than 1 month but younger than 18 years of age, and 91 percent were 18 or older. 2) Men and nonpregnant women accounted for 87 percent (n=231) : 133 cases (57.6%) with definite infection, 46 cases(19.9%) with possible infection, and 52 cases(22.5%) with no infection. 31 cases of 133 (23.3%) nonpregnant adult with definite infection apeared to have acquired the disease nosocomially. 3) In the 133 nonpregnant adult patients, the most common clinical diagnosis were urinary tract infection(28%), and cervicitis(28%). 4) In the 133 nonpregnant adult patients, the underlying diseases or conditions were diabetes mellitus(32%), cerebrovascular accident(21%), hypertension(19%), renal failure(12%), and malignant neoplasm(5%), Sixty-nine percent of the cases had one or more underlying diseases. 5) In the antimicrobial sensitivity tests, 98.4% of isolates were sensitive to penicillin, 99.6% to cephalothin, 98,8% to cefamandol, 96.0% to erythromycin, 89.4% to clindamycin, and 49.4% to minocycline. 6) The case mortality rate was 4.5%(6 of 133). Conclusion:We found group B streptococcal infection to be a significant and apparently increasing cause of definite diseases in nonprognant adults, particularly in those with serious underlying diseases. Recognizing these infections early in the groups with serious underlying diseases will be helpful in lowering mortality.

PDGF와 IGF-I 병용 사용시 치주인대세표의 증식과 세포활성에 미치는 영향에 관한 연구

서조영,신홍인,경희문 경북대학교 병원 1997 경북대학교병원의학연구소논문집 Vol.1 No.1

Current acceptable methods for promoting periodontal regeneration are based on removal of diseased soft tissue, root treatment, guided tissue regeneration, introduction of new graft materials and biological mediators. Insulin-like growth factor-I(IGF-I) and Platelet-derived growth factor-BB(PDGF-BB), the members of the polypeptuyde growth factor family have been reported as the biological mediators which regulate a variety cellular matrix biologic activities of wound healing process including the cell proliferation, migration and extracellular matrix synthesis. The purposes of this study is to evaluate the combination effects of IGF-I and PDGF-BB on the cellular activity of the periodontal ligament cells to act as a regeneration promoting agent of periodontal tissue. Human periodontal ligament cells were prepared from the first permolar tooth extracted for the orthodontic treatment and were cultured in DMEM containing 10% FBS at the 37。C, 5% CO2 incubator. Author measured the DNA synthetic activity, and total protein, collagen and noncollagenous protein synthetic activities according to the concentration of 10, 100ng/ml IGF-I and 1, 10 ng/ml PDGF-BB in combination. The results were as follows: significantly increased in the 1 ng/ml PDGF-BB alone compared to the 10 ng/ml PDGF-BB alone(P<0.01)and in the 1 ng/ml PDGF-BB AND 10, 100NG/ML IGF-I in combination compared to the 1ng/ml PDGF-BB alone (P<0.05,P<0.01). The synthetic activity of the noncollagenous protein is increased according to the concentration of IGF_I, but not statistically significant(P>0.05). The percent of collagen is significantly in the 1ng/ml PDGF-BB and 10ng/ml IGF-I in combination compared to the 1ng/ml PDGF-BB alone(P0.05) and in the 10ng/ml IGF-I in combination compared to the 10ng/ml PDGF-BB alone(P<0.05). The synthetic activity of the DNA is in conclusions, the percent study shows that PDGF-BB and IGF-I in combination have a potentiality to enhance the DNA synthesis and the total protein and collagen synthesis of the periodontal ligament cells, especially it is more significant in the low concentration PDGF-BB compared to the high one. Thus, the PDGF-BB and IGF-I in combination may have important roles in promotion of periodontal ligament healing, and consequently, may useful for clinical application in periodontal regenerative procedures.
