An inviscid flow of the laminar flame in a channel is investigated by using the hydrodynamic model which considers a flame as a surface of discontinuity, separating burned from unburned gas and step-like changing density across that. It has been recognized that the plane flame of which basic flow is uniform is always unstable to an infinitesimal disturbance. In the present study, the basic flow of curved flames is determined at first for the stability study of 2-D flame. To solve the dummy boundary condition at the flame surface of burned region the flow field is analyzed by changing density ratio. The numerical result shows that the increasing of density ration causes to steep variation of streamline at flame front although the streamlines have a similar trend.

최정혜,안명주,오호석,이웅수,오석중,이영열,최일영,김인순 대한조혈모세포이식학회 2003 대한조혈모세포이식학회지 Vol.8 No.2

연구배경: 고용량 화학요법은 항암제의 투여 용량에 따라 항암효과가 비례하는 용량반응 관계가 있는 악성종양에서 효과를 기대할 수 있으며 현재 급성백혈병, 악성림프종, 다발성골수종 등의 혈액 종양과 유방암, 고환암, 난소암, 신경아세포종 등의 고형암 환자에서 시행되고 있다. 저자들은 고용량화학요법에 이어 자가조혈모세포이식을 시행 받은 악성 종양 환자를 대상으로 치료효과 및 부작용 등의 임상상을 알아보고자 하였다. 방법: 1997년부터 2003년까지 한양대학교 병원에서 자가조혈모세포이식을 시행 받은 악성 종양 환자 31예(남서 : 여성 15 : 16, 중앙연령: 50세, 다발성골수종 14예, 비호지킨림프종 9예, 유방암 4예, 호지킨림프종 3예, 급성골수성백혈병 1예)를 대상으로 후향적 분석을 시행하였다. 결과: 채집된 단핵구의 중앙값은 5.1×10^(8)/kg (범위 1.6~189.3)이었고 CD34양성세포수의 중앙값은 12.0×10^(6)/kg (범위 1.3~75.1)이었다. 말초혈액 과립구가 500/μL 에 도달하는 중앙값은 11일(범위 8~27)이었고 혈소판이 20,000/μL에 도달하는 중앙값은 11일(범위 0~32)이었다. 고용량 항암화학요법 후 21예가 완전관해, 5예가 부분관해에 도달하였다. 생존한 환자의 중앙추적기간은 29.5개월이었고 전체 환자의 2년 무병생존기간은 55.7%이었고 중앙값은 48.2개월이었다. 2년 생존기간은 62.9%이었으며 중앙값에는 도달하지 않았다. 10예의 사망환자 중 7예가 질병의 진행으로 사망하였고, 조기사망 3예(심부전과 신부전 1예, 장파열 1예, 패혈증 1예)가 있었다. 결론: 이 연구는 포함된 환자의 수가 적고 추적기간이 짧은 단점이 있으나, 다발성골수종, 악성림프종 등의 악성 질환에서 고용량 항암화학요법과 자가조혈모세포이식은 안전하고 효과적인 치료임을 추정할 수 있었다. Background: We performed the current study to evaluate the safety and efficacy of high-dose chemotherapy (HDC) with autologous peripheral blood stem cell transplantation (ASCT) in malignant diseases. Methods: Between January 1997 and March 2003, 31 patients (14 multiple myeloma, 9 Non-Hodgkin's lymphoma, 3 Hodgkin's disease, 4 breast cancer, and 1 acute myelogenous leukemia) underwent HDC with ASCT. Stem cells were collected by CS-3000 after mobilization treatment with chemotherapy and granulocyte colony-stimulating factor. The conditioning regimens included high-dose melphalan, BEAM (BCNU, etoposide, cytosine arabinoside, melphalan), BEAC (BCNU, etoposide, cytosine arabinoside, cyclophosphamide), CPB (cyclophosphamide, cisplatin, BCNU) and others. Results: There were 15 male and 16 female patients and median age was 50 years (range: 29~77). The median number of mononuclear and CD34+ cells was 5.1×10^(8)/kg (1.6~189.3) and 12.0×10^(6)/kg (1.3~75.1), respectively. The median time of neutrophil (>500/μL) and platelet (>20,000/μL) engraftment was 11 (8~27) and 11 (0~32) days after ASCT, respectively. Twenty-two patients experienced neutropenic fever. Twenty-one patients achieved complete remission and 5 patients achieved partial remission after HDC with ASCT. The median follow-up duration for surviving patients was 29.5 months. Causes of death included disease progression (7), sepsis (1), bowel perforation (1), and renal failure (1). Median progression free survival (PFS) was 48.2 months and median overall survival (OS) was not reached. Two-year PFS and OS was 55.7% and 62.9%, respectively. Conclusion: Our results suggest that HDC with ASCT was safe and effective modality in patients with various malignant diseases.

최정혜,안명주,조은경,신동복,이재훈,이문희,김철수 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.2

배경: 림프절 전이가 많은 고위험군 유방암환자에서 CPB(cyclophosphamide, cisplatin, BCNU)를 이용한 고용량화학요법 및 자가조혈모세포이식술이 무병생존율에 미치는 영향과 안전성을 규명하기 위하여 연구를 시행하였다. 방법: 1998년 2000년 까지 한양대학병원, 가천의대병원과 인하대학병원에서 4개 이상 림프절을 침범한 유방암으로 근치적 절제술 시행 후 고용량 화학요법과 자가조혈모세포이식을 시행 받은 13명의 환자를 대상으로 하였고 대조군은 4개 이상 림프절을 침범한 유방암으로 보조화학요법을 받은 환자들 중 39명을 무작위로 선택하여 비교분석하였다. 고용량 화학요법은 제-6일에 BCNU 450 mg/m², 제-5일부터 3일까지 cyclophosphamide 2.0 g/m²와 cisplatin 55 mg/m²를 각각 투여하였다. 결과: 채집된 단핵구수의 중앙값은 8.5 x 10^(8)/kg (범위 2.44-17.90)이었고 CD34양성세포수의 중앙값은 11.0 x 10^(6)/kg (범위 0.8-78.35)이었다. 모든 환자가 이식 후 중앙치 10.0일(범위 8-15)에 말초혈액 과립구가 500 /mm³에 도달하였고 중앙치 9.0일(범위 0-18)에 혈소판이 20,000 /mm³에 도달하였다. 고용량 화학요법을 시행 받은 환자군의 추적기간의 중앙값은 24.6 개월 (범위 15.5-40.5)이었으며 총 13명의 환자 중 1명이 뇌전이로 인하여 사망하였으며 3명(23.1%)에서 재발이 관찰되었다. 대조군은 재발율이 25.6%이었고 무병생존율은 고용량 화학요법을 시행 받은 군(70.5%)과 대조군(78.8%) 사이에서 통계학적으로 의미 있는 차이를 나타내지 않았다 (P=0.744). 고용량 화학요법을 시행 받은 환자 중 10명 76.9%에서 발열이 관찰되었고 WHO 기준 3도 및 4도의 부작용은 혈액학적 부작용이 6예, 소화기적 부작용이 6예에서 관찰되었다. 결론: 고위험군 유방암 환자에서 CPB를 이용한 고용량화학요법 및 자가조혈모세포이식술은 안전하게 적용할 수 있는 치료의 한 방법이나 고용량 화학요법의 효과에 대해서는 앞으로 발표될 대규모 3상 연구의 결과를 주시해야 할 것으로 생각된다. Background: Despite the improvement of prognosis by multimodality therapy for the treatment of breast cancer, primary breast cancer patients with multiple involved axillary lymph node still have a high risk of recurrence. Methods: Between January 1998 and May 2000, we treated 13 women with histologically proven stage II or III breast cancer with 4 or more axillary lymph nodes at the time of primary mastectomy with high-dose chemotherapy and autologous stem cell transplantation. Results: The median age was 45 years (range: 32-57) and the median number of involved lymph node was 13 (range: 6-31). Ten patients were premenopausal state and 40 percent were positive hormone receptor. Seven patients received radiation therapy. Patients were treated with high-dose CPB (cyclophosphamide 2 g/m² D-5--3, cisplatin 55 mg/m² D-5--3, BCNU 450 mg/m² D-6) with autologous peripheral blood stem cell transplantation after 2-4 cycles of adjuvant chemotherapy (CAF, CEF or AC). We compared those patients with age and other clinical factors-matched 39 patients who received conventional adjuvant chemotherapy. The median follow-up for surviving patients who received high-dose chemotherapy was 25.6 months. The relapse rate and 2-year relapse-free survival was 23.1%, 25.6% and 70.5%, 78.8% for high-dose and conventional dose chemotherapy, respectively, but there was no significant difference between two groups (P>0.05). Conclusion: Further follow-up and additional studies are required to resolve the role of high-dose chemotherapy with autologous stem cell transplantation in high-risk breast cancer.

고봉주,양명정 효성여자대학교 가정대학 학도호국단 1986 家政大論集 Vol.5 No.-

가열유가 흰쥐의 혈청 및 간장의 효소에 미치는 영향을 알아보기 위해 산가 2.10인 기름(HA군)과 산가 4.02인 기름(HB군)을 각각 경구투여하여 3주간 및 6주간 사육한 후 혈청 및 간장에서의 Al-Pase활성 변동을 관찰하였다. 1. 간장 무게는 대조군에 비해 가열유를 투여한 두 군 모두 높았으며 그중에서도 HB군이 더 높았다. 2. 혈청Al-Pase활성은 대조군에 비해 가열유를 투여한 HA, HB군 모두 증가하였고 투여 기간별로 비교하였을 때는 3주보다 6주에서 더 감소하였다. 3. 간 조직 Al-Pase활성은 대조군에 비해 HA군은 유의적 차이가 없었으나 HB군은 현저한 증가를 보였고 투여 기간별로는 3주보다 6주가 다소 감소하였음을 알 수 있다. To study effect of heated oil on the enzyme activity in the rat serum and liverrats were fed 3 and 6 weeks by intubating oils heated for acid value 2. 10(HA group) and acid value 4.02 (HB group). The alkaline phosphatase activity changes of the serum and liver tissue were observed. Average liver weiget the contents were all in creased HA and HB group by intubating oils heated, The compared the HA group with the HB group was heavier thanHA group. The serum alkaline phosphatase activities the control group were all increased HA and HB group by intubation oils healed. During the oil feeding period, the activities of alkaline phosphatase were decreasedin the 6 weeks than in 3 weeks. In the liver tissue, the alkaline phosphatase activity the contents not sinificantly different but was very increased in the HB group. During the oil feeding period, the liver alkaline phosphatase activity were decreasedin the 6 weeks than in 3 weeks.

주정중독 환자에서 Fluoxetine이 혈중 알콜 농도와 음주효과에 미치는 영향

김명정,박제민,정봉주 大韓神經精神醫學會 1994 신경정신의학 Vol.33 No.1

The effect of chronic administration of fluoxetine on blood alcohol concentration and on a number of alcohol induced physical and psychological effects was studied. The subjects were 14 hospitalized alcoholics without significant depression. After 21 days of 60mg daily fluoxetine and placebo administration. 2.5ml/kg body weight of 40% alcohol was administrated in a single dose and blood alcohol concentrations were measured 10, 20, 40, 60, 120, and 240min, after the alcohol intake. Mania Rating Scale score(MRS), pulse rate, respiratory rate and subjective physical condition were measured before and 30min, after alcohol intake. The results were as follows: 1) Blood alcohol concentrations were significantly higher after fluoxetine administration than placebo administration at 40min, and 60min, after alcohol intake. 2) Fluoxetine suppressed the increase of pluse rate induced by alcohol intake. However, no significant difference was noted in the alcohol induced changes in the scores of MRS, respiratory rate, and subjective physical condition between the drug and placebo administrations. 3) After fluoxetine administration, a significant negative correlation was shown between blood alcohol concentration, 10min after alcohol intake and MRS. In contrast, however, a significant positive correlation was seen between the two variable after placebo administration. From these results, it is suggested that fluoxetine increases blood alcohol concentration only during higher alcohol concentration and that the reduction of alcohol intake after chronic administration of fluoxetine may be due, at least in part, to an attenuation of positie reinforcement of alcohol effect, rather than to an enhancement of the aversion reaction to alcohol.
