      • 트레드밀 운동이 청소년의 혈중지질에 미치는 영향

        정현홍,양정옥,유창재 신라대학교 자연과학연구소 2006 自然科學論文集 Vol.15 No.-

        The purpose of this study was to examine the effects of treadmill exercise on adolescents serum lipids. This study was a simple pre- and post-test design. The participants of this study were 7 middle-school students located in a metropolitan city, Korea. All participants were boys (mean age=15.81 years; SD=.36), and were treated as a experimental group. A 12-week treadmill exercise program (60 min. & 3 times per week) was implemented. To collect blood samples and analyze TG, TC, HDL-C, and LDL-C, the Becton Dickison Vacutainer System was used. Results revealed that the participants' TG, TC, LDL-C were significantly decreased after the program. However, no significant differences were found in HDL-C even though there was an increase after the program. It was concluded that a 12-week treadmill exercise program can be as effective as other types of aerobic exercise in improving adolescents' serum lipids. Recommendations for future research and practice were provided.

      • S.D. Rats를 이용 1, 1-Dichloro-1-fluoroethane의 아민성 흡입독성 연구

        김현영,이성배,임철홍,김철우,점용현,한정희,전윤석,최수영,강대봉,이용묵 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.1

        There were no specific effects for test materials on Sprague-Dawley (S.D.) rats in clinical symptoms, amounts of food intakes, weight changes, laboratory findings, and pathology after whole body l, l-Dichloro-1 -fluoroethane (used as coolant, metal cleaner and solvents) exposure(0, 1,500, 3,000, and 6,000 ppm) for 13 weeks (6 hour/day, 5 days/week). However, the loss of capillary vessels in eyeball (pupil) was observed in a female rat among 6,000 ppm group. Though there was a tendency for MCHC (Mean Corpuscular Hemoglobin Concentration) in rat to be decreased (p<0.05), it was not regarded as abnormal because the values were within normal limits. In asthma-stimulation related evaluations, there was also a tendency for inflammatory cell counts in bronchoalveolar lavages to be increased. But it had no statistical significance, and also no dependency on sex and the exposed concentration. Based on this result, the non observed effect level (NOEL) induced by 1, 1-Dichloro-l -fluoroethene inhalation was evaluated in groups with 3,000 ppm below (S .D. Rats, 13 weeks). Finally, it was concluded that the short term exposal of 1, 1-Dichloro-l-fluoroethane is not considered as a asthma stimulant by inhalation despite of some study limitations such as test animals use and short-term exposure .

        만성 정신분열증 환자의 인지기능에 미치는 Clozapine 효과

        이홍식,정미정,김지현 大韓神經精神醫學會 1994 신경정신의학 Vol.33 No.5

        Objects : Prior reviews have indicated that antipsychotic drugs may impair planning ability and memory but otherwise may even improve attention and reaction time performance. This study was performed to evaluate the effect of clozapine on cognitive functions and psychopathology in chronic schizophrenic patients. Methods : Neuropsychological tests such as Wisconsin Card Sorting test, Digit Span test and Judgment of Line Orientation test were applied to 21 chronic schizophrenic patients and 15 normal controls. The schizophrenic patients were retested with the same instruments after 3 monthes of treatment period with clozapine. Psychopathology was assessed in the same patients before initiation of clozapine and at 12 weeks using BPRS. Results : Cognitive impairment was found in each measure of executive function, attention, short-term memory and visual perception ability as compared with the normal controls. After 12 weeks of clozapine treatment, signigicant improvement occured in attention, short-term memory and visual perception ability as well as psychotic symptoms including both positive and negative symptoms, but had little effect on executive functions. Conclusion : Short-term treatment with clozapine may possibly improve parts of cognitive functions of chronic schizophrenics, and these effects can contribute to increase capacity for work and social function.

        소목(Caesalpinia sappan) 추출물의 Streptococcus mutans에 대한 성장, 산생성, 부착 및 비수용성 글루칸 합성 억제에 미치는 영향

        유용욱,유현희,김윤정,유미선,서세정,이황,이흥수 대한구강보건학회 2003 大韓口腔保健學會誌 Vol.27 No.2

        Streptococcus mutans is known as the causative bacterial playing the most important role in forming plaque and it is being noticed as major causative bacteria of dental caries. Therefore, development of more effective, substantial and safe preventive agent against dental caries and periodontal disease is honestly required. The present study was designed to investigate the effect of chloroform extract(CE), n-butanol extract(BE),methanol extract(ME) and water extract(WE) of Caesalpinia on the growth, acid production, adhesion, and insoluble glucan synthesis of Streptococcus mutans. The CE, BE, ME and WE decreased the growth and acid production of S.mutans than that of control, especially, the ME was more effective than other extracts. The effect of CE, BE, ME and WE on the adherences to saliva-coated hydroxyapatite bead(S-HA) were evaluated. At the concentration of 2,000 ㎍/㎖, the CE showed 32% rate of bacterial adherence to S-HA, whereas, other extracts of the same concentration producedgreater than 50% rate. The CE and BE were significantly decreased the reduction rates of water insoluble glucan formation from sucrose by crude glucosyltransferase of S.mutans. Thus, the application of C. sappan can be considered a useful and a practical method for the prevention of dental caries.

        대퇴동맥을 통한 경피적 관동맥 중재시술 환자의 천자부위 지혈을 위한 Angioseal^(�) 사용과 고식적 용수 압박법의 비교 : 전향적 연구

        김용훈,권현철,김필호,안석진,유철웅,최진호,이상철,김준수,김덕경,전은석,이상훈,홍경표,박정의,서정돈 대한내과학회 2004 대한내과학회지 Vol.66 No.5

        목적 : 경피적 관동맥 중재술은 최근 양적 및 질적으로 급격한 발전을 보였지만 시술 시 천자부위의 혈관 합병증은 아직 해결해야 할 문제점이다. 저자들은 대퇴동맥을 통한 경피적 관동맥 중재술을 환자에게 천자부위 지혈을 위한 혈관폐쇄기구인 안지오실의 안전성과 유용성을 고식적인 용수 압박법과 비교 연구하고자 하였다. 방법 : 2002년 4월부터 2003년 5월 사이에 삼성서울병원 심장혈관센터에서 대퇴동맥을 통한 경피적 관동맥 중재술을 성공적으로 시행한 200명의 환자(안지오실 사용군: A군, 100명, 고식적 용수압박법 사용군 B군, 100명)를 대상으로 시술 후 주요 합병증 및 경한 합병증, 지혈 후 환자가 자리에 앉기까지의 시간, 보행개시 가능시간, 총 재원 기간과 시술 1주 후의 합병증을 전향적으로 조사하여 비교 연구하였다. 결론 : 두 군에서 연령, 성별, 기저질환, 심혈관 질환의 위험요소, 시술의 종류, 시술 중 사용한 헤파린의 양, clopidogrel의 양, ticlopidine의 양, 지혈 시 수축기와 확장기혈압, ACT (activated clotting time)는 차이가 없었다. A군이 B군에 비해 시술 후 자리에 앉기까지의 시간 (A군: 4.3±0.3시간, B군: 13.7±0.8시간, p=0.004) 및 보행개시까지의 시간(A군: 6.8±0.5시간, B군: 18.8±2.1시간, p=0.013)이 유의하게 짧았다. 시술 후 주요 합병증은 두군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 A군에서 유의하게 적었다(A군: 28명, B군: 19명, p=0.003). 반상출혈의 경우는 A군에서 유의하게 낮았지만(A군: 3명, B군: 12명, p=0.01), 혈종, 출혈의 발생은 두군간에 차이가 없었다. 총 재원기간에는 두 군간에 차이가 없었다(p=0.239). 시술 1주 후 경과관찰에서 주요합병증은 역시 두 군 모두에서 관찰되지 않았으며, 경한 합병증의 전체발생은 두 군에서 차이가 없었다(A군: 15명, B군: 13명 p=0.418), 반상출혈의 빈도는 차이가 없었지만 혈종의 발생은 A군에서 더 낮았다(A군: 2명, B군:6명, p=0.004). 두 군 모두에서 출혈은 발생하지 않았다. 결론 : 대퇴동맥을 통한 경피적 관동맥 중재술을 시행한 환자에서 안지오실의 사용은 고식적 용수 압박법에 비해 환자의 침상 안정시간을 줄여 조기 활동개시가 가능하게 하였으며 국소합병증의 위험도를 일부 낮추어, 시술에 따른 환자의 불편을 현저하게 감소시킬 수 있다고 할 수 있을 것으로 기대된다. Background : Although the number and the quality of percutaneous coronary intervention have been recently increased dramatically, the vascular complication at puncture site is still the major cause of patients' morbidity. We evaluated the safety and efficacy of newly of newly-developed collagen-based arterial closure device, Angioseal after transfemoral percuatenous coronary intervention. Methods : This study was designed as a prospective single center non-randomized comparative study. A total 200 patients undergoing transfemoral percutaneous coronary intervention were enrolled between April 2002 and May 2003. They were divided into two groups; Angioseal group (group A, n=100) and manual compression group (group B, n=100). The baseline clinical and angiographic characteristics were reviewed. The time to sit up, the time to ambulation, the duration of hospital stay, major and minor vascular puncture site complications were monitored. The patients were followed-up for 1 week after procedure by telephone. Results : The baseline clinical characteriwtics, clinical diagnosis, cardiocascular risk factors, typesof procedure, doses and numbers of anticoagulants were similar between two groups. The blood pressure and activated clotting time were also similar. The time to sit up (group A: 4.3±0.3 hours, group B: 13.7±0.8 hours, p=0.004) and the time to ambulation (group A: 6.8±0.5 hours, group B: 18.8±2.1 hours, p=0.013) were shorter in group A. No major vascular complications were noted. The incidence of hematoma and bleeding were not significantly different between two groups. The incidence of ecchymosis, however, was significantly lower in group A (group A:12%, group B: 3%, p=0.001) The duration of gospital stay was similar between groups. During 7 days of follow-up period incidence of hematoma was significantly lower in group A (p=0.004). Although the incidence of ecchymosis was not significantly different between two groups. Conclusion : The angioseal may be associated with earlier ambulation and less patients' morbidity with low incidence of local complication rate compared to manual compression after transfemoral percutaneous coronary intervention.

      • G-CSF로 체내 증폭된 골수를 이용한 동종 조혈모세포이식

        이종욱,김정아,민창기,김희제,엄현석,박수정,서정곤,김동욱,홍영선,민우성,김춘추,김동집 대한조혈모세포이식학회 1998 대한조혈모세포이식학회지 Vol.3 No.2

        연구배경: 이식시 주입되는 골수세포수는 생착 속도 및 생존율과 밀접한 관계가 있으나, 임상적으로 환자의 체중이 공여자에 비해 지나치게 많을 때 단위 체중당 환자에게 주입되는 세포의 양이 적어 문제가 될 수 있다. 방법: 저자들은 가톨릭 조혈모세포이식 센터에서 동종 골수이식을 시행한 환자들 중 환자의 체중이 공여자에 비해 10kg이상 많은 경우 골수 채취 전에 공여자에게 3일간 피하로 G-CSF(10ug/kg/day)를 투여하여 골수를 체내(in vivo) 증폭시킨 후 골수이식을 시행한 25예의 환자를 대상으로 고식적인 방법으로 골수이식을 시행한 위험인자가 일치되는 대조군과 비교하여 이식된 세포수, 혈구의 회복속도 및 이식편대 숙주반응(GVHD)의 발생율, 그리고 생존율 등을 비교 분석하였다. 결과: 단기간의 G-CSF 투여로 증폭된 골수의 총 유핵세포수, 단핵구수는 대조군에 비해 3-5배, CD34 + 세포수는 6배 증폭되었으며, 두 군간에 세포의 면역표현형(CD4, CD5, CD7, CD8, CD20)의 차이는 없었다. 중성 백혈구 수가 0.5×10^(9)/L 이상 회복되는 시기는 두 군간의 차이가 없었으나(15.5일 vs 16일; p=0.131), 혈소판 수가 30×10^(9)/L 이상으로 회복되는 시기는 G-CSF 투여군에서 의의있게 단축되었다(20일 vs 26일; p=0.013). 두 군간 급성 및 만성 GVHD의 발생률과 정도의 차이는 없었으며, 이식 후 재발 및 생존율의 차이도 없었다. 결론: 이식전 공여자에게 단기간 G-CSF를 주사하여 생체내에서 골수 조혈모세포를 증폭시킨 후 이식하는 방법은 공여자와 환자의 심각한 체중 차이로 인해 단위체중당 이식되는 조혈모세포양이 부족한 환자들에게 안전하고 유용한 방법일 뿐만 아니라 GVHD의 증가 없이 빠른 혈구회복을 기대할 수 있는 이식기법이라고 생각한다. 향후 증폭된 골수 조혈모세포의 특성 연구 및 이의 효용성을 확인하기 위한 전향적인 연구가 필요하리라고 생각된다. Background: Sufficient stem cell doses are necessary to overcome engraftment failure in allogeneic bone marrow transplantation(BMT). Cell doses harvested may depend on body weight (BW) difference between donor and recipient. In practice, it is important to achieve large number of stem cells from donor who were lower BW than that of recipient. Methods: We have tried to inject G-CSF(10ug/kg/day) subcutaneously for 3 days to the allogeneic donor with lower BW than recipient before harvest to increase BM inoculum. BM was infused into patients without any manipulation on day 5. A total 25 patients were enrolled; 12 AML, 6 ALL, 5 SAA and 2 CML(expansion group). We compared the expansion group with 25 historical control patients, matched for diagnosis and clinical characteristics, who underwent unprimed BMT. Results: Recipient BW is not different between the expansion and control group. However, allogeneic donors in the control group weigh heavier than those in the expansion group. The yield of TNC, MNC, and CD34^(+) cells from G-CSFprimed BM was significantly higher than that from unprimed BM. There was no difference in immunophenotyping analysis(CD4, CD5, CD7, CD8, CD20) between two groups. The median time reaching to absolute neutrophil count more than 0.5×10^(9)/L was not different(15.5 vs 16 days: p=0.131), but time to platelet recovery more than 30×10^(9)/L was significantly shorter for the patients who received G-CSF-primed BM (20 vs 26 days: p=0.013). There was no difference in the incidence of acute and chronic GVHD, relapse rate and overall survival between the two groups with a median follow-up of 13 months. Conclusion: These data suggest that the short-term administration of G-CSF to an allogeneic donor prior to BM harvest seems to be a feasible method to achieve an adequate number of cell doses for patients who weigh higher than donors. Randomized, prospective study is needed to evaluate the efficacy of allogeneic BMT using in vivo expansion of BM by G-CSF.
