<P>Maitotoxin (MTX) is known as one of the most potent marine toxins involved in Ciguatera poisoning, but intracellular signaling pathways caused by MTX was not fully understood. Thus, we have investigated whether intracellular reactive oxygen species (ROS) are involved in MTX-induced cellular responses in human umbilical vein endothelial cells. MTX induced a dose-dependent increase of intracellular [Ca(2+)]. MTX stimulated the production of intracellular ROS in a dose- and time-dependent manner, which was suppressed by BAPTA-AM, an intracellular Ca(2+) che-lator. Ionomycin also elevated the ROS production in a dose-dependent manner. MTX elevated transamidation activity in a time-dependent manner and the activation was largely inhibited by transfection of tissue transglutaminase siRNA. The activation of tissue transglutaminase and ERK1/2 by MTX was sup-pressed by BAPTA-AM or ROS scavengers. In addition, MTX-induced cell death was significantly de-layed by BAPTA-AM or a ROS scavenger. These results suggest that [Ca(2+)]-dependent generation of in-tracellular ROS, at least in part, play an important role in MTX-stimulated cellular responses, such as activation of tTGase, ERK phosphorylation, and in-duction of cell death, in human umbilical vein endothelial cells.</P>

Song, Jung Sub,Jang, Jie Young,Shinn, Kyung Sub,Lee, Sun Hee,Choi, Ihl Bhong,Kim, In Ah,Kang, Ki Mun,Park, Jae Gil,Kuak, Mun Sub THE CATHOLIC UNIVERSITY OF KOREA 1997 Bulletin of The Catholic Research Institutes of Me Vol.25 No.-

This study was tried to evaluate the potential benefits of concurrent chemoradiation therapy(low dose daily cisplatin combined with split course radiation therapy) compared with conventional radiation therapy alone in stage Ⅲ non-small cell lung cancer. The end points of analyses were response rate, overall survival, survival without locoregional failure, survival without distant metastasis, prognostic factors affecting survival and treatment related toxicities. Between April 1992 and March 1994, 32 patients who had stage Ⅲ non-small cell lung cancer were treated with concurrent chemoradiation therapy. Radiation therapy for 2 weeks (300 cGy given 10 times up to 3000 cGy) followed by a 3 weeks rest period and then radiation therapy for 2 more weeks(250 cGy given 10 times up to 2500 cGy) was combined with 6㎎/M^2 of cisplatin. Follow-up period ranged from 13 months to 48 months with median of 24 months. Historical control group consisted of 32 patients who had stage Ⅲ non-small cell lung cancer were received conventionally fractionated(daily 170-200 cGy) radiation therapy alone. Total radiation dose ranged from 5580 cGy to 7000 cGy with median of 5940 cGy. Follow-up period ranged from 36 months to 105 months with median of 62 months. Complete reponse rate was higher in chemoradiation therapy(CRT) group than radiation thernpy(RT) group(18.8% vs. 6.3%). CRT group showed lower in-field failure rate compared with RT group(25% vs. 47%). The overall survival rate and no significant differences in between CRT group and RT group(17.5% vs. 9.4% at 2 years). The survival without locoregional failure (16.5% vs. 5.3% at 2 years) and survival without distant metastasis(17% vs. 4.6% at 3 years) also had no significant differences. In subgroup analyses for patients with good performance status(Karnofsky performance scale≥80), CRT group showed significantly higher overall survival rate compared with RT group(62.5% vs. 15.6% at 2 years). The prognostic factors affecting survival rate were performance status and pathologic subtype(sqamous cell cancer vs. nonsquamous cell cancer) in CRT group. In RT alone group, performance status and stage (Ⅲa vs. Ⅲb) were identified as a prognostic factors. RTOG/EORTC grade 2-3 nausea and vomiting(22% vs. 6%) and bone marrow toxicities(25% vs. 15.6%) were significantly higher in CRT group compared with RT alone group. The incidence of RTOG/EORTC grade 3-4 pulmonary toxicity had no significant differences in between CRT group and RT group(16% vs. 6%). The incidence of WHO grade 3-4 pulmonary fibrosis also had no significant differences in both group(38% vs. 25%). In analyses for relationship of field size and pulmonary toxicity, the patients who treated with field size beyond 200㎠ had significantly higher rates of pulmonary toxicities. Conclusions: The CRT group showed significantly higher local control rate than RT group. There were no significant differences of survival rate in between two groups. The subgroup of patients who had good performance status showed higher overall survival rate in CRT group than RT group. In spite of higher incidence of acute toxicities with concurrent chemoradiation therapy, the survival gain in subgroup of patients with good performance status were encouraging. CRT group showed higher rate of early death within 1 year, higher 2 year survival rate compared with RT group. Therefore, to evaluate the accurate effect on survival of con- current chemoradiation therapy, systematic follow-up for long termsurvivors are needed.

분석심리학적 관점에서 본 동의보감의 정신치료

본 연구는 Jung의 분석심리학적 관점에서 동의보감의 병리와 치료원리를 탐구한 연구이다. 연구 결과, 분석심리학의 핵심 개념인 대극의 원리가 동의보감을 관통하는 기본적인 철학임을 알 수 있고, 동의보감에 나타난 정신치료 원리는 3가지로 구분할 수 있다. 첫째, 정신의 작용은 에너지 균형과 순환을 나타내는 소장평형(消長平衡)의 원리로 모든 우주 만물이 형태나 성격이 바뀔 뿐 에너지는 사라지지 않고 균형을 이루는, 대극의 초월과 합일을 통해 계속 순환하는 만물의 생성과 소멸의 원리이다. 둘째, 정신병리는 대극의 불균형을 극복하려는 물극필반(物極必反)의 원리로 에너지가 한쪽으로 치우쳐 불균형이 심화되면 다시 반대쪽으로 에너지가 기울게 된다는 상호작용의 원리이다. 정신병리는 불균형을 만드는 에너지의 일방성과 에너지의 상호작용의 부재 및 부조화, 들고나는 에너지의 속도 차이에 의해 초래된다. 셋째, 정신치료는 불균형에서 조화와 균형을 회복하는 것이며 치우침 없이 균형을 유지하는 중화(中和)의 원리로 설명한다. 중화는 신체뿐만 아니라 정신의 에너지 불균형을 다루는 정신치료 원리이며, 이는 마음을 다스려 양생(養生)을 돕는 음평양비(陰平陽秘)와 대극의 균형과 합일을 통해 치료적 작용을 돕는 치이권형(治以權衡)으로 구분할 수 있다. 요컨대 동의보감은 정기신(精氣神) 대극(對極)의 상호관계 속에서 신체와 정신이 조화와 균형을 이루고 생리와 병리 및 치료의 원리를 다루고 있으며, 그 치료원리는 분석심리학적 관점의 대극의 합일과 개성화 과정으로 이해할 수 있다. 이를 통해 한의학의 치료에서 분석심리학을 기초로 한 개입 가능성을 살펴볼 수 있었다. The present study reviews the pathology and treatment principles of Donguibogam from the perspective of Jung’s analysis psychology in order to explore psychotherapy principles inherent in Donguibogam. The results indicate that the principle of opposing poles, a core concept of analytical psychology, is in line with Donguibogam. More specifically, three principles of psychotherapy are derived from Donguibogam. First, Sojangpyeonghyeong, a concept of the balance and circulation of energy, describes psychological functioning. Sojangpyeonghyeong, in which all things in the universe change only in forms or characteristics whereas their energy does not disappear but maintains its balance, is a principle of generation and extinction of things that circulate consistently through the unity and transcendence of two opposing poles. Second, Mulgeukpilban, a concept of overcoming the imbalance of opposing poles, accounts for psychopathology. It is a principle of interactions that, if energy is skewed to one side and its imbalance intensifies, the energy is tilted back to the other side. Psychological disorders develop if unilateral tendencies of energy create imbalance and occur from the absence and incongruity of interactions due to the confinement of energy and speed discrepancy in the ebb and flow of energy. Third, psychotherapy restores harmony and balance from imbalance, and is explained through JoongHwa, a concept of maintaining balance without bias. JoongHwa is a principle dealing with psychological as well as physical imbalances. It is categorized into two parts. One is Yinpyeongyangbi that helps protection from psychological disfunction. The other is Chiygwonhyeong, which helps therapeutic action through balance and unity of opposing poles. In summary, Donguibogam deals with the principles of physiology, pathology and treatment where the body and mind are harmonized and balanced in the mutual relationship of the Jung (精), Qi (氣) and Shin (神) polarities. The treatment principle could be interpreted as the unity and individualization of opposing poles from the perspective of analytical psychology. The findings implicate the plausibility of the psychotherapeutic application based on analytical psychology to the interventions of Korean medicine.

N/A Background: Repeated, long-term access of the vascular system is a prerequisite for successful extended care of the patients with end stage renal disease (=ESRD) treated with hemodialysis. Despite recent technical advances in percutaneous venous cannulation, vascular access remains a major problem in patients requiring acute Hemodialysis. Although the subclavian cannula has gained a large clinical acceptance in recent years, it carries specific risks such as hemothorax, pneumothorax, venus stenosis, thrombus formation and infection. Recently, a double-lumen, central venous catheter made of Silicone Rubber (=Perm cath) has developed for use as a vascular access device, This device is particularly useful in patients who have exhausted other vascular access sites or who have severe cardiovascular disease. Methods: A total of 23 dual-lumen silicone rubber catheters were placed through the internal jugular vein in 23 patients as a vascular access at our institution during the period of April, 1992 through November, 1992. The perm-cath (Hemocath, Quinton, Seattle) is 36 Cm long and each lumen has an internal diameter of 2 mm. Implantation of the catheters occurred in the operating room and under strict aseptic conditions through the right internal jugular vein. A 10 cm subcutaneous tunnel was then created, which extended from the in-cison to a point 2 cm above the ipsilateral clavicle. The catheter was passed out through the upper portion of the subcutaneous tunnel with the Dacron cuff placed 2 cm from the lower end of the tunnel, acting as both an anchor and a barrier to infection. The tip of the catheter was inserted through an internal jngular vein terminating in the right atrium under EKG monitoring. Each lumen of the catheter was filled with 1000 units of heparin sodium (1.5 ml in venous line, 1.5 ml in arterial line) and capped. Results : The mean duration of catheter use was 24±16 days (8 to 119 days), and the complication of perm-cath occurred in 3 cases such as venous thrombosis in 1 case, catheter exit site infection in 1 case, and exit site hematoma in 1 case. During hemodialysis, blood flow rate ranged from 190 to 313ml/min (mean:235±26ml/ min), and venous retrun pressure ranged from 20 to 150 mmHg(mean:65±16mmHg). Total 14 catheters were removed during treatment and the causes of catheter removal were patient death in 8 cases, venous thrombosis 1, recovery from acute rena1 failure 2, fistula maturation 2, infection 1. Conclusion: Internal jugular vein cannulation with silastic catheter which offers a new percutaneous method was provided safe and reliable as the temporary central vein access. The catheters are well tolerated by the patients and have the advantages of immediate use after placement, high blood flow rates, no repetitive venipuncture, and no cardiac dysfunction. Permcath is particulary useful in patients who have exhausted other vascular access site, severe cardiovascular disease, and terrified by repetitive venipuncture. Though our initial experience has been favorable, there will be needed to evaluate the outcome of permcath over longer period of time.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

The purposes of this study was to analyze the operational difference of foodservice center for homebound elderly by the presence of the dietitian. The questionnaire was developed to measure all variables for menu management and distributed to 103 meal service centers in charge of congregate meal service program and 57 centers for home-delivered meal service program. The data of 160 centers in charge of congregate meal service and home-delivered service centers were usable for analysis. Statistical data analysis was completed using the SAS 8.1 package program for descriptive analysis and chi-square test. Only 2 1.9% meal service centers had dietitians, what is more, they were not professionals who did menu management but foodservice managers, volunteers, cook or social workers. The current foodservice programs for the homebound elderly were operated without professional. In the part of menu management, dietitians were more actively involved in menu planning in the elderly foodservice center in the presence of the dietitians. The performance level of healthcare service was not significantly different, but the nutrition education in the elderly foodservice center with the dietitians was more frequently performed than that without the dietitians(p<0.05). In the food purchasing and food production management, the significant differences were shown that in the elderly foodservice centers in the presence of the dietitians, the proportion of the contract purchasing was significantly higher than that of direct purchasing(p<0.01). In food sanitaq management, the significant differences were not shown in the part of management of keeping meal for identifying the cause of food-borne illness and left-over, but the sanitation education for the foodservice employees was performed more frequently by the presence of the dietitians(p<0.01). In conclusion, the foodservice management was more systematically conducted in the elderly foodservice centers in the presence of the dietitians than that without dietitians. The elderly foodservice program has offered the health-related support for homebound elderly. Although there were several problems in elderly foodservice management, the program delivered well-targeted, effective, and efficient nutrition services and wide range of supportive service to the at-risk older population. It needs to be managed by professional for the improvement in the elderly foodservice.

Celay/In-Ceram, Conventional In-Ceram, Empress 2 전부도재관의 변연적합도에 관한 비교 연구

There have been many studies about marginal discrepancy of single restorations made by various systems and materials. But many of statistical inferences are not definite because of sample size, measurement number, measuring instruments. etc. The purpose of this study was to compare the marginal adaptations of the anterior single restorations made by different systems and to consider more desirable statistical methods in analysing the marginal fit. The in vitro marginal discrepancies of three different all-ceramic crown systems (Celay In-Ceram. Conventional In-Ceram. IPS Empress 2 layering technique) and one control group (PFM) were evaluated and compared. The crowns were made from one extracted maxillary central incisor prepared with a 1mm shoulder margin and $6^{\circ}$ taper walls by milling machine. 10 crowns per each system were fabricated. Measurements or a crown were recorded at 50 points that were randomly selected for marginal gap evaluation. Non-parametric statistical analysis was performed for the results. Within the limits of this study, the following conclusions were drawn: 1 Mean gap dimensions and standard deviations at the marginal opening for the maxillary incisor crowns were $98.2{\pm}40.6{\mu}m$ for PFM, $83.5{\pm}18.7{\mu}m$ for Celay In-Ceram, $104.9{\pm}44.1{\mu}m$ for conventional In-Ceram, and $45.5{\pm}11.5{\mu}m$ for IPS Empress 2 layering technique. The IPS Empress 2 system showed the smallest marginal gap (P<0.05). The marginal openings of the other three groups were not significantly different (P<0.05). 2 The marginal discrepancies found in this study were all within clinically acceptable standards ($100\sim150{\mu}m$). 3. When the variable is so controlled that the system may be the only one, mean value is interpreted to be the marginal discrepancy of a restoration which is made by each system and standard deviation is to be technique-sensitivity of each one. 4. From the standard deviations. the copy-milling technique (Celay/In-Ceram) was not considered to be technique-sensitive in comparison with other methods. 5. Parametric analysis is more reliable than non-parametric one in interpretation of the mean and standard deviation. The sample size of each group has to be more than 30 to use parametric statistics. The level of clinically acceptable marginal fit has not been established. Further studies are needed.
