저자 등은 기존의 치료에 반응하지 않은 중증 허혈성 지체질환 환자를 대상으로 하여 vascular endothelial growth factor를 이용한 혈관신생 유전자 치료를 시행하였다. 치료 후 환자의 허혈에 의한 하지 통증이 현격하게 감소하고 상처의 진행이 측부혈관이 많이 증가됨이 관찰되어 이에 문헌고찰과 함께 보고하는 바이다. We report VEGF-induced angiogenic gene therapy in a patient with critical limb ischemia, who did not respond to conventional treatment. This patient was the first case in a dose-escalating series of phase I clinical trial. The patient had severe resting pain, gangrene and diffuse ulcer in his left foot. Total 1,000㎍ of naked DNA encoding human VEGF165 was administered intramuscularly to 8 sites of the loft lower extremity. Four weeks after the first 1,000㎛ was administered to the same sites (total dose: 2,000㎛). After gene therapy, resting pain gradually reduced and the amount of analgesics taken by the patient decreased. The ischemic wound of lower extremity slightly improved. However, there was no complete wound healing at 12 weeks of treatment. Digital subtraction angiography at 12 weeks after gene therapy showed an increase in collateral vessels at the mid-tibial, ankle and foot arch levels. Immediately and up to 12 weeks, there was no complication related to gene therapy. These findings may be cautiously interpreted to indicate that intramuscular injection of naked plasmid DNA of VEGF_165 may induce therapeutic angiogencsis in a patient with critical limb ischemia. Further clinical evaluation of VEGF-induced gene therapy is needed to evaluate the safety and efficiency of this treatment.(Korean J Med 64:85-90, 2003)

Objective. Productivity loss was compared by 3-stage of disease activity and associations between higher disease activity and high productivity loss were identified. Methods. Data were extracted from Rheumatoid Arthritis (RA) Patient-reported Outcomes Research, which enrolled 2,000 RA patients (>20-year) on disease-modifying-antirheumatic-drugs (DMARDs) (≥ 6-month) from December 2012 to June 2013. This included 1,457 RA patients with the disease activity score (DAS-28-ESR) in their medical charts. Productivity loss in time and indirect cost was estimated using The World Health Organization Health and Work Performance Questionnaire (HPQ). Baseline characteristics and productivity loss outcomes were compared according to DAS-28-ESR groups. Results. 84.4% were females, 54.2% had low DAS-28-ESR (<3.2), and 38.2% and 7.6% had moderate (3.2∼5.1) and high DAS-28-ESR (>5.1). Patients with moderate to high DAS-28-ESR had higher lost productivity time (LPT) and monthly costs of LPT than those with low DAS-28-ESR (time in hours: 110.0±58.4 vs. 132.4±57.2 vs. 71.5±52.0, p<0.0001; monthly costs of LPT in 1,000 Korean won: 1,097±607 vs. 1,302±554 vs. 741±531, p<0.0001). Multiple regression analyses revealed significant associations with high LPT in high (adjusted odds ratio [OR]=3.87, 95% confidence interval [CI]: 2.18∼6.87) and moderate DAS-28-ESR (adjusted OR=1.88, 95% CI: 1.41∼2.52) compared to low DAS-28-ESR. In addition, positive associations with high monthly costs of LPT were observed in high (adjusted OR=3.45, 95% CI: 1.98∼5.99) and moderate DAS-28-ESR (adjusted OR=1.93, 95% CI: 1.43∼2.54) compared to low DAS-28-ESR. Conclusion. Timely therapeutic strategies should be taken into consideration given that the RA patients with moderate to high DAS-28-ESR showed strong associations with high productivity loss for effective management of RA.

This research was conducted to obtain basic data with regard to the heating performance that would be produced by installing an aluminum hot water pipe inside the greenhouse with the goal of reducing the heating energy in greenhouse. The research results are summarized as follows. The degree of difference in relation to the temperature by height within the greenhouse during the entire experiment was significant - within the range of 4.0~7.0℃. The temperature difference between incoming and outgoing water was about 3.3℃ greater when FCU was activated compared to when it was not activated. Meanwhile, the amount of energy consumed increased about 36.2~40.1%. The amount of pyrexia per hour also increased by 44.6~52.0%. During the experiment period, circulated flux was within the range of 0.48~0.49 L · s<SUP>?1</SUP> while average fluid speed was 1.53~1.56 m · s<SUP>?1</SUP>. The average temperature difference between incoming and outgoing water was 6.24~11.50℃. The amount of heating value by each set temperature within the minimum outdoor temperature range of ?14.0~?0.6℃ was 135,930~307,150 ㎉, and the range was within the 9,610~19,630 ㎉ · h<SUP>?1</SUP> per hour. This demonstrated that about 23~53% heating energy of the maximum heating load could be supplied. Total radiating value and amount of energy consumed were 2,548,306 ㎉ and 3,075.7 ㎾h, respectively. When heating takes place using oil, which is a fossil fuel, the total amount of light oil consumed was 281.6 L while the cost was 321,000 won. When the electricity cost for farms is applied, the total cost was about 110,730 won, which is about 33.5% of the cost required compared to oil consumption. The temperature at in the experiment area was about 8.3~14.6℃ higher compared to that of the control area.

Invasive pulmonary aspergillosis is known to have a poor prognosis and major cause of morbidity and motality in patients with hematologic disease. Without adequate therapy, invasive pulmonary aspergillosis will almost always progress to fatal pneumonia. Early administration of antifungal agents in patient with invasive pulmonary aspergillosis is most important. And surgical resection of aspergillous-infected tissue may be useful in patients with lesions that are contiguous with great vessel and lesions causing hemoptysis. We reported a rare case of surgical resection as curative treatment for invasive pulmonary aspergillosis patient in 58-year-old man who had the history of acute myeloid leukemia.

대형 프로젝트 수주를 위해서는 기획·관리능력뿐만 아니라 건설업체의 금융조달능력이 필요하다. 프로젝트 파이낸싱은 단일금융기법이 아닌 복합적이고, 다양한 이해당사자가 관련된 자금조달기법이므로 그 관계당사자중 한 부분의 노력만으로는 성공할 수는 없다. 정부와 금융기관이 협조를 강화하고, 특히 정부차원에서 지원정책과 규제 완화조치로 지원을 개선하는 노력이 필요하다. 이에 국내 건설업체도 프로젝트 파이낸싱의 도입을 건설 수주를 위한 하나의 수단으로만 받아들이는 오류를 피하고 국내외 건설환경을 분석·대응하는 등의 적절한 대처가 요구되며, 기술경쟁력뿐만 아니라 건설관리능력과 자금조달에 관련하여 프로젝트 파이낸싱의 필요성을 인식하고 연구하여 활용하도록 해야 한다. Receiving a major project order requires not only planning and management but financing capability of construction companies. Since project finance is multi-complex financial supply method by various parties concerned not a single supply method, it can not succeed with one part's effort. It is also necessary to reinforce the relationship between the governments and financing companies, especially the support and regulation relax policy by the governments. As such, domestic construction companies should not consider induction of project finance as a means of acceptance a construction environment in domestic and overseas. And also it is necessary to apply in the field which researched about technology competitiveness, construction management capability and financial supply.

동동주, 청맥 농축물의 투여가 흰쥐의 성장률, 혈청 효소활성 혈청 지질에 미치는 영향을 조사하였다. 실험동물의 체중 증가량은 동동주, 청맥 농축물의 농도별 투여가 대조군과 비슷한 경향을 나타내었으므로, 동동주, 청맥의 투여가 성장률에 지장을 주기 않음을 알 수 있었다. 총 콜레스테롤 함량, 중성지질 함향은 DD1군과 CM1군에서 대조군 보다 낮은 경향을 나타냈고, LDL함량은 DD1군에서 대조군 보다 낮은 경향을 나타냈다. 이러한 결과로부터 동동주 8g/kg 투여는 25%(v/v) 에탄올 5g/kg/day 경구 투여가 만성중독을 일으킬 수 있는데 반해 혈중 지질 함량을 감소시키므로 혈중 중성지질 농도 증가로 인한 심질환 예방에 기여 할 것으로 사료된다. Makkoli is a traditional and general alcoholic beverage in Korea. It's brewed from rice, shows an alcohol concentration of about 16%, has a characteristic fragrance, is slightly acidic, and has a sweet taste. Recently, taking these tradition alcoholic beverages are decreased. We examined the effect of Dongdongju and Cheongmaek kinds of Makkoli on serum enzyme activity and lipid concentration in rats. Sparague-Dawley rats were randomly assigned to groups as follows: control group, Dongdongju 8g/kg administered group(DD1), Dongdongju 1.6gkg administered group(DD2), Dongdongju 0.8g/kg administered group(DD3) and Cheongmaek 8g/kg administered group(CM1), Cheongmaek 1.6g/kg administered group(CM2), Cheongmaek 0.8g/kg administered group(CM3). Experimental diets were fed for 6 weeks. The body weight gain, seram enzyme activity and serum lipid values of all groups were compared with control group. There were no differences in growth. Alkaline phosphatase and GPT activities of DD3 and CM2 were lower than control group, but no significant differences. The total cholesterol concentrations of DD1 and CM1 were lower than that of control group. The triglyceride concentration of DD1 and CM1 was the same as results of total cholesterol concentration. These results suggest that Dongdongju and Cheongmaek positively influenced on serum lipid concentration.
