Purpose : A randomized prospective study was conducted to compare the efficacy of early or late alternating schedules of radiotherapy, and carboplatin and ifosfamide chemotherapy in patients with limited-disease small cell lung cancer. Materials and Methods: From August 1993 to August 1996, a total of 44 patients with newly diagnosed, limited-disease small cell lung cancer, PS $H0\~2$, wt $loss<10\%$ were enrolled in a randomized trial which compared early alternating radiotherapy (RT)/chemotherapy (CT) and late alternating RT/CT. The CT regimen included ifosfamide $1.5\;g/m^2$ IV, d1-5 and carboplatin AUC 5/d IV, d2 peformed at 4 week intervals for a total of 6 cycles. RT (54 Gy/30 fr) was started after the first cycle of CT (early arm, N=22) or after the third cycle of CT (late arm, N=22) with a split course of treatment. Results : The pretreatment characteristics between the two arms were well balanced. The response rates in the early $(86\%)$ and late $(85\%)$ arm were similar. The median survival durations and 2-year survival rates were 15 months and $22.7\%$ in the early arm, and 17 months and $14.9\%$ in the late arm (p=0.47 by the log-rank test). The two-year progression free survival rates were $19.1\%$ in the early arm and $19.6\%$ in the late arm (p=0.52 by the log-rank test). Acute grade 3 or 4 hematologic and nonhematologic toxicities were similar between the two arms. Eighteen patients $(82\%)$ completed 6 cycles of CT in the early arm and 17 $(77\%)$ in the late arm. Four patients received less than 45 Gy of RT in the early arm and two in the late arm. There was no significant difference in the failure patterns. The local failure rate was $43\%$ in the early arm and $45\%$ in the late arm. The first site of failure was the brain in $24\%$ of the early arm patients compared to $35\%$ in the late arm (p=0.51). Conclusion : There were no statistical differences in the overall survival rate and the pattern of failure between the early and late alternating RT/CT in patients with limited-disease small cell lung cancer.

Purpose: This study was conducted to study the attitude of Korean lawyers toward withdrawal of life sustaining treatment, and compare and analyze different types of their attitudes. Methods: Research design of this project was Q methodology approach. The study population was 24 lawyers, aged from 32 to 69 years. Q sample to investigate the attitude of the lawyers toward withdrawal of life sustaining treatment included 34 statements obtained from literatures, TV debate, and depth interviews of 5 lawyers among the lawyers included. After listening to the purpose and method of the study, the 24 lawyers agreed to fill out a survey asking sociodemographic information, and the information was distributed in 9 scale Q-sample. Results: The collected data were processed through QUANL PC program and sorted into 5 types as follows: The first type was 'Choosing to withdraw life sustaining treatment', the second 'Withholding life sustaining treatment' regardless of the cost, the third is neutral type that claims that humans have the right to decide the death and life, and demands the proper legalization to protect such rights, the fourth type agrees to withdrawal of life sustaining treatment, nevertheless, admits that one has a rigt to withhold one's own life treatment, categorized as self contradiction type. The fifth type believed that 'Life and death are providential' with the faith, therefore, such authority to decide life and death belongs to God, but not human beings. Conclusion: In conclusion, the lawyer's attitudes toward withdrawal of life sustaining treatment were grouped into five different types as follows: 'Choosing to withdraw life sustaining treatment', 'Withholding life sustaining treatment', 'Demanding legalization', 'Self contradiction type', and 'Life and death are providential'.

당뇨병은 고대 에집트시대때부터 다뇨증상을 가진 질병으로 알러져 왔으며 희랍의 의사인 Aretaeus (of Cappadocia)가 이 질병을 희랍어로 siphon을 의미하는 diabetes라 명명하였다. 17세기에는 꿀을 뜻하는 mellitus가 diabetes에 더해져 지금까지 쓰이고 있으며 18세기에 들어서야 sweetness가 sugar에 기인한다는 걸 밝혀내었다. 당뇨병은 이와 같이 오래되고 흔한 질병이지만 그에 대한 치료제는 insulin, sulfonylurea제, biguanide제 그리고 최근에 개발되어 시판되었으나 간독성으로 인하여 영국에서는 판매가 금지된 thiazolidinedione제 뿐이기 때문에 많은 제약회사에서 새로운 치료제를 개발하기 위하여 치열한 경쟁을 하고 있다. 이는 전세계적으로 1억명 이상 그리고 미국에만 1,400만명 이상의 당뇨병 환자가 있다고 추정되며 이의 치료에 들어가는 경비가 $105억에 달하기 때문이기도 하다. 또한 주로 선진국에서 흔하던 이 질병이 요즈음엔 풍족해진 음식, 문명의 서구화(소위 말하는 "Coca-colonization")와 운동 부족 등의 이유로 개발국과 개발도상국에서도 발병율이 높아 가는 질병이기 때문에 획기적인 치료제의 개발이 절실히 필요한 때이기도 하다.한 때이기도 하다.

Background: Tissue-type plasminogen activator is a physiologic activator, which has high affinity for fibrin and is activated by fibrin. Because of these properties, t-PA has the potential to induce effective thrombolysis without producing a systemic lytic state. In practice, however, therapeutically efficacious doses of t-PA has been associated with the development of a systemic lytic state. As experience with t-PA has accumulated, it has suggested that the fibrin selectivity is influenced by the dose and duration of t-PA infusion, and many studies have performed in an attempt to optimize the duration of t-PA regimen. Methods: This study was designed to assess the thrombolytic efficacy of t-PA and the differences of two dosing regimens of t-PA (infusion of 1 mg/kg t-PA over 15 or 180 minutes) in a canine model of pulmonary embolism, induced by injection of radioactive autologous blood clots. By continuously counting over both lung fields with a external gamma counter, we correlated rate and extent of pulmonary thrombolysis with corresponding pulmonary hemodynamics in addition to the gas analyses of arterial and mixed venous blood. Results: 1) While total clot lysis was similar ($36.2{\pm}3.3%$ and $39.6{\pm}2.3%$ respectively, p>0.05) when t-PA was infused over 15 or 180 minutes, the rate of lysis during infusion was markedly increased with the shorter infusion ($81.4{\pm}16.8%/hr$ vs $37.3{\pm}2.4%/hr$, p<0.05). 2) The duration of thrombolysis was $63.3{\pm}22.2$ minutes although t-PA was administered over 15 minutes, and it was only $148.5{\pm}14.0$ minutes in case of the infusion over 180 minutes (p<0.05). 3) The increased rate of thrombolysis with the shorter infusion was accompanied by a faster amelioration of cardiopulmonary impairment from pulmonary embolism (p<0.05). Conclusion: It is concluded that the shorter (15 minutes) infusion of t-PA is superior to the longer (180 minutes) infusion when the dose is equal, in consideration of the faster improvement in cardiopulmonary impairment from pulmonary embolism.

Sirtuin inhibitors are pharmaceutically and therapeutically valuable compounds that inhibit sirtuin, a type III histone deacetylase. Synthetic sirtuin inhibitors were discovered and characterized using cell-based screens in yeast (Saccharomyces cerevisiae) and have been used in the study of aging, carcinogenesis, and diabetes, all of which are related to sirtuin function. For medical applications, synthetic inhibitors have been further developed for increased potency and specificity, including compounds containing nicotinamide, thioacetyl lysine, β-naphthol, and indole derivatives. Suramin, tenovin, and their analogues were developed as a result. Sirtuin inhibitors were found to affect organic development and have been used to genetically modify plants, although a sirtinol-resistant mutation in the biosynthesis of a molybdopterin cofactor for an aldehyde oxidase has been identified. Some natural flavonoids, and catechin and quercetin derivatives also act as sirtuin inhibitors have been studied to identify a more potent inhibitor for therapeutic purposes. In this review, sirtuin is introduced and the therapeutic inhibitors that have been developed are presented, particularly sirtinol which has been used for genetic modification in plants though it was not designed to be so. Sirtuin inhibitors with greater potency and selectivity are required and those developed in pharmaceutics should be used in plant research to identify more authentic sirtuins in plants.

In Korea, the word, 'Literary Therapy' can be replaced by 'Bibliotherapy', 'Journal Therapy', 'Writing Therapy', 'Poem Therapy', 'Integrated Literary Therapy', or 'Imaginary-Oriented Poetry Therapy', and so on. This study, intended on people related to literary therapy, uses Q-methodology as useful research method of objectifying abstract concepts which can be perceived differently according to individual experience or perception, to investigate types of literary therapy's subjective perceptions. The result of study can be analyzed by four types: The first type is 'Pursuing Generalization', the second type is 'Considering the Therapist', the third type is 'Emphasizing the Integration', and the forth type is 'Maximizing the literary therapy'. Through this result of the study, we can find the responsibility of literary therapy as a leader of cultural, artistic therapy to break down various pathological situations which contemporary society have.
