Background : The survival benefit associated with first-line chemotherapy in lung cancer has led to the need for second -line chemotherapy, for which Docetaxel (Taxotere^(?)) has proven efficacy in both settings. This study evaluated the safety and efficacy of docetaxel in patients with non-small cell lung cancer who had failed first-line platinum-based chemotherapy. Methods : Thirty one patients with non-small-cell lung cancer, who had failed first line platinum-based chemotherapy, between March 1999 and August 2003, were enrolled in this study. Patients received intravenous docetaxel, either 75 mg/㎡ or 100 mg/㎡, with routine premedication every three weeks. Results : Fourteen patients (45.2%) had a partial response. The median survival and progression- free survival times were 12.5 months (95% CI 7.3-17.6) and 3.0 months (95% CI 1.6-4.5), respectively. This study showed 2 factors gave different survival benefits; the age (< 60 years: 20.1 months vs. > 60 years: 6.6 months, p=0.0105) and the histological type (adenocarcinoma: 25.6 months vs. others: 7.9 months, p=0.0055). The predominant toxicity was neutropenia, which occurred as WHO grade 3 or 4 in 38.7 % of patients. One treatment related death was also reported. Non-hematological toxicity was minor and easily controlled. There were no significant statistical differences in the survival benefit and toxicity between the two doses. Conclusion : Docetaxel, as second-line monotherapy, was well tolerated and effective in patients with non-small-cell lung cancer who failed first line platinum -based chemotherapy.

Background : Both gemcitabine and vinorelbine are effective anticancer drugs with mild toxicity on non-small cell lung cancer, and monotherapy of these drugs are effective as a second-line chemotherapy. The aim of this trial was to assess the response and toxicity of a combination of gemcitabine and vinorelbine in patients of previously treated for non-small cell lung cancer. Materials and Methods : 24 patients, initial stage III A/B,IV and previously treated with platinium and taxane based regimens, were enrolled from June 2000 to March 2004. The regimens consisted of vinorelbine 25mg/㎡ followed by an infusion of gemcitabine 1000mg/㎡ on day 1 and day 8 every three weeks. This course was repeated more than twice. Results : Twenty-four patients were analyzed for the response, survival rate, and toxicities. The overall response was 17% with a complete remission rate of 4%. The median time-to progression (TTP) was 3.1 months (95%, CI l-10months), and the survival time was 8.2 months (95%, CI 1-23 months). The grade 3/4 toxicities encountered were neutropenia (12.5%), anemia (0%), thrombocytopenia (0%). Non-hematological 3/4 toxicities were not observed. Conclusion : A combination of gemcitabine and vinorelbine in patients previously treated for non-small cell lung cancer provides a relatively good response rate, and a low toxicity profile. However, further study will be needed to confirm its effectiveness. (Tuberc Respir Dis 2005; 58: 344-351)

Heat stroke is a life-threatening illness characterized by an elevated core body temperature that rises above 40% and central nervous system dysfunctions that results in delirium, convulsions, or coma. Heat stroke is subdivided into two forms, classic and exertional. Since strenuous exercise is one of the major exacerbating and precipitating factors, the incidence of exertional heat stroke is high among young adult, especially military personnel undergoing military training. Exertional heat stroke commonly causes rhabdomyolysis, lactic acidosis, acute renal failure, shock and pulmonary edema. We report a case of heat stroke with rhabdomyolysis, acute renal failure, disseminated intravascular coagulopathy(DIC) after strenuous exercise. A 18 year old man was admitted to the hospital because of loss of consciousness. He was a wrestler and he had tried to lose 6kg in weight by jogging and strenuous exercise on that summer day with hot temperature. The development of this illness was favoured by much clothes inappropriate for that environmental condition with a purpose to enhance sweating, and by restricted intake of water and food. On admission, the blood pressure was 80/50mmHg, and body temperature was 39.4℃ with stuporous mentality. Laboratory finding were as follows : in complete blood cell count, hemoglobin was 16.7g/dL and platelet count was 158,000/ mm³. In blood chemistry, AST 1061U/L, ALT 201U/L, BUN 30mg/dL, Cr 2.2mg/dL, LDH 941IU/L, CK 696IU/L were resulted. In arterial blood gas analysis, pH 7.39, pCO₂ 30mmHg pO₂ 86mmHg, HCO₃ 18.4mEq/L, O₂ saturation 96.7% were resulted. In urinalysis, specific gravity 1.025, protein 3+, erythrocyte 2+ were resulted. In brain imaging study, brain CT finding was normal. After appropriate treatments with rapid cooling, hydration and supportive care, he improved with alert mental status. On 2nd hospital day, in laboratory result, thrombocytopenia and coagulopathy were appeared and renal insufficiency was aggravated. So he was treated with platelet concentrate and fresh frosen plasma for DIC, and enough hydration for appropriate urine volume preservation. After all, On 22nd hospital day, he fully recovered and discharged. Nowadays, with followed for some duration, he is wellbeing with no complications.

Objective : The Angelica gigas Nakai ethanol extract (AGE) was investigated to compare nitric oxide (NO) production and NF-kB activity from RAW 264.7 cells, since NO and nuclear factor-kB(NF-kB) have been shown to be factors implicated In inflammatory disease. Method : AGE was prepared by extracting medicinal herb with 70% (v/v) ethanol solution. We investigated production nitric oxide (NO) and inducible nitric oxide synthase (iNOS) gene expression by ARE in LPS-stimulated RAW 264.7 macrophage cells. We also investigated inhibition of LPS-induced activation of NF-kB on western blot. Result : LPS-induced RAW 264.7 cells increascd NO production and ,iNOS expression. Upon treatment with AGE, nitrite production was significantly inhibited in a concentration-dependent manner compared to the untreated control. AGE inhibited this LPS-induced ,iNOS mRNA and protein in a dose-dependent manner. AGE markedly inhibited the expression of iNOS mRNA and protein at a concentration of 100 μg/ml. LPS-induced RAW 264.7 cells with AGE blocked inhibitory factor-kBα degradation. Conclusion : This study shows that AGE seems to attenuate inflammation through inhibition of NO production and iNOS expression by blockade of NF-kB activation in LPS-stimulated RAW 264.7 cells.

The purpose of this study was to analyze training needs and current situation of career development of office workers in small-medium sized enterprises and large corporations to find initiatives for supporting career development in Korea. The survey was conducted to HR practitioners in small-medium sized enterprises and large corporations about training situation of office workers, competency level of office workers, areas in need of training, and needs of curriculum development from government subsidized programs. Findings from this study was as follows. First, most of the companies prefer workers with job professional competencies. Second, expert level job competency was required for office workers as they got promoted. Third, 74.9% of responding companies was conducting job training and average training hours per year for workers were 49 hours. Forth, 64.8% of responding companies was conducting outsourcing training. Especially for small and medium sized companies, they tended to more rely on outsourcing training. Fifth, only 25.7% of responding companies was conducting succession plan. Sixth, 69.7% of responding companies reacted positively about developing government-directed training program. Finally, if the Korean government develops training curriculum for office workers, 58.5% of the responding companies answered that they would have their employees take the training programs. In short, ① Needs of strategic approach for strengthening general competencies and professional competencies for office workers, ② Request of supporting policy for strengthening job competencies of office workers focusing on small and medium sized enterprises, ③ Neccessity of introduction and operation of career development system, ④ Operating task analysis, job analysis, environment analysis in the field of HR, Labor, Marketing, Accounting which needs to be developed in advance by the Korean government were suggested.
