Purpose: This study was done to apply failure mode & effect analysis (FMEA) to chemotherapy in order to reduce prescribing, dispensing and administering errors related to treatment and provide patients with a safe medical environment. Methods: A one group pre-post test design was used to verify the effects using the tool for FMEA in chemotherapy. Results: There was a statistically significant decrease in prescribing errors from 11.47% to 3.18%; administering errors decreased but they were not statistically significant. In a addition, there was no change in dispensing errors. Conclusion: The results show that FMEA removed risk factors that might occur during the process of chemotherapy and that it was an effective tool for prevention of negligent accident occurring in actual patients.

Objective : 황금의 유방암세포주에 대한 항암효과 및 기전에 대한 연구는 아직 미흡하며, 특히 에스트로젠리셉터를 가지지않은 유방암세포주인 MDA-MB-231에 대한 효과 및 기전에 대한 연구는 아직 발표된바 없어, 이에 대한 연구가 진행되었다. Methods : 인간 유방암세포주 MDA-MB-231 MTT assay를 이용 성장방해비율을 조사하였으며. FACS analysis를 이용 cell cycle analysis를 시행하였고, Western Blot Analysis 및 Annexin V analysis를 시행하였다. Results : MDA-MB-231에 대한 황금의 IC50는 180 ug/ml 이었으며 최대 세포성장억제효과는 $500{\mu}g/ml$로 한약재중 비교적 강한 세포독성을 보여 주었다. 유세포분석 에서 황금 $500{\mu}g/ml$의 농도를 72시간 투여한 경우 세포사멸(Sub Gl) 분율이 대조군의 1.7%에 비해 21%로 높아 현저한 용량의존적인 세포사멸현상을 보여주었으며, 세포사멸을 보다 명확히 규명할 수 있는 Annexin V analysis에서도 황금 $200{\mu}g/ml$농도일때 48시간에서 17%의 뚜렷한 세포사멸효과를 나타내었다. 한편 세포사멸촉진인자인 Bax, 세포사멸실행단백질인자인 caspase 3의 활성과 PARP의 분할은 세포사멸이 세포주기정지와 더불어 세포사멸의 과정에 p53이 관여함을 알 수 있다. 앞으로의 연구는 p53발현이 다른 세포주와 각 단백질의 억제제를 통해 인과적인 관련성을 즘 더 명확히 할 필요가 있어야 할 것으로 생각되어진다. Conclusion : 유방암의 예후에 있어 호르몬치료에 부적절함으로 인해 예후가 나쁜 에스트로젠리셉터 발현이 없는 유방암에 대해서도 황금이 탁월한 항암효과를 보여주고 있으며, 임상적으로 황금단독, 다른 항암약재와의 배합, 그리고 기존의 항암화학요법이나 방사선요법과의 병용투여를 통한 초기 및 진행된 유방암의 치료에 대한 새로운 접근의 실마리를 제공할 것으로 생각된다.

Spontaneous pneumothorax accompanying primary lung cancer is rare and its occurrence as an initial sign of primary lung cancer is much rarer. A few articles on spontaneous pneumothorax accompanying lung cancer have been published in Korea so far. Lung cancers, diagnosed after spontaneous pneumothorax, are usually in advanced stage, so that conservative treatment modalities such as closed tube thoracostomy, chemotherapy, or radiotherapy are the mainstream of the treatment. We experienced a case of local recurrence of primary lung cancer in six months after radical resection and radiotherapy of neoplasm performed immediately after the diagnosis by excisional biopsy of bulla, for which resection and pleurodesis had been done under the impression of spontaneous pneumothorax. In this paper, we report the case and follow-up observation of the patient.

Background and Objectives: Standard treatment of locally advanced laryngeal, hypopharyngeal, and some oropharyngeal cancers includes total laryngectomy. In an attempt to preserve the larynx through induction chemotherapy, we designed induction chemotherapy followed by definitive radiation in patients with potentially respectable head and neck cancer to determine whether organ preservation is feasible without apparent compromise of survival. Materials and Methods: The twenty-six patients diagnosed advanced head and neck squamous cell carcinoma, Stage III or IV (AJCC 2002) and performed organ preservation protocols in Ajou university hospital from 1994 to 2001 were included in this study. Results: Neoadjuvant chemotherapy showed an overall response rate of 84.6% and a complete remission (CR) rate was 59.1% following neoadjuvant chemotherapy and radiation. Seven of thirteen patients were able to preserve their larynges for more than two years by chemotherapy and radiation. There were no treatment related mortality after 2 cycles of induction chemotherapy. Conclusion: Although Organ preservation protocol through neoadjuvant chemotherapy and radiation need more controlled randomized study, it was considered alternative treatment modality in advanced head and neck cancer.

Purpose: The purpose of this study was to examine the effects of cold oral gargling on oral discomfort among Non-Hodgkin's lymphoma patient undergoing chemotherapy. Method: An quasi-experimental, nonequivalent control group design was used. Thirty two patients receiving chemotherapy at G hospital in P city were recruited from August 1, 2002 to October 20, 2002. Sixteen were conveniently allocated into the experimental group and 16 into the control group. Participants in the experimental group used cold oral gargling while their counterparts used room temperature oral gargling. Subjective and objective oral discomforts were measured by the instruments developed by Beck. The SPSS WIN 10.0 program was used to analyze the data with t-test, ${\chi}^2$ -test, and repeated measures ANOVA. Findings: The participants in the experimental group reported less oral discomfort and showed better oral conditions than those in the control group at the post 7th, 14th, and 21st days. Participants in the experimental group reported better oral conditions in taste, tongue, eating, and saliva than those in the control group. Conclusion: The cold oral gargling seemed to be more beneficial than room-temperature oral gargling in reducing oral discomfort for the Non-Hodgkin's lymphoma patients undergoing chemotherapy.

Purpose: This study was conducted to examine utilization of alternative therapies and understand decisional criteria related to use of alternative therapies among chemotherapy patients. Method: Data were collected from 165 cancer patients through the use of questionnaire and interviews at the chemotherapy treatment rooms of two general hospitals located in Seoul. Result: Sixty point six percent of subjects after cancer diagnosis have experience of using alternative therapies and 39.4% were still using alternative therapies. On the average the patients used alternative therapies for 9.4 months and they paid 483,000 Won per month for alternative therapies. Decisional criteria related to use of alternative therapy were curability, social group influence about alternative therapy, confidence in alternative therapy, present symptoms, and who decide on the use of alternative therapy. These variables in the alternative therapy group were statistically different from those of the hospital treatment only group. Conclusion: Utilization rate of alternative therapy among chemotherapy patients is high and cost burden is heavy. Thus, they need to be educated about utilization of alternative therapy by nurse and medical personnel.
