Some variables can influence the efficiency of leukocyte removal filter for red cell concentrates. We performed this study to evaluate whether the filtration efficiency for platelet concentrates(PCs) can be influenced by bedside filter(PXL8K, Pall Corporation, USA) used, platelet storage time and transient stopping of platelet agitation, and to measure the amount of cytokines released from donor leukocytes in PCs during the storage time. In addition, we examined the effect of leukocyte reduction by filtration before the storage of PCs on the subsequent generation of cytokines. Any of the above mentioned variables did not make significant differences. From day 1 to day 5, there were significant increases in IL-1 beta (<1 vs. 8.6 pg/mL, p<0.05), IL-8 (<10 vs. 455.3 pg/mL, p<0.05) and TNF-alpha (<4 vs. 16.6 pg/mL, p<0.05) in unflltered PCs, whereas no increased revels of cytokines were found in the cases of prestorage filtration.

To investigate the influence of first six-month mean for serum biochemical markers, albumin, cholesterol, triglyceride, inorganic phosphate, BUN, creatinine, on survival in hemodialysis, we retrospectively analyzed the 57 patients who were monitored from the start of HD for more than 6 months between January 1988 and December 1995. Exclusion criteria were as follows: transfer to CAPD, transplantation or another dialysis center, HD for less than 6 months, non-compliant, death due to malignant disease, accident and self-withdrawal. The patients were divided into two groups according to the demographic characteristics and the median value of first six-month mean for serum biochemical markers. The mean age was 46.7+/-11.7 year, male-to female ratio was 1.6:1, diabetics were 12 (21.1%), and mean follow-up duration was 39.0+/-26.4 months. Among them 30 patients (52.6%) were died. Diabetic patients had significantly lower 1 year (63.6 vs. 88.8%, p<0.05) and 3 year survival rate (19.1 vs. 62.2%, p<0.05) than non-diabetic patients. Low serum albumin(<3.5g/dl), low serum cholesterol(<130mg/dl) and low serum P (<5.0mg/dl) groups were significantly lower 1 and 3 year survival rate than high serum albumin (63.6 vs. 97.0%; 25.5 vs. 74.6%, p<0.05), cholesterol (71.4 vs. 88.0%; 38.1 vs. 60.8%, p<0.05) and p (71.9 vs. 96.3% ; 47.1 vs. 62.9%, p<0.05) groups, respectively. There were no differences in survival rate according to sex, BUN, TG, and creatinine. By Cox's proportional hazard model, low serum albumin(odds ratio 1.98), cholesterol(odds ratio 1.60), and P(odds ratio 2.09) group were independent risk factors for early death. Low serum albumin level at the start of HD maintained during the follow-up period. Cholesterol and P showed similar results. In conclusion, basal serum biochemical markers associated with visceral protein depletion such as low serum albumin, cholesterol and P seem to be early predictors of mortality in hemodialysis patients.

Imatinib mesylate is a selective Bcr/Abl kinase inhibitor and an effective anticancer agent for Bcr/Abl-positive chronic myelogenous leukemia. Most patients in chronic phase maintain durable responses; however, many in blast crisis fail to respond, or relapse quickly. Mutations within the BCR/ABL kinase domain are the most commonly identified mechanism associated with relapse. To overcome the imatinib resistance in CML, many investigators have tried to clarify molecular mechanism for imatinib resistance in cells of patients who failed to respond to imatinib. Our aim was to invesitigate underlying mechanism for imatinib resistance in SR-1 cells, which were derived from a CML patient in blast crisis. We detected the new mutation of BCR/ABL, resulting in premature termination and loss of BCR/ABL fusion protein expression, which might be possible mechanism for the resistance to imatinib in SR-1 cells.

PURPOSE: With the changes to the medical environment and to the educational system, we aim to evaluate the current mission statement of the College of Medicine, Ewha Womans University, and revise it. METHODS: To establish the new mission statement, a special committee, the School Mission Revision Committee(SMRC) and an advisory group were organized in 2003. The SMRC functioned through 4 stages of action composed of: investigation, draft development, surveillance of various opinions, and announcement. RESULTS: The revised, final mission statement was: "To contribute to Korea and to the international society by producing excellent woman-leaders in healthcare, who have professional medical knowledge and are humanitarians based on Christian principles." Three key words helped in the realization of this mission: compassion, professionalism, and service. Compassion: a noble physician who practices compassion toward mankind, caring for patients with compassion and the right attitude, and contributing to health promotion. Professionalism: a responsible physician who embodies professionalism, learning the necessary knowledge and skills, having the ability for self-development, and leading in various fields of medicine. Service: a respected physician who serves society, devoting to the community with excellent woman leadership skills and an open mind, and serving Korea and the international society. CONCLUSION: We expect that this new school mission will be helpful in clarifying the whole educational process and will resolve conflicts resulting from the change to the school system within a rapidly changing educational environment.
