BACKGROUND: It has been suggested that diabetic patients are under high oxidative stress and plasma MDA concentration is a reliable marker for oxidative stress. However, some studies showed that plasma MDA is not a good marker for oxidative stress. Reeently, the total radical-trapping antioxidant parameter (TRAPc) has been proposed as a marker for the overall antioxidant property of plasma samples. Therefore, in this study, we tried to evaluate whether MDA and TRAPc are reliable markers of the oxidative stress-antioxidant system or not. METHODS: The plasma samples from 67 type 2 diabetic patients and 31 normal subjects were collected. The plasma MDA, protein-bound SH groups, uric acid and vitamin C were determined by fluorophotometry or spectrophotometry. Plasma vitamin E concentration was analyzed by HPLC. Calculated TRAP (TRAPc) were determined by the proposed calculation methods. RESULTS: 1. Diabetic patients had significantly lower TRAPc, compared with normal subjects. 2. SH groups, uric acid, vitamin C and vitamin E were not different between the two groups. 3. MDA and MDA/TG were significantly higher in diabetic subjects. CONCLUSION: From the results of this study, TRAPc seems to be a reliable parameter of overall plasma antioxidant system and the plasma MDA may be used as a marker of oxidative stress, but further long-term logitudinal studies are needed.

Cutaneous metastasis from the tumors of internal organs is rare, but often gives a clue to diagnosis. Metastasis to the abdominal skin including umbilicus has frequently originated from a tumor of the large bowel, ovary, stomach and pancreas. We report two cases of metastatic adenocarcinoma developed on the abdominal wall. One at the umbilicus clarified the origin as a pancreatic carcinoma, and the other at the sites of previous laparascopy and paracenthesis was originated from an ovarian cancer.

Recently, we experienced a patient with a B cell leukemia which could not be classified as chronic lymphocytic leukemia (CLL), prolymphocytic leukemia (PL) or follicular lymphoma in leukemic phase. He is a 58-year-old male and suffered from progressive lymphadenopathy at both inguinal and cervical areas. His blood film showed lymphocytosis (79%), and the cells were heterogeneous in size and shape. Twenty-five percent of the lymphocytes had nuclear irregularities or cleavages unlike the lymphocytes of CLL In which the cells often shows monomorphic features, small size with scanty cytoplasm and round nucleus. The bone marrow trephine biopsy specimen showed a diffuse pattern of infiltration of atypical Iymphoid cells. The lymph node histology showed atypical lymphoid colls proliferated as wide mantles around non-neoplastic appearing germinal centers. The immunophenotype of circulating lymphocytes in peripheral blood showed strong reactivity with CD5, CDl9 and CD20 without expression of CD2, CD3, CD7, CD10, CD22 and CD23. Although this case resembled CLL, the laboratory features showed major differences, notably in the Peripheral blood morphology, histology Patterns and the membrane Phenotype. By combining these data, we diagnosed this case as a leukemic phase of mantle cell lymphoma.

BACKGROUND: Paramedian approach is more useful than midline approach when degenerative changes are encountered in the interspinous structure and when ideal positioning of the patient can not be achieved. The purpose of this study was to determine the guideline of depth from skin to subarachnoid space by midline or paramedian approach in Korean adult. METHODS: The distance from skin to subarachnoid space was measured in 47 patients recieving spinal anesthesia by midline approach and 30 patients by paramedian approach at L3-4 level. RESULTS: The mean depth to subarachnoid space was 5.44+/-0.47 cm in midline approach. In paramedian approach by 18.0degrees of caudal and 18.5degrees of lateral angle, mean depth was 6.24+/-0.60 cm. There were significant correlation between depth and weight, and depth and ponderal index. In ages over 50 years old, difficult cases were significantly more in midline approach than in paramedian approach. CONCLUSIONS: Measurement of factors as weight or ponderal index can be used to predict the depth. Paramedian approach is more useful than midline approach in ages over 50 years old.

OBJECTIVE: The aim of this study was to develop a decision support system that helps school nurses manage health problems they encounter while caring for the elementary and secondary school students, and evaluate usability of it. METHODS: Knowledge was aquired by literatures review and interviews with senior school nurses and was validated by another group of school nurses. The Omaha System was used as a standardized nursing terminology to describe nursing diagnoses and interventions. The system was developed under the Windows environment. C++ was used as a program language and MS Structured Query Language as a database. To investigate usability of the system, 30 school nurses in elementary and secondary schools were recruited and asked to apply it to nursing problems they encountered in actual students care setting. RESULTS: The decision support system with seven major signs and symptoms was developed. It automatically makes a nursing diagnosis based on the input data, and also provides nursing interventions with evidence. It was proven that the system was very useful for school nurses to manage students` health problems. CONCLUSION: The system will contribute to development of expert knowledge concerning student's health problems and improve the quality of school nursing and professionalism.

This study was undertaken to compare the effects of furosemide on the serum concentration of sodium and osmolality after transurethral prostatic resection(TURP) using cytal solution, and to determine the adequate time of administration of frurosemide. At the end of prostatic resection, 15 patients were allocated randomly to receive furosemide (furosemide group) and were compared with 15 patients without administration of furosemide (control group). There was no difference in mean serum concentation of sodium between two groups. Serum osmolality in furosemide group was significantly increased as compared with control group one hour after operation. So cytal solution used during staged TURP and short operation within one hour do not affect serum corcentration of sodium and administration of furosemide is not associated with a change in serum concentration of sodium. But furosemide meaningfully increases the serum osmolality and it is more effective to administer it with administration at the end of prostatic reseetion.

The purpose of this study was to investigate the influence of hypothermia on the recovery time after either vecuronium or atracurium given by repeated bolus injection, and to determine the adequate time of administration of neuromuscular blockers during cardiopulmonary bypass. Two groups of 10 patients each were studied before(Tl), during(T2) and after(T3) hypothermia. Following an initial intravenous bolus dose of 2X ED95 of either vecuronium(Group I) or atracurium(Group II), repeated bolus dose of ED95 was injected whenever twitch tension had returned to 20% block of train-of-four response before bypass of control As a result, the action duration of vecuronium(from injection of loading dose to twitch tension=20%) was 29.5+/-5.5 mins, 103.1+/-12.0 mins and 70.8+/-9.9 mins before, during and after hypothermia, respectively. The eorresponding values for atracurium were 26.3+/-5.1 mins, 85.7+/-11.4 mins and 42.5+/-5.1 mins. We conclude that hypothermia increases significantly the duration of action of both muscle relaxants(P<0.001) and vecuronium is influenced by hypothermia more than atracurium. The rate of recovery of twitch height after hypothermia is more rapid in atracurium than vecuronium(P<0.001). Single bolus injection of ED95 of vecuronium administered just before cardiopulmonary bypass is suitable for maintaining the neuromuscular block throughout cardiopulmonary bypass.

PURPOSE: The purpose of this study was to evaluate the effects of clinical practice and simulation-based practice for obstetrical nursing in terms of self-efficacy, practice satisfaction, and practice stress. METHODS: A non-equivalent control group post test design was used. The participants were 171 junior nursing students, 103 in the experimental group, and 68 in the control group. Simulation-based practice consisted of nursing assessment during labor, nursing assessment and intervention for normal and high risk mother, nursing education for mother and family during labor, and open lab. The experimental group participated in simulation-based practice for two days and the control group participated in clinical practice at delivery room for two weeks. RESULTS: The experimental group showed higher level of self-efficacy (p=.043), practice satisfaction (p<.001) and practice stress (p=.003) compared to the control group. CONCLUSION: Simulation-based practice is an effective learning method for obstetrical nursing and can be used as the alternative for clinical practice. However, stress management strategies are needed for simulation-based practice.
