BACKGROUND: The aim of this study is to define the cardioprotective effects (functional and metabolic) of newly developed DelNido cardioplegic solution (containing plasma solution, mannitol, magnesium and lidocaine). MATERIAL AND METHOD: This study assessed the function of rat hearts after itermittent infusion of DelNido cardioplegia with different preserving methods(Air or Icebox) for 2hours and perfusing the hearts on a Langendorff apparatus. Heart rate, left ventricular developed pressure (LVDP) and coronary flow, were measured at pre-ischemic, post-reperfusion 15min, 30min and 45min. Coronary flow was standardized to dry heart weight. Each weight was weighted to calculate water content. Creatine kinase-MB isoenzyme release was measured and ultrastructural assessment was done with electron microscopes. DelNido group was better than St, Thomas group and Icebox group was better than Room-air group. CONCLUSION: DelNido cardioplegia have better myocardial protective effects than St. Thomas cardioplegia when they were preserved in the Room-air. But we can not tell the difference between Delnido cardiplegia with Air preserving method and St. Thomas cardioplegia with Icebox.

Hydrofluoric acid(HF) burn is characterized by progressive tissue necrosis and severe pain. A 31 year old employee in the semiconductor industry came in contact with the 50% aqueous HF through a pin hole in the thumb of his protective gloves. About 2 hours after exposure, h noted deep, severe burning, excruciating pain and svtelling of right thumb. Thereafter, clark bluish eclematous necrotic patches were visible through the nail plate and on the distal end of right thumb. Pain was not effectively relieved by digital nerve block.

OBJECTIVES: The purposes of this clinical study were 1) to assess 5-year survival rates in 195 patients with locally invasive cervical cancer(stage Ia-IIb) treated by surgery, neoadjuvant chemotherapy+surgery and postoperative radiation in selected cases, 2) to evaluate the prognostic factors affecting the survival rate, and 3) to get helpful information for the better treatment. METHODS: A retrospective analysis was conducted of 195 patients. They were diagnosed and operated on during the period of Jan. 1988 - Dec. 1993 in Dept. of OB/Gyn, Pusan Paik Hospital, Inje Medical School. The 5-year survival rates were estimated using the Kaplan-Meier method, and prognostic factors were assessed using Wilcoxon test. RESULTS: The 5-year survival rates for FIGO stages Ia, Ib, IIa, and IIb were 100, 86.1, 76.9, and 81.1%, respectively. Factors that affect the 5-year survival rates were clinical stage(P=0.0001), cell type(small cell vs other, P=0.0001), depth of invasion(< or = 5 mm vs >5 mm, P=0.0013), tumor size(< or = 3 cm vs >3cm, P=0.0035), and lymph node metastasis(0 vs 1 vs more than 2, P=0.0001). There was no difference in 5-year survival rates between without neoadjuvant chemotherapy group and with neoadjuvant chemotherapy group which had poor prognostic factors. The predicted recurrence rate of the postoperative radiation group showed a lower 5-year survival rate than the no postoperative radiation group(P=0.0001). CONCLUSIONS: We conclude that the factors affecting the prognosis were FIGO stage, cell type, depth of invasion, tumor size, and lymph node metastasis, and speculated that the survival rates could be improved by using neoadjuvant chemotherapy for more advanced locally invasive cases properly.

PURPOSE: The purpose of this research was to describe the decision making of nurses in a VIP ward. METHOD: The methodology of collecting and analyzing the data was based on the grounded theory of Strauss and Corbin (1998). The data were collected through an in-depth interview, which were audio-taped and transcribed. The data were collected from 10 nurses from July to November 2007. RESULTS: The core category on VIP ward nurses' decision making was named as "adjusting with flexibility and deepened insight." The causal condition was established by 'the patients who wanted to be treated specially.' The contextual conditions included 'caring patients from various departments,' 'differences depending on the nurses' clinical experience,' and 'client-centered atmosphere in the VIP ward.' The intervening conditions included 'problem solving styles of nurses', 'attitudes of patients and family members', 'nurse-doctor relationships', and 'accessibility to information.' It was confirmed that nurses changed their action-interaction strategies depending on the intervening conditions, thus resulted in the nurses' role conflict and the need to expand their consciousness. CONCLUSION: The result of this study indicates that nurse's decision making depends on their experiences and the nature of social context in which nursing occurs.

Prediction of acetabular development after reduction in treatment of developmental dysplasia of thc hip (DDH) is earlier, the hetter results because it would help ensure optimal timing of additional procedure if necessary. In this respect, authors reviewed retrospectively the radiographs of the hips of 35 children with DDH who had unilateral involvement and treated hy senior author (S.H.Lee) from the heginning with single successful attempt of reduction. The radiographs which were made at the time of initial diagnosis, one, two year nfter reduction und final follow up were assessed of teardrop figures. The results of treatment were classified as satisfactory group(CE > 10degrees ) and unsatisfactory group(CE < 10degrees) judged hy center-edge angle(CE degrees) at final follow-ups. 1. The teardrop figures were classifiable into 4 distinct groups as i)absent. ii)V-shaped, iii)Ushaped, iv) inverted D-shaped. 2. The teardrop figures in normal sides of hip were all U-shaped. 3. In dislocated but with satisfactory result group(24 cases), absent at 2 cases(8%), U-shaped teardrop was seen at 13 cases(54%), V-shaped in 9 cases(38%), and inverted 2-shaped in 0 case at I year after reduction. 4. In dislocated but with unsatisfactory result group( 11 cases), they were mostly of V-shaped(7 cases, 64%). The rest were of ahsent in 4 cases(36%) . hut none of U-shaped and inverted 2-shaped. In conclusions, teardrop figures appeared as significant predictor of future development of hip joint. Teardrop figure which stay as V-shaped at one year after reduction seems suggestive of insufficient reduction of DDH, therehy calls for early additional procedure.

BACKGROUND: Survival time of patients with multiple myeloma has been reported to be closely related to the cytology of bone marrow smears and the histologic features of bone marrow biopsies. However, there have been many differences in morphological criteria applied by various authors. In this study, we evaluated the prognostic relevance of bone marrow features in patients with multple myeloma by investigation of the cytologic feature and the histologic patterns. MATERIALS AND METHODS: One hundred and seven previously untreated patients with multiple myeloma, admitted to Asan Medical Center, between 1989 and 1997, were studied. Bone marrow aspirations and biopsies were analyzed according to the criteria such as cytologic differentiation, volume of infiltration, pattern of infiltration, degree of hematopoiesis, and presence of fibrosis. RESULTS: 64 cases (59.8%) of 107 patients with multiple myeloma were plasmacytic type and 43 cases (40.2%) were plasmablastic type. Each median survival time was 35.0 months and 18.0 months (P<0.05). The patients with more than 25% of plasmablasts showed shorter median survival time than those with 1ess than 25% (18 months vs 38.9 months, P<0.05). The patients with nodular or packed marrow pattern revealed poorer prognosis than those with interstitial or interstitial/nodular pattern (P<0.05). The patients of plasmablastic type disclosed larger volume of myeloma cell infiltration and more packed marow pattern than those of plasmacytic type. CONCLUSIONS: The cytologic differentiation, the volume of infiltration and the patterns of infiltration were reliable predictors of survival in myeloma patients. Thus, for the prognostic evaluation and therapeutic plans, the descriptions for cytologic differentiation (especially percentage of plasmablasts), volume of infiltration and pattern of infiltration should be included in the bone marrow interpretation of multiple myeloma.
