This study was attempted to identify the difference between body image of the patients with lower limb fracture and that of normal persons, and to examine if supportive group care could offer an apportunity for positive change in body image of the patient with lower limb fracture under the Quasi-experimental design. The subjects for this study were obtained by ta-king convenient sample of soldiers; the experimental group were 44 lower limb fractured patients hospitalized on the orthopedic Surgery unit in S Army General Hospital, while the control group were 44 normal enlisted men serving in the B Army regiment. Supportive group nursing care was given to the lower limb fractured patients who belong to the experimental group. Pre-and post-tests were administered to the experimental and the control group. The instruments to measure body image of the subjects were body Cathexis Scale developed by Scord and Jourard (1953) and Body Meaning Scale dove-loped by the reseacher. The reliability coefficients by Cronhach's u-test were .95 in body Cathexis Scale and .89 in Body Meaning Scale in this study. Data for this study were collected over a period 12 days from the 12th to the 24th of October, 1984 by the questionnaire. Data were analyzed by computer. Frequency, Percentage and x²-test were used to examine general chacteristics of the subjects. t-test was used to analyze the hypotheses. Analysis of variance was used to test difference in body image between groups classified by the general characteristics. Pearson Correlation Coefficient was used to identify the correlation between Body Cathexis Scale and Body Cathexis Scale and Body Meaning Scale. The results of this study were as follows: 1. No significant difference was found between the experimental and the control group on general characteristics of the subjects (p> .05). 2. Hypothesis I:“There will be a difference in body image between patiens with lower limb fracture and normal persons,”was supported(Body Cathexis t=6.91, p<.001, Body Meaning t=5.66, p< .001). 3. Hypothesis Ⅱ;“The will be a difference in body image of patients with lower limb fracture bet-ween after and before, supportive group nursing care was provided,”was supported (Body Cathexis t=5.90, p<.001, Body Meaning t=4.45, p <.001). 4. There was no significant difference in body image between groups classified by the general characteristics (p> .05). 5. The correlation between Body Cathexis Scale and Body Meaning Scale: It was reported that Body Cathexis Scale correlated with Body Meaning Scale in total subjects of the experimental and control group (r=.744, p<.001). That is, there was relatively high correlation between two scales. body Cathexis Scale correlated with Body Meaning Scale in the experimental group(r=.738, p <.001) and in the control group (r=.352, p <.001). That is, there was more than moderate correlation between two scales. In conclusion, it was found that there was a difference in body image between patients with lower limb fracture and normal persons, and supportive group nursing care offered an opportunity for positive change in body image of the patient with lower limb fracture.

Purpose: Preshaped Locking compression plate(LCP) has holes with fixed angle between screw and plate and have advantage firm fixation because it has stability of angular and axial deformity. We evaluated usefulness of LCP after open reduction and internal fixation in distal fibular fracture. Materials and Methods: Between December 2011 and May 2012, 23 patients with fracture of distal fibula were followed up at least 12 months underwent open reduction and internal fixation with LCP. There were 15 males and 8 females with a mean age 39.8(20~69) years. According to Danis-Weber classification, there were 20 cases of type B and 3 cases of type C. There were 13 cases of isolated lateral malleolus fractures, 1 case of bimalleolar fracture, 6 cases of trimalleolar fractures and 3 cases of distal tibia fractures with proximal fibula fracture. Intraoperatively, we assessed whether preshaped LCP fit lateral margin of distal fibula or not and evaluated quality of reduction and postoperative complications. The cases were analyzed by radiological bone union time and clinical results according to the criteria of Meyer Results: Of all cases, complete bone union was achieved and average radiological bone union time was 7.3(6~12) weeks. The clinical results were excellent in 18 cases(78%), good in 5 cases(22%). There were 5 cases of plate with 3 holes, 13 cases of plate with 4 holes, 2 cases of plate with 5 holes, 1 case of plate with 6 holes and 2 cases of plate with 7 holes. The average number of screws at proximal fragement was 2.5 and at distal fragment was 3.5. In 14 cases (60.8 %), we needed re-bending of plate because the distance between plate and lateral cortical margin of distal fibula was more than 5 mm at anteroposterior X-ray after reduction. All cases have anatomical reduction and there were no complications of wound infections. There were no complaint about hardware irritation. Conclusion: At fractures of distal fibula,preshaped LCP had a excellent stability although far cortex was not fixed with screw and bending of plate. And there are less complications of hardware irritation and wound problems. But, Some complement would be needed because there were no complete fitting between precontour of LCP and lateral cortical margin of distal fibula.

Suppose that dental occlusion is related to body posture. We want to find out that improving occlusal balance may affect vibration and distribution of C.O.P. in which way, by measuring change of posture and center of gravity (center of pressure, C.O.P.) which plays important role in measuring balance sensation. Total 11 students at Kyung Hee dental college students, 4 females and 9 males (age: 23-30) participated in this test, who have normal occlusion (Angle's classification I), no TMJ problems. All of the participants have no tooth loss except 3rd molar, no prosthesis over single tooth restoration, no orthopedic problems which affect balance sensation, and no otorhinolaryngological problems. First, we registrated bite by centric relation, and then fabricated stabilization splint that is increased 3.5mm vertical dimension around premolar region. By F-scan (Tekscan Inc., Boston, Mass), we measured discrepancy of average contact pressure of left and right foot. And we also measured discrepancy of vibration of C.O.P(center of pressure). before setting stabilization splint and after wearing stabilization splint at intervals of 1 week, 2 weeks, 3 weeks after. In normal human beings, improved occlusal balance by stabilization splint leads to decrease of vibration of C.O.P. (P<0.05). One week after wearing stabilization splint, vibration of C.O.P. decreased reliably (P<0.05), two weeks after wearing stabilization splint, vibration of C.O.P. decreased similarly comparing to before wearing and one week after wearing. (P<0.05) After two weeks and three weeks, however, it was hard to find reliability. (P>0.05) Difference between average contact pressure of right and left foot also decreased. (P<0.05) We could find decrease after one week of wearing stabilization splint (P<0.05) and two weeks after, the decrease was more reliable than one week after. (P<0.05) After two weeks and three weeks, however, it was hard to find reliability. Improvement of occlusal balance leads to decrease of vibration of C.O.P. and decrease of difference between right and left average contact pressure.

연구배경 : 원발성 폐암의 전이 병소 발견은 병변 자체와 위험한 합병증을 예방하기 위한 치료 계획의 수립에 중요하다. 원발성 폐암은 임파절, 부신, 뇌, 간장, 뼈로 잘 전이되며 뼈중에서는 주로 두개골, 척추, 늑골 그리고 장골 등을 침범한다. 편평상피암에서의 골전이는 다른 폐암에 비하여 비교적 낮은 빈도로 알려져 있으며 특히 원위부 족지골에의 전이는 매우 드물다. 방법 : 저자등은 연세대학교 의과대학 세브란스병원에서 우측 제 5 원위부 족지골에만 전이 병소가 발견된 폐암 1 예를 경험하였다. 결과 : 처음 편평상피암의 진단시에 T4N3MO의 상태였으며 세 번째 항암제 투여시 처음으로 원격 전이가 제 5 원위부 족지골에 국한되어 발견되었다. 단순 골사진과 전신 골 주사검사상 우측 제 5 원위부 족지골의 국소적 이상 소견이 관찰되었으며 제 5 족지의 절단 조직검사에서 폐의 편평상피암이 전이된 병변임을 병리조직학적으로 확인할 수 있었다. 결론 : 본 증례의 특징은 뼈중에서도 통상적으로 전이가 잘되는 두개골, 철추, 늑골이나 장골이외에 제 5 원위부 족지골에 처음 전이가 된 것이다. 따라서 원발성 폐암 환자에서 이학적 검사상 국소적인 염증같은 이상 소견이 발견되면 가능성은 비록 적더라도 전이성 병변을 의심해 보는 것이 필요하리라고 생각된다.

Background: Anterior cruciate ligament reconstruction (ACLR) causes a reduction in the balance of the lower extremities. Static and dynamic balance were evaluated separately to confirm the decrease in balance in patients underwent ACLR. The commonly used methods include the Biodex Balance System (BBS) for static balance and the Y balance test (YBT) for dynamic balance. No study has evaluated whether the static and dynamic balance of the involved side recovers as much as the uninvolved side one year after ACLR. Objects: The purpose of this study was to investigate the recovery of static and dynamic balance between the involved and the uninvolved sides. Methods: The BBS (overall, anteroposterior index, and mediolateral index) and YBT (anterior, posterolateral, and posteromedial) of 58 patients underwent ACLR were measured one year postoperation. Both sides of the BBS and the YBT were compared using the paired t-test. Results: All the index of the BBS showed no difference between the involved and the uninvolved sides, while all the scores of the YBT showed a significant difference in both sides. The YBT anterior result was 54.64 ± 5.62 cm in the involved side and 56.90 ± 5.41 cm in the uninvolved side (p = 0.001). The YBT posterolateral results were 90.12 ± 10.51 cm and 92.34 ± 9.85 cm (p = 0.013). The YBT posteromedial results were 93.72 ± 8.84 cm and 96.14 ± 9.37 cm (p = 0.002). Conclusion: A year after ACLR, the static balance showed no difference, while the dynamic balance showed a significant difference in the involved and the uninvolved sides. The static balance of the involved side recovered as much as the uninvolved side, but the dynamic balance did not. Therefore, dynamic balance training should be considered in the rehabilitation program for patients underwent ACLR.

Purpose: The purpose of this study was to identify differences of BMI, pain, depression, self-esteem and self-efficacy between rheumatoid arthritis and osteoarthritis patients. Method: The study subjects were 135 persons having chronic arthritis at rheumatology clinic and the department of orthopedic surgery of the C university hospital in D city. The data were collected from February 19th to April 7th, 2003. The data analysis consisted of $X^{2}-test$, t-test, Pearson Correlation Coefficient, and multiple regression using SPSSWIN 10.0 program. Result: 1. There were significant differences in age(p=0.000), occupation(p=0.015), marriage(p=0.028), duration of illness(p=0.000), BMI(p=0.006) and Self-efficacy(p=0.017) between rheumatoid arthritis and osteoarthritis patients. 2. In rheumatoid arthritis, the BMI and self-esteem(r=-0.239, p=0.05) were significantly correlated and also pain and self-esteem(r=-0.402, p=0.01), pain and self-efficacy(r=-0.455, p=0.01) were significantly negatively correlated. The self-esteem and depression(r=-0.622, p=0.01), self-efficacy and depression(r=-0.729, p=0.01) were significantly negatively correlated and also pain and depression(r=0.432, p=0.01), self-esteem and self-efficacy(r=-0.476, p=0.01) were significantly positively correlated. In osteoarthritis, the pain and self-esteem(r=-0.225, p=0.01) were significantly negatively correlated and also pain and self-efficacy(r=-0.493, p=0.01), self-esteem and depression(r=-0.692, p=0.01), self-efficacy and depression(r=-0.566, p=0.01) were significantly negatively correlated. The pain and depression(r=0.290, p=0.05), self-esteem and self-efficacy(r=0.383, p=0.01) were significantly positively correlated. 3. The factors influenced by the self-efficacy, the depression and age in rheumatoid arthritis explained 56.2%, the depression and pain in osteoarthritis explained 43.9%. The factors influenced by the BMI, the self-esteem in rheumatoid arthritis explained 5.7%, but there was no significantly variable in osteoarthritis. Conclusion: The results support the importance of different nursing intervention focused on BMI and self-efficacy in patients with rheumatoid arthritis and osteoarthritis. There is a need for further studies to identify relation of variables in different diseases related to arthritis.

Objectives : Betula Platyphylla(BP) is a traditional analgesic, anti-fungal, anti-inflammatory herb used in Chinese 1medicine. However, no information is available to explain its action. In this study. we investigated the anti-inflammatory 1effects of BP to elutidate the molecular pharmacological activity in the ethanol extract of BP(BPE). Methods : We performed WTS assay in lipopolysaccharide (LPS) stimulated RAW264.7 macrophages with BPE. Nitrite was measured by Griess assay, prostaglandin E2 (PGE2) by enzyme-linked immunosorbent assay (ELISA) in LPS induced RAW264.7 macrophages with BPE. Inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) were determined by Western blot. Activation of nuclear factor-kappaB (NF-kB) was measured by electrophoretic mobility shift assay (EMSA). Results : BPE significantly suppressed production of nitric oxide (NO) and PGE2 in LPS-induced RAW264.7 macrophages in a dose-dependent manner. The maximal inhibition rate of NO and PGE2 production by BPE was ca. 88.8% and 93% at the concentration of $100{\mu}g/ml$ (non-cytotoxic concentration), respectively. BPE also decreased iNOS protein and COX-2 protein in LPS-induced RAW264.7 macrophages. EMSA demonstrated that BPE inhibited the DNA binding activity of the NF-kB. Conclusions : These results suggest that BPE inhibits NF-${\kappa}B$-mediated gene expression and downregulates inflammatory mediator production in RAW264.7 macrophages.
