PURPOSE: The purpose of this study was to identify predictors of depression and quality of life among older adults with osteoarthritis. The predictors included in the model were the client's characteristics(age, pain, disease duration, ADLs), personal resources(hardiness, self-care agency and family support), and depression. METHOD: 150 subjects who were older than 65 years and had diagnosis of osteoarthritis participated in the study. To answer the research questions, descriptive analysis, Pearson correlation, and hierarchical multiple regression were utilized using SPSS WIN program. RESULT: Older adults who were younger and had lower levels of pain and dependency on ADLs, and higher levels of self care agency and hardiness reported lower levels of depression(R2=0.517). Older adults who had lower levels of depression, pain, and dependency on ADLs, higher levels of family support and hardiness, and who are younger reported higher levels of quality of life(R2=0.804). CONCLUSION: Based on the findings of this study, development of nursing intervention program including pain reduction, enhancing ADL abilities and personal resources (hardiness, family support) can be suggested. Further study is needed to increase the ability of generalization of the study findings to the broader population.

Elevated plasma homocysteine is an independent risk factor for the development of cardiovascular disease. Exercise is generally believed to reduce the plasma homocysteine levels and therefore, being beneficial for cardiovascular disease(CVD). However, there is a possibility that athletes undergoing strenuous training and competition which increase oxidative stress may suffer from increased plasma homocysteine levels. The purpose of this study was to investigate the influence of endurance training on the plasma concentrations of B vitamins and homocysteine in 23 male adolescent field hockey players. Data collection and blood sampling was performed during the training period and non-training period. Following the training period, significant changes in energy and vitamin B6 intakes were observed in these subjects. Plasma vitamin B2, pyridoxal phosphate (PLP) and homocysteine levels were significantly higher during the training period than non-training period, whereas no difference was observed in plasma folate and vitamin B12 levels. Positive correlation was observed between plasma folate and folic acid intakes. When energy, B vitamin intakes were adjusted there was a significant negative correlation between plasma homocysteine levels and plasma riboflavin, folate and vitamin B12 levels. In conclusion, it is suggested that athletes with oxidative stress by strenuous exercise may need B vitamins since riboflavin, folic acid and vitamin B12 were shown to be negatively correlated with plasma homocysteine in athletes during the training period.

An attempt has been made to discriminate synaptic diversity in the neostriatum of the cat with emphasis on the characteristic structures of axon terminals and postsynaptic profiles. The differentiation of the axon terminals was based on the size and shape of synaptic vesicles in the axoplasm. Three types of axon terminals could be differentiated: Type I, the terminals contained small round (45 nm in diameter) vesicles; type II, the terminals with large pleomorphic (50 nm) vesicles; and type III, the terminals contained flattened (45 x 25 nm) vesicles. The type I terminals were making asymmetrical or symmetrical synapses in contact with the somata, dendrites and dendritic spines of neurons in the neostriatum, and a few type I terminals making asymmetrical or symmetrical contact with axons were also observed. The type II and III terminals were making symmetrical contact with the somata and dendrites of neostriatal neurons. A few type II terminals formed at the node of Ranvier of myelinated nerve fibers were making symmetrical contact with large dendrites. Additionally, dendro-dendritic and serial syanpses were rarely found in the neostriatum. In the serial synapses composed of axo-dendritic and dendro-dendritic synapses, the type I terminals making asymmetrical contact and the type II making symmetrical contact were identified.

PURPOSE: Laparoscopic management of intestinal obstruction is hypothetically attractive, However little is known about this procedure in our country. With new advances in diagnostic and therapeutic tools such as laparoscopic procedures, the management of intestinal obstruction has become feasible. METHODS: In order to analyze the clinical results of laparoscopic adhesiolysis, a retrospective review of a consecutive series of 20 cases of intestinal obstruction unresponsive to medical management was done between 1997 and 2000. RESULTS: The mean surgical time for the laparoscopic procedure was 75 min and two cases were converted to open surgery due to dense adhesion and intestinal strangulation. The characterization of adhesion type included 10 cases with simple fibrotic band, 4 cases with multiple fibrotic band and 5 cases with dense adhesion. Additionally, the most common site for adhesion was the small intestine and colon (12 cases). The mean diet start time was 2.3 days, mean hospital stay was 4.7 days and totally mean analgesic use was 1.6 times. CONCLUSION: Laparoscopic management of adhesive bowel obstruction is feasible and safe in experienced hands. The laparoscopic procedure also is an excellent diagnostic modality in case of obstruction, and the majority of these cases can be simultaneously managed laparoscopically. A laparoscopic approach is recommend as a first choice of treatment for selective cases of intestinal adhesion.

PURPOSE: The purpose of this study was to identify the current attitudes and knowledge toward Koryo Hand Therapy(KHT) by the experienced people. METHOD: The Subjects for this study included 3,351 people living in Korea who experienced KHT. The data were collected from April 6 to November 25, 2004 using a structured questionnaire. The data were analyzed through the SAS 8.1 Windows Program using frequency, percentage, t-test, ANOVA and Pearson's correlation coefficient. RESULTS: The results of the study are as follows: 1) Families and relatives were a main source of information about Koryo Hand Therapy. The subjects were very satisfied with therapeutic and preventive effects of the therapy. Sujichim was the most preferable choice in the KHT. Most of the subjects thought that KHT could be applied to modern medicine. 2) Those who experienced KHT had a high level of knowledge and very positive attitudes toward KHT. 3) There were statistically significant differences in the attitude toward KHT according to age, gender, educational level, religion, income, place of residence, marital status and experience which studied KHT. 4) There were significant differences in the knowledge of KHT according to age, educational level, income, marital status and experience which studied KHT. 5) The data showed positive correlation between attitude and knowledge. CONCLUSION: According to the above findings, it can be concluded that KHT needs to be actively informed and more easily approached by general peoples. Nursing protocols of KHT needed to be developed.

PURPOSE: To evaluate the clinical significance of the multiple increased uptake lesions other than in femoral heads as seen on whole body bone scan in patients with avascular necrosis of femoral heads. MATERIALS AND METHODS: One hundred and seventy three patients with clinical diagnosis of avascular necrosis of fthe emoral head underwent a bone scan using Tc-99m MDP. Increased uptake lesions other than in femoral heads were evaluated, including frequency and common sites of involvement, and correlated with clinical information and plain radiographic findings. Two hundred patients without AVN, who had undergone a bone scan, were included as a control group. RESULTS: Increased uptake lesions in extrafemoral head locations were found in 36 of 173 patients(20.8% ; the location of 79 lesions was other than the femoral head, This result is statistically different from patients without avascular necrosis of femoral head(p<0.0001). The most common site of involvement was the knee joint area(62.5%). Other lesions were located in the mid-shafts of the long bones of the lower extremities, calcaneus, proximal humerus, etc., in order of decreasing frequency. Plain radiographs of 17 lesions were nonspecific, except for three lesions showing definite changes associated with avascular necrosis. The risk factors included alcoholism, the prolonged use of steroids, renal transplantation, herbal medication and working as a working as deep-sea diver. Most patients did not complain of pain, except for two with irreversible osteonecrotic changes as seen on plain radiograph. CONCLUSION: in patients with avascular necrosis of the femur, increased uptake lesions other than in the femoral head as seen on bone scan, may represent the early stage of osteonecrosis, which shows a characteristic appearance on bone scan. In order to avoid possible misdiagnoses of multiple extrafemoral lesions as bony metastasis or traumatic lesions, in patients with avascular necrosis of the femur these should be carefully evaluated.

In our study we estimated mitral orifice area by use of two dimensional echocardiography in 59 patients with mitral stenosis form February 1979 till June 1981. We classified them to 3 subgroups by severity of mitral stenosis as Cope was done in 1975. and investigated correlationship between the severity and other various echo-cardiographic findings indices such as mitral valve calcification, posterior mitral leaflet motion, doming of mitral valve, EF slope, ED amplitude, LA dimension, LA/Ao ratio and especially mitral valve closure index. The following results were obtained. 1) We could accurately estimate mitral orifice area by two dimensional echocardiography. 2) Except EF slope and MVCI, we could find that various echocardiographic findings were poorly correlated with mitral orifice area measured from two-dimensional echocardiography. 3) MVCI was overlapped less frequently than EF slope in severe, moderate and mild mitral stenosis, and we could find that MVCI reflected the extent of mitral stenosis more accurately than EF slope.
