The present study was performed to investigate the role catecholamine in the genesis of reperfusion injury of ischemic heart. The possible involvement of catecholamine in the xanthine oxidase-linked production of oxygen free radicals was studied. langendorff preparations of rat hearts were made ischemic for 60 min followed by reperfusion. Upon reperfusion norepinephrine(NE) was significantly released into the coronary effluent regardless of oxygenation of the perfusion solution. Both the increased releases of creatine phosphokinase(CPK) and malondialdehyde(MDA) and the production of superoxide anion in the ischemic-reperfused hearts were significantly reduced by the treatment with either reserpine, a catecholamine depletor, or propranolol, a beta-adrenergic receptor blocker. In the reserpinized hearts, infusion of exogenous NE reversed the releases of CPK and MDA and the superoxide anion production to the original higher levels. The releases of CPK and MDA as well as the production of superoxide anion induced by NE in the reserpinized hearts were significantly depressed either by allopurinol, a specific competitive inhibior of xanthine oxidase(XOD), or by the calcium removal from the perfusion solution. Compared with the XOD activity of control ischemic hearts, that of the hearts treated with reserpine or propranolol showed lower activity in the oxygen radical producing 0-form and higher activity in D/0-form. In the reserpinized ischemic hearts, infusion of exogenous NE increased 0-form, but decreased D/0-form of XOD. The changes in XOD activities induced by exogenous NE was prevented by phenylmethylsulfonyl fluoride(a serine protease inhibitor) and pimoxide(a calmodulin inhibitor) as well as by calcium removal from the perfusion solution. It is suggested from the results that in the inchemic-reperfused heart of rat catecholamine participates in D/0 to 0-form conversion of XOD by promoting the calcium-calmodulin-dependent proteolysis and plays a contributing role in the production of oxygen free radical.

Journal of Korean Academy of Child Health Nursing 2011;17(3):153-160
PURPOSE: The purpose of this study was to identify differences in sexual knowledge, attitudes and perspectives of sexual values for female students as these factors related to sexual characteristics. METHODS: The participants were 835 girls in junior or high school from Seoul and Kyunggi province in Korea. Data were collected using self-report questionnaires and analyzed using descriptive statistics, t-test, F-test and Scheffe with the SPSS 14.0 WIN program. RESULTS: The major results were as follows: First, for sexual knowledge, there were significant differences for girls from homes with conservative atmosphere and for those who had experiences related to porno. Second, related to sexual attitudes, students who had experience related to porno, were significantly more positive, and had a more open attitudes than students with no experience. Third, for perspectives of sexual value, students who perceived a conservative home atmosphere, who had boy friend, and who had experiences related to porno, had a more positive sexuality, and attitudes towards sexual equality. CONCLUSION: The findings indicate that it is necessary to develop special sex education programs for both school and parents so that teachers and parents can guide these students appropriately.

Journal of Korean Neurosurgical Society 2004;36(4):306-309
OBJECTIVE: Despite advances in both operative techniques (endovascular coiling or surgical neck clipping), management of basilar artery aneurysms has not been completed. The goal of this retrospective study is to evaluate endovascular coiling compared with surgical neck clipping of upper basilar artery aneurysms. METHODS: From january of 1990 to December of 2001, the authors treated 31 cases of upper basilar artery aneuryms. Among of those upper basilar artery aneurysms, 22 patients received surgical neck clipping and 9 patients recevied non-surgical endovascular coiling. Results from outpatient follow-ups for 12 months after operation were classified with Glasgow outcome scale (GOS) analyzed respectively. RESULTS: Overall, 11(50%) of the surgical neck clipping patients and 6(66.7%) in endovascular coiling patients were showed good outcomes(GOS 4~5). Morbidity of the surgical clipping is about 22.7%(5/22) and the endovascular coiling is about 22.2%(2/9) There were two death in the surgical clipping group due to vasospasm and brain stem infarction, but none in the endovascular coiling group. The major causes of surgical morbidity were direct brain damage, perforator occlusions, vasospasm and meningitis. Endovascular coiling group was shorter hospital stay and lesser hospital expenses than surgical neck clipping group. CONCLUSION: Non-surgical endovascular coiling of upper basilar artery aneurysms is considered to be useful alternative treatment in improving short-term prognosis(12 months follow-ups) and reducing medical expenses compared to surgical neck clipping although long-term follow-up is needed.

PURPOSE: This study was conducted to develop health education program components for early childhood and to investigate teachers' awareness of the importance of health education and their performance rate of health education. METHODS: Early childhood health education program components were developed using two rounds of the Delphi method. The Delphi group consisted of 21 experts in childhood education. After health education program components were developed, they were used in surveying child care teachers' awareness of importance and performance rate and 151 teachers sampled from 30 child care centers participated in the survey. RESULTS: The early childhood health education program components consisted of 5 areas, 16 subjects and 33 specific contents. Early childhood teachers' awareness of importance was over 4.5 points in all the areas and in 11 out of the 16 subjects. The most frequently educated subjects were 'the importance of hand washing' and the least frequently educated subject was 'obesity prevention'. The teachers' awareness of importance and their performance rate of specific contents were high in 'maintaining order' and 'using children's rides safely,' and low in 'obesity prevention' and 'infectious disease prevention.' CONCLUSION: The components of this health program were developed in consideration of field feasibility and the relationship of health program education in elementary, middle and high school.

PURPOSE: This study was to investigate the relationship between the level of emotional labor and occupational job stress of hospital nursing staff. METHODS: The survey was conducted from Mar. to Oct. 2009 to collect data from clinical nurses (N=496). RESULTS: The study showed that nurses without religion and those working in big-sized hospitals had higher scores in emotional labor, and those of 26~30 years old felt the highest stress in the occupational role. The same applied to the married, more work experienced, atheist and those working in big-sized hospitals. Unmarried, under educated nurses with less work experience working in the big-sized hospitals showed higher scores in personal strain. The scores of the personal resources depended on religion, work experience, marital status and position of their jobs. Emotional labor was positively correlated with an occupational role and personal strain, respectively, but the emotional labor, occupational role and personal strain were negatively correlated with personal resources respectively. CONCLUSION: Intervention program is required to reduce overload of nurse's role and to relieve physical and psychological strains of the under-30-age-group. Also, social support and rational/cognitive coping must be reinforced.

PURPOSE: This study was to develop and evaluate a health promotion program for women with osteoarthritis. METHODS: The research adopted the nonequivalent control group pretest-posttest design. The subjects were 34 in the experimental group and 34 in the control group sampled among vulnerable women aged over 40. The independent variable was the health promotion program, and the dependent variables were perceived health status, balance, K-WOMAC, depression, life satisfaction and health promoting behavior. The health promotion program was performed for 50minutes each session, twice a week and for 8 weeks. Data were collected from July 1 to September 11, 2010. RESULTS: The experimental group showed significant differences in perceived health status, balance, WOMAC pain, WOMAC difficulty of performing activity, depression, and health promoting behavior compared to the control group. There was no significant difference in WOMAC stiffness, waist, weight, and life-satisfaction. CONCLUSION: The results of this study suggest that the health promotion program can be applied in degenerative arthritis education to improve self-care.

PURPOSE: Recently, there are many good reports on the arthroscopic management of tibial condylar fractures. But, it may be appropriate for selected tibial condylar fractures and also needs a skilled technique. So we report the results of the tibial condylar fractures treated by the arthroscopy and limited percutaneous fixation or the arthroscopic-assisted management with conventional internal fixation without arthrotomy. MATERIALS AND METHODS: From June 1996 to December 1997, we treated 22 cases of the tibial condy- lar fractures including relatively comminuted one and analysed the results of patients who have been observed at least 1 year with Porters knee evaluation criteria. RESULTS: In 18 out of 22 cases, the results were Acceptable on symptoms(excellent 3, good 15, fair 4), in 18, on function(excellent 10, good 8, fair 3), in 21, on appearance(excellent 12, good 9, fair 1) and in 20, on radiographic appearance(excellent 11, good 9, fair 2). Overall results were Acceptable in 18 cases(82%) and Unacceptable in 4 cases(18%). CONCLUSION: The arthroscopic-assisted management with conventional internal fixation without arthrotomy can be the recommendable treatment for the tibial condylar fractures, including relatively comminuted one, without complications.

Clinics in Orthopedic Surgery 2020;12(3):324-329
Background:
The aim of this study was to evaluate the difference between the planned and verified actual values in total knee arthroplasty (TKA) performed using a navigation system.
Methods:
Sixty patients who underwent primary TKA for knee pain from March 2018 to July 2018 were included in this study.All patients underwent TKA using the latest version of a computer navigation system (Kick ver. 2.6). All TKA procedures were performed by the same surgeon. The appropriateness of the use of navigation system in each of the several steps during the operation was investigated. Implant size was assessed using a preoperative template and after registration of landmarks with the navigation system. Intraoperative measurement was conducted using a femoral sizing implant apparatus. The difference between the planned value based on the navigation system and the actual cutting value was investigated. Intraoperatively confirmed hip-knee-ankle angle was also compared to the angle measured at postoperative 3 months.
Results:
The average time spent on the registration process was 242 seconds (range, 205–345 seconds). Intraoperative femoral component size tended to be smaller than the size recommended by the navigation system. A significant difference between the planned distal femoral cutting level (9.08 ± 0.40 mm) and the verified actual cutting level (9.87 ± 1.39 mm) was identified (p < 0.05).The difference between the planned lateral and medial tibial resection levels (10.12 ± 0.34 mm and 4.47 ± 2.17 mm, respectively) and the verified actual lateral and medial tibial resection levels (9.07 ± 1.45 mm and 3.48 ± 2.00 mm, respectively) was statistically significant. Distal femoral cutting angle in sagittal plane was significantly different but femoral and tibial cutting angles showed no significant difference between the planned and verified values. At full extension, the average coronal alignment of the implant recorded after insertion of the actual implant using the navigation system was 0.23° ± 0.51° varus and showed no significant difference from the alignment measured at postoperative 3 months (0.45° ± 0.58°).
Conclusions
When performing navigation-assisted TKA, surgeons should aware that frequent errors can occur on the femoral cutting level, tibial cutting level, and implant sizing despite its reported advantage in defining the mechanical limb axis.

The authors reviewed findings of enhanced abdominal computed tomographic (CT) scans to the difference between a higher dose of conventional ionic contrast media(iothalamate meglumine) and a lower dose of a new, nonionic contrast material (ioversol). One hundred adult patients were divided into two groups. Each group consisted of 50 patients. Iothalamate meglumine and ioversol were intravenously administered in each group. The ratio of the male to female in the former was 28.22, and the latter 29:21. We examine the degree of renal streak artifact and measure the Hounsfield number of urine in renal collecting system. There were significant differences of the degree of the streak artifact depending upon the osmolality of contrast media used and that was related with urine CT number (P value<0.005). We authors conclude that nonionic low osmolar contrast media is prone to cause streak artifacts and distortions of renal image than conventional ionic high osmolar contrast media.
