The purpose of this study was to examine the influence of the exercise performance of yoga and pilates on the autonomic nervous system in an effort to provide some clinical information on exercise prescription. The subjects were 20 selected college students who majored in P.E. A yoga group and a pilates group were organized with 10 students respectively, the autonomic nervous system of the students was measured before the exercise, immediately after that and 30 minutes after recovery. The findings of the study were as follows: First, there were significant differences in the yoga group's stress index and average pulse according to the main effect of the time and interaction effect between the time and group. Second, there were significant differences in the yoga group's sympathetic nervous system activity and autonomic nerve balance according to all the main effect of the time, interaction effect between the time and group and the main effect of group. Third, there were significant differences in HRV(Heart Rate Variability), parasympathetic nervous system activity, SDNN, and RMSSD according to the main effect of the time, and interaction effect between the time and group and the main effect of group produced no statistically significant differences. In conclusion, yoga seemed to be effective at lowering stress index and average pulse. Specifically, yoga exercise seemed to exert a more positive influence on the decrease of sympathetic nervous system activity and autonomic nerve balance than pilates exercise.

Recently Atopic Dermatitis(AD) is increasing along with allergic disease. At present, there is no infallible cure for AD. Then AD patients undergo great suffering. This study is carried out to see whether or not the administering Danggwieumja(DG) along with Samhwangseje-gamibang(SG} as a medicine for external aplication, is effective in treating atopic dermatitis. To examine the effectiveness of the above prescription, the author made an observation of diverse immune responses. through the model of NC/Nga atopic mice. Results provided evidence that the DG administration along with SG can be used as a treatment means to atopic dermatitis. The results are as follows: The extent of Clinical skin severities in 13 and 16 week old NC/Nga mice treated with DG and SG, were reduced by 50.9%, 53.9% respectively, compared to the control NC/Nga mice with no drug treatment. IgE, IL-4, IL-5, IL-6, IgM and IgG1 levels in the serum of the NC/Nga mice treated with DG and SG were significantly decreased compared to those of the untreated control mice. In contrary, to the $IFN-{\gamma}$ level, significantly increased. The spleen weight of the NC/Nga mice treated with DG and SG significantly decreased compared to those of the untreated control mice. CCR3 gene expression in the skin tissue of NC/Nga mice treated with DG and SG were highly decreased, and the IL-6 expression significantly decreased, and the $IFN-{\gamma}$ gene expression increased compared to those of the untreated control mice. Histological observation of the ear and dorsal skin tissue of the NC/Nga mice treated with DG and SG, showed that the extents of inflammation and infiltrated immune cells in the epidermal tissue and dermis, were highly reduced compared to those of the untreated control mice. In the model inducing COX-2 activity in RAW 264.7 cell, the denser DG became, the more COX-2 activity was inhibited, compared to those of the untreated control group. $IL-1{\beta}$, and $TNF-{\alpha}$, IL-6 gene expression in RAW 264.7 cell with DG, significantly decreased, compared to those of the untreated control group. According to the assessment of cell toxicity in L929 cell, the rate of cell multiplication increased by 3% in consistency to 100ppm of DG compared to the untreated control group and in more than the 200 ppm consistency, cell toxicity was occurred.

Objectives : To estimate the economic burden of osteoporotic vertebral fracture (VF) from a societal perspective. Methods : From 2002 to 2004, we identified all National Health Insurance claims records for women ${\geq}50$ years old with a diagnosis of VF. The first 6-months was defined as a "clearance period," such that patients were considered as incident cases if their first claim of fracture was recorded after June 30, 2002. We only included patients with ${\geq}$ one claim of a diagnosis of, or prescription for, osteoporosis over 3 years. For each patient, we cumulated the claims amount for the first visit and for the follow-up treatments for 1 year. The hospital charge data from 4 hospitals were investigated to measure the proportion of the non-covered services. Face-to-face interviews were conducted with 106 patients from the 4 study sites to measure the out-of-pocket spending outside of hospitals. Results : During 2.5 years, 131,453 VF patients were identified. The patients had an average of 3.38 visits, 0.40 admissions and 6.36 inpatient days. The per capita cost was 1,909,690 Won: 71.5% for direct medical costs, 20.6% for direct non-medical costs and 7.9% for indirect costs. The per capita cost increased with increasing age: 1,848,078 Won for those aged 50-64, 2,084,846 Won for 65-74, 2,129,530 Won for 75-84and 2,121,492 Won for those above 84. Conclusions : Exploring the economic burden of osteoporotic VF is expected to motivate to adopt effective treatment options for osteoporosis in order to prevent the incidence of fracture and the consequent costs.

Free radicals are thought to be the most important cause of the reperfusion injury subsequent to ischemia. The antioxidant status of the tissue affected by ischemia-reperfusion is of great importance for the primary endogenous defense against the free radical induced injury. Therefore, antioxidant therapy has been shown to be beneficial in neurological disorders such as Alzheimer's disease and cerebral ischemia. In this study, the protective effects of Chungpesagan-tang (CST) was investigated against ischemia/reperfusion-induced cytotoxicity in SK-N-MC neuronal cells It was found out that low concentration of CST was highly effective in protecting neuronal cells against ischemia/reperfusion-induced cytotoxicity. The inhibitory effect of CST on malondialdehyde formation during ischemia/reperfusion-induced oxidative stress in SK-N-MC cells showed obvious dose-dependent responses. Also, CST showed relatively high inhibitory activity to xanthine oxidase induced by ischemia/reperfusion environment Therefore, it is thought that CST has both antioxidant and xanthine oxidase inhibitory effect and can be used for clinical applications for protection of neuronal cells from ischemia-reperfusion injury.

The application of more complex radiotherapy techniques using multileaf collimation (MLC), such as 3D conformal radiation therapy and intensity-modulated radiation therapy (IMRT), has increased the significance of verifying leaf position and motion. Due to thier reliability and empirical robustness, quality assurance (QA) of MLC. However easy use and the ability to provide digital data of electronic portal imaging devices (EPIDs) have attracted attention to portal films as an alternatives to films for routine qualify assurance, despite concerns about their clinical feasibility, efficacy, and the cost to benefit ratio. In this study, we developed method for daily QA of MLC using electronic portal images (EPIs). EPID availability for routine QA was verified by comparing of the portal films, which were simultaneously obtained when radiation was delivered and known prescription input to MLC controller. Specially designed two-test patterns of dynamic MLC were applied for image acquisition. Quantitative off-line analysis using an edge detection algorithm enhanced the verification procedure as well as on-line qualitative visual assessment. In conclusion, the availability of EPI was enough for daily QA of MLC leaf position with the accuracy of portal films.

Purpose: Recently, complementary and alternative medicine (CAM) has been increasingly used in children. Studies have shown that 34% of adults and 11% of children use CAM in the USA and Canada. The purpose of this study was to investigate the prevalence and patterns of CAM use in elementary children in Korea. Methods:From July to August 2007, parents of elementary children completed a questionnaire survey at Gwang-ju. In all, 794 questionnaires were analyzed. Results:Of the 794 respondents, 278 answered that their pupils (35%) had experienced CAM. The following types of CAM therapy were used: herbal medicine, 62.5% dietary supplements, 31.2% vitamins, 30.2% and acupuncture, 11.1%. CAM therapies were used for the following diseases: nutritional deficiency, 33.3% atopic dermatitis, 31.3% arthralgia, 31.3% allergic rhinitis, 28.8% obesity, 26.3% and asthma. The following were the motives to use CAM: prevention of diseases (33.5%), dissatisfaction with modern medicine (21.2%), and complementary therapy to modern medicine (20.5%). People gained information about CAM through neighbors (65%) and mass media (21%). Moreover, 83 parents (30%) were satisfied with CAM because of its effectiveness. Conclusion:Many parents have advocated the use of CAM in their children. However, most of them used CAM without any prescription or adequate knowledge. Further studies are required to determine the efficacy of CAM.

In order to provide a basis for studying the molecular mechanism of pharmacological action of local anesthetics and to develop a fluorescence spectroscopic method which can detect the microviscosity of native and model membranes using intramolecular excimerization of 1,3-di(l-pyrenyl)propane (Py-3-Py), we examined the effect of lidocaine HCl on the microviscosity of model membranes of phosphatidylcholine fraction extracted from synaptosomal plasma membrane vesicles (SPMVPC). The excimer to monomer fluorescence intensity ratio (I'/I) of Py-3-Py in liquid paraffin was a simple linear function of $T/{\eta}.$ Based on this calibration curve, the microviscosity values of the direct probe environment in SPMVPC model membranes ranged from $234.97{\pm}48.85$ cP at $4^{\circ}C$ to %19.21{\pm}1.11$ cP at $45^{\circ}C.$ At $37^{\circ}C,$ a value of $27.25{\pm}0.44$ cP was obtained. The lidocaine HCl decreased the microviscosity of SPMVPC model membranes in a concentration-dependent manner, with a significant decrease in microviscosity value by injecting the local anesthetic even at the concentration of 0.5 mM. These results indicate that the direct environment of Py-3-Py in the SPMVPC model membranes is significantly fluidized by the lidocaine HCl. Also, the present study explicitly shows that an interaction between local anesthetics and membrane lipids is of importance in the molecular mechanism of pharmacological action of lidocaine HCl.

Warfarin is the most widely used oral anticoagulant in the world but maintenance of proper therapeutic range and prevention of adverse drug events always need to be careful. Especially, in Korea, warfarin dosing for patients with cerebral infarction is currently based on the nomogram which is done by foreign clinical trials not for the Korean. Therefore we evaluate warfarin dose of patients in the neurology and eventually get the base data of warfarin nomogram for Korean with stroke. We performed this study retrospectively on reviewing the medical charts to evaluate the prescribed loading dose (LD) and maintenance dose (MD) of warfarin and each responding International Normalized Ratio (INR) with any bleeding adverse drug reaction including of patient's characteristics for total 75 patients with stroke in the department of neurology of Kangnam ST. Mary's Hospital from January 2005 to June 2008. All evaluated patients should not be treated with warfarin in the past at all and should be initiated warfarin therapy first.ly at this time. All evaluated patients were divided as two classes by wafarin LD which is; 1) HDG - a high loading dosing group prescribed over 5mg, and 2) LDG - a low loading dosing group prescribed 5mg or below. As a result, average LD was $9.34{\pm}0.22$ mg (p=0.000) in HDG and $4.25{\pm}0.39$ mg (p=0.000) in LDG. Average baseline INR was $0.91{\pm}0.05$ (p=0.161) in HDG and $1.26{\pm}0.14$ (p=0.002) in LDG. On the first and second week, daily MD was $4.21{\pm}0.14$ mg (p=0.000) and $2.96{\pm}0.19$ mg (p=0.696) in HDG and also in LDG, $2.95{\pm}0.29$ mg (p=0.000) and $3.14{\pm}0.36$ mg (p=0.696). Also average reacting daily INR was respectively $2.53{\pm}0.12$ (p=0.141) and $2.51{\pm}0.16$ (p=0.678) in HDG, and in LDG, $2.11{\pm}0.17$ (p=0.141) and $2.42{\pm}0.14$ (p=0.678). After the second week, INR was not measured in regularly. Also most of underlying diseases were hypertension (n=38), diabetes mellitus (n=14), dyslipidemia (n=8) in order. Four ADRs with simple hemorrhage were occurred and those were due to drug interaction by comedication. In the conclusion, proper starting LD for Korean with stroke is 10 mg if baseline INR is around 1.0 or 5 mg if over 1.3. Proper MD need to be more evaluated in the future for setting up warfarin nomogram to make prospective study.
