Thoracic outlet syndrome is actually a collection of syndromes brought about by abnormal compression of the neurovascular bundle by bony, ligamentous or muscular obstacles between the cervical spine and the lower border of the axilla. First of all a syndrome is defined as a group of signs and symptoms that collectively characterize or indicate a particular disease or abnormal condition. The neurovascular bundle which can suffer compression consists of the brachial plexus plus the C8 and T1 nerve roots and the subclavian artery and vein. The brachial plexus is the network of motor and sensory nerves which innervate the arm, the hand, and the region of the shoulder girdle. The vascular component of the bundle, the subclavian artery and vein transport blood to and from the arm. the hand. the shoulder girdle and the regions of the neck and head. The bony, ligamentous, and muscular obstacles all define the cervicoaxillary canal or the thoracic outlet and its course from the base of the neck to the axilla or arm pit. Look at the scheme of this region and it all becomes more easily understood. Compression occurs when the size and shape of the thoracic outlet is altered. The outlet can be altered by exercise, trauma, pregnancy, a congenital anomaly, an exostosis, postural weakness or changes. Thoracic outlet syndrome has been described as occurring in a diverse population. It is most often the result of poor or strenuous posture but can also result from trauma or constant muscle tension in the shoulder girdle. The first step to beginning any treatment begins with a trip to the doctor. Make a list of all of the symptoms which seem to be present even if the sensations are vague. Make a note of what activities and positions produce or alleviate the symptoms and the time of day when symptoms are worst. Also, note when the symptoms first appeared. This list is important and should also include any questions one may have.

Objectives: Ssanghwa-tang (SHT) is a traditional herbal formula comprising nine medicinal herbs, and it is used for reducing fatigue in Korea. SHT exerts various effects such as anti-inflammatory, antioxidant, and anti-aging activities, and protection against acute hepatotoxicity. However, the genotoxicity of SHT has not yet been established. Methods: Ten components were identified in SHT water extract by using high-performance liquid chromatography analysis. We assessed the genotoxicity of SHT by using bacterial reverse mutation (Ames test), chromosome aberration, and in vivo micronucleus tests. Results: The contents of paeoniflorin, glycyrrhizin, and liquiritin apioside in SHT were 15.57, 6.94, and 3.48 mg/g extract, respectively. SHT did not increase the revertant colonies of Salmonella typhimurium and Escherichia coli strains in the presence or absence of metabolic activity. Although SHT did not induce structurally abnormal chromosomes in Chinese hamster lung (CHL) cells in the presence of metabolic activity, the number of structurally aberrated chromosomes increased dose-dependently in the absence of metabolic activity. In the in vivo micronucleus test, SHT did not affect the formation of micronuclei compared with the vehicle control. Conclusions: Genotoxicity of SHT was not observed in the Ames test and in vivo micronucleus test. However, based on the results of chromosome aberration test, it can be presumed that SHT has the potential to induce genotoxicity because it induced structurally abnormal chromosomes in the absence of metabolic activity.

Exposure to environmental toxicants can cause cellular problems including the interference of DNA repair processes which may lead to the development of cancer. The existence of toxicant-induced DNA repair abnormality was investigated using mice exposed in vivo to genotoxic chemicals and then challenging their exposed lymphocytes in vitro with bleomycin. The repair of bleomycin-induced DNA damage as estimated by the frequency of chromosome aberrations was determined. Our data indicates that the observed aberration frequencies after in vivo exposure to N-methyl-N'-nitro-N-nitnsoguanidine (MNNG) and in vitro challenge with bleomycin are consistently higher than expected. The enhanced response is not due to the induction of chromosome damage by 25 or 50 mg/kg MNNG since the chemical did not cause chromosome aberrations in lymphocytes of these mice. The observed response after the combined exposure to benzo[a]pyrene (BP) and bleomycin was significantly lower than expected with low in vivo doses of BP (50 mg/kg) and then significantly higher than expected with the high doses (200 mg/kg). We interpret our data to indicate that in vivo exposure to genotoxic agents can cause abnormal DNA repair activities. The response is, however, independent of the clastogenic activities of the inducing chemicals, but dependent upon the inducing agents and on the exposure doses.

The study is carried out to investigate the effect of drinking and smoking for the activities of aspartate aminotransferase(AST, or GOT) and alanine aminotransferase(ALT or GPT), from December 25, 1986 to April 30, 1987. The male physical examinees for employment, 900 who had visited to the Taegu Medical Center were subjected. And the positive cases of HBs-Ag, Anti-HBs and skin test for Clonorchis sinensis were excluded. The general characters of drinking and smoking pattern were introduced by interview with questionnaire provided for. In drinking cases, the longer duration was significantly effected the higher rate of abnormality in AST and ALT level. But the amount and the frequency were not. It was not appeared effects by mackgulri which is a Korean traditional wine and small amount of beers. In smoking cases, also same pattern. The age was related in all cases. By the way, when the effect is related the positive results with other factors: HBs-Ag, Anti-HBs, skin test for Clonorchiasis and harmful occupational history, it is higher abnormal rate of AST and ALT in the duplicated cases with two factors or more. Particularly in HBs-Ag positive cases, those who had smoking was the highest in rate of abnormality, and drinking was the follows. In correlation matrix among seven factors; HBs-Ag, age, drinking amount, drinking period, drinking frequency, smoking amount and smoking period, correlation coefficient was significant between the abnormal rate and to with age, drinking period, smoking period, and smoking amount.

With well-being boom recently, the common people, but not experts, are increasingly taking in them directly by picking wild herbs. However, only experts can distinguish between edible vegetables and poisonous herbs from the wild herbs. Especially, it is not even easy for experts to distinguish them only by looking into buds in spring without flowers or fruit. So, sometimes many patients are being carried into the emergency room by the toxic symptom after taking by misunderstanding the poisonous herbs as edible vegetables. For herb intoxication as well as drug intoxication, what kinds of vegetables patients took in, and when and how much they took in them are important information for curing. Of course, in the case of intoxicating in the wild herbs, the patients can have a lot of symptoms and sings-hemodynamic alteration and abnormal neurologic sign as well as gastrointestinal symptoms-according to the kinds of herbs which they took in. Therefore, it is difficult to find the kinds of herbs which they took in through the specific symptoms. Recently we experienced a case with showing typical anticholinergic symptoms after ingestion of Scopolia japonica. As a result, the publicity activities about the wild plants needs because if the person without their previous knowledge take in the poisonous herbs, serious side effects can be produced..

The rapid increase of the elderly living alone is a critical issue in worldwide as it leads to a rapid increase of a social support costs (e.g., medical expenses) for the elderly. In early stages of dementia, the activities of daily living (ADL) including self-care tasks can be affected by abnormal patterns or behaviors and used as an evidence for the early diagnosis. However, extracting activities using non-intrusive approach is still quite challenging and the existing methods are not fully visualized to understand the behavior pattern or routine. To address these issues, this research suggests a model to extract the activities from coarse-grained data (spatio-temporal data log) and visualize the behavioral context information. Our approach shows the process of extracting and visualizing the subject's spaceactivity map presenting the context of each activity (time, room, duration, sequence, frequency). This research contributes to show a possibility of detecting subject's activities and behavioral patterns using coarse-grained data (limited to spatio-temporal information) with little infringement of personal privacy.

The focus of this investigation was diet, weight control, health activities and the stress degree of students. The data was collected through a questionaire conducted from December 1, 1997 to December 20, 1997. The subjects of the survey were 1093 high school students in Seoul. The data was asalyzed using the SPSS WIN program, and the results are as follows: 1. 34.6% of girl high school students had abnormal dietst, and mos students ate snacks at least once a week. 2. According to the BMI Index, 5.8% of high school girls were overweight (not obese), but 41.3% thought of themselves as being fat. 91.4% of high school girls were concerned with weight control and 53.6% tried to control their weight. 3. Most of the surveyed students showed that they were concerned about their health. However, their activities including diet control (26.4%), balanced nutrition (26.1%) and regular exercise (10.7%) showed a low performance. 4. The degree of stress was measured and the highest level of stress was school work, followed by homelife, friendship and boyfriend etc. Stress levels were comparatively higher in third year students. 5. In general, when one looks at the health performance and stress levels, those who controled their food intake and were concerned about their health had higher stress levels. 6. Those who were concerned with weight control and those who tried to control their weight experienced the highest levels of stress from school work, homelife, friendship and other friends.

Background: Scapular posterior tilt (SPT) is important in the prevention of abnormal scapular movement and pain during elevation of the arm. However, previous studies have overlooked increased upper trapezius (UT) muscle activity interrupting the normal force couple of scapular motion and compensation of levator scapulae (LS) muscle activated simultaneously with UT during SPT exercise. Objects: The purpose of this study was to compare the effects of modified SPT with depression exercise versus SPT exercise on serratus anterior (SA), lower trapezius (LT), UT, and LS muscle activities and the clavicular tilt angle, in subjects with rounded shoulder posture (RSP) and myofascial pain in the UT muscle region. Methods: Eighteen subjects with RSP were recruited and randomly allocated to 2 groups; 9 in the SPT group and 9 in the SPT with depression group. All subjects met the specific RSP criteria and had myofascial pain of UT region. Depending on the allocated group, subjects performed the assigned SPT exercise and EMG data were recorded during the each exercise. Clavicular tilt angle was defined as the angle between the line joining the medial and lateral end of the clavicle and a horizontal line. Results: The SA muscle activity was significantly greater in SPT with depression than with SPT exercise (p<.05). The UT, LS muscle activity and the clavicular tilt angle was significantly lower in SPT with depression than with SPT exercise (p<.05). Conclusion: These findings were insightful because the potential risk of pain from overactivation of the UT and LS was considered, in contrast with SPT exercise. SPT with depression exercise can be implemented as an effective method to facilitate scapular muscle activity for stability and to prevent myofascial pain in the neck and shoulder.

These days there is a constant possibility of exposure to UV radiation which can cause abnormal production of melanin and result in skin disease such as hyperpigmentation and melanoma. Many materials were investigated for skin whitening and protection against UV radiation. In this study, we assessed the melanogenesis inhibitory activities of Korean Red Ginseng (KRG, Ginseng Radix Rubra) and Ginkgo (EGb 761 Ginkgo Biloba) in an attempt to develop a new skin whitening agent derived from natural products. B16F10 melanoma cells were treated for 48 hr with KRG and EGb 761. The inhibitory effect on melanogenesis was measured and related cytokines and proteins expression were also investigated by RT-PCR and Western blotting. In addition, we also assessed the effects of these substances on the skin of C57BL/6 mice. Cell growth, melanin content and tyrosinase activity were inhibited effectively in B16F10 melanoma cells treated with KRG and EGb 761. Moreover, tyrosinase mRNA expression was inhibited clearly and melanogenesis related proteins (MRPs) containing tyrosinase, TRP1 and TRP2 were also reduced by KRG and EGb761, while cytokines such as IL-$1{\beta}$ and IL-6 were induced. In the case of UV irradiated mice, we observed induction of cytokine mRNA levels and reduction of MRPs mRNA expression. In addition, a decrease in pigmentation from treatment with KRG and EGb 761 on the skin of mice was observed. These results indicate that KRG and EGb 761 inhibit melanogenesis in B16F10 cells and have display protective activities against UVB. Therefore, we suggest that KRG and EGb 761 are good candidates to be used as whitening agents and UVB protectors for the skin.
