Sa-Sang, one of the Korean traditional medicines, classifies people's constitution into 4 types, which are referred to as Tae-Yang-In, Tae-Eum-In, So-Yang-In and So-Eum-In. The purpose of this study was to examine demographic and dietary factors and to test any significant differences between Sa-Sang constitution and related factors. The participants were 483 college students and the data of 428 students were finally analyzed. Constitution was determined identically through both the questionnaire on Sa-Sang constitution and an inquiry by a Korean traditional medical doctor. Tae-Eum-In showed statistically significant higher BMI and higher smoking frequency. Tae-Eum-In also had significantly higher intakes in iron, potassium, sodium, vitamin B$_1$, niacin, $\beta$-carotene and vitamin E. So-Eum-In had significantly lower intakes in protein, phosphorous, and folate. From this study, we could expect to get some scientific, objective and accurate diet information on the types of constitution. Considering the fact that most chronic degenerative diseases could be developed by any lifestyle factors, it is necessary to conduct educational programs about lifestyles including the dietary habit for maintaining good health. Therefore, it will be better to continue a long-term follow-up study on any chronic degenerative disease based on the types of Sa-Sang constitution in the future.

We compared and studied the results on two diagnostic machines called Yangdorack and EAV on 18 recovering paralytic patients. The results were as folIows ; 1. Patients with weak motor ability showed an average of 25% fewer units of Yangdorack and an average of 49% fewer units of EAV. 2. Deficiency/excess diagnostic results on meridian and internal organs showed 58.5% deficiency and 41.5% excess on the Yangdorack ; 67.9% of decline-degenerative activity and 32.1% of stimulus-inflarrunation activity on the EAV. 3. In the attack of meridian and internal organs in view of the five elements(五行), in rate of deficiency, decline and degeneration of the fire meridian(火經) in view of the highest rate accounts showed 19.5% on the Yangdorack and 20.4% on the EAV. 4. In comparing deficiency/excess results on the Yangdorack with results of decline-degenerative value and stimulus-inflammation value on the EAV, they both showes a 39% rate. 5. In comparing clinical syndromes on the Yangdorack and common diseases on the EAV, they showed a 72% agreement.

As the elderly population increases, the number of patients with various joint diseases, including degenerative arthritis, is steadily increasing. CPM medical devices are needed to effectively treat degenerative arthritis that is common in the elderly population. Domestic CPM medical devices have limited functions and are highly dependent on imports for expensive imported medical devices. To solve this problem, we designed a ROM measurement function using a current sensor that is not present in existing composite joint CPM medical devices. The algorithm was designed using the fact that the force caused by joint stiffness greatly increases the current flowing through the DC motor. In addition, the need for digital healthcare in the medical field is gradually expanding as the proportion of chronically ill patients increases due to the spread of the non-face-to-face economy due to COVID-19 and the aging population. Therefore, this paper aims to improve the performance of CPM medical devices by allowing real-time confirmation of rehabilitation exercise information and operation range measurement results in accordance with digital healthcare trends through a Bluetooth application developed as an Android studio.

This study was performed to investigate the prevalence of chronic disease and utilization of medical facility in rural area. 5,797 persons were randomly selected from 28,883 rural residents who were over 30 years old and living in Moonkyung city in Kyungsangpook Province during the period October 1 1983 to February 28 1994. The person prevalence rate was 336 per 1,000. The prevalence rate in men(278 per 1,000) was higher than that(388 per 1,000) in women. The spell prevalence rate in men(367) was significantly higher than that(429) in women (p<0.05). The prevalence was increased with the age, 106 in the 30's. 223 in the40's, 336 in the 50's, 407 in the 60's, and 457 in the age group of 70 above. Of all chronic diseases, the prevalence of neuralgia ranked first(128), chronic gastrointestinal disorders(64), degenerative arthritis(54). hypertension (44) and diabetes (14) were followed in descending order. In men, the prevalence of neuralgia ranked first, chronic gastrointestinal disorders, degenerative arthritis, hypertension and bronchial asthma were followed in descending order. In women, the prevalence of neuralgia ranked first, degenerative arthritis, chronic gastrointestinal disorders, hypertension and diabetes were followed in descending order. The prevalences of neuralgia, degenerative arthritis and hypertension were significantly higher in women than those in men, however, those of cardiovascular disease, pulmonary tuberculosis and liver cirrhosis in men were significantly higher than those in women(p<0.05). Most patients with chronic diseases were more likely to utilize hospital and/or local clinics than public health facility or community health providers. Patients with neuralgia, degenerative arthritis and bronchial asthma tended to utilizing local clinics initially, however, they were changed to visit public health facility or community health providers afterwards. Patients with hypertension or pulmonary tuberculosis were more likely to visit public health facility, however, those with diabetes, cancer, heart failure, CVD, liver cirrhosis were more likely to visit hospital.

Daejowhan-gamibang(DJG) is used to prevention and treatment of cerebrovascular disease, heart disease, dementia, hyperlipdemia circulatory disturbance. Korean traditional herbal prescriptions and herb medicines in neuronal cells, which have been used for the treatment of stroke and brain diseases in Korean traditional medicine were screened to study the antioxidant effects and its mechanism. Daejowhan-gamibang water extract(DJGWE) was tested on their antioxidant activity using radical scavenging effects against ABTS. It showed significant antioxidant capacities at 50㎍ concentration. The antioxidant activity of DJGWE was determined in the different concentration (10㎍, 50 ㎍, and 100㎍). At the same time, the antiperoxidation effects was determined. Lipid peroxidation in brain homogenates induced by NADPH and ADP-Fe/sup 2+/ was significantly inhibited by DJGWE in vitro. DJGWE showed a potent antioxidant and antiperoxidative activity, further investigation, in vitro and in vivo, will be needed for the confirm of possibility as an antioxidant therapeutic agents and their optimal treatment of brain diseases in human. In searching the mechanism of antioxidant effects of DJGWE, it showed the inhibition of activity of JNK, p38, ERK and caspase 3 induced by hypoxia. So, DJGWE should be surveyed for the use of the potential therapeutic prescription for stroke and brain degenerative diseases such as pakinson's disease, dementia.

This article schematically reviews the clinical features, diagnostic approaches to, and toxicological implications of toxic encephalopathy. The review will focus on the most significant occupational causes of toxic encephalopathy. Chronic toxic encephalopathy, cerebellar syndrome, parkinsonism, and vascular encephalopathy are commonly encountered clinical syndromes of toxic encephalopathy. Few neurotoxins cause patients to present with pathognomonic neurological syndromes. The symptoms and signs of toxic encephalopathy may be mimicked by many psychiatric, metabolic, inflammatory, neoplastic, and degenerative diseases of the nervous system. Thus, the importance of good history-taking that considers exposure and a comprehensive neurological examination cannot be overemphasized in the diagnosis of toxic encephalopathy. Neuropsychological testing and neuroimaging typically play ancillary roles. The recognition of toxic encephalopathy is important because the correct diagnosis of occupational disease can prevent others (e.g., workers at the same worksite) from further harm by reducing their exposure to the toxin, and also often provides some indication of prognosis. Physicians must therefore be aware of the typical signs and symptoms of toxic encephalopathy, and close collaborations between neurologists and occupational physicians are needed to determine whether neurological disorders are related to occupational neurotoxin exposure.

The tumor necrosis factor-receptor 1 (TNFR1)-associated death domain protein (TRADD) contains an N-terminal TRAF binding domain and a C-terminal death domain. TRADD is known to interact directly with TNF receptor 2 (TNFR2) and the Fas-associated death domain protein (FADD), which are signal transducers that activate NF-${\kappa}B$ and induce apoptosis, respectively. To date, there has been no structural information on the TRADD and FADD death domain (DDs) complex. In this study, the death domains of TRADD and FADD were co-expressed and purified from Escherichia coli for structural characterization. We found that human TRADD (hTRADD) interacted strongly with mouse FADD (mFADD) via their DDs and interacted weakly with human FADD (hFADD)-DD. Moreover, the structures of the TRADD-DD:FADD-DD complexes were separately modeled from predicted structures in the protein data bank (PDB). The results of this study will have important applications in human diseases such as cancer, AIDS, degenerative and autoimmune diseases, and infectious diseases.

Green tea and coffee consumption have been widely popular worldwide. These beverages contain caffeine to activate the central nervous system by adenosine receptor blockade, and due to the caffeine, addiction or tolerance may occur. In addition to this caffeine effect, green tea and coffee consumption have always been at the center of discussions about human health, disease, and longevity. In particular, green tea catechins are involved in many biological activities such as antioxidation and modulation of various cellular lipid and proteins. Thus, they are beneficial against degenerative diseases, including obesity, cancer, cardiovascular diseases, and various inflammatory diseases. Some reports also suggest that daily consumption of tea catechins may help in controlling type 2 diabetes. However, other studies have reported that chronic consumption of green tea may result in hepatic failure, neuronal damage, and exacerbation of diabetes, suggesting that interindividual variations in the green tea effect are large. This review will focus on the effect of green tea catechins extracted from the Camellia sinensis plant on type 2 diabetes and obesity, and the possible mechanistic explanation for the experimental results mainly from our laboratory. It is hoped that green tea can be consumed in a suitable manner as a supplement to prevent the development of type 2 diabetes and obesity.

Oxidative stress brings about apoptosis through various mechanisms. In particular, oxidative stress in neuronal cells can causes a variety of brain diseases. This study was conducted to investigate the effect of Bidens tripartita on oxidative stress in neuronal cells. B. tripartita has traditionally been used in Russia as a medicine for diseases such as rhinitis, angina and colitis. Over-production of glutamate induces oxidative stress. When the oxidative stress occurs in the cells, reactive oxygen species (ROS) and Ca²⁺ increase. In addition, the abrupt decline of mitochondrial membrane potential and the decrease of glutathione related enzymes such as glutathione reductase (GR) and glutathione peroxidase (GPx) are also observed. The samples used in the experiment showed cytoprotective effect in the MTT assay. It also lowered the ROS and Ca²⁺ level, and increased degree of mitochondrial membrane potential, GR and GPx. As a result, B. tripartita had a positive effect against oxidative stress. Thus, it is expected to have potential for treatment and prevention of degenerative brain diseases such as Alzheimer's disease.

Objectives : Anterior cervical discectomy and interbody fusion has become a well-accepted surgical treatment of degenerative cervical diseases. Implatable cages have a stabilizing effect without plates and no need for autogenous bone graft. The authors evaluates the effect of implatable titanium cage(RABEA) on the clinical and radiological outcomes. Methods : 34 patients with symptomatic cervical degenerative diseases due to one level disc pathology were underwent anterior cervical discectomy and interbody fusion with titanium cages(RABEA) which were not filled with cancallous bone grafts from January 1999 to May 2001. Patients with osteoporosis and older than 65 years were not included. Among them, 15 patients could be followed-up for at least 1 year. The authors retrospectively reviewed the charts and radiographic data. Mean follow-up period was $1.3{\pm}0.2years$. Results : Clinical results according to the Odom's criteria was exellent and good in 14(93%) patients. One patient with fair result showed complete loss of the disc space height due to settlement of the cage. Preoperatively, the mean height of the disc space(${\pm}$standard deviation) was $3.42{\pm}1.10mm$(range 2.0-5.5mm), and at 1 day postoperatively it was $7.88{\pm}0.90mm$(range 6.50-9.0). The mean height of the disc space after 1 year was $6.50{\pm}1.38mm$(range 3.0-8.0). The restoration of the height was statistically significant(p<0.05). The mean height after 1 year was $82.7{\pm}15.9%$ of the height at 1 day postoperatively. Preoperatively the mean value of the cervical lodortic angle was $21.8{\pm}11.8^{\circ}$ and 1 year postopertively, it was $24.5{\pm}8.3^{\circ}$, which was statistically not significant. All patients showed no abnormal movements on flexion and extension lateral film after 6 months. Conclusion : Implantable titanium cages appear safe and effective in selected patients, and their use helps to avoid complications associated with bone graft harvest. Subsidence of the cage seems to be a potential risk factor for recurrence of the symptoms. For long-term results, a longer follow-up is required.
