과다한 음주는 알츠하이머 및 파킨슨 질병과 같은 각종 만성 퇴행성 뇌질환의 대표적인 원인 중 하나로 알려져 있다. 체내에 유입된 에탄올은 알코올 탈수소효소(alcohol dehydrogenase, ADH)에 의해 아세트알데히드로 대사된 후 다시 알데히드탈수소효소 2(aldehyde dehydrogenase 2, ALDH2)에 의해 아세트산으로 대사되어 배출된다. 에탄올의 대사과정 중에는 다량의 free radical이 생성되어 체내에서 산화적 스트레스를 유발하는 것으로 알려져 있고, 아세트알데히드는 활성산소를 생산하는 독성물질로 잘 알려져 있다. 본 연구에서는 8주간 에탄올에 노출된 Aldh2 knockout 마우스를 사용하여 ALDH2 효소 활성이 뇌 조직과 소변의 지질과산화에 미치는 영향에 대하여 살펴보았으며, 지질과산화 정도를 측정하기 위해 HPLC를 통한 TBARS 정도를 측정하였다. 연구결과, 마우스에서 만성 에탄올 섭취는 뇌 조직 TBARS 생성에 영향을 주지 않는 것으로 나타났으나, 소변 TBARS는 Aldh2 (-/-) 마우스에서 에탄올을 투여함에 따라 유의한 증가를 보였다(p<0.05). 본 연구 결과로부터 8주간 에탄올을 경구 투여한 마우스에서 ALDH2의 활성은 체내의 전반적인 활성산소 생성에는 중요하게 관여하는 것으로 보이지만 뇌조직에서의 활성산소 생성에는 영향을 주지 않는 것으로 보이며, 이는 에탄올 노출과 이에 따른 활성산소가 다양한 만성 뇌질환을 유발한다는 기존의 가설에서 ALDH2의 활성이 중요하게 관여하지 않을 가능성을 시사한다.

The aims of this study were to understand and to predict the determinent factors affecting the exercise behaviors and physical fitness by testing the Pender's revised health promotion model, and to help the patients with rheumatoid arthritis and osteoarthritis perform the continous exercise program, and to help them maximize the physical effect such as muscle strength, endurance, and functional status and mental effects including self efficacy and quality of life, and improve the physical and mental well being, and to provide a basis for the nursing intervention strategies. Of the selected variables in this study, the endogenous variables included the physical fitness, exercise score, exercise participation, perceived benefits of action, perceived barriers of action to exercise, activity-related affect(depression) and perceived self-efficacy, interpersonal influences(family support), situational factors(duration of arthritis, fatigue) and the exogenous variables included personal sociocultural factor(education level), personal biologic factor(body mass index), personal psychologic factor(perceived health status) and prior related behavior factors(previous participation in exercise, life-style). We analyzed the clinical records of 208 patients with rheumatoid arthritis and degenerative arthritis who visited the outpatient clinics at H university hospital in Seoul. Data were composed of self reported qustionnaire and good of fitness score which were obtained by padalling the ergometer of bicycle for 9 minutes. SPSS Win 8.0 and Window LISREL 8.12a were used for statistical analysis. Of 75 hypothetical paths that influence on physical fitness, exercise participation, exercise score, perceived benefits of action, perceived barriers of action to exercise, activity-related affect(depression) and perceived self-efficacy, interpersonal influences(family support), situational factors(duration of arthritis, fatigue), 40 were supported. The physical fitness was directly influenced by life-style, perceived health status, education level, family support, fatigue, which explained 12% of physical fitness. The exercise participation were directly influenced by life-style, education level, past exercise behavior, perceived benefits of action, perceived barriers of action, depression and duration of arthritis, which explained 47% of exercise participation. Exercise score were directly affected by perceived self efficacy. BMI, life-style, past exercise behavior, perceived benefits of action, family support, perceived health status. perceived barriers of action, and fatigue, which explained 70%. Perceived benefits of action was directly influenced by BMI, life-style, which explained 39%. Perceived barriers of action were directly influeced by past exercise behavior, perceived health status, which explained 7%. Perceived self efficacy were directly influeced by level of education, perceived health status, life-style, which explained 57%. Depression were directly influeced by past exercise behavior, BMI, life-style, which explained 27%. Family support were directly influeced by life-style, perceived health status, which explained 29%. Fatigue were directly influeced by BMI, life-style, perceived health status. which explained 41%. Duration of arthritis were directly influeced by life-style, past exercise behavior, BMI, which explained 6%. In conclusion, important variables for physical fitness were life-style, and variable affecting exercise participation were life-style. Perceived self-efficacy of exercise was a significant predictor of exercise score. BMI, Life-style, perceived benefits of action, family support, past exercise behavior showed direct effects on perceived self-efficacy. Therefore, disease related factor should be minimized for physical performance and well being in nursing intervention for patients with rheumatoid arthritis, and plans to promote and continue exercise should be seeked to reduce disability. In addition, Exercise program should be planned and performed by the exact evaluation of exercise according to the ability of the patients and the contents to improve the importance of exercise and self efficacy in self control program, dedicated educational program should be involved. This study suggest that the methods to reduce the disease related factors, the importance of daily life-style, recognition of benefit of exercise, and educational program to promote self efficacy should be considered in the exercise behavior promotion and nursing intervention for continous performance. The significance of this study is also thought to provide patients with chronic arthritis the specific data for maximal physical and mental well being through exercise, chronic therapeutic procedure, daily adaptation and confrontation in nursing intervention.

This study aimed at investigating correlation of nutrients intake and serum lipids of industrial workers. 226 for adult aged 20yr~59yr (average age 35.9yr) were selected as subjects during 6 months, from June to December, 1997. Nutrients intake was investigated by questionnaire, 24-hour recall method. Antropometric assessments, serum lipids and blood pressure of the subjects were investigated. The results as follows ; In total subjects, calories, calcium, vitamin A, vitamin $B_1$, and vitamin $B_2$ were below Korean RDA(recommended dietary allowances) and protein, iron, vitamin C, niacin and phosphorus were above Korean RDA. Distribution of BMI groups were underweight groups(7.9%), normalweight groups(63.3%) and overweight groups(28.8%). In BMI groups, intakes of calories, carbohydrates, protein, fats, iron, niacin and potassium of overweight groups were higher than those of other groups, significantly(P<0.001). Intakes of calcium of underweight groups were lower than those of other groups, significantly(P<0.05). BMI increased with age. Total cholesterol, triglyceride, apo(b) and atherogenic index of overweight groups were higher than those of other groups, significantly(P<0.001). Calories, carbohydrates, protein, fats, iron, vitamin $B_1$, vitamin $B_2$, niacin, natrium and potassium were positively correlated with BMI, significantly(P<0.001). Calcium and vitamin C were positively correlated with BMI, significantly(P<0.01). vitamin A and phosphorus were positively correlated with BMI, significantly(P<0.05). Total lipid, total-chol., triglyceride, apo(b) and atherogenic index were positively correlated with BMI, significantly(P<0.001). HDL-chol. were negatively correlated with BMI, significantly(P<0.001). Above results, the more BMI and age increased, the worse patterns of serum lipid, so that increased atherogenic index that increased risk of atherosclerosis and degenerative chronic disease connected with serum lipid. After classified by BMI, age and lipid pattern, it will be managed individually for health management of industrial workers. Development and application of efficient program will be urgent for harmonious nutrition counseling and guidance.

The objectives of this study were to conduct preliminary research to investigate full course meals in Korean style restaurants in order: i) to analyze the nutrient contents of full course meals per servings, and ii ) by analyzing the above, to examine the amount and the quality of the foods served in the full course meals by two different types of Korean style restaurants. A total of 27 restaurants participated in this study, 7 restaurants from the luxurious hotels in Seoul and 20 restaurants from the City of Changwon. A key finding was that restaurant patrons tended to overconsume nutrients as compared to the Korean Recommended Daily Allowance (RDA), and restaurants generated large amounts of food wastes due to the excess food served. Other findings were as follows: 1) Compared with 1/3 or the Korean RDA, all the nutrients were oversupplied. The average nutrient ratios were about 3.7 times higher than 113 of the Korean RDA in calories, about 9 times higher in proteins, 10 times higher in phosphorus, 7 times higher in Vitamin Bl, and 12 times higher in Vitamin E. 2) Seventy-five percent (n = 20) of the restaurants served within the range of thirty to forty dishes, whereas most of the hotel restaurants (70%) served twenty dishes or fewer. 3) The average carbohydrate: protein: fat (CPF) ratio of caloric nutrients was 40：26 : 34. This study concluded that: i) Korean style full course meals provide too much food, nutrients, and calories, resulting in an over- or unbalanced nutrient intake, and ii ) the Korean style full course meals consisted of a high-protein, high-fat and high-caloric intake, which is similar to a westernized caloric nutrient pattern. Such over -or unbalanced nutrient intake could cause chronic degenerative problems such as cancer and cardiovascular disease. These findings indicate that restaurants serving Korean style full course meals should carefully plan their menus in order to provide their customers with balanced meals. They should also be strongly encouraged to play an active role in improving their customers' nutritional status, as well as reducing the restaurants wastage of food. Lastly, further research should be conducted to improve the quality of the menus in Korean restaurants. (Korean J Community Nutrition 8(3) : 327∼339, 2003)

This study was designed to investigate the effects of sea tangle (Laminaria japonica) extract and fucoidan components on anti-aging action. Sprague-Dawley(SD) male rats (210$\pm$5g) were fed experimental diets Dasi-Ex group: sea tangle extract powder of 4.0% added to control diet; Fuco-I, II and III groups: funcoidan powder of 1, 2 and 3% added to Dasi-Ex group for 45 days. Hydroxyl radical (.OH) formations were significantly inhibited (10-20% and 25-30%) in serum and brain mitochondria of Dasi-Ex and Fuco-I, II and III groups compared with control group. Significant differences in .OH formations of brain mitochondria in Dasi-Ex and Fuco-I groups could not be obtained, but.OH formations of brain microsomes resulted in a significant decrease (15-20%) in Fuco-II and III groups compared with control group. Basal oxygen radical (BOR) formations were significantly decreased about 10% and 13-15% in brain mitochondria of Dasi-Ex and Fuco-I group, and Fuco-II, III groups, and also decreased about 10% and 15-20% in brain microsomes of Dasi-Ex and Fuco-I groups, and Fuco-II, III groups. LPO levels of brain mitochondria and microsomes were significantly inhibited about 10% in Dasi-Ex and Fuco-I, II groups and 15% in Fuco-III groups. Oxidized proteins (>C=O) were significantly inhibited about 10% in serum of Dasi-Ex and Fuco-I, II, III groups and brain mitochondria of Dasi-Ex group, while remarkably inhibited (30~35%) in brain mitochondria of Fuco-I, II and III groups. Nitric oxide (NO) levels were significantly inhibited (12~15%) in serum of Fuco-I, II and III groups, but there no significant difference in serum NO levels of Dasi-Ex group. Superoxide dismutase (SOD) activities were remarkably increased (30~ 60%) in serum of Fuco-I, II and III groups, but there were no significant differences in SOD activities in serum of Dasi-Ex group. Catalase (CAT) activities were significantly increased about 20% in serum of Dasi-Ex and Fuco-I, II, III groups. Mn-SOD activities in brain mitochondria were significantly increased about 17% in Dasi-Ex group, while remarkably increased 26~36% in Fuco-I, II, III groups. Cu,Zn-SOD activities in brain cytosol were dose-dependently of fucoidan increased 10%, 12% and 18%, respectively, compared with control group. These results suggest that anti-aging effects of fucoidan may play a pivotal role in attenuating a various age-related changes such as chronic degenerative disease and senile dementia.

Objectives: Osteoarthritis (OA) is a chronic and degenerative joint disease characterized by progressive degeneration of articular cartilage. Inflammation is a recognized and important factor of OA progression. The present study was designed to investigate the protective effect of Corni Fructus water extract (CFW) on a monosodium iodoacetate (MIA)-induced rat model of OA. Methods: Osteoarthritis was induced by injection of MIA (50 µL; 80 mg/mL) into the knee joint cavity of rats. After an adaptation period for seven days, the rats were divided into 4 groups (n=8/group): normal, control, indomethacin-treated (5 mg/kg), and CFW-treated (200 mg/kg) groups. The rats were treated orally for 14 days. Pain was evaluated by determining hind paw weight distribution. For biochemical analyses, we measured the changes in reactive oxygen species (ROS) and peroxynitrite (ONOO^-) in the knee joint. The presence of anti-oxidant proteins and inflammatory proteins was determined by western blotting. Results: The administration of CFW significantly improved the hind paw weight distribution. The ROS and ONOO^- levels of knee joint were significantly decreased in the CFW group. CFW inhibited the production of inflammatory mediators, such as COX-2, and inflammatory cytokines, including IL-6 and IL-1β, via the NF-κB signaling pathway. The expression of anti-oxidant enzymes, such as catalase and GPx-1/2 also increased significantly. Conclusions: The findings indicate that CFW has a therapeutic and protective effect on OA by suppression of inflammation. Therefore, CFW could represent a potential and effective candidate for OA treatment.
