Purpose: The purpose of this study was to examine the effects of daily exercise before steroid treatment on mass, the type I and II fiber cross-sectional area, and myofibrillar protein content of hindlimb muscles in a rat model. Method: Adult male Sprague-Dawley rats were randomly assigned to one of three groups: a control group(n=10) that had a normal saline injection for 7days, a steroid group(n=10) that had a steroid injection for 7days, and an exercise-steroid group(n=10) that ran on the treadmill for 7days before a steroid treatment. Body weight and food intake were measured every day. At 15 days all rats were anesthetized and the soleus, plantaris and gastrocnemius muscles were dissected. Result: The exercise-steroid group showed significant increases as compared with the steroid group in body weight, muscle weight of the soleus and gastrocnemius, type II muscle fiber cross-sectional area of plantaris, and myofibrillar protein content of the soleus, plantaris, and gastrocnemius. As compared with the control group, the steroid group showed significant decreases in body weight and diet intake, muscle weight, the type II fiber cross-sectional area and myofibrillar protein content of the soleus, plantaris, and gastrocnemius muscles. Conclusion: Daily exercise before steroid treatment attenuates hindlimb muscle atrophy, with type II muscle changes more apparent than type I muscle changes.

This study was carried out to investigate the dietary behaviors and nutrient intake of high school girls in Iksan and Seoul cities. The subjects consisted of 122 students in Iksan city, and 136 students in Seoul city. The proportion of subjects who eat meals irregularly was higher in Iksan ($94.8\%$) than in Seoul ($80.9\%$). The proportion of subjects who skip meals was also higher in Iksan ($61.5\%$) than in Seoul ($56.6\%$), and most of them ($69.7\%$) skipped breakfast, even thought they thought that it was the most important meal ($86.4\%$). The subjects tended to overeat at lunch ($41.9\%$) and dinner ($55.4\%$). The main reasons that the subjects skipped a meal were a lack of time (50.7%) and poor appetites ($23.7\%$). Most of the subjects ($57.4\%$) had tried to control their body weight by taking drugs ($40.5\%$), doing exercise ($34.5\%$), and controlling their diet ($25\%$). The average intake of nutrients and energy was significantly higher (P<0.05, p<0.01) in Iksan than in Seoul. The intake was below the RDA recommendations except for phosphorus in I ksan, but was above it except for calcium, iron, and vitamin B2, in Seoul. The indexes of nutritional quality (INQ) of calcium (0.5), iron (0.6), vitamin A (0.8), vitamin B2 (0.7), niacin (0.9), and vitamin C (0.9) were under 1.0 but those of protein (1.0), phosphorus (1.2) and thiamin (1.0) were over 1.0. The INQ of the other nutrients, except protein and vitamin C, was significantly higher in Seoul than in Iksan.

A long life is the desire of many people. The purpose of this study was to describe long life factors for people aged one hundred and above on Chju island. The research was conducted using a phenomenological method to add understanding to this subject. The field work for this study was done from July, 1997 to February, 1998 on Cheju island. The sample consisted of 10 persons of one hundred or above and 12 families. They were audio-recorded and analyzed using Colaizzi's (1978) method. The results of the present study shows the following: The thoughts of the persons one hundred and above showed ten important concepts; 'dietary regimen', 'mental regimen', 'sleep regimen', 'residence regimen', 'health regimen', 'labor regimen', 'exercise regimen', 'being born', 'filial piety and posterity', 'attachment to life'. Concerning 'Dietary Regimen': Dietary regulation, Preferential food intake, Living on vegetables, Light eating, and concern for longevity in food intake were important. Concerning 'Mental Regimen' : Harmony, Clearheadedness, Mildness, Abstinence, Generosity, Relaxation, Gaiety, Inspiration and Strength were important. Concerning 'Sleep Regimen'; Enough sleeping hours, Sound sleep, Curved sleeping posture, and Comfortable bedding were important. Concerning 'Residence Regimen' ; Clean dwelling, Pleasant surroundings, Thatched house life, Living in the village with good-hearted people, and Regular life were important. Concerning 'Health Regimen'; Temperance of drug, use Proper temperature, Proper humidity, and a Clean body were important. Concerning 'Labor Regimen'; Agricultural labor, Diligence, and Domestic labor were important. Concerning Exercise Regimen': Proper exercise, and Sunbathing were important. Concerning 'Being Born' ; Strong physical constitution, Longevity lineage, and Destiny were important. Concerning 'Filial Piety and Posterity' : Showing respect to a long-lived elder and Reducing anxiety were important. Concerning 'Attachment to Life' ; The desire to live long was important. The following conclusion was made from the above results. Human beings cannot avoid death, but the span of life can be prolonged to the maximum span of human life by wisdom, health care, and proper environmental conditions. As a result, a health regimen must be imposed for longevity such as controling food intake, having positive thoughts, being relaxed, sleeping enough, clean dwelling, taking care of oneself which can improve immunity and resistance to decrease, as well as proper labor and exercise. In addition, when filial piety is served, the desire of longevity and retaining one's youthfulness for a long time can be achieved. These should be done to live long and lead a qualitative life. By the results of this research, the following is suggesed for nursing. To satisfy the basic nursing principle that nursing must be practiced to help people live long, education must be spread to people who are nursed and their family so that they can lead a healthy life. And in nursing elders, nurses must recognize that elders have a strong desire for life, even though they may have negative thoughts about life at times. Therefore nurses have to respect the elders' value of life, and help them improve their self-esteem and self -fulfilment.

Purpose: The purpose of this study was to investigate the relationship between dietary flavonoids intake and metabolic syndrome (MetS) in Korean women with polycystic ovary syndrome (PCOS). Methods: A total of 223 subjects (mean age; $27.3{\pm}4.2$ yrs, range; 17-38 yrs) were divided into the MetS group (n = 27) and non-MetS group (n = 196). Dietary intake data were assessed by 24-hour recall method for two non-consecutive days and the average of the two days was used to estimate the usual dietary intake. Dietary habits were assessed using the Mini Dietary Assessment (MDA) score. We analyzed the intakes of six flavonoid classes (anthocyanidins, flavan-3-ols, flavanones, flavones, flavonols, and iso-flavones) using a flavonoids database. Results: After adjustment for age, total energy intake, alcohol consumption, smoking, regular exercise, and oral contraceptive use, dietary flavonols intake was significantly lower in the MetS group ($5.1{\pm}2.4$ mg/d) than in the non-MetS group ($8.9{\pm}2.8$ mg/d) (p = 0.0472). Intakes of other flavonoids except for flavonols did not differ between the two groups. In MDA scores, significant differences were observed only for that related to daily consumption of fruit or fruit juice (p = 0.0180). A significant inverse relationship was observed between flavonols intake and the risk of MetS (4th vs. 1st quartile, OR = 0.11, 95% CI = 0.02-0.62, p for trend = 0.0131). Conclusion: These results suggest that higher intake of flavonols may be beneficial for MetS in PCOS women.

The purpose of this study was to investigate the eating patterns, nutrient intakes, blood levels, and health status of male college students in Seoul according to body mass index (BMI). In this study, we classified subjects into normal weight (n=240), under weight (n=11), and obese (n=46) groups according to BMI. The weight and BMI were significantly higher in the obese group compared to other groups (p<0.0001). The obesity was associated with overeating and frequent eating. The under weight group showed significantly higher consumption of fast food, snacks, and fried foods compared to the other groups (p<0.05). The intakes of milk, meat, fish, eggs, and fried food and preference ratios were higher in the obese group (p<0.05). The male college students in this study showed insufficient intakes of calories, vitamin C, folic acid, and calcium. The plasma LDL-cholesterol levels in the obese group were higher compared to the other groups. In conclusion, intake of nutrients among male college students is found to be insufficient and requires nutritional education. The under weight group showed regular eating habits and increased nutrient intake. The obese group was shown to need more exercise with higher intakes of vegetables and fruits.

The study aimed to identify major factors related to global self-rated health of the community-dwelling elderly people in rural areas. Interviews were conducted with 433 persons over 65 years of age. The socio-economic characteristics, chronic disease status, measures of functional and mental health, life satisfaction, health-related behaviors including smoking, drinking, exercise, social activity, dietary habit, and food intakes were analyzed to determine their influence on self-rated health index. Data on food intake were obtained through the 24-hour recall method. The self-rated health of rural elderly was poor or very poor as reported by 42.6% and 52.4% of the men and women, respectively. Poor self-rated health was found to be related to elderly aged $65{\sim}74$, female, absence of work, more chronic diseases, dependence on Instrumental Activity Daily Living (IADL), higher mental unhealthy days, lower current life satisfaction, less social activity, lower dietary habit scores, lower intake of total food, fruit, eggs, fishes & shell fishes, vitamin C (%RDA), and Nutrient Adequacy Ratio (NAR). The results of the multiple regression analysis showed that poor self-rated health index is significantly associated with more chronic diseases, mental unhealthy days, gastrointestinal disease, musculoskeletal disease, less social activity, and lower intake of fruits. The results also suggested that improving the nutritional status and functional ability, and reducing the burden of chronic diseases are beneficial to the self-rated health index of the elderly.

The present study was carried out to evaluate the physiological effects of mushroom supplementation on blood glucose levels, lipid profile, and antioxidant enzyme activities in subjects with type 2 diabetes mellitus. Subjects were randomized into either a control group or mushroom supplementation group. Mushroom supplementation was provided 3 times a day for 4 weeks. We found that total dietary fiber intake was about 2.5 times higher (30.3 g vs. 12.3 g) in subjects receiving mushroom supplementation than in the control group. Two groups maintained the same food intake and amount of activity, exercise during the supplementation. We observed no difference in age, height, weight, BMI (body mass index), blood pressure between the groups. Nutrient intake did not differ appreciably between the two groups, except for fiber intake, during the supplementation. Fasting blood glucose levels and 2-hour postprandial blood glucose levels were significantly lower in those ingesting mushroom than in controls. Furthermore, the concentrations of low-density lipoprotein cholesterol were decreased significantly in the mushroom supplementation group. Small changes were observed in the concentration of total cholesterol, triglyceride, high-density lipoprotein cholesterol of those supplemented with mushroom, but these changes were not statistically significant. Activities of superoxide dismutase and catalase with mushroom supplementation were higher than in controls, but and glutathione peroxidase activity was not affected. The levels of thiobarbituric acid reactive substance of mushroom group were lower than control group, but were not significant. We conclude that addition of mushroom influences glycemic control and may be effective in lowering blood lipids and improving antioxidant enzyme activities. Accordingly, such effects may reduce risk factors for cardiovascular disease in patients with type 2 diabetes. However, to confirm these effects and to make dietary recommendations for patients with type 2 diabetes, further studies are necessary.

This study was conducted to investigate the dietary behaviors and health-related lifestyles, according to exercise habits, of female university students in the Jeonju area. Self-administered questionnaires were collected from 285 students, and the statistical data analysis was completed using the SPSS v. 10.0 program. The results are summarized as follows. The weight, height, and BMI averages of the regular exercise and non-exercise groups were 53.05 kg, 162.46 cm, and 20.23, and 50.81 kg, 161.46 cm, and 19.48, respectively. The breakfast skipping ratio was higher in the non-exercise group than the exercise group. More than 72% of the exercise and 71% of the non-exercise group responded to regularly having lunch at the university canteens or restaurants around campus. Approximately 70% of the exercise and 71% of the non-exercise group responded to having dinner irregularly, which was mainly caused by reasons such as 'irregularity of life style' and 'appointments with friends'. The snack intake ratios of the exercise and non-exercise groups were high, but the exercise group ate more fruit, yogurt, and milk than the non-exercise group. The favorite sports of the exercise group were 'walk(jogging)', 'yoga', 'bicycle,' 'swim,' etc. In particular, 5.3% of the exercise group had ridden a bicycle to the university. More than 97% of the students were non-smokers. About 14% of the exercise and 15% of the non-exercise group rank alcohol once or twice a week. The exercise group did not show exceptional health-oriented dietary behaviors in comparison to the non-exorcise group. Therefore, an exercise-oriented nutrition education program would be beneficial to the students, in order to improve their dietary behaviors and health-related lifestyles.

A 42-year old male patient was referred to the Department of Oral Medicine, Kyungpook National University Hospital due to the chief complaint of limite mouth opening. Three years ago, the patient was diagnosed as an infarction of both cerefellar hemispheres, acute obstructive hydrocephalus and acute epidural hematoma of frontal lobe at the department of neurosurgery.Both of the infarcted cerevellar hemispheres and the epidural hematoma of frontal lobe were removed with suboccipital and frontal craniectomu. After the brain surgery jaw opening range was decreased progressively and ultimately mouth opening became almost impossible. Spasmodic and rhythmic contractions of the masseter muscles occurred intermittently during daytime as well as sleeping. Food intake was available only through Levin -tube. Actibe jaw opening exercise was prescribed with the aids of tongue blades. A moist hot pack and indomethacin phonophesis were also applied 20 minutes three times a day to decrease discomfort muscle activities. After a month of treatments, the opening range was increased to 5mm at the premolar area and oral food intake was possibel. The L-tube was removed and the patient was discharged.

This study was intended to investigate food, exercise habits, perception of health status and the effects of nutrient intake of female college students. Food habits such as regularity of meal time, repast of breakfast, numbers of night snack per week and duration of meal were assessed via a self reporting questionnaire, and 24hrs recall method for nutrient intake was obtained from 155 female college students in Yangju-si. The mean height and weight of the subjects were $161.25{\pm}3.52cm$ and $52.26{\pm}4.52kg$, respectively. The average intakes of energy and nutrients were below the Korea recommended dietary allowance(RDA). Especially, The nutrient intakes(energy, protein, fat, fiber, calcium, iron, phosphorus, zinc, sodium, potassium, vitamin B6, niacin, vitamin C, folate, vitamin E, cholesterol) of the group in which the regularity of meal time per week was 5~7 days was significantly higher than the group in which the regularity of meal time was < 3 days (p<0.005). The nutrient intakes influenced by the food habit such as the regularity of meal time, skipping breakfast, and the numbers of night snack per week but did not differ in accordance with the regular exercise habits and perception of health status. These findings suggest that nutritional education based on female college students' food habits(regularity of meal time, skipping breakfast and night snacks per week, and duration of meal) may be required to improve dietary variety. It is considered that the improvement in dietary habits will contribute to the improvement of nutrition.
