This study was an attempt to compare the energy, nutrient intake, blood lipids, and body fat distribution of diabetics with those of normal control subjects. Daily energy and nutrient intake were measured by convenient method. The following anthropometric measurements were made on all participants: weight, height, and waist and hip circumference. We matched 31 pairs with diabetics and nondiabetic control subjects by sex, age, body weight and height, and made comparisons between two groups to observe the effect of diabetes in lipid profiles. Also the effect of exercise in diabetes was investigated. The results obtained were as follows: 1. The average of daily energy intake of diabetics was 1,927 ㎉ and that of nondiabetics was 2,159 ㎉. Percentage of energy in diabetics is that carbohydrate: protein: fat = 69:13:18. 2. When diabetics were divided into obese and nonobese group according to RBW, 33% of diabetics were obese and energy intake was not significantly different between the two groups, but VLDL-cholesterol concentration was significantly higher in the obese group. 3. Energy intake, BMI, RBW and total cholesterol level of upper obesity group were significantly higher than those of lower body obesity group in male diabetic subjects. 4. When matching 31 pairs of diabetics and nondiabetics according to sex, age, body weight and height, triglyceride concentration and WHR of diabetics were measured to be significantly higher than those of nondiabetics. 5. Although energy intake was not significantly different between exercise and nonexercise groups, triglyceride, blood glucose, RBW, BMI were significantly lower in the exercise group than the nonexercise group in diabetics. 6. BMI and RBW were not correlated with cholesterol or triglyceride, but WHR correlated significantly with both cholesterol and triglyceride. In conclusion, diabetics had higher triglyceride concentration and WHR than nondiabetics. WHR may be better than BMI or RBW for predicting alteration in lipid profile and exercise seems beneficial for controlling blood glucose and lipids in diabetics.

The purpose of this study was to investigate the effect of calcium intake on lipid contents and enzyme activities in rats of different ages. Lipid levels in serum and liver and GOT, CPK and LDH activities in serum were compared in rats of different ages(4 weeks and 10 months) that were fed various levels of calcium (50, 100, 200% of requirement) for 3 weeks. Body weight gain and feed efficiency ratio were significantly higher in young rats than in adults. Serum calcium level was increased by elevation of calcium intake levels in young rats. With increasing dietary calcium levels, serum cholesterol and triglyceride levels were decreased. Liver phospholipid and triglyceride levels in the high-calcium group were significantly lower than those in other groups. Serum GOT and LDH activities of adults were significantly higher in low-calcium group than those in adequate/high-calcium groups. However, serum CPK activity of adults was significantly higher in high-calcium group than that in low/adequate-calcium groups. The results of this study suggest that adequate calcium intake may have protective effects on the alteration of lipid and enzyme activity in rats.

This study was performed to evaluate the nutrient intake status according to coffee intake among Korean female college students. Two-hundred subjects were asked for their daily coffee intake using a questionnaire. Daily intakes of nutrients and food groups were calculated 3-day food records. The mean height and weight of the subjects were 161.6㎝ and 51.2㎏. The mean daily intake of coffee and milk were 0.5 and 0.6 cups, respectively. When nutrient intake was compared to RDA for Koreans, intakes of energy, iron, vitamin A were short of recommendations. The mean intakes of calcium, sodium vitamin B₂ in BMI <20 group were significantly higher than those in BMI ≥20 group. The mean intakes of calcium and phosphorous in no-coffee group were significantly higher than those in ≥ 2 cup-coffee group. The mean intake of beverage and others significantly increased as the level of coffee intake was increased. However, intake of milk and its product decreased. There were significantly negative correlation between coffee and calcium intake, and positive correlation between milk and calcium intake. These results indicate that coffee consumption decreases calcium intake because of decrement of milk and its products. Therefore, it could be suggested that there is increased need for nutritional education on proper eating patterns for female college students.

The purpose of this study was to evaluate the nutrient and food intake status in underweight female college students living in Seoul. 126 underweight(BMI <20) and 74 normal weight(20≤ BMI<25) students were asked for their daily food intake and eating habits by using 3-day food records and questionnaire. We analyzed the amounts of the nutrient intakes and food groups as the subjects. The mean of height and weight were 162.1㎝ and 49.0㎏ in underweight and 160.6㎝and 54.9㎏ in normal weight subjects. The mean energy, iron, and vitamin A intakes among the students were smaller than RDA for Koreans. The mean calcium(p<0.01), sodium(p<0.05), and vitamin B₂(p<0.05) intakes in underweight subjects were significantly higher than those in normal weight subjects. Total food intakes of underweight and normal weight students were 1235.8g and 1078.1g, respectively. The mean of the pulse group in the underweight was significantly higher than that in normal group(p<0.01). Frequently consumed food or dish items of the subjects were Kimchi, cooked rice, and milk. In the relation between BMI and dietary factors, the BMI was found to have a significant negative correlation with calcium intake(p<0.05), pulse intake(p<0.01) and eating habit score(p<0.01). Eating habit scores about quantity of food and lipid intake showed a significant difference between underweight and normal students.

Cimetidine is a histamine H₂-receptor antagonist, used for the treatment of endoscopically or radiographically comfirmed duodenal ulcer. pathologic GI hypersecretory conditions. and active, benign and gastric ulcer. Simple method for determining cimetidine in human plasma has been developed and validated. The analytical procedure for cimetidine showed a linear relationship in the concentration ranges from 0.05 to 5 pg/ml. Coefficient of variance (CV, ° o) for intraday and interdav validation and relative error (RE. ° o) were less than ±150 o. Based on this analytical method. the bioequivalence of two cimetidine 400 mg tablets, reference (Tagamet 400 mg) and test drug (Sinil CIMETIDINE 400 mg) was evaluated according to the guidelines set by the Korea Food and Drug Administration (KFDA). Release of cimetidine from the tablets in vitro was tested using KP VIII Apparatus II with various dissolution media (pH 1.2. 4.0. 6.8 butter solutions and water). Twenty-four healthy volunteers. 21.38±1.86 years in age and 68.71±8.68 kg in bode weight, were divided into two groups and a randomized 2x2 cross-over study was performed. After oral administration of a tablet containing 400 mg of cimetidine. blood samples were taken at predetermined time intervals and concentrations of cimetidine in plasma were determined using HPLC equipped with UV detector. The dissolution profiles of the two tablet formulations were very similar at all dissolution media. In addition. pharmacokinetic parameters such as AUC, and C_(max) were calculated and ANOVA was employed for the statistical analysis of parameters. The results were revealed that the diterences in AUCf and Cma, between the two tablets were 4.17% and 0.97% respectively. At 90% confidence intervals. the differences in these parameters were also within ± 20° o. All of the above mentioned parameters have met the criteria of KFDA guidelines for bioequivalence, indicating that the test drug tablet (Sinil CIMETIDINE tablet) is bioequivalent to Tagamet 400 mg tablet.

The purpose of this study was to investigate the effect of iron and selenium intakes on utilization of manganese in rats fed adequate, 2-fold, 4-fold iron and adequate, high selenium for 6 weeks. There was no difference feed intake across iron and selenium containing diet groups. Body weight gain in 2-fold iron and high selenium group(MFeHSe) was significantly higher than those in other groups. Serum iron level was increased with iron increment, and liver iron content was decreased with selenium supplementation. Selenium and manganese contents in tissues were decreased with iron increment. In the case of manganese balance, manganese excretion through feces was significantly increased as iron intake was increased. However, retention and apparent absorption of manganese were not significantly affected by dietary iron. From these results, it could be suggested that the supplementations of iron and selenium affected the manganese utilization. Therefore, it must be considered interaction with various minerals in micro-nutrient supplementations.

There was a significant positive correlation between dietary intake and urinary excretion of iron.

음식물 쓰레기를 줄이기 위한 체계화 연구(Ⅰ) : 상용식품의 폐기율 조사와 급식소의 유형별 음식물 쓰레기량과 교육에 의한 개선효과 Survey on Waste Rates of Frequently Consumed Korean Foods and Effect of Education on Kitchen Wastes of Institutional Foodservices

전예숙,최미경 동아시아식생활학회 1999 동아시아식생활학회지 Vol.9 No.1

This research was conducted to estimate waste rates of 69 food items after pre-preparation and amounts of food wastes disposed and it's reduction effect by education in some institutional foodservices for reduction of the food wastes. The result are as follows: 1. The waste rates were 55.40% for sweet corn, 5.73% for potatoes, 19.14% for sweet potatoes, and 33.47% for chestnuts. 2. The waste rates of fruits were 0.21~49.36%. Food items with over 40% waste rate were banana, watermelon, and pineapple. 3. The waste rates of vegetables were 1.14~52.90%. The number of foods with under 10% waste rate were 14 items(red pepper, green pepper, chard, and so on), 10~20% was 9 items(perilla leaf, Chinese cabbage, ginger root, and so on), 20~30% was 5 items(root of Chinese bellflower, garlic, radish-leaves, burdock, welsh onion-large type), 30~40% was 3 items(shepherd's purse, head lettuce, kale) and over 40% was 3 items(water dropwort, crown daisy, mallow). 4. The waste rates were 24.30% in chicken, 9.53~13.79% in eggs, and 9.30~55.32% in fishes. The waste rates of vegetables and fishes were higher than those of other food groups. 5. There were significantly different in amount of food wastes disposed (g/person/day) to institutional foodservices(hospital> industrial institution> Korean restaurant> elementary school). The amount of food wastes disposed, especially amount in pre-preparation phase, after education for reduction of food wastes was significantly reduced. 6. Since these study results show significant deviations in food waste rates and education effect, there should be more studies for standard waste rates of each food and systematic education method for reduction of food wastes.
