This research aims to find the information concerning nutritional status and food intake in Korean dirt betic men. Thus, the survey was made on 202 NIDDM patients over 35 age at University Hospital. The data were analysed using F-test and mutiple comparison in SAS package program. Main results were as follows : Incidence of diabetes is high in their forties and fifties. Most of them are salary men, administrators, and professionals in middle class, who reside in metropolitan area including Seoul. They used to take light exercise and were founded NIDDM by subjective symptoms. 36.6% of them have other diseases simultaneously such as hypertension, cancer, etc. Food intake pattern prior to incidence was that intake frequency of grains, sugars, protein foods, and liking foods was higher than of processed foods. Amounts of calorie intake were shown to be lower than normal persons, so that it seemed to be controlled by doctors. In addition, the calorie ratio derived from fat was lower than RDA. Thus protein and carbohydrate ratio was relatively higher than RDA. Total moan fatty acid intake was 32.15g and it is no significance among weight groups in various fatty acid intakes. With respect to the physical standards of the diabetic men, weight, PIBW BMI, BMM, 757, arm circumference, and waist /hip ratio were higher than in normal. Therefore it seemed that these factors would be related to the diabetics. From now on, it is required to research the correlations of fatty acid intakes on the diabetes and their influence to serum lipid profiles.

The antioxidant effects of freeze-drying acorn were examined to find how much the freeze-drying acorn can reduce peroxidized corn oil poisoning, which influenced cholesterol, triglyceride, phospholipids, lipidperoxides, GOT(glutamate oxaloacetate transaminase), GPT(glutamate pyruvate transaminase) in serum, and cholesterol, triglyceride, lipidperoxides, fatty acid of phospholipids, SOD(superoxide dismutase), catalase in liver. In this experiment, male rats of Sprague-Dawley strain were used. The rats were divided into 6 groups, which were fed differently for 5 weeks : basal diet, 10% peroxidized corn oil added to basal diet, 1% acorn flour and 10% peroxidized corn oil added to basal diet, 5% acorn flour and 10% peroxidized corn oil added to basal diet, 10% acorn flour and 10% peroxidized corn oil added to basal diet, and 0.25% tannic acid and 10% peroxidized corn oil added to basal diet. The results were as follows : It was found that the peroxidized corn oil-fed 5 weeks induced the elevation of cholesterol, triglycerides, lipid peroxides, GOT, GPT in serum, and cholesterol, triglycerides, lipid peroxides in liver as compared to the basal diet-fed rats, but the acorn flour-fed rats reduced the elevation of these components. In addition, saturated fatty acid in rat liver phospholipids induced the elevation by feeding of peroxidized corn oil and, on the other hand, the acorn flour-fed rats reduced the elevation of saturated fatty acids. The acorn flour-fed rats reduced the activity of SOD in liver while they enhanced the activity of catalase in liver as compared with the peroxidized corn oil-fed rats.

The effects of the essential oil fraction and the fatty acid-fraction of the panax Ginseng on the various lipids (total cholesterol, phospholipid, triglyceride) in serum and liver tissues of the white rats were examined and observed after the administration of the fractions for eight weeks with the following results: 1. Serum total cholesterol level was slightly decreased in the group after giving the essential oil fraction four weeks, whereas the effects in the group after giving itfor eight weeks were increased. Phospholipid level was slightly elevated both in four weeks and in eight weeks, while triglyceride level was elevated after four weeks, whereas it showed nochange at all after eight weeks. In the liver tissues, the cholesterol content was slightly decreased after four weeks and remarkably decreased after the administration for eight week. Phospholipid increased after four week administration and then rather decreased after the eight week administration, while the triglyceride content decreased both in four weeks and in eight weeks. 2. In the group giving the fatty acid-fraction, serum total cholesterol level decreased after the four week administration and then returned to the pre-experiment mean after the eight-week administration, while phospholipid level increased after the four-week administration and then returned to the pre experiment mean. Triglyceride level increased after four week administration of the fraction and rather then decreased after eight weeks. In the liver tissues, total cholesterol content decreased both after four weeks and after eight weeks, while phospholipid level also decreased from four weeks through eight weeks, whereas triglyceride level increased after four weeks, and showed rather decreasing tendency after the eight-week administration.

The purpose of this study is to verify the relation between vegetarian diet and the risk factors of cardiovascular disease. To do the present study the vegetarians were selected;245 Buddhist nuns(age: 23-79yrs). For control subjects, 235 healthy female adults(age: 23-79yrs) were selected. They were the teachers, the nurses and the housekeepers living in Chinju Gyeongsang Namdoo Province. Study period was from October 1996 to February 1997. The contents are consist of survey, anthropometric measurement, and clinical examination. The average ages of the subjects were 44.20yrs for vegetarians and 40.52yrs for non-vegetarians respectively. Average body mass indice(BMI) of vegetarians and non-vegetarians were 22.47 and 21.08, WHR was 0.85 and 0.84, percentage of body fat was 28.79 and 26.55 and the average duration of vegetarian diet of the vegetarians was 13.16 years. On the nutrient related lipid, fat, the energy ratio of fat, saturated fatty acid, total fatty acid, monounsaturated fatty acid and total-cholesterol were significantly lower(p<0.01) but the ratio of p/s was significantly higher(p<0.01) in vegetarians than non-vegetarians. The vegetarians were significantly higher than the non-vegetarians in intake of fiber, vitamin C. In vegetarians, variables that significant negative correlation with fiber were total-cholesterol, AI, blood sugar. In non-vegetarians, variables that significant negative correlation with fiber were TG, total-cholesterol, blood sugar, systolic blood pressure. In both subjects, the serum lipid concentration and the blood pressure were getting lower with fiber intakes. Consequently, vegetable diet can be considerably effective in making the level of the risk factors causing in cardiovascular disease lower. (Korean J Nutrition 34(3) : 313∼321, 2001)

Objective: This study was carried out to investigate the possible application of Broussonetia papyrifera (B. papyrifera) silage as a functional feeding stuff in dairy cattle. Methods: Seventy-two Holstein cows were divided into four groups randomly and allocated to 6 pens with 3 individuals in each group and fed the original total mixed ratio (TMR) in the dairy farm or the new TMR with 5%, 10%, and 15% B. papyrifera silage, separately. Feed intake were recorded, milk and blood samples were collected, and milk composition, blood metabolites and milk fatty acids composition were measure at the end of the experiment. Results: Dry matter intake of cows decreased when they fed on diet with B. papyrifera, but no differences were observed in body condition score, milk yield, milk protein and lactose, feed efficiency and serum metabolites between groups. Both 10% or 15% of B. papyrifera silage in the diet significantly increased the immunoglobulin A (IgA) and IgG in serum, 15% of B. papyrifera silage increased the content of serum catalase, superoxide dismutase, total antioxidant capacity, and decreased the content of 8-hydroxy-2'-deoxyguanosine. Furthermore, 10% or 15% of B. papyrifera silage resulted in a significant decrease in the milk somatic cell count, and increased the polyunsaturated fatty acids content in the milk. Conclusion: The diets with 10% to 15% of B. papyrifera silage might enhance the immune and antioxidant function of dairy cows and increase the polyunstaturated fatty acid concentration in the milk.

Orotic acid의 과잉 섭취는 지질대사의 이상으로 인한 간 장해를 야기시키는 것이 알려져있다. 특히 지방간 생성에 대하여 관심을 가지게 되어서 본 연구는 orotic acid에 의한 혈청, 신장(腎臟) 및 간장(肝臟)의 지질 농도에 미치는 영향에 대하여 검토하였다. 시판 분말 chow 식이에 orotic acid 1% 첨가, 무첨가한 식이를 21일간 90g 전후의 성장기 Sprague-Dawley 계(系) 웅성 쥐에 급여하였다. 그 결과 orotic acid 1% 첨가 식이에서 혈청cholesterol, triglyceride 및 phospholipid 농도는 각각 5% 수준에서 유의하게 저하 하였다. 간장(肝臟)의 triglyceride 농도는 5% 수준에서 유의하게 저하 하였다. Orotic acid 첨가 식이에서 간장(肝臟)중량은 증가한 반면 신장(腎臟)중량은 저하하였다. Orotic acid 1% 첨가한 군에서 간장(肝臟) 및 신장(腎臟)의 phospholipid조성에의 영향은 인정되지 않았으나, 신장(腎臟)의 lysophosphatidylcholine은 높은 증가율을 보였다. 간장(肝臟) phospholipid와 비교하여 신장(腎臟)에서는 sphingomyeline phosphatidylethanolamine은 유의하게 높은 분포를 나타냈다. 신장(腎臟) phospholipid의 지방산 조성중에서 linoleic acid(18:2)가 상승하고 arachidonic acid(20:4)가 감소하였다.

This experiment was designed to evaluate the effect of various dietary vitamin $B_6$ levels on conversion from linoleic acid to arachidonic acid in various tissues in growing chicks. Growing chicks were fed the purified diet containing 7% safflower oil with different levels of vitamin $B_6$ (0, 4, 8, 40, 80 mg per kg diet) for 14 days. Feed intake and weight gain in chicks fed the vitamin $B_6$-free diet were markedly depressed. Esterified and free cholesterol concentrations in serum were significantly higher, while the serum triglyceride concentration was significantly lover in chicks fed the vitamin $B_6$-free diet compared to that fed diets with vitamin $B_6$. The liver triglyceride content was also lower in chicks fed the vitamin $B_6$-free diet. The liver and serum cholesterol ester fractions in chicks fed the vitamin $B_6$-free diet showed higher rate of $C_{18:2n6}$ and lower rates of $C_{18:3n6}$, $C_{20:3n6}$ and $C_{20:4n6}$ as compared with vitamin $B_6$ fed groups. In serum phospholipid fraction of chicks fed the vitamin $B_6$-free diet, rates of $C_{20:3n6}$ and $C_{20:4n6}$ were markedly lower. As dietary vitamin $B_6$ level was increased, the rate of $C_{20:4n6}$ was slightly increased, although it was statistically not significant. The fatty acid compositions of adipose tissue showed almost the same pattern as those in liver and serum. This result suggests that the desaturation of $C_{18:2n6}$ to $C_{18:3n6}$, elongation to $C_{20:3n6}$ or both steps might be impaired by vitamin $B_6$ deficiency in growing chicks.

Cardiovascular disease has the highest mortality rate in South Korea. Previous studies have reported that serum cholesterol level relates to intake of dietary fat and cholesterol. Therefore, in this study we developed a semiquantitative food frequency questionnaire (FFQ) for Koreans with a high-risk of hypercholesterolemia and to validate the FFQ. Semiquantitative FFQ, which includes 160 food items, reflects intakes of energy, fat, saturated fatty acid (SFA), monounsaturated fatty acid (MUPA), polyunsaturated fatty acid (PUPA) and cholesterol. We chose food items from the previous study of our research group (Suh 1999) which reported a nutritional status of Korean adults with normocholesterolemia, borderline and hypercholesterolemia. To validate the FFQ, we compared the results of the FFQ with those of a 3-day food record using a paired t-test. In addition, we calculated Pearson's and Spearmen's correlation coefficients. Intakes assessed by the FFQ and a 3-day food record were classified into quartile and the degree of agreement was obtained. Fifty-five participants responded for the validation study by completing both the FFQ and a 3-day food record. Pearson's correlation coefficients between estimated intakes by respective methods for energy, fat, SF A, MUPA, PUPA and cholesterol were 0.32,0.41,0.37,0.41,0.37 and 0.21, respectively. Spearman's correlation coefficients of energy, fat, SF A, MUPA, PUPA, cholesterol were 0.31, 0.44, 0.39, 0.46, 0.46, and 0.37, respectively. Nutrient densities in 1000kcal were compared. Pearson's correlation coefficient of cholesterol density increased and other values were similar with original values. The average degree of agreement was 67％ that intakes of energy, fat, SF A, MUPA, PUPA and cholesterol assessed by the FFQ and 3-day food records were classified within the same and the adjacent quartile. On the average, 8％ were misclassified into the extreme opposite quartile. The average of weighted kappa was 0.46. In conclusion, the FFQ developed in this study is considered to be a reliable tool to assess nutrient intakes for Koreans with a risk of hypercholesterolemia because the FFQ reflects the intakes of energy, fat, SFA, MUFA, PUPA, and cholesterol.

The dietary effects of conjugated linoleic acid (CLA) on lipid concentrations and fatty acid composition of various tissues were studied in young chicks. Chicks were fed one of four diets containing 6% tallow (TO), 4% TO-2% CLA, 2% TO-4% CLA or 6% CLA for 3wks. There were no differences in growth performances, but relative liver weight in chicks fed dietary CLA up to 4% was significantly higher than that of 6% TO group. The concentrations of various lipid fractions in serum were not affected by CLA feeding. With the increase in dietary CLA levels, total CLA in liver and leg muscle increased linearly.
