    This study was conducted to evaluate dietary fat intake and its effect on the plasma lipids and fatty acids composition in plasma and red blood cells(RBC) in 96 healthy Korean female college student. Three-day food intakes were recorded, and fasting blood samples were collected and analyzed for plasma total cholesterol and triglyceride. Fatty acid compositions were determined in plasma and RBC membrane. Oleic acid was the most abundant in diet, followed by palmitic and linoleic acids. Mean daily intake of cholesterol was 219 $\pm$ 127mg, mean plasma cholesterol was 160 $\pm$ 24mg/이 and mean plasma triglyceride was 68 $\pm$ 25mg/dl. Plasma fatty acids were mostly composed of linoleic, palmitic and oleic acids, while palmitic, stearic and arachidonic acids were high in RBC membrane. Plasma triglyceride showed positive correlation with BMI. Among dietary fatty acids, arachidonic acid, EPA and DHA showed negative correlation with plasma total cholesterol. Plasma triglyceride levels were negatively correlated with dietary arachidonic acid, plasma n-6 fatty acids and plasma polyunsaturated fatty acids. Dietary EPA and DHA levels were positively correlated with plasma EPA, dietary n-3/n-6 ratio were positively correlated with plasma n-3 fatty acids and n-3/n-6 ratio. Highly significant correlations were shown between the levels in plasma and RBC for several fatty acids.

    The effect of diets(high fat, high fat high energy, pectin, cellulose) on adipocyte of epididymal fat pads were investigated in 70 male rats for 8 weeks. The rats were assigned to a control(C), high fat(HF) and high fat high energy(HFHE) group for 4 wks. During the next 4 wks, reassigned to one of three treatments (high fat, pectin supplemented, cellulose supplemented) in the HF group and one of three treatment (high fat high energy, pectin, cellulose) in the HFHE group. Therefore, the total experimental groups were 7 (C, HF, HF-P, HF-C, HFHE, HFHE-P, HFHE-C). Parameters evaluated and compared for each diet were body weight, total energy intake, feed efficiency ratio and weight changes in epididymal fat pads. The results are summarized as follows ; 1) There was no significant difference in body weight gain among the groups. 2) Total energy intake was higher in the C group than other groups. 3) Feed efficiency ratio (F.E.R) of the HF and HFHE groups were greater than C group(2, 4 weeks). However, there were no significant differences between the HF and HFHE groups. 4) Epididymal fat pads(EFP 100g/B.W) of the FH and HFHE groups were higher than C group (2, 4 weeks). However, there were no significant differences between the HF and HFHE groups. There was no significant difference in weight gain of epididymal fat pads among the groups(8 weeks). 5) Cell number and cell size of epididymal fat pads of the HF and HFHE groups were higher than the C group. The pectin and the cellulose supplementation groups decreased cell number and cell size of epididymal fat pads. Especially, the pectin supplementation group decreased than the cellulose supplementation in HFHE group. Therefore, we can concluded that the HF and the HFHE diet has no effect on the epididymal fat pads.

    The effect of milk in low and high cholesterol diet was invesigated on serum cholesterol metabolism and lipid contents of serum, aorta, liver of rats. Weanling male Sprague-Dawley rats were divided into low(0.01% w/w) and high(1.01% w/w) cholesterol-diets groups. Low cholesterol groups subdivided into four groups ; control group was given water and three milk groups were given low heat milk(LM), ultra-high heat milk(HM), and powder milk(PM), respectivily, instead of water. High cholesterol groups were consisted of three groups ; control, LM, and HM groups. After feeding these experimental diets for six weeks, lipid levels were measured in serum and tissure and dried feces were analyzed for neutral and acidic sterols. Results obtained from this study are as follows : 1) Nutrient intakes, body weight gains and aorta weights did not differ among groups, but liver weights were higher in high cholesterol fed rats than low cholesterol fed rats. 2) Serum protein contents were increased independently by intakes of high cholesterol and milk. 3) Serum total cholesterol and triglyceride levels were increased but phospholipid levels and HDL-cholesterol/total-cholesterol ratios were decreased by high cholesterol in diet. And milk supplementation decreased serum total cholesterol and triglyceride levels but increased phospholipid levels and HDL-cholesterol/total-cholesterol ratios. 4) Contents of cholesterol and triglyceride in aorta and liver were elevated by dietary high cholesterol and lowered by consumption of all three types of milk. 5) Levels of cholesterol and triglyceride among serum, aorta and liver were highly correlated (r=0.7-0.9, p

    The effects of feeding diets with different fatty acids on the composition of fatty acids and vitamin E status in maternal milk & serum and pup's serum were studied. Dietary fats(10% by wt) include on oil(CO), soybean oil(SO), perilla seed oil(PO : about 60% , C18 : 3 $\omega$ 3) and fish oil(FO : rich in C20 : 5 $\omega$ 3, eicosapentaenoic acid = EPA & 22 : 6 $\omega$ 3, docosahexaenoic acid = DHA), Sprague-Dawley rats weighing 200-250g, were fed experimental diets from pregnancy through lactation period. Maternal milk was obtained by gentle squeezing after 30 minutes of oxytocin(0.2 IU, intraperitoneal) injection. The fatty acid compositions of milk and serum were analyzed at day-2 and day-15. The concentrations of vitamin E in maternal milk and serum and pup's serum were also analyzed. The groups of CO, SO and PO which had no DHA in their diet, contained DHA in their milk, The rations of EPA+DHA/arachidonic acid(AA) were higher in PO group than those in either CO or SO group. This seemed to be due not only to more conversion from C18 : 3 $\omega$ 3 to C20 : 5 $\omega$ 3 and C22 : 6 $\omega$ 3 but also to inhibition of C18 : 2 $\omega$ 6 conversion to C20 : 4 $\omega$ 6. More DHA was found in day-2 milk than in day-15 milk. It was also noted that milk contained more DHA was found in day-2 milk than in day-15 milk. It was also noted that milk contained more DHA than serum and this difference was larger in day-2 than in day-15 milk. Even though the concentrations of vitamin E both in maternal serum and milk were lower in PO and FO groups fed highly unsaturated fat than in CO or SO groups, pup's serum did not show a significant difference among all the experimental groups indicating that the pups man secure their essential nutrients by the biomagnification mechanism.

    초록

    We fed high trypotophan diet(3.5% tryptophan/diet(w/w) to mice for 7 days and treated then with 3 hour immobilization(IMMB) stress to investigate tryptophan metabolism and immunomodulation. The levels of serum tryptophan, brain tryptophan, serotonin(5HT) and 5-hydroxyindoleacetic acid(5HIAA) in the tryptophan diet fed animals were higher than those of the normal diet fed animals. Feeding tryptophan supplemented diet to stressed animal significantly decreased the levels of serum and brain tryptophan and 5HT levels. However, the amount of 5HIAA which is the metabolite of serotonin was increased in brain. Plasma corticosterone level was increased by the stress in both groups but the degree of this increase was smaller in high tryptophan fed animals. The relative numbers of CD8+ T cells, CD4+ T cells and B cells in spleen were decreased in high tryptophan diet fed and stressed animals compared to control diet fed and no stressed animals. CD8+ T cells decreased more than CD4+ T cells. The decrease of CD8+ T cells in high tryptophan fed and stressed animals was similar to that in high tryptophan fed animals or normal diet fed and stressed animals. Stress and tryptophan supplement acted synergistically to decrease the number of B cells. This study suggests that stress and tryptophan supplement could modify the number of lymphocyte cells, and indicates that the interaction of stress and tryptophan supplement on immune fuction depends on the types of immune cells.

    This study showed the psychological symptoms, nutritional status and eating behaviors of diabetic patients. General informations on subjects nutritional status were collected by questionnaire, whereas Symptom Check List-90-Revision(SCL-90R) was used for gathering the data related to psychological problem. 34 diabetics in the hospital, aged 49 $\pm$ 10.5 years old, were chosen as the subjects of this study. Their average height was 162.3 $\pm$ 9.4cm and weight was 57.0 $\pm$ 9.5kg. The average period of their suffering from DM was 54.1 weeks. Among, the subjects, 71.0% adapted diet therapy for their disease, whereas 36.7% and 40.7% did diabetic drugs and daily exercise like walking and jogging, respectively, Among 9 psychological symptoms observed, the scores of somatization, depression, anxiety, phobic anxiety and psychoticism were higher than the standard score, however they were not statistically significant. The score of paranoid ideation was lower than standard score. It was statistically significant. As the measure of their clinical status, BMI(body mass index), PIBW(percent ideal body weight) and fasting blood sugar(FBS) were selected 21.6 $\pm$ 2.8, 102.4 $\pm$ 14.8% and 207.8 $\pm$ 19.9mg/이 respectively. The somatization was significantly correlated with subjects duration of DM. Subjects with psychological problems showed wrong eating behaviors. The fasting blood sugar was significantly correlated with the level of depression.

    초록

    This study was conducted to find out the weak points of present Korean food composition table, so that to suggest the revision direction. Korean food composition table in Appendix of Recommended Dietary Allowances for Korean, 5th edition, was analyzed by comparing with 6 other food composition tables such as one other Korean food composition table, and those of Japan(two), U.S.A., East Asia and Near East. The content analysis was applied as the method of this study. As result, many drawbacks like classification of food components, etc. were pointed out. The best solution to improve these drawbacks in present food composition table is establishing on organization entirely in charge of food composition table. In this way the organization can carry out food analysis systematically and continuously. Then new food items can be added, old food items be eliminated based upon people's food consumption pattern change. Also we need to analyze our own foods consumed by our people instead of borrowing the other country's data.
