    초록

    Changes in total lipid content, total cholesterol content and fatty acid composition of preterm milk were investigated during early lactation. Milk samples were collected from Korean mothers of 16 premature(34 to 36 weeks gestation age) infants on day 2 to 5(colostrum) and at 6 weeks(mature) postpartum. We estimated the lipid nutrition of preterm milk by comparing with the lipids of term milk. The total lipid content of preterm colostrum was significantly lower than the lipid content of preterm mature milk(p $\omega$ 6/ $\omega$ 3 ratio of preterm milk were 2.35 in colostrum and 5.81 in mature. Therefore, colostrum in preterm milk contained higher amounts of $\omega$ 3 PUFA than mature milk. The levels of total lipid in preterm milk were higher than term milk. Also, preterm milk is richer in cholesterol, and long chain polyunsaturated fatty acid than term. It appears that the milk secreted by mothers who delivered prematurely differs from milk in several important respect. These components may serve as precursors for membrane, myelin development in the preterm infants. Therefore, it would be necessary to study further into the machanism of how the gestation age might affect to the lipid composition in human milk. These data may provide a basis for better construction of infant formaulas to provide more adequately for the lipid requirements of the Korean premature infant.

    The purpose of this study was to investigate the effect of vitamin B6 deficiency on the concentration of energy metabolite in streptozotocin-induced diabetic rats. Thirty rats were fed a vitamin B6 deficient diet(-B6) or a control diet(+B6) for 5 weeks and then subdivided into 3 groups respectively ; base group, one day diabetic group and three day diabetic group. Diabetes of rats were induced by streptozotocin injection into the tail vein. Glucose, glycogen, protein, alanine, triglyceride and free fatty acids were compared in plasma, liver skeletal muscle of rats. Also, the total urinary nitrogen and glucose excretion were compared. Compared with +B6 rats, the increase of plasma glucose in -B6 rats due to the diabetes was smaller. After diabetes was induced, the level of plasma alamine was not changed in -B6 rats while increased significantly(p

    초록

    This survey was accomplished to investigate the patterns of vitamin/mineral supplements usage in the middle-aged. Eight hundred seventy two persons of middle age were chosen from various cities and rural communities in Korea. In this study, those factors affecting vitamin/mineral supplements consumption, and usage patterns were examined. In addition, vitamin and mineral intakes through supplements were calculated, and then compared with RDA. As a result, vitamin/mineral supplements were taken by 40.8% of subjects. The higher the age, education level, family income and socioeconomic status were, the higher the percentage of supplements consumption was. City-dewellers used them more often than rural-dewellers. And vitamin/mineral supplements were taken frequently in subjects who perceived their health as poor, and concerned much about health. Illness and climacteric symptoms were also related with elevated usage. However, nutritional knowledge and food habit did not affect supplements consumption. Users mostly received information about supplements from TV/radio/newspapers, of family/friends. One of the mainly cited reasons for taking supplements, next to ' to give energy', was 'to be healthier'. The four most favored supplements, in ranking order, were vitamin B-complex, vitamin E, vitamin A and Ca. Most vitamin and mineral intakes through supplements were much greater than RDA except Ca. Especially, vitamin B1 intake was the highest as 49.6 $\pm$ 34.9 times of RDA. In conclusion, vitamin/mineral supplements used by the middle-aged in Korea was as high as those of western countries. Supplements consumption seemed to be related with affluence, poor health status, and high level of health consiousness. And supplements tended to be taken for health promotion irrespective of scientific background. Most vitamin and mineral intakes by supplements were exceeded RDA, and their intake ranges were very wide. Thus some subjects should give attention to the potential harms of megadose.

    This study was intended to investigate the anticarcinogenic effect of ginseng previously elucidated by other researches in animal studies. The sister chromatid exchange(SCE) method of human lymphocytes was used as a biomarker. Based on the literature search and the results of our laboratory, smoking was used as a parameter elevating the SCE frequency of general human population. To evaluate the smoking and ginseng effect on SCE frequency, 98 male healthy factory workers aged 23 to 58 years were divided into 4 groups : smoker with ginseng (SG), smoker control(SC), non-smoker with ginseng(NSG), and non-smoker control(NSC) groups, according to their smoking habits and ginseng intake. The mean sponteneous SCE per cell for the SG(10.8 $\pm$ 0.3) and SC(10.4 $\pm$ 0.3) groups were significantly higher than the NSG(9.1 $\pm$ 0.2) and NSC(9.3 $\pm$ 0.3) groups(p

    The concentrations of the immunological substances in breast milk and nutritional status were studied in healthy Korean women of middle socioeconomic class. The subjects were recruited at random from obstetric clinics in Seoul. The nutrients intake, prepregnancy BMI, maternal weight gain during pregnancy were studied. The concentrations of lactoferrin(LF), lysozyme(LZ), sIgA, IgG and C3 in colostrum, in transitional milk, and in mature milk, were measured. To elucidate the effect of nutritional status on immunological substances, each components was compared on the basis of either BMI, weight gain, or protein intake. The highest concentrations of the substances were found in colostrum and decreased as lactation progressed. The decline was more prominent in IgG, C3 and sIgA, and less significant in LZ and LF. The colostrum of standard weight gain group showed higher concentrations compared to lower weight gain group. This difference became smaller as the lactation progresses. BMI and nutrient intake status had less significant effect. Lower sIgA was found in lower BMI, in lower weight gain, and lower protein intake groups compared to standard groups, which indicates sIgA is the most affected substance among the measured by nutritional status.

    The weaning practice of infants from 5 to 12 months of age in the area of Chunchon, Kangwon-do was studied. Subjects were divided into 2 groups depending on residential area, monthly family income and mother's educational level. Parents of group 1 (n=90) received higher education and more monthly family income than those of group 2(n=32). The family income was significantly higher in group 1 than in group 2. Mother's educational level has been markedly improved over 10 years, which affected the feeding methods before weaning in both groups(P

    The purpose of this study was to investigate the effectiveness of enteral nutritional support to cancer patients who were clinically malnourished and receiving chemotherapy after surgery. To estimate the effect of nutritional support using Greenbia(Dr. Chung's Food Cooperation, LTD., Seoul, Korea) for patients with cancer, 41 patients were participated between January 1991 to November 1991. All patients were randomized into 2 groups and 18 patients were evaluated(experimental group : 12, control group : 6). The counseling was carried out once a week for 2 months. To compare the nutrient intake before and after administration of nutritional beverage and to identify the potential effectiveness of nutritional support in this group, a record of this diet on all patients during the test period was carried out for 3 days. To evaluate the patients nutritional status, the anthropometric parameters and serum protein were checked at the begining as baseline, week 3, week 6, and at the end of the test(week 8). In the case of energy balance, no patients appeared to be positive before administration of nutritional beverage, while 2 patients among 12 were observed to be more than 100% positive after administration. There were some differences among the experimental group which had administration of nutritional beverage but most of the results of anthropometric parameters were improved. When comparing the experimental and control group, there was significant increase in body weight, body fat, arm circumference and tricep skinfold. This study suggests that enteral nutritional support can help improving the nutritional status of patients received chemotherapy.
