232 internet sites in Yahoo and Empas were monitored to analyze what good contents of nutrition information on line have for the internet searchers. As the sites on line were disappeared frequently, all the monitored sites were selected on April 25, 2003. 3 disciplined personnels analyzed the contents of the selected sites by using self-developed monitoring format. The results are as follows. Most of sites were administered by the marketing companies and only 8% by public institutions, associations and school. Especially, most of the contents of the sites by marketing companies were advertisement about their goods instead of nutrition information. Only 42.6% of sites indicated the sources of nutrition information. Only 10.3% of site administrators responded about on-line questions quickly within 1 day. Moreover, 46% of sites were not conformed their answering periods. On the other hand, 94.8% of sites offered more than 1 feedback methods. Monitors checked purposes offering on-line informations plurally. Leading purpose was for advertising and marketing their goods(59.5%) and 47% of them were opened for offering food and nutrition information. They offered various informations at the same time. More than half of the sites had the menus for food and nutrition information and connected sites, but the other half of them only advertised their own goods. Positive sides from monitored informations were as follows : 'communicating informations easily' (8.7%) / 'definite informations for daily living' (7.2%) / 'beneficial informations for nutritional management' (4.6%) / 'new informations' (2.1%). Negative sides of offered information were 'not enough to give scientific basis and/or to simplify special evidences too much'(60.8%) / 'to exaggerate the contents' (41.4%) / 'not to indicate the notice of side effect and/or to advertise that there are not side effect from using their goods' (34.1%).

The purpose of this study was to compare convenience food purchasing behaviors and food habits. The study, which asked surveyed 131 female college students in Daejeon, in 2011, on how they used nutrition labels. The subjects were divided into two groups, in terms of the way they checked examined nutrition labels: a Check group(n=62, 47.3%) and a No check group(n=69, 52.7%). Reasons given for not reading nutrition labelings were a habit of buying for 72.2%, and too small or rude for 19.1%. The Check group reported higher interest in nutrition(p<0.001) and hygiene(p<0.01) than the No check group. Those who used the labels had higher cereal(p<0.01) and vegetable(p<0.01) consumption and a lower intake of fast foods(p<0.05). But however, most of the subjects(65.6%) chose by taste, at the time they purchased the convenience foods. The subjects considered expiry date(n=87, 66.4%) to be more important information on food labels than nutrient composition(n=11, 8.4%). The number of products whose nutrition labels were checked by over 50% was five out of 12. In conclusion, our study suggests that proper use of nutrition labeling may improve food choices and enable healthy dietary practices. Further efforts are needed to provide the public with nutrition education programs on how to read nutrition labeling. Modifying nutrition labels to make them easier for the public to understand should also be considered.

본 실험은 가공과정을 통한 올리고당의 생리적 효과가 잔존하는지를 알아보고자 하여, 설탕 대신 프락토올리고당과 이소말토올리고당을 40%수준으로 대치하여 구운 스폰지 케이크분말과 AIN-76에 준하여 만든 기본 식이를 각각 30:70으로 혼합하여 흰쥐에 25일간 섭취시켜 다음과 같은 결과를 얻었다. 실험 동물의 일일섭취량과 체중증가량 및 식이효율은 3군에서 모두 유의적인 차이를 보이지 않았다. 간의 무게와 소장 길이도 대조군과 모든 실험군에서 유의적인 차이는 없었다. 맹장 내용물과 맹장 조직량의 무게는 프락토올리고당 섭취군에서만 뚜렷이 증가하는 것으로 나타났다. 맹장 내용물의 pH는 프락토올리고당, 이소말토올리고당 섭취군 모두에서 유의적으로 감소된 결과를 보여주었다. 변내 수분함량은 프락토올리고당 섭취군에서 가장 크게 나타났으며, 이소말토올리고당군에서도 유의적으로 증가되었다. 1일 변 배설량은 프락토올리고당 섭취군과 이소말토올리고당섭취군에서 모두 증가되었다. 혈청 내 총 콜레스테롤은 프락토올리고당 섭취군에서만 유의적으로 감소하여 혈청 지질 개선 효과를 보여주었다. 혈중 요소 질소(BUN)농도는 올리고당 섭취군이 대조군에 비해 다소 낮은 경향을 보였다. 그러므로 본 연구에서 스폰지케이크 제조시에 첨가되었던 이소말토올리고당은 변배설량과 변내 수분함량의 증가, 맹장 내용물의 pH저하에 효과를 보여주었으며, 프락토올리고당은 맹장 내용물과 맹장 wall의 증가, 변 배설량 및 변내 수분함량의 증가, 맹장 내용물의 pH저하, 혈장 지질 저하 등의 효과를 보여주어 스폰지 케이크의 제조와 같은 열처리 후에도 바람직한 기능성이 충분히 남아 있는 것으로 나타났다. The aim of this study was to evaluate the effects of oligosaccharides(fructo- or isomalto-) contained in sponge cake on blood lipids and intestinal physiology in rats. The experimental diet was mixed with 30% sponge cakes. Normal male Sprague-Dawley rats weighing about 530g were randomly assigned to three groups and placed on experimental diets and deionized water at free access for 25 days. Rat in control group received a diet mixed with sponge cake containing sucrose only at 21.58g/100g diet and rats in the other two groups received diets mixed with sponge cakes of which 40% sucrose was replaced with each oligosaccharide. The results obtained were as follows: No significant differences in efficiency of food, liver weight and intestinal length were observed among groups. The cecal contents and cecal wall weights were increased more in fructooligosaccharide(FO) group than control. The pH of cecal contents decreased significantly in two oligosaccharide groups. The water contents of fresh feces in FO group were the highest and the those of two oligosaccharide groups were higher than that of control. Dry fecal weight increased significantly in isomaltooligosaccharide(IMO) group. Total serum cholesterol concentration was significantly lower in FO group. Serum triglyceride(TG) was not significantly different among three groups at p<0.05, but serum TG of FO group was lower than those of other groups. In conclusion, 40% replacement of sucrose with oligosaccharides in sponge cake may have beneficial effects on lipid metabolism and intestinal function in rats.

흰쥐의 소장 점막 세포의 성장에 미치는 Glutamine, Glycine과 Nucleosides / Nucleotide 혼합물의 효과

이선영(Sun-Yung Ly),오현인(Hyun-In Oh) 한국식품영양과학회 1997 한국식품영양과학회지 Vol.26 No.1

250g내외의 흰쥐에게 Thiry-Vella fistula를 만든 후 수술과 비경구 영양 효과로 인하여 위축되는 소장의 누공에 각각 nucleosides/nucleotide혼합용액(Nuc군)이나 glutamine(Gln군), glycine(Gly군)등을 투여하여 소장 점막의 위축 방지나 재생효과가 있는지를 알아보고자 실험하여 다음과 같은 결과를 얻었다. Thiry-Vella fistula 시술 후 9일 동안 2일에 한 번씩 총 4회 소장 누공으로 주입한 이미노산들과 nucleosides/nucleotide 혼합물의 효과는 누공의 소장 점막에 미치는 직접적인 효과와 비누공 부분에 대한 간접적인 효과로 나누어 볼 수 있다. Nucleosides/nucleotide 혼합물은 소장 누공으로 주입되어 직접 접촉되는 부분의 소장 DNA함량을 유의적으로 증가 시켰으며 단백질 함량도 높은 수치를 보여 주었고 조직 검사 결과 소장 융모의 길이와 표면적을 증가시킨 것으로 나타났다. 그러나 [³H] thymidine incorporation의 결과는 대조군과 유의적인 차이를 보이지 않았다. Glycine은 소장 단백질과 DNA에 있어서 대조군보다는 높고 Nuc군보다는 낮은 경향을 보여 주었으나 [³H]-thymidine incorporation은 누공과 비누공부분에서 모두 가장 높게 나타났으며 특히 비누공부분에서는 유의적으로 증가되어 있었다. Glutamine의 효과는 glycine 투여 효과와 비슷하거나 오히려 떨어지는 것으로 나타났다. Total parenteral nutritional effect was induced by surgical creation of Thiry-Vella fistula(TVFs) in rats. Glutamine, glycine or nucleosides/nucleotide mixture in solution was injected into the loops for 2, 4, 6, 8 days. Control animals received a 0.9% saline solution. Results include weight gain, total protein, DNA, [³H] thymidine incorporation into DNA, morphometry of the intestine in both TVFs and intestine in continuity. Perfusion of nucleosides/nucleotide mixture into the bypassed loops caused an increase in total protein, DNA content, villous height, villous surface area in loops. The injection of glycine into loops caused an increase in [³H] thymidine incorporation but the mean values of the protein and DNA contents were not significantly different from those in group Cont and group Nuc. Overall values for group Gln were slightly higher than those of the control but the differences were not statistically significant. This study suggests that this animal model may be useful for studying the effect of dietary factors on intestinal growth and maturation, separating the direct effect of diet from systemic effect on the intestine.

Food irradiation has been steadily increased in many countries concomitantly with increasing international trades. Harmful contaminants naturally occurred from foods which contain high levels of unsaturated fatty acids that are easily oxidized can affect the human anti-oxidation system through the generation of free radicals. Moreover, previous studies proved that r-irradiation may cause production of free radicals in food. We investigated the effect of r-irradiated soybeans in relation to oxidative stress in mice. Oxidative index of mice was evaluated by TBARS, DNA fragmentation in various organs such as blood lymphocytes, liver and kidney. Forty male ICR mice were equally divided into 4 groups and fed control diet or r-irradiated diet containing 50% soybeans (5, 10, and 20 kGy, respectively) for 8 weeks. Peroxide values of the irradiated diets were higher than that of the non-irradiated one and increased according to the storage period. There was no significant difference in weight gain as well as in TBARS value in plasma and kidney of all groups. Liver TBARS value of the group fed with irradiated diet at 20 kGy increased significantly compared with the control group (p<0.05). DNA oxidative damage as measured by alkaline comet assay showed that % tail DNA in the blood lymphocytes of 5 kGy and 10 kGy groups increased significantly over the control group (p<0.05). Also, tail moments of 5 kGy and 10 kGy groups were higher than that of the control group. Ultrastructural examination shows myeline figures and swollen mitochondria in parietal and intestinal epithelial cells of the group fed with irradiated diet. Therefore, considering unsaturated fatty acid content, consumption of soybeans r-irradiated with over 20 kGy or repeatedly may decrease the body's antioxidant mechanism.

Little is known about DNA-level and physiological levels for health assessments of stream or river environments. Recently, comet assay, so called Single Cell Gel Electrophoresis (SCGE) is introduced for assessments of DNA damage in the medical science, food science and mammal toxicology. The comet assay is known as a biomarker which is one of the best barometers in assessing the DNA damage by oxidative stress. In this study, we conducted the comet assay using sentinel species, Zacco platypus, as one of the pre-warning alarm systems for the aquatic ecosystem health assessments and also applied it to Gap Stream as a model system. Tail extent moments in the S1 and S2 were 5.20 and 9.90 respectively and the moment was 19.89 in the S3. Statistical ANOVA in the tail moments showed a significant difference (n=75, p<0.05) between S1 and S3. Also, the proportions of DNA in the tail were 14.47, 23.64, and $30.04{\mu}m$ in the upstream (control site), midstream, downstream sites, respectively. Our results in the downstream were accord with previous studies of individual-level, population-level, and community-level in Gap Stream. Our results suggest that the comet assay may be used as an important tool for diagnosing ecological health of aquatic ecosystems in the level of DNA.
