Application of RDA bibliographic data in library cataloguing / 中华医学图书情报杂志

The new cataloguing rules, RDA, have been implemented in NLM and more RDA bibliographic data can thus be accessed in domestic medical libraries when the Western documents are catalogued by offloading their bibliographic data.The differences in RDA and AACR2 were compared, the common modified fields and descrip-tive contents were described when the RDA bibliographic data were changed into AACR2 bibliographic data in order to provide certain reference for cataloguing of Western documents using the RDA bibliographic data.

An Interesting Case of Disappearing Murmur

Cardiovascular manifestations in a patient with congestive heart failure, which disappeared in short course of time, ignited the idea to think of unusuality from common rheumatic heart disease (RHD). Cardiac events that reversed within 2 days of admission in a chronic alcoholic, whose diagnosis puzzled us, are presented here. A retrospective conclusion of wet beri-beri is made, as all the haemodynamic sequelae vanished with thiamine replacement.

Introduction: Vitamins are nutrients that have multiple benefits for our body which are used to enrich foods to increase nutritional intake. Objective: To determine whether the intake of fortified foods exceeded dietary recommendations (RDA) and tolerable upper intake level (UL). Methods: 213 fortified foods on the market were identified. An alimentary survey was performed using a photographic set of298foods in high school males and females students from Metropolitan Region. The intake of nutrients was calculated and the fortified vitamins on foods were added. Results: Men exceeded recommended intake for all vitamins, whereas women have a deficit in B12 Vitamin. Vitamins whose intake exceeds the UL are, folate, 27.5%, B3 vitamin 16.4%, A vitamin 7.8% and B6 vitamin 1.6%. Conclusion: All tested vitamins exceeded recommendations except for B1vitamins in women; folate; B3, B6 and A vitamin exceed the UL.

Nutritional Evaluation of Served Menu in Korean Temples

This study was performed to evaluate served menu in Korean temples. Among available temples in the nation, 34 tem-ples were carefully selected considering location and the gender characteristics. A five consecutive day menu was collected to analyse by interview between Jan 2004 and Aug 2004. Mean energy content of menu was 1633.8 kcal, with 67.3% of energy supplied by carbohydrate, 14.8% by protein and 17.9% by fat. Beans and bean products were the major contribu-ting dishes for most nutrients. Contents of most nutrients except energy, protein and vitamin B were higher than RDA. Nutrient adequacy ratio (NAR )were 0.9-1.0 and mean adequacy ratio (MAR )was 0.9 for temples. Total number of dishes from menu was 7.3. Dietary variety score (DVS )was 26.4 and buddhist monk temples offered more diverse foods than buddhist nun temples. KDQI (Korean diet Quality Index ), overall diet quality index were 0.67 and those of bud-dhist nun temples were better than those of buddhist monk temples. From the result of this study it was concluded that the temple diet is nutritionally well balanced, rich in dietary fiber and low in cholesterol. So it can be a healthy diet for the mo-dern person. This is the very first study attempting the nationwide investigation of temple diet in Korea. It will be used as fundamental data to improve quality of diet to prevent modern chronic disease.

Micronutrientes envolvidos no crescimento / Micronutrients involved in growth

Os hábitos alimentares infantis têm sofrido modificações drásticas nas ultimas décadas. A aversão a frutas, verduras, carnes e laticínios, juntamente à predileção por produtos artificiais e industrializados observada entre crianças, tem despertado preocupação entre os profissionais da saúde. Isso porque estudos têm demonstrado a influência negativa do consumo insuficiente de alguns nutrientes no crescimento e desenvolvimento infantil. Cientes deste problema, desenvolvemos este artigo visando esclarecer algumas dúvidas quanto a função e importância de alguns micronutrientes como o zinco, ferro, vitamina A, ácido fólico, cálcio e vitamina D, bem como suas recomendações nutricionais, como auxilio a elaboração de tratamento e estratégias nutricionais que poderão garantir o crescimento e desenvolvimento normais entre as crianças

The infant habits have suffered drastic alterations in the last decades. The avoidance of fruits, vegetables, meat and milk products, with the preference to artificial and industrialized products observed among children have raised concerned among the health working groups. This is due to the studies that have demonstrated the negative influence of insufficient intake of some nutrients on infant growth and developing. Considering this problem, we wrote this article to clarify some doubts about the functions and importance of some micronutrients such as zinc, iron, vitamin A, folic acid, calcium and vitamin D, as well as nutritional recommendations, as a contribution to the elaboration of treatment and nutritional strategies that would ensure children growth and development

Isolation of ethanol-induced genes in pancreatic beta-cells by representational difference analysis (RDA)

Recent epidemiological studies suggest that alcohol consumption is one of the risk factors leading to type 2 diabetes, but the direct effect of ethanol on beta-cell gene expression is not known. Here, using cDNA RDA method, we isolated 43 ethanol-induced genes in pancreatic beta-cells, and confirmed their differential expression by Northern blot or semi-quantitative RT-PCR. These genes were further categorized by the functional criteria based on the published data; Translation, Transcription, Metabolism, Signal transduction, Transport, Structure, Cytoskeleton, Regulation, or Putative/Unknown genes. The effects of each gene on beta-cell function need to be further investigated, however, the present data strongly suggest that these genes might be related to the metabolic alterations caused by ethanol as indicated in earlier study. In particular, RPS3 gene expression was increased by ethanol, glucosamine, and cytokines, implying that ethanol might decrease the metabolic activity by oxidative stress in beta-cells. Therefore, cloning of these genes in full-length and the detailed studies of each gene on beta-cell functions might provide clues on the pathophysiology of type 2 diabetes caused by alcohol.

Evaluation of Nutrient Intake Quality Over 40 Year-Old People Living in Rural and Suburban Areas / 대한지역사회영양학회지

ABSTRACT To assess the quality of nutrient intake by area of Korean adults, a dietary survey with the 3-day record method was obtained from 324 subjects aged 40 years and older but younger than 70 (52.4 +/- 8.7) living in a rural area (Ansung) and suburban area of a middle-sized city (Ansan). The quality of nutrient intake was assessed by analyzing Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR) and Index of Nutritional Quality (INQ). The average daily mean energy intakes were 1,832 kcal for Ansung and 1,842 kcal for Ansan, respectively. Daily intakes of fat for Ansung and Ansan subjects were 40.9 and 40.3 g, and those for protein were 75.1 and 73.1 g, respectively. The overall calorie: protein: fat ratio (CPF) of energy intake was 63 : 17 : 20. Daily mean intakes of protein, fat, calcium, phosphorus, iron, potassium, carotene, sodium, thiamin, and niacin were significantly higher in Ansung residents than in Ansan subjects (p< .05). The average intakes of energy, calcium, vitamin A were lower than Recommend Dietary Allowance (RDA) in both areas. Note, over 30% of the study subjects had less than 75% of RDA of calcium, vitamin A and riboflavin. The MAR was higher in Ansung than Ansan residents (0.86 and 0.85, respectively; p< .05). INQs were over 1 for most nutrients except calcium (0.87), and that of calcium and phosphorus was each significantly higher in Ansung than Ansan subjects. Based on these results, nutrient intake quality of subjects aged 40 to 69 years living in the surveyed rural area is comparable to that of semi-industrialized suburban area in Korea. Dietary deficiency in all of calcium, vitamin A, and riboflavin, however, was a common problem for both rural and suburban residents.

A Survey of Food and Nutrient Intakes of Korean Men by Age Groups

A dietary survey was conducted using 24-hour recall method in 80 male elementary school children, 83 high school students, 87 adults and 98 elderly people over 65 years of age to discuss food and nutrient intakes among different age groups. In observing food intake by age groups, the percentage of plant foods to total food intake was significantly higher in the elderly than other groups and that of animal foods was the highest in the children. The children consumed significantly higher amounts of milk and dairy products. Carbohydrate energy percent in the elderly people was 68.0%, significantly higher than other age groups. All age groups consumed Ca below Korean RDA and especially, 65.1% of the adolescents and 68.4% of the elderly consumed below 75% of RDA. Nutrient adequacy ratio (NAR) of most nutrients was lowest in the elderly. Mean adequacy ratio (MAR), an index of overall dietary quality, was 0.94 for the children, 0.84 for the adolescents, 0.84 for the adults, and 0.73 for the elderly. The above results suggest that food and nutrient intakes have been differently affected with advancing age, and overall dietary quality of the elderly people is lower than that of other age groups.

Recommended Dietary Allowances for Young Children and Food Guideline for Preschool Children in Sweden / 대한지역사회영양학회지

The purpose of this study is to offer information related to recommended dietary allowances for young children and food guidelines for preschool children in Sweden. Sweden, located in Europe, is the most developed country for young child care system. Swedish nutrition policy background, Swedish recommended dietary allowances for young children, and food guidelines of early childhood education center in Sweden were used. The number of Swedish child care centers increased from 70,000 in 1970 to 700,000 in 2000. The Swedish Institute of Public Health promoted children's indoor and outdoor activity. The aim of the Swedish public health contains children's safety, good food habits, and eating food safely. Swedish Food Administration made recommended dietary allowance and food guidelines for children care centers. The aim of food guidelines was to increase energy, calcium, iron, and dietary fiber intake. Swedish RDA contains minimum and maximum intake as well as mean intake for macro and micro nutrients. The fat intake ratio of energy is increased for younger children. For preschool children, the food guideline is determined by dietary allowances for breakfast, lunch, and snack respectively. Food guideline contains meal time schedule, menu for each meal using food model, amount of food for age group, and recommended dietary allowance for each meal. It is recommended for Korean early childhood education center: 1) Korean RDA for young children should be made range of intake, minimum and maximum intake. 2) Food guideline should be make for Korean child care center. 3) Korean child care centers should offer an afternoon snack twice for children who retun home late. 4) Nutrition education program for preschool teachers should be developed for children's good eating habits and health promotion.

A Study of Dietary Behavior and Serum Leptin Levels of Obese Children / 대한지역사회영양학회지

The purpose of this study was to investigate the relationship among serum leptin, nutritional status, and the obesity indices of 55 obese children in Daegu and Kyungpook area. Obesity was defined as fat percentage that exceed 25% of body fat mass. Energy and nutritional status were tended to be low, and dietary intake of calcium and iron were less than any other nutrients in all the subjects. Especially, beverage intake of obese group was more than non-obese group. The leptin level were significantly correlated with %RDA of energy (0.41, p < 0.001), protein (0.44, p < 0.001), phosphate (0.40, p < 0.001), iron (0.37, p < 0.001), vitamin A (0.31, p < 0.01), thiamin (0.40, p < 0.001), riboflavin (0.26, p < 0.05), niacin (0.51, p < 0.001), and vitamin C (0.24, p < 0.05). The leptin level were significantly correlated with MAR (mean adequacy ratio, r = 0.43, p < 0.001) and INQ (index of nutrient quality) of thiamin (r = 0.22, p < 0.05). Multiple regression analysis showed that %RDA of niacin in obese group (R2 = 0.208, p = 0.001) and total subjects (R2 = 0.257, p = 0.000), MAR (p = 0.003) and INQ (p = 0.048) of niacin in obese group (R2 = 0.255) and MAR (p = 0.000) and INQ of Ca (p = 0.024) in total subjects (R2 = 0.231) may be important independent predictors to leptin level. MAR showed a significantly positive correlation with %fat (r = 0.42, p < 0.01), BMI (r = 0.46, p < 0.01), RW (r = 0.44, p < 0.01), WHR (r = 0.39, p < 0.01) and, %RDA (p < 0.05, p < 0.01). These data indicated relationships among leptin level, nutrient intake, %RDA, MAR, and INQ in children.

A Survey of Food and Nutrient Intakes of Korean Women by Age Groups

To study the level of change in food and nutrient intake among different age groups, a dietary survey using the 24-hour recall method was conducted among 80 female elementary school children, 84 high school students, 100 adults from 25 to 35 years old and 120 elderly people over 60 years of age. The results of the study showed that plant food and total food intake were higher in adults and animal food intake was significantly higher in children. The percentage of plant food to total food intake was highest in the elderly and that of animal food to total food intake was highest in the children. The elderly consumed significantly less meat and poultry and more fish than the other groups. However, the children consumed significantly higher amounts of milk and dairy products. The elderly had the lowest Ca intake. Carbohydrate energy intake in the elderly was 70.3%, significantly higher than that for the other age groups. All of the age groups consumed a quantity of Ca below the Korean RDA and 77.5% of the elderly consumed an amount below 75% of the RDA. Nutrient adequacy ratio (NAR) of most nutrients was lowest in the elderly. Mean adequacy ratio (MAR), an index of overall dietary quality, was 0.88 for the children, 0.84 for the adolescents, 0.80 for the adults, and 0.70 for the elderly. Therefore, the results show that food and nutrient intake changes with advancing age, and the overall quality of the diet of elderly people is lower than that for the other age groups.

Macronutrient, Mineral and Vitamin Intakes in Elderly People in Rural Area of North Kyungpook Province in South Korea

Poor dietary habits and inadequate nutrient intakes are of concern in the elderly, even it is worse in rural areas. In the present study, we conducted the anthropometric measurement and the dietary intakes including macronutrients, minerals and vitamins to assess the nutrient intakes and nutritional risk in elderly people in rural kyungpook province in South Korea. Subjects (n = 168, mean age, 67.3 yrs) were interviewed using d general questionnaire and 3 days of 24-hours recall for dietary intake. Nutrient intakes were analyzed using CAN-pro soft program and compared to Korean RDA and nutrition reference values (NRV). The anthropometric measurement showed that the weight and the height of the subjects in the rural area were below the average of the same age of Korean elderly people. The energy and protein intakes were 85% and 90% of Korean RDA, respectively. The intakes of lipid, cholesterol and dietary fiber were 62%, 40% and 22% of NRV for Korean adults. Main sources for protein and lipid intakes came from the vegetable sources and this pattern was more prominent in female elderly people. Ca intake was half of Korean RDA (56%), while P intake was 132% of Korean RDA. For the antioxidant trace mineral (Fe, Cu, Mn, Zn, and Se) intakes, Fe and Zn intakes were 78% and > 103% of Korean RDA. Cu, Mn and Se intakes were > 113%, > 275%, and > 185% of Korean NRV. Thiamin, niacin and vitamin C intakes were above Korean RDA, but the intakes of vitamin A and riboflavin were 88% and 63% of Korean RDA, respectively. On summarizing the results of the present study, the elderly people in rural area consume less lipid, cholesterol, Ca, and dietary fiber. Ca intake is lower, while P intake is higher, and this would be the potential risk for bone health. Also, Na intake was high, which can be the potential risk for the cardiovascular disease prevailance. Vitamin intakes were fairly good status, excepting riboflavin. Antioxidant mineral intakes were much higher than Korean NRV, unexpectedly. The results suggest that the elderly people in rural area have inadequate intakes of protein, lipid, dietary fiber and Ca, which mainly should be supplied from animal products. Recommendations to increase diet variety would be emphasized for this nutritionally poor-conditioned subjects, specially including animal food products and high dietary fiber food.

ISOLATION OF FEMALE－ SPECIFIC SEQUENCE OF SCHISTOSOMA JAPONICUM / 中国人兽共患病学报

Aim To isolate the female-specific sequence of Schistosomajaponicum S. J. in order to provide a basis for researching vaccines of anti-fecundity. Methods Representational difference analysis (RDA) was used to obtain a female-specific sequence of S.j. by the male S.j. genomic DNA substractive hybridization with the female. The fragment was about 562bp. Results This sequence was labeled as Dig probe by PCR technique to hybridize with the restriction fragments of each sex and the tester as well as the driver on the nylon membranes.The antiboly of Dig、 NBT、 and X-phosphate solution were utilized to immunoassay the result of hybridization. The result showed that the probe can hybridize to the tester but can not hybridize to the driver. Conclusion The result suggested that the fragment of approx. 562bp was the female-specific sequence of Schistosoma japonicum.

Relationship between the Number of Different Food Consumed and Nutrient Intakes / 대한지역사회영양학회지

In order to examine the relationship between the number of different foods consumed and nutrient intake, one-day food consumption were surveyed by 24-hour recall from a sample of 287 individuals(20-49 years) living in Daejon City. The number of consumed food items did not include seasonings except red pepper power, sugar, oil, and soybean paste when used in large amounts(DVS). The number, including all seasonings except salt and vinegar(DVSS), was also counted. Of the total subjects, 43.6%(DVS) or 39.0%(DVSS) consumed 18-23 daily different foods with an average of 20.2 or 22.9, respectively. As the DVS increased, daily intakes of total foods and most food groups were elevated. Cereals however were not changed and eggs were decreased with increasing DVS. Energy and nutrient intakes and their mean adequacy ratio(MAR) and index of nutritional quality(INQ) also show positive correlations with DVS. MAR equal to or greater than(> or =) 0.75 was taken as a cut-off point for nutritional adequacy. In that case, the mean INQ was shown to be > or =1. MRI(10) for energy and 9 nutrients and MAR(3) for Ca, vitamin A, and riboflavin were estimated. Form a regression analysis, when MAR(10) was 0.75, the DVS and DVSS were assumed to be 19.6 and 22.2, respectively. And when MAR(3) was 0.75, the DVS and DVSS were assumed to be 31.6 and 34.6, respectively. However the subjects whose MAR(3) was 0.75(0.7-0.8) 23.8(DVS) or 26.6(DVSS) different foods in average, and their mean intakes of energy and all nutrients, except vitamin A, were ranged at 85-100% of the RDA. Of the 74 subjects who consumed DVS> or =24, 24 to 42 numbers took or =32 took > or =125%RDA of protein, which showed concerns of overnutrition in case of DVS> or =32. Form the above results it could be suggested that a daily intake of 24-32(or 28) of DVS or 27-35(or 31) of DVSS was recommendable for an optimal nutritional of all nutrients if the variety of food groups and sufficient intake of vitamin A and calcium were emphasized together.

A Longitudinal Study of Calcium and Phosphorus Intakes of Korean Infants from 1 to 3 Months in Breast-Fed vs Formula-Fed Infants / 대한지역사회영양학회지

This study was carried out to evaluate the calcium and phosphorus intakes and correlation with growth performance of 25male breast and formula-fed infants from 1 to 3 months postpartum. There were four groups breast-fed(BF) and three formula-fed groups(FFM, FFN and FFP). There was no significant difference in the height and weight of infants according to feeding methods and formula brands. Milk intake and the concentration of calcium and phosphorus from human milk and the formulas were measured. The average calcium content of human milk was 26.6+/-4.1mg/dl and 13.5+/-2.0mg/dl, respectively. The average calcium intakes of the brest-fed and formula-fed infants were 205.5+/-29.3mg/day and the 460.5+/-70.6mg/day, respectively the average calcium intake of breast-fed infants was significantly lower than that of formula fed infant. The percent of RDA(41%) of breast-fed infants was lower than that(75.4%) of formula fed infant. The average phosphorus intake of the brest-fed and formula-fed infants were 105.1+/-20.1mg/day and 288.3+/-37.3mg/day, respectively. The precent of RDA(27%) for brest fed was significantly lower than that(75.4%) of formula fed. The Ca/P ratios were 2.1 in brest fed and 1.6 in formula fed infant. The average calcium and phosphorus intakes of the formula fed infants was higher than that of the brest-fed infants. This data suggests the calcium and phosphorus intakes form human milk sufficiently support the growth of infants. Therefore, the level of calcium and phosphorus recommended dietary allowances for infants should be reduced.

Analysis of Dietary Factors of Chronic Disease Using a Neural Network / 대한지역사회영양학회지

A neural network system was applied in order to analyze the nutritional and other factors influencing chronic diseases. Five different nutrition evaluation methods including SD Score, %RDA, NAR INQ and %RDA-SD Score were utilized to facilitate nutrient data for the system. Observing top three chronic disease prediction ratio, WHR using SD Score was the most frequently quoted factor revealing the highest predication rate as 62.0%. Other high prediction rates using other data processing methods are as follows. Prediction rate with %RDA, NAR, INQ and %RDA-SD Score were 58.5%(diabetes), 53.5%(hyperlipidemia), 51.6%(diabetes), and 58.0%(diabetes)respectively. Higher prediction rate was observed using either NAR or INQ for obesity as 51.7% and 50.9% compared to the previous result using SD Score. After reviewing appearance rate for all chronic disease and for various data processing method used, it was found that iron and vitamin C were the most frequently cited factors resulting in high prediction rate.

Strategies to Improve Elderly Nutrition : Comparisons of Dietary Behavior according to the Mean Nutrient Adequacy Ratio / 대한지역사회영양학회지

A deep understanding of the dietary patterns and nutrient intake is important for assessment of possilbe nutritional risk and for establishing nutrition improvement strategies. This study was conducted toexamine the dietary characteristics of a nutritionally poor elderly group compared to the middle-and highly-nourished group. Elderly participant was recruited from local elderly centers in Suwon city in 1998. Trained dietitians interviewed 119 elderly(35 males, 84 females) aged 60 years and over for collecting dietary data(24-hour recall) and related variables. Male and female subjects were grouped into high, middle, and low according to the mean nutrient adequancy ratio(MAR) tertiles. An analysisof the percentage of RDA(Recommended Daily Allowances of Korea) for each of the 10 nutrients showed that the male low-MAR group consumed below the RDA in all kinds of nutrients, and the female low-MAR group consumed nutrients below the RDA except vitamin C. An evaluation of nutrient density by Index of Nutritonal Quality(INQ) also showed a similar tendency. Thus, the INQ level of the male low-MAR group was significantly lower than the middle-or high-MAR group, especially in protein, vitamin A, thiamin, riboflavin, and phosphorus(p<0.05). Moreover, INQ level of female low-MAR group was significantly lower than that of the high group(p<0.05) in all nutrients. The female low-MAR group's daily food intake were also lower than those of the high-MARgroup in gains, fish, fruits, oil and beverages. The energy distribution from carbohydrates, fats and proteins showed that the male low-MAR group had significantly higher carbohydrate and lower fat proportions compared to each gender high-MAR group, respectively. The male and female low-MAR group had low scores about eating all side dishes. These findings indicate that a moderate increase of the meat/egg/fishes intake was needed by the male low-MAR group for improving nutrition adequacy, and an overall increase of the food quantity and quality was desired for the female low-MAR group. These data could be used for planning a community elderly nutrition program and establishing strategies for tailored guidelines for the individuals.
