  • The necessity of adequate pregnancy weight gain for optimal pregnancy outcome has been recognized. However, the specific components of pregnancy weight gain that might be critical for fetal growth and development have not been elucidated clearly. The purpose of this study was to investigate the correlation of pregnancy weight gain and birth weight with serum leptin levels in women delivered newborns. The subjects were recruited from K university hospital. The subject's characteristic data (age $32.1\;{\pm}\;4.3\;y$, gestational age $39.5\;{\pm}\;1.1wk$, pre-pregnancy weight $58.0\;{\pm}\;8.6\;kg$, pregnancy weight gain $12.7\;{\pm}\;5.5\;kg$, newborn's birth weight $3.5\;{\pm}\;0.5\;kg$) were gathered. Maternal dietary assessment was carried out at the end of pregnancy. After delivery, blood samples were collected from 20 mother-newborn pairs. Serum levels of various lipids and leptin were analyzed. Maternal daily consumption of iron, zinc, folate were lower than the RDA of each nutrient and index of nutritional quality was less than 1 showing that the quality of maternal diet was low. The levels of serum leptin of mothers and infants were $10.2\;{\pm}\;6.7\;ng/ml$ and $1.7\;{\pm}\;0.6\;ng/ml$, respectively. The serum leptin concentrations of male infants $(1.9\;{\pm}\;0.7\;ng\;ml)$ were not different from that of females $(1.7{\pm}0.5\;ng/ml)$. A negative correlation was found between the maternal pre-pregnant BMI and weight gain during pregnancy (r = -0.54, p < 0.05). There was a positive correlation between the pregnancy weight gain and the newborn's birth weight (r=0.59, p < 0.01 There were also positive correlation between newborn's birth weight and newborn's serum leptin levels (r = 0.57, p < 0.01). No correlations were found between maternal serum leptin levels and that of newborn's. Efforts should be made to attain adequate diet and weight gain during the pregnancy to reduce the likelihood of low or over birth weight of newborns.

  • The purpose of this study was to compare the nutritional menu value of self-selected diet in Korean adults residing in different regions. Subjects were recruited and divided into three groups according to the districts where they lived, which included rural district(n=137), coastal district(n=100), and urban district(n=117). Subjects were interviewed using a general questionnaire and 24-hour recall method for dietary intake. The average age of the subjects were 57.5 years for rural district, 57.0 years for coastal district, and 47.9 years for urban district. The contents of energy, calcium, zinc, vitamin $B_2$, and vitamin E in self-selected diet were 76.1%, 60.1%, 73.1%, 68.6%, and 80.4% of RDAs, respectively. Index of nutritional quality(INQ) for calcium and vitamin $B_2$ was below in 1 in region groups. The contents of calcium and vitamin E in self-selected diet of rural and coastal districts were significantly lower than those of urban district. The numbers of food items in diet of rural, coastal, and urban district were 14.6, 15.3, 15.1 for breakfast, 16.5, 11.8, 17.0 for lunch, 14.9, 12.1, 15.1 for dinner, respectively. However, there was no significance in total food intake by regions. The food intakes from cereals, mushrooms, vegetables of rural district, that from fishes of coastal district, and those from sugars, milks, oils of urban district were the highest among three districts. The numbers of dish items in diet of rural, coastal, and urban district were 4.1, 4.4, 4.1 for breakfast, 4.5, 3.7, 4.4 for lunch, 4.0, 3.8, 4.2 for dinner, respectively. Especially, the number of food and dish items in lunch menu of coastal district was the lowest among region groups. According to these results, it could be suggested to add milk and its products in lunch menu of rural and coastal districts and to supplement fish and shellfish like anchovy in diet of rural and urban districts. And it is recommended to increase food and dish items in diets of three region groups.

  • Growth hormone (GH) plays a key role in regulating postnatal growth and can stimulate growth of animals by acting directly on specific receptors on the plasma membrane of tissues or indirectly through stimulating insulin-like growth factor (IGF)-I synthesis and secretion by the liver and other tissues. IGF-I and IGF-Ⅱ are polypeptides with structural similarity with proinsulin that stimulate cell proliferation by endocrine, paracrine and autocrine mechanisms. The initial event in the metabolic action of IGFs on target cells appears to be their binding to specific receptors on the plasma membrane. Current evidence indicates that the mitogenic actions of both IGFs are mediated primarily by binding to the type I IGF receptors, and that IGF action is also mediated by interactions with IGF-binding proteins (IGFBPs). Six distinct IGFBPs have been identified that are characterized by cell-specific interaction, transcriptional and post-translational regulation by many different effectors, and the ability to either potentiate or inhibit IGF actions. Nutritional deficiencies can have their devastating consequence during growth. Although IGF-I is the major mediator of GH's action on somatic growth, nutritional status of an organism is a critical regulator of IGF-I and IGFBPs. Various nutrient deficiencies result in decreased serum IGF-I levels and altered IGFBP levels, but the blood levels of GH are generally unchanged or elevated in malnutrition. Effects of protein, energy, vitamin C and D, and zinc on serum IGF and IGFBP levels and tissue mRNA levels were reviewed in the text. Multiple factors are involved in the regulation of intestinal epithelial cell growth and differentiation. Among these factors the nutritional status of individuals is the most important. The intestinal epithelium is an important site for mitogenic action of the IGFs in vivo, with exogenous IGF-I stimulating mucosal hyperplasia. Therefore, the IGF system appears to provide and important mechanism linking nutrition and the proliferation of intestinal epithelial cells. In order to study the detailed mechanisms by which intestinal mucosa is regulated, we have utilized IEC-6 cells, an intestinal epithelial cell line and Caco-2 cells, a human colon adenocarcinoma cell line. Like intestinal crypt cells analyzed in vivo or freshly isolated intestinal epithelial cells, IEC-6 cells and Caco-2 cells possess abundant quatities of both type Ⅰ and type Ⅱ IGF receptors. Exogenous IGFs stimulate, whereas addition of IGFBP-2 inhibits IEC-6 cell proliferation. To investigate whether endogenously secreted IGFBP-2 inhibit proliferation, IEC-6 cells were transfected with a full-length rat IGFBP-2 cDNA anti-sense expression construct. IEC-6 cells transfected with anti-sense IGFBP-2 protein in medium. These cells grew at a rate faster than the control cells indicating that endogenous IGFBP-2 inhibits proliferation of IEC-6 cells, probably by sequestering IGFs. IEC-6 cells express many characteristics of enterocyte, but do not undergo differentiation. On the other hand, Caco-2 cells undergo a spontaneous enterocyte differentiation. On the other hand, Caco-2 cells undergo a spontaneous enterocyte differentiation after reaching confluency. We have demonstrated that Caco-2 cells produce IGF-Ⅱ, IGFBP-2, IGFBP-3, and an as yet unidentified 31,000 Mr IGFBP, and that both mRNA and peptide secretion of IGFBP-2 and IGFBP-3 increased, but IGFBP-4 mRNA and protein secretion decreased after the cells reached confluency. These changes occurred in parallel to and were coincident with differentiation of the cells, as measured by expression of sucrase-isomaltase. In addition, Caco-2 cell clones forced to overexpress IGFBP-4 by transfection with a rat IGFBP-4 cDNA construct exhibited a significantly slower growth rate under serum-free conditions and had increased expression of sucrase-isomaltase compared with vector control cells. These results indicate that IGFBP-4 inhibits proliferation and stimulates differentiation of Caco-2 cells, probably by inhibiting the mitogenic actions of IGFs.

  • This study was conducted to investigate the effects of residence types ((1) parent house, (2) dormitory or boarding home, (3) boarding home w/o food) on the dietary habits and health status of college women (20-23 y). Overall, 46.1% of college women reported that they were economically middle class and spent 200,000-390,000 won. Additionally, 17.4% of college women considered themselves healthy, while 33.8% reported that they were not healthy. Furthermore, 32.0% of college women had experience to control their weight and 39.8% reported that they exercised to control their weight. There were no significant differences in the height and weight of the subjects according to residential type, but the amount of skeletal muscles mass ($21.0\;{\pm}\;2.6\;kg$) of the subjects that lived in dormitory or boarding home was significantly higher (p < 0.05) than that of women who lived at home. Additionally, 30.8% of students that lived in private residences, 25.0% of students that dwelled in dormitory or boarding homes and 27.7% of students that boarding home w/o food had three regular meals every day (p < 0.05). It has been reported that 18.3% of college students eat processed and instant foods due to their convenience. In the present study, intakes of energy, protein, fat, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, vitamin C, vitamin E and folic acid for the subjects who lived in dormitory or boarding homes was significantly higher than those of students who lived in private residences (p < 0.05). Additionally, intakes of iron, calcium, and zinc were lower in the subjects that boarding home w/o food (p < 0.05). Finally, the blood glucose level was $84.7\;{\pm}\;13.0\;mg/dL$, and differed significantly by residential types (p < 0.05); however, the average glucose levels of all subjects were within the normal range (90-110 mg/dL).

  • 본 연구는 뇌성마비 아동의 성장발달에 기여할 간식개발을 위한 기초자료를 수집하기 위해 만 $1{\sim}7$세의 뇌성마비아동과 어머니 각각 99명을 대상으로 뇌성마비 아동의 신체발육과 식습관, 영양섭취상태, 간식섭취실태를 조사한 결과는 다음과 같았다. WLI(Weight-Length Index)를 기준으로 비만도를 판정한 결과 저체중아비율은 45.5%, 정상아는 45.5%, 과체중아는 6.0%, 비만아는 3.0%로 나타났다. Waterlow 분류법을 이용하여 영양불량상태의 정도를 분류 해 본 결과 정상인 아동이 76.6%, 쇠약인 아동이 10.3%, 성장부진인 아동이 8.0%, 성장부진과 쇠약인 아동이 5.0%로 나타났다. 아동들의 영양섭취실태를 알아보기 위해 아동들이 식사 섭취한 내용을 한국인 일일 영양권장량과 비교분석한 결과 아연과 엽산의 섭취량 비율(%RI)은 모든 연령대에서 권장섭취량에 미달하였다. 권장섭취량의 75% 이하를 섭취하는 아동의 비율은 엽산(76.8%)과 아연(76.8%), 열량 (59.8%), 칼슘(52.4%), 철(52.4%)의 경우 50% 이상이었고, 권장섭취량의 125% 이상을 섭취하는 아동들의 비율이 단백질은 85.4%, 비타민 B6은 53.7%로 나타났다. 어머니들이 주로 구입하는 시판간식은 우유 및 유제품(43.5%)과 과일류 (33.3%)가 많았고 시판 간식에 대해서는 첨가물(보존료, 색소)을 가장 문제점으로 생각하고 있었다. 아동들을 위해서 성장발달에 도움이 되는 간식(50.5%)이 새로 개발되기를 가장 바라고 있어서 이에 대한 요구도가 가장 높았으며, 새로개발되기를 바라는 간식의 종류로는 떡류(47.5%)와 과자류 (24.2%) 및 빵류(22.3%)를 선호하였다. 본 연구결과를 통하여 뇌성마비 아동은 정상아동에 비해 성장이 느리고 영양소섭취량도 현저히 낮은 것을 알 수 있었다. 본 연구대상 아동들이 현재의 식품 섭취량으로만 계속 섭취한다면 정상적인 성장을 할 수 없을 것이다. 따라서 뇌성마비 아동과 같이 저영양 상태에 있는 아동의 성장발달과 건강증진을 위한 간식제품의 개발이 시급한 것으로 보인다. 새로 개발될 뇌성마비 아동을 위한 간식모형 도출결과 간식제품은 권장섭취량과 비교했을 때 가장 섭취가 부족한 것으로 나타난 아연과 엽산을 보충하여 성장발달에 보조역할을 할 수 있고 아동들의 저작기능을 향상시키고 손에 잡기 쉬운 형태인 떡의 형태가 가장 적합한 형태로 도출되었으므로 향후 이러한 간식 개발에 대한 연구가 필요하다. 본 연구의 제한점은 뇌성마비 아동의 식사 섭취 조사의 어려움으로 인하여 일일의 식품섭취량만을 조사하여 보고한 것이라 할 수 있다. 그리고 아연과 같은 미량영양소의 영양 상태를 정확하게 측정할 수 있는 생화학적 조사가 더 이루어져야 할 것이다.

  • Recently, Jersey cattle was introduced and produced by embryo transfer to Korea. This study was conducted to investigate the differences of milk compositions between Jersey and Holstein cows and the relationship between days in milk (DIM) and milk compositions during early lactation. Data were collected from twelve lactating cows from Department of Animal Resources Development at National Institute of Animal Science. Cows in parity 1 were used, and calved at spring from April to March of 2017. All cows were housed in two sections within a free-stall barn, which divided into six from each breed, and received a basal total mixed ration. Milk samples of each cow were collected at 3 DIM and 30 DIM for analyzing the milk compositions, including fatty acids (FA), amino acids and minerals. Total solids, citrate, and milk urea nitrogen level were differed between the breeds (p < 0.05). As DIM went from 3 to 30, milk protein, total solids, and somatic cell count decreased (p < 0.05), but lactose increased in all breed milk (p < 0.05). Citrate and free fatty acid (FFA) elevated in Jersey milk (p < 0.05), whereas reduced in Holstein milk (p < 0.05). Proportions of some individual FA varied from the breeds. Myristic (C14:0), palmitic (C16:0), and arachidonic acid (C20:4) in milk from all cows were higher at 3 DIM than at 30 DIM (p < 0.05). Also, stearic (C18:0) and oleic acid (C18:1) were lower at 3 DIM than at 30 DIM (p < 0.05), and the C18:1 to C18:0 ratio was significantly differed in DIM × breed interactions (p < 0.05). The contents of the individual amino acids did not differ from the breeds. Calcium, phosphorous, magnesium, and zinc (Zn) contents was significantly increased in Holstein milk than Jersey milk at 3 DIM. Also, K and Zn concentrations were higher in Holstein milk than in Jersey milk at 30 DIM (p < 0.05). It was concluded that Jersey cows would produce more effective milk in processing dairy products and more proper energy status compared with Holstein cows in early lactation under the same environmental and nutritional conditions.

  • It is a common clinical practice to recommend taking iron supplements for pregnant women during gestation. Although it is required to ensure adequate iron stores during pregnancy, there has been some debate over the interference effects of excessive iron load, because it is possible to compete in the transport in the intestine and placenta and in binding to serum proteins of other trace minerals. In this study, maternal and neonatal serum concentrations of Fe, Zn, Cu, Se, Cr, Mn, and Co were assessed along with maternal Fe intakes. A total of 124 pregnant women and their term neonates participated voluntarily in this research. The women were divided into one of the three groups {high Fe intake (HFI), median Fe intake (MFI), and low Fe intake (LFI)} by their total Fe intakes and one of the two groups (Anemic and Normal) by their Fe nutritional status. All the data were compared among the three groups and between the two groups also. Total Fe intakes of HFI, MFI, and LFI groups were 140.8 ${\pm}$ 76.1, 68.0 ${\pm}$ 11.2, and 30.2 ${\pm}$ 8.6 mg/day, respectively. Those of Anemic and Normal groups were 90.1 ${\pm}$ 74.8 and 86.6 ${\pm}$ 46.8 mg/day, respectively. Maternal Hb concentration and Hct were not significantly different among HFI, MFI, and LFI groups but those were significantly different between Anemic and Normal groups. However, neonatal Hb concentration was not significantly different among HFI, MFI, and LFI groups and between Anemic and Normal groups either. Maternal serum Fe concentrations of the three groups, HFI, MFI, and LFI, were similar but that of Anemic group was significantly lower compared to Normal group. However, there was no significant difference in neonatal serum Fe concentrations among the three groups and between the two groups either. Serum concentrations of the other trace minerals in both mothers and neonates were not significantly different among HFI, MFI, and LFI groups and between Anemic and Normal groups. In addition, in the maternal serum, Fe concentration was positively correlated to Zn and Se concentration, respectively. As for the neonatal serum, Fe concentration showed a positive correlation to Zn, Cu, Mn, Se, and Co concentration, respectively. No trace mineral concentration was found to correlate negatively to Fe concentration in both maternal and neonatal serum, The results in this study indicate that Fe intakes of pregnant women, even if it is considerably above the level of estimated average requirement (EAR), may not affect serum Fe concentration in both mothers and neonates. In addition it might not influence adversely on the availability of other trace minerals including Zn and Cu in both mothers and neonates.

  • 본 연구는 한국인의 영양상태를 파악할 수 있는 반정량 식품섭취빈도 조사지를 개발하고 이 조사지의 타당도를 검증하기 위하여 실시하였다. 본 연구에서 개발된 반정량 식품섭취빈도 조사지는 국민건강영양조사의 빈도가 높고 영양소별 섭취량에 대한 기여도가 높은 급원 식품을 참고하였고 비슷한 영양소별, 지방 함량, 조리 방법 등을 고려하여 88개의 식품항목으로 선정하였다. 1회 섭취 분량은 0.5인분, 1인분, 1.5인분의 3개의 구간으로 나누었고 섭취 빈도는 지난 1년 동안 평균적으로 얼마나 자주 먹었는지를 9개의 구간으로 분류한 반정량 식품섭취빈도 조사지를 개발하였다. 개발한 조사지의 타당도를 평가하기 위하여 건강검진을 목적으로 대학병원의 건강증진센터에 내원한 111명을 대상으로 반정량 식품섭취빈도 조사지와 3일 식사 기록지를 동시에 조사한 후 두 조사방법에 의한 영양소 섭취량의 차이를 분석하였다. 그 결과 남녀 모두에서 식사기록법보다 식품섭취빈도 조사법에서 열량, 탄수화물, 단백질, 지방의 섭취량이 유의적으로 높아 식품섭취빈도법이 식사 기록법보다 다소 과대 추정되는 것을 알 수 있었다. 두 조사방법에 의한 영양소 섭취량의 spearman 상관 계수를 보면 평균 0.402이었고, 포화지방산이 0.121로 가장 낮았고, 열량이 0.583으로 가장 높은 상관성을 보였다. 열량, 탄수화물, 단백질이 각각 0.583, 0.500, 0.466으로 다량영양소가 비교적 높은 상관성을 보였다. 또한 알코올도 0.527로 유의적인 높은 상관성을 보였다. 본 연구에서 개발된 반정량 식품섭취빈도 조사지는 지금까지 보고된 국내의 여러 연구에서 제시한 상관성의 범위를 크게 벗어나지 않았고 탄수화물, 단백질, 지방의 다량영양소와, 열량, 섬유소, 알코올, 그리고 칼슘, 인, 칼륨, 마그네슘, 아연 등 미네랄 등과 유의적인 상관관계를 보여 이러한 영양소와 관련 있는 만성질병과의 역학연구에 유용하게 사용 될 수 있을 것으로 사료된다. 그러나 상관관계가 낮게 보인 비타민과 지방산 종류의 섭취측정에는 어려움이 있다.
