  • 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<0.001). Lipid content, determined gravimetrically in colostrum and matured milk, was 1.50g/이 and 3.2g/dl, respectively. Also the total cholesterol content(mg/dl) in preterm milk tends to increase from 14.16mg/dl to 15.20mg/dl, while the total cholesterol(mg/g lipid) concentration higher significantly in colostrum(12.36mg/g) than in mature(5.73mg/g)(p<0.001). The total unsaturated fatty acid contents in preterm milk were higher in colostrum than in mature milk and the total saturated fatty acids were higher in mature milk. The average DHA contents of colostrum and matured milk was 0.64%, 0.53% and the P/M/S ratio of preterm milk were 0.63 : 1.05 : 1.00, 0.47 : 0.79 : 1.00, respectively. Also, $\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.

  • Purpose: The purpose of this study was to analyze the relationship among life style, body composition and Bone Mineral Density (BMD) in community dwelling Korean adults. Methods: Data were collected from 140 adults who participated in a health check-up program at community health departments in D city, Choong-chung providence. Subjects' life style was assessed with a structured interview survey. Body composition analyses were performed by the bioimpedence method and BMD was measured by peripheral dual energy X-ray absorptionmetry. Results: Among the subjects, 39.3% showed normal BMD values, 50.7% were osteopenic and 10% were assessed as osteoporotic. BMD was significantly different by gender, age, education, economic status and BMI. Subjects who had three or more meals/day had higher BMD then who had less than three meals (t=-2.273, p=.026). BMD was not influenced by regular exercise, alcohol consumption, or smoking. In terms of body composition, there was a significant relationship between fat free mass and BMD (r=.172, p=.043). Conclusion: Implementing an osteoporosis prevention program would be warrented considering the significant proportion of osteopenic or osteoporotic subjects. Regular eating habit with three meals for adequate nutrition need to be emphasized to prevent further bone loss in this population. Among the body composition, fat free mass seem to be the mostly predicting factor for BMD.

  • In recent, the roles of oleic acid, most abundant fatty acid in myelin, were investigated in relation to the brain functions. This study examined the effects of diets either with desirable ratios of $\omega$6/ $\omega$9 and P/M/S (mixed oil-fed group: MO) or with defficient in $\omega$3 series fatty acids (safflower oil-fed group: SO) on the oleic acid composition in RBC and brain synaptosomal, mitochondrial & microsomal phospholipids. The desirable fatty acid composition was computer-searched with different fats and oils to meet right ratios of both $\omega$6/ $\omega$3 and P/M/S. Diets were fed 3 weeks before conception and new-born pups were fed maternal milk from the same mothers and same diets until 9 wks of age. At 3 wks of age, the compositions of oleic acid in brain subcellular fractions and red blood cells were constantly remained whatever the composition of dietary fatty acids. But at 9 wks of age, the composition of oleic acid in synaptosome and mitochondria were significantly higher in MO group than SO group. The composition of oleic acid in milk was significantly higher in MO group than SO group, but in case of SO group, that of oleic acid was increased by 48%, in comparison with dietary fatty acid compositions. -9 desaturase index (18:0\longrightarrow8:1) of brain synaptosome was significantly higher in MO group than SO group at 3 and 9 weeks of ages, but that of brain microsome was higher in SO group than MO group at 9 wks of age. Taken together, the presences of oleic acid in the diet was important to maintain brain functions. The origins of oleic acid in brain may suggests two hypotheses; first, the central nervous system has priority for the uptake of oleic acid, and second the nervous system can synthesize all the oleic acid it needs, independently of its presence in the diet.

  • Samples of Clitoria ternatea L. (Cunh$\tilde{a}$) were harvested at 35, 50, 70, and 90 d after a uniformity harvest in a field study designed as a completely randomized design with a total of 18 experimental plots. The dry matter yield of the whole plant was separated quantitatively into leaves, stems, and pods at each harvesting age. Chemical analyses and in vitro gas production kinetics were performed to assess the quality of the plant parts. Yields, chemical composition, and estimates of gas production parameters were analyzed by fitting a mixed statistical model with two types of covariance structures as follows: variance components and an unrestricted structure with heterogeneous variances. Fast and slow gas yielding pools were detected for both leaves and stems, but only a single pool was detected for pods. The homoscedasticity assumption was more likely for all variables, except for some parameters of the gas production kinetics of leaves and stems. There was no presence of typical pods at 35 and 50 d. In the leaves, the fibrous fractions were affected, whereas the non-fibrous fractions were unaffected by the harvesting age. The harvesting age affected the majority of the chemical constituents and gas kinetic parameters related to the stems. The leaves of this legume were the least affected part by the aging process.

  • Weanling female Sprague Dawley rats were fed diets containing 22mg pyridoxine HCI/kg diet(control diet) and 1.2mg pyridoxine HCI/kg diet(deficient diet). One deficient group and one control group were fed their diets throughout the period of growth, gestation and lactation. After the pups were born and weaned, the deficient group was divided into two groups. Therefore, one(DC) switched to control diet and the other continued the same deficient diet until 10 week-old. Analysis of chemical composition of fatty acid in the total brain lipid was conducted in the pups of 5, 10, 15, 21, 35, 50 days of age. Arachidonic acid content was significantly decreased in the deficient group at 5 days compared to the control, but at almost all ages, there were no significant differences in fatty acid contens among all the groups. The fatty acid compositions of the brain phospholipids were determined on pups at 1, 14, 21, 35, 70 days of age. The content of $C_{20}\;_{4}$ in the brain phosphatidylcholine birth and contents of $C_{22}\;_{4}$ and $C_{22}\;_{5}$ at birtd, and $C_{22}\;_{5}$ and $C_{22}\;_{6}$ at 14 days in the phosphatidylethanolamine were depressed in the deficient group. These changes were not consistent with ages. Therefore, it may reflect that the major part of the changes occuring in the pyridoxine depleted rats depends, not so much on the pyridoxine depletion itself, as on the age or development of the rats.

  • Objectives The study was designed to find out the relationships between low weight and growth, skeletal maturity among children by analyzing body composition and bone age. Methods Subjects were composed of 336 children from six years to seventeen years of age, without any other diseases related to growth, who visited the department of oriental pediatrics East West Neo Medical Center at Kyung Hee University and were measured their body composition and bone age. Results There were significant correlations between decreasing of RH-MPH(%) and low weight. 1. As obesity index decreased, the RH-MPH was also decreased. 2. The RH-MPH(%) of the low weight group according to the obesity index classification was significantly decreased than that of the normal weight group. 3. The skeletal maturity was more decreased in the low weight group. However, the differences between the two group was not significant. 4. The RH-MPH(%) was increased in children who developed secondary sexual character. Skeletal maturity was decreased in children who developed secondary sexual character. 5. The RH-MPH(%), and skeletal maturity was not significantly different between males and females. 6. Only in the case of children without development of secondary sexual character, low weight caused significant RH-MPH(%) decrease. Conclusions Low weight children might be smaller than what it supposed to be. Also, low weight could affect body development more to the children than to the teenager.

  • The objectives of this study were to obtain normative data for 45 mother-daughter pairs on spine, femur(neck, ward's triangle, trochanter) and total body BMD (bone mineral density) measured by dual energy X-ray absorptiometry, anthropometric measurement, body composition, biochemical markers, nutrient intakes and energy expenditure, to determin the interrelations of these factors within each group, to measure familial resemblance for each variable. We observed significantly positive correlations between height, weight, head, hip and calf circumferences, tricep, femur and calf skinfold thickness, total lean body mass(=weight-total fat body mass-bone mineral content), protein and fat intakes, Ca index, serum total protein and albumin of monter-daughter pairs(p<.05-p<.001). Among mothers, age, osteocalcin, higher, weight, Ca and energy intakes were predictors of BMDs. Among daughters, weight and energy intake were predictors of BMDs. The BMD in lumbar spine(r=.48, p<.01), femoral neck(r=.38, p<.05), ward's triangle(r=.36, p<.05) of the mothers were significantly correlated with those of the daughters, after adjustment for mother's age, hight, weight, osteocalcin, Ca and energy intakes and daughter's weight, energy intake. In regression analyses, mother's BMD also were positively associated with daughter's BMD in lumbar spine, femoral neck, ward's triangle. Our findings support that mothers with low BMD tended to have daughters with low BMD. In the age groups studied, as well genetic factors as environmental factors may have an important role in determining BMD. This study suggests that women may successfully enhance their genetically determined BMD through adequate nutrient intakes and weight bearing exercise.

  • The Wolchul Mt. area is composed of a biotite granite and a pink feldspar granite. These granites are distinctly different in terms of their field occurrence, mineralogy, trace element and REE composition, as well as their isotope ages. The biotite granite has higher ferromagnesian elements and lower lithophile trace element abundances than the pink feldspar granite. The biotite granite has high Sr and Ba while the pink feldspar granite has high Rb. On the Rb-Sr-Ba diagram the biotite granite plots as a granodiorite while the pink feldspar granite belongs to a strongly differentiated granite. The ${\Sigma}$ LREE/ ${\Sigma}$ REE for the biotite granite is 0.95 and for the pink feldspar granite it is 0.88. The ratio shows a steep decrese in LREE while HREE is essentially constant. Based on the Eu/Sm, $[La/Lu]_{cN}$ and low Eu(-), the biotite granite has quartz diorite to granodiorite composition while the pink feldspar granite, with a relatively high Eu(-) anomaly, falls into the monzo- to syenogranite classification. The silica vs. trace element diagrams for the two granites indicate that the biotite granite could have formed near to a continental margin or volcanic island setting environment while the pink feldspar granite formed within a continental plate or as result of plate collision. The biotite granite has a U-Pb zircon age of 175 Ma, i.e. Middle Jurassic. The pink feldspar granite is younger, it has a K-Ar orthoclase age $93.6{\pm}1.5$ Ma which is Late Cretaceous age.
