Adequate nutrient intake during pregnancy is important to fetal and maternal health. The purpose of this study was to investigate the factors affecting birth weight and gestational age and to provide basic data to promote more favorable pregnancy outcomes. Data were collected from 234 pregnant women at two hospitals in Seoul. Demographic characteristics, anthropometric measurements and health related habits were obtained using a questionnaire at the hospital visit during the second trimester. Dietary intakes were estimated by 24 hour recall at the hospital visit during the second trimester. Data on pregnancy outcomes, including birth weights and gestational ages, were obtained from hospital records after delivery. Birth weights were divided into a low birth weight group (birth weight<3.1 kg), a normal birth weight group (3.1-3.6 kg) and a high birth weight group (>3.6 kg). Gestational ages were divided into tertiles according to the gestational age of the subjects: group 1 (<38.53 weeks), group 2 (38.53-40.00 weeks) and group 3 (>40.00 weeks). The number of family members was significantly lower in the low birth weight group than in the normal birth weight group (p<0.05). In the low birth weight group, pregnancy weight was significantly lower than in the high birth weight group (p<0.05) Health related habits were not significantly different among any of the groups. Intakes of fiber, phosphorous, iron, vitamin $B_6$ and folic acid were significantly higher in the high birth weight group than the low birth weight group (p<0.05). Gestational age was not significantly affected by nutrient intakes, but birth weight was affected by nutrient intake in the results of this study. Therefore, the adequacy of nutrient intake is important for the improvement of pregnancy outcomes.
The purpose of this study was to determine the effect of lift to the shoe of the affected limb on gait patterns in subjects with hemiplegia. The subjects of this study were 18 post-stroke hemiplegics. For the study, insole of the paretic side was lifted 10 mm higher, and duration of dynamic weight bearing was measured. before and after the lift application. For the measurement of carry-over effect of lift, we got data of there three items prior to and 3 weeks after lift application and 3 days after removal of the lift. Dynamic weight bearing was significantly decreased in heel contact and footflat phases only when just after application of the lift, without any change after 3 weeks application. In heel-off phase, dynamic weight bearing did not show any significant difference between before and just after application of lift whereas significantly decreased after 3 weeks application. According to this study, lift applied to the shoe of the paretic limb was not significantly effect in inducing dynamic weight bearing, but changed a dynamic weight bearing.
Objectives The purpose of this study was to investigate the effect of oriental treatment on pediatric overweight and obesity. Methods From the December 2006 to the May 2008, 19 children were treated of obesity control in J Korean Hospital, electrolipolysis, auricular acupuncture was done 2 times per week for 4 weeks with the consulting of diet and exercise. Nine children were treated for 9 weeks. We checked the change of weight at treatment time and the body composition measured by bioelectrical impedance analysis(BIA) per 2 weeks. Results After 4 weeks treatment, the weight loss was 2.67${\pm}$1.75kg. And after 9 weeks treatment, the weight loss of 9 children was 5.91${\pm}$2.73kg. Total fat mass measured by BIA significantly decreased 2.38${\pm}$1.19kg after 4 weeks. BMI and the weight loss of children were significantly correlated. After 4 weeks treatment the BMI significantly decreased 1.43${\pm}$0.89kg/m$^2$. After 8 weeks treatment the BMI of 9 children significantly decreased 3.31${\pm}$1.47kg/m$^2$. Conclusions The pediatric obesity could be effective treated by herdal medicine and electroacupuncture.
Effect of the amount of fertilizer, plant density, and harvesting time on the production of tobacco leaf protein and fresh biomass was investigated. Flue-cured tobacco(M tabacum, L., cv. NC 82) seedlings were transplanted in the field dressed 200kg N per ha at 1$\times$105, 3$\times$105, 5$\times$105, 7$\times$105 plants per ha, and were harvested at the time when 6 and 10 weeks after transplanting, respectively. Harvest at 10 weeks after transplanting increased greatly number of leaves per plant and fresh weight of a plant, Precentage of senescent leaf weight, but significantly decreased fresh weight of a leaf and total protein contents g-1 fresh weight of leaf and stalk over the amount obtained from the harvest at 6 weeks after transplanting. Also, fresh leaf numbers of a plant, fresh weight of a leaf and of a plant, and total protein contents g-1 fresh weight of biomass were more decreased, but percentage of senescent leaf weight were remarkably increased under higher plant density. Therefore, it was seemed that harvesting at 6 weeks after transplanting under 1$\times$105 plant density per ha is more effective for producing higher yield of biomass and protein per plant than 10 weeks harvesting with 7$\times$105 population per ha. A trend was observed that biomass and protein yields per ha are positively correlated with plant population. Biomass yield per ha was the greatest at 7$\times$105 density(80.5t), but the peak of protein yield was at the near of 5$\times$105 population(2454kg as total protein) per ha on the regression curve. It was assumed that if tobacco plants are transplanted under 5$\times$105 plant density at the mid of May, and thereafter harvest at 6 weeks repeatedly during the growing season, it is possible to harvest 2~3 times per year, and to yield more 6.024kg of protein and over 140me1ric tons of fresh biomass ha 1 year 1 statistically in the korea tobacco growing regions.
Purpose: To identify the effects of modified parenteral nutrition (PN) and enteral nutrition (EN) regimens on the growth of very low birth weight (VLBW) infants. Methods: The study included VLBW infants weighing <1,500 g, admitted to Chungnam National University Hospital between October 2010 and April 2014, who were alive at the time of discharge. Subjects were divided according to 3 periods: period 1 (n=37); prior to the PN and EN regimen being modified, period 2 (n=50); following the PN-only regimen modification, period 3 (n=37); following both PN and EN regimen modification. The modified PN regimen provided 3 g/kg/day of protein and 1 g/kg/day of lipid on the first day of life. The modified EN regimen provided 3.5-4.5 g/kg/day of protein and 150 kcal/kg/day of energy. We investigated growth rate, anthropometric measurements at 40 weeks postconceptional age (PCA) and the incidence of extrauterine growth restriction (EUGR) at 40 weeks PCA. Results: Across the 3 periods, clinical characteristics, including gestational age, anthropometric measurements at birth, multiple births, sex, Apgar score, surfactant use and PDA treatment, were similar. Growth rates for weight and height, from time of full enteral feeding to 40 weeks PCA, were higher in period 3. Anthropometric measurements at 40 weeks PCA were greatest in period 3. Incidence of weight, height and head circumference EUGR at 40 weeks PCA decreased in period 3. Conclusion: Beginning PN earlier, with a greater supply of protein and energy during PN and EN, is advantageous for postnatal growth in VLBW infants.
This study was conducted in order to observe the changes in cellular association of seminiferous tubules from 4 to 22 weeks of age and to obtain the cycle and relative duration of seminiferous epithelia from 24 weeks of age in male ducks. Fifety-five male ducks were used in the experiment and divided into 11 groups, consisting of 5 male ducks each, with 2 weeks intervals from 4 to 24 weeks of age. The results were summarized as follows: 1. The body and testes weight showed most rapid increase during 4 to 6 weeks and 18 to 22 weeks of age, respectively. The seminiferous tubules were obruptly enlarged in diameter of tubules during 18 to 22 weeks of age. 2. Gonocytes were seen from 4 to 6 weeks of age, however they were not observed as from 8 weeks of age. Both type Ap spermatogonia and type Ad spermatogonia occured from 8 to 12 weeks of age, while spermatocytes and spermatids were beginning to appear at 16 weeks and 18 weeks of age, respectively. Spermatozoa were first observed at 20 weeks of age. Full spermatogenic activity was completed at the age of 20 weeks. 3. Average paired weight of the testes in male ducks was 78g at 24 weeks of age and its ratio to the body weight was approximately 2.5 percent. 4. Average diameter of seminiferous epithelium at 22 weeks of age was $232{\mu}m$, and average numbers of Sertoli cell, spermatogonia, spermatocyte, spermatids and spermatozoa in the cross section of seminiferous epithelium were 15.30, 59.08, 41.78, 71.11 and 165.30, respectively. Spermatogonia and spermatids were classified into 2 and 4 types, respectively. 5. The cycle of the seminiferous epithelium could be divided into 5 stages at 24 weeks of age. The relative frequencies of stages from I to V were 13.5%, 25.0%, 22.3%, 20.6% and 18.7% respectively. Thus, establishment of spermatogenesis in male ducks were beginning to appear at 20 weeks of age.
Purpose : This study was carried out to investigated the effects of Saenghyeolbosu-Tang on the morphometric changes of femur, and on the hormones and cytokines associated with bone metabolism in ovariectomized rats. Methods : Twenty-four female Sprague-Dawley rats were divided into sham operated group(normal), ovariectomized group(control), and treated with extract of Saenghyeolbosu-Tang group(treated). Each group was evaluated the changes of body weight at 0, 3, 6, 8, weeks after ovariectomy. Morphometric analysis(femur weight, femur/body weight, femur ash weight, femur ash/body weight, cross sectional area of compact bone and cancellous bone of femur) and histopathological examination were performed at 8 weeks after ovariectomy. Estrogen and cytokines($TNF-{\alpha},\;IL-1{\beta}$, IL-6) assay were performed at 8 weeks after ovariectomy. Results : 1. The femur weight(g) of treated group(1.59${\pm}$0.08) was significantly increased(p<0.05)compared with the control group(1.50${\pm}$0.07) at 8 weeks. 2. The femur/body weight(g) of treated group(5.27${\pm}$0.36) was significantly increased(p<0.05) compared with the control group(4.78${\pm}$0.37) at 8 weeks. 3. In the cross sectional area of cancellous bone of femur(${mm^2}$) the treated group(1.60${\pm}$0.20)was significantly increased(p<0.01) compared with the control group(1.19${\pm}$0.19) at 8 weeks. 4. The serum estrogen level(pg/ml) of treated(83.67${\pm}$27.44) and control group(800.49${\pm}$22.27)showed no significantly different changes at 8 weeks. 5. The serum $TNF-{\alpha}$ level(pg/ml) of treated(33.71${\pm}$6.43) and control group(41.35${\pm}$8.47) showed no significantly different changes at 8 weeks. 6. The serum $IL-1{\beta}$ level(pg/ml) of treated group(53.78${\pm}$10.83) was significantly decreased(p<0.001) compared with the control group(79.80${\pm}$11.40) at 8 weeks. 7. The serum IL-6 level(pg/ml) of treated group(55.52${\pm}$9.02) was significantly decreased(p<0.01) compared with the control group(69.69${\pm}$7.95) at 8 weeks. Conclusion : This study shows that Saenghyeolbosu-Tang inhibits bone resolution in ovariectomized rats. These results may be related to the inhibitory effect of Saenghyeolbosu-Tang on the secretion of $IL-1{\beta}$ and IL-6 in the Pathogenesis of osteoporosis.

Both ODC and PRDM16 genes were known to be associated with body weight traits in chicken. These two genes were located on GGA3 and GGA21, respectively, where the QTLs of body weights are located. Therefore, the objectives of this study were to identify the SNPs in these two genes and their associations with body weight traits in Korean native chicken. Fluidigm Dynamic Array integrated fluidic circuits (IFCs) assay was used to genotype 7 SNPs consisting g.-353C>T, g.2136A>G, g.2524T>C, g.3607C>T SNPs of the ODC gene, and g.182216C>T, g.182290A>T, g.182491A>T SNPs of the PRDM16 gene. Statistical analysis showed that g.2136A>G SNP of the ODC was associated with body weight at 20 weeks of age and slaughter weight, and g.3607C>T SNP of the ODC was associated with body weight at 2 weeks of age. Association between g.182216C>T SNP of the PRDM16 and body weight at 12 weeks of age has also been revealed. In addition, g.182491A>T SNP of PRDM16 has significant correlation with body weight (BW) at 8 weeks, BW at 10 weeks and BW at 14 weeks of age. These results suggested that both ODC and PRDM16 could be strong candidate genes for body weight traits in Korean native chicken.
This study was performed to investigate the effect of kangaroo care on anxiety and confidence and gratification of mothering role in mothers of low birth weight infants. The subjects were 30 mothers of low birth weight infants, sixteen for the kangaroo care group and fourteen for the control group, whose infants hospitalized in two neonatal intensive care unit at two university-affiliated hospital. The kangaroo care was applied 9 times during the twenty six days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a low birth weight infant wearing a diaper and a hat is placed on its mother's chest. The questionnaire, state anxiety was completed before beginning the first intervention. The questionnaire, state anxiety and confidence and gratification of mothering role were completed at 2 weeks after discharge. The data were analyzed by a SPSS program. The results were as follows : 1. There were no significant differences in the state anxiety between the kangaroo care and the control group before beginning the first intervention. The state anxiety was significantly lower in kangaroo care group than in control group. 2. The confidence of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 3. The gratification of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 4. In mothers of low birth weight infants, the state anxiety was negatively correlated to the confidence of mothering role and the gratification of mothering role at 2 weeks after discharge. And the confidence of mothering role in mothers of low birth weight infants was positively correlated to the gratification of mothering role at 2 weeks after discharge. These results suggest that kangaroo care is an effective nursing intervention for mothers of low birth weight infants in reducing the state anxiety, improving the confidence and gratification of mothering role.
This study was carried out to increase the breeding rate using sustained recombinant bovine somatotropin (bST) and examine the reproductive disorder and disease prevalencies of cow and calf, respectively. Sixty cows were allotted randomly to three groups in randomized complete block design; (1) No treatment, (2) 500 mg bST two times + 250 mg bST SC injection five times from 3 weeks before to 9 weeks after parturition every two weeks, (3) 500 mg bST two times before 3 weeks parturition + 250 mg bST SC injection three times from five to 9 weeks after parturition every two weeks. Developmental data of birth weight, weaning weight, total gain and average daily gain in control was $22.9{\mu}0.45$ kg, $88.0{\mu}1.13$ kg, $65.1{\mu}0.74$ kg and $0.54{\mu}0.08$ kg, respectively. There is no significant difference between Group 1 and 3 in the examined factors. However, there is significant difference between Group 1 and 2 in the birth weight ($24.4{\mu}0.88$ kg), weaning weight ($101.0{\mu}1.77$ kg), total gain ($76.7{\mu}0.9$ kg) and average daily gain ($76.7{\mu}0.9$ kg). Total gain was showed higher in Group 2 and 3 than Group 1 in the >2nd parity, and in Group 2 than Group 1 and 3 in the 1st parity. There is no significant difference in the BCS, no return days and disease occurrence of cow and calf by bST treatment. Number of service per conception was slightly increased in the Group 3 compared to Group 1 and 2. To increase the breeding ability of Hanwoo, it is recommended that 500 mg bST two times + 250 mg bST injection five times from 3 weeks before to 9 weeks after parturition every two weeks.
