Accuracy of dietary assessment depends on correct estimation of quantity as well as correct data on composition of the products. Milk and soymilk were considered quite homogeneous in items of package size and composition. One serving size of fluid milk and soymilk is considered 200 mL but there are products with different amounts on the market. This study was conducted to investigate variations of amounts and composition of fluid milk and soymilk products of one portion siz on Korean market. Twenty-nine milk products were purchased and categorized into 8 groups-regular, low-fat, skim, chocolate, strawberry-flavored, banana-flavored, and black soybean-added. Sixteen fluid soymilk products were purchased and categorized into 4 groups-regular, infant, black sesame or black soybean added and others. Actual volume of each product was measured by mass cylinder and compositions of major nutrients on the package were compared to the values in the most widely used nutrient DB in Korea. Amounts of milk specified on the package of purchased products were 182.3-318.5 ml, the largest being banana-flavored milk. Amounts of soy milk were 184.3-240.5 mL, the largest being regular soymilk. Measured amount of each products were close to the amount on the package (<5%). Contents of macronutrients on the package were different from the food composition table in several products. The amounts of calcium varied greatly among the products due to the popularity of adding calcium to milk and soymilk products recently. These variations in the amount and contents of major nutrients in milk and soymilk products can lead to considerable error to the results of dietary assessment unless the amount and the composition of each product are regularly updated in the food composition table whenever the new products are introduced in the market.

The purpose of this study is to provide basic data for the medical nutrition therapy of premature infants. The general characteristics, presence of metabolic disorders, hematological profile and feeding methods were compared between the premature infant group (<37 weeks, n=61) and the full-term infant group (37$\sim$42 weeks, n=165). Birth weight (p<0.0001), birth length (p<0.005), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores (p<0.0001) of the neonates were all statistically lower in the premature infant group. Jaundice cases (p<0.0001) were statistically higher in the premature infant group. White blood cell counts (WBC: p<0.005), mean corpuscular volume (MCV: p<0001), mean corpuscular hemoglobin (MCH: p<0.005), mean corpuscular hemoglobin concentration (MCHC: p<0.005), and mean platelet volume (MPV: p<0.05) were statistically lower in the premature infant group. The premature infant group were fed a higher rate of premature formula than breast milk and the full-term infant group were fed a high rate of human milk at a higher rate, showing differences in kinds of feeding methods (p<0.0001) between the two groups. An infant's birth weight showed a significantly positive correlation with the infant's birth length (p<0.0001), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores(p<0.0001). The birth length also showed a significantly positive correlation with both head circumference (p<0.05) and chest circumference (p<0.05). Head circumference showed a significantly positive correlation with chest circumference (p<0.0001) and Apgar scores (p<0.0001). Chest circumference showed a significantly positive correlation with Apgar scores (p<0.0001). In addition, the Apgar Score at of 1 minute after birth showed a significantly positive correlation with the Apgar score at of 5 minute after birth (p<0.0001).

Objective : Milk fat globule-epidermal growth factor VIII (MFG-E8) may play a key role in inflammatory responses and has the potential to function as a neuroprotective agent for ameliorating brain injury in cerebral infarction. This study aimed to determine the role of MFG-E8 in brain injury in the subacute phase of cerebral ischemia in a rat model. Methods : Focal cerebral ischemia was induced in rats by occluding the middle cerebral artery with the modified intraluminal filament technique. Twenty-four hours after ischemia induction, rats were randomly assigned to two groups and treated with either recombinant human MFG-E8 or saline. Functional outcomes were assessed using the modified Neurological Severity Score (mNSS), and infarct volumes were evaluated using histology. Anti-inflammation, angiogenesis, and neurogenesis were assessed using immunohistochemistry with antibodies against ionized calcium-binding adapter molecule 1 (Iba-1), rat endothelial cell antigen-1 (RECA-1), and bromodeoxyuridine (BrdU)/doublecortin (DCX), respectively. Results : Our results showed that intravenous MFG-E8 treatment did not reduce the infarct volume; however, the mNSS test revealed that neurobehavioral deficits were significantly improved in the MFG-E8-treated group than in the vehicle group. Immunofluorescence staining revealed a significantly lower number of Iba-1-positive cells and higher number of RECA-1 in the periinfarcted brain region, and significantly higher numbers of BrdU- and DCX-positive cells in the subventricular zone in the MFG-E8-treated group than in the vehicle group. Conclusion : Our findings suggest that MFG-E8 improves neurological function by suppressing inflammation and enhancing angiogenesis and neuronal proliferation in the subacute phase of cerebral infarction.

Clinical and preclinical studies have reported that Lactobacillus gasseri BNR17, a probiotic bacterial strain isolated from human breast milk, reduces body weight and white adipose tissue volume. In order to further explore the actions of L. gasseri BNR17, we investigated the anti-menopausal effects of L. gasseri BNR17 in an ovariectomized (OVX) rat model. The serum alanine aminotransferase levels of the rats in the OVX-BNR17 group were lower than those of the rats in the OVX-vehicle only (OVX-Veh) group. Upon administration of L. gasseri BNR17 after ovariectomy, calcitonin and Serotonin 2A levels increased significantly, whereas serum osteocalcin levels showed a decreasing tendency. Compared to the rats in the OVX-Veh group, those in the OVX-BNR17 group showed lower urine deoxypyridinoline levels, lower pain sensitivity, and improved vaginal cornification. Furthermore, L. gasseri BNR17 administration increased bone mineral density in the rats with OVX-induced femoral bone loss. These results suggest that L. gasseri BNR17 administration could alleviate menopausal symptoms, indicating that this bacterium could be a good functional probiotic for managing the health of older women.

The purposes of this study were to quantify and compare the kind and amount of solid waste generated in two school foodservice operations located in urban and rural areas. A waste stream analysis was conducted to quantify and characterize the kind of waste in the production and service parts of each operation. The SPSS 10.0 for window was used for data analysis. Non-parametric test (Mann-Whitney) was adopted to determine if significant differences exist in amounts of waste generated in the urban school and the rural school. An average of 415 meals, including 43 adult meals, were served daily in the urban school, while an average of 177 meals, including 24 adult meals, were served daily in the rural school. Food waste generated in the production part in the urban school composed approximately 87% and 45%, while that in the rural school composed 71% and 28% by weight and volume, respectively. Waste per meal was not significantly different between the urban school and the rural school in the production part except the cardboard waste. The total waste per meal at lunch was 154g or 465m1 in the urban school and 51g or 334m1 in the rural school. Students in the urban school discarded significantly more food waste and milk than students in the rural school did. The research results suggest that school foodservice dietitians should evaluate the acceptability of menu items based on food waste per meal, and assess the feasibility of implementing a plan for recycling packaging waste and composting organic waste.
