  • The purpose of this study was to assess nutrient intake and dietary quality in female college students according to their coffee consumption. The survey was conducted through questionnaires and 3-day dietary records with 353 students. The subjects were divided into three groups: students who didn't consume coffee (non-coffee group, N=119), students who consumed <250 ml coffee (light-coffee group, N=140), and students who consumed ${\geq}$250 ml coffee (moderate-coffee group, N=94). There were no significant differences in age, weight, height, and BMI among the three groups. The mean daily energy intake was 1800.8 kcal in the non-coffee group, 1724.9 kcal in the light-coffee group, and 1729.7 kcal in the moderate-coffee group. The moderate-coffee group consumed a significantly higher amount of alcohol than the light-coffee group (p<0.05). The average intakes of dietary fiber, vitamin A, ${\beta}$-carotene, and folate in the non-coffee group were significantly higher than those in the light-coffee and moderate-coffee groups. Indexes of Nutritional Quality (INQ) for vitamin A, niacin, and vitamin B6 were significantly higher in the non-coffee group than in the light-coffee group. Also the non-coffee group consumed a significantly higher amount of vegetables compared to the light-coffee group. There was no significant difference in the Dietary Diversity Scores (DDS) among the three groups. These results suggest that coffee consumption affects food and nutrient intake in female college students.

  • This study was done to evaluate the health and nutritional status of female college students in Seoul. The subjects were 63 healthy college students aged 20 to 29 years. Their body composition, dietary intakes, clinical blood indices were investigated. Their body composition was determined by means of a multifreqency bioelectrical impedance analysis. Their dietary intake was determined using 3-day record method and their nutrient intake was analyzed by Computer Aided Nutritional analysis program for professional (CAN-pro). Their hemoglobin, hematocrit, red blood cell (RBC), white blood cell (WBC) and mean corpuscular volume (MCV) were determined by semi-automated microcell counter (F-520). Their plasma total cholesterol, TG, and HDL-cholesterol levels were measured using test kits. All data were statistically analyzed by SAS PC package program. Their average consumption of calcium, iron vitamin A, vitamin B2 and niacin were 63.3%, 65.0%, 85.2%, 89.2% and 95.2% of RDA, respectively. The overall mean values of the hematological indices in the female college students were within the normal range. However anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (<36%) accounted for about 20% of the subjects. The mean levels of total cholesterol, HDL-cholesterol and TG were 188.4mg/dl, 69.9mg/dl and 67.4mg/dl, respectively. The percentages of the subjects with plasma total cholesterol level (> 200mg/dl) and LDL-cholesterol (>130mg/dl) were about 41% and 30.4%, respectively. The data showed a significantly positive correlation between either body fat (%) or BMI and TG. However. there was a significantly negative correlation between either body fat (%) or BMI and HDL-cholesterol. These overall results suggest that it is necessary for college women to be educated regarding consuming more iron and vitamin C and less fat, in order to prevent iron deficiency anemia and/or cardiovascular diseases in later life.

  • Objectives: Prolactin is vital for breastfeeding and milk production, and its secretion is influenced by factors related to the mother, infant, and environment. To date, no study has concurrently investigated the correlation of these factors with serum prolactin levels during lactation. Therefore, the objective of this study was to investigate the correlations among maternal and infant factors, lead exposure, and serum prolactin levels during lactation. Methods: A cross-sectional approach was employed in Surabaya, Indonesia, among 110 exclusively lactating mothers. The mothers' daily diets were determined using multiple 24-hour recalls, while blood lead levels were measured with inductively coupled plasma mass spectrometry. Serum prolactin levels were assessed using the electrochemiluminescence immunoassay. For bivariate analysis, we employed the Spearman correlation, Mann-Whitney, and Kruskal-Wallis tests, while for multivariate analysis, we utilized multiple linear regression. Results: The average serum prolactin level of the lactating mothers was 129.19±88.96 ng/mL. Positive correlations were found between serum prolactin levels and breastfeeding frequency (p<0.001), protein intake (p<0.001), and calcium intake (p=0.011) but had negative correlation with blood lead levels (p<0.001) and vitamin B6 intake (p=0.003). Additionally, prolactin levels were not significantly associated with maternal age; parity; intake of calories, vitamin D, vitamin E, zinc, folic acid, magnesium, or iron; infant age; or infant sex. Conclusions: Breastfeeding frequency had a stronger positive relationship with serum prolactin levels than protein and calcium intake. However, lead exposure was associated with reduced serum prolactin levels during lactation. Consequently, specific interventions from policymakers are necessary to manage breastfeeding in mothers exposed to lead.

  • The large number of past investigation on extended myocardial protection clearly indicates that cold potassium cardioplegia and topical cooling have limited capabilities. Accordingly, more recent experimen- tal approaches have focused on the modalities of reperfusion and their implication on postischemic myo- cardial recovery. Oxygen may play a crucial role in the development of ischemic and reperfusion injury. Reactive oxygen radicals may be produced during ischemia or reperfusion after incomplete reduction of molecular oxygen or from other pathway and then induce fatal injury of the heart. The important obser- vation of oxygen-induced myocardial damage during reperfusion has led to the concept of applying oxy- gen free radical scavengers. So, this study is on dietary vitamin C supplementation as antioxidant in rats to determine whether or not they have a higher tolerance against cardiac ischemia-reperf'usion injury under Langendorff system. Male or female Sprague-Dawley rats (190-33Og) were randomly separated into two groups. Group A was not treated(n=10). Group B received vitamin C supplement (n=10). Experiment was performed 24 hours after vitamin C 200mg fed orally as injectable ascorbic acid. There were significant differences in contractile parameters between control and vitamin C-treated group. The RLVP (r te of post/preischemic left ventricular pressure) and Rdp/dt (rate of post/preischemic dp/dt) were significant statistically between two groups (p<0.05). But, RHR (rate of post/preischemic heart rate), time to first beat and sta'utilization were not significant. In conclusion, pretreatment with the antioxidant, ascorbic acid, was found to preserve left ventricular contractile function. But the precise mechanism of action of ascorbic acid has not as yet been determined, so further study will be required.

  • The quality and antioxidative characteristics of drinks prepared with different mixing ratios of black garlic and Oenanthe javanica DC., BD-1 (black garlic only), BD-2 (black garlic:Oenanthe javanica DC.=2:1), BD-3 (black garlic:Oenanthe javanica DC.=1:1), and BD-4 (black garlic:Oenanthe javanica DC.=1:2), were studied. The pH increased with the increasing concentration of Oenanthe javanica DC. extract in all the tested drinks, but the sugar contents decreased. The total polyphenol contents of the drinks were 28.48 ${\mu}g/mL$ (BD-1), 41.91 ${\mu}g/mL$ (BD-2), 42.36 ${\mu}g/mL$ (BD-3), and 46.96 ${\mu}g/mL$ (BD-4). The SOD-like activity was highest for BD-4 (18.60%), followed by BD-3 (15.53%), BD-2 (12.53%), and BD-1 (10.27%). The thiobarbituric acid reactive substances (TBARS) was highest for BD-4 (52.51%), followed by BD-3 (45.70%), BD-2 (39.44%), and BD-1 (28.72%). The ferrous ion chelating activity increased with the increasing concentration of Oenanthe javanica DC extract, and BD-4 showed the best activities among all the tested drinks. The water-soluble vitamin content (vitamins B1, B2, B6, and C) of BD-4 (1197.77 ${\mu}g/mL$) was higher than those of the other drinks (BD-1, 213.02 ${\mu}g/mL$; BD-2, 477.87 ${\mu}g/mL$; BD-3, 914.72 ${\mu}g/mL$), and the vitamin C (806.21 ${\mu}g/mL$) content of the water-soluble vitamins at BD-4 was higher than those of vitamins B1 (68.04 ${\mu}g/mL$), B2 (312.51 ${\mu}g/mL$), and B6 (11.01 ${\mu}g/mL$). BD-4 showed the best score in the sensory evaluations, such as in the evaluation of the color, flavor, taste, and overall acceptability.

  • The composition of fatty acids, minerals, total dietary fiber and vitamin $B_1,\;B_2$, in pigmented rice varieties were determined. Proximate composition and color were also compared among pigmented rice varieties. Crude protein contents of black rice were higher than those of red and white rice, especially, C3GHi line had the highest protein content. There were no significant differences in lipid and crude ash contents between pigmented and white rice. Black rice showed lower Hunter value L and b value compared with red, green and white rice. But, Green rice showed lower Hunter value a compared with black rice. Green rice showed the higher contents in total dietary fiber, vitamin $B_1\;and\;B_2$ compared with white and black rice. The major fatty acids of pigmented rice were palmitic acid, oleic acid and linoleic acid. The contents of oleic acid was similar to that of linoleic acid in white rice. Oleic acid contents was lower than linoleic acid in black rice, but higher in red rice. Most mineral contents of pigmented rice except Fe, Zn and Mn were higher than those of white rice. Especially, Green rice had the highest mineral content.

  • The treatments of Tteokgalbi studied were: control (no antioxidants); (T1) ethanol extracts of Bacillus polyfermenticus SCD (5%); (T2) ascorbic acid (0.06%); (T3) ascorbic acid (0.03%) + ethanol extracts of B. polyfermenticus SCD (2.5%). The pH of T1, T2, and T3 samples was significantly (p<0.05) lower than that of the control for up to 3 days of storage. Thereafter T1, T2 and T3 had a significantly higher (p<0.05) pH value than the control during storage. TBA values were significantly lower (p<0.05) in all treated samples relative to the control. The TBA value of the control rapidly increased after 6 days of storage, whereas the TBA values of the test samples did not sharply increase. T3 samples treated with vitamin C and Bacillus polyfermenticus SCD had a higher TBA value than T1 and T2 samples. The VBN values of T1, T2 and T3 sampleswere lower than that of the control (p>0.05). VBN values of the ground pork meat samples significantly increased (p<0.05) with storage time. The total microbial counts of each sample significantly increased with storage time (p<0.05). The $a^*$ values of T1 and T3 samples containing added vitamin C were significantly higher (p<0.05) than that of the control and T2 samples during storage. The $b^*$ value of T2 samples was significantly higher (p<0.05) than that of other ground pork meat products during storage.

  • The purpose of this study was to compare the hematopoietic effects of Angelica gigas, A. sinensis, and A. acutiloba extract (1 g/kg B.W.) on cyclophosphamide-induced (30 mg/kg B.W.) anemic rats. Cyclophosphamide injection group (AG, AS, AA) showed a decrease in weight gain in comparison with the normal group. Compared to the cyclophosphamide-treated control group, oral administration of Angelica gigas extract for 14 days in the normal group significantly prevented body weight loss. The iron level of the A. gigas-administered group was significantly higher than the control groups. The serum vitamin $B_{12}$ level of A. gigas-, A. sinensis-, and A. acutiloba-administered groups was significantly higher than in the control. We suggest that administration of A. gigas, A. sinensis, and A. acutiloba prevents cyclophosphamide-induced anemia by improving hematological value and iron status.

  • The purpose of this study was to examine the comparison of growth development, bone mineral density and nutrient intakes between double income families' preschool children(DIFPC) and full-time housewives' preschool children(FHPC). Subjects were 111 preschool children. Anthropometric characteristics and bone mineral density in right forearm were measured. The questionnaire was composed of health status, life style, dietary behaviors, and dietary intakes and was completed by the children's mothers. The average age of the DIFPC(n=60) was 53.02 months and that of the FHPC(n=51) was 54.80 months. The birth height and weight of the subjects were 50.47㎝ and 3.27㎏ for DIFPC and 50.85㎝ and 3.36㎏ for FHPC, respectively. The average height, weight, % body fat, and obesity index were 108.50㎝, 18.35㎏, 15.35%, 96.71% in DIFPC and 111.46㎝, 19.64㎏, 16.80%, 97.31% in FHPC, respectively. The bone mineral density in forearm of two groups were 0.24g/㎠ in all. The infant feeding method was significantly different between DIFPC and FHPC; 58.9% of DIFPC was fed formula, while 44.4% of FHPC was fed breast milk(p<0.05). Proportions of children for their regular meal were 59.4%, 89.6%, and 61.0% for breakfast, lunch, and dinner, respectively. The major reasons for irregular meal were lack of time and poor appetite for breakfast and snacks for lunch and dinner. Most of the children answered they have snack over once a day, and 60.0% have unbalanced diet. The intakes of energy, calcium, iron, zinc, vitamin A, vitamin B1, niacin, and vitamin C did not meet the Korean RDAs. The intakes of K and vitamin A for DIFPC were significantly higher than those of FHPC(p<0.05, p<0.05). In conclusion, double income families' preschool children more have a low frequency of breast feeding and low intakes of micro nutrients, such as K and vitamin A than full-time housewives' ones.
