Purpose: There is a fair amount of evidence indicating that increased risk of obesity and insulin resistance is associated with postmenopausal state, but can be modulated by diet and exercise. In this study, we explored whether a Pueraria lobata root-based supplement containing Rehmannia glutinosa (PR) and/or aerobic treadmill exercise can modify the metabolic changes associated with estrogen deficiency. Methods: Seventy rats were randomly assigned to the following groups for 8 weeks (n=10 per group): SHAM, sham-operated; PR0, ovariectomized (OVX) control; PR200, OVX with PR200 mg/kg B.W; PR400, OVX with PR400 mg/kg B.W; EPR0, OVX with exercise; EPR200, OVX with exercise and PR200 mg/kg B.W; EPR400, OVX with exercise and PR400 mg/kg B.W. Results: OVX induced significant increases in body weight, food intake, fat mass, LDL-cholesterol, and fasting blood glucose, confirming induction of menopausal symptoms. PR supplementation or exercise significantly suppressed the above mentioned changes through different regulatory elements in adipose tissue: PR supplement upregulated adiponectin gene expression and aerobic exercise upregulated adiponectin and insulin receptor gene expression and a combination of PR supplement and aerobic exercise showed an additive effect on adiponectin gene expression. Conclusion: Taken together, the results of this study suggest that PR supplement has a potential to provide health benefits in OVX rats through leptin and adiponectin secretion. In addition, the data suggest that combination of exercise and PR would have additive effects on metabolic dysfunction associated with estrogen deficiency.

This study aimed to determine the effects of vitamin C and propolis-supplemented feeds on some blood parameters, lipid peroxidation, and activities of some antioxidant enzymes in broilers exposed to oxidative stress. 360 three-day-old broiler chicks (Ross 308) were randomly divided into four treatment groups each containing 90 animals, including six replicate groups for each treatment. The experimental groups were designated for a 3-42 days period as follows: no supplement to basal ration (Control-Group I); supplement of 500 ppm vitamin C and 200 ppm lead (as lead acetate) to basal ration (Group II); supplement of 1 g/kg propolis and 200 ppm lead (as lead acetate) to basal ration (Group III); and supplement of 200 ppm lead (as lead acetate) to basal ration (Group IV). The highest TG level (86.83 mg/dl) was observed in the lead supplemented group; however, the lowest aspartate aminotransferase (SGOT) level (90.71 IU/L) was observed in the control group (p<0.05). The addition of lead increased the plasma malondialdehyde (MDA) level (p<0.01) compared to other treatments. However, the addition of vitamin C and propolis decreased the plasma MDA level close to control levels. The highest erythrocyte superoxide dismutase (SOD) activity was observed in the lead addition group (p<0.01) while no significant differences were observed for SOD activities of the control, vitamin C +lead, and propolis+lead groups. The plasma reduced glutathione (GSH) activity of the control ($2.30{\mu}mol$/ml) was significantly lower than the lead administered group ($6.20{\mu}mol$/ml) (p<0.01); while this parameter was determined to be similar to other groups. No significant differences were observed between groups for liver GSH activity, but heart GSH activity of the control was significantly higher in comparison to other treatments (p<0.05). To obtain similar antioxidant effects, it is recommend that using propolis (1 g/kg) and vitamin C (500 mg/kg) supplementation in broiler diets may overcome the adverse effects of oxidative stress originating from dietary lead.

This study was conducted to evaluate the effectiveness and preferences of supplementary drinks for very old subjects who are likely to be malnourished. Twenty- five elderly subjects were divided into two groups. The supplemented group(N=15) received 500mls of nutrient supplement(New Care) two times daily for 4 weeks. This resulted in a significant increase in the total calories, protein, minerals and vitamins. Nutritional status was assessed both anthropometrically and biochemically, before and after the study period. A significant improvement in mid arm circumference, triceps skinfold thickness and serum albumin were observed in the supplemented group but not in the control group. There is a possibility that most of the elderly were in an anemic state at the beginning of the study since their mean hematologic parameters were within the lower normal range while their mean serum osmolarities was slightly higher than normal, . Although mean serum hemoglobin and hematocrit were not increased significantly, th percentage of the recovery rate from anemia in the supplemented group was higher than in the control group. Total lymphocyte count also showed similar tendency. Sensory evaluation of nutritional supplementary drinks were relatively good and the elderly showed great interest in nutrient supplements. This study suggests that a nutritional status of poorly nourished elderly subjects can be improved by providing them with nutritional supplementations.

This study was performed to investigate the dietary supplement use and related factors by college students attending in web class. One thousand four hundred college students(male: 632, female: 768) were participated in this study. The questionnaire about dietary supplements use, demographic characteristics, eating behavior, health-related lifestyles, nutrient intake was self-administered and the data were obtained via internet or mail. Dietary supplements were taken by 63.6%(male : 62.2%, female : 64.2%) of subjects. The higher concern about nutrition and health, the higher the incidence of dietary supplements taking was(p < 0.05). Dietary supplement users were satisfied more than non-users about meal served(p < 0.05). Supplements used by most male students were lactic acid beverage, Chinese medicine, geigogi geisoju and multivitamin, Chinese medicine, fiber-processed flood for female students. Most of dietary supplement users answered that the sources of information on supplements were 'friend, family or relatives' and 'TV or radio'. Dietary supplement users were taking significantly more nutrients compared to non-use. Therefore, it may be necessary to provide nutrition information and education which show that balanced diet is the best nutritional strategy for health promotion and diet supplements can be helpful in deficient state nutrients.

Purpose: The aim of this study was to determine the effects of nutritional supplements on periodontal health and tooth mobility after surgery. Methods: Patients were randomly assigned to an intervention group who consumed nutritional supplement drinks for 8 weeks, while the placebo group did not receive any such supplements. The gingival index (GI) and tooth mobility were measured at baseline and at 1, 4, and 8 weeks. In addition, the oral health impact profile-14 and anthropometric measurements along with loss of appetite and dietary intake were assessed at baseline and 8 weeks. Results: At 1 week, GI values were reduced in the intervention group (P<0.05), and tooth mobility had increased, but to a lesser extent in the intervention group (P<0.05). At 8 weeks, the intakes of protein, vitamins A and B1, and niacin were increased in the intervention group. Conclusions: These results demonstrate that nutritional supplementation improves early periodontal healing after surgery.

Single cell of an indigenous phototrophic bacterium, Rhodovulum sulfidophilum, was incorporated in commercial fish feed for Oreochromis niloticus. The bacterial cell was analyzed for nutritional value and tested for toxicity and acceptability as an aquaculture feed supplement. The results showed higher survival rate and significantly higher growth rate (p<0.001) in O. niloticus fed with the bacteria incorporated fish feed. It is suggested that R sulfidophilum can be utilized as an aquaculture feed supplement.

BACKGROUND/OBJECTIVES: Inadequate nutrition in infants and young children affects physical growth and neurocognitive development. Therefore, early nutritional intervention is important to promote catch-up growth in young children with faltering growth. The aim of this study was to evaluate the effect of nutritional supplementation with a pediatric concentrated and balanced nutritional supplement formula on promoting growth and improving nutritional status in children with nonorganic faltering growth. SUBJECTS/METHODS: Children aged 12-36 months whose body weight-for-age was < 5^th percentile on the Korean Growth Charts were enrolled. Children born premature or having organic diseases were excluded. Children were instructed to consume 400 mL of formula per day in addition to their regular diet for 6 months. Pediatricians and dietitians educated the parents and examined the subjects every 2 months. Anthropometric parameters were measured at baseline and at 2, 4, and 6 months, and laboratory tests were done at baseline and 6 months. The good consumption group included children who consumed ≥ 60% of the recommended dose of formula. RESULTS: Total 82 children completed the 6-month intervention. At baseline, there were no significant differences in all variables between the good consumption and poor consumption groups. Weight and weight z-scores were significantly improved in the good consumption group compared to the poor consumption group at the end of the intervention (P = 0.009, respectively). The good consumption group showed a significant trend for gaining weight (P < 0.05) and weight z-score (P < 0.05) compared to the poor consumption group during 6 months of formula intake. The concentration of blood urea nitrogen was significantly increased in the good consumption group (P = 0.001). CONCLUSIONS: Nutritional supplementation with a concentrated and balanced pediatric nutritional formula along with dietary education might be an effective approach to promote catch-up growth in children with nonorganic faltering growth.

The purpose of this study was to assess the biochemical nutritional status of the long-lived elderly. The subjects of the study were 148 elderly people of age over 85 years living in Kyungpook Sung-Ju area who have no problem in daily living. The anthropometric measurement and biochemical assessment of the blood sample were carried out. The subject group for this study was composed of 25.9% males and 74.1% females, the average age being 87 years old. The mean Body Mass Index(BMI) of the male and female subjects were 20.7 and 21.2 respectively. The average body fat amounts of the male and female were 21.4% and 29.8% respectively, and the average waist/hip ratios were 0.9 and 0.7 respectively. The mean levels of the total blood protein and albumin of the subjects were in the normal ranges. The mean levels of serum cholesterol and triglyceride were 167.9mg /dL and 123.9mg/dL respectively. The mean levels of the subjects below normal range of hemoglobin were 63.5%. Serum levels of antioxidant nutrients were very poor. The mean levels of serum lipid peroxidation products were 3.3nmol/mL. BMI and WHR were positively correlated with the serum cholesterol levels. The resuts showed that the long-lived elderly had good nutritional status except for antioxidant nutrients status. In addition antioxidant supplement for long-lived elderly may be effective to maintain healthy life in later years.

This study was performed to investigate nutritional intakes and preference food and blood composition of female college students of premenstrual syndrome. Based on physical measurement test results, both groups showed no noticeable difference and both groups were within the normal range according to body composition analysis. In terms of nutrients consumption, results showed nutritional intakes more than EAR(estimated average requirements) included phosphorus>vitamin $B_6$>vitamin $B_1$, while nutritional intakes less than EAR were vitamin A>vitamin $B_6$>calcium>folic acid. A significant difference was observed for vitamin C intake(p<0.05). The overall mean values of basic blood(WBC, RBC, Hct, and Hb), sex hormone(Estrogen, Progesterone), aldosterone, cortisol, Cu, Zn, and Ca, Mg indices in female college students were within the normal range and there was no significant difference between the PMS group and the Normal group. In conclusion, vitamin C intake of the PMS group showed a level of 84.8% EAR. Therefore vitamin C supplement can be beneficial to relieve the PMS Syndrome.

Young goats were fed low quality roughage ad libitum and supplements of insect-damaged Lablab purpureus (var. Highworth) seed fed at approximately 3, 6 or 12 g/kg liveweight (LW), or sweet lupin seed (Lupinus angustifolius var. Uniharvest) fed at 12 g/kg LW. Roughage intake was not changed by 3 or 6 g/kg LW levels of Lablab or by 12 g/kg LW lupin supplement, but was reduced (p<0.05) by 35% by 12 g/kg LW Lablab supplement. Organic matter (OM) digestibility was increased by all supplements, and digestible OM intake was increased by the 6 g/kg LW Lablab and 12 g/kg LW lupin supplements. LW gain and feed conversion ratio were not changed by 3 or 6 g/kg LW Lablab or the 12 g/kg LW lupin, but were reduced (p<0.05) by 12 g/kg LW Lablab supplement. It was concluded that young goats could efficiently utilize supplements of Lablab purpureus seed fed at levels of up to 6 g/kg LW. However, when 12 g/kg of the Lablab seed was fed, poor performance suggested that the goats were adversely affected by anti-nutritional factors which were not neutralized by rumen fermentation.
