Objective: Astaxanthin is a natural super antioxidant. The present study was carried out to investigate the effect of astaxanthin rich Phaffia rhodozyma (PR) supplementation in diets on laying production performance, egg quality, antioxidant defenses and immune defenses in laying hens. Methods: A total of five hundred and twelve 60-week-old Lohmann Brown laying hens (2,243±12 g) were randomly assigned to four groups, each including 4 replicates with 32 birds per replicate. Astaxanthin rich PR was added to corn-soybean meal diets to produce experimental diets containing 0 (Control), 800 mg/kg, 1,200 mg/kg, and 1,600 mg/kg PR, respectively. The astaxanthin content in the diet was 0.96 mg/kg, 1.44 mg/kg and 1.92 mg/kg respectively. Results: Results showed that dietary PR supplementation tended to increase daily feed intake (p = 0.0512). There was no effect of astaxanthin rich PR on Haugh units, albumen height, egg shape index, eggshell strength, and eggshell thickness at weeks 6 (p>0.05). However, egg yolk color was significantly improved (p<0.05). In addition, astaxanthin rich PR supplementation significantly increased serum glutathione peroxidase and superoxide dismutase activity (p<0.05), increased serum immunoglobulin G content (p<0.05), and reduced malondialdehyde content (p<0.05) in laying hens. Conclusion: In conclusion, astaxanthin rich PR can improve the color of egg yolk, enhance the antioxidant defenses, and regulate the immune function.

The purposes of the study were to analyze nutritional status, psychosocial stimulation, and factors affecting the cognitive development of preschool-age children. This study was conducted in the Village of Babakan, Sub-District of Dramaga, Bogor Regency, West Java. This cross-sectionally designed study was conducted with mothers who had preschool children aged 3-5 years as respondents. Fifty-eight children were included. The distribution of mother's educational level was quite diverse, and the largest percentage (44.8%) had senior high school education. Approximately 78% of the family income per capita was classified into the non-poor category and 22.4% into the poor category. The average mother's nutritional knowledge score was $76.7{\pm}2.5$ (moderate category). Most of the preschool children (84.4%) had psychosocial stimulation scores in the moderate category (30-45). The nutritional status of children showed that 15.5% were underweight, 5.2% were wasted, 3.4% were severely wasted, and 19% of the children were in the short and very short categories (stunted). The stepwise regression results showed that psychosocial stimulation (P < 0.001), participation in early childhood education (P = 0.002) and nutritional status based on the height index for age (P = 0.028) had a positive and significant effect on cognitive development of the preschool children (adjusted $R^2$, 0.434; P = 0.028).

This study was performed to investigate the effect of family type on the nutrient intake and nutritional status in elderly women. Blood samples and anthropometric data of elderly women aged from 60 to 78 years were collected in 1996, who visited a health examination center in Seoul to screen their health status. They were divided into two groups by their family type, one was extended family(extended family elderly, n=37) and the other was independently living(independently living, n=29). Nutrients intake was measured by interview using a simplified questionaire. Albumin, cholesterol, triglyceride(TG), hemoglobin (Hb), hematocrit, Ca, Mg, and alkaline phosphatase activity of serum were analyzed. Intakes of energy, protein, carbohydrate, Fe, vitamin A, niacin, thiamin, riboflavin, and vitamin C were not different between the two groups. However, fat and Ca intakes were higher(p<0.05) in extended family elderly than indepen dently living elderly. There are no significant difference in hematocrit value and serum concentrations of Hb, TG, and Ca. Serum Mg and cholesterol levels tended to be higher in extended family elderly. However, serum albumin level was lower(p<0.05) in extended family elderly. These results show that the indepen dently living elderly women had intakes of daily energy, fat and Ca compared to the extended family elderly. Therefore, the nutritional education for the independently living elderly will be focused on the health risk resulted from less intakes of Ca and total energy.

Soybean sprouts are the third-most consumed vegetable in Korea. Several studies on cultivation techniques, including use of medicinal plants extracts, have been performed to enhance the quality and yield of soybean sprouts. The objective of the present study was to investigate the effect of lacquer, a medicinal plant extract, on the yield and nutritional value of soybean sprouts. Linolenic acid content was significantly (p<0.05) increased in the sprouts produced by soaking seeds in lacquer extract diluted with equal volume of water. Lacquer extract significantly increased the flavonoid and phenolic contents (p<0.05). The content of total free amino acids, including ${\gamma}$-aminobutyric acid, was higher in lacquer extract-treated sprouts than in the untreated control. Results of this study suggest that lacquer extract could be used for enhancing the yield and nutritional values of soybean sprouts.

This study was performed to investigate the effect of chlorella on cadmium (Cd) toxicity in Cd-administered rats. Sixty male Sprague-Dawley rats (14 week-old) were blocked into 6 groups. Cadmium chloride was given at levels of 0 or 325 mg (Cd: 0, 160 ppm), and chlorella powder at levels of 0, 3 and 5%. Cadmium was accumulated in blood and tissues (liver, kidney and small intestine) in the Cd-exposed groups, while the accumulation of Cd was decreased in the Cd-exposed chlorella groups. Fecal and urinary Cd excretions were remarkably increased in Cd-exposed chlorella groups. Thus, cadmium retention ratio and absorption rate were decreased in the Cd exposed chlorella groups. Urinary and serum creatinine, and creatinine clearance were not changed in experimental animals. In addition, metallothionein (MT) synthesis in tissues was increased by Cd administration. The Cd-exposed chlorella groups indicated lower MT concentration compared to the Cd-exposed groups. Moreover, glomerular filtration rate (GFR) was not changed by dietary chI orella and Cd administration. According to the results above, this study could suggest that Cd toxicity can be alleviated by increasing Cd excretion through feces. Therefore, when exposed to Cd, chlorella is an appropriate source which counteracts heavy metal poisoning, to decrease the damage of tissues by decreasing cadmium absorption.

This study was performed to investigate the effectiveness of nutritional education and exercise intervention on reduction and maintenance of weight. The subjects were 24 obese women whose body mass index(BMI) was over $25kg/m^2$. Nutritional education was performed once a week and swimming was done three times a week throughout this 12 week program. The subjects were recalled 1 month after the program was complete. Nutrient intakes were assessed by 24 hour recall method. Also food habits, dietary behaviors and nutritional knowledge were investigated by self-administered questionnaires before and after the weight control program and one month after completing the program. Height, weight, body composition and blood levels were measured before and after the weight control program and one month after completing the program. During the 12 weeks of the weight control program, body weight significantly decreased from an average of 69.7kg to 65.8kg and to 65.1kg after one month(p<0.05). Body fat and BMI also significantly decreased(p<0.01). Cholesterol and blood sugar levels decreased after 12 weeks and increased one month after completing the program. After taking nutritional education, the nutritional knowledge scores increased. Calcium intake significantly increased after completing the education and one month after completing the program(p<0.01). Iron intake significantly decreased from an average of 12.1g to 11.3g after completing the program and increased to 15.5g one month after completing the progrom(p<0.001). We concluded that our nutritional education and exercise program was effective for reducing and maintaining weight.
