This research was planned and executed to evaluate how the nutritional composition and antioxidants contents and antioxidative activity of Hongsambak. Also, can effect health conditions of people who are suffering from diet-related disease like obesity and hyperlipidemia by taking healthy foods with Hongsambak in a form of nutritional supplement with our daily meals. With this observation, we found out that Hongsambak has high content of dietary fiber and effect on antioxidative activity. We concluded that we could apply the components in a form of various foods. The information we received from this conclusion will be a basic information on how we can apply oriental medicinal resources into other foods and in the field of functional food research, which already draes sizable attention world-wide.

Ten healthy wome 2-~25 years participated in a 5-week metabolic study to investigate the daily riboflavin requirement of Korean women. Three daily menu and meal patterns were used. Low riboflavin(LR) diet provided riboflavin at a level of 0.71mg / 1000Kcal based on food composition table. High riboflavin(HR) diet provided 1.14mg / 1000Kcal. The riboflavin status was assessed by erythrocyte glutathione reductase activity coefficient(EGRAC) and urinary exretion of riboflavin. Mean EGRAC of LR period and HR period were 1.17+0.08 and 1.01+0.03, repectively. There were discrepanices of riboflavin content of experimental diet between chemical analysis and calculation by Korean food composition table. Urinary riboflavin excretion of subjects was acceptable over the whole study period. It appeared that 0.71mg / 1000Kcal is requirement of riboflavin to maintain EGRAC withing normal range. Thus, it is suggested that current recommendation of 0.6mg / 1000Kcal of riboflavin intake may not be adequate as RDA level in Korea.

These experiments were designed to study the influence of early protein undernutrition on growth, behaviors toward food, general attitude toward a new environment, brain size and body composition of the experimental rats. The following experimental groups were studied. Lactation period (3 weeks) (Diets of mother rats) 25% Casein diet 12% Casein diet 25% Casein diet 25% Casein diet 12% Casein diet 12% Casein diet After-weaning protein deprivation period None deprivation (25% Casein diet) None deprivation (25% Casein diet) 5% Casein diet (4 weeks) 5% Casein diet (8 weeks) 5% Casein diet (4 weeks) 5% Casein diet (8 weeks) After a long period of rehabilitation with 25% casein diet the following results were obtained. 1. Growth rate during lactation period is closely related with the protein levels of the diet for mother rats. The average body weight of offsprings of the mother rat fed 25% casein diet is 46.0 grams at 21 days old. However, that of the mother rat fed 12% casein diet is only 25.0 grams. 2. The group of protein undernutrition during lactation (S weeks) (offsprings of mother rat fed low protein diet, 12% casein diet) could never catch up with the normal group in its growth even after twenty-four (24) weeks of rehabilitation. 3. However, the groups of protein undernutrition during either four (4) or even eight (8) weeks after weaning could catch up with the normal group in their growth after long period of rehabilitation. 4. The absolute amounts of carcass protein and fat of the normal group are larger than those of the protein deficient groups. In terms of percent carcass, however, the normal group showed higher body fat and lower body protein than the early deficient groups. However, there is no difference between preweaning (3 weeks) and postweaning (8 weeks) deficient groups. It is assumed, from these differences in body composition, that there might be any differences in physiological and metabolic functions among these various groups, and also that the basic formation of various metabolic regulators (protein-nature) might be fixed mostly during lactation and postweaning period. 5. The groups of protein undernutrition during either three (3) weeks lactation or four (4) weeks after weaning are not so remarkably different from the normal group in their amounts of food intake and spillage. However, the groups of undernutrition during either eight (8) weeks postweaning or eleven (11) weeks (3 weeks lactation period plus 8 weeks postweaning period) showed higher amounts of food intake and spillage. In these respects, it seems that desire for food is closely related with the degree of early hunger in protein and also seems that the longer be deficient in early life the more food spillage is found. 6. Both preweaning and postweaning deficient groups showed generally nervous and restless. The normal group is staid and showed less mobilities. 7. The average size of the brains of the group subjected to protein deficiency during three (3) weeks lactation period is smaller than that of the group of the eight (8) weeks postweaning deficiency. This means that the development of the brain is made mostly during lactation period. The group of the eleven (11) weeks postnatal deficiency is significantly different from the normal group in its brain development. It is assumed, in connection with the results of various maze tests reported, that the brain size is closely related with the intellectual ability.

The research studied the nutritional composition and health effects of the Giwongo with its efficacy in providing nourishment to blood, liver and kidney as well as being an aid to the mental stability. The Giwongo is made by boiling the same amounts of Lycium fructus and Longanae arillus. Giwongo was analyzed to measure proximate nutritional composition, mineral contents, free sugar content and polyphenol compound content. The DPPH scavenging activity and its antioxidative effectiveness were also analyzed. Giwongo was composed of 16.7% water, 4.9% crude protein, 3.7% crude fat, 3.8%, crude ash 70.9% carbohydrate with the content per 100 g of 336.5 kcal. The Giwongo mineral contents were potassium, sodium and calcium in sequence according to contents. Per 100 g Giwongo were found 9.62 g glucose, 4.67 g fructose and 18.00 g sugar. The Giwongo had 60.67% DPPH electron donating ability and $32.19^{\circ}Brix$. The Giwongo made of Lycium fructus and Longanae arillus had effectiveness of tonify the liver and kidney, nourish blood, and psychologic stability. As such Giwongo may help prevent the symptoms of unbalanced health due to excessive stress and unhealthy diet.

The diet composition of Arctoscopus japonicus was studied using 448 specimens collected in the coastal waters of East Sea, Korea. The size of the specimens ranged from 6.2-25.3 cm in total length (TL). A. japonicus were fed mainly on amphipods that constituted 76.1% in IRI. Euphausiids were the second largest prey component. The diets also include small quantities of crabs, copepods, mysids, cephalopods, monogeneans, and fishes. A. japonicus showed ontogenetic changes in feeding habits. Smaller individuals (6-10 cm, TL) fed mainly on amphipods. The proportion of amphipods decreased as body size increased, whereas the consumption of euphausiids gradually increased (10-14 cm, TL). As the body size more increased, the proportion of amphipods increased whereas euphausiids decreased (14-26 cm, TL).

This experiment was conducted for compare domestic experimental microparticulated diets with imported commercial microparticulated diets in olive flounder larvae, Paralichthys olivaceus (Temminck et Schlegel). Fish larve were fed four microparticulated diets from 8th day after hatching. Four diets were two commercial microparticulated diets D and H, and experimental microparticulated diets K1 and K2 formulated each with different protein sources (diet K1 ; squid meal, blood meal, yeast extract, chlorella powder, olive flounder muscle, Lys, and Met ; diet K2 ; whole egg protein, krill meal, short-necked clam meal, squid muscle, live yeast, yeast extract, and casein). There were no significant differences on body weight, body length and survival rates among four diet treatments up to the 40th day after hatching. At the 83th day after hatching, fish fed diet D had a significantly higher survival rate than that of fish fed diet K2, whereas there was no significant difference between to diet H and K1. Fish fed diet D had a significantly higher body weight than these of fish fed diaet K1 and K2, whereas there was no significant difference between fish fed diet D and H. There was no significant difference on EPA and DHA of body fatty acid composition among four diet treatments up to the 83th day after hatching. These results show that nutritionally well-ballanced domestic microparticulated diets for olive flouner lavae can be developed.

This study was conducted to investigate the effect of increasing dietary fat on plasma lipoprotein in young Korean women. During the three weeks of experimental periods, 8 healthy college women consumed a regular diet, a medium fat diet and a high fat diet for one week, consecutively. The percentages of fat from energy intake in the subjects on the regular, medium, and high fat diets were 20, 29 and 38%, respectively. Our data showed that the dietary intakes of fat and cholesterol had an influence on the plasma lipoprotein. The medium fat diet enhanced the blood glucose concentration and the plasma HDL, and the high fat diet resulted in increases in the blood glucose concentration and the plasma LDL as well as HDL. Also the type of diets led to changes in the composition of lipoprotein. When on the medium fat diet, HDL and LDL had higher phospholipid content. On the high fat diet, LDL had higher phospholipid, cholesterol and triglyceride contents, and HDL included higher cholesterol content.
