How to appropriately apply the theories of oriental diet therapy in terms of direction and development are pressing concerns. To address these concerns, this study was performed to provide basic ideas to further the understanding oriental medicinal cuisine(Yack-Sun) and aid its application. Presently, basic data on the nutritional composition and oriental diet therapy area approach of Reajerksodo-tang was acquired to predict the usefulness of Reajerksodo-tang as an edema-related diuretic to promotes urination, drains heat and leaches out dampness. Reajerksodo-tang energy was 67.3 kcal per 100 g, crude protein was 77.2 g, crude fat was 5.7 g, crude ash was 0.6 g and carbohydrate was 16.5 g per 100 g. This basic data could help guide the application of oriental medicinal resources into other foods and serve as a stepping-stone for use of Reajerksodo-tang in the burgeoning field of function foods. Lastly, the scientific effects of oriental medicinal foods developed according to oriental medicinal theory. It is believed to be essential for government policy development concerning validation of medicinal effects and assessment, with the aim of fostering systematic development and providing guidance to food development in the interest of national health.

The objective of this study was to examine the effects of a fruit diet and exercise on body composition and hematological parameters in female collegians according to their uncoupling protein 2 (UCP2) genotypes. Nine subjects were recruited from the SahmYook University. 4 subjects carried the ID genotype, 5 the DD genotype, and none of the subjects carried the II genotype. After 10 days of the program, BMI were significantly decreased (p<0.05) in the ID genotype and the DD genotype. Mean total energy intake from fruit diet was 888.1 kcal. Fat mass and % body fat were significantly decreased (p<0.05) in subjects with the ID genotype. Hemoglobin level was significantly increased (p<0.05) in subjects with the DD genotype. This study provided evidence that fruit diet and exercise could decrease the BMI in subjects with the ID and DD genotypes and increase the hemoglobin level in those with the DD genotype.

The purpose of this study was to see the effect of oral administration of reserpine (2mg/d) and tryptophan (40.35mg/d) on the serum amino acid concentrations and organ composition, food consumption, body weight, blood hematocrit(Hct) and hemoglobin(Hb) levels in Sprague-Dawley rats fed 6% or 20% casein diet. Any adverse effects of reserpine and tryptophan were not observed in animals, except that liver fat contents were increased in low protein group. In other words the administration of typtophan decreased liver fat contents in 6% casein and reserpine-treated 20% casein groups, but increased in reserpine-treated 6% casein group. But the low protein diet had significant adverse effects in animals. The 6% casein diet, therefore, had a tendency to decrease food consumption and body weight. The simillar tendency was shown in serum essential amino acid concentrations, organ weight and protein contents of liver and muscle. From the results, it would be safe to conclude that the oral administration of large deses of reserpine and tryptophan did not induce such a signifcant malnutrition as the low protein diet did.

The diet composition of Takifugu niphobles was studied with 587 specimens collected in the eelgrass bed of Jangpyeong-ri, Tongyeong, Korea, using a seine net, monthly from May 2016 to April 2017. The standard length (SL) of the specimens ranged from 0.7 to 9.0 cm. The stomach contents analysis indicated that T. niphobles consumed mainly amphipods (%IRI: 91.0 %). In addition, T. niphobles fed on small quantities of copepods, polychaetes, insects, bivalves and crabs. T. niphobles consumed mainly amphipods over all size class. Smaller individuals (less than 4 cm SL) fed mainly on amphipods and copepods. The proportion of copepods decreased, as body size increased, whereas the consumption of polychaetes increased gradually. The seasonal variation in the diet composition of T. niphobles was significant. Amphipods were most common prey in all seasons. Copepods decreased from summer to spring gradually whereas the consumption of polychaetes increased in autumn.

To understand the formation of initial gut microbiota, three initial fecal samples were collected from two groups of two breast milk-fed (BM1) and seven formula milk-fed (FM1) infants, and the compositional changes in gut microbiota were determined using metagenomics. Compositional change analysis during week one showed that Bifidobacterium increased from the first to the third fecal samples in the BM1 group (1.3% to 35.1%), while Klebsiella and Serratia were detected in the third fecal sample of the FM1 group (4.4% and 34.2%, respectively), suggesting the beneficial effect of breast milk intake. To further understand the compositional changes during progression from infancy to childhood (i.e., from three weeks to five years of age), additional fecal samples were collected from four groups of two breast milk-fed infants (BM2), one formula milk-fed toddler (FM2), three weaning food-fed toddlers (WF), and three solid food-fed children (SF). Subsequent compositional change analysis and principal coordinates analysis (PCoA) revealed that the composition of the gut microbiota changed from an infant-like composition to an adult-like one in conjunction with dietary changes. Interestingly, overall gut microbiota composition analyses during the period of progression from infancy to childhood suggested increasing complexity of gut microbiota as well as emergence of a new species of bacteria capable of digesting complex carbohydrates in WF and SF groups, substantiating that diet type is a key factor in determining the composition of gut microbiota. Consequently, this study may be useful as a guide to understanding the development of initial gut microbiota based on diet.

The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen. The groups were assigned to receive treatment diets as follows: i) basal diet (control), ii) basal diet plus 0.5% garlic powder (GP), iii) basal diet plus 0.5% pennywort powder (PW) and iv) 0.002% virginiamycin (VM). Birds were killed at day 42 and intestinal samples were collected to assess for Lactobacillus and Escherichia coli. The pectoralis profundus from chicken breast samples was obtained from 10 birds from each treatment group on day 42 and frozen at $-20^{\circ}C$ for further analyses. Fatty acid profile of breast muscles was determined using gas liquid chromatography. Feed intake and weight gain of broilers fed with GP, PW, and VM were significantly higher (p<0.05) compared to control. Feeding chicks GP, PW, and VM significantly reduced Escherichia coli count (p<0.05) while Lactobacillus spp count were significantly higher (p<0.05) in the gut when compared to control group on day 42. Supplemented diet containing pennywort increased the C18:3n-3 fatty acid composition of chickens' breast muscle. Garlic and pennywort may be useful in modulating broiler guts as they control the enteropathogens that help to utilize feed efficiently. This subsequently enhances the growth performances of broiler chickens.

The CLA used to add in diet was chemically synthesized by alkaline isomerization method with corn oil. To investigated the effects of conjugated linoleic acid(CLA) added diet feeding on CLA accumulation and blood characteristics of pork, a total of 64 Landrace was fed both CLA-free and CLA-added(0.3, 0.6 and 0.9%) diet for 1∼4 weeks. Cholesterol compositions in blood and CLA contents and fatty acid compositions of loin, belly, bone and skin were determined at 1, 2, 3 and 4 weeks after CLA added at fed. The HDL content in blood of all treatments was higher(P<0.05) than that of control and that of treatment 3 was higher(P<0.05) than that of other treatments among the CLA feeding periods. Palmitic, stearic and linolenic acids composition of loin and belly was increased but oleic, linoleic and arachidonic acids composition of them was decreased according to increasing the CLA feeding periods. CLA contents of loin and belly were higher than that of control and increased according to increasing the quantity of CLA and CLA feeding periods. CLA contents of bone and skin were higher than that of control, too. CLA content of skin was higher than that of bone. It was suggested that CLA could be accumulated in loin, belly, bone and skin by dietary CLA supplementation, and the CLA concentration and fatty acid composition in muscle could be affected by CLA level in diet and feeding period.

The diet composition of octopus Octopus vulgaris was studied using 392 specimens collected from January to December 2020 in the coastal waters of Yeosu, Korea. The body weight ranged from 86.4 to 3,645.4 g. The most important prey item in the diet of O. vulgaris was decapods, which constituted 43.9% in ranking index (%RI). The second largest prey item was Pisces (%RI=27.9%), and cephalopods (%RI=21.8%) constituted the third largest prey item. The average trophic level of O. vulgaris was 3.97±0.59. Ontogenetic changes were significant among size classes (<400 g, 400-800 g, ≥800 g). The small size class (<400 g) mainly fed on decapods, whereas the medium (400-800 g) and large size (≥800 g) classes mainly fed on cephalopods and Pisces, respectively. The dietary composition varied significantly with season.

To investigate the effect of dietary docosahexaenoic acid(DHA) and environmental enrichment on brain fatty acid composition and acetylcholinesterase(AChE) activity, two groups of was fed isocaloric diets containing 10 or 12% dietary lipids for 7 weeks. A third group was fed 10% (w/w) dietary lipids with supplemented 2% DHA-rich fish oil. Each diet group was housed either in a stainless steel cage individually or in a large enriched cage with toys where 7 rats were kept together. The fatty acid composition of plasma and brain was significantly affected by dietary lipid composition but not by environmental enrichment. Fish oil supplementation significanlty decreased plasma levels of monounsaturated fatty acids(MUFA) and increased polyunsaturated fatty acids(PUFA). Fish oil supplemented groups also maintained lower plasma n-6 fatty acids and higher n-3 fatty acids levels than unsupplemented groups. The fish oil supplementation significantly decreased arachidonic acid and increased eicosapentaenic, docosapentaenoic acids, and DHA in brain fatty acid composition. In addition, brain DHA level in supplemented groups tended higher than the unsupplemented. Brain, AChE activity significantly increased by the environmental enrichment but not by the fish oil supplementation. These finding suggest that the 2% fish oil (0.57% DHA & 0.31% EPA, per diet weigth) supplementation is enough to accumulate n-3 fatty acids and to change the n-6 n-3 ratio in brain and environmental enrichment might promote the learning ability.

Effect of dietary nutrient composition on growth and body composition of juvenile olive flounder Paralichthys olivaceus with different feeding strategy was determined. Twenty-five fish averaging 16 g were randomly distributed into 12, 180 L flow-through tank each. Four treatments in triplicates were prepared: fish were fed to satiation twice daily by the control diet for 8 weeks as the control group (Con) and fish were fed to satiation twice daily by the control and high nutrient diets for 6 weeks after 2-week fasting (2WS-6WFC, 2WS-6WFHN, respectively) and finally, fish were fed to satiation twice daily by the high nutrient diet for the consecutive 3 days after 4-day fasting for 8 weeks (4DS-3DFHN). No significant difference was found in either survival or weight gain of flounder among treatments. Feed efficiency ratio (FER) for fish in the 2WS-6WFHN treatment was significantly higher than that for fish in the Con and 2WS-6WFC treatments. Protein efficiency ratio (PER) of fish in the 2WS-6WFHN and 4DS-3DFHN treatments was significantly higher than that of fish in the 2WS-6WFC treatment. In conclusion, manipulation of dietary nutrient composition and/or feeding strategy can effectively improve growth of juvenile olive flounder without growth retardation at restricted feeding regime.
