Effects of cheungho aqua-acupuncture at gansoo$(BL_{18})$ and illweul$(GB_{14})$ on plasma lipid composition were investigated in rat fed high fat diet. Body weight gain showed a tendency to decrease in aqua-acupuncture groups and in aqua-acupuncture groups, gansoo and illweul join aqua-acupuncture group showed a lower values than other aqua-acupuncture groups. Concentrations of plasma triglyceride, free fatty acids, lipoprotein and glucose showed a tendency to decreasea in the aqua-acupuncture groups. However in aqua-acupuncture groups, these values showed no significantly different. In plasma lipid composition, total cholesterol and LDL- cholesterol showed a tendency to decrease in aqua-acupuncture groups, however the values of LDL-cholesterol showed no significantly different in the aqua-acupuncture groups. HDL-cholesterol concentration showed a tendency to increase in aqua-acupuncture groups and in aqua-acupuncture groups, gansoo aqua-acupuncture group showed a high value.

The membrane fatty acid composition of tumor cell can be modified either in cell by altering the lipid composition of the medium of during growth in animals by changing the dietaty fat composition. These modifications are associated with changes in membrane physical properties and certain cellular functions, including carrier-mediated transport and enzyme contained within the membrane. Such effects influence the transport of nutrients and chemotherapeutic agents in cancer cells .Fatty acid modification also can enhance the sensitivity of the neoplastic cell to chemotherapy. The alteration in plasma membrane composition will be affected through dietary supplementations and the potential value to cancer patients could be a better understanding of the effects of diet on responsiveness of neoplasms to chemotherapy, i.e. cancer patients' chances for a "cure" can be improved by diet changes prior to treatment.

This study was conducted to investigate the effect of dietary bee venom on serum characteristics, antioxidant activity, and hepatic fatty acid composition in broiler chickens. A group of 875 one-day-old feather-sexed male broiler chicks were randomly allocated to five treatments with seven replicates (25 birds/replicate) for three weeks. A corn-soybean meal-based diet was used as the basal diet. Five dietary treatments were compared: 1) basal diet, 2) basal diet containing $10{\mu}g/kg$ of bee venom powder, 3) basal diet containing $50{\mu}g/kg$ of bee venom powder, 4) basal diet containing $100{\mu}g/kg$ of bee venom powder, and 5) basal diet containing $500{\mu}g/kg$ of bee venom powder. At 21 days, one bird per pen was slaughtered by asphyxiation in $CO_2$ gas, and blood was collected to measure serum characteristics and antioxidant activity. In addition, the liver was excised to measure the concentration of malondialdehyde and determine fatty acid composition. Increasing dietary bee venom in the diet failed to affect most serum parameters except for triglyceride and non-esterified fatty acids. Dietary bee venom inclusion quadratically increased the concentration of stearic acid (P<0.05), but decreased palmitoleic acid, oleic acid, linoleic acid, mono-unsaturated fatty acids, and poly-unsaturated fatty acids. Finally, dietary bee venom tended to lower hepatic malondialdehyde contents quadratically (P=0.054). In conclusion, our study revealed that dietary bee venom improved antioxidant capacity and affected fatty acid metabolism in broiler chickens.

This study investigated the effects of feeding mulberry leaf extracts on lipid composition in rats fed high cholesterol diets. An initial 30-person sensory evaluation of preparations containing various concentrations of mulberry leaf extract showed that a preparation containing 9% mulberry leaf extracts was the most highly preferred. In addition, subsidiary materials of pine needle extracts and mugwort extracts were added to weaken the unpleasant smell of mulberry leaf extract A preparation containing 9% mulberry leaf extract with 3% mugwort extract and 7% pine needle extract was given highest preference scores by the 30-person panel. When comparing the functional ingredients contents of the various preparations of mulberry leaf extracts, such as GABA, DNJ and flavonoids, no significant differences were found as a result of adding subsidiary materials (pine needle and mugwort extracts). Sprague-Dawley male rats weighing l00$\pm$10g were randomly assigned to one normal diet group, and to four high cholesterol diet groups containing 1% cholesterol, to elucidate the functionality of the mulberry leaf extract The four high cholesterol diet groups were classified into: a mulberry leaf extract diet group free of subsidiary materials (EB group); a mulberry extract diet group with pine needle extracts (EP group); a mulberry leaf extract diet group with mugwort extracts (EM group); and a control group (HC group). The mulberry leaf extracts were provided as drinking water; the diet and water were fed ad libitum. Hepatic cholesterol and triglyceride levels were higher, by 279% to 475%, in the high cholesterol groups compared to the normal diet groups, but were significantly lower in the three groups supplied with mulberry leaf extracts, compared with the high cholesterol control. There were no changes in functionality of the mulberry leaf extract preparations due to the addition of subsidiary materials. In conclusion, preparations of mulberry leaf extracts were shown to improve lipid metabolism in rats fed a high cholesterol diet, by reducing hepatic and plasma triglyceride and cholesterol levels. Also human palatability of the mulberry leaf preparation was improved by adding subsidiary materials such as pine needle and mugwort extracts.

In this study, 230 female college students in Seoul area were surveyed to evaluate their eating habits and behavior, physical activities, and patterns of purchasing diet/low-calorie food. Their body composition was also determined using bioelectrical impedance(Inbody 520). The subjects were divided into two groups according to their BMI index with a mean BMI of 20.2$\pm$1.5(normal) weight and 25.0$\pm$1.7(obesity). Overall, 85.7% of the subjects reported that the food they purchase depends more on their preferences than the nutritional value of the food. When the two groups were compared there was no significant difference in the frequency or experience of purchasing diet-foods. Indeed, 69.3% of all female college students had purchased diet foods, and most consumed these foods 2~3 times a week. Obese group preferred a savory taste, while normal group preferred a sweet taste. The majority of the subjects(80.8%) answered that they "read nutritional labels carefully upon purchasing diet food", and that they examined calories(61.8%) and total fat(48.5%) most carefully. Of the types of low-calorie/diet foods purchased, beverages were the most commonly obtained; followed by noodles, diet-bars, and snacks. The most commonly purchased low calorie snacks were "potato-type C(hot-flavor)" and "potato-type A(salty-flavor)", while the most commonly purchased diet-bars were "low calorie-type A"(55.3%) and "high protein-bar"(32.3%). The most commonly purchased noodles were "thick noodle type"(65.1%), while the most commonly purchased drinks were "cereal tea"(65.1%) and "mixed herb tea"(66.0%). Overall, factors such as self-esteem or the degree of body satisfaction, rather than obesity(BMI index) itself, were significantly correlated with the frequency of purchasing diet-foods.

This study was designed to observe the effects of the feeding of Hijikia fusiforme(Harvey) Okamura juice extract on the improvement of lipids in the serum of cholesterol-supplemented diet induced dietary hyperlipidemic rats fed experimental diets for 4 weeks. Concentration of total cholesterol and LDL-choloesterol in serum was significantly lower in the Hijikia fusiforme juice extract group than in the cholestero diet group. Concentration of HDL-cholesterol in serum was higher in the Hijikia fusiforme juice extract group than the cholesterol supplemented diet group. Those in the Hijikia fusiforme juice extract group were higher than those in the cholesterol diet group. In the ration of HDL-cholesterol concentration to total cholesterol concentration, Hijikia fusiforme juice extract administration group was higher percentage than the other groups. Atherosclerotic index was lower in the Hijikia fusiforme juice extract group than in the cholesterol diet group. Concentration of free cholesterol and cholesteryl ester in serum was rather lower in the Hijikia fusiforme juice extract group than the other groups. Triglyceride concentration in serum was significantly lower in the Hijikia fusiforme juice extract group than in the cholesterol diet group. Concentration of phospholipid in serum was more decreased in the Hijikia fusiforme juice extract group than in the cholesterol diet group. The activities of aspartate aminotransferase and alanine aminotransferase in serum were rather lower in the Hijikia fusiforme juice extract group than the cholesterol supplemented diet group. From the avove research, the Hijikia fusiforme juice extracts were effective on the improvement of the lipid compositions in serum of high fat diet induced dietary hyperlipidemic rats.

The composition of the Martes flavigula diet has been extensively studied, but little is known about its insect component. This study characterized the insect diet and insect nest materials in the feces of M. flavigula. A total of 952 fecal samples were collected in Jirisan National Park from January 2009 to November 2011, and 1379 species or taxonomic groups were identified. M. flavigula fed on insects (8.7%) and bee wax (5.0%), which comprised 2.9% and 4.4% of the dry weight of M. flavigula feces, respectively. A total of 12 insect species belonging to 8 families in 3 orders were identified. The most frequently found insects were Hymenoptera (frequency of occurrence, FO, 89.1), including Vespa simillima simillima (FO, 37.3) and Vespula koreensis koreensis (FO, 20.0). The Vespidae constituted the majority of the insect diet in autumn when the diversity of marten's prey was strongly reduced, probably because the numbers of social insects were sufficient for M. flavigula. In addition, the data suggest that M. flavigula attacks the nests of social wasps in late autumn when males do not have a venomous sting and new queens are less aggressive than workers. Bee wax appeared in all seasons and the highest rate was from spring to early summer. However, the remains of honeybees were not found in feces; thus, M. flavigula presumably eats honey but not honeybees.

In avian species, addition of aspirin to the diet was shown to improve the egg production and to elevate the proportion of essential fatty acid contents in several body tissues. This study was conducted to investigate the effect of dietary aspirin on the accumulation of essential fatty acids in egg yolk. Laying Japanese quail at 170 days of age were fed practical diets supplemented with graded levels (0, 0.4 and 0.8%) of aspirin for 2 weeks. There were no significant differences in final body weight and liver weight. Food intake and egg weight on the 0.8% aspirin diet were significantly lower than those on the 0 or 0.4% aspirin diet. In the liver and egg yolk lipids, the 16:0 in birds fed the 0.8% aspirin diet was significantly higher than that in birds fed the aspirin-free diet. However, the proportion of n-6 poly-unsaturated fatty acids was not affected by feeding aspirin diets.

This study was performed to investigate the effect on polyunsaturate fatty acid diets and feeding periods on the antithrombosis. the hematological changes in the blood and fatty acid compositions of platelets in rats. Each group of rats was fed a diet containing 20%(W/W) corn oil beef tallow sardine oil and the general stock diet for 10, 20. 40 and 80 days. Rats fed sardine oil diet showed significantly longer bleeding time than any other diet groups after 20 days feeding The whole blood clotting time of sardine oil group fed for 80 days was increased significantly. The number of platelet and the concentration of hemoglobin showed no significant difference among all groups. The number of white blood cell was decreased continously in sardine oil group after 10 days feeding. The level of malondialdehyde generation during thrombin-induced aggregation of platelets was decreased continously in sardine oil grou after 20 days feeding. With regard to the composition of platelet fatty acid the ratio of eicosapentaenoic acid(EPA 20: 5 $\omega$-3) to arachidonic acid(AA 20:4 $\omega$-6) was increased in sardine oil group but decreased in corn oil groups and beef tallow groups with days. In conclusion the rats fed sardine oil diet for more than 20 days showed the fact that EPA induced the antithrombosis. the changes in number of white blood cell and the fatty acid composition of platelets.

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.
