Cho, Tak(曺倬)'s Yi-Yang-Pyun(二養編), first published in the 12 year of Kwang-Hae-Kun(光海君) era(1620), is composed of two parts. The first part is an edition of various Confucian scriptures that is used to control and restrain the mind. The second pan, considering mostly of contents borrowed from medical works, anthologies and books on yang-saeng(養生), is used to maintain the well-being of the body. Yi-Yang-Pyun shows several distinct characteristics of Yang-saeng ideas. first, it follows the teachings of Yi, Hwang(李滉) which denotes the state of body and mind according to the Kyung(敬) philosophy. 'Kyung' is a state of being that does not require bondage as it automatically reveres the mind. Therefore, actively fostering the body and mind is to maintain this respective state of being. Second, it has summarized and arranged certain medical contents from the Dong-Eui-Bo-Kam(東醫寶鑑) for the purpose of discovering the truth underlying one's body in an effort to pursue the logics of universal nature. Third, although it was based on the contents of Confucianism related books, it widely encompassed the regimen of Taoism. Fundamentally, the Confucian had regarded the Taoism as a heretic, but accepted it in e influence of Zhu xi(朱熹) who interpretated Can-Tong-Qi(參同契) with Confucian perspectives and put in practice the regimen of Taoism. In this context, Yi-Yang-Pyun also used jointly Taoism-related books with Confucian scriptures. Although Taoist regimen was accepted, elixir(外丹), conjury of Taoist hermit(神仙方術) and issues which run counter to morality like sexual practices(房中術) were not. Most of regimens used were related to disease-prevention and health-enhancement like breathing(服氣法), gym-nastics(導引), Diet(服餌) etc. Ideas of Yi-Yang-Pyun, written from Confucian perspectives, latter heavily influenced on scholars of inner elixir(內丹).

A trial was conducted to determine the effect of low crude protein (CP) diets with constant metabolizable energy to crude protein (ME:CP) ratio on growth, body composition and nutrient utilization of broiler chicks from 1 to 26 days of age. Four dietary treatments having four levels of CP and ME as 23, 22, 21 and 20% and 3,036, 2,904, 2,772 and 2,640 kcal/kg, respectively, were formulated and a ME:CP ratio of 132 was maintained in all the diets. Digestible lysine was maintained at 1.10 of the diet. A total of 1,760 day-old Hubbard broiler chicks were randomly divided into 16 experimental units and each diet was offered to four experimental units at random. Feed intake was increased (p<0.05) while weight gain and feed conversion ratio were adversely affected (p<0.05) when the diets with low CP and ME were fed to broilers. Total protein intake and total ME intake were linearly decreased (p<0.05) and protein efficiency ratio and energy efficiency ratio were lower (p<0.05) than in the chicks fed dietary regimen with 22% CP and 2,904 kcal/kg ME. The whole body analysis of the birds revealed that chicks fed the lowest dietary regimens retained less (p<0.05) nitrogen and more ether extract than chicks fed the control diet, however, body dry matter, total body ash and fat free body protein were not affected. Similarly, protein and energy utilization were also unaffected by the dietary treatments. In summary, chicks fed low CP diets with constant ME:CP ratio grew slower, used feed less efficiently and retained less protein and more body fat than chicks fed the control diet.

Carcinogenicity of di(2-ethylhexyl)phthalate(DEHP) to the mose forestomach and its inhibitor activity for the initiation of Benzo[a]pyrene(BP)-induced mouse forestomach neoplasia were studied on the mouse forestomach carcinogenesis regimen. One hundred female ICR mice(6~7 weeks of age) were hosed in a poly-carbonate cage (4 mice/cage) in a humidity- and temperature-controlled room subjected to a semipurified diet for a week. Mice were divided into 4 treatment groups (25 mice/treatment): Basal diet, DEHP, BP, and BP+DEHP. On Monday and wednesday, 0.1ML DEHP mixed with 0.1ml olive oil (for DEHP and DEHP+BP treatment groups) or 0.1ml saline+0.1ml olive oil (for basal diet group) was intubated, p.o., and on Friday, 2mg BP dissolved in 0.2ml olive oil (for BP and BP+DEHP treatment groups) was intubated, p.o. This cycle was repeated for 4 weeks. Beginning with the first intubation of BP an continuing thereafter, body weight and food intake were recorded once and twice weekly, respectively. All surviving mice were sacrificed 22 weeks after the first dose of BP intubation and countered forestomach tumor. No tumor was formed by DEHP treatment. 5.75 tumors per mouse was formed by BP treatment, whereas its number was reduced to 4.53 by BP+DEHP treatment. Similar results were seen in the tumor incidence. Body weight gain was not affected by DEHP treatment, when compared to that b basal diet treatment. The body weight was significantly reduced by BP treatment, but its reduction was recovered to the level of the basal diet group by BP+DEHP treatment. No significant difference was seen in food intake among all treatment groups. These results indicate that DEHP lacks carcinogenic activity to the mose forestomach and rather inhibits the initiation of BP-induced mose forestomach neoplasia.

The present study was designed to assess whether dietary inorganic and organic selenium (Se) could affect antioxidant enzymes, including superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST), and the level of malondialdehyde (MDA), a marker of lipid peroxidation, in the intestine, serum, liver, and gastrocnemius muscle of Korean native goats. A total of eighteen Korean native goats was allotted into three dietary groups, consisting of basal diet (CON), or basal diet with either 0.25 ppm inorganic (IOSEL) or 0.25 ppm organic Se (ORSEL), and fed the corresponding diets for 5 wks. Growth performance, including body weight and total gain, and blood biochemical profiles, including GSH-Px, were not significantly different between the three dietary groups. Also, the specific activities of SOD, GSH-Px, and GST, and the level of MDA in the intestinal mucosa and liver from goats were not substantially affected by either inorganic Se or organic Se. However, goats fed the diet containing organic Se showed a significant increase in GSH-Px and GST activities in the gastrocnemius muscle compared with those fed the basal diet. In conclusion, increased muscle GSH-Px and GST activities suggest that dietary organic Se may affect, at least in part, the antioxidant defense system in muscle of Korean native goats under the conditions of our feeding regimen.

This study intended to investigate the growth performance and meat quality traits in broilers fed different regimens of NaCl over a period of 35 days. Seven hundred and fifty 1-day-old chicks (Cobb 500) were randomly assigned to five NaCl feeding regimens to obtain three replicates for each regimen. Broilers in CON group were provided with concentrations of 0.35% NaCl for the duration of the experimental period. The other groups were provided with two concentrations of NaCl (0.45% and 0.55%) under two durations, namely: 1) 1~28 d: 0.45% or 0.55% NaCl for 28 days then CON; and 2) 1~35 d: 0.45% or 0.55% NaCl for 35 days. Broilers fed 0.55% NaCl for 1~35 d showed improved (P<0.05) growth performance compared with broilers fed the CON regimen. Moreover, higher water holding capacity of breast meat was shown by the broilers fed 0.55% NaCl for 1~28 d when compared with that in broilers fed the CON diet (P<0.05). Broilers fed 0.45% NaCl showed an increase (P<0.05) in the lightness of the meat over CON diet and the 0.55% NaCl diet. In addition, broilers offered CON had the highest redness value and highest crude ash content in the breast meat (P<0.05). Feeding 0.45% NaCl for 1~35 d and 0.55% NaCl for 1~28 d resulted in a higher (P<0.05) protein content in breast meat. In conclusion, broilers fed diets with 0.55% NaCl for 1~35 d showed improved growth performance as well as water holding capacity and protein content of the breast meat.

The aim of the present study was to determine the effect of dietary cultured wild ginseng root (CWGR) supplementation on goat milk composition and ginsenoside profiles. Sixteen Saanen dairy goats were allocated to two balanced groups based on lactation period, body weight ($38.6{\pm}3.2kg$), and dairy milk yield ($2.85{\pm}1.2kg$), and were kept in separate pens. Goats were fed a total mixed ration (TMR) feed (2.3 kg/d, dry matter basis) and 1.5 g of CWGR powder was supplemented in the experimental diet. The total feeding period was 3 weeks, and milk and blood samples were collected on the last three days of the experimental period. There was no effect of CWGR on daily milk yield and milk composition (fat, protein, lactose, and solid-not-fat). However, the CWGR-treatment group had significantly higher plasma IgG and protein contents than the control group (P < 0.05). Significant amounts of ginsenosides were observed in the milk of the CWGR-treatment group, whereas ginsenosides were not detected in the milk of the control group. In conclusion, dietary CWGR was a useful regimen to produce functional goat milk enriched in ginsenosides.

This study was conducted to determine the effects of dietary swine manure and food waste on feeding and drinking behaviours in broiler chicks. A total of 240 birds with 40g of initial weight were randomly assigned in the 8$\times$3 randomized complete block design and 10 birds per replicate. Extrusion recycled feeds(ERF) were prepared by extruding a mixture of 40% swine manure+40% food waste(FW)+20% corn. The birds assigned to one of the 8 dietary regimens; 0, 10, 30, 40% ERF of 20, 40, 60% FW in the place of a commercial boiler starter diet. Video recording were made after one week of adaptation period to the regimen. The tapes were played in a slow motion to examine feeding and drinking behaviour. Feeding and drinking times were greater in the day time at the night. Feeding times peaked at 4 hour intervals. Drinking time increased about 2 times on FW feeding compared to the other treatment groups. The results indicated that feeding and drinking behaviour could be influenced by the dietary regimens and that FW feeding increased drinking. The data also suggested that the FW could replace within 40% of broiler starter diet.

The author previously reported that the addition of inuloprebiotics to broiler diets produces growth performance that is superior to antibiotic supplementation. The present study furthered this work by evaluating the quality with thiobarbituric acid reactive substances (TBARS) of the meat from chickens fed inuloprebiotics produced using Korean Jerusalem artichoke. Male Ross 308 broilers (n=240) were randomly allotted to a 35 day regimen of dietary control (no supplementation), dietary antibiotics supplementation (8 mg avilamycin/kg diet), or dietary inuloprebiotic supplementation (450 mg inuloprebiotics/kg diet). The pH, water holding capacity, L*value (lightness), and b*value (yellowness) of the chicken meat weres ignificantly higher in the inuloprebiotic group. The TBARS value of chicken meat stored at low temperature tended to increase according to the length of storage, and was significantly lower in the inuloprebiotics group. The sensory scores of the cooked chicken meat were significantly higher in the inuloprebiotics group. The results indicate that the addition of inuloprebiotics as anantimicrobial agent to broiler diets can greatly improve the quality and self-life with reducing TBARS of chicken meat.

The purpose of this study was designed to observe the effects of Zizyphus jujuba seed extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 4 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride (TG), phospholipid (PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (group 2 (cholesterol+water), group 3 (cholesterol+Zizyphus jujuba seed extract)) than those in the control group (group 1, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum ware remarkably lower in the group 3 than those in the group 2. In the ratio of HIDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Zizyphus jujuba seed extract administration group was higher percentage than in the group 2. The activities of aspartate aminotransferase (AST), alanine amino-transferase (ALT), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Zizyphus jujuba seed extract administration group (group 3) than in the cholesterol diet group (group 2). From the above research, Zizyphus jujuba seeds were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Zizyphus jujuba seeds were more effective as a therapeutic regimen for the control of metabolic derangements in adult disease.

This study was carried out to determine the effects of Jerusalem artichoke (JA) powder , JA extract and chicory extract on lipid metabolism in SD rats. The experimental groups were divided into 4 groups ; control, JA powder JA extract and chicory extract. The animals were fed ad libitum each of the experimental diets for 3 weeks. After 3 weeks, the wet weights of cecum were significantly increased in rats fed JA powder and chicory extract. Cecal contents were slightly increased in all experimental groups. Serum HDL-cholesterol, HDL-cholesterol/total cholesterol ratio and atherogenic index were significantly increased in the chicory extract group. Serum triglyceride, total cholesterol and LDL-cholesterol levels were not different among the diet groups. Although the feeding of chicory extract significantly lowered total lipid of liver, there was no difference in levels of triglyceride and total cholesterol. The content of fecal lipiid and cholesterol were significantly higher in the Ja extract and chicory extract group than other groups. Fecal bile acid was significantly increased in the chicory extract group. These results indicate that chicory extract is an effective regimen for improvement of lipid metabolism in SD rats.
