This study was carried out to investigate into the effect of light-emitting diode (LED) for the light quality as a light source on the broccoli seed germination and the physiological activity of vegetable sprouts. We have also germinated seeds of the broccoli and applied LED as a light quality such as blue, green, red, white, yellow and red + blue color lights to their sprouts for 14 hours and kept dark for 10 hours at the temperature of $25^{\circ}C$ (day)/$18^{\circ}C$ (night). Broccoli sprouts were extracted by methanol and their physiological activities were examined. All broccoli seeds were germinated at 3 days after seeding regardless of the light color. Total sprout fresh weight were mostly became highest by 0.389g (10 plants) at 8 days after seeding when their sprouts were grown under blue color light. Total phenol compound contents in broccoli sprouts were extremely increased by $83.0\;mg{\cdot}L^{-1}$ under the white light, and total flavonoid contents were most much more by $72.6\;mg{\cdot}L^{-1}$ under the blue light. DPPH radical scavenging activity at $2,000\;mg{\cdot}L^{-1}$ were most highest by 93.5% in broccoli sprouts grown under the white light. Nitrite radical scavenging activity at the concentration of $500\;mg{\cdot}L^{-1}$ in sprout extracts were the most increased by 66.9% under the yellow light, and tyrosinase inhibition activity at $2,000\;mg{\cdot}L^{-1}$ in sprout extracts were by 14.5% under red light.

In order to study the effects of supplementary $Safmannan^(R)$(Beta-glucan & MOS complex) and $World-Labs^(R)$ (multiple probiotics) on the performance, nutrient availability, small intestinal microflora and immune response in broiler chicks, one thousand hatched broilers ($Ross^(R)$ were assigned to 4 treatments: control(basal diet), $BMD^(R),\;Safmannan^(R)\;and\;World-Labs^(R)$. There were no significant differences in the performance and in serum IgG, ND titre. However parameters of leukocytes and erythrocytes were significantly different among treatments (p<0.05). Leukocytes and RBC of $World-Labs^(R)\;and\;Safmannan^(R)$ were mostly lower than $BMD^(R)$ and control whereby MCH and MCHC of $World-Labs^(R)\;and\;Safmannan^(R)$ were higher than other treatments. The cfu of intestinal microflora had no significant differences among treatments. The $BMD^(R)$ treatment was higher than others in amino acid and crude fat availability and $World-Labs^(R)$ was higher than others in crude fiber availability. It was concluded that supplements used in the present experiment did not significantly affect the production parameters. However, significant impact on blood parameters, especially on leucocytes, may need further investigation.

This study was conducted to compare the effect of feeding molting and fasting molting on the performance, egg quality, and visceral organs in laying hens for animal welfare. Eighty one 62-wk-old White Leghorn hens that egg production was over 80% and average weight was $1.6{\pm}0.3\;kg$ were used in this study. Treatments were control (non-molt treatment), feeding molt treatment, and fasting molt treatment. The three treatments were administered to three replicate group of nine hens wherein each group. All treatment groups were fed the basal diet (CP 15%, ME 2,700 kal/kg) for two weeks as the adaptation period. Induced molt diets contains low CP (6.7%) and low energy (2,200 kal/kg). Test periods were 14 days for feeding molting and 10 days for fasting molting. Egg production decreased to be 0% at 10 days of feeding molting treatment, but at 2 or 3 days of fasting molting treatment. Egg production restarted after 19 days ending molt at feeding molting treatment, while after 24 days at fasting molting treatment. On the egg quality was improved at molting treatments (p<0.05) except egg yolk. Egg shell tissue was crowded at molting treatment to compare to control. Liver weights, heart weight, and oviduct weight of laying hens decreased at molting treatments (p<0.05). Finally, feeding molting might could be replaced fasting molting on the welfare and further studies were needed about molting program.

This paper constitutes a descriptive investigation and used a structured questionnaire to investigate nurses' and doctors' recognition of cancer patients. The subjects were extracted from the medical personnel working at the internal medicine, the surgery ward, the obstetrics and gynecology department, the pediatrics department, the cancer ward, and the emergency room of five general hospitals located in Seoul and Gyeonggi Province. The research lasted from August, 2001 to September 2001. Total 137 nurses and 65 doctors were included and made out the questionnaires directly distributed by the investigator. The study tool was also developed by the investigator and consisted of such items as the demographic and social characteristics, the medical personnel's recognition degree of cancer and cancer patients, their recognition of the management of cancer patients, and their participation in a hospice. The results were analyzed using the SPSS Window program in terms of technological statistics, ranks, t-test, and ANOVA. The reliability was represented in Cronbach' α=.75. The nurses' and doctors' recognition degree of cancer and cancer patients had an overall average of 3.86 at the 5 point-scale. The items that received an average of 4.0 or more included 'Medical personnel should explain about the cancer cure plans to the cancer patient and his or her family', 'A patient whose case has been diagnosed as a terminal cancer should be notified of it, 'If I were a cancer patient, I would want to get informed of it,' and 'Cancer shall be conquered whenever it is'. In the meantime, the items that received an average of 3.0 or less was 'My relationship with the cancer patient's family has gotten worse since I announced his or her impending death.' And according to the general characteristics and the difference test, the recognition degree of cancer and cancer patient was high among the subgroups of nurses, females, married persons, who were in their 30s, who had a family member that was a cancer patient, and who received a hospice education. The biggest number of the nurses and doctors saw 'a gradual approach over several days'(68.8%) as a method to tell a cancer patient about his or her cancer diagnosis or impending death. Those who usually tell tragic news were the physician in charge(62.8%), the family members or relatives(32.1%) and the clergymen(3.8%) in the order. The greatest number of them recommended a cancer patient's home as the place where he or she should face death because they thought 'it would stabilize his or her mentality'(91.9%) while a number of them recommended the hospital because they 'should give the psychological satisfaction to the patient'(40%) or 'should try their best until the last moment of the patient's death'(30%). A majority of the medical personnel regarded 'smoking or drinking' and 'diet' as the causes of cancer. The biggest symptom of a cancer patient was 'pain' and the pain management of a cancer patient was mostly impeded by the 'excessive fear of drug addiction, tolerance to drugs and side effects of drugs' by medical personnel, the patient, and his or her family. The most frequently adopted treatment plan of a terminal cancer patient was 'to do whatever the patient or his or her family wants' to resort to a hospice' and 'to continue active treatment efforts' in the order. The biggest reasons why a terminal cancer patient went to see a doctor were 'pain alleviation' 'control of symptoms other than pain(intravenous supply)' and 'incapability of the patient's family' in the order. Terminal cancer patients placed their major concern in 'spiritual(religious) matter' 'emotional matters' their family' 'existence' and 'physical matters' in the order. 113(58.5%) of the whole medical personnel answered they 'would recommend' an alternative treatment to a terminal cancer patient mostly because they assumed it would 'stabilize the patient's mentality.' Meanwhile, 80(41.5%) of them chose 'not to recommend it mostly due to the unverified effects and high cost of it(78.7%). A majority of them, I. e. 190(94.1%) subjects said they 'would recommend' a hospice to a terminal cancer patient mostly because they thought it would help the patient to 'mentally prepare'(66.6%) Only 17.3% of them, however, had received a hospice education, most of which was done through the hospital duty education(41.4%) and volunteer training(34.5%). The follows are results of this study: 1. The nurses and the doctors turned out to be still passive and experience confusion in dealing with a cancer patient despite their great sense of responsibility for him or her. 2.Nurses and Doctors realize the need of a hospice, but an extremely small number of them participate in a hospice education or performance. Thus, a whole recognition of a hospice should be changed, for which purpose a hospice education for nurses and doctors should be provided. 3.Terminal cancer patients preferred their home to a hospital as the place to face their impending death because they felt it would bring 'mental stability.' And most of nurses and doctors think it would be unnecessary for them to be hospitalized just for control of their symptoms. Accordingly a terminal cancer patient can be cared at home, and a home hospice care needs to be activated.

This study was attempted to evaluate the effectiveness of extract of fermented red pepper The extract of fermented red pepper was prepared from fermented red pepper puree and polydextrose. Sixteen female college students were participated in this 8 weeks weight control program. All subjects were randomly assigned to the Internet Diet (ID) group or Internet I, fermented red pepper (IR) group. Mean energy intake of ID group was 1,279.9$\pm$112.0 kcal (carbohydrate: 66.9%, protein: 17.4%, fat: 15.6%) and IR group consumed 1,223.8$\pm$57.1 kcal (carbohydrate: 66.3%, protein: 19.3%, fat: 14.4%) during program. The ID group lost 2.5$\pm$1.0 kg of body weight, 0,9$\pm$0,7 kg of fat mass and 1.6$\pm$0.7 kg of lean body mass, and the IR group lost 2.7$\pm$0.3 kg of body weight, 1.8$\pm$0.6 kg of fat mass and 0.9$\pm$0.7 kg of lean body mass. There was no significant differences in the loss of total body weight & lean body mass between two groups, however, the fat mass and the abdominal fat were significantly decreased in the IR group compared to the IC group (p<0.05) The ID group experienced a significantly reduced Resting Metabolic Rate (RMR), however, IC group slightly increased. The change of RMR between groups were significantly different (p<0.05) . There were no differences in the change of blood glucose, total-cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride between groups. Therefore, the intake of fermented red pepper doting the weight control program might decreased the body fat especially abdominal fat and prevent the decline of RMR during weight reduction period.

The effects of combined garlic and medicinal plant extracts such as Gyeolmyeongja (Cassia obtusifolia Linne), Hasuo (Polygoni multiflori Radix), Youngji (Ganoderma lucium) and Sansayuk (Crataegus pinnatifida Bunge) on the antioxidant activity and lipid levels in the livers of rats fed a high cholesterol diet were analyzed. Total phenol and flavonoid contents were the highest in the Gyeolmyeongja by $151.02{\pm}5.20\;mg$/100 g and $43.69{\pm}5.58\;mg$/100 g. Electron donating ability, reducing power and hydroxyl radical scavenging activity were significantly increased when over 0.3% garlic extract was added. The antioxidant activity of linoleic acid in $\beta$- carotene increased in a dose dependant manner in response to the concentration of garlic extract. In livers of rats, the content of total lipids was significantly decreased by feeding garlic and medicinal plants composites; in particular, the group in which 0.7% garlic extract was added was the lowest. Total cholesterol was 14.95 mg/g in the control group; its level was lower in the groups fed garlic and medicinal plants composites, ranging from 11.47 to 11.86 mg/g. Triglyceride concentration was significantly decreased in the group fed 0.7% garlic extracts, with 46.42 mg/g compared to groups fed 0.3% and 0.5%. TBARS content showed a 15.8~17.6% decrease in groups fed 0.5~0.7% garlic extract and medicinal plants composites. Antioxidant activity was significantly increased in groups fed over 0.5% garlic extract compared to the control group. This study shows that garlic and medicinal plant composites intake is able to reduce the levels of liver lipids in hypercholesterolemic rats.

Ixeris sonchifolia Hance (Godulbaegi), Oenanthe javanica (Dolminari), Fagopyrum esculentum Moench (Buckwheat>, Hizikia fusiforme (Seaweed Fusiforme) and Zingiber ojficinale Roscoe (Ginger) have been used respectively as one of folk remedies as well as food materials. However, reportedly few studies on their immunomodulating effects have been made, although it has been known from other preceding studies that the ex vivo supplementation of each Ish, OJ, Fem, Hf, Zor water extracts tends to enhance the proliferation of splenocyte in comparison to the control group. This study on the combined immunomodulative effect of water extract mixture of these five food materials (Ish + Oj + Fem +Hf+Zor) lasted covering seven or eight weeks. The old mice (balb/c) was fed ad libitum on chow diet, and the water extract of plant mixture was orally administrated every other day for four weeks at two different concentrations (50 and 500 mg/kg B.W) . After preparing the single cell suspension, the proliferation of splenocyte was determined by MTT (3-[4,5-dimethylthiazol-2-y]-2,5-diphenyl terazolium bromide) assay. The production of cytokine ($IL-{\beta}$, IL-6, and $TNF-{\alpha}$) which was secreted by macrophages stimulated with LPS or not was detected by ELISA assay using the cytokine kit. After the 48 hours of incubation with the mitogen (ConA or LPS) stimulation, the proliferation of the mice splenocyt in the experimental group statisticaly increased at both of two different concentrations in comparison to the control group. The cytokines production was more significantly enhanced at the lower supplementation (50 mg/kg B.W.) group than at the higher concentration (500 mg/kg B.W.). The result of this study may suggest that the supplementation of water extract of plant mixture can regulate and enhance the immune function by increasing the splenocyte proliferation and regulating the cytokine production capacity by the activated macrophages in mice.

The effects of bisphenol A (BPA), known as one of the endocrine disrupting chemicals (EDCs), on the hatching of fertilized eggs (FE) and the spawning of adult fish in songsari, Oryzias latipes were investigated. In condition of the experimental groups, incubated water temperature was $25.0{\pm}0.5^{\circ}C$ and photoperiod was 16 h (light) : 8 h (dark). fE were exposed to aqueous solutions of BPA at nominal concentration of 50, 100 and $200 {\mu}g/l$. The time required in hatching of FE was long in the BPA $50 and 100 {\mu}g/l$ treatment groups when compared to the controls, and in the BPA $200 {\mu}g/l$ treatment group, FE failed to hatch. And also hatching rate was decreased in the BPA treatment groups in comparison to the controls, Adult fishes were reared to oral administration via a diet of 50, 100 and $200 {\mu}g/g$ body weight BPA concentration for 3 weeks, Number of total eggs spawned in the adult fish were fewer in the BPA 100 and 200 treatment groups than in the controls and BPA 50 treatment group. Frequency of abnormal eggs in the total eggs spawned was 11.8 and $16.2{\%}$ in the control and acetone carrier control lower than 36.8, 46,8 and $74.1{\%}$ in the BPA 50, 100 and 200 treatment groups, respectively. And hatching rate of FE decreased in the BPA treatment groups in comparison to the controls. In these results, inhibition of the hatching of FE and the quantity and quality of spawned eggs in adult fish were observed from BPA treatment groups when compared to the controls.

This study investigated the effect of improved liver function in rats administered with ethanol by kimchi lactic acid bacteria with high GABA producing capacity. Sprague-Dawley male rats were divided into four groups; normal diet control (NC), ethanol control (EC), ethanol＋Lactobacillus sp. OPK2-59 normal powder (EL1), ethanol＋Lactobacillus sp. OPK2-59 GABA powder (EL2) and fed for 6 weeks. Analysis showed that there were no significant differences in body weight and feed consumption among the groups during the experimental period. Also, there were no significant differences in organ weight among the groups. The test results showed total cholesterol and triglyceride in the blood concentration that were increased by ethanol administration were significantly lowered in EL2 group. Liver triglyceride was also significantly lowered in the EL2 group compared with the EC group. Serum GOT and GPT, and liver GOT levels were significantly lower in the EL2 group compared with the EC group. Serum ethanol concentration was lower in the EL1 and EL2 groups compared with the EC group. SOD activities in liver were significantly increased in the EL1 and EL2 groups compared with the EC group. These results suggest that Lactobacillus sp. OPK2-59 GABA powder improves lipid and enzyme profiles of rats administered with ethanol.
