This study examined two groups of students Korean Oriental Medicine majors and Food and Nutrition majors and compared their knowledge of clinical nutrition as well as their tendency to follow healthy lifestyles. In all, 204 college juniors and seniors majoring in Food ＆ Nutrition, and 324 sophomores majoring in General Korean Oriental Medicine were given a questionnaire. Overall, knowledge of clinical nutrition(out of twenty questions) was significantly higher among the students majoring in food and nutrition (p<0.01). Specifically, these students obtained a higher score in the questions pertaining to the following topics: nutritional support(p<0.05), the relationship between menopause and blood cholesterol(p＜0.01), the relationship between weight control and carbohydrates(p＜0.01), the relationship between gout and protein(p＜0.10), the relationship between hyperlipidemia and carbohydrates(p＜0.01), the relationship between trans fatty acids and atherosclerosis(p＜0.01), the relationship between blood potassium levels and kidney disease(p<0.01), and the relationship between weight control and diet and water(p＜0.05). Conversely, students studying General Korean Oriental Medicine had a better knowledge of the relationship between malnutrition and the mortality rate and health complications(p＜0.01). The questions relating to a healthy diet and lifestyle indicated that students majoring in Food and Nutrition had higher incidences of diet irregularity and a higher missing rate (p<0.01); they were more interested in calorie content and nutrients in their diet(p＜0.05); and they were more likely to study about nutritional knowledge during their leisure time (p＜0.01). The results also indicated, however, Korean Oriental Medicine students consumed proportionally more vegetables(p<0.05); and they were more likely to take the stairs than the elevator(p＜0.01).

Attempts were made to determine the effects of 5-Korean wild vegetabel consumptions on blood glucose leveles and orgen-energy metabolisms in streptozotocin-induced diabetic rats. The 5-Korean wild vegetables were : Cassia tora L.(C.t), Lycium chinese Mill(L.c), Trichosanthes kirilowii Max(T.k), Polygonatum odoratum var. Pluriflorum Ohwi(P.o) and Arctium lappa L(A.l). Sixty male Spargue-Dawley rats(160-220g) were induced diabetes mellitus by streptozotocin injection into the tail vein and were devided into 6 groups : a diabetic control and 5-experimental groups. All groups of the rats were fed on a AIN-76 diet, and the 5-experimental groups were fed with each wild vegetable (10%) for four weeks. An increased tendency in body weight of all the groups was observed and the tendency was more significant in L.c, T.k. and P.o. groups. The organ weight of liver and kidney were higher in L.c. and A.l. groups and lower in T.k. group which has shown the improvement from diabetes. Plasma glucose levels were markedly decreased from the 1st week in C.t, T.k. and P.o. groups and the tendency has lasted throughout the four weeks experimental period. The consumption of P.o. has decreased plasma cholesterol level while any significant difference was not seen in plasma protein levels from all the experimental groups. The level of plasma triglyceride was decreased in P.o. group and the levels of plasma free fatty acids were also significantly lower in P.o. and T.k. groups. The liver protein levels were significantly higher in P.o. and T.k. groups and these two groups also showed the negative or relatively small amount of urinary glucose excretion. The experimental group of T.k. has revealed the decreased level of muscles protein and the increased level of muscle glycogen. The 5-Korean wild vegetables contained dietary fiber and 9-analyzed minerals comparable to the ordinary use vegetables.

Background: The biological actions of various ginseng extracts have been studied for treating obesity and diabetes mellitus. However, few studies have evaluated the effects of fermented Korean Red Ginseng (Panax ginseng Meyer) on metabolic syndrome. The present study evaluated the antiobesity and antidiabetic effects of fermented red ginseng (FRG) on old-aged, obese, leptin-deficient (B6.V-Lepob, "ob/ob") mice. Methods: The animals were divided into three groups and given water containing 0%, 0.5%, and 1.0% FRG for 16 wk. The effect of FRG on ob/ob mice was determined by measuring changes in body weight, levels of blood glucose, serum contents of triglycerides, total cholesterol and free fatty acids, messenger RNA (mRNA) expressions of key factors associated with insulin action, such as insulin receptor (IR), lipoprotein lipase (LPL), glucose transporter 1 and 4 (GLUT1 and GLUT4), peroxisome proliferators-activated receptor gamma ($PPAR-{\gamma}$), and phosphoenolpyruvate carboxykinase (PEPCK) in the liver and in muscle, and histology of the liver and pancreas. Results: FRG-treated mice had decreased body weight and blood glucose levels compared with control ob/ob mice. However, anti-obesity effect of FRG was not evident rather than hypoglycemic effect in old aged ob/ob mice. The hyperlipidemia in control group was attenuated in FRG-treated ob/ob mice. The mRNA expressions of IR, LPL, GLUT1, GLUT4, $PPAR-{\gamma}$, and PEPCK in the liver and in muscle were increased in the FRG-treated groups compared with the control group. Conclusion: These results suggest that FRG may play a vital role in improving insulin sensitivity relative to reducing body weight in old-aged ob/ob mice.

Objective: Endometritis is a major disease, that causes infertility in cattle, and is usually categorized as clinical or subclinical endometritis (SCE). The nutritional condition during the dry period is important for recovery after the last stage of the lactation period, and for postpartum production and reproduction. This study aimed to clarify the relationship between nutritional and metabolic characteristics in the dry period, and the risk of postpartum SCE. Methods: Multiparous Holstein dairy cows (n = 25, raised in a tied stall) were used. Endometrial cytological analysis was performed around 30 days post-partum, with 5% to 14% polymorphonuclear (PMN) as a cut-off point to define SCE. Serum levels of glucose, non-esterified fatty acids, β-hydroxybutyric acid (BHBA), blood urea nitrogen, total cholesterol, aspartate aminotransferase, γ-glutamyl transpeptidase, calcium, phosphorus, and magnesium were measured in the cows at the dry period to evaluate energy status, protein metabolism, and mineral metabolism. Results: The incidence of SCE in the cows was 60.0% (n = 15/25) and the mean PMN% in postpartum cows diagnosed as SCE was 8.05%±2.6%. Overall, 17 and 8 samples were collected from the cows in the far-off and close-up periods, respectively. The serum concentration of BHBA in the far-off period and serum glucose concentration in the closeup period were correlated with postpartum PMN% (r = 0.62, p<0.01; r = -0.74, p<0.05, respectively). Serum levels of calcium and magnesium in the dry period were associated with the incidence of postpartum SCE (healthy vs SCE cows, p<0.05). Conclusion: Blood levels of glucose, BHBA, calcium, and magnesium in dry periods could be useful parameters for predicting the risk of postpartum SCE. The present study also suggests that management in the close-up period is essential for promoting recovery from calving fatigue.

규칙적인 운동은 혈압을 낮춰주고 체중조절과 스트레스 해소에도 도움을 주기 때문에 협심증이나 심근경색과 같은 관상동맥질환을 예방하는데 효과가 있다. 동맥경화증을 촉진시키는 위험인자로는 고혈압, 고지혈증, 당뇨병, 비만, 지나친 흡연, 운동부족 등을 들 수 있으며, 동맥경화의 진행은 어려서부터 시작되어 연령의 증가와 어불어심해진다. 특히, 여자보다 남자에게서 더 심하다. 동맥경화증 위험인자가 있는 사람의 경우 식습관과 생활양식, 그리고 운동처방으로 동맥경화성 질환을 예방하는 것이 중요하다. 식이섬유는 체내에서 소화관의 운동을 촉진하여 장관내 체류기간을 단축시키며 콜레스테롤의 흡수를 저해하여 비만, 고지혈증, 동맥경화 및 대장암 등을 예방할 수 있다. 각종 채소류와 해조류는 불포화지방산이 다량으로 함유된 식품으로서 장내에서 콜레스테롤 흡수를 방해하는 역할을 한다. 또한 식물성 기름에 함유되어 있는 필수지방산과 불포화지방은 콜레스테롤의 대사를 촉진하는 반면 흡수를 방해하며, 과일류에는 수용성 식물섬유인 팩틴이 함유되어 있어 체내의 콜레스테롤치를 떨어뜨린다. 콜레스테롤 및 포화지방산이 적고 불포화지방산이 많은 음식을 섭취하도록 하며 식이요법만으로도 콜레스테롤치를 10~15% 감소시킬 수 있다. 운동과 식이를 병행하여 운동을 지속적으로 장기간 할 때 효과가 매우 크다. 운동은 유산소성 운동으로서 운동강도는 HRmax의 60~80$\%$ $Vo_2$ max 50~70$\%$), 운동시간은 15~60분/day, 운동빈도는 3-6회/week가 바람직하다. 특히 심한 고혈압의 경우에는 환자의 상태에 따른 운동처방의 배려가 있어야 되며, 의사와 상의하여 전문적인 처방이 필요하다. 확인되었다.H, ENO1, ADH1 promoter 순으로 나타났지만, 초기 포도당 농도가 높을 때나 에탄을 생산이 심각한 유가식 배양에서는 ENO1 promoter가 inulinase의 구성적 발현ㆍ생산에 더 적합할 것으로 사료된다.라서 체중조절을 위해서는 식이제한 보다는 자유로운 식이 섭취의 방법을 통해 더 많은 운동기간을 가지고 운동을 한다면 체중조절은 물론 근육 대사를 원활히 하여 건강한 생활을 할 수 있으리라 기대한다.공정에서 매우 효과적으로 이용될 수 있을 것으로 판단된다.게 기여하리라고 전망된다.

These experiments were conducted to evaluate the nutritional and feeding value of red pepper seed oil meal (RPSOM) as local vegetable protein ingredients for poultry feeding. In the first experiment, nutritional values of RPSOM were evaluated by analyzing chemical compositions and determining true metabolizable energy (TME), nitrogen corrected TME (TMEn) and true available amino acid (TAAA) contents. According to the chemical analysis, RPSOM contained 22.50％ of crude protein, 4.75％ of ether extract, 27.70％ of crude fiber, 0.34 mg／g of capsaicin and 49.97 ppm of xanthophylls. The values of TME and TMEn determined by force-feeding 16 roosters (ISA-Brown) were 1.73 kcal／g and 1.63 kcal／g on dry matter basis, respectively. The average TAAA value of 16 amino acids measured by the force－feeding technique was 81.70％. These values were used for formulating experimental diets containing various levels of RPSOM for broiler chicks and laying hens. Two feeding trials were made to investigate the effects of dietary incorporation of RPSOM into chicken feed performances of broiler chicks and laying hens. In the broiler feeding (Exp. 2), a total of two hundred twenty-five, 4 wk old male broiler chicks (Ross) were randomly divided into 9 groups of 25 birds each and assigned to three experimental diets containing 0, 5 and 10% RPSOM. The birds were fed ad libitum the diets for 3 wk and feed intake, weight gain and feed conversion rate were determined. At the end of the feeding, the blood levels of glutamate oxaloacetate transaminase (GOT), gamma glutamyl transpeptidase (GGT), blood urea nitrogen (BUN) and cholesterol, and the body and fatty acid compositions of leg muscle were measured. No significant differences were observed in weight gain, feed intake, feed conversion rate, body composition, serum levels of GOT, GGT and BUN among the treatments. However, blood cholesterol level was lower (P＜0.05) in 10% RPSOM diet group than those in the other. The dietary RPSOM at 5 and 10% levels increased the content of linoleic acid (P＜0.05) in leg muscle compared to that of control group. The results indicate that RPSOM can be used for broiler feed up to 10% without any significant negative effects on broiler performance. In the layer feeding (Exp. 3), the effects of dietary RPSOM on the performances of laying hen were investigated by feeding ninety 45 wk old laying hens (ISA-Brown) with experimental diets containing 0, 5 and 10% RPSOM for 4 wk (30 birds per treatment). Measurements were made on egg production rate, egg weight, feed intake, Haugh unit, egg shell strength which was higher (P＜0.05) in layers fed 10% RPSOM diet compared to those fed 0 and 5% RPSOM diets. Thus, it can be concluded that RPSOM can be included into laying hen feed up to 10% without any harmful effects.
