Diets with foliage of Flemingia (Flemingia macrophylla) or Jackfruit (Artocapus heterophyllus were fed to goats with the objective to study nitrogen (N) balance and effect of a daily supplementation of polyethylene glycol (PEG) on intake and digestion. In experiment 1, three male Alpine${\times}$Jamnapary goats with initial weights varying from 26.9 to 27.7 kg were used in a $3{\times}3$ Latin square design in the dry season. Three Alpine${\times}$Bachthao crosses, 15.3-16.7 kg, were used in the same design in the wet season. The three diets were based on chopped whole sugar cane complemented with the two green foliages, Jackfruit and Flemingia, or soybean meal (SBM). The level of dry matter (DM) offered was 4% of body weight (BW), 2.7% as foliage and 1.3% as chopped whole sugar cane. The amount of SBM offered was calculated to give the same amount of crude protein (CP) as the foliages. Each experimental period lasted 32 days (14 days for adaptation, 7 days for collection and 10 days for rest). Feed intake, apparent digestibility of DM, organic matter (OM), CP, neutral detergent fiber (NDF) and acid detergent fiber (ADF) and retained nitrogen (N) were measured by total faecal and urine collection. In experiment 2, four male goats (Alpine${\times}$Jamnapary) with initial weights from 17.1 to 23.1 kg were used in a $4{\times}4$ Latin square design. The four treatments were Jackfruit or Flemingia with or without addition of PEG, which was fed at a level of 5 g/goat and day by mixing with a small amount of rice bran. Each experimental period lasted 15 days (8 days for adaptation, 7 days for collection). Measurements were done as in experiment 1. The DM digestibility was highest (65.9-74.3%) for goats fed the SBM diet in both the dry and wet season. The DM digestibility of goats fed the Jackfruit and the Flemingia diets was similar in both the dry (58.6-59.2% respectively) and the wet season (53.9-56.1% respectively). The CP digestibility was highest (73.0-73.6%) for the SBM diet followed by the Jackfruit diet (47.0-38.5%) and was lowest (36.8-30.0%) for the Flemingia diet in both dry and wet seasons, respectively. The NDF digestibility was low for both the Jackfruit (36.4%) and Flemingia (38.0%) diets in the wet season. All diets resulted in a positive N balance. The N retention was highest (0.465-0.604 g/kg $W^{0.75}$) in the SBM diets and lowest (0.012-0.250 g/kg $W^{0.75}$) in the Flemingia diet. Addition of PEG had no effect on feed intake for any of the diets. PEG added in the Flemingia diet had a positive effect only on NDF digestibility, but the digestibility of the Jackfruit diet was significantly increased. Supplementation with PEG reduced digestibility and N retention of Flemingia, possibly because of the low tannin level, but increased digestibility and N retention for Jackfruit foliage.

The aim of this study was to investigate the effects of mulberry juice and cake powder on blood glucose and lipid status along with intestinal disaccharidase and erythrocyte antioxidative enzyme system in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats weighing $100{\pm}10g$ were randomly assigned to one normal group, and eight STZ-induced diabetic groups: control diet group without mulberry juice and cake powders (DM-C), three mulberry juice powder groups (0.5%: DM-0.5J, 1%: DM-1J, 2%: DM-2J) and low mulberry cake powder groups (0.25%: DM-0.25C, 0.5%: DM-0.5C, 1%: DM-1 C, 2%: DM-2C). After three-week feeding of each experimental diet, diabetes was induced by intravenous injection of 50 mg/kg body weight of STZ in sodium citrate buffer (pH 4.3) via tail vein of eight DM groups. Rats were sacrificed at the 9th day of diabetic states. Level of blood glucose was 505 mg/dl in DM-C group but it was 28% and 39% lower in mulberry juice and cake powder fed groups, respectively, than the DM-C group. Activities of maltase, sucrase and lactase in proximal part of small intestine were significantly lower in the mulberry juice and cake powder groups by $42{\sim}47%$ than those of DM-C group. Erythrocytic superoxide dismutase, glutathione peroxidase and catalase activities were significantly reduced by STZ but increased close to normal levels along with less accumulation of thiobarbituric acid reactive substances (TBARS). Serum levels of triglyceride and total cholesterol and HDL-cholesterol by STZ-DM were reduced and increased respectively, to the norma] levels by the mulberry juice and cake powder. Except the levels of TBARS, the effects on the other measurements by the various dietary levels of mulberry juice and cake powder were almost same and the effect of the cake powder was most significant at the lowest level. These results indicate that mulberry juice and cake powders have consityerable hypoglycemic effect and strengthening antioxidant defense systems at the low levels in diabetic state and may be able to reduce diabetic complications.

The aim of this study was to evaluate the effect of replacing corn grain for sugar cane molasses (MO) or glucose syrup (GS) in the starter concentrate on performance and metabolism of dairy calves. Thirty-six individually housed Holstein male calves were blocked according to weight and date of birth and assigned to one of the starter feed treatments, during an 8 week study: i) starter containing 65% corn with no MO or GS (0MO); ii) starter containing 60% corn and 5% MO (5MO); iii) starter containing 55% corn and 10% MO (10MO); and iv) starter containing 60% corn and 5% GS (5GS). Animals received 4 L of milk replacer daily (20 crude protein, 16 ether extract, 12.5% solids), divided in two meals (0700 and 1700 h). Starter and water were provided ad libitum. Starter intake and fecal score were monitored daily until animals were eight weeks old. Body weight and measurements (withers height, hip width and heart girth) were measured weekly before the morning feeding. From the second week of age, blood samples were collected weekly, 2 h after the morning feeding, for glucose, ${\beta}$-hydroxybutyrate and lactate determination. Ruminal fluid was collected at 4, 6, and 8 weeks of age using an oro-ruminal probe and a suction pump for determination of pH and short-chain fatty acids (SCFA). At the end of the eighth week, animals were harvested to evaluate development of the proximal digestive tract. The composition of the starter did not affect (p>0.05) concentrate intake, weight gain, fecal score, blood parameters, and rumen development. However, treatment 5MO showed higher (p<0.05) total concentration of SCFAs, acetate and propionate than 0MO, and these treatments did not differ from 10MO and 5GS (p>0.05). Thus, it can be concluded that the replacement of corn by 5% or 10% sugar cane molasses or 5% GS on starter concentrate did not impact performance, however it has some positive effects on rumen fermentation which may be beneficial for calves with a developing rumen.

Objectives : The purpose of this study was to investigate the effect of LR3 and SP6 acupuncture on liver damage of streptozotocin-induced diabetic mice. Methods : Male ICR mice were divided into four groups, consisting of the normal mice group(N), acupuncture-free diabetic mice group(Con), LR3-acupuncture diabetic mice group(LR3) and SP6-acupuncture diabetic mice group(SP6). The following measurements were taken: Body weight, food intake and water intake for 2 weeks; liver weight, and glucose levels in the serum and liver; ALT and AST in the serum; reactive oxygen species(ROS), reduced glutathione(GSH) and oxidized glutathione(GSSG) in the liver; and lastly, receptor for advanced glycation endproducts( RAGE), $N{\varepsilon}-carboxymethyl$ lysine(CML), $N{\varepsilon}-carboxyethyl$ lysine(CEL), phosphorylation of inhibitory kappa B alpha($p-I{\kappa}B{\alpha}$), nuclear factor-kappa B($NF-{\kappa}B$), activator protein-1(AP-1), cyclooxygenase-2(COX-2), inducible nitric oxide synthase(iNOS), tumor necrosis factor-alpha($TNF-{\alpha}$), ${\beta}-actin$, cytochrome c and caspase in the liver. Results : The liver weight and GSH/GSSG ratio were significantly increased in SP6 compared to Con. The glucose levels in the liver were significantly decreased in LR3 compared to Con. The generation of ROS and GSSG were significantly decreased in SP6 compared to Con. The expressions of RAGE, CML, AP-1, $TNF-{\alpha}$, cytochrome c and caspase 3 were significantly decreased in LR3 compared to Con. The expressions of $p-I{\kappa}B{\alpha}$, $NF-{\kappa}B$, AP-1, COX-2, iNOS and caspase 3 were significantly decreased in SP6 compared to Con. Conclusion : It is predicted that LR3 acupuncture is related to reduced glucose levels in the liver and expressions of AGE, and that, SP6 acupuncture is related to reduced oxidative stress-related transcription factors and inflammation-related proteins. Therefore, we suggest that LR3 and SP6 acupuncture have protective effects on the liver of streptozotocin-induced diabetic mice by preventing apoptosis.

The purpose of this study was to compare the ear-based rectal temperature measured with a tympanic thermometer with the rectal temperature measured with a glass mercury thermometer in order to test the accuracy of tympanic thermometer and to determine relationship among rectal, axilla, and abdominal temperature in neonates. The samples consisted of thirty four neonates admitted to the neonatal intensive care unit and nursery at an university affiliated hospital. The mean age of the subjects was 4.9 days. The ear-based rectal temperatures were taken with a tympanic thermometer in rectal mode (First Temp Genius 3000). Rectal and axilla temperatures were taken with a glass mercury thermometer, Abdominal temperature was continuously monitored with the probe connected to the servo controller of incubator. The results of the study can be summarized as follows : 1. Intrarater comparison : Agreement between the first and the second ear-based rectal temperature was 97% within 0.1$^{\circ}C$. 2. Comparison of ear-based rectal temperature and the rectal temperature from a glass mercury thermometer : ear-based rectal temperature ranged from 36.95$^{\circ}C$d to 37.95$^{\circ}C$, with a mean of 37.58$^{\circ}C$(SD＝0.22$^{\circ}C$). Rectal temperature from a glass mercury thermometer ranged from 36.2$0^{\circ}C$ to 37.2$0^{\circ}C$, with a mean 36.75$^{\circ}C$(SD＝0.29). The mean difference between both temperatures was 0.84$^{\circ}C$. The correlation coefficient between both temperatures was r＝0.77(p＝0.00). 3. Comparison of rectal and axilla temperature : Axilla temperature ranged from 35.8$0^{\circ}C$ to 37.1$0^{\circ}C$, with a mean of 36.55$^{\circ}C$. The mean absolute difference between the rectal and axilla temperature was 0.23$^{\circ}C$. The correlation coefficient between rectal and axilla was r＝0.67. 4. Comparison of axilla and abdominal temperature : Abdominal temperature ranged from 36.2$0^{\circ}C$ to 37.0$0^{\circ}C$, with a mean of 36.58$^{\circ}C$. The mean absolute difference between axilla and abdominal temperature was only -0.03$^{\circ}C$. Findings of this study suggest that ear-based rectal temperature overestimates the actual rectal temperatures in neonates. Therefore, the interchangeble use of both temperatures in clinics seems problematic. The site offset(adjustment value) programmed in rectal mode of the tympanic thermometer needs to be readjusted. Choosing one optimal site for temperature measurement for each patient, and using the specific site consistently would result in more consistent measurements of changes in body temperature, and thus can be more effective in diagnosing fever or hypothermia.

The purpose of this study was to investigate the effects of the nutrition therapy and drug(simvastatin) treatment on the levels of blood lipids for the hyperlipidemic patients according to genetic polymorphism of apo CIII. Subjects of the study consisted of 43(male: 9, female: 34 )hyperlipidemic patients registered to Kyung Hee Medical Center, Intakes of nutrients for the subjects were determined by 24-hr recall method through a personal interviews. The subjects were instructed to take the hypolipidemic and hypocholesterolemic diets. Compliance was monitored through food records, personal interview, and body-weight measurements. The patients changed their basal diet containing 40. 1g fat(182.7mg cholesterol./day) to a diet containing 30.7g fat(139.2mg cholesterol/day) after 12 weeks of nutrition therapy. The distribution of genotypes for apo CIII by Msp I was 32.5% of TT, 50.0% of TC, and 17.5% of CC. aT the beginning of the study, the level of blood triglyceride was the highest for patients with TT and TC. Following the nutrition therapy, patients with CC exhibited the largest drop of blood triglyceride. Following simvastatin treatment with nutrition therapy, blood LDL-cholesterol decreased in most of the patiens with TT. Meanwhile the distribution of genotypes for apo CII by the Fok I was 10.0% of TT, 47.5% of TC, and 42.5% of CC. The level of blood triglyceride was the highest for patients with CC. Following the nutrition therapy, patients with TC exhibited a significant drop for the blood triglyceride. Following simvastatin treatment with nutrition therapy the level of blood LDL-cholesterol decreased in most of the patients with CC. We concluded that dietary habits and food have been changed by nutrition therapy. And blood lipid levels have been decreased by the restriction of intakes of energy, fat and cholesterol. There was variation in the levels of blood lipids according to apo CII polymorphisms. The level of blood lipids responded to nutrition therapy and drug treatment in different was according to genetic polymorphisms. Accordingly, the choice of individualized therapy based on the patient\\`s genetic polymorphism is very important for effective therapy(Korean J Nutrition 33(8) : 813-823, 2000)

뇌파에 관한 연구는 의학 및 공학 분야에서 많이 활성화 되어 있지만, 침구학에서의 뇌파분석에 과한 연구는 아직 많이 이루어져야 할 부분 중 하나이다. 그러므로 본 연구는 침구요법 중 간접 뜸 자극에 의한 뇌파를 분석하고 자율신경계와의 상관관계를 분석을 하고자 한다. 본 연구의 실험은 간접 쑥 뜸을 인체의 중완, 신궐, 관원의 경혈 점에 자극하고, 자극 전, 자극 중, 자극 후 1시간, 그리고 자극 후 2시간 일 때의 뇌파를 측정한다. 그리고 측정된 데이타는 Matlab 7.0을 이용하여 FFT 및 주파수 파워 스펙트럼을 적용하여 ${\alpha}$, ${\beta}$, ${\delta}$, ${\theta}$파 성분을 자극 단계별로 나누어 주파수 각 성분 비율의 변화, 그리고 진폭의 크기변화량에 대하여 분석 고찰하였다. 본 연구의 결과, EEG 데이터를 FFT를 적용하여 ${\alpha}$, ${\beta}$, ${\delta}$, ${\theta}$파의 비율을 분석한 결과 ${\alpha}$파가 자극 전보다 자극 후 약 2배 정도 증가하는 것을 알 수 있었다. 그리고 전체의 파워스펙트럼 분석에서 ${\alpha}$파, ${\beta}$파의 에너지가 전체적으로 감소하므로 부교감신경이 활성화됨을 알 수 있었다. 본 연구와 기존 연구의 결과를 비교해 보면, 간접 뜸 자극은 자율신경계의 변화에 영향을 줄 수 있으며 ${\alpha}$파의 비율적 증가로 긴장 상태나 스트레스 상태의 사람에게 안정을 가져다 줄 수 있음을 확인 할 수 있었다.

저자들은 일반 흰쥐를 1.5% cholesterol과 0.25% cholic acid, 우지 25% 첨가한 식이로 고지혈증을 유발시킨 후 KH-305를 8주간 경구투여하여 혈중 cholesterol과 HDL-C, LDL-C 등을 측정, 지질대사에 미치는 영향을 알아보았다. 또한, 최대해면체 내압과 내피 관련 NOS 발현정도를 측정하여 음경발기 촉진 및 지속에 미치는 영향을 알아보았다. 그 결과 KH-305를 투여한 모든 그룹에서 고지방식이 그룹보다 총 cholesterol 수치와 LDL-C를 낮추었으며 HDL-C의 수치를 높였다. 최대해면체 내압에서는 KH-305 투여 그룹이 고지방식이 그룹보다 최대해면체 내압에 이르는 시간이 짧았고 최대해면체 내압의 수치가 높았으며 이 중 300mg/kg일 경우 가장 효과가 좋았다. 또한, KH-305 모든 투여 그룹은 고지방식이 그룹과 비교해 볼 때 모든 그룹에서 eNOS와 nNOS의 발현이 뚜렷이 증가되었다. 따라서, 혈중 cholesterol을 낮추면서 NOS의 발현을 증가, 최대해면체 내압이 큰 KH-305는 고지혈증으로 유발된 발기부전에 효능이 있는 약물이 될 수 있으리라 사료된다.
