본 시험은 분채취시간 및 Corn Starch, Glucose Mixture (Starch (50) ＋ Glucose (50))의 급이가 성웅계의 내인성에너지 (FEm＋UEe) 손실에 미치는 영향을 검토하고자 실시한 결과 다음과 같은 성적을 얻었다. 1. Period II(24-28hr)의 분배설량, 에너지량과 N 손실량은 Period I(0-24hr)의 경우보다 높았으나 유의차 (P＝.05)는 없었다. 2. 체중(X)과 분배설량, 에너지 및 N 손실량 (Y) 간에는 유의차 상관관계는 발견되지 않았는데 (P＞.05) 이는 체중이 내인성에너지 (FEm＋UEe) 손실에 영향하지 않는다는 사실을 뒷받침하는 것이었다. 3 Glucose, Mixture 급이구는 절식구에 비하여 분배설량, 에너지 및 N 손실량이 현저하게 감소하였다. (P＜.05). 4. Corn Starch 급이구의 분배지량, N 손실량은 절식구에 비해 유의적 (P＜.05)으로 감소했으나 내인성에너지 손실량은 두 구간 유의차가 없었다. (P＞.05) 이는 Corn Starch의 Apparent Digestibility가 Glucose, Mixture구 보다 낮았음을 지적하는 것이다. 5. 급이구의 N 손실량은 절식구에 비하여 현저히 감소한 사실은 탄수화물 급이가 절식동안 조직의 이화작용에 의한 에너지 손실의 일부를 보완하는 것으로 생각된다.

This study is a basic study on the development of functional substances involved in obesity prevention, lipid metabolism, and immune regulation. Male Sprague-Dawley rats were fed a high-fat diet for 10 weeks. Allium monanthum extracts (AME) were administered orally to obesity-induced rats, and their lipid-lowering, antioxidative and various types of biological effects related to the immune system were examined. Blood free fatty acid and triglyceride concentrations decreased as the dose of AME increased. Total cholesterol and LDL cholesterol concentrations in the blood decreased as the dose of AME increased. The total cholesterol concentrations in the liver of the AME-treated groups were lower than the control group. The thiobarbituric acid reactive concentrations were lower in the plasma and liver of all AME-treated groups than the control group. Plasma AST and ALT activities did not show any significant differences among the treatment groups. IL-$1{\beta}$ and IL-6 concentrations in the liver tended to decrease as the dose of AME increased. TNF-${\alpha}$ and IL-10 concentrations did now show any significant differences compared to the control group. Lower expression levels of TNF-${\alpha}$, Apo-B and Apo-E genes were found in the AME-treated groups. Taken together, these results indicate that AME may show positive effects in lipid lowering, antioxidation and anti-inflammation.

본 연구는 그라비올라 잎 에탄올 추출물(AME)의 항염증 효과에 관하여 알아보기 위하여 LPS에 의해 유도되는 대식세포 염증모델에 AME를 병용 처리하여 다양한 염증매개인자들의 분비능 및 염증억제 기전에 관하여 알아보았다. LPS의 처리에 따라 염증반응이 유도된 RAW 264.7 대식세포에 AME를 병용 처리하였을 때, NO 및 염증성 cytokine(IL-6, $TNF-{\alpha}$ 및 $IL-1{\beta}$)의 분비능이 유의적으로(P<0.05) 감소하는 것을 확인하였다. 또한, AME의 처리에 따라 염증반응의 매개인자인 iNOS 및 COX-2 발현이 유의적으로(P<0.05) 감소하는 것으로 나타났으며, 이러한 항염증 활성의 기전에 관하여 분석한 결과 염증성 단백질 발현의 전사인자인 $NF-{\kappa}B$와 MAPKs 신호전달 경로 억제를 통하여 추출물의 항염증 활성이 나타난다는 사실을 관찰할 수 있었다. 따라서 이러한 결과를 통하여 AME의 처리는 염증반응의 전사인자인 $NF-{\kappa}B$의 발현을 조절함으로써 iNOS 및 COX-2의 발현을 억제하고, 염증성 매개인자인 NO 및 cytokine(IL-6, $TNF-{\alpha}$ 및 $IL-1{\beta}$)의 분비를 억제한다고 판단된다.

본 시험은 기초사료의 에너지수준을 2,400Kcal/kg에서 3,000Kcal/kg까지 달리하고 옥수수와 대두박의 apparent metabolism energy (AME), true metabolism energy (TME)가에 미치는 영창을 검토하고자 실시한바 다음의 결과를 얻었다. 1. 옥수수의 AME 측정치는 2,400Kcal/13%를 계외하곤 각 처리간 유의차가 인정되지 않았으며(P＞0.05) 대두박은 2,800Kcal/13%와 2,800Kcal/15%, 3,000Kcal/16% 간에 유의차가 있었으나, (P＜0.05) 2,600 Kcal/14% 처리와는 유의성이 발견되지 않았다. (P＞0.05) 2. 기초사료의 에너지수준은 2,400kcal/13%를 제외하곤 옥수수 대두박의 AME가에 영향하지 않아 시험사료에 따라 기초사료의 에너지수준을 달리할 필요가 없다. 3. 옥수수 보다 대두박의 표준오차 값이 큰 것은 대치율이 옥수수보다 낮은데서 기인하였다. 4. 옥수수의 TME치는 AME치와 그 경향이 같았으나 대두박의 TME치는 전처리간 없었다. (P＞0.05) 5. 옥수수와 대두박의 AME치와 옥수수의 TME치가 2,400Kcal/13% 처리에서 현저히 감소한 것은 사료내 단미사료간 상호작용에 기인한다고 할 수가 있다.

The apparent metabolisable energy (AME) and N-corrected ME (AMEn) of deoiled rice bran (DORB) were determined with adult quails at 6 and 10- week of age. The DORB obtained from two types of extraction process, Batch (DORB-B) and the Continuous (DORB-C), was each included in a practical type of the reference diet at 20 or 40% level. The analysed crude protein, ether extract, total ash, calcium, phosphorus, glucose and starch content of DORB-B and DORB-C were found at 19.0, 0.79, 17.05, 0.11, 1.92, 2.3, 11.22, and 15.02, 1.56, 13.0, 0.40, 2.76, 2.16, 19.0, respectively. The level of inclusion of DORB in diet appeared to exert a significant effect on the AME and AMEn values. When bioassayed at 20% inclusion level the DORB was found to have a significantly (p<0.01) lower value than that obtained at 40% inclusion level. However, no significant effect of age of quails on the AME values of DORB was evident. The ME bioassays with quails gave significantly (p<0.01) higher AME values for DORB-C than DORB-B thereby indicating that the continuous system of solvent extraction of rice bran is superior to the batch system from this point of view. The AME value of DORB predicted from its chemical composition also revealed that the DORB-C contained approximately 15% more energy than that in DORB-B.

This study was undertaken to determined the metabolizable energy of cereal by the different method. Raw or cooked cereal foods were freeze-dried and fed to Sprague Dawley rat with 200-300g body weight to measure apparent metabolizable energy(AME) values and nitrogen-corrected AME(AMEn) values for four days after three days of preliminary period for adaptation to the diets. The AME values of Karaeddok, raw rice, cooked rice, raw brown rice, raw glutinous rice, cooked glutinous rice, raw barley and cooked barley applerared 4516.1, 3380.6, 4072.2, 3457.0, 4448.0, 2929.4 and 3780.2kcal/kg dry matter, respectively. The AMEn values of karaeddok, raw rice, cooked rice, raw brown rice, cooked brown rice, raw glutinous rice, cooked glutinous rice, raw barley and cooked barley appeared 4421.5, 3349.6, 4160.0, 3918.7, 4039.3, 3572.0, 4552.5, 3009.9 and 3873.4kcal/kg dry matter, respectively. A slight difference was observed when the AME values of the cereals measured in present study were compared with the energy values calculated by various conversion parameters such as Atwater's, Rubner's, Sochun's adn FAO's, indicating that the latter energy values by all conversion factors are acceptabel for several cereals.

Purpose: The aim of this study was to evaluate the effects of active mandibular exercise (AME) in patients with limited mouth opening after maxillomandibular fixation (MMF) release. Methods: The study used a quasi-experimental, nonequivalent control group and a pre test-post test design. Sixty-two patients with Maxillomandibular Fixation Release were assigned to the experimental (n=31) or control group (n=31). The AME was performed in the experimental group for 4 weeks. The exercise AME consisted of maximal mouth opening, lateral excursion and protrusive movement. These movements were repeated ten times a day. After the final exercise of the day, the number of tongue blades used for mouth opening was noted. The effect of AME was evaluated after MMF release at different time intervals: a) immediately, b) after 1 week, c) after 2 weeks, d) after 4 weeks, and e) after 12 weeks. The exercise was assessed using the following criteria: a) mandibular movements, b) pain scores associated with maximal mouth opening, c) discomfort scores associated with range of movement, and d) daily life activities that involve opening the mouth. Results: The experimental group showed significant improvement regarding the range of mandibular movements (maximal mouth opening (F=23.60, p<.001), lateral excursion to the right side (F=5.25, p=.002), lateral excursion to the left side (F=5.97, p=.001), protrusive movement (F=5.51, p=.001)), pain score (F=39.59, p<.001), discomfort score (F=9.38, p<.001). Daily life activities that involve opening the mouth were more favorable compared to those in the control group. Conclusion: The AME in patients after MMF release is helpful for increasing mandibular movement range, decreasing pain and discomfort, and improving day life activities that involve opening the mouth. Therefore, AME is highly recommended as an effective nursing intervention.

Objective: This experiment was to investigate the effect of increasing levels of apparent metabolizable energy ($AME_n$) on the laying performance, egg quality, blood parameters, blood biochemistry, intestinal morphology, and apparent total tract digestibility (ATTD) of energy and nutrients in diets fed to laying hens. Methods: A total of three-hundred twenty 33-week-old Hy-Line Brown laying hens (Gallus domesticus) were evenly assigned to four experimental diets of 2,750, 2,850, 2,950, and 3,050 kcal $AME_n/kg$ in pens with floors covered with deep litter of rice hulls. There were four replicates of each treatment, each consisting of 20 birds in a pen. Results: $AME_n$ intake was increased (linear, p<0.05) with inclusion level of $AME_n$ in diets increased. Feed intake and feed conversion ratio were improved (linear, p<0.01), but hen-day egg production tended to be increased with an increasing level of $AME_n$ in diets. During the experiment, leukocyte concentration and blood biochemistry (total cholesterol, triglyceride, glucose, total protein, calcium, asparate aminotransferase, and alanine transferase were not influenced by increasing level of $AME_n$ in diets. Gross energy and ether extract were increased (linear, p<0.01) as the inclusion level of $AME_n$ in diets increased. Conclusion: Laying hens fed high $AME_n$ diet (i.e., 3,050 kcal/kg in the current experiment) tended to overconsume energy with a positive effect on feed intake, feed conversion ratio, nutrient digestibility, and intestinal morphology but not on egg production and egg mass.

Two experiments were conducted to test the hypothesis that a lipase-based enzyme preparation would increase the AME content of full-fat rice bran (FFRB) by increasing fat digestibility when fed to broiler chickens. Experiment 1 used FFRB from Australia and lasted for 35 days, while Experiment 2 used FFRB from Thailand and lasted for 14 days. Rice bran was substituted in a maize-soybean diet at levels of 90 g/kg (Experiment 1) and at 90 and 180 g/kg in Experiment 2. Total collections of excreta were used for determination of AME content and fat digestibility. In Experiment 1, the enzyme increased the AME content of FFRB between days 4-7, 18-21 and 32-35 by 6.1-16.1% (p>0.05), however this was not associated with improved fat digestibility. In Experiment 2, the enzyme enhanced the AME content of FFRB between days 4-7 (10.42 vs. 9.06, p=0.107) and 11-14 (11.94 vs. 9.93, p=0.041), but again, this was not caused by increased fat digestibility. Inclusion of 180 g/kg depressed the AME content of FFRB by 7.4-11.5% (p>0.10) in conjunction with decreased (p<0.05) fat digestibility between 0-14 days of age. Improvements in bird growth with the enzyme were seen in Experiment 2 but not in Experiment 1. Increases in AME content of FFRB per se were not caused by enhanced fat digestibility, suggesting that the side activities associated with the preparation must have acted singularly or in combination to improve AME content and bird performance. These data show that the response of FFRB to the lipase-based enzyme preparation was dependent upon the geographical origin of the rice bran and the level of FFRB substituted in the basal diet.
