This experiment was conducted to investigate the effects of dietary energy levels of gestating gilts on physiological parameters and reproductive performance for primiparous sows. A total of 40 F1 gilts (Large White${\times}$Landrace) were allocated to 4 treatments using a completely randomized design (CRD). Four different experimental diets contained 3,165, 3,265 3,365 and 3,465 kcal of ME/kg and each diet was provided to gilts at 2.0 kg/d during gestation. Consequently, energy intake of each treatment of gestating gilts was 6,330, 6,530, 6,730 and 6,930 kcal ME/kg, respectively. During the whole gestation period, body weight, fat mass gain and backfat thickness of gilts were increased in proportion to dietary energy levels (p<0.01). However, estimated protein mass gain of gilts was not affected by dietary energy level (p>0.10). At farrowing, the total number of pigs born per litter did not show any significant difference among treatments. However, the number of pigs born alive per litter in treatment 6,730 kcal ME/d was significantly higher than that of other treatments (p<0.05). Moreover, litter weight at birth was improved as dietary energy level was increased (p<0.05). Feed intake of sows during lactation tended to decrease as dietary energy level of gestation was increased, but litter weight gain was not affected by dietary treatment during the gestation period. Fat content in colostrum was higher as dietary energy level was increased during gestation. The concentration of blood estradiol-$17{\beta}$ was increased and was higher at the first trimester of gestation in 6,730 kcal ME/d treatment compared to other treatments. These results suggested that increased dietary energy level during gestation resulted in higher body weight and backfat thickness of sows. In addition, reproductive performance of the sow, such as litter weight at farrowing and the number of pigs born alive, was improved when 6,730 kcal of ME/d treatment diet was provided. Consequently, the NRC (1998) recommendation of energy for gestating gilts (6,015 to 6,150 kcal of ME/d) should be reevaluated to maximize reproductive performance because recent high-producing sows require much more energy to produce a large litter size and heavier piglets from the first parity.

Background: In South Korea, as an aged society, an understanding of dementia and its risk factors is important from clinical and healthcare policy perspectives. Relationship between cognitive impairment and body weight or weight changes have been reported, but these were contradictory. We have evaluated the association between weight changes and cognitive decline using national level longitudinal data. Methods: Data from the Korean Longitudinal Study of Ageing from 2006 to 2012 were used. Association between weight changes and decline in cognitive function as measured by K-MMSE (the Korean version of the Mini-mental state examination) score was assessed by multivariate logistic regression. Weight changes were calculated from 1st wave and 3rd wave survey data, and classified into five groups as stable, increases, decreases of >10%, or 5%-10%. Results: About 37% of the total participants (n=4,512) were 65 years or older. These participants made up the largest proportion of the groups with weight change exceeding 10%. Multivariate logistic regression analyses revealed that weight changes exceeding 10% (10% increase vs stable, adjusted OR [aOR] 1.47, 95% confidence interval (CI) 1.11-1.95; 10% decrease vs stable, aOR 1.44, 95% CI 1.11-1.88) were significant predictive factors for decline in cognitive function. In subgroup analyses, the association between weight changes and cognitive decline was significant in males aged over 65 years and in normal BMI groups. Conclusion: Weight changes, both increases and decreases exceeding 10% of baseline, were significantly associated with declines in cognitive function among older adults in South Korea.

백김치의 생체내 Am독성억제효과를 확인하기 위하여 Am 식이에 10% 백김치(동결 건조분말) 첨가사료로 사육한 흰쥐 의 성장회복능을 실험한 결과를 요약하면 다음과 같다. Am 식이군의 섭취량이 양적으로 다른 군에 비해 적었으며, 기본 식이군 생배추식이군, 백김치식이군은 거의 같은 섭취량을 보였다. 기본식이군의 체중이 사육종료일에 289.4 g에 달하는데 비해 Am식이군은 229.8 g으로 기본식이군의 79.4%에 불과해 체중증가 현상이 크게 저조하였다. 그러나 백김치를 첨가한 식이군의 경우는 설사증상이 없어지고 체중도 기본 식이군의 경우와 비슷한 수준까지 회복상태를 보여 백김치의 Am에 대한 독성억제효과를 나타내었다. 변의 총배설량은 백김치식이군(1737.99 g/3 weeks)이 기본식이군의 약 15배, 생배추식이군의 약 1.6배로 백김치가 변부피를 증가시키는 데 가장 효과적인 것으로 확인되었다. 대장과 맹장의 무게는 생배추 및 백김치식이군에서 유의적 (P<0.05)인 증가를 나타내었다. 또한 신장의 무게는 Am식이군에서 유의적인 감소를 나타내어 Am의 독성이 신장과 깊은 상관성이 있음을 시사하고 있었다. Am식이군의 단백질(50.26%) 및 지질소화율 (58.37%)이 백김치식이군의 단백질(77.30%)및 지질소화율 (92.12%)에 비하여 매우 낮았는데, 이것은 이들 영양소의 낮은 소화율이 횐쥐의 체중저하에 직접적인 영향을 미친 것으로 생각되었다. 백김치의 수용성 및 불용성식이섬유는 소화관을 통과한 형태 변화가 뚜렷하게 관찰되었다. 변의 배설 형태는 백김치식이군의 변이 가장 부피가 크고 일정한 크기를 보였다.

주부 7명을 대상으로 주3회 1시간씩 12주간동안 실시한 유산소운동과 웨이트트레이닝이 체구성 및 혈중지질에 미치는 영향을 알아보기 위해 운동을 실시한 후 체중, 제지방체중, 체지방률, 비만도, 혈중지질농도를 측정하여 운동전후를 비교 분석한 결과 다음과 같은 결론을 얻었다. 1. 운동 후 체중과 체지방률은 약간 감소하였으나 유의한 차는 없었고 운동 후 제지방체중은 1.3%로 유의한 증가 (p<.05)를 나타냈다. BMI와 RBW도 약간 감소를 보였으나 유의한 차는 없었다. 2. 에너지섭취량은 운동전 1929.9cal이고 운동후 1896. 0cal로 비슷한 섭취량을 보였다. 3. 혈중지질농도에 있어서 운동전에 비해 운동후에 TC, LDL-C는 약간 증가했고 HDL-C는 22.7% 증가로 유의한 차를 나타내었으며, HDL-C/TC는 운동전에 비해 13.2% 증가로 유의한 차 (p<.05)를 나타냈다. 그리고 TG는 24.5 % 감소로 유의한 차(p<.05)를 나타냈다. 이상의 결과로 볼 때, 12주 동안 평상시와 같은 식사를 하고 운동후의 체구성 비율을 비교해 본 결과 체중, 체지방량, 비만도가 감소하는 경향이 나타났고 제지방체중은 증가되었음을 알수 있었다. 즉 이러한 결과는 다이어트를 하지않고도 운동을 통해 체중감소를 가져올 수 있다는 증거이며, 체중의 감소 결과는 근육이 발달된 반면, 체지방률의 감소를 보였다는 것이다. 따라서 주부들이 운동을 계속하면 더 많은 제지방체중의 증가, 체지방률의 감소와 동시에 체중의 감소도 일어날 수 있으리라 기대된다. 일반적으로 체중 변인에 있어서 통제된 식이요법 및 자유로운 식이섭취 법이 커다란 비중을 차지하고 있는 바, 본 연구에서는 이러한 식이제한이 없는 상태에서의 운동처방만으로도 유의한 차는 없지만 체중 및 체지방률이 감소되었고 혈중지질 농도는 유의한 차로 변화가 나타났음을 알 수 있었다. 또한 에너지섭취량을 동시에 조사해본 결과 1일 에너지섭취량은 약 2.000ca1인 한국인 영양권장량의 권장 수준이었다. 따라서 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.

Two 15-week feeding trials were conducted to investigate how the rate and frequency of feeding affected the winter growth of olive flounder ($13^{\circ}C$). In the first experiment, triplicate groups of fish (initial mean weight $117{\pm}6.0$ g) were fed extruded pellets twice a day at feeding rates of 0.1, 0.25, 0.4, 0.55, and 0.57% (satiation) body weight per day (BW/d). The weight gain, specific growth rate, and feed efficiency increased significantly (P<0.05) with the feeding rates from 0.1 to 0.55% BW/d, but no significant differences in these parameters were found for fish fed diets of 0.55% BW/d and satiation. The moisture and ash contents of whole body of fish tended to decrease as the feeding rate increased, but the opposite trend was found for crude lipid content. In the second experiment, triplicate groups of fish (initial mean weight $117{\pm}6.3$ g) were fed extruded pellets to apparent satiation at the three different feeding frequencies: one meal 2 days, one meal a day and two meals a day. The weight gain and specific growth rate of fish fed one meal 2 days were significantly (P<0.05) lower than those of fish fed one or two meals a day, whereas no significant differences in the weight gain and specific growth rate were found between fish fed one and those fed two meals a day. Feed efficiency and condition factor were not significantly affected by feeding frequency. Based on these results, a feeding rate of 0.3% BW/d is recommended as maintenance feeding level, and the optimum feeding frequency is one meal a day with satiation feeding for the growth of olive flounder (117-147 g) during winter ($13^{\circ}C$).

주기적인 고온환경 부가와 백삼 및 홍삼 추출물의 투여가 흰쥐의 체중, 식이섭취량, 혈액성분, 장기중량 및 간의 지질과 산화에 미치는 영향을 살펴보았다. 흰쥐를 이용한 동물모델 실험결과, 매일 $38^{\circ}C$에서 5시간씩 7일간 고온환경을 부가한 경우 주당 평균체중 증가률이 감소하는 현상이 관찰되었으나 뚜렷한 식이섭취량 변화는 없었다. 반면 고온환경 부가전후에 백삼과 홍삼 추출물을 투여한 경우에는 고온환경 부가에 따른 평균 체중증가률 감소가 억제되었다. 고온환경 부가에 의한 혈액성분 변화를 살펴본 결과에서는 적혈구수와 혈색소량은 큰 차이를 나타내지 않았으나 백혈구수는 다소 증가하는 경향을 나타내었으며 인삼 추출물 투여는 백혈구수 증가도 억제하는 효과를 나타내었다. 고온환경 부가에 따라 장기중 간장의 중량비가 감소하였고 간의 MDA 함량이 크게 증가하였다. 인삼 추출물 투여시에 고온환경부가에 따른 간의 중량감소 및 MDA 함량 증가 등의 변화도 억제되는 효과가 있었다. 특히 간의 중량변화 및 간의 지질과산화 억제효과에 있어서는 백삼보다 홍삼 추출물의 효과가 다소 우수하였으며 통계학적으로 유의적인 수준은 아니었다. 향후 인삼중의 유효성분 구명이나 관련 물질들의 활성 변화에 대한 연구가 필요할 것으로 판단되지만 고온 등 급격한 주위환경가 변화에 대한 인삼의 생체항상성 유지효과를 일부 증명할 수 있는 결과인 것으로 판단되었다.

This study was conducted to investigate the effect of soybean peptide on muscle damage index and hormone (testosterone and cortisol) concentration. Subjects of this study were 23 high school male taekwondo players who had participated in regular exercise. They were randomly divided into two groups, one group took soybean peptide (S-peptide, n=13) 4 g a day for 4 weeks and the other took placebo (placebo, n=10) for the same time. We obtained blood samples before and after experiment and analyzed for CPK (Creatine phosphokinase), LDH (Lactate dehydrogenase), ALD (Aldolase), myoglobin, testosterone and cortisol. As for body composition, there was no significant difference in weight, body fat rate and LBM (lean body mass) between the S-peptide and the S-peptide group and placebo group. In CPK, LDH, ALD and myoglobin, S-peptide group was significantly lower than the placebo group and showed significant decrease before and after intaking soybean peptide (P<0.05~0.01). In the concentration of plasma testosterone, S-peptide group was increased from two weeks but not significant difference. The concentration of plasma cortisol showed significantly decrease in the S-peptide (P<0.01). These results indicate that the intake of soybean peptide have positive effect on index of muscle damage and changes of hormone concentration.

Objective : This study is conducted in order to investigate the effect of Banggibongnyeongtang(BBT) on Lipopolysaccharide (LPS)-induced depression. Method : LPS $5{\mu}g$ was injected to lateral ventricle. Experimental groups were administered BBT intraperitoneally. Depressive behavior was confirmed by weight change, sucrose preference, open field test(OFT), and forced swimming test(FST). The plasma concentration of $IL-1{\beta}$ and $TNF-{\alpha}$, Corticotropin-Releasing Factor(CRF), Adrenocorticotropin Hormone(ACTH) and Corticosterone(CORT) were measured by ELISA. Result : BBT did not change the body weight significantly than LPS group, but on sucrose preference, BBT increased significantly in LPS+BBT400 group compared to LPS group (P<0.05). In the OFT, BBT increased spending time in the central zone and decreased grooming number. LPS+BBT400 group increased central zone-spending time, and decreased grooming number than LPS group significantly (P<0.05). In the FST, LPS+BBT400 group decreased immobility time than LPS group significantly (P<0.05). BBT decreased $IL-1{\beta}$ concentration does-dependently, but only with significant decrease in LPS+BBT400 group than LPS group in plasma (P<0.05). But BBT did not decrease $TNF-{\alpha}$ concentration significantly in plasma. BBT decreased plasma CRF, ACTH, and CORT. And CRH and CORT of LPS+BBT400 group were shown significant decrease comparing with LPS group (P<0.05). Conclusion : It is postulated that the anti-depressant effect of BBT can be validated through inhibition of HPA axis abnormal activity by the anti-inflammatory effect.

Back ground and Objective : There is a need for objectification and scientific verification of Pattern identification in Oriental medicine. The purpose of this study was to investigate the skin characteristics of Qi deficiency and Blood deficiency animal models. Material and Methods : Sprague-Dawley rats were divided into three groups: normal group, Qi deficiency group and Blood deficiency group. The Qi deficiency animal model was induced through restriction of food (75g/kg/day) for 20 days. Blood deficiency animal model was induced by bleeding from tail vein(0.3 ml/time) 8 times. The normal animal model was kept without any intervention. The general condition was observed by measuring body weight, body temperature, blood pressure, pulse rate, and hematological and biochemical parameters. The skin characteristics were observed by measuring the erythema index(EI), melanin index(Ml), transepidermal water loss(TEWL) and dermal microcirculation. Results : 1. In the Qi deficiency group, body weight was lower than the other groups. In the Qi deficiency group, blood pressure was lower than in the Normal group. There was no difference in body temperature and pulse rate between the three groups. 2. In the Qi deficiency group, blood sugar was lower than in the Blood deficiency group. There was no difference in triacylglycerol between the three groups. In the Qi deficiency group, the WBC count was lower than in the Blood deficiency group. RBC count was highest in the Qi deficiency group, Normal group and Blood deficiency group respectively. In the Qi deficiency group, Hb and Hct were higher than the other groups. 3. EI and MI were decreased in the Qi deficiency group, and EI showed a significant decrease. 4. EI and MI were increased in the Blood deficiency group, and MI showed a significant increase. 5. TEWL was significantly increased in the Qi deficiency group, while it was decreased in the Blood deficiency group, TEWL was highest in the Qi deficiency group, Normal group and Blood deficiency group respectively and all three groups showed significant difference. 6. In the Qi deficiency group, dermal microcirculation was lower than the other groups. Conclusion : The above results show that the erythema index decreases in the Qi deficiency model, and the melanin index increases in the Blood deficiency model. The Qi deficiency animal model shows an increase in transepidermal water loss, while the Blood deficiency animal model shows a decrease. Further studies should develop new models of Pattern Identification that are more specific.
