Ten college women were divided into 5 groups and treated in randomized block design for 5 weeks with 1 interval between treatments and subjects serving as their own controls. The experimental diets were corn oil diet as a source of n-6 linoleic acid, perilla oil diet as a source of n-3 $\alpha$-linolenic acid, and fish oil diet as a source of n-3 EPA and DHA. Dietary fat was supplied at 30% Cal and modified to give the total amount of saturated fatty acids and monoenoic acids at constant level. There was no significant effect on serum cholesterol level by different PUFA. However, on a gram-for-gram basis, there was a trend that the decrease in serum cholesterol was proportionate to the degree of fat unsaturation. On the other hand, only fish oil diet significantly decreased TG level but no significant effect on the relative proportion of TG in VLDL. The degree of hypotriglyceridemia did not corrleate with the degree of unsaturation. The relative proportion of CE in LDL was reduced by all PUFA diets but significant only by perilla oil diet. The relative amount of apoprotein in LDL was significantly reduced by n-3 PUFA. HDL-Chol content was significantly increased only in fish oil diet but no change in the relative proportion of its chemical components of HDL.

Recently, the use of antibiotics to improve animal productivity in livestock industry was strictly restricted. For these reason, probiotics have been regarded as one of promising materials for an antibiotic alternative. In this study, we investigated how the probiotics influences on the performance of broiler chicken via meta-analysis. Eighteen researches from 1997 to 2010 were used for meta-analysis. The standard summary effects were calculated via fixed effect model and random effect model (Borenstein et al., 2009). Heterogeneity was calculated by using the Cochran's Q statistics (Kook et al., 2009) and publication bias was calculated via Egger's regression (Lee et al., 2011). In fixed model average daily gain, body weight serum protein content and cecal LAB showed positive effect significantly. Feed intake, feed/gain and serum cholesterol showed significant negative effect. In serum triglyceride, negative effect was found but significance was not shown. In random model, average daily gain body weight and cecal LAB showed positive effects with significance and feed/gain and serum cholesterol represented significant negative effects. Publication bias was found only in feed/gain.

This study was performed to investigate the effect of Lycii fructus beer on serum lipid profiles and antioxidant activity in rat Sprague-Dawley (SD) rats weighting about 190g were divided into the following 5 groups ; distillate water (Control), 5% ethanol in distillate water (Ethanol), commercial beer (CB), Lycii fructus beer (LFB) and 5% alcohol red wine diluted with distillate water (RW). Body weight, total food intake, FER and percent organ (liver, kidney) weight per body weight were not significantly changed by Lycii fructus beer drinking. After 6 weeks, serum total cholesterol, triglyceride and HDL cholesterol level were not significantly different. But, Lycii fructus beer intake tended to decrease serum triglyceride level and atherogenic index. Also, GOT and GPT levels were expressed lower than Ethanol group. There was not significantly different in hepatic glutatiione (GSH) content and glutathione-S-transferase (GST) activities among 5 groups. Lipid peroxidation in the hepatic was decreased by Lycii fructus beer intake. The results demonstrated that Lycii fructus beer was potential and effective antioxidant that can protect the decrease associated with alcohol.

섬애약쑥 가공품 개발 및 그 활성 규명을 위한 연구의 일환으로 섬애약쑥 물 추출물을 이용하여 식혜를 제조해 당화시킨 후 알코올 발효와 초산발효를 차례로 거쳐 식초를 완성하였다. 고지방-고콜레스테롤 식이를 제공한 흰쥐에 섬애약쑥 식초를 경구 투여하여 체내 지질대사에 미치는 영향을 분석하였다. 실험군은 일반식이를 급이한 정상군(N), 고지방-고콜레스테롤 식이를 급이한 대조군(C), 대조군 식이 급이 후 콜레스테롤 치료 약물인 lovastatin을 20 mg/kg B.W. 투여한 양성대조군(PC), 섬애약쑥 추출물 대신에 물을 첨가하여 동일하게 제조한 맥아식초(TM)와 섬애약쑥 식초(TS)를 체중 kg당 2 mL씩 경구 투여한 군으로 나누었다. 4주간의 실험식이 급이 후 혈청 내 총 지질과 총 콜레스테롤 함량은 식초 급이군이 양성대조군보다 유의적으로 낮았으나 중성지질은 양성대조군과는 유의적인 차이가 없었고 대조군 보다는 유의적으로 낮았다. HDL-콜레스테롤은 식초 급이군과 양성대조군 간에 유의적인 차이 없이 정상군보다 낮았으나 대조군보다는 유의적으로 높았다. LDL-콜레스테롤은 섬애약쑥 식초 급이군에서 190.68 mg/dL로 정상군을 제외한 실험군 중 가장 낮은 함량이었고 동맥경화지수와 심혈관계 질환 위험지수도 동일한 경향이었다. 혈청 총 단백질과 알부민 함량은 맥아식초와 섬애약쑥 식초 급이군이 대조군이나 양성대조군보다 유의적으로 낮았다. 간 손상 지표가 되는 AST는 정상군과 식초 급이군 간에 차이가 없었다. 섬애약쑥 식초의 급이는 간장 내 지질 농도 개선에도 효과가 있어 간장 내 총 지질, 총 콜레스테롤 및 중성지질의 농도를 대조군보다 유의하게 감소시켰다. 혈청 내 지질과산화물의 함량은 섬애약쑥 식초 급이군에서 정상군과 유사한 수준으로 감소하였으며, 간 조직에서는 대조군보다는 낮았으나 정상군보다는 유의적으로 높은 함량이었다. 이러한 결과는 DPPH를 이용한 항산화 활성 평가에서도 유사한 경향으로 섬애약쑥 식초 급이군 혈청의 항산화 활성이 55.69%로 정상군과 유의차가 없었으며, 간 조직의 활성은 52.39%로 대조군과 유의적인 차이가 없었다. 이상의 결과로부터 섬애약쑥 식초는 혈중 지질 농도를 개선하는 효과가 있음을 확인하였으며, 이는 식초 자체의 활성과 자체에 함유되어 있던 유효성분 및 발효과정에서 새로이 생성된 성분들이 복합적으로 작용한 결과로 판단된다.

This study aimed to assess the effects of neutral detergent fiber (NDF) from rice straw on blood metabolites and productivity of dairy cows in the tropics. Eight Holstein ${\times}$ indigenous (75-87.5% Holstein) were randomly allocated to dietary treatments according to a double $4{\times}4$ Latin square design. Contents of roughage NDF from rice straw were 12.8, 14.8, 16.8 and 18.8% dry matter (DM) and concentrate NDF content was 10.2% DM, so that levels of dietary NDF were 23, 25, 27 and 29% DM. Dietary treatments were isonitrogenous and isocaloric diets. The average maximum and minimum temperature humidity index during the experimental period were 85.6 and 76.9, respectively. Plasma glucose (p<0.05), dry matter intake and 4% fat corrected milk (p<0.01) decreased with increasing contents of roughage NDF from rice straw, while rectal temperature, serum urea, cortisol, low density lipoprotein-cholesterol (p<0.05), serum total protein and ${\beta}$-hydroxybutyrate (p<0.01) increased. Serum triglyceride, total cholesterol and high density lipoprotein-cholesterol were not affected (p>0.05). Decreased rectal temperature and concentrations of serum cortisol were associated with decreasing levels of ${\beta}$-hydroxybutyrate and serum urea, but with increased concentrations of plasma glucose, DMI and 4% fat corrected milk indicating that lactating cows fed lower fiber diets were in lower oxidative stress. Therefore higher intake and metabolic efficiency in dairy cows fed diets lower in roughage NDF from rice straw would be of an advantage in productive systems under tropical conditions.

Male rats of 2 months-old(young), 6 months-old(adult) and 30 months-old(old)were fed 8 or 16 weeks to investigate the e(feats of dietary fat level on the lipid metabolism in the different stages of aging. The response of 30 month old rats to dietary fat level differed from either 2 or 6-months old rats. In 30-months old rats, dietary fat level had a little effect on weight gains, lipid content of serum as compared with other two age groups. Young rats showed higher body weight gain, F.S.R, and PER compared with aged rat. The younger and the more high fat fed the rats were, the more body weight gains, FER and PER showed. Weight of liver and kidney was increased in aged rats but ratio per unit weight of liver and kidney was not affected by age. Serum lipid content was higher in aged rat compared with the young and liver lipid content was higher in high fat diet fed rats. But TG of liver and serum was not changed with aging process. Intake, excretion and absorption of lipid was not changed by age of animals. but absorption was decreased as experimental period was increased.

This study was performed to investigate the risk factors for coronary heart disease in elderly women. Seventy five elderly women over 65 years of age participated with 35 elderly men over 65 years of age, 40 middle-aged men and 31 middle-aged women as control subjects. The percentage of body fat(34.1 5.6%) in elderly women found to be significantly higher than in other groups and their waist/hip circumference ratio(WHR) was higher than in middle-aged women. The concentrations of plasma total cholesterol and LDL-cholesterol in elderly women were higher than in other groups, TG concentration higher than in middle aged women and HDL-cholesterol % lower than in other groups. Plasma cholesterol ester transfer protein(CETP) activities of elderly women were significantly higher than in middle-aged subjects, but were not different from those of elderly men. Plasma Apolipoprotein(Apo) A-I level in elderly women was higher than in middle-aged men but not different from the other groups. Differences among groups were not great in Lipoprotein (Lp)(a)levels. CETP activities were significantly correlated with age, body fat % total cholesterol, LDL-cholesterol and Lp(a). Therefore, it appears that the increased risk of coronary heart disease in elderly women is due to the increase of body fat, central adipose distribution, serum total cholesterol, LDL-cholesterol and CETP activities.

갱년기의 여성에는 여러 폐경 증후들이 나타나는데, 특히 에스트로겐의 감소로 인한 혈중의 지질 조성의 변화 등으로 심혈관계 질환의 발병율이 높아지게 된다. 이러한 폐경기의 문제를 감소시키기 위하여 호르몬 보충요법이 사용되고 있으나 유방암, 관상동맥질환 등을 오히려 증가시키는 등의 보고가 있다. 따라서 해조류 중에서 갈조류인 대황 추출물을 이용하여 갱년기 유도 흰쥐의 혈중지질 농도, 혈소판 응집력 및 혈액 유동성을 통하여 그 효과를 검토하고자 하였다. 또한 동물실험에 이용하기 위한 추출물 제조 방법으로는 열수와 에탄올을 이용하는 것이 일반적이므로, 이러한 추출 방법으로 추출물을 제조한 후 항산화 활성을 측정하여 활성이 우수한 추출물을 본 실험에 이용하고자 하였다. 실험 결과 갱년기 유도로 인하여 증가된 혈청 중 중성지방 및 총콜레스테롤 함량은 대황 추출물 투여에 의해 저하되었으며, 특히 대황 추출물 200 mg/kg bw/day 투여는 중성지방 함량을 유의적으로 감소시키는 결과를 나타내었다. AI와 CRF는 난소를 절제한 OVX-CON군이 난소를 절제하지 않은 SHAM군 보다 유의적으로 증가하는 결과가 나타났으나, 대황 추출물의 투여에 의해 유의적으로 감소하였다. 또한 대황추출물의 항 혈전능에 미치는 영향을 검토하기 위해, 난소절제로 인하여 혈 중 지질 함량이 증가한 상태에서 washed platelet을 분리하고 콜라겐 2 ${\mu}g$으로 혈소판 응집을 유도하였다. 그 결과 대황 추출물을 투여한 군이 OVX-CON군에 비해 혈소판 응집을 억제하는 것으로 나타났다(Table 5). Amplitude (%)는 난소절제를 한 OVX-CON군이 난소절제를 하지 않은 SHAM군과 비교하여 증가하였으나, 대황 추출물 투여군인 OVX-EB50 및 OVX-EB200군 모두에서 감소하는 경향을 나타내었다. 난소절제로 인해 OVX-CON군이 비 난소절제군인 SHAM군과 비교하여 Slop이 증가하여 혈소판 응집이 촉진되었으나, 대황 추출물 투여에 의해 감소하였고 특히 OVX-EB50군에서 유의적으로 감소하여 혈소판 응집이 억제되었다. 응집시간을 나타내는 lag time (sec)은 난소절제에 의해 반응이 일어나는 시간이 짧아져, 혈소판 응집이 촉진되는 결과가 나타났다. 이에 반해 대황 추출물 투여군인 OVX-EB50 및 OVX-EB200군에서 응집시간이 지연되었으며, 특히 OVX-EB200군의 경우 정상군인 SHAM군과 같은 응집지연 효과를 보였다. 한편, 대황 추출물이 혈액의 유동성에 미치는 영향에 대한 실험 결과 난소절제에 의해 혈액의 점도가 증가하여 유동성이 저하되었으나, 대황 추출물 투여에 의해 유동성이 향상됨을 알 수 있었다. 따라서 대황 추출물이 외부자극으로 인한 혈소판 응집능이나, 점도의 증가로 인한 혈액의 유동성에 효과적인 것으로 보여진다. 따라서 이상과 같이 대황 추출물이 혈중 LDL-콜레스테롤, AI 및 CRF를 감소시키고, 혈액 유동성을 증가시키는 결과로부터 심혈관 질환의 위험율을 저하시킬 수 있는 소재가 될 것으로 기대가 되나, 앞으로 투여량의 범위 및 조절 등의 구체적인 연구가 요구된다.
