The purpose of this study was to investigate the effect of medical nutrition therapy (MNT) on anthropometric measurements, quality of diets, and blood parameters through the weight loss program in over weight or obese women. The subjects (n=76, $age\;31.1{\pm}8.4y,\;weight\;70.3{\pm}7.9kg,\;BMI\;27.2{\pm}2.4kg/m^2$) without medical disease were treated with MNT 5 times for 12 weeks by dietitian. Anthropometric measurements included height, weight, fat mass, lean body mass, triceps and thigh skin-fold thickness, mid-arm, waist, hip and thigh circumference. Dietary assessments were accomplished using 3-days food records, diet quality index (DQI), and dietary pattern. The dietary pattern was assessed by daily energy intakes from breakfast, lunch, dinner, and snacks of calorie density, and numbers of eating. Blood levels of leptin, lipid profiles (total lipids, total cholesterol, LDL-cholesterol, HDL-cholesterol), and insulin were analyzed. Anthropometric measurements decreased significantly after MNT (p<0.001). Waist circumference was reduced most rapidly and tricep skin-fold thickness was reduced most effectively after 12 weeks of MNT. Daily energy intake, calorie density and numbers of eating incidence decreased significantly $0796.4{\pm}395.5\;vs\;1402.9{\pm}217.8\;kcal/day,\;162.3{\pm}56.5\;vs\;113.4{\pm}30.1,\;5.0{\pm}1.4\;vs\;3.8{\pm}0.4$, respectively, p<0.05). The daily energy intake from breakfast and snacks significantly decreased (p<0.001). Calories from snack, calorie density of snack and numbers of snacking also decreased (p<0.05). The mean scores of DQI significantly increased ($7.6{\pm}2.1\;vs\;6.5{\pm}1.6$, p<0.05). The plasma levels of total lipid, triglyceride (TG), total cholesterol, LDL-cholesterol and leptin decreased significantly after MNT ($489.8{\pm}100.4\;vs\;447.0{\pm}87.3mg/dL,\;187.7{\pm}34.0\;vs\;175.9{\pm}31.5mg/dL,\;115.2{\pm}29.2\;vs\;109.2{\pm}26.7mg/dL,\;15.7{\pm}7.6\;vs\;12.4{\pm}5.9ng/mL$, respectively, p<0.05). These results indicate that MNT efficiently reduced the body weight through the changes in dietary intake, dietary patterns and dietary quality. MNT also changed body composition and reduced the levels of plasma lipid, cholesterol and leptin.

인체의 혈장 저밀도 지단백(LDL)은 관상동맥경화 발병의 주 요인이다. 그러나 최근의 연구들은, 정상적인 LDL은 산소 자류라디칼에 의해 쉽게 산화되며, 결과 LDL 수용채와 결합하지 못한다고 밝히고 있다. 따라서 이 변형된 형태의 산화된 LDL은 macrophage scavernger receptor에 의해 인식되어 foam cell을 형성하여, 동맥혈관이 좁아지는 역할을 수행한다고 알려지고 있다. 지리과 산화에는 지방산이 중요한 작용을 하므로, 한국인의 LDL의 지방산 조성을 분석하여 서양인과 비교하였다. 결과, 한국인의 불포화 지방산의 비율이 총 지방산 함량의 약 30%인 반면 서양인은 약 70%의 분포를 갖고 있는 것으로 발표되었다. 따라서 한국인이 서양인에 비해 LDL의 산화에 대한 영향을 적게 받을 수 있으며, 따라서 동맥경화나 심장병의 발생률이 훨씬 적을 것으로 결론을 내릴 있다. 정상적인 LDL을 황산구리와 함께 배양하여, 지방의 산화를 유도하였으며 이의 정도를 지방산 산화의 생성물인 TBARS를 측정하여, LDL이 산화될 때 생성되는 자유라디칼의 양을 측정하므로서 비교하였다. 이 때, 항상화제인 비타민 C; 비타민 E와 히알우로닉산을 첨가하면 LDL의 산화가 억제되는 효과를 확인하였다. 자유 라디탈이 증가함에 따라 산화의 정도도 증가하였으며, 자유라디칼 형성의 경시적 변화는 TBARS와 유사하였다. 따라서 luminometer에 의한 자유라디칼의 정량은 TBARS에 의한 것보다 훨씬 간편한 것으로 나타났다.

표고버섯과 보리에서 추출한 ${\beta}-glucan(M500,\;B500)$을 Alloxan으로 당뇨를 유발시킨 6주령의 ICR 마우스에 10 일간 경구 투여를 실시하고 식이 섭취량 및 체중의 변화를 관찰하고 혈액중의 포도당 농도, 혈액과 간장 중의 지질 성분 및 각종 장기의 무게 변화를 측정하였으며 결과는 다음과 같다. Alloxan 유발 당뇨 마우스에서 B500군과 M500군은 정상대조군에 비해 거의 2 배에 가까운 식이 섭취량이 관찰되었으나 이에 따른 체중 변화는 시료 투여군에서 당뇨 대조군과 정상 대조군보다 유의적으로 체중이 감소하는 경향을 보였다(p<0.05). 혈중 포도당 농도는 당뇨 대조군의 경우 실험기간 시작부터 종료시까지 고혈당을 유지하였으나, B500군과 M500군은 당뇨 대조군에 비해 유의적으로 낮은 혈당치를 나타내었다(p<0.05). 혈중 중성지방 함량은 당뇨 대조군이 정상 대조군에 비해 약 1.7배 정도 증가하였다. B500군은 당뇨 대조군에 비해 중성지방의 농도가 유의적으로 감소하였으나, M500군에서는 유의적인 차이가 없었다(0.05). 혈액중 총 콜레스테롤 농도와 LDL 콜레스테롤 농도는 각 군에서 유의적인 차이를 보이지 않았다. 이상에서 표고버섯과 보리의 ${\beta}-glucan$을 Alloxan 유발 당뇨 마우스에 투여하였을 때 체중 및 혈중 포도당 농도가 감소되었고, 특히 보리 ${\beta}-glucan$은 혈중 중성지방 농도를 감소시키는 경향을 보였으므로 표고버섯과 보리의 ${\beta}-glucan$이 당뇨병에 대한 개선 효과가 있다고 인정되며 이를 이용한 기능성 식품으로의 개발 가능성이 높다고 사료된다.

Twenty college women were led experimental diet which composed ot basal diet plus different kinds of dietary rats at 27% Cal. Equal amount of 13.5g of corn oil, perilla oil or fish oil was supplied for 2 weeks as a source of n6 linoleic acid(LA). n3 $\alpha$-linolenic acid (LL). or n3 EPA + DHA. respectively. Plasma total Chol level was reduced by perilla and fish oils, significantly only by fish oil. Plasma Chol level was rather increased by corn oil(P<0.05), but was decreased by double amount of corn oil supplement. Therefore, hypocholesterolemic effect of fatty acids was in the order of n3 EPA+DHA>n3 LL>n6 LA and influenced by the degree of fat unsaturation. Plasma TG level was also significantly decreased by n3 EPA+ DHA and increased by n6 LA. Hypotriglyceridemic effect of fatty acids was also in the order of n3 EPA + DHA> n3 LL>n6 LA and influenced by the unsaturation. However, the reduction of plasma TG was more influenced by the fatty acid structure rather than the fat unsaturation. There were no significant effects on lipoprotein pattern 3nd chemical compositions of lipoprotein by different dietary PUFAs. but fish oil diet significantly increased the relative proportion of HDL-Chol. In conclusion. cholesterol- lowering effect of dietary PUFAS seemed to be a function of total fat unsaturation but hypotriglyceridemic effect seemed to be more linked to the ratty acid structure rather than the degree of unsaturation. The hypolipidemic effect of n3 PUFAs was significant so that fish oil or perilla oil may have important nutritional applications in the prevention and treatment of atherosclerotic disease.

To study the acute effect of dietary docosahexaenoic acid (DHA, $C_{22:6}$) on the expression of adipocyte determination and differentiation-dependent factor 1 (ADD1) mRNA in pig tissues, weaned, crossbred pigs (28 d of age) were fed with either 10% (on as-fed basis) tallow (high stearic acid), soybean oil (high linoleic acid), or high DHA algal oil for 2 d. The plasma and liver DHA reflected the composition of the diet. The adipose tissue and skeletal muscle DHA did not reflect the diet in the short term feeding. The results also showed that the diet containing 10% algal DHA oil significantly decreased the total plasma cholesterol (39%) and triacylglycerol (TG; 46%) in the pigs. Soybean oil significantly decreased plasma TG (13.7%; p<0.05), but did not have an effect on plasma cholesterol. The data indicate that different dietary fatty acid compositions have different effects on plasma lipids. The ADD1 mRNA was decreased (p<0.05) in the liver of DHA oil-treated pigs compared with the tallow-treated pigs. The diets did not have significant effect on the ADD1 mRNA in adipose tissue. Addition of algal DHA oil in the diet increased acyl CoA oxidase (ACO) mRNA concentration in the liver, suggesting that dietary DHA treatment increases peroxisomal fatty acid oxidation in the liver. However, dietary soybean oil supplementation did not affect mRNA concentrations of ADD1 or ACO in the tissues of pigs. Because ADD1 increases the expression of genes associated with lipogenesis, and ACO is able to promote fatty acid oxidation, feeding DHA oil may change the utilization of fatty acids through changing the expression of ADD1 and ACO. Therefore, feeding pigs with high DHA may lead to lower body fat deposition.
