  • A 25-week feeding trial of two dietary protein (47 and $52\%$) and three dietary lipid level (7, 12 and $17\%$) factorial design with three replications were conducted to determine effects of dietary protein and lipid levels on growth, feed utilization and body composition of adult starry flounder (Platichthys stellatus), average initial weight 332 g, during the winter season. Survival of fish was not affected by either dietary protein or dietary lipid level. Weight gain, feed efficiency and protein efficiency ratio improved with dietary protein and lipid levels except for those of fish fed the $52\%$ protein diet with $17\%$ lipid. The best growth and feed utilization were observed in the $52\%$ protein diet with $12\%$ lipid, but were not significantly different from those of fish fed the $52\%$ protein diet with $17\%$ lipid or the $47\%$ protein diets with $17\%$ lipid levels. Hepatosomatic and visceral somatic indexes were significantly influenced by dietary protein level, but not by dietary lipid level. None of moisture, crude protein, crude lipid, or glycogen contents of dorsal muscle or liver in starry flounder except for crude lipid in dorsal muscle was significantly influenced by either dietary protein or dietary lipid level. Plasma cholesterol concentration was significantly influenced by both dietary protein and dietary lipid levels. The results of this study suggest that the diets containing $47\%$ protein with $17\%$ lipid or $52\%$ protein with $12-17\%$ lipid are optimal for growth and feed utilization of adult starry flounder under these experimental conditions.

  • This study was designed to compare the effect of different dietary fats on plasma lipids, the degree of lipid peroxidation and the activity of antioxidant enzymes in RBC and liver rats treated with or wighout 1, 2-dimethylhydrazing (DMH). Male Sprague Dawley rats, at 7 weeks-old, were divided into control and DMH-treated grous, and each group was again subdivided into four were perilla oil (PO), blend fat (BF) containing ten different kinds of dietary oil, beef tallow (BT), corn oil (CO). At the same time, each rat was injected intramusculary with saline(for control) or DMH twice a week for 6 weeks to give total dose of 180 mg/kg body weight. Compared with BT feeding, BF reduced plasma total choesterol level and PO and Co reduced plasma TG levels (p<0.05). DMH injection decreased plasma cholesterol in all dietary groups. However, PO decreased tocopherol levels and increased TBARS levels in RBC compared to BT. The degree of hemolysis in PO group was higher than that of BT group (p<0.05 only in control group. Fatty acid composition of hepatic microsome was reflected by dietary fatty acid profile. The peroxidizability index and TBARS level in hepatic micorsome were significantly increased but tocopherol level was lowered in PO group compared to BT group. Activites of superoxide dismutase and glutathione peroxidase in RBC and hepatic cytosol were not influenced y dietary fats and DMH treatment(p<0.05). Overall, perilla oil rich in $\omega$3 $\alpha$-linolenic acid could be a very important dietary source in reducing plasma lipids and blend fat was also good dietary oil mixture in reducing plasma cholesterol. However, the degree of lipid peroxidation was greater in tissue by perilla oil feeding and it is very difficult to use only perilla oil as oil source for meal preparation, so that it could be suggested to use more perilla oil and fish to give an equal effect of blend fat in order to reduce the risk factors against cardiovascular disease.

  • This study designed to compare the hypolipidemic e(feats of n6 linoleic acid (LA), n3 w-linolenic acid(LL) and n3 eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA) In rats fed high fat (40% Cal) diet. Male Sprague-Dawley rats fed experimental diets for 6 weeks, which were different only in fatty acid composition. The dietary fats were beef tallow (BT) as a source of saturated fatty acid (SFA), corn oil(CO) for n6 LA, perilla oil (PO) for n3 a-LL and fish oil (FO) for n3 EPA+DHA. Plasma total cholesterol (T-chol) level was increased by n6 LA but decreased by n3 LL and n3 EPA+DHA and most effectively reduced by n3 EPA+DHA. Plasma triglyceride(TG ) level was reduced by n6 LA, but lipogenesis in liver was not affected by n6 LA. However, plasma TG level was lowered by n3 LL and EPA+DHA. Both lipogenic enzyme activity and liver TG level were also decreased by n3 PUFA. PO and FO groups were significantly higher in the relative Proportions of C20:5 and C22:6 of plasma and liver and lower in those of C20:4/C20:5 ratio. Overall, the lipid-lowering effect was in the order of n3 EPA+DHA >n3 LL > n6 LA and fish oil and perilla oil rich in n3 PUFA may have important nutritional applications in the prevention and treatment of hyperlipidemia.

  • Regular exercise training improves body composition, blood lipid profiles and exercise adaptation. This study was conducted to investigate the effect of exercise training at different times of day on body composition, blood lipids, stress hormones and nutrient intakes. Twenty four male graduate students carried out this experiment. The subjects were divided into three groups; morning exercise group, evening exercise group and control group. Two exercise groups performed running and muscular resistance training at mid intensity for 12 week periods. Body composition, blood lipid profiles, blood cortisol, ACTH and nutrient intakes were analyzed prior to, midway and after training. There were significant differences about interaction between different exercise times and training periods in plasma TG and HDL-C of the evening exercise training (p < 0.05). Also the evening exercise group was showed the decreasing of TC after training (p < 0.05). No significant differences about interaction between different exercise times and training periods were shown in body composition, stress hormones and nutrient intakes in the three groups. But evening exercise training decreased body fat ($\%$) and blood ACTH (p < 0.05). Also the increasing of carbohydrate intakes was shown by the evening exercise training (p < 0.05). In contrast, morning exercise group indicated a decrease of body fat ($\%$) after 6 week training (p < 0.05), but this effect was not maintained after 12 weeks of training. These results suggested that regular evening exercise is more effect than morning exercise from the viewpoint of improving body composition, blood lipids, nutrient intakes and exercise adaptation.

  • Objectives The purpose of this study was to investigate the effects of Cheunggihwadamhwan (CGHDH) extract on lowering lipid, antioxidation and production of proinflammatory cytokines in rats fed on high fat diet. Methods 40 Male Sprague-Dawley rats were fed on high fat diet for 8 weeks and 32 rats (above 400 g) were randomly divided into 4 groups (8 mice in each group) : control group, 100 mg/Kg CGHDH group, 200 mg/Kg CGHDH group, 300 mg/Kg CGHDH group. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1 time/1 day) for 4 weeks. And We fed each experimental group of rats basal diet and administered an extract of Cheunggihwadamhwan extracts (100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid in plasma and liver, concentration of proinflammatory cytokines, antioxidative activity and gene expression. The gene expression level was investigated by the way of reverse transcription-polymerase chain reaction (RT-PCR). Results 1. Concentration of plasma FFA, plasma TG, plasma total cholesterol and plasma LDL-cholesterol showed a significant decrement in Cheunggihwadamhwan groups. However, concentration of plasma HDL-cholesterol showed a significant increment in 200, 300 mg/kg Cheunggihwadamhwan groups. 2. Concentration of liver total cholesterol and liver TG showed a significant decrement in Cheunggihwadamhwan groups. 3. Concentration of plasma TBARS showed a significant decrement in all Cheunggihwadamhwan groups. Concentration of liver TBARS showed a significant decrement in 200, 300 mg/kg Cheunggihwadamhwan groups. Concentration of liver GSH-Px, SOD and CAT showed a tendency to decrease in all Cheunggihwadamhwan groups. 4. Concentration of plasma IL-$1{\beta}$, plasma IL-6, TNF-$\alpha$ and NO, showed a tendency to decrease in all Cheunggihwadamhwan groups. Concentration of plasma IL-10 showed a tendency to increase in all Cheunggihwadamhwan groups. 5. In the analysis of reverse transcription-polymerase chain reaction (RT-PCR), the gene expression of Apo-B and Apo-E in the Cheunggihwadamhwan groups showed a low expression than that of control group. The ratio of Apo-B expression per $\beta$-actin expression in the showed a significant decrement in all Cheunggihwadamhwan groups. The ratio of Apo-E expression per $\beta$-actin expression in the showed a significant decrement in 300 mg/kg Cheunggihwadamhwan groups.

  • 국소접착인산화효소(FAK)는 국소접착부에서 세포부착, 세포이동, 세포역학적 신호전달 등에 관여한다고 알려져 있다. 그러나 세포 외 기질(ECM)과 상호작용하는 인테그린 막단백질과 함께 위치하는 세포막 미세영역(membrane microdomain)의 종류와 ECM 구성에 따른 FAK 활성은 여전히 불분명하다. 형광 공명 에너지 전달(FRET)을 기반으로 유전적으로 인코딩 된 바이오센서는 세포 내 FAK 신호를 높은 시공간 해상도로 제공할 수 있다. 본 연구에서는 유리, 제1형 콜라겐, 피브로넥틴, 라미닌의 ECM 조건에서 FRET 기반 막 표적 FAK 바이오센서를 사용하여 지질유동섬(Lipid raft) 및 비-지질유동섬(non-Lipid raft)에서 FAK의 활성을 분석하고 시각화 하였다. 흥미롭게도, 지질유동섬에서 라미닌 조건 하의 FAK 활성은 다른 ECM 조건보다 낮았고, 비-지질유동섬에서 FAK 활성은 다른 ECM 조건보다 낮았다. 동일한 ECM 조건 상의 비교에서는 피브로넥틴 조건일 때 지질유동섬에서 비-지질유동섬 보다 높은 FAK 활성이 관측되었다. 따라서 이번 연구는 FAK 활성도가 ECM 유형 및 세포막 미세영역에 따라 특이적으로 조절되는 것을 시각적, 정량적으로 보여준다.
