This study was conducted to examine the effect of dietary iron levels on lipid metabolism, antioxidative and antithrombogenic capacities in 16-month-old rats. Thirty-two Sprague-Dawley male 16-month-old rats weighing 618 $\pm$ 6 g were raised for 10 days with medium-iron diet (35 ppm in diet) and blocked into 4 groups according to their body weights. One of groups was sacrificed to obtain initial data and the rest 3 groups were raised for 3 months with experimental diets containing different levels of iron (5 ppm, 35 ppm, and 350 ppm). Total lipid, triglyceride and total chole-sterol concentrations in plasma and liver, HDL-cholesterol concentration in plasma, fecal total lipid triglyceride and total cholesterol excretions, thiobarbituric acid reactive substances (TBARS) level in plasma LDL + VLDL (low density lipoprotein + very low density lipoprotein) fractions, blood-clotting time and eicosanoids levels in plasma were measured. The results are as follows: Plasma total lipid, triglyceride and total cholesterol concentrations, TBARS level in plasma LDL + VLDL fractions were increased and blood-clotting time tended to be shortened during 3 months of experimental period. Low (5 ppm) iron diet improved lipid metabolism via increasing HDL-cholesterol and fecal choles-terol excretion. High (350 ppm) iron diet decreased plasma total lipid, triglyceride and total cholesterol concentrations as compared to medium (35 ppm) iron diet and lowered body weight and epididymal fat pad weight. On the other hand, TBARS level in plasma LDL + VLDL fractions and blood-clotting time were increased with high iron diet. It is plausible that low iron diet improves lipid metabolism, antioxidative and antithrombogenic capacities in 16-month-old rats.

This study investigated the effects of cod liver oil and chromium picolinate on the serum traits and egg yolk fatty acids and cholesterol content in laying hens. One hundred 45-week old single comb white Leghorn laying hens were assigned randomly to four groups. These groups were: (1) control (soybean oil), (2) 1,000 ppb (${\mu}g/kg$) chromium (organic form chromium picolinate) (Crpic), (3) 3% cod liver oil (CLO), and (4) 1,000 ppb chromium with 3% cod liver oil (CLO+Crpic). The experiment was conducted for 40 days. Results indicated that serum triacylglycerol (TG) and cholesterol contents in the CLO group and the serum glucose content in the Crpic group were significantly lower than those in the control group (p<0.05-0.01). The yolk cholesterol content in the CLO and Crpic groups were also lower than the control group (p<0.01). The lipoprotein profile displayed that in the Crpic group, high-density lipoprotein (HDL) and HDL-cholesterol (HDL-C) were significantly higher (P<0.05) than the control group. Meanwhile, low-density lipoprotein+very low-density lipoprotein (LDL+VLDL) and LDL-C+VLDL-C were significantly lower (p<0.05) than the control group. Notably, of all four groups, the CLO group displayed a more profound effect on serum traits and lipoprotein (p<0.05-0.001). Furthermore, the fatty acid composition of the egg yolks presented that C18:2 in the CLO and Crpic groups was significantly lower (p<0.05-0.001) compare to the control. However, only in the CLO group, C18:3, C20:5 and C22:6 were significantly higher (p<0.001) than the control. Only serum glucose and LDL+VLDL showed the CLO${\times}$Crpic interaction (p<0.05), most parameters did not. Therefore, supplemented chromium picolinate or cod liver oil in the diet of laying hens had beneficial effects. However, when these two factors were combined, there was no interaction with most parameters.

We conducted two experiments to evaluate effects of feeding various types of red ginseng marc and Houttuynia cordata (H.cordata) on blood profiles of poultry in a completely randomized design. In experiment 1 (28 d), a total of 240 broilers (Arbor acres) were used. Four dietary treatments (15 broilers per pen with four replicate pens per treatment) were included: (1) control, (2) 2% red ginseng marc, (3) 1% fermented red ginseng marc with red koji, and (4) 2% liquid red ginseng. There were no significant differences in HDL and LDL-cholestrol among treatments (P > 0.05), but total cholesterol and triglyceride decreased in diets supplemented with red ginseng marc and 1% fermented red ginseng marc with red koji compared to that in the control treatment (P < 0.05). In experiment 2 (38 d), a total of 240 Pekin ducks were randomly divided into 4 groups by dietary treatments (control, 1% fermented H. cordata powder with red koji, 1% fermented H. cordata pelleted with red koji, and 1% fermented H. cordata coated with red koji) with 4 replicates of 15 ducks in each group. Total cholesterol and VLDL-cholesterol were not affected by diet with various types of H. cordata. However, increase in HDL-cholesterol and decrease in LDL and VLDL-cholesterol were greater in treatments with different types of H. cordata than in the control treatments (P < 0.05). In conclusion, using various types of red ginseng marc and H. cordata in poultry diets was effective for increasing HDL-cholesterol and decreasing total, LDL, and VLDL-cholestrol or triglyceride.

This study was to compare the effects of dietary n-6 and n-3 fatty acids and fat unsaturation on plasma lipids and chemical composition of VLDL and LDL fraction and lipogenic enzymes activity in rat liver under the conditions providing 1) a similar amount of n-6, n-3 fatty acids(LA, ALA, EPA+DHA) in diets and 2) the various degree of fat unsaturation. Male Sprague-Dawley rats weighing 420g were treated for 6-n with six experimental diets providing 25% of energy as fat and which were different only in fatty acid composition. The fats used for a source of each fatty acid were beet tallow for saturated fatty acid corn oil for n-6 linoleic acid(LA) perilla oil for n-3 $\alpha$-linolenic acid(ALA) and fish oil n-3 eicosapentaenoic acid (EPA) and n-3 docosahexaenoic acid(DHA). Plasma cholesterol level was increased by corn oil to compare with beef tallow but was decreased by perilla oil or fish oil. Plasma TG level was significantly decreased by perilla oil or fish oil. Fish oil significantly reduced the level of HDL-Chol and the proportion of Chol in LDL fraction and that of TG in vVLDL fraction. Overall there was a singificant negative correlation between the level of each plasma lipid(Chol TG, VLDL-TG, LDL-C) and the degree of fat unsaturation. However this rerlationship is not always true when compared the hypolipidemic effect of each fatty acid at a similar level of fat unsaturation. There was a trend such taht glucose 6-P dehydrogenase 6-phosphogluconate dehydrogenase and malic enzyme activites were reduced by n-3 fatty acids. Perilla oil significantly increased the incorporation of c20:5 and c22:5 into liver tissue and fish oil suignificantly increased the incorporation of c20:5, c22:6 into liver tissue and the effect of long chain n-3 fatty acid incorporation was greater by fish oil. therefore the hypotriglyceridemic effect of n-3 fatty acid could be resulted from the interference of hepatic lipogenesis by long-chain n-3 fatty acids and the reduced proportion of TG in VLDL fraction and its effect was greater by n-3 EPA+DHA than n-3 ALA even though plasma Chol and TG levels were also influenced by the degree of dietary fat unsaturation.

This study was carried out to determine, the effects of sodium alginate and cellulose on the plasma lipoportein composition and cholesterol metabolism inrats.Each experimental diet contained 105 sodium alginate and cellulose by weight, respectivley and rats were fed fro 4 weeks. The results obtained were as follows : The feeding of sodium alginate and cellulose decreased total plasma cholesterol slightly . total cholesterol of Chylomicron /VLDL- , LDL-fraction and liver were decreased significantly insodium alginate group. HDL-cholesterol was slightly increased in soidum alginate group. The feeding of sodium alginate significantly lowered plasma , Chylomicron VLDL-, LDL-fraction and liver TG concentrations compared with those fed fiber-free diet . The HMG-CoA reductase activity was not different among diet groups but the lowest activity was observed in sodium alginate group. The feeding of sodium alginate significantly increased fecal cholesterol , TG, and bile acid excretion . In summary , the ingestion of sodium alginate decreased cholesterol and TG concentrations of plasma and liver. This may be explained by the facts that fecal cholesterol, bile acid and TG level were increased significantly in sodium alginate group.

The influence of the ditary containing boiled eggs on the plasma cholesterol level and antithrombotic activity in rats was studied. Rats were fed basal diet(0% boiled eggs) as a control group or diets containing 25% and 50% boiled eggs or a mixed diet with 95% boiled eggs plus 5% $\alpha$-cellulose powder as a experimental groups for 30 days. The bleeding time and whole blood clotting time were significantly(P<0.05) increased by feeding diet containing 25% boiled eggs compared to groups of basal diet, 50% or 95% boiled eggs diets. The plasma clotting time was high in group of 25% boiled eggs diet. However, there were no difference in plasma clotting time among rats fed the dietary boiled eggs. The levels of plasma total cholesterol(TC) and low density plus very low density lipoprotein cholesterol(LDL, VLDL-C) were significantly(P<0.05) highest in group 95% boiled eggs diet compared to others. There were no differences in high density lipoprotein cholesterol(HDL-C) among rats fed the dietary boiled eggs. The levels of plasma TC, HDL-C, LDL$.$VLDL-C and the ratios of HDL-C/TC were not significant among the basal diet, 25% and 50% boiled eggs diets. These results suggest that the intakes of the dietary boiled eggs have the antithrombotic activity and plasma cholesterol lowering effect.

The purpose of this study was to investigate the differences in anthropometric, hematologic, and lipidologic data between normocholesterolemia and hypercholesterolemia and influencing factors in hypercholesterolemia in middle-aged men in Kwang-ju. 179 middle-aged men were involved. Anthropometric data(body weight, height, body circumferences and skinfold thickness) and hematologic data(blood pressure, fasting blood glucose, albumin and hemoglobin) were measured. Bleed lipid profile(total cholesterol, tr- iglyceride, phospholipid, HDI-cholesterol, LDL-cholesterol and VLDL-cholesterol) were analyzed. To determined using questionnaire. The subjects were classified as hypercholesterolemic based on The Guideline for Korean Hyperlipidemia. body mass index, systolic blood pressure, waist and hip circumference, and triceps, subcostal, abdomen, subscapular and suprailliac skinfold thicknesses of the hypercholesterolemic group were significantly higher than in the normocholesterolemic group. The concentrat- ion of cholesterol, triglyceride, phospholipod. HDL-cholesterol, LDL-cholesterol and VLDL -cholesterol of the hypercholesterolemic group were significantly higher than normocholesterolemic group. The concentration of cholesterol has a significantly positive correlation with body mass index, diastolic blood pressure, waist circumference, waist/thigh ratio and skinfold thickness(triceps, subcostal, abdomen, and supraillic skin- fold thickness). The general tendency of socioeconomec status, frequencyu of meat intake, smoking amounts and duration and duration and drinking frequencies and amount were higher in the hypercholesteolemic group but not significant. In conclusion, hypercholesterolemia in middle-aged men was closely correlated with upper body fat obesity and most of them had an accompanied high triglyceride level tendency.
