The purpose of this study was to find the effect of dietary polyunsaturated fat on of vitamin levels E, total cholesterol and HDL-cholesterol in serum of Spraque-Dawley male rats. Experimental rats were fed for 4 weeks with corn oil, perilla oil, lard at a level of 10% and 20% respectively. The results obtained are as follows; 1. Body weight gains were similar to all groups and food intake was significantly lower in all experimental diet groups than control diet group, especially 20% corn oil diet group was the lowest among the experimental diet groups. 2. Vitamin E levels in serum were significantly lower in 20% corn oil and 10%, 20% perilla oil diets groups than control diet group. 3. Serum total cholesterol levels were significantly higher in 20% perilla oil diet group which was significantly lower in vitamin E level than control diet group, and serum total cholesterol levels of 10%, 20% lard diets groups were significantly higher than control diet group. 4. Serum HDL-cholesterol levels were significantly lower in 20% perilla oil diet group which was significantly lower in vitamin E level than control diet group, and serum HDL-cholesterol levels of 10%, 20% lard diets groups also were significantly lower than control diet group.

The study examines the effects of the Cnidium officinale Makino water extract on hyperlipidemia. For this, three levels (low, moderate, and high) of the Cnidium officinale Makino water extract were supplemented to six-week-old male sprague Dawley rats for five weeks. According to the results, serum total lipid, triglyceride, total cholesterol, and LDL cholesterol levels showed significant decreases (p<0.05) in the group with the Cnidium officinale Makino water extract. The serum total lipid level decreased by 8~22%; the triglyceride level, by 13~25%; the total cholesterol level, by 6~23%; and the LDL cholesterol level, by 14~25%. Total cholesterol and triglyceride levels in the liver were significantly lower in the group with the Cnidium officinale Makino water extract than in the control group (p<0.05), and fecal total cholesterol and triglyceride levels were significantly higher in the group with the Cnidium officinalle Makino water extract. These results suggest that the Cnidium officinale Makino water extract in the hypercholesterol diet may reduce hyperlipidemia, a major cause of cardiovascular disease, by reducing serum cholesterol and triglyceride level in the liver through the facilitation of their excretion by feces.

This study was designed to investigate effects of lobster shrimp chitosan on serum and liver lipid levels in rats fed high fat and cholesterol diets. Male Sprague-Dawley rats of 4-weeks old, weighing 70$\pm$5g, were fed experimental diets for 3 weeks: basal diet+5% cellulose(group 1), high lipid diet+5% cellulose(group 2, control group), high lipid diet+5% balloon flower root(group 3), high lipid diet+5% cellulose(group 4, high lipid diet+5% lobster shrimp chitosan(group 5). Concentrations of total cholesterol, HDL-cholesterol, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride, phospholipid in serum and liver were determined. The results obtained were as followes: Serum total cholesterol concentration were significantly reduced in all supplemented group compared with control. HDL-cholesterol concentrations were higher in groups 1, 4, and 5 and the ratios of HDL-cholesterol to total cholesterol concentration were higher in groups 1, 4, while the atherogenic-indices were lower in groups 1, and 4 than control. Concentrations of LDL, LDL-cholesterol and free cholesterol, cholesteryl ester were significantly lower in all supplemented groups than the control group. Concentrations of phospholipid and triglyceride were lower in groups 3, 4, 5, while activities of GPT and GOT were significantly lower in groups 4, 5 than the other group. Concentrations of calcium, magnesium and phosphorous were high in all treatment groups compared to the control group. Liver contents of total cholesterol, free cholesterol and cholesteryl ester were lower in the groups 1, 3, 4, and 5 than in the control group, especially lower in groups 1, and 5. Liver triglyceride and phospholipid concentrations were significantly lower in the groups 1, and 5 than in the other groups. The results from the data suggested that the experimental diet containing 5% lobster shrimp chitosan was effective to reduce the serum and liver lipids.

As fat consumption has increased in Korea , serum cholesterol concentrations have risen and the prevalence of atherosclerosis increased. The aim of the present study was to investigate the association among apolipoprotein E (Apo E) phenotypes, dietary fat consumption, plasma lipoprotein levels and fatty acid compositions of red blood cells in young healthy women. Seventy-one percent of participants had Apo E3/3, 14.9 percent had ApoE3/2 , 11.8% had Apo E4/3 and 1.2% had Apo E4.2. The subjects daily consumed approximately 1760kcal containing 29 energy % of fat. The ratio of polyunsaturated fat to saturated fat in a diet was 0. 73 . There were no significant differences of nutrient intakes according to Apo E phenotypes. Total cholesterol concentrations of subjects averaged approximately 160mg/dl , but 12 percent of them had over 200mg/dl, which is higher than the range recommended by the National Cholesterol Deucation Program. Notably, most subjects with 210mg/dl had Apo E4 isoforms. Subjects with Apo E4 isoforms had significantly higher total and LDL-cholesterol concentrations than those with Apo E3/2. Also subjects carrying Apo E4 isoforms tended to accumulated more fat in the body. Their BMI , WHR and arm fat area appeared to be how can arm fat area be greater no you mean grater, please check work vsage than subjects with Apo E3 isoforms, but not significantly. Fat intakes slightly influenced serum cholesterol levels. Myristic aicd intakes were positively correlated to serum total and LDL-choelsterol levels. Polyunsaturated fatty acid intakes were negatively correlated to serum total choelsterollevels. The results of 소냐 study suggest that , people with Apo E4 isoforms need to prevent the raising of serum total and LDL -cholesterol concentrations by reducing calorie and fat intakes and by maintaining a normal weight.

The cholesterol and fatty acid levels in serum and liver were compared in 4-week-old Sprague-Dawley male fed by addition of polymannuronate (M, 5.0％), polyguluronate (G, 5.0％), and polymannuronate and polyguluronate (MG, 2.5％ to each) with by addition of cholesterol (1.0％). Feed efficiency by the addition of M, MG, and G was lower than cholesterol fed group (p＜0.01). The liver weights were less in M, MG, and G fed groups than in cholesterol fed group (p＜0.01). Triglyceride levels in serum and liver were 58.2∼77.4％ and 51.5∼65.5％ lower in M, G and MG fed groups than cholesterol fed group, respectively. Total-, LDL-, and free-cholesterol levels in serum and liver in M, MG, and G fed group were significantly lower than cholesterol fed group. The cholesterol levels were the most reduced in M fed group. However, HDL- cholesterol level in serum was increased in M, MG, and G fed group (p＜0.01). The of polyene levels were 47％ higher in serum and 76％ in liver in M fed group than in cholesterol fed group. The activities of GOT and GPT were lower in M, MG, and G fed group than in cholesterol fed group (p＜0.01). Above the results demonstrate that supplementation of low molecular polymannuronate in diets improve physiologically lipid composition in serum and liver.

This study was carried out to investigate the effects of rice germ oil supplement on the lipid metabolism of insulin-dependent diabetic mice. Streptozotocin-induced diabetic mice were fed three kinds of experimental diets with 20% lipid, composed of 20% lard (L) : 10% lard and 10% rice germ oil (LRGO) ; and 20% rice germ oil (RBO), respectively, for 7 weeks. Diet intake, body weight, organ weight and lipid levels of serum, liver and feces were measured. There was no significant difference in diet intake, body weight and organ weight among the experimental groups. But the concentrations of serum triglyceride in the LRGO and RGO groups, and of serum total cholesterol in the RGO group, were significantly lower than those of the L group fed the 20% lard diet. The levels of hepatic total lipid of the RGO group, and of hepatic total cholesterol of the LRGO and RGO groups were significantly lower than those of the L group. The contents of total lipid and total cholesterol excreted in the feces of the LRGO and RGO groups were higher than those of the L group. These results suggest that rice germ oil can reduce the levels of total cholesterol concentrations in the serum or livers of insulin-dependent diabetic mice, and that the hypolipidemic effect of rice germ oil may be due to increasing fecal lipid excretion and decreasing lipid absorptivity.

There is growing evidence that soy isoflavones play beneficial role in the prevention of cardiovascular disease. However, current data are not sufficient to determine the effective dose of isoflavone on improving plasma lipid profiles and total antioxidant capacity in Korean menopausal women. In the present study, 24 perimenopausal and 23 postmenopausal women were divided into 3 groups and were given soy isoflavone supplements of 100, 150, 200mg/day for 12weeks. Blood samples were taken before and after 6, 12weeks of soy isoflavone supplementation for analysis of total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride and total antioxidant status(TAS). In the perimenopausal women, serum total cholesterol level decreased significantly in all three groups after 12weeks of isoflavone supplementation(p< 0.05). However, serum LDL cholesterol level significantly lowered only in 150 and 200mg groups, and serum triglyceride level decreased significantly in 200mg group(p<0.05). In the postmenopausal women, the 150mg isoflavone supplementation group demonstrated significant effects on lowering serum total cholesterol, LDL cholesterol levels and raising HDL cholesterol level after 12weeks of isoflavone supplementation(p<0.05). Two hundred mg isoflavone supplementation group had a significantly higher TAS than other groups in both perimenopausal and postmenopausal women. (Korean J Nutrition 34(3) : 322∼329, 2001)

In other to study relationship of anxiety and serum cholesterol in general population, we performed the interview survey and screening test for the Ju-am cohort and residents in controlling area at 1995. Among them, 622 people are selected for this analysis. The results were summarized as follows. 1. Anxiety and total serum cholesterol related each other in the group of anxiety. Correlation coefficient was 0.39(p<0.01). 2. According to the result of multiple regression that the total serum cholesterol regarded as the dependent variable, anxiety and total serum cholesterol were related each other positively in the group of anxiety(p<0.05). 3. As the symptoms of anxiety was dichotomized affective and somatic symptom. There was no relationship of 2 symptoms and total serum cholesterol in all subjects, but there was more relationship on the affective symptom than on the somatic symptom in the group of anxiety(p<0.05). The above results show that anxiety and total serum cholesterol related each other significantly in the anxiety group. And the relationship of psychological factors and serum cholesterol could be applied significantly in general population as well as in the special group.

This study investigated the effects of dietary soy protein and Ca on the lipid profiles of rats fed fat-enriched diets. Rats were divided into two groups and fed either a casein-low Ca (Exp I) or ISP-high Ca diet (Exp II) for a control period of 4 weeks. The two groups of rats were again subdivided into 4 groups and fed one of 4 experimental diets for another 4 weeks. The experimental diets consisted of 18% beef tallow and 1 % cholesterol, in which either 20 % casein or ISP with one of two levels of Ca, high (1 %) or low (0.1 %). The concentrations of total lipid, cholesterol and triglyceride in serum, liver and feces were determined. At the end of the control period, the serum total lipid and cholesterol concentrations were low in the rats fed ISP-high Ca diet (67~76% and 83~86%). During the next 4 week period, these concentrations remained significantly lower in rats fed the diets containing ISP and high Ca compared with those on casein and low Ca diets (p ＜ 0.05). Total lipid and cholesterol concentrations in feces were significantly higher in the ISP-high Ca dietary group at 4 weeks, and high in both high Ca groups at 8 weeks. This study demonstrates that both soy protein and Ca reduce serum and liver cholesterol, triglyceride, and total lipid in rats fed fat-enriched diet, and that they have an additive effect when combined.
