This study is to find out the antioxidative effect and serum and liver lipid composition of wild grape juice in vivo. Forty 6-week-old white Sprague Dawley rats were divided into 4 groups such as normal lipid group, normal lipid group with wild grape juice, oxidized lipid (basic diet plus 10% of oxidative lipid) group and oxidized lipid group with wild grape juice, and 2ml juice was provided everyday. After 4 weeks of feeding with experimental diet each groups were examined for the antioxidant enzyme activity in blood and liver microsome and their serum and liver lipid composition. Glutanthione peroxidase activity in blood was significantly higher in oxidized lipid group with wild grape juice than in oxidized lipid group. Glutanthione peroxidase activity showed no difference depending on wild grape juice supplementation. Glutanthione peroxidase activity in liver was significantly higher in the groups with wild grape juice than in the groups supplemented only with oxidized lipid. Glutanthione reductase activity showed no difference depending on the supplementation of wild grape juice. Serum triglyceride level in the group supplemented with oxidized lipid diet and wild grape juice showed similar value to the normal lipid group and the normal lipid group with wild grape juiceoxidized fa6. Liver total lipid in the group supplemented with oxidized lipid and wild grape juice showed similar value to the normal lipid group and the group supplemented with normal lipid and wild grape juice. And it was lower than that of oxidative lipid group without juice. The liver triglyceride level in the group supplemented with normal lipid and wild grape juice was lower than that in the oxidative lipid group, but it was as low as in the group supplemented only with normal lipid.
This study was aimed at evaluating the nutritional status of Korean lactating women, who were attending peripheral community clinics in low-income areas, by anthropometric measurement, estimating dietary intakes and analyzing the contents of breast milk components, serum lipid content and fatty acid composition. Regarding anghropometric measurements, maternal circumferences decreased significantly at the trunk but not at the limbs. The skinfold thickness on all regions had the tendency to decrease during lactation. It was found that intakes of energy, protein, lipid and carbohydrates were desirable while calcium, zinc, copper and vitamin A were low and sodium was excessive. The energy $\%$of fat was 22.41$\%$of the total energy which is higher than the RDA for adults but it is proper for lactating women, but energy $\%$ from each fatty acid was usually low and an intake ratio of $\omega$6/$\omega$3 fatty acids was desirable. Accordingly, it is thought that dietary fat intake was balanced in quality. Concentrations of the nutrients in matured human milk showed the same range as that reported form different regions with the exception of calcium and magnesium which were relatively low. Serum lipid contents were decreased with the time postpartum and the average serum lipid content of lactating women were similar to the normal range of adults. Serum polyunsaturated fatty acids. especially $\omega$6 fatty acids have gradually increased with the time postpartum, but the composition were not greatly influenced by dietary intakes.
Increased incidence of myocardial infarction, arteriosclerosis and hypertension in oral contraceptive steroids users has been recognized as serious problem. Evidence have been accumulated that oral contraceptive steroids cause an increase in serum lipid levels, mainly triglyceride as well as an increase in serum cholesterol concentration in some women. Effect of oral contraceptives on serum lipids have been predominantly confirmed in Europian and American women. It should be emphasized that effects of contraceptives may he influenced by differences in nutrition, climate, socioeconomic status and race. The present study was, therefore, attempted to determine the effect of oral contraceptive steroids on serum lipid levels in Korean women and also to demonstrate whether the duration of pill treatment may affect serum lipid levels. Ten women, who had never taken contraceptive steroids, served as a control. One hundred women on combined oral contraceptive steroids were grouped according to the duration of pill use: duration of less than one year(14 women), 1-2 years(12 women), 2-5 years(29 women), 5-10 years(33 women) and more than 10 years(13 women). Serum levels of cholesterol, phosholipid and triglyceride were measured by enzymatic method, Fiske-SubbaRow method and Sugiura method respectively. The results obtained are as follows; 1) Oral contraceptive steroids increased serum cholesterol concentration by 4.8% as compared with cholesterol value of control group. But this increase was not statistically significant. 2) As compared with control value, concentration of serum phospholipid in pill-treated women decreased by 14.3%, which was statistically significant (p<0.05). 3) Concentration of serum triglyceride in pill-treated women increased by 10.6% over control value, but this increase was not statistically significant. 4) Duration of pill-treatment did not affect serum concentrations of cholesterol, phospholipid and triglyceride. From the results mentioned above, it may be concluded that combined oral contraceptive steroids, at least used for subjects involved in this study, decreased serum phospholipid significantly, thereby influencing serum lipid concentration.
Hypercholesterolemia has been regarded as a major risk factor of coronary heart disease(CHD). CHD is increasing in recent years among Koreans due to westernization of lifestyle and dietary behaviors. In the United States, implementation of the National Cholesterol Education Program(NCEP) had resulted 40% decline in mortality from CHD. This study was designed to evaluate the effect of medical nutrition therapy on serum lipid levels and discuss the effective nutrition education contents. Thirty outpatients(Male 40%, female 60%) with hypercholesterolemia were educated by medical nutrition therapy(MNT) protocol. At first visit and after three months of MNT, we assessed serum lipid profile, body weight and surveyed general characteristics, lifestyle and food habits through questionnaire. After 12 weeks of MNT, there were significant reductions in serum cholesterol and low-density lipoprotein cholesterol(LDL-C). Foods habits and lifestyle were changed to the desirable patterns. These results indicate that lipid profile is improved by changes of dietary behaviors and lifestyle. Especially in case of obesity, cholesterol lowering effect of MNT was more powerful. Consequently, MNT is effective on reduction of serum lipids by behavior change in hypercholesterolemic patients.

Purpose : We investigated the effects of horseback riding and horseback riding machine exercise on the serum lipid profile in elderly individuals. Methods : Our study included 30 healthy elderly individuals who were randomly assigned to 2 groups: the horseback riding and the horseback riding machine exercise group, with each group comprising 15 individuals. The riding exercise program was performed 25 times a week over 12 weeks. The repeated measures analysis of variance was used to determine changes in serum lipid profiles before and after exercise 6 and 12 weeks after exercise. Results : An intergroup comparison of blood tests showed that triglyceride, total cholesterol and low-density lipoprotein-C levels were decreased in both groups after 12 weeks of the riding exercise program. However, both groups showed an increase in high-density lipoprotein-C levels, although this difference was not statistically significant. Conclusion : Horseback riding and horseback riding machine exercise showed a positive effect on the serum lipid profile in elderly individuals.
This study was performed to elucidate the mechanism of dietary protein level on renal function through lipid and eicosanoids metabolism. Male rats of 337.8$\pm$5.7g body weight were undergone unilateral nephrectomy or sham-operation. The rats were divided into high protein(40% casein), normal protein(15% casein) and low protein(8% casein) diet groups and fed experimental diets ad libitum for 24 weeks. The results are summarized as follows. Serum total lipid, cholesterol and HDL-cholesterol of rats in 15% and 40% casein groups were higher than those of 8% casein group. But serum triglyceride was affected neither by uninephrectomy nor by dietary protein level. Serum thromboxane(TX) B2 and 6-keto prostaglandin F1$\alpha$ increased with increasing dietary protein level. Serum prostaglandin(PG) E2 was not affected by uninephrectomy nor by dietary protein level. Urinary PGE2 and TXB2 excretion tended to be lower in uninephrectomized groups. Renal tissue concentration of TXB2 was lower in uninephrectomized groups and in high protein group. These results suggest the possibility that the effects of dietary protein level on renal function could be due to changes in lipid and eicosanoids metabolism.
Many studies have shown that Letinus edodes has some effect on reducing blood pressure and lipid levels of animals with high pressure and hyperlipidemia. The cost of Letinus edodes varies depending on when it is harvested, and yet there has been no data collected on the bio-functional effects of Letinus edodes harvested at different times. This study was conducted to investigate the supplementary effects of Letinus edodes harvested at different times on blood pressure and blood lipid levels of hypertensive rats. Three kinds of experimental diets - control (CO), early harvested Lentinus deodes (EL), and late harvested Lentinus edodes (LL) - were supplied to spontaneously hypertensive rats (SHR) for eight weeks. The diet intake, body weight, organ weight, and serum lipid levels were subsequently measured. No significant difference was observed in diet intake and in the respective weights of the body, liver, and epididymal fat pad among experimental groups. The levels of systolic and disastolic blood pressure were significantly lower in the LE and LL groups than those in the CO group; and the concentration of serum total cholesterol was also lower in the LE and LL groups than in the CO group. These results confirm that Lentinus edodes reduces blood pressure levels and serum total cholesterol concentration in spontaneously hypertensive rats. But the effects of Lentinus edodes did not differ significantly based on whether the Lentinus edodes was harvested early or late.
Purpose: This study investigated the changes in body composition and serum lipid composition in obese women that were caused by a 12-week circuit exercise regime including both field and aquatic activities. Methods: Subjects comprised a total of 36 women who had a BMI of more than $25kg/m^2$. The simple obesity group (n=17) had no current or past record of medical complications, whereas the group with complications (n=19) also suffered from hypertension and/or diabetes. The circuit exercise program consisted of 12 weeks of 60%HRmax exercise sessions, five days a week. Results: While changes in every variable of body composition were significant, there was no statistically significant difference in the changes in serum lipid composition variables. With the exception of BMI, the correlation between the simple/complicated groups and exercising was statistically insignificant. Conclusion: These findings suggest that while a complex circuit weight exercise program that includes aquatic exercises significantly and positively alters obese patients' body composition it does not create statistically significant changes in their serum lipid composition. It can still be concluded, however, that increasing the duration of the exercise program would be effective to influence this. Moreover, personalized exercise programs that fit the needs of the individual participants seem necessary, given that the effect of exercise on body composition and serum lipid composition was greater in patients with simple obesity than in those with complications.

Effect of pine pollen and defatted pine pollen on lipid accumulation and metabolism in serum and liver were investigated with rats fed high fat-supplemented diets for 6 weeks. Concentrations of total lipid and total cholesterol in serum significantly decreased in the experimental groups (treated with pine pollen and defatted pine pollen) compared with the control group. Concentration of triglyceride in serum was remarkably lower than that of control group. This was similar to that of normal group. Concentration of glucose in serum was significantly lower in the experimental group. It was observed from photographs of hepatic tissue in rats that pine pollen inhibits the lipid accumulation induced by high fat diets.
This study was performed to find and compare the characteristics of dietary factors and obesity indices on serum lipid profiles using 407 healthy adult males that had physical examinations conducted at the general hospital located in Suwon. The subjects were divided 56.3% for the normal group, 16.7% for TG, 14.5% for TC and 12.5% for TC TG group, respectively. When comparing the blood lipid profiles to normal group, TC group was high in both total cholesterol and LDL-cholesterol, TG group was high in triglyceride and low in HDL-cholesterol, TC TG group was high in triglyceride, total cholesterol, LDL-cholesterol and low in HDL-cholesterol. In comparison of blood lipid profiles with normal group, among anthropometric factors, body weigh, BMI (Body Mass Index) and WHR (Waist Hip Ratio) showed significant differences. TC group was high in both total cholesterol and LDL-cholesterol, and TG group was high in triglyceride and low in HDL-cholesterol. TC TG group was high in triglyceride, total cholesterol and LDL-cholesterol, and was low in HDL-cholesterol. Body weigh of TG group was significantly higher than that of normal group (p<0.05). BMI and WHR of TG group and TC TG group were significantly higher than those of normal group (p<0.05). Total cholesterol was mainly related to the intake of animal lipids and alcoholic beverage. Serum triglyceride levels were closely related with lipid intake and high BMI in this group. In TC TG group, BMI and WHR were high. As well, serum LDL-cholesterol was high and HDL-cholesterol was low which indicates TC TG group had the most undesirable blood lipid profiles. Therefore, it may be necessary to manage BMI and WHR to prevent hyperlipidemia and obesity for adult males in Suwon.
