This study investigated the effects of chromium propionate on growth performance, serum traits and immune response in weaned pigs. Twenty-four 4 wk-old crossbred weanling pigs (initial body weight about 9.52${\pm}$0.48 kg) were randomly allotted into one of two groups, a control group (basal diet), chromium propionate group (diet supplemented with 200 ${\mu}g$ $kg^{-1}$ (ppb) of chromium propionate). This experiment was conducted over nine weeks. Escherichia coli lipopolysaccharide (LPS) 100 ${\mu}g$ $kg^{-1}$ BW was used as the stress-inducing agent in the middle (4 wks) and final (8 wks) periods. The experimental results indicated that chromium propionate had no effect on growth performance (p>0.05). Chromium propionate supplementation reduced the percentage of LDL+VLDL (low and very low-density lipoprotein) and increased HDL (high-density lipoprotein), but did not affect other serum traits. Pigs supplemented with chromium propionate had higher antibody titers specific for sheep red blood cells (SRBC) and serum total globulin relative to the control during the final period (p<0.05). A challenge with LPS increased white blood cells in the chromium propionate group in both experimental periods (p<0.05). The chromium propionate group exhibited higher IgG and $\gamma$-globulin than the control during the middle experimental period (p<0.05). Moreover, the PHA (phytohemagglutinin) challenge result in the chromium propionate group was better than the control group (p=0.056). Greater neutrophil activity was displayed than in the control (p<0.05). This suggests that chromium propionate supplementation benefited the weaned pigs in lipoprotein and immune response.

This study has been performed to investigate the changes in serum lipid and lipoprotein profiles of the national female soccer players during summer training season. Twenty five Korean national soccer players participated in the study. The mean age of the subjects was 23.3$\pm$2.5 years old. Their mean carrier as soccer player was 11.0 $\pm$2.6 years. Mean height was 164.4$\pm$5.7 cm and mean weight was 57.4$\pm$4.6 kg. Mean body fat percent was 23.9$\pm$3.0% and body mass index was 22.4$\pm$6.0. Mean serum triglyc eride concentration was normal (81.0$\pm$26.3 mg $dl^{-1}$), but total cholesterol (224.3$\pm$58.3 mg $dl^{-1}$) and LDL-cholesterol (162.2$\pm$59.0 mg $dl^{-1}$ were higher than normal range. Hematocrit, hemoglobin and total iron binding capacity were low, but in a normal range. Serum triglyceride concentration was negatively correlated with red blood cell counts (r=-0.448, p<0.05). Meanwhile, HDL-cholesterol was positively correlated with hematocrit percent (r=0.408, p<0.05). Therefore, better iron status was related with better serum lipid profiles of the subjects. Four weeks of iron supplementation had no effect on serum lipid and lipoprotein cholesterol of the subjects.

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.

To elucidate the effect of a 4 week dietary supplementation with pumpkin water extract on serum lipid and fasting glucose levels, 41 female collegians residing in the Gyeonggi area were recruited. The subjects were divided into three groups: placebo-control (PC, n=11), treatment A (TA, 100 ml/day, n=13), and treatment B (TB, 300 ml/day, n=17). Total serum cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglyceride (TG), and fasting glucose were analyzed. The average age, height, weight, and body mass index of the subjects were 21.3 years, 161.1 cm, 53.0 kg, and 20.4 $kg/m^2$, respectively. The average total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, and fasting glucose level (mg/dl) were 171.4${\pm}$26.1, 63.5${\pm}$11.4, 92.6${\pm}$22.9, 76.8${\pm}$32.0, and 89.1${\pm}$8.2, respectively. There were no significant differences among the three groups in any measured parameters, and between the pre- and post-study values of the all parameters. The results indicated that the 4 week pumpkin water extract supplementation (100 ml, 300 ml) did not influence the serum total cholesterol, HDL-cholesterol, LDL-cholesterol, TG and fasting glucose level in female collegians.

Object : This study was carried out to investigate the correlation between homocysteine and serum lipids which are known risk factors of stroke. Methods : The subjects were a total of 60 patients divided into a control group (n =30) and a sample group (n =30). The control group was normal homocysteine level without clinical symptoms, and the sample group was high homocysteine level with headache, dizziness, hypertension and so on. clinical symptoms, Each group was measured and compared for serum homocysteine, total cholesterol, triglyceride(TG), low density lipoprotein(LDL), and high density lipoprotein(HDL). Results : Total cholesterol, TG, and LDL were significantly increased and HDL was significantly decreased in the sample group. which was a high homocysteine level group compared with the control group, which was a normal homocysteine level group. Conclusion : In these results. it was suggested that increase of homocysteine leads to increase of serum total cholesterol, TG, LDL, but causes decrease of HDL. It seemed that risk of stroke is more at high homocysteine level than normal.

Twenty three healty women on self - selected diet were given 800IU of tocopherol daily for 4 weeks. The levels of tocopherol in plasma and red blood cells( RBC ) and total choles terol, TG, HDL- chol, HDL subfractions and lipoprotein pattern in serum were determined pre-and postregimen at 2 and 4 weeks. No significant change was noted in VLDL, LDL, HDL fraction and LDL/HDL ratio separated by electrophoresis, even though HDL fraction was decreased at 2 wk but slightly increased at 4 wk. There were also no significant changes in the relative amount of HDL-chol and VLDL-chol when cholesterol content of each lipoprotein fraction was assayed. A transient increase in LDL-chol was observed at 2 wk but returned to the pretreatment level. Plasma and RBC tocopherol levels were significantly ( p ^lt;0.05 ) increased and decreased respectively, at both 2 and 4 wk, and LDL-chol was positively correlated to plasma tocopherol level ( p<0.05 ) but not to RBC tocopherol. However HDL-chol fractionated by heparin-Mn was increased at 2 and 4 wk by a significant increase in $HDL_{2}$-chol but no change in $HDL_{3}$-chol, which resulted in a significant reduction of $HDL_{3}$/HDL ratio and increase of $HDL_{2}/HDL$ and $HDL_{2}/HDL_{3}$ ratios. HDL- chol was negatively correlated to the levels of LDL-chol ( p<0.05), VLDL-chol (p<0.01), and T-chol/HDL ratio ( p<0.01 ). Serum TG was significantly decreased ( p <0.05 ) but total cholesterol was decreased only at 4 weeks.

In order to investigate the effect of ginseng saponins on the activity of lipoprotein lipase, it was attempted to conform the enzymatic hydrolysis of chylomicron with post-heparin induced plasma lipoprotein lipase of normal rabbit in vitro. And the activity of lipoprotein llipase was determined by the quantitative determination of liberated free fatty acids on the hydrolysis of chylomicron. As the result, it was observed that the ginseng saponins accelerated the hydrolysis of chylomicron by post-heparin plasma in vitro. And the optimum concentration of ginseng saponins for the activity of the lipoprotein lipase in the 2% bovine serum albumin was $10^{-4}%$. But ginseng saponins on the hydrolysis of chylomicron was influenced by the presence and the absence of albumin. And the optimum concentration of albumin and Na-cholate on the activity of lipoprotein lipase was each of the $10^{-6}%$ albumin and 5mM Na-cholate. From these results, it seems that ginseng saponins might stimulate the intravascular hydrolysis of chylomicron.

Objectives: This study compared serum lipid concentration according to drinking habits. Methods: We analyzed data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII). The study included 8,525 adults (3,651 males and 4,874 females), aged 30 - 59 years. Results: There were differences in age, gender, education level, smoking status, physical activity, and waist circumference between drinkers and abstainers. The serum low-density lipoprotein-cholesterol (LDL-C) level of the drinkers was lower than those of the abstainers (P < 0.05). The serum triglyceride (TG) and high-density lipoprotein-cholesterol (HDL-C) concentrations were highest in the group that consumed alcohol 'more than twice a week' relative to the other groups (P < 0.001). The LDL-C and atherogenic index (AI) levels were lowest in the 'more than twice a week' drinking group compared to the other groups (P < 0.001). The serum TG and HDL-C concentrations were the highest in the '7 glasses/time' group (P < 0.001). The serum LDL-C concentration was the lowest in the '7 glasses/time' group (P < 0.001). Notably, the higher the frequency of binge drinking (7 glasses or more), the higher the concentration of TG (P < 0.001). The serum HDL-C concentration was significantly higher in the 'no binge' and 'more than once a week' groups compared to the other groups (P < 0.001). The serum LDL-C concentration and AI score were the lowest in the 'more than once a week' group (P < 0.001). Conclusions: As the quantity and frequency of drinking increased, the serum TC concentration increased. Moreover, an increase in the serum HDL-C concentration led to a decrease in AI. The factors exacerbating cardiovascular disease increased simultaneously due to drinking. Our results suggest that for individuals with hypertriglyceridemia and patients with low HDL-cholesterolemia, separate guidelines based on the quantity and frequency of alcohol consumption are warranted.

This study was planned to investigate the role of Berberis lycium in reducing serum cholesterol in broilers. Six experimental rations designated as A, B, C, D, E and F having 0, 0.5, 1.0, 1.5, 2.0 and 2.5% Berberis lycium were fed to 240 broiler chicks, randomly distributed into 24 replicates, so as to have 4 replicates per group and 10 chicks per replicate. The experiment lasted for 35 days. Average serum total cholesterol, triglyceride, high density lipoprotein (HDL) and low density lipoprotein (LDL) were used as criteria of response. Average total serum cholesterol per chick was 129.33, 120.50, 116.50, 113.00, 101.67 and 114.00 mg/dl for group A, B, C, D, E and F respectively. Total serum cholesterol showed decreasing trend with the increasing level of Berberis lycium unto 2% (p<0.05). Mean serum triglyceride level per chick was 60.00, 58.17, 58.00, 55.33, 50.17 and 48.50 mg/dl for group A, B, C, D, E and F respectively. Mean serum triglyceride showed decreasing trend with the increasing level of Berberis lycium (p<0.05). Serum triglyceride was significantly lower in group F than other groups. Mean HDL per chick for the six experimental groups A, B, C, D, E and F was 52.08, 53.42, 60.42, 62.25, 62.92 and 54.50 mg/dl respectively. HDL showed increasing trend with the increase in the level of Berberis lycium unto 2%. The average serum LDL per chick was 65.25, 55.45, 44.48, 39.68, 28.72 and 49.80 mg/dl for group A, B, C, D, E and F respectively. LDL also showed decreasing trend with the increase in the level of Berberis lycium unto 2% (p<0.05). It was concluded that Berberis lycium added to feed at the rate of 2.0% can be used in broiler feed for reducing serum total cholesterol, triglyceride and LDL and increasing HDL.

Purpose: The prevalence of obesity has significantly increased among children and adolescents worldwide and is becoming an important health care problem in parallel with the increased prevalence of obesity pediatric non-alcoholic fatty liver disease. Betatrophin is a newly define hormone that is commonly secreted by liver and plays role in glucose tolerance. This study aimed to investigate the relationship between serum betatrophin levels and non-alcoholic fatty liver disease in obese children. Methods: The study included 40 obese children with a body mass index (BMI) above 95th centile, and 35 non-obese subjects with a BMI 3-85th centile, whose age and gender were similar to those of the patient group. For the evaluation of metabolic parameters fasting serum glucose, insulin, alanine aminotransferase, aspartate aminotransferase, lipid profile and serum betatrophin levels were measured. Total cholesterol: high-density lipoprotein cholesterol and low-density lipoprotein cholesterol: high-density lipoprotein cholesterol ratios were calculated as "atherogenic indices." Results: Serum betatrophin levels of the obese subjects were similar to that of non-obese subjects (p=0.90). Betatrophin levels were not correlated with the metabolic parameters. Conclusion: In the present study, levels of betatrophin are not different between obese and insulin resistant children and non-obese subjects, and they are not correlated with atherogenic indices. To elucidate the exact role of betatrophin in obesity, further studies are required to identify the betatrophin receptor and/or other possible cofactors.
