This study was designed to observe the effects of Korean mistletoe(Viscum album L. var. coloratum Ohwi) hot-water extract administration on the improvement on the lipid components, apolipoprotein and blood pressure level in spontaneously hypertensive rats (SHR, Wistar strain, male) fed the experimental diets for 33 days. Concentrations of total cholesterol, triglyceride (TG), LDL-cholesterol, free cholesterol and atheroscieotic index in serum were significantly lower in the Korean mistletoe extract administration group [group KM(Korean mistletoe 10.0 g% hot-water extract)] than those in the control group. In the ratio of HDL-cholesterol concentration Korean mistletoe 10.0% hot-water extract administration group were higher percentage than in the control group. However, concentrations of total cholesterol and TG in liver and brain were significantly lower in the group KM than those in the control group. But the components of apolipoprotein (Apo) A-I and Apo A-II in serum were significantly higher in the KM group than in the control group. However, components of Apo C-II, Apo C-III, Apo E and ratio of Apo B to Apo A-I in serum were fairly reduced in the group KM than in the control group. The levels of systolic and diastolic blood pressure were significantly lower in KM cup than control group. From these results, Korean mistletoe hot-water extract administration were effective on the improvement of the lipid components, coronary heart disease and hypertension in spontaneously hypertensive rats. And particularly, Korean mistletoe extract administration were more effective as a therapeutic regimen for the control of blood pressure in hypertension.

This study was designed to investigate the effect of Ca supplementation of 1,000mg per day for 53 weeks on lipid, Na, and K metabolism and on blood pressure in postmenopausal women. The subjects were 12 healthy women aged from 60 to 70 years. They were divided into two groups : the placebo(control group) and the Ca supplemented(1,000 mg/day) group(Ca group). Metabolic studies were conducted twice in the 1st and the 53rd weeks. The results were as follows : Serum triglyceride, total cholesterol and LDL-choesterol levels tended to be decreased after the experiment. Serum VLDL-cholesterol lowering effect was observed with Ca supplementation(p<0.05), and also the significantly elevated HDL/(LDL+VLDL) ratio in Ca supplemented subjects whose average Na intake was as high as 4.9g per day. This phenomena was accompanied with increased Na retention and increased Na excretion in feces, but with decreased urinary Na in Ca supplemented group. However, considering much higher Na reteniton in the control group at the end of experiment(control va Ca ; 1272.3mg vs 732.9mg), Ca supplementation may have some beneficial effects on Na blance. Serum aldosterone level increased significantly in the Ca group after the exsperiment(p<0.05). With these normotensive subjects, there were no level increased significantly in the Ca group after the experiment(p<0.05). With these normotensive subjects, there were no pronounced effect of Ca supplementation on blood pressure, however, decrease in diastolic blood pressure were observed at the 14th week and end of the experiment(p<0.05). In summary, the Ca supplementation on postmenopausal Koran women appears to exert a desirables effect on blood lipid patterns related to the coronary heart diseases and to be beneficial in controlling diastolic blood pressure. Further studies with hypertensive or/and hyperlipidemic subjects are required to clarify the effect of Ca supplementation in Koreans.

In this study, we investigated the effect of seatangle drink and seatangle extract product on weight gain and serum and hepatic lipid composition in rats fed a hyperlipidemic diet. In the dietary hyperlipidemia induced rats, it was observed that serum triglyceride, phospholipid, total lipid, LDL-cholesterol level and atherosclerotic index were higher, while the HDL-cholesterol level was lower when compared to the normal group. Total hepatic lipid and cholesterol content of the dietary hyperlipidemia induced rats was conspicuously decreased by seatangle drink and seatangle extract product treatment. Especially, triglyceride content was decreased to 30% by seatangle drink treatment, and 45% by seatangle extract product treatment.

Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy caused by compression of the median nerve beneath the transverse carpal ligament. CTS can be correctly diagnosed by the patients' description of symptoms and electrophysiological tests that measure nerve conduction through the wrist. Many previous studies reported various risk factors of CTS, such as obesity, diabetes mellitus, thyroid disease and trauma. Obesity is associated with both hyperlipidemia and CTS. This study focused on the relationship between severity of CTS and serum lipid level. Methods: One hundred fourteen patients with CTS and 74 controls were divided into four groups according to the severity; normal, mild, moderate and severe. And then serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C) were measured in each group. Results: There was a positive correlation between TG and CTS severity (p<0.001). But TC, LDL-C and HDL-C were not correlated with CTS severity. Conclusions: These results suggest that high serum TG may act as an aggravating factor of CTS.

To evaluate the seasonal differences of nutrient intake and serum biochemical indices (total cholesterol, HDL-, LDL- cholesterol, TG, MDA : malondialdehyde, TAS : total antioxidant status, folate) in Korean college women with a mean age of 20.15y, this study was conducted twice: once in winter and a second time in summer. Anthropometric assessment was also measured in the two seasons. As a result body fat mass (p<0.05), body fat% (p<0.05), and abdominal fat% (p < 0.01) in the summer were significantly lower than those in winter. Intake of fat (p < 0.05), polyunsaturated fatty acid (p < 0.01), zinc (p < 0.05), and vitamin E (p < 0.05) were at significantly higher levels in the summer period compared with the winter period. In addition, nutrients with an intake level less than 75% RI of KDRIs were folate in winter and calcium, and folate in the summer. Total cholesterol (p < 0.05) and HDL-cholesterol in summer, according to lipid profiles, were significantly lower than those in winter. Although MDA, one of the products of lipid peroxidation, remained unchanged, TAS was significantly higher in summer than in winter. The level of folate in summer showed significantly lower than that in winter. The present study suggests that nutrient intake of college women women differs according to the seasons and anthropometric indices and serum biochemical indexes were associated with seasons. Thus nutritional education programs on the basis of season are needed for college women.

Purpose: Preterm infants on parenteral nutrition are at a relatively high risk for hypertriglyceridemia because they have immature lipoprotein lipase activity. The purpose of this study was to analyze the clinical factors affecting lipid metabolism in preterm infants receiving parenteral nutrition and to evaluate the influence of intravenous heparin on serum triglycerides to determine the adequate heparin dose to prevent hypertriglyceridemia in preterm infants. Methods: A single-center retrospective review was conducted among preterm infants receiving parenteral nutrition between January 2006 and February 2011. In 75 patients, 110 determinations were performed within 28 days postnatal age. Demographic and clinical data, including laboratory parameters, the dose and the duration of lipid administration, and the amount of intravenous heparin, were analyzed. Results: Serum triglycerides were higher in the small for gestational age (SGA) infants than in the appropriate for gestational age infants ($185.5{\pm}134.9$ mg/dL vs. $126.9{\pm}101.9$ mg/dL, p=0.019). Birth weight, gestational age, and body weight were negatively correlated with serum triglyceride level (r=-0.289, p=0.002; r=-0.208, p=0.029; r=-0.287, p=0.002, respectively). The serum triglyceride level was statistically lower in preterm infants receiving 1 U/mL of heparin than in those receiving 0.5 U/mL heparin or no heparin. Conclusion: Preterm infants receiving parenteral nutrition, particularly SGA and extremely low birth weight infants, tend to have hypertriglyceridemia. Thus, administration of 1 U/mL of heparin rather than 0.5 U/mL or none may be helpful to prevent hypertriglyceridemia in preterm infants.

The purpose of this study was to investigate the effects of Lycii fructus extract on the serum lipids in hyperlipemia rats. The rats were divided five groups including negative control, positive control and treated L. fructus extract at dose of 50, 100, 200 mg/kg. To induce the hyperlipemia, 4 groups of rats, not including the negative control group, were fed experimental diets consisting of cholesterol, lard, corn oil, and normal diet for experiment period. As a result, the L. fructus extract decreased total cholesterol(T. Cho), trigryceride(TG), low density lipoprotein cholesterol(LDL-C), and free fatty acid(FFA) significantly compared with positive control. However, no significant difference was found in high density lipoprotein(HDL-C) and phospholipid(PPL) level. Otherwise, in serum lipid level including, T-Cho, TG, LDL-C, FFA and PPL was decreased dose dependently by treatment of L. fructus extract. But HDL-C was increased by L. fructus extract too. Thereby having beneficial effect on hyperlipermia by influencing the serum lipid change, it is expected that Lycii fructus extract can suppress arteriosclerosis and obesity.

A study was carried out to investigate the effects of safflower seed powder on the improvement of lipid metabolism in high fat and high cholesterol fed rats. Male Sprague Dawley rats of 10 weeks old, weighing 325$\pm$5g, were divided into two groups; the control group(C group, high fat(10% lard) and high cholesterol(1% cholesterol)) and safflower seed group(S group, 10% safflower seed powder), they were fed experimental diets for 6 weeks. Food intake, body weight gains and organ weight had little differences between the groups. Concentration of lipoprotein in serum was remarkably lower in S group than in C group. Serum cholesterol levels were significantly lower in S group(72.94$\pm$4.08 mg/dl) than in C group(89.41$\pm$4.19mg/dl). The level of serum HDL cholesterol was higher in S group than in C group. The level of serum LDL C was significantly lower in S group than in C group. The ratio of HDL cholesterol to total cholesterol were higher in the S group than in the C group, too. The value of atherogenic index(AI) was determined to be low in S group. The content of liver triglyceride and cholesterol in the S group was lower than that of C group. ACAT activities which involves in cholesterol esterification in liver, was not significantly different between two groups.
