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.

This research was performed to investigate the effects of the supplementation of multi-extracts of mori folium (MF) and of exercise on blood lipid profiles and tissue differentiation in streptozotocin (STZ)-induced diabetic rats. The animal groups consisted of a normal-control group, a STZ-control group, three STZ-induced diabetic groups supplemented ad libitum with various amounts of MF extracts (MF-720, MF-360, and MF-180 groups), and a STZ-induced diabetic group supplemented with MF-360 combined with exercise; eight male Sprague-Dawley rats, 4 weeks old, were assigned to each experimental group and were raised in the laboratory for a 10 week experimental period. The MF supplementation group showed a significant reduction in levels of serum total cholesterol and triglyceride compared to the STZ-control group. HDL-cholesterol levels were significantly increased in the MF supplementation group compared to STZ-control group. The ratio of HDL-cholesterol to total cholesterol was significantly higher in MF supplementation group compared to the STZ-control group. The Atherogenic Index (AI) values in the MF supplementation groups were found to be significantly lower than in the STZ-control group. Serum AST and ALT levels were significantly reduced in the MF-supplementation groups compared to the STZ-control group. Total cholesterol level in the liver tissue was significantly decreased in the MF-360 group and in the MF-360 + exercise group compared to the STZ-control group. In immunohistochemical staining of the pancreatic islets of the MF-supplemented groups, a significantly higher number of insulin-immunoreactive cells were observed compared to the STZ-control group. In the MF supplementation groups, Bowman's capsules were clearly observed as hypertrophy of the glomeruli was not obvious. In the MF supplementation groups, a relative reduction in the hypertrophy of the basement membrane of the glomeruli and a significant reduction in the mesangium were observed compared to the STZ-control group. The results of this study suggest that supplementation of MF has beneficial effect in improving plasma lipid and tissue metabolism in streptozotocin-induced rats.

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.

This study was performed to study the effects of Gastrodiae rhizoma on lipid concentration of serum and liver in rats fed high fat diet. Male Sprague-Dawley rat were randomly assigned to 5 groups such as basal diet only(BDG), high fat diet(HFG) and high fat diet with 5% processed Gastrodiae rhizoma(GRL), high fat diet with 10% processed Gastrodiae rhizoma(GRM), high fat diet with 15% processed Gastrodiae rhizoma(GRH) supply each of the experimental diets for 6 weeks. Food intake was significantly decreased by both high fat intake and high fat with Gastrodiae rhizoma intake compared with basal diet intake but weight gain was not significantly different from each groups. Liver weights were significantly lowered by Gastrodiae rhizoma intake compared with high fat intake. In the serum, total cholesterol was not significantly different with each groups, but triglyceride level was significantly lowered by Gastrodiae rhizoma intake as compared with control. In the liver, lipid levels inceased with the Gastrodiae rhizoma intake, but total cholesterol and triglyceride levels were not significantly different with control. These results showed that dietary Gastrodiae rhizoma as supplementary food may decrease triglyceride in the serum.

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 effects of grape seeds extract and grape peels extract prepared from grape pomace on the activity of antioxidant enzymes, degree of lipid peroxidation in serum and liver tissue were investigated in rabbits fed on high cholesterol diet. New Zealand white rabbits were divided as follows ; 1) NOR (normal group); 2) CHOL (cholesterol group); 3) GSH (cholesterol + grape seed extract group); 4) GPE (cholesterol + grape peel extract); 5) GSP (cholesterol + grape seed powder); 6) GPP (cholesterol + grape peel powder); 7) GE (cholesterol + grape seed and peel extract); 8) GP (cholesterol + grape seed and peel powder). Eight groups of rabbits were studied for 8 weeks. At the end of the experimental period, rabbits were sacrificed and the liver tissue were removed. Then, GSH, GPx, GST, CAT and MDA in the liver were measured. In liver tissues, total glutathione contents (GSH), glutathione peroxidase (GPx) and catalase (CAT) activity, which was significantly higher by grape seed extract supplementation. The level of malondialdehyde (MDA) was lower in the serum of rabbits fed grape seed extract or grape peel powder plus cholesterol than in the serum of rabbits fed cholesterol alone. It is therefore likely that grape seed extract prepared from grape pomace functioned as antioxidants in vivo, negating the effects of the oxidative stress induced by 1% cholesterol diet. The grape seed extract was found effective in converting the oxidized glutathione into reduced glutathione, and in removing $H_2O_2$ that is created by oxidative stress. The grape peel powder was found to have small influence on reduced glutathione content, CAT and GPX activity, but it increased GST activity in liver tissues, resulting in promoting the combination of lipid peroxide and glutathione (GSH), and further, lowering the formation of lipid peroxide in the serum. Therefore, grape pomace (grape seed extract and grape peel powder) supplementation is considered to activate the antioxidant enzyme system and prevent damage with hypercholesterolemia.

To examine the effect of Saengshik on parameters related to hepatoprotective, anthropometric, blood pressure, serum lipid and blood related indices, nonalcoholic fatty liver subjects were treated with two meal portion of Saengshik in the replacement of meals for a period of three months. Weight, Body Mass Index (BMI) and systolic blood pressure were significantly decreased after the treatment. Chronically elevated serum aspartate aminotransferase (AST), gamma-Glutamyl transferase (r-GTP) and Alkaline Phosphatase (ALP) levels showed reduction to the near normal range. Serum total triglyceride level were reduced following the treatment. Whereas, there were no changes of serum total cholesterol with Saengshik consumption. Also, additional study was conducted to investigate the effect of Saengshik supplementation to high cholesterol and fat diet on lipid metabolism in rats. Male Spraque-Dawley rats were administrated hyperlipidemiainducing diet containing 1% cholesterol and 10% lard to induce hyperlipidemia for 4 weeks and were fed on diet containing Saengshik (30%, w/w) for 7 weeks. The feeding of diet containing 30% Shaengshik significantly decreased total cholesterol (TC) contents and total triglyceride. These results demonstrate Saengshik may be beneficial for fatty liver patients in improving their lipid metabolism.
