Background: The purpose of this study was to evaluate the effects of power walking and square dancing on middle-aged women with hypertension. Design: Randomized controlled Trial. Methods: 30 middle-aged women with hypertension were selected and divided into two groups. 15 cases in the control group received routine treatment, and 15 cases in the intervention group received community vigorous walking and square dancing intervention on the basis of routine treatment. The intervention time was 40-60minutes/day, 5days/week, total 16 weeks. total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), angiotensin II (Ang II), Leptin, blood pressure, and heart rate were measured. Results: Body weight, body mass index (BMI), TC, TG, LOW-density lipoprotein, angiotensin II, leptin, systolic blood pressure and heart rate were significantly reduced after power walking and square dancing (p<0.05). After the experiment, TC and TG in the experimental group were lower than those in the control group (p<0.05), while HDL was higher (p<0.05). Conclusion: The results of this study suggest that power walking exercises and square dances are significant effects on lipid mechanism and heart rate.

Lipid from Scenedesmus sp. was extracted, fractionated and purified by silicic acid column chromatography. Total lipid content of extract was $21.38{\pm}1.03$ wt%, and triacylglycerol, an index lipid for biodiesel production was detected. Ten species of $C_{16}{\sim}C_{22}$ with saturated and unsaturated fatty acid were identified showing the very adequate fatty acid profiles for biodiesel production with a good flow property at low temperature. The fractions of glycolipid, neutral and phospholipid were 52.64, 28.10 and 19.26% of total lipid, respectively. The triacylglycerol of 12.63% and chlorophyll a of 49.47% was fractioned using stepwise elution of n-hexane-diethyl ether (95:5, v/v) solvent. The high content of chlorophyll was considered as a potential source of value-added co-product.

Effects of dietary nutrient content on the biological index and serum chemistry of olive flounder Paralichthys olivaceus achieving compensatory growth were investigated. Six treatments were prepared in triplicate. Fish were hand-fed with the control (C) diet twice daily for 8 weeks (8W-C) or fish were starved for 2 weeks and then hand-fed with the C, high protein (HP), high carbohydrate (HC), high lipid (HL), or intermediate protein, carbohydrate and lipid (IPCL) diets for 6 weeks, referred to as 6W-C, 6W-HP, 6W-HC, 6W-HL, and 6W-IPCL, respectively. Weight gain of fish in the 8W-C, 6W-HP, and 6W-IPCL treatments was higher than that of fish in the 6W-C treatment. Condition factor (CF) of the fish in the 6W-HP, 6W-HC and 6W-IPCL treatments was higher than that of fish in the 8W-C and 6W-C treatments. The hepatosomatic index (HSI) of fish in the 6W-HC, 6W-HL and 6W-IPCL treatments was higher than that of the fish in the 8W-C, 6W-C and 6W-HP treatments. Serum chemistry except triiodothyronine ($T_3$) was not significantly different among the treatments. In conclusion, CF and HSI of the fish could be indices reflecting compensatory growth, whereas $T_3$ seemed to play a partial role in achieving compensatory growth.

Objectives: The objective of the present study was to investigate the lipid and the antioxidant regulatory potential of a multigrain diet in laboratory animals with reference to lipid profiles, tissue lipid peroxidation and antioxidant status. Methods: Two types of diets, with or without addition of cholesterol, were used in the study - a commercial diet and a formulated multigrain diet (with Sorghum vulgare, Avena sativa, Pennisetum typhoideum, Oryza sativa, Eleusine coracana and Zea mays grains). After a 10-week period of feeding the diets to albino rats the plasma, liver and fecal lipid profiles and the hepatic and renal antioxidant status of the animals that were fed the commercial and the formulated diets (with and without cholesterol addition) were assessed. Results: The commercial diet supplemented with cholesterol elevated the levels of plasma total lipids, total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and very low-density lipoprotein cholesterol (VLDL-C), as well as the atherogenic index (AI). The high-density lipoprotein cholesterol (HDL-C) content and the antioxidant profiles (total ascorbic acid, superoxide dismutase, catalase, glutathione peroxidase reduced glutathione) declined along with increases in lipid peroxidation. The formulated diet (with and without addition of cholesterol) was found to be more efficient than the commercial diet in controlling plasma, hepatic and fecal lipid profiles, as well as hepatic and renal lipid peroxidation and antioxidant status, than of the hypercholesteremic animals. Conclusion: The multigrain diet used in the present study is effective in countering the hyperlipidemia and oxidative stress caused by high cholesterol intake.

The purpose of this study was to investigate the relationship among plasma leptin, lipid profiles, insulin levels, and percentage of body fat of 72 schoolchildren from Obese Clinic Center in Seoul. The subjects divided into two groups: 39 obesity children [obesity index greater than $20\%$] who did not have a discernable medical cause of their obesity and 33 children with a obesity index less than $20\%$. The mean age, height, and obesity index of the subjects were 10.4 years, 144.0 cm, and $21.3\%$, respectively. The mean glucose and insulin levels of the obese children were 80.5 mg/dl and $13.3\;{\mu}IU/mL$ and those of the non obese children were 82.0 mg/dl and $4.2\;{\mu}IU/mL$, respectively. Obese children had significantly (p<0.05) higher level of total cholesterol, triglyceride, VLDL-cholesterol, LDL-cholesterol, and insulin concentration than non-obese children. However obese children had a lower level of HDL-cholesterol than non-obese children. Plasma leptin level were also positively correlated with BMI (p<0.000l), body fat (p<0.0001), tricep skinfold thickness (p<0.0001), mid arm circumference (p<0.0001), and waist hip ratio (p<0.0001). Plasma leptin showed a significantly positive correlation with insulin (p<0.0001), total cholesterol (p<0.0001), LDL-cholesterol (p<0.0001), and triglyceride (p<0.0001) levels, however, it was negatively correlated with HDL-cholesterol (p<0.0001) levels. In conclusion, the concentration of leptin in the blood is significantly correlated with the amount of body fat, BMI, plasma insulin, and plasma lipid profiles.

This study was performed to investigate the serum lipid and cholesterol lowering effects of kimchi powder or Lactobacillus plantarum when added to fermented sausage in rats. Male SD (Sprague-Dawley) rats were divided in three groups and administered with the following diets for 6 wk: non-fermented sausage added diets (CON), kimchi fermented sausage added diets (KIM), and Lactobacillus plantarum fermented sausage added diets (PLA). The CON has significantly (p<0.05) higher food intake, body weight gains, and final body weight than the other two groups. The body weight of KIM was significantly (p<0.05) lower than that of the other groups. The weights of organs (heart, lung, liver, kidney, spleen, perirenal adipose tissue, and epididymal adipose tissue) were not affected by any treatments. The mean value of serum triglycerides (TG) concentration in KIM and PLA groups was not significantly different compared with CON. Total cholesterol, low density lipoprotein and high density lipoprotein levels in serum of KIM were significantly (p<0.05) lower than those of CON. The serum free cholesterol level and atherogenic index (AI) in KIM and PLA were significantly (p<0.05) lower than those of CON. In conclusion, dietary supplementations with kimchi powder fermented sausages or L. plantarum fermented sausages were effective for lowering serum lipid, cholesterol levels and atherogenic index in rats.

The purpose of this study was to investigate the effects of the ethanol extract of Cynanchum wilfordii (ECW) on the blood lipid profile of hypercholesterolemic rats. Thirty 7-week-old male Sprague-Dawley rats were allowed free access to either a normal diet (AIN-93 diet), or 1% high-cholesterol diet with or without 0.5% or 1% ECW for 5 weeks. After sacrifice, the rat serum lipid profile was analyzed. The diets containing ECW decreased body weight gains compared to the normal diet. Serum HDL-cholesterol levels of ECW-fed groups were significantly increased in the hypercholesterolemic groups and normal groups (P<0.05). When 1% ECW was fed to the normal group, total cholesterol level was increased. Moreover, treatment of ECW in hypercholesterolemic groups yielded a dose-dependent and highly significant decrease in the atherogenic index as compared to the control. These results suggest that intake of Cynanchum wilfordii may help reduce the risks of hypercholesterolemia by increasing blood HDL-cholesterol and lowering the atherogenic index.

The present study was aimed to examine various factors related to serum total cholesterol, triglyceride, atherogenic index, lipoperoxides and vitamin E in 174 middle-aged men residing in Taegu. Body mass index was positively correlated with serum triglyceride, and waist-hip circumference ratio was positively correlated with serum total cholesterol, triglyceride, atherogenic index and vitamin E concentration. Total cholesterol, triglyceride and atherogenic index of the subjects who smoked more than 20 cigarettes per day were significantly higher than those with smoking less or non-smokers. drinking alcohol more than 5 times per week showed higher atherogenic index than drinking less frequently of non-drinking. Subjects doing exercise had higher HDL-cholesterol level than those with no exercise. The intakes of all nutrients were above 90% of RDA and the subjects with good food habit had lower of total cholesterol, triglyceride, atherogenic index and lipoperoxides. The study indicates that avoiding heavy smoking and drinking as well as obesity and keeping regular exercise, good food habit and diversity of foods will reduce risk of cardiovascular diseases in middle-aged men.
