Purpose: The study investigated the effects of 9 weeks of group music rope-jumping training on health-related physical fitness and blood lipid in obese elementary school boys and girls. Method: Subjects were randomly assigned to either a training group (37 boys and 18 girls) or control group (36 boys and 19 girls). The training group exercised for 1 hour, 2 days per week during the 9-week supervised music rope-jumping training program. The control group was asked to maintain their normal daily physical activities. The effects of the interventions on physical fitness and blood lipids were analyzed by two-way repeated measures ANOVA (group ${\times}$ time). Results: There were significant group ${\times}$ time interaction effects on body weight (p<.023), %body fat (p=.09), body mass index (p=.018), and body fat mass (p=.019) in school girls. However, there was not an interaction effect on serum lipids in both genders. Conclusion: The 9-week music rope-jumping training program used was effective for improving body composition in obese elementary school girls.

The influence of three cooking methods (stewing, microwaving and Aluminium (Al) foil-baking) was evaluated on the content of intramuscular lipid and the composition of intramuscular fatty acids of Hyla rabbit. The percentage of intramuscular lipid in cooked-longissimus dorsi (LD) (dry weight %) were in the order mentioned below: microwaving > foil-baking > stewing. All treated samples showed decrease in the proportion of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA), whilst increase in the proportion of saturated (SFA) and n-6/n-3 value during processing. All of the cooked samples had the n-6/n-3 ratio within the recommended range (5-10). By the analysis of partial least squares regression (PLSR), the microwaving treatment was better to keep the stability of unsaturated fatty acids (UFA), whilst the long-time Al foil-baking did the most serious damage to UFA, especially the PUFA. In addition, the heating method showed greater influence on the samples than the processing time. The shorter processing time was better to retain the intramuscular PUFA of Hyla rabbit, especially the LC-PUFAs (C20-22). Considering all the factors, microwaving showed the superiority in reserving the composition of intramuscular fatty acids of Hyla rabbit.

To investigate the effects of krill and cadmium on lipid composition of plasma in cholesterol-fed rats, male Sprague-Dawley rats were raised for 4 weeks with 8 experimental diets. The cholesterol, ${\beta}-lipoprotein$, phospholipid and triglyceride concentration of plasma in rats fed krill diets containing below 5%9w/w) krill were not significant differences in comparison with those of control diet. The ingestion of cadmium caused a significant increase in free cholesterol 91.6-fold), triglyceride 91.6-fold), ${\beta}-lipoprotein$(1.4-fold) and total cholesterol (1.3-fold) level, and then HDL-cholesterol concentration of cadmium diet was 1.6-fold lower than that of control diet. The krill supplement of cadmium diet rather resulted in a increase in total cholesterol, free cholesterol, ${\beta}-lipoprotein$ and triglyceride concentration of plasma.

Purpose: This study was conducted to test the effect of the 12 weeks brisk walking exercise program on body composition, blood pressure, blood glucose and blood lipid for middle-aged woman with obesity. Method: The subject were 25 obese women in 40-64 yr old who were composed of over 30% body fat. For the analysis, descriptive statistics, paired t-test were used for statical analysis with SPSS 15.0. Result: The results were summarized as follows: first, the body weight, body mass index (BMI), % body fat of the obese woman were significantly decreased after implementing the 12 weeks brisk walking exercise program (p<.5). Second, the systolic blood pressure, diastolic blood pressure and blood glucose were significantly decreased after the 12 weeks brisk walking exercise program (p<.5). Third, the serum cholesterol was significantly decreased (p<.05) but serum triglyceride was not significantly decreased the after 12 weeks brisk walking exercise program. Conclusion: These results suggest that the brisk walking exercise program has an effect on decreasing body weight, BMI, percent body fat, blood pressure and serum cholesterol in middle-aged woman with obesity to reduce obesity and prevent chronic disease.

This research was performed to Investigate the effects of green tea on the lipid composition of serum and liver and the specific activities of antioxidative enzymes. Male Sprague Dawley rats were fed 10% fat diet with lard and fish oil. Powdered green tea was added to the lard and fish oil diet at the level of 0.1% and 1%. After 6 weeks of feeding, serum and liver were obtained from experimental rats. Then we measured the concentration of total cholesterol, HDL-cholesterol and triglyceride. From liver cytosolic fraction, we analized the specific activities of superoxide dismutase, glutathione peroxidase and glutathione S-transferase. The level of total cholesterol and triglyceride were decreased and the ratio of HDL-cholesterol to total cholesterol was increased by the fish oil in the serum. But in the liver, the level of total cholesterol was increased by the fish oil and green tea than the lard. The specific activities of glutathione S-transferase were more increased in the fish oil than the lard. There was not effect of the green tea of daily dose on the lipid composition of serum and liver and the specific activities of antioxidative enzymes in rats.

In diabetes, the abnormal increase of the membrane cholesterol/phospholipid ratio (C/PL) is consdered to be the main reason for the decreased membrane fluidity, which then results in impaired erythrocyte deformability and subsequent microcirculatory disturbances. In this study, we examined the effects of brazilin on lipid and phosphatidyl fatty acid composition of erythrocyte membranes in streptozotocin induced diabetic rats. Treatment of brazilin (10mg/kg or 100 mg/kg for 2 weeks, i.p) altered and cholesterol contents in diabetic erythrocyte membranes. The C/PL ratio of brazilin treated groups decreased compared with that of diabetic control group while no change was observed in normal erythrocytes. In streptozotocin induced diabetic rats, alterations in phosphatidyl fatty acid compositioin of erythrocyte membranes were observed and brazilin could reverse these alterations. Arachidonic acid level reumed to a normal level while linoleic acid level remained unchanged by the treatment of brazilin. The results suggest that brazilin might increase erythrocyte membrane fluidity which plays a key role inregulating erythrocyte deformability, thereby it could exert positive effects on microdiculatory disturbances.

the coricosteroid drug dexamethasone is an efficacious antiinflammatory drug, it is difficult to formulate in an injectable formulation due to its poor aqueous solubility. A lipid-based nanosphere formulation containing dexamethasone was designed for solubilization of the drug in aqueous solution and sustained release of the drug from the nanosphere. The lipid nanospheres, composed of phospholipid, cholesterol and cationic lipid, were prepared by self emulsification-solvent diffusion method followed by diafiltration. Physicochemical characteristics such as mean particle diameter, zeta potential and drug loading efficiency of the lipid nanospheres were investigated according to the variation of either the kind of lipid or the lipid composition. The lipid nanospheres had a mean diameter 80-120 nm and dexamethasone loading efficiency of greater than 80%. The drug loading efficiency increased with the increase of the length of aliphatic chain attached to the phospholipid. However, the drug loading efficiency was inversely proportional to the increase of cholesterol content in the lipid composition. The lipid nanosphere could not be prepared without the use of cationic lipid and the drug loading efficiency was proportional to the increase of cationic lipid content. The lipid nanospheres containing dexamethasone are a promising novel drug carrier for an injectable formulation of the poorly water-soluble drugs.

Lipid extraction preceding fatty acid methyl esters preparation for gas-liquid chromatography is time-consuming and cumbersome. We performed one-step extraction/methylation method with a mixture of methanol-heptane-benzene-DMP-H$_2$SO$_4$ without prior fat extraction. The simultaneous digestion and lipid transmethylation takes place at 8$0^{\circ}C$ in a single phase. After cooling till room temperature, two phases are formed. The upper one of the phases contains the fatty acid methyl esters ready for GLC. The fatty acid composition of major industrial crops obtained by the one step extraction/methylation method (method 1 and 2) was almost identical with the fatty acid composition of the pure fats extracted with hexane by the Soxtec instrument (method 3). Due to its simplicity, speed, and reduced organic solvent the one-step extraction/methylation method (method 1 and 2) should be useful to determine overall fatty acid composition, especially in situations where many samples have to be analyzed.
