Present communication deals with quantitative determination of total lipid, triglycerides, total free fatty acids, phospholipids and total cholesterol in the fat body tissue of the silkworm adapted to low and high temperatures. At the end of spinning process is characterized by a marked cellular reorganization of the different lipid fraction of the fat body irrespective of thermal acclimation. Accordingly, the per cent composition of triglycerides of the total lipid is increased accompanied by a corresponding decrease in free fatty acids, phospholipids and cholesterol.

Lipids of Job's tears (Yullmoo) were extracted by the mixture of chloroform: methanol (2:1, v/v) and from these lipids, triglycerides were separated by column chromatography (Sephadex G-25 column) and then confirmed by thin layer chromatography (TLC) and reconfirmed by gas chromatography (GC). The triglycerides were fractionated into 6 groups on the basis of their partition numbers (PN) by reverse phase high performance liquid chromatography (HPLC) on a column Shimpack CLC-ODS using tetrahydrofuran-acetonitril (25:75) mixture as a solvent. Each of these collected fractions gave one to two peaks in the GC chromatograms according to the acyl carbon number (CN) of the triglyceride and fatty acid composition of the triglycerides were also analyzed by GC. From the results, the major triglycerides of Job's tears lipids were estimated to be C18:1 C18:2 C18:2 (OLL, 38.2%), C16:0 C18:2 C18:3 (PLLn, 15.7%), C18:1 C18:1 C18:2 (OOL, 12.6%).

Effects of cooking and drying methods on the lipids content and neutral lipid component of shrimp, Metapenaeus joyneri, were investigated. Total lipid content of the fresh shrimp was 6.0%(dry basis), which was not changed significantly depending on the cooking and drying methods. Lipid of the fresh shrimp was composed of 36.8% of neutral lipids, 21.5% of glycolipids, and 41.7% of phospholipids. Freeze dried shrimp was substantially higher in neutral lipid contents but lower in glycolipid and phospholipid contents than hot air dried one. Main components of the neutral lipids were triglycerides, free sterols, free fatty acids and esterified sterols. Freeze dried shrimp contained higher triglycerides contents than hot air dried shrimp, whereas free fatty acids content in hot air dried shrimp was greater than that of freeze dried one due to the decomposition of triglycerides to free fatty acids during hot air drying. Major fatty acid composition of the total lipid were palmitoleic acid, eicosapentaenoic acid and docosahexaenoic acid, and that of neutral lipid were palmitic acid, palmitic acid, oleic acid, eicosapentaenoic acid and docosahexaenoic acid in fresh shrimp.

Medium chain triglycerides (MCTs) provide polka dot grouper Chromileptes altevelis with a more readily utilizable source of energy than long-chain fatty acids (LCFAs) and significantly elevate the plasma cholesterol level of chickens. As a possible alternative to feed antibiotics, this study investigated the effect of different phase levels of medium chain triglycerides on the growth performance, excreta microflora and blood profiles in broilers. A total of 450 ROSS 308 mixed-sex broilers with an average initial body weight of $49{\pm}0.79g$ (1 day of age) were used in this trial. They were randomly assigned to the following 3 treatments (15 birds / 10 replications): CON (Basal diet); MCT1 (Starter, Grower, Finisher: Basal diet + 0.1%, 0.075%, 0.05% of MCT) and MCT2 (Starter, Grower, Finisher: Basal diet + 0.1%, 0.1%, 0.1% of MCT). The results show that supplementing the diets with different phase levels of MCT did not have a significant impact on the body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR) during the overall experimental period. Additionally, there were no differences in the blood profiles and excreta microflora among the treatments. However, this study found that the BWG was increased by 2.3%, and the FCR was decreased by 0.6% in the broiler fed MCT1 treatment group during overall experiment phase. Therefore, the results suggest that MCTs could be used as an alternative to growth promoting feed additives. Moreover, further research should be done to evaluate the effect of the different levels of MCTs.

The present study was carried out to summarize the effect of caffeine in the lipid metabolic by meta-analysis. The association measure to test effect of caffeine was the Hedges's standardized mean difference (HG). In this particular fixed-effect model of Hedges's standardized mean difference, weight gain, heart weight, serum total lipid, serum triglycerides and liver triglycerides were significantly decreased (p < 0.05). Also, serum HDL cholesterol and serum LDL cholesterol were significantly increased. In this case of heterogeneous variable, random effect model was applied. In this model, weight gain, heart weight, serum total lipid, serum triglycerides, serum LDL cholesterol and liver triglycerides were significantly decreased in caffeine treated group. Also HDL-cholesterol was significantly increased in caffeine treated group.

The purposes of this study were to investigate the effects of drug use & the health-related habits(alcohol drinking, smoking and exercise) on the nutritional status of elderly. subjects were 362 free-living elderly aged over 65(male 131, female 231) in Chungbuk area. Interviews with questionaire on drug use, health-related habits, and nutrient intakes, anthropometric measurement and biochemical blood test were carried out from August to October in 1996. Energy intakes of the males who used drug were lower than those of males who did not use any drug, while energy intakes of the females who used drug were higher than those of females who did not. In biochemical indices, LDL-cholesterol level of the males who used drug was higher than that of males who did not have drug. serum triglycerides, VLDL-cholesterol and obesity degree(BMI & TS) of the females who used drug were higher than those of females who did not have drug. Alcohol drinking, smoking and exercise habits of the elderly who used drug had little effects on the nutrient intakes while those habits had considerable effects on biochemical indices and obesity degree. Among drug users, male drinkers showed higher triglycerides & HDL-cholesterol level, and female drinkers showed higher triglycerides and lower total cholesterol and LDL-cholesterol level, compared to non drinkers. Among female drug users, smokers showed lower body mass index(BMI) compared to non smokers. Males and females who had both drinking and smoking habits showed higher serum triglycerides and VLDL-cholesterol level. Especially females who had both drinking and smoking habits showed lower BMI & Tricep skinfold thickness compared to those who had netiher drinking nor smoking habits.

Emulsion body cleansing systems containing high levels of occlusives have recently been developed such as using insoluble crystalline hydroxy waxes, insoluble crystalline surfactant structures, encapsulated particles and smectite clay. In this study, moisturizing effect of various occlusives such as petrolatum and triglycerides was researched in emulsion body cleansing systems. The experiment shows that petrolatum has less moisturizing capacity in emulsion body cleansing systems than triglycerides. In "leave-on" products such as lotion and cream formulations, the moisturizing capacity of petrolatum is more than that of triglycerides, but in "wash-off" emulsion body cleanser of this research, different results appeared. Emulsion body cleansing systems contained high levels of anionic and amphoteric surfactants, therefore petrolatum has more solubility and less deposited amount into the skin during washing process than triglycerides.

Purpose: This study was conducted to investigate the prevalence and risk of gout in healthy workers. Methods: This cross-sectional analysis was conducted in 1,876 subjects (1,515 men and 361 women) enrolled in the Healthy Worker Cohort Study at Daegu, South Korea. Relationships between serum uric acid levels and independent risk factors were evaluated using multiple linear regression analysis after adjustment for covariates. Results: Among study participants, the prevalence of gout was 22.9% in men and 2.5% in women (based on a serum uric acid level >7.0 mg/dL for men and >6.0 mg/dL for women). Among men, increased ALT, GGT, total cholesterol, and triglycerides were associated with increased risk of gout (p<0.05) by multiple linear regression analysis; however, increased age and HDL-cholesterol/triglyceride ratio were associated with decreased risk of gout (p<0.05). In women, increased triglycerides were associated with increased risk of gout (p<0.05). Conclusion: Our findings suggest that increased triglycerides were significantly associated with the risk of gout in men and women. Moreover, a high HDL-cholesterol/triglyceride ratio in men may reduce the risk of gout.

Fibrates are a class of hypolipidemic agents whose effects are mediated by activation of a specific transcription factor called the peroxisome proliferator-activated receptor $\alpha\;(PPAR\alpha).\;PPAR\alpha$ regulates the pathways of lipid catabolism such as fatty acid oxidation and the triglyceride metabolism, resulting in the treatment of hyperlipidemia. The decreased levels of plasma triglycerides by fibrates are responsible for hypertrophy and hyperpalsia of adipose cells. To determine whether fenofibrate regulates adipogenesis in female C57BL/6J mice, we measured the effects of fenofibrate on not only body weight, adipose tissue mass and serum triglycerides, but also the histology of adipose tissue and the expression of adipocyte marker genes. Fenofibrate did not inhibit high fat diet-induced increases in body weight, adipose tissue mass and serum triglycerides. Furthermore, fenofibrate did not cause the changes in the size and number of adipocytes and the expression of adipocyte-specific genes such as leptin and $TNF\alpha$. Therefore, this study demonstrates that fenofibrate does not affect adipogenesis in female mice.

In this study, we studied the effect of onion on hyperlipidemia in terms of factors, such as body weight, liver weight, kidney weight, heart weight, blood glucose, total cholesterol, triglycerides, HDL-cholesterol, and LDL-cholesterol. The hyperlipidemia supplement was significantly effective on the liver weight, kidney weight, blood glucose, total cholesterol, triglycerides, and LDL-cholesterol with the fixed effect model. However, the liver weight, blood glucose, total cholesterol, and triglycerides were significantly decreased with the random effect model on the heterogeneous factors selected by Galbraith plot. The existence of publication bias was checked by using a funnel plot.
