A highly obese female patient (body mass index=$30.8kg/m^2$) participated in a 10-day Gamrosu modified fasting therapy with soluble dietary fiber supplementation to enhance lipid metabolism. Gamrosu is a modified fasting therapy beverage which is made from medical herbs and carbohydrates (431 kcal/d). Before and after fasting, we evaluated the efficacy of therapy by measuring the changes of body composition and blood chemistry. After the modified fasting therapy, -6.1% of body weight and -5.6% of body fat mass were decreased. With regard to blood chemistry, all the plasma lipid levels were lowered. -37.4% of total cholesterol, -39.7% of low density lipoprotein cholesterol, -39.0% of triglyceride and -27% of high density lipoprotein (HDL) cholesterol were reduced. Further studies are needed to alleviate the reduction of HDL-cholesterol to apply the Gamrosu modified fasting to hyperlipidemia.

BACKGROUND/OBJECTIVES: Evidence indicates that berry anthocyanins are anti-atherogenic, antioxidant, and anti-inflammatory. However, berries differ vastly in their anthocyanin composition and thus potentially in their biological and metabolic effects. The present study compared hypolipidemic, antioxidant, and anti-inflammatory properties of blueberry (BB), blackberry (BK), and blackcurrant (BC) in a diet-induced obesity (DIO) mouse model. MATERIALS/METHODS: Male C57BL/6J mice were fed a high fat (HF; 35% fat, w/w) control diet or a HF diet supplemented with freeze-dried 5% BB, 6.3% BK or 5.7% BC for 12 weeks (10 mice/group) to achieve the same total anthocyanin content in each diet. Plasma lipids, antioxidant status and pro-inflammatory cytokines were measured. The expression of genes involved in antioxidant defense, inflammation, and lipid metabolism was determined in the liver, epididymal adipose tissue, proximal intestine, and skeletal muscle. Histological analysis was performed to identify crown-like structure (CLS) in epididymal fat pads to determine macrophage infiltration. RESULTS: No differences were noted between the control and any berry-fed groups in plasma levels of liver enzymes, insulin, glucose, ferric reducing antioxidant power, superoxide dismutase, and tumor necrosis factor ${\alpha}$. However, BK significantly lowered plasma triglyceride compared with the HF control and other berries, whereas BC significantly reduced F4/80 mRNA and the number of CLS in the epididymal fat pad, indicative of less macrophage infiltration. CONCLUSIONS: The present study provides evidence that BB, BK and BC with varying anthocyanin composition differentially affect plasma lipids and adipose macrophage infiltration in DIO mice, but with no differences in their antioxidant capacity and anti-inflammatory potential.

The effect of perilla oil added in diet on the biochemical properties of cultured sweet smelt, Plecoglossus altivelis, was investigated. The cultured fish were fed two different diets for 8 weeks; a control diet was a commercial diet, which was low in the content of docosa­hexaenoic acid (DHA, 22: 6n-3) and eicosapentaenoic acid (EPA, 20: 5n-3) less than approximately $2\%$ (CO group) and an experimental diet (PO group) was added perilla oil as a lipid source in the diet of the CO group. The PO group was superior in growth rate and feed efficiency compared with CO group. This trend showed markedly in female of both groups. The fatty acid composition in the muscle of PO group was closely related with those of the diet, while those of CO group were not. For plasma components, total cholesterol (CHOU of PO group was higher than that of CO group. Thiobarbituric acid-reactive substances (TBARS), hydroxyl (OH) radical levels and superoxide dismutase (SOD) activity of plasma were higher in PO group than CO group. The intensity of watermelon-like or cucumber-like aroma was much stronger in PO group with higher level of TBARS and OH radical in plasma compared CO group. Survival rate was also high in PO group with high levels of phagocytic rate, CHOL and SOD activity. These results suggest that perilla oil might be usefulness as a lipid source of the cultured sweet smelt diet, in which result in high quality of the cultured fish.

Porosomes are supramolecular, lipoprotein structures at the cell plasma membrane, where membrane-bound secretory vesicles transiently dock and fuse to release inravesicular contents to the outside during cell secretion. The mouth of the porosome opening to the outside, range in size from 150 nm in diameter in acinar cells of the exocrine pancreas, to 12 nm in neurons, which dilates during cell secretion, returning to its resting size following completion of the process. In the past decade, the composition of the porosome, its structure and dynamics at nm resolution and in real time, and its functional reconstitution into artificial lipid membrane, have all been elucidated. In this mini review, the discovery of the porosome, its structure, function, isolation, chemistry, and reconstitution into lipid membrane, the molecular mechanism of secretory vesicle swelling and fusion at the base of porosomes, and how this new information provides a paradigm shift in our understanding of cell secretion, is discussed.

This study was conducted to investigate the effects of dietary lipid source and level on growth performance, blood parameters, fatty acid composition and flesh quality of sub-adult olive flounder Paralichthys olivaceus. Eight experimental diets were formulated to contain 5% squid liver oil (SLO), 5% linseed oil (LO), 5% soybean oil (SO), a mixture of 1% squid liver oil, 2% linseed oil and 2% soybean oil (MIX), no lipid supplementation with high protein level (LL-HP), 10% squid liver oil (HL-SLO), a mixture of 1% squid liver oil, 4.5% linseed oil and 4.5% soybean oil (HL-VO), and 1% squid liver oil with high starch level (LL-HC), respectively. Two replicate groups of fish (average initial weight of 296 g) were fed the diets for 17 wks. After 5 wks, 11 wks and the end of the feeding trial, five fish from each tank were randomly sampled for analysis of body composition. At the end of the feeding trial, final mean weight of fish fed the LL-HP diet was significantly (p<0.05) higher than that of fish fed the HL-VO diet, but did not differ significantly from those of fish fed the SLO, LO, SO, MIX, HL-SLO and LL-HC diets. Fish fed the LL-HP diet showed significantly higher feed efficiency than fish fed the LO, HL-SLO and HL-VO diets. Feed efficiency of fish fed the LO, SO and MIX diets were similar to those of fish fed the SLO and HL-SLO diets. Fish fed the HL-SLO diet showed significantly higher total cholesterol content in plasma compared with other diets. Fatty acid composition of tissues was reflected by dietary fatty acid composition. The highest linoleic (LA) and linolenic acid (LNA) contents in the dorsal muscle were observed in fish fed the SO and LO diets, respectively, regardless of feeding period. The highest eicosapentaenoic acid (EPA) content in the dorsal muscle was observed in fish fed the LL-HP and LL-HC diets after 11 and 17 weeks of feeding, respectively. Fish fed the SLO and HL-SLO diets showed higher docosahexaenoic acid (DHA) content than that of other treatments after 11 and 17 weeks of feeding, respectively. Dietary inclusion of vegetable oils reduced n-3 HUFA contents in the dorsal muscle and liver of fish. The n-3 HUFA contents in tissues of fish fed the SLO and HL-SLO diets were higher than those of fish fed other diets, except for the LL-HP and LL-HC diets. Hardness, gel strength, chewiness and cohesiveness values of dorsal muscle in fish were significantly affected by dietary lipid source. The results of this study indicate that fish oil in fish meal based diets for sub-adult olive flounder could be replaced by soybean oil and linseed oil without negative effects on growth and feed utilization.

This experiment aims to investigate the impact of probiotic feed on growth performance, carcass traits, plasma lipid biochemical parameters, intramuscular fat and triglyceride content, fatty acid composition, mRNA expression levels of genes related to lipid metabolism, and the activity of the enzyme in Sunit sheep. In this experiment, 12 of 96 randomly selected Sunit sheep were assigned to receive the basic diet or the basic diet supplemented with probiotics. The results showed that supplementation with probiotics significantly increased the loin eye area, and decreased plasma triglycerides and free fatty acids, increasing the content of intramuscular fat and triglycerides in the muscle and improving the composition of the fatty acids. The inclusion of probiotics in the diet reduced the expression of adenosine 5'-monophosphate-activated protein kinase alpha 2 (AMPKα2) mRNA and carnitine palmitoyltransferase 1B (CPT1B) mRNA, while increasing the expression of acetyl-CoA carboxylase alpha (ACCα) mRNA, sterol regulatory element-binding protein-1c (SREBP-1c) mRNA, fatty acid synthase mRNA, and stearoyl-CoA desaturase 1 mRNA. The results of this study indicate that supplementation with probiotics can regulate fat deposition and improves the composition of fatty acids in Sunit sheep through the signaling pathways AMPK-ACC-CPT1B and AMPK-SREBP-1c. This regulatory mechanism leads to an increase in intramuscular fat content, a restructuring of muscle composition of the fatty acids, and an enhancement of the nutritional value of meat. These findings contribute to a better understanding of the food science of animal resources and provide valuable references for the production of meat of higher nutritional value.

It has been reported that trans fat (tFA) may have adverse or beneficial effect depending upon the position and number of double bonds. The presence of tFA in human tissues and fluids is related to dietary intake, intestinal absorption, metabolism and storage, exchanges among compartments. This study investigated the effect of breads containing tFA, soybean or rice on postprandial plasma fatty acid and lipid composition. 33 healthy volunteers were divided into 3 groups and fed soybean bread, rice bread or wheat bread groups containing equivalent amounts of tFA (elaidic acid rich, 3.75 g/day), respectively. Postprandial lipid profiles at 0, 1, 2, 3 and 4 hours after a respective meal were studied. Plasma fatty acid was extracted by the method of Folch and methyl ester of fatty and prepared by acid transmethylation and analyzed by Gas Chromatography. Peaks were identified using pure reference compounds and quantified. Postprandial data indicated that consumption of soybean and rice breads with 3.75 g tFA retarded the appearance of C18:1 and C18:2 tFA in plasma lipid compared to that of wheat bread. Futhermore, soybean and rice bread groups showed lower plasma saturated fatty acid levels than wheat bread group. Postprandial TG level was significantly lowered in soybean bread group compared to that of rice and wheat bread groups. These results imply that soybean bread with high dietary fiber content and biologically active substances may inhibit or delay lipid absorption.

The effect of mixed onion pills on body composition, blood pressure, and concentrations of blood glucose and lipids were studied in 10 men ($38.11{\pm}2.82$ years old). The mixed onion pills was produced by mixing quercetin, onion, mulberry leaves and buckwheat. Ten volunteers (male, BMI 23.0~35.4 kg/$m^2$) were chosen for this study. The volunteers consumed 1.2 g of mixed onion pills (containing about 30 mg of quercetin) per day for 2 months. The administration of the mixed onion pills did not produce any weight and BMI changes in the subjects. The systolic blood pressure and the level of blood glucose were slightly lowered by the supplementation of the mixed onion pills. After 2 months both the concentration of plasma triglycerides and total cholesterol of the subjects were lowered by 12.4% and 5.0%, respectively (triglyceride; pre $251.67{\pm}45.63$ mg/dL vs. post $220.44{\pm}44.67$ mg/dL and total cholesterol; pre $207.25{\pm}10.39$ mg/dL vs. post $196.63{\pm}10.47$ mg/dL, p<0.05). These results suggest that the mixed onion pills may possibly lower the level of plasma lipids in overweight or obese men (BMI greater than 23 kg/$m^2$).

Effects of powdered pine needle (Pinus densiflora seib et Zucc) on serum and liver lipid composition and antioxidative capacity were investigated in rat fed high oxidized fat. Sixty male Sprague-Dawley rats weighing 161.25$\pm$2.51 g were blocked into four groups according to body weight and raised seven weeks with basal diet (normal group, I), basal diet and 10% oxidized fat (control group, II), basal diet, 10% oxidized fat and 2% powdered pine needle (2% powdered pine needle group, III) and basal diet, 10% oxidized fat and 3% powdered pine needle (3% powdered pine needle group, IV). Food intake, body weight gain and feed efficiency were not significantly different among oxidized fat diet groups. The level of plasma total cholesterol showed a tendency to decrease, whereas the plasma HDL-cholesterol concentration revealed a tendency to increase in pine needle groups. However plasma triglyceride level showed no significant differences in the treatment groups. Intake of the oxidized fat has increased the levels of liver cholesterol and triglyceride. The powdered pine needle showed a tendency to decrease thiobarbituric acid values in plasma and liver. The pine needle samples have also decreased the plasma GOT and GPT activities, whereas they have increased the liver glutathione peroxidase activity.

The influence of selenuium deficiency and fish oil on lipid peoxidation status and fatty acid composition of tissues(plasma aorta and liver) was studied. Male Sprague Dawley rats were fed for eight weeks semipurified diets containing 7% corn oil(by weight) or 5, 5% fish oil(MaxEPA) plus 1.5% corn oil with oil with or without selenium status (glutathione peroxidase activity and selenium levels) were significantly lower in the rats given inadequate selenium in plasma aorta (p<0.02 and p<0.001 respectively) gut not that in plasma Selenium supplementation decreased hepatic MDA levels(p<0.02) Increases in the levels of 20:5(n-3) 22:5(n-3), 22:6(n-3) 20:3(n-6) and a decrease in the level of 20:4(n-6) were observed in plasma total lipids and aortic and hepatic phospholipids when fish oil was fed. Though selenium supplementation increased the level of n-3 fatty acids(such as 22:6(n-3)) in plsama and the aorta is overall effect was smaller than the effect of fish oil feeding. These data suggest that selenium may play a significant but minor role in protecting against lipid peroxide-tion even when vitamin E intakes are in excess of current recommendations in both corn oil and fish oil diets.
