Hexane extract of Porteresia coarctata (Roxb.) exhibits a toxic effect on the tissues of Spodoptera litura (F) while fed at the dose of 1000 and 2000 ppm thoroughly mixing with castor leaves (Ricinus communis L) after dissolving in DMSO at late fourth instar whereas only DMSO treated castor leaves were fed to control group. The larvae were put to rear at $28^{\circ}C{\pm}1^{\circ}C$, $76{\pm}4%$ R.H. under 12 L + 12 D photoperiodic regime. In test group insects substantial reduction of protein and DNA content was marked in fat body and midgut tissues compared to DMSO treated control group. The significant biochemical alterations in the midgut tissues and fat body of test group insects indicate the insecticidal property of the said plant extract that could be tested in facilitating the phenomenal stride in Integrated Pest Management.

This study was carried out to effects of Allium victorials extract on lowering lipid, anti-oxidation and concentration of inflammatory mediators in rats fed high oxidized fat. Concentration of free fatty acid(FFA), triglyceride(TG), total cholesterol and LDL-cholesterol in plasma decreased in the Allium victorials extract groups and plasma HDL-cholesterol concentration revealed a tendency to increase in Allium victorials extract groups. Concentration of total cholesterol and TG in liver showed a tendency to decrease in Allium victorials extract groups. Concentration of thiobarbituric acid(TBARS) in plasma and liver showed a lower values in Allium victorials extract groups than that of control group. Activities of glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) and catalase(CAT) in liver showed a tendency to increase in Allium victorials extract groups. Concentration of nitrogen oxide(NO), ceruloplasmin and ${\alpha}1$-acid glycoprotein in plasma showed a lower values in Allium victorials extract groups than that of control group. These results indicate that the Allium victorials extract have an functional material for lowering lipid, anti-oxidation and anti-inflammatory effect.

Here we study the anti-obesity effects of by-product from soybean on mouse fed high fat diet. The body weight gain, visceral and subcutaneous adipose tissue weight, liver and epididymal adipose tissue weight in freeze-dried soybean-soaking-water (SSW) powder fed group showed lower level than those in high fat diet (HFD) group by determining with weight measuring and histological methods. Also, histological analyses of the liver and fat tissues of SSW grouped mice revealed significantly less number of lipid droplets formation and smaller size of adipocytes compared to the HFD group. Moreover, the levels of total serum cholesterol, LDL-cholesterol and the atherogenic index were decreased in the SSW groups. Especially, in SSW group, the levels of phosphorylation of two lipid oxidation enzymes, adenosine monophosphate-activated protein kinase (AMPK) and acetyl-CoA carboxylasse (ACC) were elevated hence that may activate fatty acid oxidation. But AST and ALT levels were not changed in blood. By micro-CT analysis of abdomen, SSW groups significantly showed a tendency to decrease visceral and subcutaneous fats as well as fat-deposited areas compared to HFD group. Taken together, we suggest that soybean soaking water has a function in ameliorating obesity through inhibiting lipid synthesis as well as stimulating fatty acid oxidation.

Effects of substituting olive, corn, soybean, and sunflower oils (each at 50% substitution) on chemical composition and sensory quality of beef hamburger patties were determined. Although beef patties added with plant oils were not different in chemical composition to control (added beef fat 10%), they had 2.0-3.8% lower caloric contents, 3.7-5.9% lower cooking loss, and less diameter and thickness changes after cooking. Beef patties with olive oil had lowest $L^*-values$ before and after cooking. In textural properties, control had higher hardness, cohesiveness, and gumminess than patties with plant oils, whereas no differences in springiness were observed between control nod all plant oil-treated patties. Beef patties containing olive oil had higher scores for overall acceptability than other patties.

This study used glucomannan as a fat substitute to produce low-fat patties with chicken meat, of which consumer consumption is increasing. In the case of a cooked meat patty, the crude fat content of the group treated with glucomannan was higher than that of a control when cooked. The cooking loss and reduction rate in the diameter of the control patties were higher than those of the group treated with glucomannan. Cohesiveness and chewiness of the group treated with glucomannan were higher than those of the control. As a result of sensory evaluation, there were no significant differences in the tenderness, color, odor and overall taste among the patties, but the juiciness of the group treated with glucomannan was lower than that of the control. There were no big differences in the pH of the patties during the frozen storage period. The volatile basic nitrogen (VBN) content of all of the types of patties gradually increased up to 7.97-8.56 mg% at the fourth week of storage, but these VBN values are hygienically safe. From these results, there was no large quality difference between a low-fat chicken patty to which glucomannan was added and a control. Therefore, it was confirmed that a good quality low-fat chicken patty can be made by controlling the fat and glucomannan content.

This experimental study was performed to evaluate the effects of ehtanol extract of Purple Solanum tuberosum L(EPSTL) on obesity and hyperlipidemia in rats induced by high fat diet. Sprague-Dawley rats were divided into normal group, control group, EPSTL (100 mg/kg and 200 mg/kg) treated group. EPSTL was orally administered to the obese rats by high fat diet for 6 weeks. The effect of EPSTL on obesity and hyperlipidemia were examined in vitro and in vivo as follows : EPSTL effectively inhibited the differentiation of 3T3-L1 adipocytes in a concentration dependent manner. EPSTL significantly lowered body weight of rats fe high fat diet for 6 weeks from 4 weeks treatment compared with untreated control. EPSTL significantly reduced the weight of retroperitoneal fat only at 100 mg/kg and epididymal fat pad in rats fed high fat diet for 4 weeks at 100 and 200 mg/kg. EPSTL significantly reduced the level of triglyceride at 200 mg/kg, while EPSTL tended to lower the levels of total lipid and phospholipid in rats fed high fat diet for 4 weeks with no significance. EPSTL significantly attenuated the level of total cholesterol, LDL and atherosclerosis index (Al) as well as increased the level of HDL at 200 mg/kg. EPSTL significantly reduced the levels of total lipid and triglyceride of hepatic tissues in rats fed high fat diet for 4 weeks at 200 mg/kg. EPSTL significantly lowered the level of insulin, while it did not affect leptin compared with untreated control. Taken together, these results suggest that EPSTL can be used for the treatment or prevention of hyperlipidemia and obesity.

The purpose of this study was to investigate the anti-apoptosis-related protein expression in skeletal muscle of rats with different amount of mountain ginseng (MG) added high-fat diet fed. Twenty-four Sprague Dawley male rats were divided into the high-fat diet control group (CON), 0.5% of MG added diet group (MG1), and 1.0% of MG added diet group (MG2) with eight rats each. The P53, anti-apoptotic protein, was significantly lower in MG2 than CON and MG1. The bcl-2 and bcl-xl, however, were not significantly different from MG1 but from CON. The caspase-9 and -3, were significantly lower in MG groups than CON. In addition, it was dramatically lower in MG2. These results suggested that MG addition to the high-fat diet suppressed p53 protein expression and enhanced anti-apoptototic protein expression. MG may be a positive effects on health as a medicinal plant.
