The lipid lowering and antioxidant effects of Gansoo(BL18), Pungji(GB20) and Eumnungcheun(SP9) acupuncture in rats fed high fat diet were analyzed in biochemical and molecular biological aspects. The results obtained from this study are as follows : 1. In the body weight reduction, all acupuncture groups showed a high reduction compared to those of control group and in acupuncture groups, Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a high reduction. 2. The concentration of plasma triglyceride, total cholesterol and LDL-cholesterol with acupuncture groups showed a little decrease and in acupuncture groups, Gansoo(BL18) and Pungji(GB20) groups showed a low values compared to those of other acupuncture groups. However, the tendency of HDL-cholesterol concentration showed no significant different. 3. The concentration of plasma ${\beta}-lipoprotein$ and free fatty acids showed a lowest values in the Gansoo(BL18) and Pungji(GB20) acupuncture groups and the glucose concentration showed to decrease in all treated acupuncture groups. 4. The concentration of liver total cholesterol and triglyceride in Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a lower values than those of control group. 5. In all the acupuncture groups, the plasma glutamic oxaloacetic transaminase(GOT) activity showed a little decrease. In the glutamic pyruvate activity(GPT), Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a lower values than those of control groups. However the values of eumneungcheun acupuncture only group showed no significant difference to those of control group. 6. The plasma and liver Thiobabituric acid reactive substance (TBARS) concentration in Gansoo(BL18) and Pungji(GB20) acupuncture groups were a lower than those of control group. However the values of eumneungcheun acupuncture group showed no significant difference to control group. 7. The superoxide dismutase (SOD) activity in Gansoo(BL18) acupuncture group and Glutathione peroxidase (GSH-Px) activity in Gansoo(BL18) and Pungji(GB20) acupuncture groups showed a high values. The catalase (CAT) activity in all the acupuncture groups showed a higher values than those of control group. 8. In acupuncture groups, DNA expression of Apo-B and Apo-E showed a tendency to decrease, however DNA expression of leptin showed no significant difference in all treatment groups. DNA expression of $TNF-{\alpha}$ showed a increase in acupuncture groups. These results indicate that Gansoo(BL18) and Pungji(GB20) (especially Gansoo(BL18)) acupuncture affect the lipid metabolism and showed possibility of lowering adipose tissue mass and lipid peroxidation.

This study was designed to examine the effects of fractions of ethanol extract of Benincasa hispida (wax gourd) on plasma glucose and lipid levels in streptozotocin (STZ) induced diabolic rats. sprague-Dawley rats were induced diabetes mellitus by STZ injection (45 mg/kg) into the tail vein and were divided into 5 groups: normal, STZ-control, three experimental diabetic groups. fractions of ethanol extract of Benincasa hispida were administered orally into the diabetic rats for 14 days. The food intake and body weight were monitored and plasma levels of glucose, cholesterol, HDL-cholesterol, triglyceride (TG) , free fatty acid (FFA) , and aminotransferase activity were analyzed. A significant lowering effects of plasma glucose levels were observed in the chloroform fraction and $H_2O$ fraction group compared to STZ-control group at 14 days. Administrations of each of the three fractions decreased plasma TG and FFA levels in diabetic rats. Activity of alanine aminotransferase (ALT) in $CHCl_3$ fraction and $H_2O$ fraction groups and aspartate aminotransferase (AST) in $H_2O$ fraction group significantly lower than STZ-control group. The results show that $CHCl_3$ fraction of Benincasa hispida could be effective to control the STZ-induced diabetic rats. (Korean J Nutrition 38(10): 801$\sim$806,2005)

This study examined the effects of com gluten (CG) and its hydrolysate consumptions on weight reduction in rats fed a high-fat diet. Eight-month-old male Sprague-Dawley rats (n=40) were fed a high-fat diet (40% calorie as fat) for 4 weeks. They were then randomly divided into four groups and fed the isocaloric diets with different protein sources for 8 weeks. The protein sources were casein (control group), intact CG (CG group), CG hydrolysate A (CGHA group, 30% of protein as peptides and 70% as free amino acids) and CG hydrolysate P (CGHP group, 93% of protein as peptides and 7% as free amino acids). Body weight gain, adipose tissue weights, nitrogen balance, absorptions of energy, protein and fat, lipid profiles in plasma, liver and feces and hepatic activities of camitine palmitoyl transferase (CPT), fatty acid synthase (FAS), malic enzyme (ME) and glucose-6-phosphate dehydrogenase (G6PDH) were assessed. The CGHA diet had the highest amount of BCAAs, especially leucine, and most of them existed as free amino acid forms. The CGHA group showed significant weight reduction and negative nitrogen balance. Protein absorption and apparent protein digestibility in the CGHA group were significantly lower than those in other groups. Adipose tissue weights were the lowest in the CGHA group. Activity of CPT tended to be higher in the CGHA group than in other groups and those of FAS, ME and G6PDH were significantly lower in the CGHA group than in other groups. In conclusion, the CGHA diet which had relatively high amounts of free amino acids and BCAAs, especially leucine, had a weight reduction effect by lowering adipose tissue weight and the activities of FAS, ME and G6PDH in experimental animals, but it seemed to be a negative result induced by lowering protein absorption, increasing urinary nitrogen excretion and protein catabolism.

We studied the difference effects of dietary ${\alpha}-linolenic\;acid\;({\alpha}-LA,\;18:3\;n-3)$, eicosapentaenoic acid (EPA, 20:5 n-3) and docosahexaenoic acid (DHA, 22:6 n-3) on the lowering of triacylglycerol in the liver and serum on lipid metabolism in rats. Rats were fed semipurified diets containing 10% fat with constant polyunsaturated/monounsaturated/saturated fatty acids (1:1:1) and n-6/n-3 ratio (1:2). EPA (98%) and DHA (98%) were added in diets as the ethyl esters. The concentration of liver triacylglycerol was significantly lower in rats fed both EPA and DHA than in those fed ${\alpha}-LA$. The concentration of liver phospholipid was significantly higher in rats fed DHA than in those fed ${\alpha}-LA$ and EPA. Both EPA and DHA reduced serum triacylglycerol concentration compared with ${\alpha}-LA$, but this effect was more pronounced in the EPA diet. The activity of phophatidate phosphohydrolase in the liver microsome was significantly lower in rats fed both EPA and DHA than in those fed ${\alpha}-LA$. but, there was no significant difference on the activities of diacylglycerol acyltransferase among the three groups. The concentration of liver triacylglycerol were correlated with changes in the microsomal phosphatidate phosphohydrolase activity (r=0.84). Hepatic NADPH generating enzyme, glucose-6-phosphate dehydrogenase was more effective to reduce the activity in rats fed both EPA and DHA than in those fed ${\alpha}-LA$. In conclusion, EPA or DHA reduced the hepatic triacylglycerol concentration by inhibiting microsomal phosphatidate phosphohydrolase, thereby inhibiting synthesis of triacylglycerol in the liver.

As the average span of human life is continuously increasing, especially the old aged groups, are suffering from various chronic and critical diseases e.g. cardiovascular diseases, coronary heart disease, diabetes, atherosclerosis and alzheimer's etc. However, effective and safe treatment methods have not yet been investigated threathening old aged groups. This research was planned to isolate compounds with the therapeutic potential for the above mentioned chronic diseases from the mulberry leaves. Biological screenings were carried out for the following categories; anti-atherogenic, anti-diabetic and antihypertensive effects. The results were as follows; Mulberry leaves, 20% $\alpha$-treated Gaelyrangppong showed significant 81% of blood glucose lowering effects in alloxan-induced hyperglycemic mice. Particularly, butanol-soluble fractions of mulberry leaves showed the more significant hypoglycemic activity than other fractions in alloxan induced hyperhlycemic mice. Also in the group given 1g/kg doses of extract of mulberry leaves, total cholesterol level was decreased significantly by as much as 49% in hyperlipidemia-induced rats. In Mulberry leaves post-treated group, the atheroscelosis index, HDL-cholesterol/Total-cholesterol, was increased significantly by as much as 91%.

The present study was undertaken to elucidate the mechanisms underlying the cholesterol-lowering effect of S-allylmercaptocysteine (SAMC) derived from aged garlic. Rat hepotocytes and HepG2 cells were used to determine the short-term effects of SAMC on [$^{14}C$] acetate incorporation into cholesterol, and several enzymatic steps. The cells were grown in Dulbecco's modified Eagle's medium supplemented with 10% fetal bovine serum and treated with 20, 40, 60 and 80 ${\mu}g/ml$ of SAMC. At concentration of 20~40 ${\mu}g/ml$, no significant cells viability effect was noted during those incubation periods. However, at a concentration 60 ${\mu}g/ml$, cell viability decreased approximately 50% compared with the control. The treatment of cells with 5, 10, 15, and 20 ${\mu}g/ml$ of SAMC resulted in a marked of [$^{14}C$]-acetate incorporation into cholesterol. At concentration of 15 ${\mu}g/ml$, the cholesterol synthesis was inhibited 79% in cells. The activities of lipogenic enzymes, fatty acid synthase (FAS), and glucose-6-phosphate dehydrogenase (G3PDH) were measured in culture hepatocytes treated with the inhibitors. The activity of FAS in cells treated with 0.95 nmol SAMC was 19% lower than that of nontreated cells, and no affected G6PDH activity, 3-hydroxy-3-methylglutaryl Co A activity was decreased at concentration dependant manner. The present study demonstrates that SAMC is effective in inhibiting cholesterol biosynthesis.

A released exopolysaccharide (rEPS)-producing strain (LM187) with good acid resistance, bile salt resistance, and cholesterol-lowering properties was isolated from Sichuan paocai and identified as Leuconostoc mesenteroides subsp. mesenteroides. The purified rEPS, designated as rEPS414, had a uniform molecular weight of 7.757 × 10⁵ Da. Analysis of the monosaccharide composition revealed that the molecule was mainly composed of glucose. The Fourier transform-infrared spectrum showed that rEPS414 contained both α-type and β-type glycosidic bonds. ¹H and ¹³C nuclear magnetic resonance spectra analysis showed that the purified rEPS contained arabinose, galactose, and rhamnose, but less uronic acid. Scanning electron microscopy demonstrated that the exopolysaccharide displayed a large number of scattered, fluffy, porous cellular network flake structures. In addition, rEPS414 exhibited strong in vitro antioxidant activity. These results showed that strain LM187 and its rEPS are promising probiotics with broad prospects in industry.

This study was carried out to examine the effects of pills made of mulberry leaves and silkworm powder on lowering blood glucose level. Experimental animals were Sprague-Dawley male rat weighing 100$\pm$10 g and pills were supplemented with 0.4% (4 g/kg) diet. Experimental groups were assigned to diabetic group (DM group) and pill supplemented groups. Pill supplemented groups were classified 100% mulberry leaves (M group), mixing 25% silkworm powder to mulberry leaves (25SM group), mixing 50% silkworm powder to mulberry leaves (50SM group), mixing 70% silkworm powder to mulberry leaves (75SM group) and 100% silkworm powder (100S group). Experimental diets and water fed ad libitum, and streptozotocin was injected to induce diabetic state after 3rd weeks and sacrificed on the 9th day. The contents of 1-deoxynojirimycin(DNJ) were increased with adding the silkworm powder. The contents of GABA and rutin were increased with adding the mulberry leaves. In vitro, intestinal mucosa $\alpha$-glucosidase inhibitory activities were significantly increased in pills which mixed with silkworm powder by 50%. Blood glucose levels were high in groups which mixed with silkworm powder by 50% compared to DM group. Intestinal mucosa maltase activity in proximal part was significantly reduced in pill supplemented group compared to DM group and pill supplemented groups were no significant difference. Enzyme activity in middle part was no significant difference in experimental groups. Enzyme activity in distal part was decreased in pill supplemented groups, especially in 50SM, 75SM and 100S groups were significantly reduced compared to DM group. Sucrase and lactase activities in pill supplemented groups were significantly reduced at proximal part, and there was no significant difference in middle and distal parts. In conclusion, pills made of mulberry leaves and silkworm powder increased the $\alpha$-glucosidase inhibitory activity in vitro and reduced the blood glucose levels by controlling the disaccharidase activities of intestinal proximal part in STZ-induced diabetic rat. The synergistic effect was the highest when mulberry leaves was mixed with silkworm powder by the ratio of 50 : 50.
