The effectsof garlic vinegar supplementation on body weight, blood blucose, and plasma triglyceride and cholesterol were investigated in streptozotocin -induced diabetic rats fed high-cholesterol(1%) diet for 4 wk. The garlic vinegar was made by fermenting 20% frsh garlic juice. There was no effect of garlic vinegar on body weight, plasma glucose or triglyceride concentrations in the diabetic rats. Plasma total -cholesterol concentrations were unaffected by garlic vinegarr supplementation. However, plasma LDL-cholesterol concentrations and atherogenic index were significantly lower in the diabetic rats supplemented with garlic vinegar diet than tin the cotnrol rats. The diabetic-rats supplemented with garlic vinegar not only had increased HDL-cholesterol levels but had decreased LDL-cholesterol. This alteration in the HDL/LDL-cholesterol ratio in the diabetic rats may decrease the risk of atheroscelrosis. Therefore, the over-all effect of garlic vinegar supplement may contribute to the antiatherogenic role in streptozotocin-induced diabetic rats.
A Gram-negative, aerobic, motile by gliding, and rod-shaped marine bacterium, designated CE67T was isolated from the marine sponge Callyspongia elegans on Biyang-do in Jeju Island. The CE67T strain grew optimally at 25℃, pH 7.5, and in the presence of 2-3% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain CE67T was related to the genus Aureivirga and had the highest 16S rRNA gene sequence similarity to the Aureivirga marina VIII.04T type strain (96.3%). The primary fatty acids (>10%) of strain CE67T were iso-C15:0 (35.3%) and iso-C17:0 3OH (21.8%). The polar lipid profile of strain CE67T contained phosphatidylethanolamine, unidentified aminolipids, and unidentified lipids. The predominant menaquinone was MK-6. The DNA G+C content was 29.1 mol%. Based on the polyphasic taxonomic analysis, strain CE67T was determined to be a representative novel species of the genus Aureivirga for which we propose the name Aureivirga callyspongiae sp. nov., whose strain type is CE67T (=KCTC 42847T=JCM 34566T).
Present study was conducted to investigate the effects of exercise and cholesterol diet on plasma and liver lipids, platelet aggregation, erythrocyte Na efflux and liver index such as GOT and GPT using Sprague Dawley rats. Forty rats were divided into four groups and fed control or 0.5% cholesterol diet with and without treadmill for six weeks. The final body weight of group fed cholesterol diet with exercise was somewhat decreased compared with group fed cholesterol diet without exercise. L.W/B.W ratio was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise tended to decrease this ratio. Plasma total cholesterol was significantly increased and HDL-cholesterol was decreased in groups fed cholesterol diet (p < 0.01). Plasma triglyceride was significantly decreased in groups fed cholesterol diet compared with groups fed control diet (p < 0.01). Plasma triglyceride of groups with exercise was significantly decreased compared with their non exercising counterparts regardless diet (p < 0.05). Liver total cholesterol and triglyceride was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise did not affect on these levels. Na-K ATPase was somewhat decreased in groups fed cholesterol diet, and exercise tended to recover the reduced Na-K ATPase. Na passive transport was significantly decreased in group fed control diet without exercise and significantly increased in group fed cholesterol diet with exercise, there were significant differences between groups (p < 0.05). There were no differences in total Na efflux and intracellular Na among groups, and total Na efflux was not correlated with intracellular Na. Hematocrit was significantly lower (p < 0.05) in group fed cholesterol diet without exercise compared with other groups. Platelet aggregation in the initial slope and the maximum was increased in groups fed cholesterol diet, but not statistically significant. Exercise especially increased the initial slope of aggregation. Plasma GOT and GPT was significantly increased in groups fed cholesterol diet (p < 0.01), and exercise in group fed cholesterol diet significantly decreased both GOT and GPT compared with the non exercising counterpart (p < 0.01). This study showed that cholesterol diet increases plasma and liver lipids and GOT and GPT, and exercise improves plasma and liver lipid profile and liver index of GOT and GPT preventing fatty liver.
The effect of benzyladenine (BA) on lipid peroxidation and compositions of total insoluble proteins and chloroplast thylakoid protein from wheat primary leaves during senescence in the dark was studied. BA ($10^{-5}\;M$) treatment prevented conspicuously the loss of chlorophyll content and soluble and insoluble leaf protein contents in senescing wheat leaf segments during 4-day dark incubation. Under the BA treatment, especially, the level of insoluble protein was highly maintained than that of soluble protein. Also, the increase of malondialdehyde (MDA: the peroxidation product of membrane lipids) content was inhibited in the BA treated leaves. Three major polypeptide bands in quantity corresponding to 57, 26 and 12 KD molecular weight were clearly resolved with other minor bands by SDS-polyacrylamide gel electrophoresis (SDS-PAGE) in the insoluble protein fraction. The insoluble protein profiles of the control leaves showed a remarkable decrease in the intensity of the 57 and 12 KD band except for 26 KD band in the 72 h dark incubation. This loss during dark incubation was reduced by BA treatment. More than 20 polypeptides were resolved in the chloroplast thylakoid membrane fraction with the most prominent bands which are 59 and 57 KD ($\alpha\;and\;\beta$ subunit of coupling factor: CF) and 26 KD (apoprotein of LHCP). The changes in thylakoid protein profile during 72 h dark incubation showed the rapid degradation in control, but this degradation was prevented in quantity by BA treatment. The above results suggested that BA would inhibit the peroxidation of membrane lipids, thereby preventing the loss of membrane proteins which led to the maintenance of the membrane integrity including chloroplast thylakoid.

The study aimed to investigate the anti-obesity effects of 1% Rhus verniciflua vinegar (RV) supplementation in high-fat-diet (60% fat)-induced obese rats. A total of 50 4-wk-old male Sprague-Dawley rats were fed normal chow diet or maintained on high-fat diet (HFD) for 12 weeks to induce obesity and were then randomized into five groups as follows: normal diet+ultra-pure water (CON), HFD+ultra-pure water (OB-DW), HFD+1% acetic acid (OBAA), HFD+1% RV (OB-RV), and HFD+0.1% caffeine (OB-CF). AA was used as a control for RV, and caffeine was used as a positive control due to its weight reducing effect. After 2 months, body weight, organ and adipose tissue weights, serum lipids, hepatic lipids, adipocyte size, and cell number per spot level were analyzed. As a result, food efficiency ratio, abdominal adipose tissue weight, serum levels of total cholesterol, triacylglycerol, free fatty acids, coronary artery index, and fecal lipid were significantly reduced in the RV treatment group. In this study, we found that dietary RV improved obesity by increasing lipid excretion and reducing lipogenesis. These results suggest that RV has potential as a functional anti-obesity food.

To evaluate an effect of dietary protein on lipoprotein profile serum of carbon tetrachloride-treated rats, carbon tetrachloride (50% in olive oil) was twice given at 0.1ml/100g body weight at intervals of 24hours to the male rats and then the degree of liver damage in carbon tetrachloride-treated animals fed a low protein diet was compared with that fed a high protein diet. The increasing rate of liver weight/body weight and the serum levels of alanine aminotransferase in carbon tetrachloride-treated rats to the control group were higher in rats fed high protein diet than those fed low protein diet. In the serum levels of lipid (total lipid, total cholesterol and triglyceride) remarkable differences were not found between low protein diet group and high protein diet group. But these serum lipids in carbon tetrachloride-treated rats were decreased and the decreasing rate of serum lipids to control group were higher in carbon tetrachloride-treated rats fed high protein diet than those fed low protein diet. Under the animal model as identified by the present data herein, serum pre $\beta$-lipoprotein and $\alpha$-lipoprotein fractions were decreased in carbon tetrachloride-treated rats, but the serum levels of $\beta$-lipoprotein were rather increased in the both group by the injection of carbon tetrachloride. Especially, the decreasing rate of $\alpha$-lipoprotein fraction was higher in $CCl_4$-treated rats fed a high protein diet than those fed a low protein diet to its control group and the increasing rate of serum $\beta$-lipoprotein fraction was also higher in $CCl_4$-treated rats fed high protein diet than those fed low protein diet.
Antioxidant vitamin supplementation focuses one's attention on the prevention of age-related diseases. This study was conducted to investigate the antioxidant status and lipid profiles and to look into the antioxidant vitamin supplementation that affects lipid metabolism in 20 elderly non-smoking Korean women (placebo group: n = 6, vitC suppl: n = 7, vitE suppl: n = 7). Age, height, weight, muscle, percent of fat and WHR were not significantly different among the groups, however $\%$ of fat was above $33\%$ and WHR was above 0.9. And blood pressure of the placebo group was 131.7/81.7 (border line hypertension), that of vitamin C supplement was 141.4/87.1 (hypertension) and that of vitamin E supplement was 151.4/92.9 (hypertension). Although nutrient intakes of all groups were poor, antioxidant status (blood vitamins C, E, A, and beta-carotene) and lipid profile (TG, total-cholesterol, VLDL-cholesterol, LDL-cholesterol, HDL-cholesterol) were normal. For nutritional intervention, the vitamin C supplement group received L-ascorbic acid 1,000 mg, and vitamin E supplement group received d-alpha-tocopherol 400IU for 4 weeks, showing the effects of vitamin E supplementation. Response total cholesterol of HDL-cholesterol (T-Chol/HDL) in vitamin E supplement group was significantly decreased from 4.3 to 3.2. And response LDL-cholesterol of HDL-cholesterol (LDL/HDL) in the vitamin E supplement group was also significantly decreased from 2.6 to 1.7. In addition, after the adjustment for plasma lipids (TG, total cholesterol), plasma vitamin A levels in vitamin E supplement group were significantly increased from 7.89 mg/g to 14.91 mg/g. And systolic blood pressure in vitamin E supplement group was significantly reduced. These results suggested that vitamin E supplementation affects the lipid profiles and blood pressure in elderly non-smoking women. So various nutrition programs must be implemented against age-related diseases and further studies are needed regarding sorts and amounts of antioxidant nutrients and supplementation periods.
Dietary fatty acid including mainly palmitic acid and stearic acid was fed to fattening cattle and its effect on body weight gain, plasma lipid contents and rumen liquid fermentation in vitro was examined. In expt. 1, the effect of dietary fatty acid on body weight gain and plasma lipid concentrations was examined. In the control diet group, cattle were fed 1 kg/day of rice straw and concentrate which satisfied the requirement. In the fatty acid group, cattle were given 250 g/d of fatty acid with the same diet of the control diet group. In the excess concentrate group, cattle were given the same diet of the control diet group plus 735 g/d of concentrate corresponding to the same TDN of 250 g/d of fatty acid. Diets were given for 7 days. Body weight gain of cattle given dietary fatty acid was significantly greater than that of cattle fed only rice straw and concentrate. When dietary fatty acid was added to cattle feed, plasma NEFA and HDL-cholesterol concentrations increased. In expt. 2, the influence of dietary fatty acid on gas production and VFA profile in the rumen liquid was investigated in vitro. In the control group, 10 mg of rice straw and 90 mg of concentrate were incubated in the rumen fluid. In the excess concentrate group, 10 mg of rice straw and 97.5 mg of concentrate were incubated. In the fatty acid group, 10 mg of rice straw, 90 mg of concentrate and 2.5 mg of fatty acids were incubated. The rumen liquid mixed with feed materials was incubated for 24 h and the cumulative gas volume was measured. The VFA profile was also measured. Cumulative gas volume in the rumen liquid with fatty acid was equal to the control. Excess concentrate increased cumulative gas volume compared to the fatty acid group. There was no significant difference in total VFA concentration between experimental diet groups. It is suggested that dietary fatty acid has the potency to improve growth performance in fattening cattle without failure in rumen fermentation.

There is a unique type of fatty acid in the hair surface. 18-methyleicosanoic acid (18-MEA) is an unusual anteiso fatty acid covalently linked to the outermost surface of hair cuticle. A layer of 18-MEA is located in the upper ${\beta}$-layer of the CMC that is responsible for the low surface energy and low friction resistance of the hair's outer surface. The high mobility of 18-MEA molecule facilitates spreading of extraneous lipid by decreasing interfacial shear strength. In this study, we introduced N-hydroxyl succinimidyl ester functional group to the one end of C10 - 40 isoalkyl acid for regenerating hair surface with covalently bound fatty acid layer. The re-hydrophobicization of hair surface has been investigated by contact angle measurement. The inner moisture content of hair at different levels of humidity (40, 55, 70 %RH) was measured by electric moisture analyzer. Treatment with Hydroxysuccinimidyl C10 - 40 Isoalkyl Acidate (HCIA) was supposed to make hair surface smoother by filling the cracks between cuticles with covalently bound fatty acid monomolecular layer like cuticle glue. This glue effect was also confirmed with line profile of AFM images. Therefore, the moisture and structural components of inner hair were not easily flown out and the optimum moisture content could be kept constantly though the outside humidity level was changed. The lateral force microscopy (LFM) by using atomic force microscope showed that the friction force of hair surface treated with HCIA was decreased. It also showed the constantly sustained friction value even after shampooing repeated 15 times.

The current study was carried out to investigate the effect of oral administration for 30 days of the Jijang kimchi extracts on prevention of diabetes, alcoholic liver injury and reduction of blood lipids in laboratory rats with alcoholic liver injury and diabetes induced by streptozotocin. In a diabetic model animals, the blood lipid profile, ALT, and AST levels were lower in kimchi extract groups compared to DC (diabetes control) group, and blood glucose level of DCJK (DC+oral administration with Jijang kimchi extracts) group was lower than that of DCCK (DC+oral administration with commercial kimchi extracts) group. Insulin levels were increased in order of NC (normal control), DCJK > DCCK > DC groups. In alcoholic liver injury model animals, ALT, AST and bilirubin were lowed in order of AC (alcohol group received 1 bottle of soju) > ACCK (1 bottle of soju plus oral administration with commercial kimchi extracts) ACJK (AC plus oral administration with Jijang kimchi extracts) > NC groups. In the clinical pathologic findings of liver tissue, AC group was severely injured, and tended to be improved in groups eating a 1 bottle of soju plus oral administration with kimchi extracts, especially Jijang kimchi extract group. The results suggest that eating Jijang kimchi can improve insulin secretion ability while lowering blood lipid profile, blood sugar and ALT, AST, and bilirubin levles in diabetic and alcoholic liver injury model animals.
