This study investigated the effects of soyoligosaccharide consumption on lipid profile of plasma, liver and feces and immune responses in Sprague-Dawley male rats. Sixty male Sprague-Dawley rats 4-wk-old were provided the soyo-ligosaccharide containing diets for 4 weeks (0, 100 g/kg diet); each of these diets was supplemented with either 70 or 200 g fat/kg diet, giving a total of 4 experimental groups. The effect of weight reduction was most significantly observed in the group fed low fat and soyoligosacchairde diet. The plasma total lipid and cholesterol contents were not changed by either fat proportion or soyoligosaccharide supplementation in the diets. Also the plasma triglyceride lowering effect by soyoligosaccharide was not observed in rats fed either low fat or high fat diet. However, the significant decrease in TG contents was found with rats fed high fat diets compared to the control/no soyoligosaccharide diet. Elevation of plasma LDL-cholesterol and reduction of HDL-cholesterol by feeding high fat diet was not altered by supplementing soyoligosaccharide. This was also applied to the liver lipid profiles. The significant increases in liver total lipid, trigly-cerides and cholesterol by high fat diet was not abolished by feeding soyoligosaccharide. However, the desirable effects of feeding soyoligosaccharide were found with total lipid and cholesterol excretion through feces in rats fed high fat diets. Immune organ weights and spleen cell proliferations did not affected by experimental diets. These results de-monstrated that soyoligosaccharide intakes increased the lipid output via feces, especially in rats fed the high fat diet, but more researches are needed on immune responses.

The purpose of this study was to examine the effects of taurine supplementation on serum lipidperoxide(TBARS), a risk factor for cardiovascular disease. The subjects were 22 healthy middle-aged women(33 to 54 years). Serum lipids, thiobarbituric acid reactive substances(TBARS), and plasma taurine levels were measured before and after supplying 3 g of taurine per day for 4 weeks. Plasma taurine was analyzed by Dabsyl-Cl(4-dimethylamino azobenzen-4-sulfonyl-chloride) derivatization and reversed-phase HPLC. Serum TBARS was measured by the Yagi method. Daily dietary taurine intake was calculated by food frequency questionnaire method. The weight and height means of the 22 subjects were $57.9{\pm}5.2$ kg and $159.2{\pm}5.2$ cm, respectively. Their percent body fat and waist/hip ratio(WHR) were 26.8% and 0.84, respectively, which were slightly higher than the average for middle-aged Korean women. Serum TC, TG and LDL-C levels tended to decrease after taurine supplementation, but HDL-C was not changed. A positive correlation between plasma taurine and HDL-C was shown after taurine supplementation. The serum TBARS concentration was significantly decreased from $5.05{\pm}0.84nmol/d{\ell}$ to $4.17{\pm}0.64nmol/d{\ell}$ after taking taurine(p<0.01), and the plasma taurine concentration was significantly increased from $63.7{\pm}14.2{\mu}mol/{\ell}$ to $73.8{\pm}16.6{\mu}mol/{\ell}$ after taurine supplementation(p<0.05). The average dietary intake of taurine was $178.5{\pm}50.4$ mg/day, which is similar to the average daily taurine intake of Korean women. In conclusion, taurine is an effective nutrient that antagonizes TBARS levels. Therefore, this study suggests that a sufficient taurine intake may be an effective way to prevent cardiovascular disease such as atherosclerosis.

Objectives The purpose of this study was investigating effects of Jengjengamiyijin-tang (zhengzhuanjiaweierchentang) (JGYT) on lowering lipid, antioxidation and production of inflammatory mediators being used rats fed on high oxidized fat. Methods We divided fat Sprague-Dawley rats fed on high oxidized into 4 groups. Each of 8 rats was divided into a control group and experimental groups. We fed a control group of rats a basal diet and administered normal saline (100 mg/kg, 1 time/1 day) for 4 weeks. And We fed each experimental group of rats basal diet and administered an extract of JGYT extracts (100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid of plasma and liver, concentration of proinflammatory cytokines, antioxidative activity and plasma tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), plasma interleukin-6 (IL-6), Apo-B, Apo-E and Leptin gene expression. Results 1. Concentration of plasma FFA, LDL-cholesterol, plasma and liver total cholesterol showed a significant decrement in JGYT groups. However, concentration of plasma HDL-cholesterol showed a significant increment in JGYT groups. 2. Concentration of plasma and liver TG, TBARS showed a significant decrement in JGYT groups. However, concentration of liver GSH-Px, SOD and CAT showed a significant increment in JGYT groups. 3. Plasma GPT activity and concentration of plasma IL-6, TNF-${\alpha}$, NO, Ceruloplasmin, ${\alpha}1$-acid glycoprotein showed a significant decrement in JGYT groups. 4. In the analysis of RT-PCR, gene expression of Apo-B and Apo-E in the JGYT groups showed a low expression than that of control group. However, the gene expression of leptin showed no difference in all the treatment groups. 5. The ratio of leptin expression per ${\beta}$-actin expression showed no significant difference among all treatment groups. However, The ratio of Apo-B and Apo-E expression per ${\beta}$-actin expression showed a significant decrement in JGYT groups. Conclusions According to this study, extract of JGYT showed a positive effect in lowering lipid, antioxidation and control of inflammatory mediators production.

본 연구는 고지방식이로 유도된 제2형 당뇨 동물모델에서 잠상산물의 항당뇨 및 지질개선 효과를 규명하기 위하여 C57BL/6N 마우스에 14주간 잠상산물 분말(ML, SK, MF, CT)을 급여한 후 제2형 당뇨의 임상적 지표 및 인슐린 신호 전달체계에 미치는 영향을 분석하였다. HFD군보다 잠상산물을 급여한 군들의 체중증가량이 감소하는 경향이었으며, 혈장 포도당 및 인슐린 농도는 HFD군보다 ML분말을 급여한 군에서 특히 감소하였다. 혈장 T-C 농도는 HFD군에 비하여 ML과 SK 분말 급여 군에서 유의적으로 감소하였으며, 혈장 HDL-C 농도 및 HTR은 HFD군보다 ML군과 SK군에서 현저히 증가하였다. 간 조직 지질 농도는 HFD군보다 잠상산물을 급여한 네 군 모두에서 TG와 T-C 농도의 유의적인 감소가 나타났다. 이상의 결과 잠상산물 중 ML분말이 혈장 포도당, 인슐린, T-C 및 TG 농도를 가장 효과적으로 감소시켰으며, 혈장 HDL-C 농도 및 HTR은 증가시켰다. 또한, 내장지방 조직의 AKT, S6K, 그리고 AMPK의 활성도 증가시킨 것으로 보아 고지방식이에 의한 인슐린 저항성 및 지질 대사를 개선한 것으로 생각된다. 향후 ML의 인슐린 저항성 개선 효과에 대해 더 깊이 있는 기전연구가 수행된다면 제2형 당뇨환자를 위한 건강기능성 식품으로 개발될 수 있을 것으로 생각한다.

The cholesterol-lowering effects of soymilk fermented with Bacillus subtilis KCCM42923 were studied in apolipoprotein E knockout (ApoE KO) mice and compared to the cholesterol-lowering effects of soymilk to which cheonggukjang powder had been added. ApoE KO mice were divided into 3 groups (n=7/group). Animals were fed either an atherogenic diet only (AD, control group), an AD supplemented with fermented soymilk containing Corni fructus (FSM group), or an AD supplemented with soymik to which cheonggukjang (CGJ) powder had been added at 5% (w/v) (CPS group) for 8 weeks. The amount of FSM or CPS supplementing the AD was 20.8 mL/kg BW. There were no differences in either body weight gain or organ weights among three groups. In the FSM group, the concentration of plasma total cholesterol (TC) and LDL cholesterol (LDLC) were significantly decreased by 26.2% and 30.3% compared with the values of the control group (p<0.05). However, the triglyceride (TG) and HDL-cholesterol (HDLC) levels were not affected. These beneficial effects of FSM on suppressing the increase in plasma cholesterol level by AD were greater than those of CPS, which revealed 15.4% and 16.4% inhibition for TC and LDLC, respectively. However, these differences between FSM and CPS groups were not significantly different. A preventative effect of FSM or CPS on the accumulation of hepatic TC, but not on TG, was observed. FSM and CPS did not demonstrate any effects on fecal lipid excretion. In conclusion, the cholesterol-lowering effects of the soymilk fermented with Bacillus subtilis KCCM42923 were comparable to CGJ powder-added soymilk. These results suggest that drinking FSM might provide beneficial effects on controlling plasma cholesterol levels.

Panax ginseng C.A. Meyer (Panax ginseng) has been used for several thousand years to prolong longevity in Asian countries. Ginsenosides are the most active components isolated from ginseng and belong to damarane saponin which are separated into protopanaxadiol and protopanaxtriol. To evaluate the complex effect of ginsenoside in apo E null mice, ginseng extract were intraperioneally (i.p.) injected and provided high-cholesterol diet for 12 weeks. Ginseng extract came from were i.p. injected with dose of 100 mg/kg/day for 4 weeks in the last experimental duration. Ginseng extract used experiment was abundant Rb1, Rc, Re, and Rg1 and PD：PT ratio was 1.2. The high-cholesterol diet induced liver damage was significantly reduced by ginseng extract. Results from plasma lipid profiles and atherogenic index were improved by ginseng extracts. The GE group significantly decreased plasma TG and TC by 73% and 61% compared to apo E (-/-) group. Also ginseng extract tend to decrease lipid profiles and lipidperoxidation contents in liver and heart. Ginseng extract with an abundant amount of Rg1 significantly suppressed the apoptosis induction of cardiac tissue. In conclusion, ginseng extract (PD：PT = 1) was improved lipid profiles and anti-oxidant effects.

A nutrition survey regarding daily kimchi consumption and its hypolipidemic effect were carried out with 102 of healthy Korean adult men aged between 40 to 64 years old who visited hospital for physical examination. The physical and biochemical parameters of blood were examined as well as food record, preferences for taste, personal life habit, and family history of disease. Data were expressed as quartile according to kimchi consumption. The average daily kimchi consumption for 1st, 2nd, 3rd, and 4th per centile group were 68, 118, 208, and 383g, respectively. The intakes of dietary fiber and Ca were found to be increased as kimchi intake increased(p<0.05). The kimchi consumption level was selected as the determining factor for HDL C level analyzed by stepwise multiple regression(p=0.09). When correlation coefficient between kimchi consumption and other parameters were analyzed, kimchi consumption was positively correlated with HDL C and negatively correlated with LDL C(p<0.05). The preference for hot taste was negatively correlated with systolic blood presure. It seems that kimchi consumption is beneficial to elevate HDL C and lower LDL C level.
