  • The purpose of this study was investigated hypoglycemic effects of fermented red ginseng extracts. We prepared non-fermented red ginseng extracts(R), fermented with Lactobacillus plantarum(RL) extracts, Saccharomycescerevisiae(RS) extracts, and L. plantarum mixed S. cerevisiae(RLS) extracts, examined composition of ginsenosides, SOD-like activity, and $\alpha$-glucosidase inhibitory activity. Ginsenoside Re was highest contents in all extracts, second was ginsenoside Rc and then ginsenoside Rb1. Concentration of these ginsenoside was showed higher in RS than in other extracts. SOD-like activity and $\alpha$-glucosidase inhibitory activity were shown higher in fermented red ginseng extracts than non fermented extracts. And activities of mixed fermentation extracts(RLS) higher than single fermentation extracts(RL, RS). Effects of blood glucose level, serum lipid profile and metabolic variables were evaluated in streptozotocin(STZ) induced diabetic rat. Experimental group was divided into 7 groups: normal control group(hereafter NC group), diabetes control group(DC group), positive control group treated with 50 mg/kg body weight of acarbose(PC group), treated with 300 mg/kg body weight of R, RL, RS and RLS extracts groups, respectively. Blood glucose level of DC group was maintained high level in all experimental period, but treated with red ginseng extracts groups was reduced the glucose level by R group 18.00%, RL group 28.07%, RS group 29.03%, RLS group 42.42%, respectively. The concentration of total cholesterol and triglyceride of fermented red ginseng extracts treated groups (RL, RS, RLS) was lower than non- fermented extracts group(R) DC and PC groups. The activity of ALT, AST in RLS treated groups were lower than other groups.

  • 고지방 식이 유도 비만 흰쥐에 Monascus purpureus균주로 발효시킨 참당귀 추출물을 식이에 첨가하였을 때 나타나는 체중 및 내장지방의 감소, 혈중 및 조직 내 중성지질 및 과산화지질 수준에 미치는 영향을 평가하였다. FAG섭취로 인해 체중증가 및 내장지방 축적 비율을 효과적으로 낮추었으며, 간 기능 지표로 활용되는 혈중 AST, ALT, LDH 및 ALP 활성 변화는 정상 수치와 비슷한 수준으로 감소되었다. FAG를 섭취함으로서 혈중 중성지질 농도가 정상 수준으로 감소하였으며, 혈중 leptin 호르몬 함량 또한 정상 수치와 비슷한 수준으로 증가하였다. 고지방 식이 섭취로 인한 각 조직 과 혈청 내 과산화지질(TBARS)을 측정한 결과 고지방 식이만 섭취한 C군에 비해 각 실험군에서 유의적으로 감소하였으며, 특히 FAG10군에서 가장 낮은 함량을 나타내었다. Hematoxylin과 eosin 염색 및 Oil red O 염색을 통해 FAG를 섭취함에 따라 간장 내 지질침착도의 감소를 확인였으며, 부고환 주변 지방 조직의 hematoxylin과 eosin 염색으로 지방세포의 크기가 감소되었음을 확인하였다.

  • To investigate the effect of GyeongshinhaeGihwan 1(GGT1) frequently used as an anti-obesity herbal medicine in oriental medicine on the expression of obesity-related genes, we measured the changes in mRNA levels of these genes by GGT1 in human growth hormone transgenic (hGHTg) obese female rats, and these effects by GGT1 were compared with those of reductil (RD), an anti-obesity drug approved by FDA. Rats received once daily oral administrations of autoclaved water, RD, or GGT1 for 8 weeks. At the end of study, rats were sacrificed and tissues were harvested. Total RNA from adipose tissue, liver and kidney was prepared and the mRNA levels for LPL (lipoprotein lipase), $PPAR{\gamma}$ (peroxisome proliferator activated receptor-gamma), $PPAR{\delta}$ (peroxisome proliferator activated receptor-delta), leptin, $TNF{\alpha}$ (tumor necrosis factor-alpha), and internal standard G3PDH (glyceraldehyde-3-phosphate dehydrogenase) were analyzed by RT-PCR. Compared with control group, $PPAR{\gamma}$ mRNA levels of liver and kidney were decreased in both RD and GGT1 groups, and the effects were more prominent in GGT1 group than in RD group, suggesting that GGT1 is effective in the inhibition of lipid storage by decreasing the $PPAR{\gamma}$ expression. $PPAR{\delta}$ mRNA levels of adipose tissue were increased by RD and GGT1 compared with DW, and the magnitude of increase were higher in GGT1 group than in RD group, indicating that GGT1 stimulates fatty acid oxidation and energy metabolism by activating $PPAR{\delta}$ expression. GGT1 group had higher concentrations of serum leptin, a well-known inhibitor of appetite, than control and RD groups. However, The mRNA levels of leptin, LPL, and $TNF{\alpha}$ were not changed by GGT1. These results indicate that GGT1 can prevent obesity in hGHTg obese female rats by down-regulating and up-regulating the mRNA expression of $PPAR{\gamma}$ and $PPAR{\delta}$, respectively, and that this anti-obesity effects were more pronounced in GGT1 group compared with RD group. In addition, GGT1 seems to inhibit obesity by increasing the circulating leptin levels.

  • This study was designed to elucidate whether combination with Korean red ginseng and Morus alba L. (MPM), traditional treatment for diabetes, ameliorates on high fructose-induced steatohepatitis and vascular inflammation. Animals were divided into four groups; Control receiving tap water, fructose-fed, rosiglitazone-treated fructose-fed rats, and MPM-treated fructose-fed rats both receiving supplemented with 60% fructose (n=10). The MPM or rosiglitazone groups initially received a high-fructose diet alone for 8 weeks, with supplementation with MPM or rosiglitazone, peroxisome proliferators-activated receptor gamma ($PPAR{\gamma}$) agonist, occurring during the final 6 weeks. Treatment with MPM significantly prevented the increase in c-reactive protein (CRP) levels in the high fructose group. MPM suppressed high fructose diet-induced vascular inflammation marker expression such as intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin. MPM also reduced intima/media thickness of thoracic aorta. Histologic observation and oil red O staining demonstrated hepatic tissue damage and lipid accumulation were severe in high fructose group. Treatment with MPM ameliorated hepatic tissue morphology with minimized steatosis. In addition, MPM attenuated hepatitis by inhibition of monocyte chemoattractant protein-1 (MCP-1) expression. MPM-fed group showed lower serum GOT and GPT levels comparing with high fructose group. MPM and rosiglitazone (positive control) significantly decreased the size of epididymal adipocytes. Taken together, the administration of MPM inhibited high fructose-induced steatohepatitis and vascular inflammation. These results suggested that MPM is useful in the prevention or treatment of metabolic syndrome-related disorders such as fatty acid metabolism and vascular homeostasis.

  • Objective: The aim of this study was to compare overfeeding performance, fatty acid composition, blood chemistry, enzymes and genes expression overfed Xupu and Landes geese. Methods: Sixty male Xupu geese (80 d) and Landes geese (80 d) were selected. After a period of one-week of pre-overfeeding, Xupu and Landes geese were overfed three meals of 550 and 350 g/d, respectively, of a high-carbohydrate diet in the first week of the overfeeding period. The next week, geese were given four meals of 1,200 and 850 g/d, respectively, over 8 to 14 d. Finally, geese were given five meals of 1,600 and 1,350 g/d, respectively, for the last two weeks. Results: After overfeeding for 28 d: Compared with Landes geese, Xupu geese liver weight and liver-to-body weight ratio decreased (p<0.05), while final weight, slaughter weight, total weight gain, abdominal fat weight, and feed-to-liver weight ratio increased (p<0.05). The levels of elaidic acid (C18:1t9), oleic acid (C18:1n-9), eicosenoic acid, and arachidonic acid in the liver of Xupu geese significantly increased (p<0.05), and the levels of myristic acid and stearic acid significantly decreased (p<0.05), while methyleicosanoate acid significantly increased (p<0.05). Xupu geese had higher plasma concentrations of triglyceride and very low density lipoprotein cholesterol (p<0.05), and decreased activities of alanine aminotransferase, aspartate aminotransferase, and lipase (LPS) (p<0.05). Landes geese had higher LPS activity (p<0.05), but lower cholinesterase activity (p<0.05) when compared with Xupu geese. The mRNA expression levels of fatty acid dehydrogenase (FADS) gene, elongase of long-chain fatty acid 1 (ELOVL1) gene, ELOVL5, and acyl-Co A: cholesterol acyltransferase 2 (ACAT2) gene were significantly upregulated (p<0.05) in Landes goose when compared with Xupu geese. Conclusion: This study demonstrates that the liver production performance of Landes geese was better than that of Xupu geese to some extent, which may be closely related to LPS activity, as well as the expression of FADS, ELOVL1, ELOVL5, and ACAT2.

  • Backgrounds : As obesity prevails as an epidemic. diet programs including low-calorie diets are developed continuously. It is generally believed that a low-calorie diet is commonly followed by resting metabolic rate decrease and ultimate weight regain. Ephedra and Evodia are known to have sympathomimetic and anti-obesity effect. Objectives : This study was a prospective, double-blinded, randomized md placebo-controlled clinical trial to evaluate the effects of Ephedra sinica and Evodia rutaecarpa on resting metabolic rate (RMR), weight, body composition, and short-term safety in obese women on low-calorie diet. Methods : 125 otherwise healthy obese women (body mass Index ${\geq}\;25kg/m^2$) were recruited and randomly assigned to three groups: Ephedra group (n=41), Evodia group (n =45), and placebo group (n=39). Subjects were administered Ephedra extract in capsules (pseudo-ephedrine 31.52mg) or Evodia extract in capsules (evodiamine 6.75mg, rutaecarpine 0.66mg) or placebo capsules as well as participating in a low-calorie diet for 8 weeks, Resting metabolic rate and body composition were measured at baseline,4 and 8 weeks. Basic serum exams were performed to evaluate the short-term safety of the herbs and changes of lipid variables. Results : All three groups showed significant BMI decreases probably due to low-calorie diet. Among them, the Ephedra group manifested most prominent BMI-reducing effect and towered total cholesterol and triglycerides significantly. The RMR was not changed during the 8-week diet in all groups. No significant difference among the groups was found in RMR, either. Stbject with higher RMR than the mean at the baseline showed a tendency to keep their RMR more stable during the diet program. Conclusions : Ephedra with a low-calorie diet was effective in reducing BMI. RMR change was not compensated by herbal medicines. RMR change seemed to be affected rather by constitution and body composition than medicine. Ephedra and Evodia were proven to be safe for sort-term use in herbal form. Especially, Ephedra was effective in lowering total cholesterol and triglycerides during the 8 weeks.

  • In this study, we examined the effects of dietary 1,3-diacylglycerol (DG) compared to conventional triacylglycerol (TG) oil on the postprandial response of total and chylomicron TG, glucose, insulin, and free fatty acid (FFA). This study was conducted using a cross-over design. Ninety subjects participated in the high-fat meal tolerance test where they were randomly assigned to consume two experimental sandwiches containing mayonnaise with TG or DG oil with a seven-day interval. Blood samples were collected before ingestion and at 2, 3, 4 and 6 hr time point after ingestion and analyzed for total and chylomicron TG, glucose, insulin, FFA and phospholipid fatty acid composition. Both TG and DG ingestion had similar effects on postprandial TG response, but a different response from chylomicron TG. Compared with the TG group, TG levels were significantly lower only at 6 hr time point in the DG group. On the other hand, chylomicron TG rose steeply at 2 hr time point and decreased faster in this group. Also, the adjusted value to fasting levels was the same as the unadjusted level. Fasting levels and net differences in insulin were significantly lower at 3 hr time point where chylomicron TG levels were significantly lower in the DG group. But those of glucose and FFA in the TG and DG groups did not differ significantly. Fasting and postprandial levels of fatty acid composition in serum phospholipids in the two groups did not differ significantly. In conclusion, this study indicated that one could reduce the magnitude of postprandial lipemia without influencing glucose metabolism by consumning DG oil as a substitute for TG oil. Based on the correlation of coronary artery disease and postprandial lipemia, dietary DG ingestion might have a beneficial effect in treating such a disease. Further studies are required to clarify the long-tenn effects of dietary DG on blood lipid levels in humans.

  • 본 실험에서는 사람의 본태성 고혈압과 가장 유사 한 증상을 나타내는 SHR을 이용하여 고혈압의 악성기에 해당하는 6개월간의 장기간 동안 생마늘과 익힌 마늘 첨가식이를 급여함으로써 마늘의 열처리가 혈청 지질과 혈액 응고에 미치는 효과를 비교 관찰하였다. 실험 결과를 요약하면 다음과 같다. 식이 섭취량은 익힌 마늘 3% 첨가군이 다소 낮았으며, 체중 증가량 및 식이 효율은 마늘 첨가군과 대조군간이 차이는 없었다. 총 콜레스테롤 수준은 마늘 첨가군이 대조군에 비해 현저히 저하되었으며, 특히 익힌 마늘군이 생마늘 군 보다 낮게 나타났다. 중성 지질 수준은 마늘 첨가군 들이 대조군에 비해 낮았다. 혈장 prothrombin time은 마늘 첨가군들이 대조군 보다 길었으며, 마늘 열처리에 따른 차이는 없었다. Fibrinogen 농도는 익힌 마늘군이 대조군이나 생마늘군 보다 낮았다. Fibrinogen과 pro- thrombin time은 유의한 부의 상관관계를 나타내었다. 이상을 종합하여 살펴보면, 익힌 마늘 3%와 생마늘 3% 첨가군 모두 체중이나 식이 섭취량 및 식이 효율에서 대조군과 큰 차이가 나타나지 않은 것으로 보아 일상 식이 섭취 수준으로서 섭취할 수 있는 농도로 여겨진 다. 열처리 효과를 비교해 보면, 익힌 마늘의 생리 효과가 생마늘에 비해 낮다고 보고된 타 연구 결과와는 달리 , 본 실험에서는 익힌 마늘과 생마늘의 효과가 유사 한 것으로 나타났다.

  • Objectives : This study was performed to investigate the effects of $LR_3$ and $SP_6$ acupuncture on renal damage in streptozotocin(STZ)-induced diabetic mice. Methods : ICR male mice were stabilized for a week and divided into four groups: a normal mice group(N), no-acupuncture diabetic mice group(Control), $LR_3$ acupuncture diabetic mice group($LR_3$), and $SP_6$ acupuncture diabetic mice group($SP_6$). Diabetes was experimentally induced by intraperitoneal injection of STZ(150 mg/kg) in citrate buffer(pH 4.5). For two weeks, $LR_3$ and $SP_6$ acupunctures were administered bilaterally at each point once a day. After two weeks, the animals' weight was measured and they underwent a laparotomy. Serum glucose and blood urea nitrogen(BUN) were measured from the blood taken from the heart. We measured glucose, reactive oxygen species(ROS), peroxynitrite($ONOO^-$) and thiobarbituric acid reactive substances(TBARS) in the kidney and compared expression levels of superoxide dismutases(SOD), glutathione peroxidase(GPx), nuclear factor-kappa B(NF-${\kappa}B$), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase(iNOS) and Interleukin-1 beta(IL-$1{\beta}$). Results : BUN significantly decreased in $LR_3$, $SP_6$ compared to the control group. $LR_3$ showed significantly decreased glucose compared to the control group. $LR_3$, $SP_6$ significantly decreased in ROS and $ONOO^-$ compared to the control group. $LR_3$ significantly decreased in TBARS compared to the control group. $SP_6$ significantly increased in expressions of SOD-1, catalase, and GPx compared to the control group. $LR_3$, $SP_6$ significantly decreased in COX-2 compared to the control group. $SP_6$ significantly decreased in IL-$1{\beta}$ compared to the control group. Conclusions : This study suggests that $LR_3$ acupuncture may be effective in controlling glucose and lipid peroxidation and that $SP_6$ acupuncture may have anti-oxidative and anti-inflammatory effects on renal damage in STZ-induced diabetic mice.
