  • Chlorogenic acid, formed of an ester of caffeic acid and quinic acid, which is naturally abundant in many plant species, was used as a model O-dihydoxy phenolic compound. In the previous study, we have reported that the isolated constituent from Apocynum venetum leaves has an inhibitory effect on $Cu^{2+}$-induced oxidative modification of low-density lipoprotein (LDL). Among them, chlorogenic acid showed the most potent anti-LDL oxidative activity than other compounds. For the reason, we investigated the inhibitory effect of the chlorogenic acid on $Cu^{2+}$-induced oxidative modification of LDL, monitored a lag time in the conjugated-diene formation and TBARS formation, and measured TNBS free amino acid group, and form cell formation in vitro system. The TBARS- and diene- formation were strongly inhibited by chlorogenic acid ($0{\sim}100\;{\mu}g/ml$) with dose dependent manner. On the other hand, TNBS reactive lysine amino groups on LDL oxidation were protected by chlorogenic acid- treated cell group. Therefore, chlorogenic acid inhibited to cholesterol accumulation in the isolated peritoneal macrophage.

  • The hypoglycemic effects of 2 mushrooms, Pleurotus ostreatus and Lentinus edodes, on streptozotocin(STZ) induced diabetic rats were investigated in this study . Diabets mellitus was induced in male Sprague-Dawley rats by the injection of STZinto the tail vein at a dose of 45mg/kg. Sprague-Dawley male rats(200-250g) were assigned to one control and three STZ-diabetic groups. Diabetic groups were assigned to STZ-control, pleurotus ostreatus and Lenitinus edodes groups. All groups were fed a AIN 76 diet. The two experimental groups were fed with each protein-bound polysaccharide(150mg/kg BW) for 14 days and with carboxymethyl cellulose for STZ-control group. The body weight gain was monitored and the blood levels of glucose and cholesterol were measured . Levels of protein triglyceride, and free fatty acid in plasma were analysed. Serum aminotransferase activity as also measured. The body weight gain was lower in the all diabetic groups than in the of normal group. The weight of spleen was reduced by adminstration of the Lentinus edodes protein-bound polysaccharides. The result suggest that orally administered Lentinus edodes protein-bound polysaccharides exhibited hypoglycemic effect in STZ -induced diabetic rats and that these protein-bound polysaccharides may be useful for the management of diabetes mellitus.

  • The superoxide anion radical$(O_2)$ poses a threat to macromocules and cell organelles of the living cells. This toxicity damage to all groups of proteins results in loss of enzyme function concerned with metabolism and ion transport, and peroxidation of unsaturated fatty acids and cholesterol results in a change of permeability characteristics of the membrane, and oxidative of nucleic acids results in genomic damage and thereby cause mutation, potential carcinogenesis and somatic damage that produce cellular aging Superoxide dismutase(SOD) has received substantial attention as a potential therapeutic agent. It has been investigated as a possible agent for the prevention of ontogenesis, the reduction of cytotoxic effect of anticancer drugs, and protection against damage in ischemic tissue. It is suggest that $O_2$ is concerned with cellular aging, thereafter we need to investigate herb that activated to SOD.

  • Obesity can be defined as a metabolic disease due to a increased state of fat tissue caused by an imbalance of calorie intake and use. To define genes that affected by different nutrient, we study gene expression from mice which were fed different nutrient. Epididymal and retro-peritineal adipose tissue were increase in high fat diet feeding mice compared with control, but liver and spleen were not. In serum, total cholesterol were differently increase in high fat diet feeding mice but total triglyceride and free fatty acid were not. That was maybe result of energy balance regulation in vivo system. aP2, PPART2 and FAS genes that were increased during adipogenesis were inclosed in high fat diet fed mice compared with control. In microarray assay, 1.4% of total genes were affected in epididymal adipose tissue by different nutrient. 1.1% of total genes were decreased down 0.5 fold and 0.3% were increased over 2 fold. These results indicated that many genes are affected in adipose tissue by nutrient.

  • Cynanchi wilfordii Radix roots have been utilized as traditional medicine for variety of diseases including diabetes mellitus, aging progression and scavenging free radicals, enhancing immunity, reducing high serum cholesterol, and anti-tumor activity. However, the mechanisms underlying this effect remain poorly understood. The principal objective of this study was to determine the effect of cynandione A on osteoclast cells. Thus, we was isolated cynandione A from Cynanchi wilfordii Radix roots and evaluated the effect of cynandione A on receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation. We found that cynandione A significantly inhibited osteoclast differentiation stimulated-RANKL in RAW 264.7 cells. Cynandione A conspicuously inhibited the mRNA and protein expression of matrix metallopeptidase 9 (MMP-9), tartrate-resistant acid phosphatase (TRAP) in cynandione A treated with RANKL. Taken together, our results demonstrated that Cynanchi Wilfordii Radix may be useful treatment option of bone-related disease such as osteoporosis leads to fracture of bone and rheumatoid arthritis.

  • Background and Purpose : Chunghyul-dan has been widely used in the Department of Cardiovascular & Neurologic Diseases, Kyung Hee Oriental Medical Center to prevent stroke by lowering serum cholesterol level. Previous experimental and clinical studies revealed that Chunghyul-dan had therapeutic effects on hyperlipidemia by inhibiting HMG-CoA reductase and pancreatic lipase. It was also reported that Chunghyul-dan showed an anti-oxidation effect by scavenging free radicals and inhibiting nitric oxide synthesis. Therefore, we examined the safety of Chunghyul-dan on all subjects who had been treated with it. Methods : We performed a retrospective study by reviewing the medical records of those who had been administrated Chunghyul-dan at Kyung Hee Oriental Medical Center from February 8,2001 to December 31,2002. The subjects' general characteristics (gender, age, medical history, and present illness), recorded adverse effects, and the results of laboratory findings were obtained and analyzed to assess the clinical safety of Chunghyul-dan. Results : Six hundred fifty six subjects were treated with Chunghyul-dan. Clinical adverse effects appeared in 13 subjects, the major symptom being indigestion (8 subjects). The apparent frequency of adverse effects was much lower than that in previous reports on the safety of certain medications. On investigation of laboratory findings, we could not find any hepatic or renal toxicity. Conclusion : We suggest that our results contribute towards confirming the safety of Chunghyul-dan by offering clinical evidence.

  • Total saponin, protopanaxadiol-saponin and protopanaxatriol-saponin were isolated and purified from the side roots of red ginseng. After we administered them orally into rats during 5 weeks, we observed their effects on lipid and glucose content in rat serum. The change in body weight of protopanaxatriol- saponin treated group was slightly larger than those of other groups. Total lipid content in total saponin treated group showed an increase of about 20 % over that in control group. However, protopanaxadiol-saponin and protopanaxatriol- saponin treated groups showed no change. While triglyceride content in total saponin treated group decreased 29oyo compared to it s content in control group, its content in protopanaxatriol-saponin treated group increased 45%. Three saponin treated groups showed lower value than control group in total ant free cholesterol levels. While glucose content in total saponin treated group decreased slightly, that in Protopanaxadiol-saponin treated group decreased slightly compared to that in control group. And protopanaxatriol- saponin trented group showed the significant decrease of 25%. From these results, it is supposed that total saponin accelerates the conversion of lipid into glucose and that protopanaxatriol- saponin accelerates the conversion of glucose into lipid.
