Nontraditional or alternative medicine is becoming an increasingly attractive approach for the treatment of various inflammatory disorders and cancers. Curcumin is the major constitute of turmoric powder extracted from the rhizomes of the plant Curcuma longa. Resveratrol is a phytoalexin present in grapes and a variety of medicinal plants. In this report, We investigated the effect of curcumin and resveratrol on regulatory protein of cell cycle, induction of apoptosis and MMP activity. Treatment with 75 M curcumin for 24 hrs produced morphological changing in HN-4 cells. Curcumin and resveratrol inhibited the cellular growth in HN-4 cells. Inhibition of cell growth was associated with down-regulation of cell cycle regulatory proteins. Curcumin-induced caspase-3 activation and Bax degradation were dose-dependent with a maximal effect at a concentration of 100 M. The elevated caspase-3 activity in curcumin treated HN-4 cells are correlated with down-regulation of survivin and cIAP1, but not cIAP2. Curcumin induced a dose-dependent increase of cytochrome c in the cytosol. Curcumin induced-apoptosis was mediated through the release of cytochrome c. In addition, curcumin-induced apoptosis was caused by the generation of reactive oxygen species, which was prevented by antioxidant N-acetyl-cysteine (NAC). Cotreatment with NAC markedly prevented cytochrome c release, Bax cleavage and cell death. Also resveratrol-induced apoptosis was preceded by down-regulation of the anti-apoptotic Bcl-2, cIAP1, and caspase-3 activity. However, resveratrol-induced apoptosis was not prevented by antioxidant NAC. In addition, HN-4 cells release basal levels of MMP2 when cultured in serum-free medium. Treatment of the cells with various concentrations of PMA for 24 hr induced the expression and secretion of latent MMP9 as determined by gelatin zymography. HN-4 cells were treated with various concentrations of curcumin and resveratrol in the presence of 75 nM PMA, and MMP2 and 9 activities were inhibited by curcumin and resveratrol. These findings have implications for developing curcumin-based anticancer and anti-inflammation therapies.
In South America, natural products with unknown drug effects are used as folk remedies and for preventive medicine. Among South American natural products, we directed our attention to Propolis, which have been known as medicinal plants, and examined the mechanisms by which these substances affect antioxidant activity, anti-tumor activity and immunoresponse. When the antioxidant activities of Propolis were examined by the DPPH and Rhoudan iron methods, since Propolis contains high levels of flavonoids, it is thought that flavonoids may be responsible for the antioxidant activity in this study. In the examination of immunoenhancement activity, we measured lymphocyte versus polymorphonuclear leukocyte ratios (L/P activity). The number of lymphocytes was significantly increased in groups treated with Proplolis. Specifically, slightly high levels of $IFN-{\gamma}$ were measured in mice bearing the S-180 carcinoma, after administration of Propolis. This strongly suggests that cellular immunity is especially activated by treatment with Propolis, because production of $IFN-{\alpha}$ is limited to the T cells and NK cells stimulated by mitogen and sensitized antigen. $TNF-{\alpha}$ shows a different extent and mechanism of action depending on the target cells. When $TNF-{\alpha}$ was measured in mice bearing the S-180 carcinoma, mice treated with Propolis showed slightly higher $TNF-{\alpha}$ levels as compared to the control group. This suggests that activated macrophages produce $TNF-{\alpha}$ in mice treated with Prapolis, since activated macrophages and lymphocytes are the source of most $TNF-{\alpha}$. When anti-tumor action was examined using two kinds of sarcoma (Ehrlich solid carcinoma and Sarcoma-180 carcinoma), tumor-suppressive ratios after treatment with Propolis was 29.1%. When Sarcoma-180 solid carcinoma was used, tumor-suppressive ratios were 62%. Thus, Propolis showed strong anti-tumor activity against two kinds of solid carcinoma. Taken altogether, this strongly suggests that Propolis enhances original functions of macrophages and NK cells, and as a result, secondarily enhances the immune reaction and suppresses tumor growth.

Glycyrrhiza inflata Batal, an important species of licorice, is one of the most widely used medicinal plants for over 4000 years. Glycyrrhiza plant species has been well known for its various therapeutic activities such as anti-inflammatory, anti-allergic, and anti-ulcer. The purpose of this study was to determine the effects of Glycyrrhiza inflata Batal ethanol extracts (GBE) on adipocyte and osteoblast differentiation. Mesenchymal C3H10T1/2 cells were treated with sub-cytotoxic doses of GBE, and its effects on adipocyte differentiation were assessed. We found that GBE dose-dependently increased lipid accumulation and also induced the expression of adipocyte markers, such as $PPAR{\gamma}$ and its target genes, aP2, and adiponectin, in C3H10T1/2 cells. Consistently, similar effects of GBE on lipid accumulation were also observed in preadipocyte 3T3-L1 cells that further supports the pro-adipogenic activities of GBE. We also investigated the effects of GBE on osteoblast differentiation of mesenchymal C3H10T1/2 cells. As a results, we found that GBE increased the activity of alkaline phosphatase in a dose-dependent manner and also promoted the expression of osteoblast markers, such as ALP and RUNX2, during osteoblast differentiation of C3H10T1/2 cells. Similar pro-osteogenic effects of GBE were also observed in preosteoblast MC3T3-E1 cells. Finally, our data show that a major bioactive compound found in Glycyrrhiza inflata Batal, licochalcone A (LA) but not glycyrrhizic acid (GA), can mediate the pro-adipogenic and pro-osteogenic effects of GBE. Taken together, this study provides data to show the possibility of GBE and its bioactive component LA as putative strategies for type 2 diabetes and bone diseases.
Effects of fungicides on the mycelial growth of Botrytis cinerea isolated from ginseng leaves were investigated by an agar dilution method. By using a agar dilution method, it was investigated the effect of fungicides, procymidone, carbendazim and the mixture with both of carbendazim and diethofencarb, on the mycelial growth of Botrytis cinerea isolates, which were isolated from infected leaves of ginseng in 2005 and 2006. With MIC (minimum inhibiton concentration) of procymidone against B. cinerea, pathogens were divided into two groups. While one showed the low MIC between 0.8 and $4.0{\mu}g/ml$, the other showed higher MIC above $20{\mu}g/ml$. In terms of the inhibition ratio of mycelial growth at the indicated concentration of procymidone, isolates of B. cinerea were divided into three groups; the sensitive, the intermediate resistant, and the resistant group. Each group was differentiated by $EC_{50}$; the sensitive group showed below $2.0{\mu}g/ml$, the intermediate resistant group between 2.0 to $5.0{\mu}g/ml$, and resistant group above $5.0{\mu}g/ml$. Compared with the ratio of resistant isolates of B. cinerea in 2005, the ratio in 2006 increased from 19.3% to 27.5%. Furthermore, the average $EC_{50}$ value of them increased from $10.0{\mu}g/ml$ in 2005 to $237.3{\mu}g/ml$ in 2006. The ratio of isolates showing the multiple resistance between procymidone and carbendazim was 40.2%, whereas the ratio was 4.0% showing the multiple resistance in the mixture.
This study is on perfume case that is one of a great number of ornaments which was designed by out ancestors. We had developed the tradition and the history of perfume case bag fan-weight etc. These have the same function as the present perfume. case. There were basket-shaped perfume cases which were the smellest one among the personal girdle ornaments in the silla era. The various patterned perfume case were made of gold metal coral platinum or green jadeite etc. In the single-crop trinkets a embroidered perfume bag with the gold and silver thread whose forms perfectly match their functions appeared during the Yi Dynasty. There was also a perfume bag which was one of the daily necessities. A precious "jul perfume" was carried by noble women. A fan-weight perfume bag was attached to the fan to emphasize the intrinsic beauty of utility and function. It is necessary to know the function of prefume case. As perfume case is weared on the clothes it was given more decorative effects as well as the function of medicinal amulet with a sweet smell. Therefore it is very important for us to study perfume case that has various function as an ornament. So The purpose of this study is to investigate the practical and decorative side of perfume case with the general examines of perfume finding how to practice use through our life. The results were as follows; 1. The first use of perfume is perfume through smoke which is for ceremony of religion It removes human body odor by degrees and spreads a sweet odor. Also the materials for making perfume of early age is aromatic plants which will be used flour-made flowers stems. As the materials for making perfume use is increasing today we can invent alcohol perfume today 2. Our country the custom of perfume-used is wide. Among them men's perfume-used was very special phenomenon. For example men were wearing perfume bag in the Silla era. Because perfume represented wealth and noble in those days. They shew off social position personality through perfume-used. 3. One of early religion ceremony article there was the perfume. And perfume case was means for containing perfume. Gradually the perfume case was used widly as increasing needs of perfume in human life. 4. In the middle period of 'Koryo' Dynasty perfume cases had a close relationship with clothes but after Mongolian has been attacked 'Koryo' there were changes in wearing clothes therefore the position of perfume cases were transfered to coat string that was the origin of decoration style that they began. That is to say the perfume case has been influenced the position of perfume case shapes with changing of fashion. 5. The perfume case has been made manifest various function as an ornament. In the practical side First medical-perfume in perfume case has been played an important role in first-aid medicine in critical condition. Second it was amulet for self protection. That is the shape pattern color materials perfume of the perfume case was represented the amuletive nature. Third it was used as substitute article of perfume. Modern women use liquid-perfume as our ancestors used perfume case bag or jul perfume As started above. Also In the decorative side the perfume case has a beautiful formative arts by itself as well as a close relationship with clothes. That well as a close relationship with clothes. That is when the perfume case is worn on the clothes costume is showed aesthetices. That is the materials shapes color pattern of the perfume case we can see the visual beauty also the materials colors embroidered pattern knots tassel that are used the perfume case are increased the decorative beauty of costume. Sixth the symbol in pattern of the pattern case is shown ancetor's wealth and rank health longevity immortality many-born-boy in those days. Today the perfume case is not used with changing of costume by degrees, Accordingly I hope that the result of this study is an influened in devlopment of the perfume case design with matching the modern fashion.

This study was designed to investigate variation of pinitol content in different parts of seventeen legume species including silk tree (Albizia julibrissin). D-pinitol has been demonstrated to exert insulin-like and anti-inflammatory effects. These legumes were collected from Gyeongsangbuk-Do in Korea. Significant difference in pinitol content was observed among 17 different legume species. However, it was the highest in sericea lespedeza (Lespedeza cuneata). The highest pinitol content was observed in leaf followed by stem, pod shell, seed and root among plant parts. Legume plants which had higher pinitol content in leaves were chinese pea shrub, bastard indigo, wild cowpea and sericea lespedeza, having 59.9 mg/g, 62.2 mg/g, 69.6 mg/g and 65.4 mg/g, respectively. Stem of astragali radix showed the highest pinitol content among all leagumes, which was 34.0 mg/g. In case of root, kudzuvine showed the highest pinitol content followed by licorice and chinese pea shrub, which were 24.6 mg/g, 16.9 mg/g, and 16.5 mg/g, respectively. However, in the case of pod shell and seed, only lablab purpureus and sericea lespedeza showed the highest pinitol content 52.5 mg/g (for pod shell) and 24.9 mg/g (for seed), respectively. Concluding, the sericea lespedeza showed the highest total pinitol content of whole plant followed by chinese redbud, chinese pea shrub, bastard indigo and silk tree. Considering the pinitol content and harvesting yield, sericea lespedeza can be used as a practical medicinal herb.

This study was conducted to clarify the effective application method, uptake, and translocation of germanium(Ge) in mungbean plants. The foliar application of liquid Ge at 7 mg/l during the flowering period, seeds containing 38.7, $14.1{\mu}g/kg$ of Ge, from the first and second harvesting. It had 2.5 and 2.3 times more Ge than the seeds raised by using granule Ge at 7 mg/kg with basal fertilization. The foliar application of Ge at 3.5, 7, 14 and 28 mg/l during the flowering period, yielded a relatively high record of seeds containing $14.9{\sim}77.8{\mu}g/kg$ and $6.9{\sim}26.7{\mu}g/kg$ of Ge, from the first and second harvesting. However, seeds from the first harvesting contained $2.2{\sim}4.1$ times more Ge than the seeds of from the second harvesting. On the other hand, seeds from first and second harvesting of the non-treatment group Ge contained 1.9 and $3.2{\mu}g/kg$, respectively. When the foliar application of Ge at 7 mg/l was conducted two or three times, the Ge content of the seeds in the first to third harvesting were all over $20{\mu}g/kg$. This indicates that a certain level of Ge can be accumulated. In seeds of mungbean containing $96{\mu}g/kg$ of Ge, cotyledon had $138{\mu}g/kg$ of Ge, which was 79% more than seed coat per unit weight. The growth and quantity of mungbean was not significantly different according to the formulation of Ge, the concentration and the frequency of foliar application of Ge used for in study.
Seven native and four introduced herbs namely $Thymus$$quinquecostatus$, $Chrysanthemum$$zawadskii$ var. $latilobum$, $Rosmarinus$$officinalis$, etc. were selected for analysis of the DPPH radical scavenging and anti-microbial activity of their extracts. These perennial herbs are classified as $Labiatae$ and $Compositae$ except for $Saururus$$chinensis$ and can be propagated through seedling and cuttage. These edible herbs are used as medicinal as well as ornamental plants. Their extract has electron donating ability which ranges from 69.7 to 78.7% for native herbs and 67.4 to 75.4% for introduced herbs. Native herbs have higher (3.54%) average DPPH radical scavenging than introduced herbs. In native herbs, maximum DPPH radical scavenging activity was observed in $Agastache$$rugosa$ (78.7%) followed by $Saururus$$chinensis$ while $Chamaemelum$$nobile$ showed highest activity among the introduced herbs. Many herbs viz. $Saururus$$chinensis$, $Chrysanthemum$$zawadskii$ var. $latilobum$ and $Solidago$$virga-aurea$ var. $gigantean$ showed excellent anti-microbial activity against gram positive $Enterococcus$$faecalis$, maximum (80.0%) by $Saururus$$chinensis$. Other herbs viz. $Solidago$$virga-aurea$ var. $gigantea$, $Chrysanthemum$$zawadskii$ var. $latilobum$, $Salvia$Salvia $plebeia$, $Chrysanthemum$$indicum$, $Rosmarinus$$officinalis$, $Chamaemelum$$nobile$ and $Lavandula$$stoechas$ showed anti-microbial activity against gram negative $Citrobacter$$freundii$. Especially, the inhibition of colony growth of $Citrobacter$$freundii$ was highest in the extract of $Chrysanthemum$$zawadskii$ var. $latilobum$, and $Chamaemelum$$nobile$.
This study was performed to develop natural spices and functional foods using Cheongung (Cnidium officinale) which is one of the Korean medicinal plants. The volatile flavor patterns of Cnidium officinale were detected by electronic nose with 6 metal oxide sensors, and the principal component analysis was carried out. The volatile flavor components of Cnidium officinale were isolated by simultaneous steam-distillation extraction with pentane and diethylether (1 : 1), and essential oils were analyzed by capillary GC and GC/MS. The free radical scavenging activity of ethanol and methanol extracts from Cnidium officinale was measured by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and compared with ${\alpha}-tocopherol$ as reference. The principal component analysis showed the difference of principal components between fresh and drying samples. Eighty-five volatile flavor components (643.64 ppm) from fresh Cnidium officinale were identified and the major components were butyl phthalide, sabinene, neocnidilide. Sixty-four volatile flavor components (218.15 ppm) from hot air dried one were identified and the major components were butyl phthalide, sabinene, 3-N-butyl phthalide. And 73 volatile flavor components (784.15 ppm) from freeze dried one were identified and the major components were butyl phthalide, sabinene, ${\beta}-selinene$. The free radical scavenging activity of methanol cold extract (500 ppm) of freeze dried Cnidium officinale was higher than other samples. And methanol and ethanol cold extracts (above 250 ppm) of freeze dried sample were higher than ${\alpha}-tocopherol$$25\;{\mu}M$ (22.34%).

In a continuing screening of selected medicinal plants native to South Korea, the antioxidant and pancreatic lipase inhibitory activities of an aqueous methanolic extract from the heartwood of Aquilaria agallocha were investigated. Eighty percent of the methanolic extract of A. agallocha was further divided into $CH_2Cl_2$, EtOAc and n-BuOH in order to yield four solvent-soluble portions, namely $CH_2Cl_2$-soluble, EtOAc-soluble, n-BuOH-soluble and $H_2O$ residue. The antioxidant properties were evaluated by employing radical scavenging assays using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) ($ABTS^+$) radicals, while the anti-obesity efficacy of A. agallocha extracts and solvent-soluble portions were tested by porcine pancreatic lipase assay. All tested samples showed dose-dependent radical scavenging and pancreatic lipase inhibitory activities. Among the tested extracts and solvent-soluble portions, the $CH_2Cl_2$-soluble portion showed much higher radical scavenging activity and pancreatic lipase inhibitory properties when compared with other solvent-soluble portions. This result suggested that there was a significant relationship between the total phenolic content and biological efficacies, and A. agallocha extract might be considered as a new potential source of natural antioxidants and as a pancreatic lipase inhibitory source. A more systematic investigation of this biomass will be performed for further investigation of activity against antioxidative and anti-obesity effects.
