Objectives : ROS are involved in a wide spectrum of diseases including chronic inflammation and cancer. S.chinensis Baill, a perennial herb commonly called Chinese lizard's tail or Sam-baek-cho in Korea, is used for the treatment of edema and inflammatory diseases in the Oriental folk medicine. In this study, we investigated the antioxidant activities and anti-inflammatory effects of the two extracts, water(WE) and ethyl acetate(EAE) from S.chinensis Baill. Methods : Anti-oxidant activity was evaluated using Fe2+ chelating and hydroxyl radical scavenging assay. DNA cleavage assay, and western blot and immunostaining for phospho-p65 were performed to evaluate anti-oxidative effect. Anti-inflammatory effect was performed using NO generation assay and western blot in LPS-stimulated RAW264.7 cell. Results : In Fe2+ chelating activity and hydroxyl radical scavenging activity, WE showed more strong scavenging activity for hydroxyl radical than EAE. WE scavenged hydroxyl radical by 12% at 3.2
, 21% at 16
, 32% at 80
, 66% at 400
and 82% at 2000
, respectively. In addition, WE showed more strong chelating activity than EAE. WE chelated Fe2+ ion by 1.1% at 3.2
, 8.2% at 16
, 26.3% at 80
, 72% at 400
and 89% at 2000
, respectively. Also, WE inhibited oxidative damage via its anti-oxidant activity. In anti-inflammatory effect, EAE inhibited NO production and iNOS expression. In addition EAE suppressed the NF-
and MAPK signaling pathway in LPS-stimulated RAW 264.7 cells. Conclusions : Together, these data indicate that S. chinensis Baill, shows anti-oxidant activity and anti-inflammatory effect.

Objectives : Reactive oxygen species (ROS) have been associated with pathogenic processes including carcinogenesis through direct effect on DNA directly and by acting as a tumor promoter. Therefore, it has been regarded that ROS may be a major target for cancer prevention. The root of Paeonia lactiflora pall (PL), a traditional Chinese herb, has been a component of effective prescriptions for treatment of liver disease. Also, there are some reports about the antioxidant activities of the extracts from PL. However, little has been known about the effects of PL against oxidative damage. This work aimed to elucidate the anti-oxidant effects of Paeonia lactiflora pall (PL) in the non-cellular system and cellular system. Methods : Antioxidant activities of PL were evaluated by hydroxyl radical scavenging assay and
chelating assay. Anti-oxidative effect of PL was evaluated by
-174 RF I plasmid DNA cleavage assay in non-cellular system. In addition, DNA migration assay, expression level of phospho-H2AX, MTT assay and lipid peroxidation assay were performed for evaluate the anti-oxidative effect of PL in cellular system. Results : PL had a dose-dependent hydroxyl radical scavenging and
chelating capacity. In addition, PL inhibited oxidative DNA and cell damage induced by hydroxyl radical in non-cellular system and cellular system. Conclusion : Taken together, P. lactiflora pall may be possible for the application to a potential drug for treating the oxidative diseases such as cancer.

Objective : Lonicera japonica THUNB. a traditional herbal medicine, has been commonly used anti-inflammatory disease. It has been very complicated with respect to its sources on the market. The significant selection of medicine depends on its origin. However, it is difficult to discrimination criteria for confirming L. japonica authenticity using the senses. This study was performed to determine the discriminant analysis of L. japonica and L. confusa. Methods : The identification of L. japonica and L. confusa were performed by the classification and identification committee of the national center for standardization of herbal medicines. And we examined its differences using HPLC and genetic marker analysis. Results : The analytical pattern of High Performance Liquid Chromatography was determined from the corresponding peak curves ((E)-aldosecologanin, chlorogenic acid, luteolin 7-O-glucoside, sweroside). For L. japonica, additional unknown peaks were detected at 13.8 min, 20.6 min, and 36.9 min. And, we developed genetic marker using the the tRNA-Leu gene, trnL-trnF intergenic spacer and tRNA-Phe region of chloroplast DNA. By the method, 164 bp PCR product amplified from L. confusa was distinguished into L. japonica and L. confusa efficiently. Conclusion : Base on these results, two techniques provide effective approaches to distinguish L. japonica from L. confusa.

DOI : 10.6116/kjh.2012.27.6.23
Objectives : Samhwangsashim-tang(SHSST), a mixture of Rhei radix et rhizoma, Scutellariae radix, and Coptidis rhizoma, has been regarded as being able to treat bleeding, gastric discomfort, dry mouth, insomnia and purpura due to Blood Heat. Currently, this herbal formula is applied to gastritis, gastric ulcer, hypertension, atherosclerosis or other types of vascular inflammatory disorders. Methods : We extracted this herbal mixture with 30% ethanol and examined for its effects on systemic inflammatory responses and in vitro macrophage activity. Mice were orally given to SHSST for 7 days and then lipopolysaccharide(LPS) was intraperitoneally injected. Tumor necrosis factor-
) levels in serum were measured 1 h after LPS challenge. Peritoneal macrophages were isolated from thioglycollate-injected mice and used for in vitro cellular activity. Cell death was measured using the MTT method and annexin V/propidium iodide staining. LPS-stimulated signaling molecules necessary for TNF-
expression were determined by Western blotting. Results : Oral administration of SHSST for 7 days resulted in a significant reduction in LPS-stimulated TNF-
release into serum. In vitro treatment of SHSST was cytotoxic in a concentration-dependent manner. However, SHSST caused a concentration-dependent reduction in necrosis and increase in apoptosis in mouse peritoneal macrophages. SHSST inhibited the activation of NF-
, p38 and JNK signaling molecules in response to LPS. Conclusion : Taken together, our results demonstrated that SHSST was effective in lowering LPS-stimulated TNF-
serum levels, possibly through its modulation of NF-
, p38 and JNK in macrophages.

Objectives : To observe the effect of 4 kinds of Korean medicine and complex extracts on the anti-stress of chronic mild stress Rat model, so as to find out the machanism of its pharmacological effects. Methods : 64 healthy SD Rats were randomly divided into 8 groups. Model Design by chronic stress(CSM), and carried out the forced swimming test. We investigated the body weight, feed and water intake, feed conversion ratio and measured parameters to changes in swimming time, immobility time, 2 and 24 hours of feces, corticosterone hormone and blood glucose level. Results : In this experiments, body weight gain and feed intake were higher in all korean medicinal herb group. Swimming time were increased by Zizyphus jujuba and Gagamsanzointang(SZT) groups and immobility time was significantly lower by Zizyphus jujuba and Fluoxetine(FLX) groups. The result of corticosterone hormone level were significantly lower in Fluoxetine(FLX) and Gagamsanzointang(SZT) but blood glucose was not significantly difference. In 2 hours after fecal frequency result were significantly lower in Zizyphus jujuba group. but SZT group were increased. This result caused by acute stress but 24 hours of feces were restored to normal. Conclusions : 5 kind of Korean Medicinal Herbs extracts has good anti-stress effects, and also to clear the circulatory system and regulate blood glucose and improve bowel function. We suggest that use a single Korean medicine rather than the combination to relieve stress.

Objectives : Angelica Gigantis Radix is prescribed as the root of different Angelica species on the pharmacopoeia in Korea, Japan and China. Chemical components and their biological activities were also different according to their species. A study for the development of simple method to compare Angelica roots was needed. In order to classify them, the methods such as DNA sequencing analysis and taste sensor were applied to three Angelica species like Angelica gigas, Angelica acutiloba and Angelica sinensis. Methods : PCR amplification of intergenic transcribed spacer (ITS) region was performed using ITS1 and ITS4 primer from nine Angelica roots, and then nucleotide sequence was determined. Taste pattern of samples were measured using the taste-sensing system SA402B equipped with a sensing unit, which consists of artificial lipid membrane sensor probes of anionic bitterness, astringency, saltiness, umami, and cationic bitterness (C00, AE1, CT0, AAE, and AN0, respectively). Results : As a result of comparing the similarity of the ITS region sequences, A. sinensis was discriminated from the others (A. gigas and A. acutiloba). Equally this genetic result, A. gigas and A. acutiloba showed similar taste pattern as compared to A. sinensis. Sourness, bitterness, aftertaste of bitterness, astringency, and aftertaste of astringency of A. sinensis were significantly high as compared with A. gigas and A. acutiloba. In contrast, richness was significantly low. Conclusions : These taste pattern can be used as a way of comparison of Angelica species and this technic could be applied to establish a taste pattern marker for standardization of herbs in various purposes.

DOI : 10.6116/kjh.2012.27.6.43
Objectives : This study was investigated to determine the contents of pesticide residues and sulfur dioxide residues in commercial herbal medicines in Korea. Methods : Chromatographic test was performed on 100 samples consisted with 10 kinds of medicinal plants including improted and domestic products. To establish 19 pesticide residues (DDE, DDD, DDT, Dieldrin, Methoxychlor, BHC isomers, Aldrin, Endosulfan isomers, Endrin, Captan, Procymidone, Chlorpyrifos and Imidacloprid) in commercial herbal medicines, chromatographic equipments were used with the gas chromatography-mass detector and gas chromatography-electron capture detector for qualitative analysis. The imidacloprid analysis was performed by high performance liquid chromatograpgy-ultraviolet detector at 270 nm UV wavelength. The contents of sulfur dioxides were analyzed by modified Monnier-Williams method. All methods were based on notification procedure of Korea Food & Drug Administration (KFDA). Results : The residual pesticides were not founded in improted and domestic samples. Among 100 samples, the residues of sulfur dioxide in 73 samples were not detected and 25 samples showed contents in the range of 0~21.90 mg/kg. The excess samples of MRLs were 2 samples (30 mg/kg to medicinal herbs), Asiasari Radix et Rhizoma (Imported product) and the average amount of sulfur dioxide in 2 unsuitable samples were 14.83 mg/kg. These samples were found to transgress KFDA regulatory guidance of residual sulfur dioxide. Conclusion : These results are able to use as basic data to improve the reliability and value of commercial medicinal herbs.

DOI : 10.6116/kjh.2012.27.6.49
Objective : We recently reported that OMC-2010 has an immuno-modulatory effects via inhibiting tumor necrosis factor (TNF)-
and interleukin (IL)-5. However, we did not find out which constituents play an important role in immuno-modulatory effect of OMC-2010. Thus, this study was performed to estimate the effects of constituents of OMC-2010 on cytokine production in mouse spleen cells, then ultimately reach to find out effective constituents regulating splenic cytokine production. Methods : Mouse spleen cells were pre-treated with water and ethanol extract of constituents of OMC-2010 such as Rehmannia glutinosa (RG), Pinellia ternata (PT), Citrus unshiu Markovich (CUM), Glycyrrhiza uralensis (GU), Platycodon grandiflorum (PG), Schisandra chinensis (SC). After 1 h, the cells were stimulated with lipopolysaccharide (LPS, 1
) for 48 h. Then the cells were harvested for real-time reverse transcription polymerase chain reaction to detect cytokine productions. Results : The water extract of RG extract significantly inhibited the LPS-induced inTNF-
and IL-5 mRNA expressions, but the water extract of PT, CUM, GU, PG, and SC did not. The ethanol extract of RG, PT, and SC significantly inhibited the LPS-induced TNF-
, and IL-5 mRNA expressions, but the ethanol extract of CUM, GU, and PG did not. Conclusions : Theses results could suggest that the water extract of RG and the ethanol extract of RG, PT, and SC inhibited the expression of TNF-
and IL-5, which means that the possible candidate of OMC-2010 water extract's action might be RG, and ethanol extract's action might be RG, PR, and SC.

DOI : 10.6116/kjh.2012.27.6.55
Objectives : Allium Hookeri (AH) is a traditional herb to treat inflammatory diseases in India and Myanmar. Recently, AH cultivation was succeeded in South Korea. This study was performed to evaluate the anti-inflammatory effects of Korean AH in RAW264.7 cells, mouse macrophage cell line. Methods : To evaluate the anti-inflammatory effects of root of AH, we prepared the 70% ethanol extract, then we examined the productions of nitrite, and pro-inflammatory cytokines. To examine the nitrite, and cytokines, the RAW264.7 cells were treated with AH, then stimulated with lipopolysaccharide (LPS, 500 ng/ml) for 24 h. Then the cells were harvested for griess assay, ELISA and real-time reverse transcription polymerase chain reaction (RT-PCR). Also to detect the ability of AH to induce heme oxygenase-1 (HO-1), we examined the HO-1 expression using real time RT-PCR and western blot. Furthermore, we examined the mitogen activated-protein kinases (MAPKs) and nuclear factor kappa B (NF-
) activation to find out the underlying mechanisms. Results : AH ethanol extract significantly inhibited the productions of nitrite and interleukin (IL)-
. AH treatment increased the HO-1 expression dramatically at 1 h, then peaked at 3 h. When the HO-1 was inhibited by tin (Sn) protoporphryin-IX (SnPP), the anti-inflammatory action of AH was reversed. AH treatment inhibited the activation of p38, but not extracelluar signal-regulated kinase (ERK 1/2) and c-Jun
-terminal kinase (JNK) and also the degradation of inhibitory kappa B a (Ik-
) in the LPS-stimulated RAW 264.7 cells. Conclusions : These data could suggest that AH exerts anti-inflammatory influences through up-regulation of HO-1 and deactivation of p38.

Objectives : Decoction, in Korean Medicine, is a pharmacological method of extraction, by boiling, of dissolved chemicals, or herbal prescriptions, which may include stems, roots, bark and rhizomes. Decoctions differ from most teas, infusions, in that they are usually boiled. This study was performed to compare the difference of water decoctions extracted by different decoction extractor and extraction time and to analyze the reason of decoctions extracted by each decoction extractor have different taste. Methods : With water decoction samples by Pressure extractor, Non-pressure extractor and Ultrasonic waves merge extractor for 1 hr, 2 hr and 3 hr were investigated the yield and the concentration of hesperidin and glycyrrhizin by HPLC/DAD system in Pyungwi-san decoction. Results : The samples of each extractor were gradually increased the yield and the concentration of hesperidin and glycyrrhizin. The HPLC pattern of samples is similar. The yield and the concentration of hesperidin and glycyrrhizin of Ultrasonic waves merge extractor was most highest of the three. The rate of increase of the yield and the hesperidin concentration of between 1 hr and 2 hr in Pressure extractor was the most highest of the three. But the concentration of glycyrrhizin in Pressure extractor was relatively similar to Non-pressure extractor. Conclusions : The yield and the concentration of reference compounds in Pyungwi-san water decoction was influenced by extracting method and extracting time. For scientific movement and standardization of extracting medicinal herbs method need to study of extractor validation and to study in vitro and in vivo.

DOI : 10.6116/kjh.2012.27.6.71
Objectives : The purpose of this study was to evaluate the neuroprotective effect of Pueraria lobata extract on focal cerebral ischemia in mice. Methods : Focal cerebral ischemia was induced by occlusion of the right middle cerebral artery using the intraluminal filament model. ICR male mice underwent 90 minutes of middle cerebral artery occlusion (MCAo) followed by 24 hours of reperfusion. Mice were administered Pueraria lobata extract orally at the dose of 300mg/kg just prior to reperfusion. Rotarod test and balance beam test were practiced to assess sensory-motor function 23 hours after MCAo. In rotarod test, the latency to fall on the accelerating rotarod was recorded for 5 min. In balance beam test, the score was graded according to number of slips and latency to cross. The infarct volume was measured 24 hours after MCAo using 2% 2,3,5-triphenyltetrazolium chloride (TTC) staining. Results : Pueraria lobata extract treated group showed significant reduction in infarct volume by 27.3% compared to control group (p<0.05). In rotatod test, it also showed significant extension of latency time compared to control group (
, p<0.001). In contrast to performance in rotarod test, that in balance beam test did not improve with Pueraria lobata extract treatment. Conclusions : We conclude that Pueraria lobata extract has a significant neuroprotective effect and reduces damage of sensory-motor function in MCAo model. These findings suggest that Pueraria lobata could be a potent neuroprotective agent.

Objectives : The purpose of this research was to examine the oriental medical term 'Yukjin(in chinese, liuchen)' i.e. 'good long-term storage of the six oriental medicinal herbs'. Yukjin has meant the six sorts of drugs which were well known for the older they stored, the better efficacious they were. This research was carried out to obtain more conclusive information about the time and the reason of the giving a naming Yukjin, and to arrange Yukjin's properties, toxicities and processes. Methods : We investigated the documents recorded in the medical classics of Yukjin and did the current issues and recent experimental researches of these medicines. Results : 1. The properties and flavors of Yukjin are pungent and bitter. When they were stored for a long time after gathering, their toxicities and stimuli were growing thinner, regarded as positive clinically with age and they should be used after processing. 2. The efficacies of Yukjin are not always in proportion to storage period. In case, they are stored too long, their efficacies and qualities may be deteriorated though volatility or pungent flavors are enfeebled. Conclusions : Consequently, toxicities and strong flavors of Yukjin can be reduced in various processes. So the traditional theory of long-term preservation is not necessarily retained. It may be desirable to store them for 1 to 3 years after harvest, to safen their toxicities and adverse reactions in the way of processing. If we use them properly according to oriental medicine method, it will be effective on treating and preventing the various diseases.

DOI : 10.6116/kjh.2012.27.6.83
Objectives : Modified Bo-Yang-Hwan-O-Tang (mBHT) is a polyherbal medicine of twelve herbs traditionally used in the treatment of cerebral and cardiac stroke and vascular dementia. The purpose of this study was to evaluate the neuroprotective effect, pyramidal neuronal cell, inflammation and apoptosis of mBHT against global ischemia in rats. Methods : Global ischemia was produced by two-vessel occlusion(2-VO) in SD male rats. mBHT at dose of 500 mg/kg was orally administrated for 2 weeks or 6 weeks after global ischemia. The histopathological changes of ischemic brain were observed by staining of hematoxylin and eosin (H&E) and Nissl and immunohistochemisty with anti-GFAP (glial fibrillary acidic protein) antibody as a astrocyte marker. The expression of inducible nitric oxide synthase (iNOS) and apoptotic proteins such as Bax, Bcl-2 and caspase-3 was determined by western blot. Results : mBHT treatment significantly inhibited the pyramidal neuronal loss in CA1 of hippocampus of global ischemic rats by 2-VO. mBHT also suppressed the activation of astrocytes in the CA1 at 6 weeks after ischemia. In addition, mBHT significantly increased the expression of anti-apoptotic protein, Bcl-2 on iscemic brain, and significantly attenuated the expression of apoptotic proteins, Bax and caspase-3. Conclusions : These results indicate that mBHT inhibits neuronal cell damage induced in global ischemia by 2-VO, suggesting that mBHT may be a potential candidate for the treatment of vascular dementia.

Objectives : Rhodiola rosea L. (Crassulaceae) is a plant living at the areas of high-altitude mountain, and Rhodiolae Radix(the root of R. rosea) has been used as a traditional medicine to decrease the symptoms of mental- or physical-stress in Asia and Europe. To examine the efficacy of Rhodiolae Radix on the oxidative stress, the anti-oxidative effects of the radix were examined, Methods : The effects of Rhodiolae Radix on several oxidative factors were examined in vitro, and also the effects were tested in the liver of rats which were treated with a high dose of alcohol during 2 weeks. Results : The extract of Rhodiolae Radix in vitro scavenged some oxidants, such as DPPH, Superoxide anion radical and LDL, and the extract also inhibited the oxidative capacity of linoleic acid, significantly. Meanwhile, in the in vivo test, the methanol-extract decreased some oxidation parameters, such as relative liver weight, TBARS and SOD activities, and also increased catalase activity in the liver of alcohol-loaded rats, But, the extract had no effects on GSH content and GSH-px activiy in the rats. Conclusion : The root of Rhodiola rosea has a strong anti-oxidative capacity, and also has some preventive properties aginst the alcoholic stress.

Objectives : Korean red ginseng and Morus alba L. are used as a traditional treatment for diabetes. This study was designed to elucidate whether combination with Korean red ginseng and Morus alba L. (MPM) ameliorates metabolic syndrome in fructose-fed rats. Methods : 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 (HF) diet alone for 8 weeks, with supplementation with MPM or rosiglitazone occurring during the final 6 weeks. Results : MPM and rosiglitazone, synthetic
agonist, treatment significantly prevented the increase in fasting serum glucose, leptin, triglyceride, and low density lipoprotein in the HF group when comparing with the control group. MPM and rosiglitazone also led to an increase in high density lipoprotein level in the HF group. The administration of MPM and rosiglitazone prevented the development of the metabolic disturbances such as impaired glucose tolerance, and blood pressure. MPM suppressed increased expressions of endothelin-1 (ET-1) in HF rat aorta. In addition, MPM significantly increased IR-
expression in muscle. Conclusions : Based on these results, we suggest that the administration of MPM improves metabolic syndrome through the alteration in lipid profiles and suppression of insulin resistant and blood pressure.

DOI : 10.6116/kjh.2012.27.6.107
Objectives : In this study, we investigated the anti-diabetic and anti-inflammatory effects of water extract from leaves of Ligustrum japonicum (WLJ) in db/db mouse. Methods : The db/db mice were treated orally with WLJ (300 mg/kg/day) for 10 weeks to examine the long-term effects on hyperglycemia and glomerular tissue as well as biochemical and functional abnormalities in the kidney. Results : WLJ treatment markedly reduced plasma levels of glucose, triglyceride, creatinine, and systolic blood pressure in diabetic db/db mouse. Treatment of WLJ significantly increased plasma level of high density lipoprotein (HDL)-cholesterol. We also found that overexpressions of vascular cellular adhesion molecule (VCAM)-1 and endothelin (ET)-1 were observed in aortic tissue of db/db mouse, whereas, WLJ suppressed both expression of VCAM-1 and ET-1 in aorta. In renal tissue, overexpressions of ICAM-1 and TGF-
were found in untreated db/db mouse, however, significantly decreased those levels by WLJ treatment. The insulin immunoreactivity of the pancreatic islets remarkably increased in WLJ treated db/db mouse compared with untreated db/db mouse. Taken together, WLJ treatment ameliorated hyperglycemia and hyperlipidemia via improvement of insulin secretion and lipid metabolism, respectively. Furthermore, WLJ treatment also ameliorated hypertension via inhibition of inflammatory process in vascular and renal tissues. Conclusions : Ligustrum japonicum has an anti-diabetic and anti-inflammatory effects in db/db mouse. Thus, these results suggested a beneficial effect of Ligustrum japonicum in treatment with diabetes and diabetic vasculopathy.

). The activities of glycerol-3-phosphate dehydrogenase (GPDH) and leptin level were measured in 3T3-L1 cells. Results : The calibration curves showed good linearity (
=1.0000) for different concentration ranges. The contents of liquiritin, naringin, hesperidin, neohesperirin and glycyrrizin in 70% ethanol extracts of IS were relatively higher than that of water extract, however the content of ferulic acid in 70% ethanol and water extract of IS were similar. The extraction solvents of water and 70% ethanol were evaluated inhibitory effect on the production of NO,
and IL-6 in RAW 264.7 cells. Their extractions were inhibitory effect on production of MDC/CCL22 and RANTES/CCL5 in HaCaT cell and BEAS-2B cell, respectively. In addition, evaluated reduced on GPDH activity and leptin level in 3T3-L1 preadipocyte cell. Conclusions : Our results suggest that IS extracts were inhibitory effects of disease such as inflammation, allergies and obesity.

Objectives : Allergy has been described as an inflammatory with hypersensitivity resulting from seasonal or perennial responses to specific allergens. The root of Platycodon grandiflorum (Jacq.) A. DC.(Platycodi Radix; Campanulaceae) has been traditionally used to treat chronic diseases such as bronchitis, asthma, pulmonary tuberculosis, inflammation and hyperlipidemia. In this study, we examined the effect of 70% ethanol extract of Platycodi Radix (PR-E) on ovalbumin (OVA)-induced airway inflammation in mice. Methods : Mice were sensitized and challenged by OVA inhalation to induced chronic airway inflammation, and then were intragastrically administered PR-E extract at doses of 50 and 200 mg/kg/day from days 21 to 30 consecutively. The levels of allergic mediators such as histamine, OVA-specific immunoglobulin (Ig) E, and cytokines such as IL-4 and IFN-
were measured in the sera of mice by ELISA. The histological change of lung tissue was observed by hematoxylin and eosin (H&E) staining. Results : PR-E extract significantly decreased the serum levels of histamine, OVA-specific IgE, and Th2 cytokine, IL-4 compared with those in the OVA-induced group. PE-E extract significantly increased the serum level of Th1 cytokine, IFN-
. Based on lung histopathological studies, inflammatory cell infiltration and mucus hypersecretion were inhibited by PE-E extract administration compared to that in the OVA-induced group. Conclusions : These findings indicate that PE-E extract may be useful as an adjuvant therapy for the treatment of bronchial asthma.

Objectives : Cyclooxygenase (COX) plays a central role in the inflammatory cascade by converting arachidonic acid into prostaglandin. COX-2 is typically induced by inflammatory stimuli in the majority of tissues, it is responsible for propagating the inflammatory response and thus, considered as the best target for anti-inflammatory drugs. The present study investigated the modulatory effect of ginsenoside Rg3, a principle active ingredient in Panax ginseng, on COX-2 expression in the brain tissue induced by systemic lipopolysaccharide (LPS) treatment in C57BL/6 mice. Methods : Because systemic LPS treatment induces COX-2 expression immediately in the brain, ginsenoside Rg3 was treated orally with doses of 10, 20, and 30 mg/kg at 1 hour before the LPS (3 mg/kg, i.p.) injection. At 4 hours after the LPS injection, COX-2 mRNA was measured by real-time polymerase chain reaction method, COX-2 protein levels were measured by Western blotting. In addition, COX-2 expressions in brain tissue were observed with immunohistochemistry and double immunofluoresence labeling. Results : Ginsenoside Rg3 (20 and 30 mg/kg) significantly attenuates up-regulation of COX-2 mRNA and protein expression in brain tissue at 4 hours after the LPS injection. Moreover, ginsenoside Rg3 (20 mg/kg) significantly reduced the number of COX-2 positive neurons in the cerebral cortex and amygdala. Conclusion : These results indicate that ginsenoside Rg3 plays a modulatory role in neuroinflammation through the inhibition of COX-2 expression in the brain and suggest that ginsenoside Rg3 and ginseng may be effective on neurodegenerative diseases caused by neuroinflammation.

Objectives : This study aimed to investigate value differences among Gastrodiae Rhizoma samples(GM, GC, G1, G2 and G3) in various characteristics as well as to provide basic guideline for various processes such as steaming and drying of Gastrodiae Rhizoma. Methods : Gastrodiae Rhizoma were steamed and dried at different temperature and times. They were divided into samples (GM; cultivated, steamed and dried in Muju, GC; cultivated and dried in China, G1; steamed and dried at
for 60 hours, G2; steamed and dried at
for 120 hours, G3; steamed and dried at
for 120 hours) for experiment. They were extracted using water, freeze dried and powdered to analyze gastrodin content, antioxidant activity and sensory evaluation. Results : Proximate composition and the amount of free sugars of Gastrodiae Rhizoma had a little bit differences. Phenolic and flavonoid content of samples were increased by increasing drying temperature and times. Gastrodin content had different values by drying method and G3 was the highest in comparison with others. Increasing drying times led to a increasing in radical and nitrate scavenging activity in samples. Regarding to sensory evaluation, G3 was selected as the best sample according to its highest hedonic score mean (6.11/7) among all samples for appearance, color, flavor, overall acceptability. Conclusions : The results indicated that G3 sample was effective in views of antioxidant activity, gastrodin content and sensory characteristics. Moreover, Gastrodiae Rhizoma cultivated in Korea were investigated with higher antioxidant activity, gastrodin content and sensory characteristics than those cultivated in China.
