Background : Methicillin-Resistant Staphylococcus aureus (MRSA) is a multidrug-resistant (MDR) strain. Especially, MRSA is developing resistance to available antibacterial agents and causing complications in the treatment of infections related to skin, soft tissue, respiratory, bone, joint, and endovascular disorders. Therefore, antibacterial agent combination therapy appears to be a useful option, particularly in developing countries where antibiotic availability is limited. (+)-Usnic acid (UA) is uniquely found in lichens, and is especially abundant in genera such as Usnea and Cladonia. UA has antimicrobial activity against human and plant pathogens. Therefore, UA may be a good antibacterial drug candidate for clinical development. Methods and Results : In search of a natural products capable of inhibiting this multidrug-resistant bacteria, we have investigated the antimicrobial activity of UA against MRSA. In this study, the effects of a combination of UA and permeable agents against MRSA were investigated. For the measurement of cell wall permeability, UA with concentration of Ethylenediaminetetraacetic acid (EDTA) was used. In the other hand, Sodium azide (NaN3) was used as inhibitors of ATPase. These results suggest that the antibacterial effect of UA was potentiated by membrane-binding agents and ABC transporter-inhibiting agents, implying that antibacterial activity is associated with damage of the cell wall and inhibition of ATPase function by UA. Conclusion : UA and in combination with EDTA and NaN3 could lead to the development of new combination antibiotics against MRSA infection. The results of this study appear to be promising, and they are expected to enhance the use of natural products as drugs.

Background : Although ginseng has various bioactive compounds in it, there is lack of study on the variations of bioactive compounds in ginseng according to the cultivation soil and the applied fertilizer types (or amount). Therefore, this study aims to examine the variations of 37 fatty acids (FA) and 8 vitamin E (Vit-E) vitamers in 6-year-old ginseng root cultivated in different soil types with different fertilizers regimes. Methods and Results : The profiling of 37 FAs and 8 Vit-E vitamers in 6-year-old ginseng roots was measured by gas chromatography coupled with a flame ionization detector, and then these results were statistically analyzed with chemometrics. The FA and Vit-E content in ginseng roots varied significantly with respect to soil cultivation conditions due to organic fertilizer types and amounts used. Unsaturated FA in ginseng is approximately 2.7 fold higher than the saturated FA. Linoleic, palmitic, and oleic acids were the most abundant FAs found in the ginseng roots. Also, the major Vit-E vitamer found in ginseng root is α-tocopherol. In particular, the application of rice straw compost or food waste fertilizer was increased to create nutritionally desirable FAs and bioactive Vit-E in ginseng root. In addition, phytonutrient profiling coupled with chemometrics can be used to discriminate the cultivation conditions of ginseng. Conclusion : This study extends our understanding about the variations of FA and Vit-E in ginseng root depending on cultivation conditions. Hence, these results can be useful as basic information for reliable ginseng production containing high amounts of phytonutrients in a paddy-converted field.

Background : The geographical origin of Panax ginseng Meyer, a valuable medicinal plant, is important to both ginseng producers and consumers in the context of economic profit and human health benefits. We therefore aimed to discriminate between the cultivation regions of ginseng using the stable isotope ratios of C, N, O, and S, which are abundant bio-elements in living organisms. Methods and Results : The C, N, O, and S stable isotope ratios were measured by isotope ratio mass spectrometer, and then these isotope ratios profiling was statistically analyzed with chemometrics. The various isotope ratios found in Panax ginseng roots were significantly influenced by region, cultivar, and the interactions between these two factors (P ≤ 0.0002). In particular, δ18O was lower in ginseng roots grown at high altitudes (r = −0.47), while δ34S was higher in ginseng roots grown close to coastal areas (r = −0.48). Chemometric results provided discrimination between the majorities of different cultivation regions. Conclusion : Our case study extends the understanding about the variation of C, N, O, and S stable isotope ratios in ginseng root depending on cultivation region. Hence, the analysis of stable isotope ratios is a suitable tool for discrimination between the regional origins of ginseng samples from Korea, with potential application to other countries.

Background : Undulatum Rhubarb, commonly produced in domestic, is rhizome of Rheum undulatum L. that belongs to the family Polygonaceae. It also can be used as a substitute of R. palmatum L., R. tanguticum Maximowicz ex Balf., and R. officinale Baillon which completely depend on import system. However, there should be clear clarification among Undulatum Rhubarb and Rhubarb, because Undulatum Rhubarb contains rhaponticin as marker compound that is not indicated at Rhubarb. Some of the recently imported Undulatum Rhubarbs have been found to be Rhubarb. Also, it is known that only Undulatum Rhubarb is cultivated at domestic environment. But some plant origins of Rhubarb are grown in Korea, too. Further study are needed to clarify clear origin between Undulatum Rhubarb and Rhubarb. Thus, we collected some domestically cultivated samples and identified them. Methods and Reseults : Rheum undulatum L., Rhubarb, Rheum tanguticum Maximowicz ex Balf. which were cultivated in Gangwondo Agricultural Research and Extension Services in Cheorwon were collected and anayzed the DNA sequences. We also compared DNA sequences in Rhubarb collected from England and R. rhabarbarum L., R. undulatum L., and R. franzenbachii on NCBI. As a result, two kinds of rhubarb cultivated in the test plantation were identified as R. rhabarbarum and R. officinale. In addition, R. undulatum (plant origin of Undulatum Rhubarb) was identified as Rhubarb (Rheum rhabarbarum) in England with 99 - 100% identical in nuclear ITS gene region. Conclusion : R. undulatum, plant origin of Undulatum Rhubarb, is reported as synonym of R. rhabarbarum, R. franzenbachii. Rheum speices which are cultivated as tester in Gangwondo Agricultural Research and Extension Services in Cheorwon are estimated as R. undulatum and R. officinale. Therefore, not only Undulatum Rhubarb but Rhubarb could be grown in Korea.

Background : Capsaicin is an active component of chili peppers, which are plants belonging to the genus Capsicum. Research reported capsaicin has antioxidant and anti-inflamatory activity and osteoclast lineages are very susceptible to oxidative stress, as osteoclasts are produced by increased-generation of intracellular ROS and osteoclasts are activated by ROS. Therefore, our study was evaluated the influence of intracellular oxidative stress such as increased ROS level on RANKL-mediated osteoclast differenciation. Methods and Results : Capsaicin showed a good free radical scavenging activity at in-vitro antioxidant activity. The inhibitory effect of osteoclast differentiation on capsaicin was confirmed. Osteoclast differentiation from murine macrophage RAW 264.7 cells was induced by RANKL. The effect of capsaicin on receptor activator of nuclear factor-κB (NF-κB) ligand (RANKL)-induced osteoclast differentiation was demonstrated using a tartrate-resistant acid phosphatase (TRAP) assay and TRAP staining. Capsaicin showed an inhibitory effect on TRAP activity. The TRAP staining showed that the number of TRAP positive osteoclasts was reduced in capsaicin-treated cells. Conclusion : Capsaicin revealed an inhibitory effect in osteoclast differentiation induced by RANKL. These results suggest that capsaicin may have a beneficial effect for the prevention or treatment of osteoclast caused bone diseases such as osteoporosis.

Background : Corrosion is one of the most devastating problems faced by most industries. Mild steel has played a vital role in various fields due to the excellent mechanical properties of mild steel such as low density, high strength-to-weight ratios, good environmental stability, high thermal conductivity, and corrosion resistance. Methods and Results : The total phenolic contents (TPC) and total flavonoid contents (TFC) of the methanolic extract of C. grandiflora and R. verniciflua leaf have been examined, and its corrosion inhibition performance was investigated by weight loss and electrochemical impedance spectroscopy (EIS) and polarization measurements. The surface morphology of mild steel was analyzed by scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectroscopy (EDX) and by atomic force microscopy (AFM). The percentage composition of polyphenolic compounds was found to be higher in C. grandiflora and R. verniciflua plant extracts, and it was proved to be a superior, eco-friendly, and anti-corrosive inhibitor for mild steel in 1M of H2SO4. The Tafel polarization studies indicate that the plant extract is a mixed-type inhibitor. Scanning electron microscopy/energy -dispersive X-ray spectroscopy (SEM-EDS), and atomic force microscopy (AFM) studies confirmed the formation of a protective film on the metal surface. The corrosion inhibition of the C. grandiflora and R. verniciflua plant extracts was characterized by Fourier transform infrared (FT-IR), UV-visible spectra, and wide-angle X-ray diffraction (XRD) studies; these show the strong interaction between the metal surface and the inhibitor. Conclusion : The methanolic extract was prepared the two different plants like C. grandiflora, and R. verniciflua was studied the corrosion inhibition on the mild steel specimen in acidic medium through various methods involving weight loss measurements, EIS, and potentiodynamic polarization. The results shows that the C. grandiflora, and R. verniciflua plant extracts illustrate an effective corrosion inhibitor for mild steel with good anticorrosion properties in acidic environmen

This study was conducted to investigate the antibacterial, antioxidant, and in vitro greenhouse gas mitigation activities of fermented Scutellaria baicalensis Georgi extract. Seven starter cultures were used, comprising four of lactic acid bacteria and three of Saccharomyces cerevisiae. Ten grams of S. baicalensis Georgi powder was diluted in 90 mL autoclaved MRS broth. Each seed culture was inoculated with 3-10% (v/v) S. baicalensis Georgi MRS broth and incubated at 30℃ for 48 h. Among the starter cultures used, only Lactobacillus plantarum EJ43 could withstand the fermentation conditions. This fermentation broth was dried and extracted with ethanol to assess its antibacterial, antioxidant, and in vitro methane mitigation activities. The extract of S. baicalensis Georgi fermented by L. plantarum EJ43 (SBLp) showed higher antibacterial activity (bigger clear zone) compared to the unfermented S. baicalensis Georgi extract (SB0). SBLp also presented 1.2 folds higher antioxidant activity than SB0. During in vitro rumen fermentation, SBLp showed reduction in methane production compared to SB0 or the control. In conclusion, fermentation by L. plantarum EJ43 may enhance antibacterial and antioxidant activities of S. baicalensis Georgi and decrease enteric methane production.

Research has found that the management of the host plant is essential to mistletoe cultivation. A Trunk injection test on the host plant that contained a mixture of indole-3-butryc acid (IBA) and liquid fertilizer was conducted with respect to the improvement of the one year survival rate of mistletoe. As a result, the trunk injection experiments showed the effect of the IBA and liquid fertilizer mixture in all treatments. This mixture was effective to increase the survival rate of mistletoe by 20% with the IBA at 100 ㎎/L and Hyponex at 100 ㎎/L. The examination proved that the host plant fertilizer effect was the most effective treatment for organic fertilizer with 60% added NPK (4-2-1). Its effects were higher compared to the control at the length and diameter of one-years-old branches in the host plant, even when the parasitic mistletoe improved its growth in length, diameter, and number of branches. Comparing the control and host plant fertilizer, the latter was the most effective way to process 20 ㎏ per a treatment effect in the experimental site and to process at any time after the inoculation. This treatment is effective to improve the growth of mistletoe by watering the host plant three times per week. Therefore, the management of the host plant is an essential element in the successful cultivation of mistletoe, not only to supply fertilizer and plant hormones to the host plant in the initial inoculation time but also to provide organic fertilizer and irrigation for the host plant.

Sexual dimorphism is the most conspicuous difference between the sexes. This study examines possible sexual dimorphism and the relative growth patterns of morphometric characteristics in the marine medaka, Oryzias dancena for their potential to help differentiate between males and females of this species. The von Bertalanffy growth parameters estimated by a non-linear regression method were L∞=30.2 mm, K=3.22/year, and τ0=-0.05. All 18 characteristics measured showed a difference between males and females from 70 days after hatching. Each of these characteristics were significantly different between sexes (ANCOVA, P<0.05), and the ratio of standard length between sexes showed that males were larger than females for all five morphometric measurements. Fin length measurements were taken for 21 distances of anal fin and 7 distances of dorsal fin between landmarks. There were all differences for all dorsal fin rays between the males and the females and there is significant difference in 70 days after their hatch when the sexual dimorphism is presented. The significant difference (P<0.05) in fin ray for male and female was more greatly seen as they grow. Male marine medaka showed more rapid growth than females, with longer length, dorsal fins and anal fins. Differences in these characteristics will be useful during experiments when it is necessary to differentiate between sexes of marine medaka.

The aim of this paper is to investigate the syntactic structure of the so-called transparent relative clause. What in the standard free relative clause has been treated as a unit including a head NP and a relative pronoun together. In the case of transparent free relatives, however, a what-clause reveals some peculiar characteristics different from standard relative clauses. To explain those characteristics, many linguists have suggested several different analyses. The analyses can be categorized into three groups: Backward Deletion, Shared Structure analysis, (Rightward) Movement and Deletion analysis. Because of their drawbacks, I have suggested Leftward Movement and Deletion analysis, and adopted Winkler's(2005) D(rivational)-Model of Grammar to explain the interactions between the PF deletion and LF interpretation.

The study aimed to evaluate the usability of sterile bag collection (SBC) urinalysis and urine culture for diagnosing urinary tract infections (UTI). Urine culture is key for diagnosing UTI, and transurethral catheterization (TUC) or suprapubic aspiration is recommended for non-toilet-trained children. Although urine testing using SBC is non-invasive and easy, UTI can be diagnosed only if other criteria including clinical symptoms and positive urinalysis results are met. This study included 228 infants who were hospitalized for unexplained fever from October 2015 to June 2016. TUC culture, SBC urinalysis, and urine culture were performed for all patients. UTI was diagnosed when the TUC culture results met the criterion of ≥104 colony-forming units (CFU)/mL. When UTI diagnosis was made based on SBC urine colony counts ≥105 CFU/mL, the false-positive and false-negative rates were 6.3% and 70.0%, respectively. When the criterion was set as ≥104 CFU/mL, they were 23.7% and 30.0%, respectively. When both the criteria of ≥105 CFU/mL and positive urinalysis results were met, the false-positive rate was 2.4%, and the false-negative rate was 80%. Our results suggest that diagnosing UTI using SBC urinalysis and urine culture is not useful in infants with unexplained fever.

Also, for seed number, the correlation coefficient is the fruit weigh t (0.643**), fruit width (0.640**) was significantly more than the length (0.532**). Conclusions : Camellia japonica was very various size, shape of fruit and seed number of per fruit.

Background : Lactuca sativa (LS) is a member of lactuca genus and the Asteraceae family. To its usual purpose as an edible leafy vegetable, lettuce has had a number of uses in ancient times as a medicinal herb. Depending on the variety, lettuce is an excellent source vitamin K and vitanin A. Methods and Results : The objective of this study is to find out the antioxidant and oxidative DNA damage prevention capacity of LS for both water and ethanol extract. The total phenolic and flavonoid contents have been estimated in this study. The extracts have been tested to assess the 1, 1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2ʹ -azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and nitrite scavenging activity. We have also evaluated the reducing power activity of LS. LS extracts showed a good radical scavenging activity on DPPH and ABTS free radical as concentration dependent manner. The IC50 values on DPPH radical scavenging activity were 0.75 mg/mL and 0.54 mg/mL for water and ethanol extract respectively. ABTS radical scavenging activity ranges from 38-89 % for water extract and 33-96% for ethanol extract. Although ethanolic extract showed a higher radical scavenging activity as compared to the water extracts. All the extracts exhibited reducing power activity, dose dependently. Moreover, when the DNA was treated with the extracts, supercoiled DNA was restored in a concentration-dependent manner. Conclusion : According to the results, we suggest that LS contains considerable amount of phenolic and flavonoid content and could be used as a source of natural antioxidant substances and oxidative DNA damage preventer.

Background : Alzheimer`s disease (AD) is characterized by neuronal loss and extracellular senile plaque, whose major constituent is β-amyloid (Aβ), a 39-43 amino acid peptide derived from amyloid precursor protein. In cultures, Aβ can directly induce neuronal cell death and can render neurons vulnerable to excitotoxicity which may involve glutamate release and N-methyl-D-aspartate (NMDA) receptor. Silybum marianum (SM) has been used for centuries to treat liver disease due to its antioxidant, and anti-inflammatory properties. In particular, Silymarin, an active constituent of SM, has been reported to decrease lipid peroxidation. Therefore we hypothesized that SM might protect neurons against neurodegeneration in AD due to its antioxidant and anti-inflammatory activities. In the present study, the protective effect of ethanol extract from the stem of SM on Aβ (25-35)-induced neuronal cell death was examined in primary cultured rat cortical neurons. Methods and Results : Primary cultured cortical neurons were prepared using embryonic day 15 SD rat fetuses. Neurotoxicity experiments were performed on cultured neurons after 4-5 days in vitro. The cells were treated with 10 μM Aβ (25-35) or 1 mM NMDA for 36 h or 14 h, respectively. SM was applied 15 min before treatment of Aβ (25-35) or NMDA and also present in the medium during the incubations. The viability of neurons was monitored using a colorimetric MTT assay and Hoechst 33342 staining. The expression levels of anti-apoptotic and pro-apoptotic proteins were detected by western blot. An Ethanol extract of the stem of SM (10 and 50 μg/ml) significantly prevented Aβ (25-35)-induced apoptotic neuronal cell death in cultured cortical neurons. Furthermore SM inhibited Aβ (25-35)-induced decrease of anti-apoptotic protein, Bcl-2, and increase of pro-apoptotic proteins, Bax and active caspase-2, in western blot analysis. SM (10 and 50 μg/ml) also reduced NMDA-induced neuronal cell death. These results suggest that NMDA glutamate receptor activation is implicated in Aβ (25-35) -induced neuronal apoptotic death. Conclusion : The present study suggests that SM has a possible therapeutic role for preventing the progression of neurodegenerative disease such as Alzheimer's disease.

Background : This study analyzes changes in DPPH radical scavenging activity, total polyphenol contents, and total flavonoid contents of six different kinds of Kenaf (Hibiscus cannabinus L.) leaves which are identified as herbaceous plants, and are living in the subtropics. The data of changes in polyphenol, flavonoid contents and DPPH radical scavenging activities were analyzed, based on two different lengths of growth period.. Methods and Results : The six different kinds of cultivars ; Jangdae in Korea, and El-1, R, G-1, Ef-1, Ef-2 in the State of Israel were collected on the 43th and 62nd day from when they have planted. The collected cultivars were dried at 70℃, and 80% of methanol concentration was applied to each ground specimen. Extraction was made by immersion and filtering process at room temperature. Samples were classified into two groups, one for cultivars that were collected on the 43th day, and the other for the collection of the 62nd day. We measured the rate of DPPH radical scavenging activity, total polyphenol contents, and total flavonoid contents for every Samples. For the group of the 43th day collection, Jangdae showed the highest rate of radical scavenging activity as well as the highest polyphenol contents, and El-1had the highest flavonoid contents. For the group ofthe 62nd day collection, R demonstrated not only the highest contents of polyphenol and flavonoid, but alsothe highest rate of antioxidant activity. When we compared each cultivar from another regardless its date of collection, R resulted biggest increase in all of functional components. Conclusion : Based on the test results, useful components and antioxidant activity of kenaf leaves increase in proportion to longer growing period. Particularly, the study indicates that R can be utilized as a cosmetic ingredient crop, as the rate of increase in polyphenol and flavonoid contents were highest among the six cultivars.

Background : Invitro antioxidant activity, polyphenol and flavonoid aglycone contents in black and green tea products of balloon flower leaves were investigated to provide valuable information for the further development and utilization of resources of Platycodon grandiflorum. Methods and Results : Flavonoid aglycone contents were investigated using HPLC (SHIMADZU, Japan) with a hypersil ODS column (125 mm × 4 mm, 5-μm particle, HP). DPPH and ABTS radical scavenging activities were measured by method of Lee & Lee (2004) with slight modification. Antioxidant activity, polyphenol and flavonoid contents in green tea were significantly higher than these in black tea. PC analysis indicated that first principal components explained 79.9% of the total variability for five traits investigated. PC2 explained 19.7% of the variation. Conclusion : It can be concluded from these results that these characteristics can reveal the active compound variation of black and green tea products of balloon flower leaves. These results provide scientific evidence for the utilization of balloon flower leaves.

Background : Achyranthes japonica Nakai (AJ) is a perennial herb with a wide distribution in East Asia including Korea, China, and Japan, and it is mainly used as a medicinal plant. In Korea, AJ has been widely used to control pain and improve symptoms in OA patients. AJ contains several important phytochemicals such as saponins, inokosterone, ecdysterone, and oleanolic acid bisdesmoside. Methods and Results : The aim of this work was to investigate the antioxidant and anti-inflammatory activities of fermented and ethanol extracts of Achyranthes japonica Nakai (AJ). The extracts showed strong reductive power and nitrite scavenging, hydroxyl radical scavenging, superoxide radical scavenging, and DNA damage prevention activities. Treatment of RAW 264.7 macrophages with AJ inhibited lipopolysaccharide (LPS)-induced NO secretion and iNOS expression without affecting cell viability. AJ also inhibited cyclooxygenase 2 (COX-2) expression, leading to the suppression of COX-2-derived prostaglandin E2 production. These inhibitory effects of AJ were accompanied by reduced production of tumor necrosis factor-α and interleukins (IL)-1β, -6, and -10. Furthermore, AJ suppressed LPS-induced phosphorylation of extracellular signal regulated kinase, c-Jun N-terminal kinase, and p38. Moreover, AJ inhibited malondialdehyde production and myeloperoxidase activity in LPS-stimulated RAW 264.7 cells. Conclusion : The antioxidant activity of plants is closely related to their medicinal properties and is widely used as a parameter to determine the bioavailability of medicinal plants. The antioxidant and biological activities of AJ extracts might be due to the synergistic actions of multiple bioactive compounds. It can be concluded that AJ extracts are a potential source of biologically important drug candidates.
