  • This study was conducted to evaluate in vitro antioxidative and antimicrobial properties of ethanolic extracts from Allium victoriallis L. var. platyphyllum (AVP) with 6 different parts. The antioxidative activities of these samples were determined using the 4 separate methods that involved reducing power, DPPH, hydrogen radical scavenging, and lipid peroxidation with use of a $\beta$-carotene/linoleic acid system. The leaf part ethanolic extracts (1,000 ppm) showed the strongest inhibitory potential for reducing power, DPPH, and hydroxyl radicals to 99.8, 49.4, and 52.8%, respectively. Inhibition values of linoleic oxidation were calculated as 58.0, 39.5, and 38.0% for seed, flower, and leaf ethanolic extracts (1,000 ppm), respectively, from AVP. In addition, the ethanolic extracts of the root part showed the most effective antimicrobial activity. The inhibition zones of the root ethanolic extracts ($200\;{\mu}g/disc$) of AVP against Bacillus cereus and Staphylococcus aureus were 17 and 14 mm, respectively. In a micro-dilution assay, B. cereus, S. aureus, and Vibrio parahaemolyticus exhibited sensitivity to root part ethanolic extracts with an minimum inhibition concentration (MIC) value of 20, 28, and 18 mg/mL, respectively. Therefore, the AVP extracts may be suitable as antimicrobial and antioxidative agents in the food industry.

  • Hibiscus syriacus (H. syriacus) as the national flower of Korea has been used as the herbal medicine in Asia. In this study, we evaluated the anti-inflammatory effect of 70% ethanol extracts from the root of Hibiscus syriacus (RHS-E70) and elucidated the potential signaling pathway in LPS-stimulated RAW264.7 cells. RHS-E70 dose-dependently suppressed NO production by inhibiting iNOS and IL-${\beta}$ expression in LPS-stimulated RAW264.7 cells. RHS-E70 inhibited the phosphorylation and degradation of $I{\kappa}B-{\alpha}$, which contributed to the inhibition of p65 nuclear accumulation and NF-${\kappa}B$ activation. Furthermore, RHS-E70 suppressed the phosphorylation of ERK1/2 and p38, which results in the inhibition of ATF2 phosphorylation and subsequent nuclear accumulation. These results indicate that RHS-E70 may exert anti-inflammatory activity by inhibiting NF-${\kappa}B$ and MAPK/ATF2 signaling. From these findings, RHS-E70 has potential to be a candidate for the development of chemopreventive or therapeutic agents for the inflammatory diseases.

  • Purpose : This paper explores the extent to which ZangFu diagrams made after Northern Song Dynasty were influenced by ZangFu diagrams made before Northern Song Dynasty, and how diagrams of the whole body and heart originated from MingTangZangFuTu and affected each other when quoted in books published after Northern Song Dynasty. Method : The author used four form factors including heart shape, internal curved lines, cylinder-like structures above heart, and wuzangxi (五臟系) which resembles a lotus flower which has not yet bloomed, to analyze and compare different ZangFu diagrams before and after the Northern Song Dynasty. Results : Two form factors, the shape of heart and wuzangxi, are described in ZangFu diagrams before Northern Song, and may have influenced ZangFu diagrams after Northern Song. However, the other two form factors (internal curved lines and cylinder-like structures above the heart) did not influence ZangFu diagrams after Northern Song. All form factors of heart found in WuCangLiuFuZhiTu (within the whole body) and diagram of heart in ZhenJiuJuYing (鍼灸聚英) were most similar, but the two paintings became less similar as they were cited in several books. With the exception of the form factor with structures above heart, the three other form factors are almost identical between two paintings produced after Northern Song dynasty, as displayed in the same book. Conclusion : ZangFu diagrams of the heart produced after Northern Song Dynasty, were not completely based on ZangFu diagrams made before Northern Song Dynasty. Diagrams of whole body and those of the heart were changed, while influencing each other after Northern Song.

  • Exochorda serratifolia, broad-leaved shrub has beautiful flowers and is resistant to cold, shade and decease. New this native plant is considered to be worth being exploited as the outstanding plant for landscaping and horticulture. So this study was executed to utilize Exochorda serratifolia as the planting material for landscaping and horticulture through the survey of its habitat environment and the experimennt of its seed physiology and germination, vegetative propagation, culture and utilization, etc.. The results are as follows ; 1. The color of the flower is white, blooming in the early and middle of May and the seeds ripen late in Sep.. 2. The elevation, elevation, gradient and direction of the native habitat were 250m, 20-25$^{\circ}$and northern side respectively. 3. The soil pH of the natural habitat was 5.3 and soil fertility was poor. 4. Exochorda serratifolia appeared as indicator within P. densiflora community and its neighboring species were Q. mongolica, Q. dentata, R. mucronulatum, L. obtusiloba, E. oxyphillus, C. heterolphylla, var thunbergii, etc.. 5. The optimum temperature for seed germination was found at 20$^{\circ}C$ and the longer the stratification period at 5$^{\circ}C$ was, the lower the germination rate was. 6. The treat merits of GA and Kinetin increased the seed germination rate, especially under the dark condition but their high concentrations decreased the seed germination rate. 7. The rooted rate of the greenwood cutting was the highest at IBA 100ppm plot of vermiculite bed but its high concentration decreased the rooted rate conspicuously. 8. In the tissue culture, the each 1.0 ppd plot of NAA, Kinetin and NAA 1.0ppm + Kinetin showed the best growth. And the mixture of NAA 1.0ppm and Kinetin showed better growth than the single treatment of NAA or Kinetin did. 9. Transplanted Exochorda serratifolia showed healthy growth with shaded environmental condition(42.1% light intensity), therefore they can be cultivated as a shade tolerant landscape plant. 10. It was considered that Exochorda serratifolia was applicable to group planting at shade places or under trees in parks, homes, etc..

  • The background of Korean Ethnical Costume was originated from those northern mounted nomadic groups, which was Scythe style Costume Culture. Through the antique records and paintings of tombs bequests hereby describe the forms of Scythian Cotume (1) Headgear : There was Conical Cap(or Pointed Cap), Feathered Cap, and Crown. (2) Clothes : Both Men and Women wore Jacket as upper garment with leftsided collars, narrow sleeves to the length of the hip line. As lower garment, they wore the tight Trousers and Kungo(:窮袴)that was attached with gusset. (3) Belts and Boots : On the upper garment bound the leather Belts that was hanged a hook that was shaped of animal form at the end. Scythian Buckles was divided into six groups, animal-shaped, animal's head shaped, animal fight-shaped, rectangle-shaped, rectangle openwork-shaped, genre scene shaped Buckle. To the Boots, they wore leather boots. (4) Ornaments : Ornaments divided into Dress Trimming(:Gold plaques), Earrings, Necklaces(;Torques), Bracelets, Rings. Scythian Gold Plaques were divided into several types according to the shape, animal style(curved beast shape, profile shape, head reversed over its back shape), round shape, quadrilateral form, star shape, flower shape, crescent shape, bundle shape, human appearance. Earrings consisted of a plain ring and pendant ring was a middle ornament hung from it to a pendants which hung was made of heart shaped leaves of the tree, beads-linked. Scythian Torques were divided into several types according to the shape, Torque with Terminal style, Spiral style, Layers style, Crescent-shaped pectoral style, Crown style. Scythian Bracelet were divided into 4 styles according to the shape, Bracelets with ends shaped like beasts style, Spiral style, Layers style, Crown with openwork style. Rings were rhomb-shaped and animal shaped styleRings (5) Animal motifs used in Scythian ornaments appears that in some cases the work was intended to be purely ornamental, while many times the motifs had symbolic meaning (such as the successful dominance of the aggressor over the victim portrayed in the attack scenes). Magical use of symbols may have been inten-ded to guarantee the power of the aggressor.

  • As there has recently been growing interest in Alternative Medicine, Oriental Medicals have been trying to incorporate Alternative Medicine into Oriental Medicine evolutionarily. The purpose of this study is to make a comparative study of the historical background and present condition, the view of life, the principle of therapeutics, and the various therapeutics in Alterative Medicine and Oriental Medicine from the viewpoint of Oriental Medicine. The conclusion of this study is; 1. Although Alternative Medicine has become influential mainly in the effort of finding a solution the limit of western medicine, the clinical effect of Alternative Medicine should be verified continuously. 2. Alternative Medicine includes all of the therapeutics such as Traditional Medicine, Naturopathy, Complementary Medicine and Selective Medicine whose characters are different from Western Medicine and Oriental Medicine can be regarded as a sort of Alternative Medicine. 3. The holistic, systematic view of life of Alternative Medicine, from which viewpoint human considered as a harmonious vital existence, is a sort of recurrence to the view of Hipporcrates. 4. From the viewpoint of Alternative Medicine, a disease is not partial but holistic disorder and is treated by utilizing natural products as a medicine based on the principle that pursues harmonious and balanced psychosomatic function. This principle of therapeutic is the same as Oriental Medicine is based on. 5. Alternative Medicine may be classified largely five category, (1) Eastern Therapy, (2) Manipulative Therapy, (3) Natural Therapy, (4) Active Therapy, (5) Therapy Involving External Powers. 6. Besides Alternative Medicine which is used in clinical treatment, Massage, Homeopathy, Bach Flower remedies, Meditation, and other Music Therapy and Color Therapy is relatively accordant with therapeutics in Oriental Medicine and should be more actively accepted in clinics and improved.

  • Three strains of Cucumber mosaic virus (CMV) have been found to cause a lethal disease, referred to as fern leaf syndromes and mild mosaic symptoms in tomato (Lycopersicon esculentum Mill.) crops grown in Kuwait. CMV strains were detected and identified based on host range, symptomatology, serology, electron microscopy, and ribonucleic acid (RNA) electrophoresis in polyacrylamide gels. A high degree of viral genomic heterogeneity was detected among CMV strains isolated in Kuwait, with no apparent correlation to symptomatology in tomato host plants. Two different virus satellites of 'CMV associated RNA 5', designated CARNA 5, were detected in two virus strains that caused both lethal disease and mild symptoms, designated CMV-D1 and CMV-S1 respectively. CARNA5 was not detected in the third CMV strain that caused fern leaf syndromes designated CMV-F. All the three isolated strains were serologically indistinguishable from each other and may belong to one serotype according to Ouchterlony gel diffusion tests. These strains transmitted via aphids (Myzus persicae Sulz) in a non-persistent manner. Physical properties of the virus strains were very similar where thermal inactivation test showed that virus withstood heating for 10 min at $70^{/circ}$, dilution end point was $10^{-4}$, and the longevity in vitro at room temperature was less than 5 days for all virus strains. CMV-D1 and CMV-F were the most devastating diseases spreading in both greenhouse and field-grown tomato where aborted flower buds failed on fruit setting due to the viral infection. This is the first report to isolate three different strains of CMV in Kuwait.

  • Aldose reductase (AR), the principal enzyme of the polyol pathway, has been shown to play an important role in the development of the diabetic complications. Evaluating natural sources for ARI potential may lead to the development of safer and more effective agents against diabetic complications. Sixty four Chinese herbal medicines have been investigated for inhibitory activities on AR. Among them, thirteen herbal medicines, Inula helianthus-aquatilis C. Y. Wu ex Ling. (whole plant), Erigeron breviscapus (Vant.) Hand. Mazz. (whole plant), Lonicera hypoglauca Miq. (leaf, stem), Scutellaria orthocalyx Hang. Mazz. (whole plant), Berchemia floribunda Brongn. (leaf, stem), Michelia alba DC. (flower), Oroxylum indicum (seed), Punica granatum L. (peel), Elsholtzia capituligera (whole plant), Trachelospermum jasminoides (Lindl.) Lem. (whole plant), Elsholtzia strobilifera Benth. (whole plant), Agrimonia pilosa var. nepalensis (D. Don) Nakai (whole plant) and Aster poliothamnus Diels (whole plant) exhibited a significant inhibitory activity against AR. Particularly, Inula helianthus-aquatilis C. Y. Wu ex Ling. showed seven times more potent inhibitory activity than the positive control, 3,3-tetramethyleneglutaric acid (TMG).

  • An understanding of anthracnose (Colletotrichum acutatum) infections, including the infection of flowers and latent infection early in the season, is necessary to achieve successful control by means of properly timed spraying with a curative fungicide. In the present study, latent anthracnose infection of chili was investigated under greenhouse and field conditions in 2007-2008. Flowers on greenhouse-grown seedlings were infected and 11% of the young fruits subsequently showed symptoms of anthracnose. Apparently healthy-looking green peppers obtained from unsprayed fields or an organic market also exhibited symptoms of anthracnose after 4 days of incubation under high moisture conditions at $25^{\circ}C$; less than 1% of the peppers were found to be latently infected. To determine the natural timing of infection in the field, 3,200 fruits were wrapped in paper bags and then selectively unwrapped and examined for signs of infection. Field experiments were conducted at Suwon (cvs. Yokkang, Manitta, Olympic) and Asan (cv. Chunhasangsa) in 2008. The 7- to 10-day wrapping periods were July 25-31, July 31-August 7, August 7-15, August 15-24, and August 24-September 3. The 1-to 2-month wrapping periods were from July 4, July 31, and August 15 until harvest (Sept. 3). The controls consisted of 1,712 field-grown non-wrapped fruits. The rates of infection on the various cultivars were Yokkang 55%, Manitta 37%, Olympic 55%, and Chunhasangsa 20%. A distinct period in which anthracnose infection suddenly increased could not be identified; however, attempts to guess the approximate timing of field infection showed that 0-39% of the plants had latent infections, while depending on the cultivar, 8-14% of the plants examined in August and 4-13.5% of the those examined during May-July showed symptoms of infection. Delaying fungicide spraying by 24 and 48 h after artificial infection decreased the rates of infection by 10% and 25-30%, respectively. Chemical control of anthracnose based on a forecasting model should be considered starting from the transplanting stage, with spraying within a day after warning and care being taken not to latently infect apparently healthy pepper fruits.

  • In this study, we determined the anti-inflammatory activity and mechanism of action of a hexane fraction (hWRF) obtained from white Rosa hybrida flowers by employing various assays such as quantitative real-time PCR, Western blotting, and Electrophoretic-Mobility Shift Assay (EMSA). The results revealed that the hWRF had excellent anti-inflammatory potency by reducing inflammatory repertoires, such as inducible nitric oxide synthase (iNOS), interleukin-$1{\beta}$, and cyclooxygenase-2 (COX-2) in RAW264.7 cells when stimulated with lipopolysaccharide (LPS), a pro-inflammatory mediator. The reduction of nitric oxide (NO) release from RAW 264.7 cells supported the anti-inflammatory effect of hWRF. Interestingly, hWRF effectively inhibited LPS-mediated nuclear factor-${\kappa}B$ (NF-${\kappa}B$) p65 subunit translocation into the nucleus and extracellular signal-regulated kinase (ERK)1/2 phosphorylation, suggesting that hWRF anti-inflammatory activity may be based on inhibition of the NF-${\kappa}B$ and MAPK pathways. Based on the findings described in this study, hWRF holds promise for use as a potential anti-inflammatory agent for either therapeutic or functional adjuvant purposes.
