  • Ethanol extracts from 36 vegetable samples were assayed for their growth-promoting effects on Bifidobacterium bifidum, B. longum, and Lactobacillus casei The growth-promoting effects varied according to bacterial strain and vegetable species. In modified Gy rgy broth, extracts of Lactuca sativa, Lycopersicon esculentum and L escutentum var. cerasiforme exhibited strong growth-promoting responses toward B. longum, and significant and strong growth- promoting response toward B. bifidum was observed in extracts of Actinidia arguta, Allium cepa, A. sativum, Brassica campestris subsp. napus vats. pekinensis, Capsicum frutescens, Daucus carota var. sativa, L sativa, 1. esculentum and L. esculentum var. cerasforme, Nelumbo nucifera, Cucurbita moschata, Lackca sativa var. capitata, and Rubus coreanus. For L casei, extracts of A. fshlosum, A. hberosum, Cichorium intbus, Cucurbita moschat\ulcorner Ipomoea batatas, 1. sativa var. capitata, L. esculentum, P. brachycarpa, Raphanus sativus, R. coreanus, and S. melongena strongly enhanced the growth of this bacteria. In modified Gy rgy broth, the promoting effect was most pronounced with B. bifidum and L. casei among lactic acid bacteria used. In MRS broth, A. arguta, A. cepa, A. sativum, B. campestris subsp. napus var. pekinensis, C. frutescens, and D. carota var. sativa L. satiw var. capitata, and R. coreanus strongly enhanced the growth of B. bifidum, Growth of B. longum was strongly affected by the addition of extracts from L. sativa var. capitata. For L casei, moderate growth-promoting responses were observed in 9 vegetable extracts. The promoting effect in MRS broth was most pronounced with B. bifidum among lactic acid bacteria used.

  • Anthracnose occurred on rapsberry grown in Gochang areas of Korea in 2003. The disease incidence was ranged from 1.1 to 2.6%. Anthracnose of rapsberry appeared as dark brown circular spots on naturally infected stems. The symptoms of infected stems were small brown to dark brown spots and gradually enlarged larger cylindrical dark brown lesions. The causal fungus of anthracnose isolated from the diseased plants was identifed as Colletotrichum coccodes based on the morphological and cultural characteristics. All isolates of C. coccodes were produced similar symptoms on the host leaves by artificial inocultion.

  • Antioxidant activity of factory eel teriyaki sauce with bokbunja was investigated by functional analysis. Sugar content analysis of eel teriyaki sauce-free with bokbunja showed fructose and glucose but not maltose. Anthocyanin content of eel teriyaki sauce with bokbunja juice concentrate was 40%. DPPH radical scavenging activity and total polyphenol content of bokbunja added eel teriyaki sauce increased with increasing amount of bokbunja and were 80% higher than control sample. Total polyphenol content and DPPH radical scavenging activity were closely related to electron donating ability. The preferred concentrations of eel teriyaki sauce for commercial production were 60% for bokbunja, 40% for bokbunja concentrate, 20% for bokbunja powder eel.

  • The aim of this study is to explore the potent phosphodiesterase 4 and 7 inhibitor from various herbal medicines for atopy treatment. In this study, 51 kinds of each herbal medicine, which were extracted with ethanol, was carried out the screening of PDE 4 and 7 inhibition using enzyme inhibitory assay. Of these, 8 species of herbal medicines, Rubus coreanus, Duchesnea chrysantha, Alisma orientale, Rehmannia glutinosa, Angelica dahurica, Thuja orientalis, Astragalus membranaceus and Perilla frutescens were screened as potential inhibitor against PDE 4 and 7. Among 8 species, Duchesnea chrysantha showed poteinial anti-atopic effect on DNCB-induced atopic model. Duchesnea chrysantha extract decreased serum IgE and histamine release significantly.

  • 복분자딸기에서 차응애에 대한 경제적피해수준과 요방제수준을 평가하였다. 2008년 5월 7일 접종밀도(성충 0, 5, 10, 20, 40마리/주)에 따른 시기별 발생밀도는 무접종구를 제외하고는 6월 상순까지 점점 증가하다가 이후 감소하는 경향이었고, 접종밀도가 높을수록 더 크게 증가하였다. 차응애 접종밀도에 따른 수량은 접종밀도가 높을수록 감소하였고, 그에 따른 수량감소율은 접종밀도가 높아짐에 따라서 증가하였으며, 2009년 5월 8일 접종밀도(성충 0, 2, 5, 10, 20마리/주)에 따른 시기별 발생밀도와 수량 및 수량감소율도 2008년과 유사한 경향이었다. 차응애 접종밀도와 수량감소율과의 관계를 회귀식을 이용하여 분석한 결과는 2008년 Y = 0.6545X + 3.0425 ($R^2$ = 0.93), 2009년 Y = 0.9031X + 2.0899($R^2$ = 0.96)의 관계식을 얻을 수 있었다. 차응애 접종밀도별 수량감소율과의 관계식에 근거하여 GT값이 전체수량의 5%되는 수량감소율 (Y)을 추정해 보았을 때 복분자딸기에서 경제적피해수준(X)은 2008년 3.0마리/줄기, 2009년 3.2마리/줄기이었고, 요방제수준은 각각 2.4마리/줄기, 2.6마리/줄기이었다. 접종밀도와 방제적기로 고려되는 5월 중순 차응애 발생밀도와의 관계는 2008년 Y = 0.471X + 2.495($R^2$ = 0.95), 2009년 Y = 0.9938X + 3.1858($R^2$ = 0.96)로 회귀식이 성립되었으며, 회귀식에 의하면 복분자딸기 차응애 요방제수준(2008년 2.4마리/주, 2009년 2.6마리/주)에 따른 5월 중순 발생밀도는 각각 2008년 3.6마리/엽, 2009년 5.8마리/엽이었다.
