widely used as an anti-wrinkle agent in anti-aging cosmeceuticals. PMP/PNP were prepared with an ionotropic gelation method, and anti-oxidative activity of the particles was measured with a DPPH assay. The stability of RP in the particles along with pectin gel and ethanolic solution was then evaluated. In vitro release and skin permeation studies were performed using Franz diffusion cells. Distribution of RP in each skin tissue (stratum corneum, epidermis, and dermis) was also determined. PMP an... -

addition of pectin improved the stability of RP in a concentration dependent manner. The stabilizing effect of pectin on RP was more effective for the lower concentration of RP (0.01%, v/v). Further, degradation of RP was reduced following the addition of pectin as measured over 8 hours. From the results obtained, it can be suggested that pectin may be a promising ingredient for cosmeceutical bases designed to stabilize RP or other pharmacological agents subject to degradation by oxidation. -

7.90 uints/mg protein으로 나타났으나 exo-type의 효소보다는 그 활성이 낮았다. 수용성 pectin은 부패가 진행됨에 따라 14일째에 11.50 mg/100 mg-AIS이었고, versene-soluble pectin 역시 7.31 mg/100 mg-AIS로 나타나 건전과와 비교하여 각각 4.23 및 2.16 mg/100 mg-AIS 증가하였다. 부패과의 총 가용성 펙틴 함량은 총 pectin의 72.4%로서 건전과와 비교하여 24.8% 더 높았다. 불용성 pectin 함량은 부패가 진행됨에 따라 15.32 mg/100 mg-AIS에서 7.16 mg/100 mg-AIS로 현저하게 감소하였으며, 총 pectin 함량은 큰 변화가 없었다. -

사과겹무늬썩음병균 Botryosphaeria dothidea를 pectin-polypectate 배지(培地)와 사과배지(培地)에 배양(培養)하여 pectin질(質) 분해효소(分解酵素)의 생산(生産)과 활성(活性)을 조사하였다. exo-polygalacturonase와 exo-polymethylgalacturonase의 활성은 사과배지에서 배양 6일에 각각 6.4 와 7.2 units로 최대의 활성을 나타내었고, 인공배지에서는 배양 8일에 각각 5.9 와 5.3 units 의 활성을 나타내었으나 사과배지에 비해 낮았다. endo-polygalactu-ronase와 endo- polymethylgalacturonase는 인공배지에서 각각 4.4 와 16.2... -

The type III secretion system (T3SS) is a key virulence determinant in the infection process of Pseudomonas syringae pv. tomato DC3000 (Pst DC3000). Pathogen constructs a type III apparatus to translocate effector proteins into host cells, which have various roles in pathogenesis. 4-Hydroxybenozic acid and vanillic acid were identified from root extract of Sedum middendorffianum to have inhibitory effect on promoter activity of hrpA gene encoding the structural protein of the T3SS apparatus. The... -

Some species of the Trichoderma genus are reported as the major problem in oak wood mushroom production in Korea. In spite of economic loss by the fungi, scientific information on airborne Trichoderma species is not much available. To generate information for disease management development we analyzed airborne Trichoderma. A total of 1,063 fungal isolates were purely obtained from indoor air sampling of cultivation houses used for oak wood mushroom using sawdust media. Among the obtained...
