This research was designed to evaluate the possible anti-inflammatory effects of Carex scabrifolia Steud. extract using RAW264.7 cells. The assessments of these effects were based on cell viability assay, mRNA expression levels of interleukin-1 alpha (IL-1α), interleukin-1 beta (IL-1β), IL-6, tumor necrosis factor alpha (TNFα), and levels of nitric oxide (NO)/prostaglandin E2 (PGE₂) production. Quantitative real-time polymerase chain reaction showed that treatment with C. scabrifolia Steud. extract decreased the mRNA levels of iNOS, COX2, IL-1α, IL-1β, IL-6, and TNFα. Furthermore, from the production levels of PGE₂/NO, it can be inferred that C. scabrifolia Steud. extract exhibited anti-inflammatory properties. These results suggest that C. scabrifolia Steud. extract contains anti-inflammatory compound(s), and consequently, that it may have applications as a potent cosmeceutical material.

본 연구는 2006년 7월부터 2008년 4월까지 한국 서남해안의 대표적인 18개 해안 염습지에서 생육지와 토양특성을 조사하여 서남해안 염습지 식생복원을 위한 기초자료를 제시하였다. 조사지역은 염습지의 생육지 유형에 따라 1차적으로 해안성 염습지와 하구성 염습지로 구분하고, 2차적으로 해안성 염습지는 점토성 염습지, 사질성 염습지, 사구성 염습지, 하구성 염습지는 염소택지와 기수성 염습지로 구분하였다. 생육지 유형별 주요 식물군락은 점토성 염습지에서는 갈대군락, 천일사초군락, 칠면초군락, 사질성 염습지에서는 갈대군락, 갯잔디군락, 천일사초군락, 퉁퉁마디군락, 큰비쑥군락, 해홍나물군락, 사구성 염습지에서는 갯그령군락, 통보리사초군락, 순비기나무군락, 염소택지에서는 갈대군락, 갯잔디군락, 해홍나물군락, 천일사초군락, 하구 염습지에서는 칠면초군락, 갈대군락, 천일사초군락, 나문재군락으로 나타났다. 염생식물 군락분포지역의 토양 환경은 염생식물의 생육지 특성에 따른 염생식물군락과 토양의 차이가 나타났다. 따라서 해안 염습지를 복원할 경우, 염습지를 대상으로 생육지 토양의 물리적 특성, 이화학적특성을 파악하여 생육지 조건에 맞는 염생식물을 선정하고, 이식한 후 자연식생이 형성된 지역을 중심으로 점차 확장시킴으로써 염생식물이 안정적으로 정착, 발아, 생장하는데 유리할 것이다.

To investigate the solute pattern of salt marsh plants in Suncheon Bay in Korea, plants and soil samples were collected at three sites from July to September 2011. The soil pH around the investigated species was weakly alkaline, 6.9-8.1. The total ion and Cl- content of site 1 gradually increased, while those of site 2 and site 3 were lowest in August and highest in September. The exchangeable $Ca^{2+}$, $Mg^{2+}$ and $K^+$ in the soil were relatively constant during the study period, but the soil exchangeable $Na^+$ content was variable. Carex scabrifolia and Phragmites communis had constant leaf water content and very high concentrations of soluble carbohydrates during the study period. However, Suaeda malacosperma and S. japonica had high leaf water content and constant very low soluble carbohydrate concentrations. Carex scabrifolia accumulated similar amounts of $Na^+$ and $K^+$ ions in its leaves. Phragmites communis contained a high concentration of $K^+$ ions. Suada japonica and S. malacosperma had more $Na^+$ and $Cl^-$ ions than $K^+$ ions in their leaves. Suaeda japonica had higher levels of glycine betaine in its leaves under saline conditions than C. scabrifolia and P. communis. Consequently, the physiological characteristics of salt marsh chenopodiaceous plants (S. japonica and S. malacosperma) were the high storage capacity for inorganic ions (especially alkali cations and chloride) and accumulation of glycine betaine, but monocotyledonous plant species (C. scabrifolia and P. communis) showed high $K^+$concentrations, efficient regulation of ionic uptake, and accumulation of soluble carbohydrates. These characteristics might enable salt marsh plants to grow in saline habitats.

순천만에 자생하는 2종의 염생식물의 뿌리로부터 내생 진균을 분리하였다. 사용 되어진 염생식물은 칠면초와 천일사초이며, 스트렙토마이신이 포함된 최소배지를 사용하여 내생진균을 배양한 후 순수 분리하였다. 분리된 15 내 생진균 균주 rDNA의 ITS 영역의 염기서열을 분석한 결과 칠면초에서 5속, 천일사초에서 7속의 내생진균이 확인되었다. 그리고 Shannon's diversity index(H')를 이용하여 칠면초와 천일사초로부터 분리된 내생진균들의 종 다양성은 각각 1.561과 1.889로 확인되었으며 유연관계를 확인하기 위하여 계통분석을 수행하였다. 순천만 자생식물인 칠면초와 천일사초의 내생진균에서 자낭균문 Pezizomycotina 아문이 많이 분포하고 있음을 알 수 있었으며, Pezizomycotina 아문 중에서도 Sordariomycetes 강, Dothideomycetes 강, Eurotiomycetes 강에 속하는 내생진균이 칠면초와 천일사초에 모두 분포는 것을 확인하였다.

Daehuksan Island (125°23'-125° 28' E and 34°37'-34°42' N, ca 19.7㎢) in the southwestern part of Mokpo, Korea, is a part of the Dadohae National Marine Park. Most of the actual vegetation of the island is substitutional vegetation under various human impact such as grazing, cutting for firewood. And natural vegetation is partially distributed in the tutelary shrine forests, deep valleys, etc. During 1987, phytosociological investigation of this was carried out on the basis of Braum-Blanguet's method. The forest vegetation was classified into 1 association and 7 communities, Camellia japonica, Machilus thunbergii, Ardisio-Castanopsietum sieboldii, Daphniphyllum macropodum-Quercus acuta, Pyrrosia lingua-Pinus densiflora. Rhododendron mucronulatum-Pinus thunbergii, Carpinus coreana, and Psedosasa japonica community. Grassland vegetation was classified into Gleichenia japonica, Gleichenia dichotoma, Arundinella hirta-Miscanthus sinensis, Artemisia princeps var. orientalis. Imperata cylindrica var. koenii Artemisia princeps var. orientalis-Pennisetum alpecuroides, Carex boottiana, and salt marsh vegetation. Thypa orientalis, Spergularia marina, Phragmites communis, Carex scabrifolia, and Triglochin maritimum community. Based on them, the actual vegetation map was made in 1:50,000 scale.

Net production, dead material increments were measured, and annual respiration loss was simulated through a year to determine the gross production at the Phragmites longivalvis, Carex scabrifolia and Zoysia sinica stand on Okryudeung, a sand bar of the Nagdong river estuary. The maximum live biomass for above-ground organs of the three stands occured in October, i.e., 1, 985, 744 and 1, 013g/m2, and belowground net productions were estimated to be 650, 440 and 412g/m2, respectively. Materials died or shedding from live aboveground organs during the growth season were estimated to be 167, 81 and 0 g/$m^2$. From the results of simulation, annual variation of respiratiion was primarily dependent on the annual variation of temperature through a year. For annual respiration loss in three stands, 21.893, 6.147 and 5.036kg $CO_2/m^2$ were calculated, respectively. Corresponding gross productions were 72, 203, 22, 109 and 19, 909kcal/$m^2$. Respiration of belowground organs corresponded to 65%, 66% and 37% of the total plant respiration, and annual respiration loss accounted for 85%, 78% and 71% of the annual gross production. In view of efficiency of solar energy utilization, 5.8%, 1.8% and 1.6% of incident light energy were converted to gross production of plants during a year. With incident light energy during the growth season from April to September, energy utilizations for net production were estimated to be 1.2%, 0.4% and 0.6% at the three stands.

낙동강 하구 옥류등에 형성되어 있는 갈대, 천일사초 및 갯잔디 군락의 실소와 린의 동태를 조사하였다. 실소와 린의 흡수량 및 현존량은 식물군락의 물질생산과 단위 무게당 이들 무기영양소의 함량이 달랐다. 실소의 연 흡수량은 갈대, 천일사초, 갯잔디 군락에서 각각 224, 111 그리고 156 kg/ha이었고, 린의 연 흡수량은 각각 22, 29 그리고 21 kg/ha이었다. 염습지의 관속식물 군집은 다량의 질소와 인을 흡수하기 때문에 연안수의 당영양화를 일시적으로 경감시키는 역할을 할 수 있는 것으로 생각되었다.

For providing basic data on estuary conservation and pattern of vegetation succession of sand bar, the flora of delta was investigated from March 2004 to August 2006 in the Nakdong River estuary of Korea. The flora in the eight surveyed areas was composed of total 159 taxa that belonged to 46 families, 123 genera, 133 species, 1 subspecies, 20 varieties, and 5 forms. Among them, naturalized plants and evergreen broad trees were 31 taxa and 5 taxa, respectively. The communities of main species at delta of estuary were composed of 16 species such as Rosa rugusa community, Scirpus triqueter community, Phragmites communis community, Carex kobomugi community, Digitaria ciliaris community. Especially, Rosa rugusa community which are important to establish the southern limit line of distribution as the northern factor was distributed through Jinwoodo. The succession of main vegetation community in the new delta (Doyodeung) was in order of Carex scabrifolia, Scirpus triqueter, Phragmites communis, Imperata cylindrica var. koenigii and Miscanthus sinensis var. purpurascens. Therefore, the succession order of the surveyed area seems to predict the pattern of the vegetation succession of another deltas in Nakdong River estuary.
