Antifibrotic drugs could be delayed or inhibited massive collagen deposition in liver tissue or inhibited collagen synthesis. we investigated antifibrotic effects by several herbs(Schisnadra chinensis, Ganoderma japonicum, Sedum sarmentosum, Alisma canaliculatum, Plantago asiatica) extract with observations of collagen accumulation in liver tissue and collagen synthesis in sera. Rats were used for experimental animal that were devided 3 groups(sham control, BDL/S, BDL/S-ER). Rats were operated for inducing liver fibrosis(cirrhosis) by bile duct obstruction. Several herbs were prepared by water extraction and were applicated p. o. $3ml/day$ during 4 weeks. After observation period, rats were sacrificed and liver tissue and sera were collected. In result, the mortality of rats was 35% in BDL/S group and 20% in BDL/S-ER The color of bile juice in BDL/S-ER was bright yellow and murky yellow in BDL/S group. The significantly lower weight of liver($16.21g{\pm}5.3,\;20.58{\pm}2.4$) and spleen($1.96g{\pm}0.96,\;3.93{\pm}0.21$) were shown in BDL/S-ER than that of BDL/S(p<0.05) group. The value of collagen in liver tissue(25.7%) in BDL/S-ER was observed significantly lower than that of BDL/S group (Tab. 2). AST. ALT, ALP, t-bilirubin, BUN levels were low in BDL/S-ER as compared with those of BDL/S group, but the significance was not proven. The trichrome stained liver tissue in BDL/S-ER group was observed mild bile duct proliferation and fibrosis compared with BDL/S group. In conclusion, natural products inhibited new collagen synthesis and delayed massive collagen deposition in liver tissue, so that they have noticeable antifibrotic effects in experimental liver fibrosis(cirrhosis).

This study was performed to investigate the antioxidative effect as the inhibition of MDA and BSA conjugation reaction, inhibition of lipid peroxidation and the scavenging effect on DPPH radical, and antimutagenic capacities as the Ames test in 7 common vegetables taken by Korean for suggestion of prevention and dietetic treatment of chronic diseases and development of antioxidative and antimutagenic functional food. The water extracted fractions of perilla leaves were most effective in the inhibition of MDA and BSA conjugation reaction showing 77.2% of inhibition rate among 7 vegetables. The inhibition rates of ethanol extracted fractions of sedum and wild water dropwort on the lipid peroxidation were 67.1% and 61.5%, respectively. The ethanol extracted fractions of crown daisy and wild water dropwort showed the most effective results among 7 vegetables in the DPPH radical scavenging capacities showing inhibition rate of 78.8% and 73.6%, respectively. The indirect and direct antimutagenic effects of ethanol extract of 7 vegetables were examined by Ames test using Salmonella typimurium TA98 and TA100. Inhibitory effects of wild water dropwort was superior to the other vegetables on the Ames test. These results suggest that common 7 vegetables taken by Korean are believed to be a possible antioxidative and antimutagenic capacities, although the resultswere different, some or less, according to the assay method and vegetables used.

The walls of guard cells have many specialized features. Guard cells are present in the leaves of bryophytes, ferns, and almost all vascular plants. However, they exhibit considerable morphological diversities. There are two types of guard cells: the first type is found in a few monocots, such as palms and corn, and the other is found in most dicots, many monocots, mosses, ferns, and gymnosperms. In corns, guard cells have a characteristic dumbbell shape with bulbous ends. Most dicot and monocot species have kidney-shaped guard cells that have an elliptical contour with a pore at its center. Although subsidiary cells are common in species with kidney-shaped stomata, they are almost always absent in most of the other plants. In this study, there were many different stomatal features that were associated with kidney-shaped guard cells, but not dumbbell shaped guard cells, which are present in most grasses, such as cereals. Each plant investigated exhibited different characteristic features and most of these plants had kidney-shaped guard cells. However, the guard cells of Chamaesyce supina Mold, were often more rectangular than kidney-shaped. In contrast, Sedum sarmentosum guard cells were of the sink ensiform type and in Trifolium repens, the guard cells exhibited a more rhombic shape. Therefore, kidney-shaped guard cells could be divided into a number of subtypes that need to be investigated further.

The study was conducted to present the criteria of plant selection and planting design pattern suitable for the vegetation blocks which are becoming more popular for the facade greenery in urban areas. The main results are summarized as follows. 1. Under irrigated conditions, the plant grew better than that of unirrigated conditions and herbs grew better than shrubs. In selection of shrubs, it would be more proper to consider the size and depth of the pockets. 2. Under unirrigated conditions, Sedum middendorffianum and foreign sedums grew well, so it can be concluded that sedums can grow at low management condition. And, Hosta longipes and Aceriphyllum rossii could be survive at low management conditions only if irrigation was conducted at dry season. But, shrubs needed irrigation management for survival at vegetation blocks. 3. The results of this study, it can be concluded that greenery of walls and retaining walls might be effective for the creation of green space, improvement of urban landscapes, and the creation of diverse biotopes in urban areas with vegetation blocks.

This study aimed to understand whether the geo-ecological segregation of native plant species affects the root-associated fungal community. Rhizoplane (RP) and rhizosphere (RS) fungal microbiota of Sedum takesimense native to three geographically segregated coastal regions (volcanic ocean islands) were analyzed using culture-independent methods: 568,507 quality sequences, 1399 operational taxonomic units, five phyla, and 181 genera were obtained. Across all regions, significant differences in the phyla distribution and ratio were confirmed. The Chao's richness value was greater for RS than for RP, and this variance coincided with the number of genera. In contrast, the dominance of specific genera in the RS (Simpson value) was lower than the RP at all sites. The taxonomic identity of most fungal species (95%) closely interacting with the common host plant was different. Meanwhile, a considerable number of RP only residing fungal genera were thought to have close interdependency on their host halophyte. Among these, Metarhizium was the sole genus common to all sites. These suggest that the relationship between potential symbiotic fungi and their host halophyte species evolved with a regional dependency, in the same halophyte species, and of the same natural habitat (volcanic islands); further, the fungal community differenced in distinct geographical regions. Importantly, geographical segregation should be accounted for in national culture collections, based on taxonomical uniqueness.

Significant efforts are being devoted in mitigating the urban heat island effect, and extensive green roofs are an option for mitigation. The purpose of this study was to compare the surface temperature, vegetation types, and plant species on an extensive green roof. Test beds were created in May 2015, and the surface temperature was monitored from June to August. The test beds comprised polyculture and monoculture. Polyculture was divided into three types, and monoculture comprised eight plant species. An extensive green roof is effective in reducing temperature by forming a shade and preventing sunlight from falling on the surface of buildings, which mitigates the urban heat island effect. Consequently, the surface temperature of the green roof and that of concrete during summer reduced from $17.8^{\circ}C$ to $7.3^{\circ}C$. The temperature reduction was greater on using polyculture than on using monoculture, but monocultures of Sedum takesimense, Hemerocallis dumortieri, Allium senescens, Aster yomena, Belamcanda chinensis, and Aster koraiensis also produced good results. The temperature reduction effects of Polygonatum odoratum var. pluriflorum f. variegatum, Phlox subulata, and Thymus quinquecostatus var. japonica were excellent compared with those of concrete but were less than those of other plant species. Careful attention is needed for the management of extensive green roofs. Studies on the plant species and types of extensive green roof should continue to mitigate the urban heat island effect.
