The vascular plant species in the areas of Gonamsan and Shiribong in the Baekdudaegan were summarized as 295 texa: 89 families, 193 genus, 245 species, 44 varieties and 6 forms.10 taxa were recorded in the surveyed areas as the Korean endemic plants: Hosta capitat (Liliacease), Polygonatum lasianthum var. corenum (Liliaceae), Chloranthus japonicus (Cloranthaceae), Salix hulteni (Salicaoeae), Clematis richotoma (Ranunculaceae), Spiraea prunifolia for. simpliciflora (Rosaceae), Vicia unijuga (Fabaceae), Viola albida (Violaceae), cornus walter(Cornaceae), Weigela subsessilis (Caprifoliaceae).According to the list of Korean rare and endangered plants complied in the studied areas:Iris ensata var. spoyanea(Iridaceae), Viola albida (Vioaceae) and Aristolochia contorta (aristolochiaceae) Due to the rapid destruction and increase of visitors and the studied areas are located close to the villages, the naturalized plant species in the areas were more frequently appeared than the rare and endangered plant species.

Atherosclerosis is a progressive disease characterized by the accumulation of lipids and fibrous elements in the arteries. Monocytes/macrophages are involved in many aspects of the development of atheroscleotic plaques. It is known that the intercellular adhesion molecule-1 (ICAM-1) expressed preferentially on endothelial cells of atheroscleotic plaque. promotes local adhesion and transendothelial migration of monocytes, neutrophils. and lymphocytes. Using the human promyelocytic leukemia HL-60 cell line, we investigated the inhibitory effects of methoanol extracts of 175 plants on ICAM-1/LFA-1 mediated cell adhesion. Eight kinds of methanol extracts of tested plants inhibited PMA-induced homotypic aggregated cell adhesion. Eight kinds of methanol extracts of tested plants inhibited PMA-induced homotypic aggregation of HL-60 cells without cytotoxicity at the concentration of 6.25 ${\mu}$g/ml. $CHCl_3$ extracts (1.0 ${\mu}$g/ml) of Saururus chinensis and Chloranthus japonicus significantly inhibited agregation of HL-60 cells without cytoxicity.

This study investigated in the vascular plants of special protection zones (the native land of Berchemia berchemiaefolia in Sadam-ri and Gallon valley) of Songnisan National Park and identified the whole vascular plants. The numbers of vascular plants were summarized as 273 taxa including 82 families, 182 genera, 236 species, 3 subspecies, 28 varieties and 6 forms. Woody plants were identified as 124 taxa (45.4%) and herbaceous plants as 149 taxa (54.6%). A total of 107 taxa were identified in the area of Sadam-ri, and 246 taxa were found in the Gallon valley. A total of 8 taxa of rare plants were identified, each of which was divided into 1 taxa of endangered (EN; Daphne pseudomezereum var. koreana), 3 taxa of vulnerable (VU; Paeonia japonica, Berchemia berchemiaefolia and Iris minutiaurea), 3 taxa of least concern (LC; Aristolochia contorta, Syringa patula var. kamibayshii and Goodyera schlechtendaliana) and 1 taxa of data deficient (DD; Alangium platanifolium). The Korean endemic plants were 9 taxa (Clematis trichotoma, Thalictrum actaefolium var. brevistylum, Aster koraiensis, Cirsium setidens, etc.). In the specific plants by floristic region were 34 taxa, a degree I were 17 taxa (Chloranthus japonicus, Celastrus stephanotifolius, etc.), 9 taxa of a degree II (Euonymus pauciflorus, Acer triflorum, etc.), 4 taxa of a degree III (Aconitum longecassidatum, Angelica gigas, etc.), 2 taxa of a degree IV (Ulmus macrocarpa and Daphne pseudomezereum var. koreana), 2 taxa of a degree V (Berchemia berchemiaefolia and Alangium platanifolium). The naturalized plants were 5 taxa including Fallopia dumetorum, Trifolium repens, Ailanthus altissima, Oenothera biennis, Erigeron annuus. Naturalization rate (NR) was 1.8% of all 273 taxa of vascular plants and the invasive alien plants were not found. The purpose of this study is to identify the flora that grows in the special protection zones of Songnisan National Park and provide the basic data for the management of the special protection zone in the future.

In recent years, the view centered conservation for eco-system is getting important rather than development from human oriented perspective. As a result, the concept "Sustainable development", that is seeking harmony between conservation and development, appeared so that we researched distribution and status of vascular plants a site of project in the Bukkyungnam substation. The main findings from the study is as follows. The vascular plants a site of project in the Bukkyungnam substation area was listed 435 taxa; 93 families, 269 genera, 377 species, 1 subspecies, 51 varieties and 6 forms. Specific plant species by floral region were total 25 taxa; Acer palmatum (Planted species), Asperula lasiantha in Class III, Caryopteris incana, Cirsium schantarense in Class II, 21 taxa (Dryopteris erythrosora, Chloranthus japonicus, Salix glandulosa, Alnus hirsuta, Quercus variabilis, Ulmus parvifolia, Clematis patens, Rubus hirsutus, Euphorbia pekinensis, Cayratia japonica, Grewia biloba var. parviflora, Vaccinium oldhami, Microstegium japonicum, Hosta capitata, Polygonatum falcatum, etc.) in Class I. Based on the list of Korean endemic plants, 10 taxa were recorded; Cephalotaxus koreana, Populus tomentiglandulosa (Planted species), Indigofera koreana, Forsythia koreana (Planted species), Paulownia coreana (Planted species), Asperula lasiantha, Weigela subsessilis, Adenophora triphylla var. hirsuta, Carex okamotoi, Lilium amabile and based on the list of the rare plants by the Forest ResearchInstitute, 2 taxa were recorded in the studied areas; Lilium callosum (Preservation priority order; No. 191), Aristolochia contorta (No. 151).

Atherosclerosis is a progressive disease characterized by the accumulation of lipids and fibrous elements in the arteries. Monocyter/macrophages are involved in many aspects of the development of atherosclerotic plaques. It is known that the intercellular adhesion molecule-1(ICAM-1) expressed preferentially on endothelial cells of atherosclerotic plaque, promotes local adhesion and transendothelial migration of monocytes, neutrophils, and lymphocytes. Using the human promyelocytic leukemia HL-60 cell line, we investigated the inhibitory effects of methanol extracts of 175 natural plants on ICAM-1/LFA-1 mediated cell adhesion. Eight kinds of methanol extracts of tested plants inhibited PMA-induces homotypic aggregationof HL-60 cells without cytotoxicity at the concentration of $6.25\;{\mu}g/ml$. They were divided two fractions of $CHCI_3$ and $H_2O$ to use solvent partition. Among them, $CHCI_3$ extract $(1.0\;{\mu}g/ml)$ of Saururus chinensis and Chloranthus japonicus singificantly inhibited aggregation of HL-60 cells without cytotoxicity, respectively.

Acne is a chronic inflammatory follicular disorder of the skin, occurring in specialized pilosebaceous units on the face, and Propionibacterium acnes, a strict anaerobic pathogen, plays an important role in the pathogenesis of acne. To develop a reliable and effective anti-acne agent, we have evaluated antibacterial activity of 500 plant extracts, prepared from 335 plants, against P. acnes. Based on the results of disc-paper method, 25 plant extracts, including the extracts of Chloranthus japonicus (aerial part), Sophora flavescens (radix), Evodia officinalis (fructus), Ginko biloba (semem), Morus alba (root bark), Aralia continentalis (whole) and Reynoutria elliptica (radix), were selected as possible sources of anti-acne agent. Among them, the extract of S. flavescens (radix) was finally selected and kuraridin and kurarinone were identified as major active compounds of S. flavescens. These results suggested that medicinal and wild plants could be the potential source of anti-acne agent.
