These days, the raw materials that have the cell recovering effect are used commonly in cosmetics. In this study, six materials were rested for the characteristics of recovering effect both on vivo and in vitro. Tested raw materials were Soypol, 3-APPA, Apple extract, Polygonatum japonicum extract, Scutellarkd baicalensis extract, Aloe extract. Among these materials, Soypol and 3-APPA were synthesized and others were made by extraction at the Pacific R&D Center. Human forearm skin and cultured skin cell were damaged by sodium lauryl sulfare and then raw materials were applied for open treatment on SLS damaged human skin or cells. The recovering effects of raw materials in vivo were evaluated by measuring transepidermal water loss, skin hydration and erythema and in vitro effects of proliferationg cells were assessed by neutral red uptake assay. In the in vivo study, only the evaluation by TEWL showed correlation with the visual score. Our of six materials, 3-APPA had the most positive effect in both in vivo and in vitro studies and the correlation was r=0.8286 (p=0.042).

Adequate regrowth control of weeds and shrubs has been one of the important problem for pasture establishment by overseeding on reclaimed forest hilly land. This experiment was carried out on sloping shrub land near Anseong, Gyeonggido to evaluate the effects of herbicide application on growth control of native weeds, shrubs and trees. We evaluated 63 different weeds and wood species in the trials, which are grown common in korean forest. Buthidazol and 4 other herbicides (sodium chlorate, glyphosate, U-46 and gramoxone) were sprayed each at two application rates during the period of the most intensive growth, on 20 July 45 days before overseeding of pasture species. Glyphosate and sodium chlorate gave excellant control of growth of all species. However. Uncus effusus, Carex heterostachya, Polygonatum humile, Rubus corchorifolius, Lonicera coeralea and Rhododendron mucronulatum were classified as a tolerant weed and wood species to herbicides. Herbicide buthidazol showed also successive control of regrowth of weeds and wood species. But buthidazol was evaluated as a none available herbicide for use in pasture establishment. because o! their long persist of toxic herbicide residue in soils after treatments. Herbicide U-46 and gramoxone had almost no effect on regrowth of shrubs and tree species

The contents of total flavonoids, total antioxidant status and superoxide scavenger activity of edible plants were measured. Among twenty one samples of leafy vegetables and teas, mugwort (Artemesia capillaris) and green teas gave high total flavonoids contents, 48.2 mg/g sample and 44.7 mg/g sample, respectively. The highest concentration of total flavonoids among eighty nine samples analyzed was 52.1 mg/g sample from propolis. When samples were tested for total antioxidant status, a kind of groundsel showed the highest Total Antioxidant Status(TAS) value, 13.4 mM among leafy vegetables and teas and green tea gave high TAS value, 11.84 mM. On the other hand, purslane gave the lowest TAS value, 0.01 mM. The superoxide scavenge activity was measured from the extracts of all edible plants. The superoxide scavenge activity of polygonatum(81.1%) and chrysantemum (78.5%) were the highest among leafy vegetables, teas and medicinalplants. On the other hand, ginseng, poria, cassiae semen and dioscoreae rhizoma showed no superoxide scavenge activities.

PCBs 투여로 중독된 rat에 대한 천문동, 황정, 백복령, 인삼, 오가피 등의 ethanol 추출물의 효과는 다음과 같다. 1. 생약추출물의 병용투여로 PCBs 중독으로 감소된 체중이 증가하였으나 간장중량의 현저한 회복효과는 볼 수 없었다. 2. 생약추출물을 병용투여함으로써 PCBs 중독으로 감소된 RBC, WBC, Hgb 및 Het의 값이 상승하였으며 특히 백복령과 인삼 추출물의 경우 회복효과가 컸다. 3. PCBs로 증가된 혈청중 cholesterol치와 total lipids가 생약추출물을 투여함으로써 감소되었다. 4. PCBs 투여로 증가된 혈청중 GOT, GPT 및 ALP의 활성도 생약추출물의 투여로 정상치에 가깝게 감소되었다.

The prescriptions (DB-1-DB-5) were prepared with the active herbal medicines, Acanthopanax senticosus, Glycyrrhiza uralensis, Polygonatum odoratum, and Cichorium intybus. The most active crude polysaccharide fraction (DB-2-3), which was isolated through the fractionation of hot-water extract from DB-2, was significantly reduced by periodate oxidation (52.7 and 63.7%) on intestinal immune system modulating and anticancer activity. When DB-2-3 was further fractionated by column chromatographies, DB-2-3IIc-2 showed the most potent activities. In addition, DB-2-3IIc stimulated the proliferation of bone marrow cells via Peyer's patch in dose-dependent pattern by oral administration. The metastasis of colon 26-M3.1 lung carcinoma had significantly inhibited in mice fed DB-2-3IIc at 1 mg/mouse (43.8%). DB-2-3IIc-2 mainly contained uronic acid (46.1%) and 42.5% of neutral sugar with a small amount of protein (7.6%), and component sugar analysis also showed that DB-2-3IIc-2 was composed Ara, Gal, and GalA (molar ratio; 0.50:0.63:1.00). It may be suggested that activities of DB-2-3IIc-2 are resulted from pectic polysaccharides containing a polygalacturonan moiety with side chain of neutral sugars, such as Ara and Gal.

We have investigated the vegetation in the peninsula located in Ongjeong-Li Seomyeon in Youngweol-gun. Since this is a limestone area, boxtrees, Abelia mosanensis T. H. Chung ex Nakai, and Selaginella stauntoniana Spring were abundant, as these are types of vegetation characteristic of limestone areas. Pinus densiflora S. et Z. was the most dominant woody plant, but vegetational changes, such as the dominance of Quercus variabilis Blume, Quercus dentata Thunb, and Quercus mongolica Fischer, were observed in spots. In particular, the growth of nursery plants of pinus densiflora S. et Z. was not observed, and young trees like Quercus mongolica Fischer grow as low vegetation of Pinus densiflora S. et Z.. Thus, the ecological succession of Quercus mongolica Fischer is predicted. Outside the investigation area, as herbaceous plants, various vegetations were observed, including Selaginella stauntoniana Spring, Thalictrum coreanum H. Lev., Mukdenia rossii(Oliv.) Koidz., Platanthera freynii Kraenzl., Cephalanthera longibracteata Blume, Potentilla dickinsii Franch., Patrinia rupestris(Pall.) Juss., Swertia pseudochinensis H. Hara, Vicia venosa(Willd.) Maxim., Pyrola japonica Klenze ex Alef., Disporum smilacinum A. Gray, Artemisia stolonifera(Maxim.) Kom. for. Stolonifera, Smilax nipponica Miq., Adenophora triphylla var. japonica(Regel) H. Hara, Isodon inflexus(Thunb.) Kudo, Gentiana scabra Bunge for. Scabra, Polygonatum odoratum var. pluriflorum(Miq.) Ohwi, Dioscorea quinqueloba Thunb., Syneilesis palmata(Thunb.) Maxim., Asparagus schoberioides Kunth, Eupatorium japonicum Thunb. ex Murray, Galium kinuta Nakai & Hara, Saxifraga fortunei var. incisolobata, Lilium amabile Palib., Siberian iris, Dictamnus dasycarpus Turcz., Atractylodes ovata(Thunb.)
