The aim of this study was to investigate the antioxidant effect of medicinal plants used by diabetic patients. Fourteen medicinal plants were selected and antioxidant activity such as 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, inhibition effect of linoleic acid autoxidation and low density lipoprotein (LDL) oxidation, thiobarbituric acid (TBA) value were measured. The Cornus officinalis had DPPH radical scavenging activity of 84.79%, which was higher than the 78.79% for $\alpha$-tocopherol. Rosa rugosa Thunberg, Pueraria thundergiana Bentham, Artemisia princeps var. orientalis and Sasamorpha purpurascens Nakai also had high values. Extracts with higher DPPH radical scavenging activities had higher total phenol concentrations, and positive correlations between these parameters were found. Inhibitory activities of linoleic acid autoxidation, LDL oxidation and TBA value, used as indices of oxidative stress, were observed in most of the selected medicinal plants. The highest inhibitory activity for TBA value was observed in the extract of Pueraria thundergiana Bentham. Rosa rugosa Thunberg (75.50 %), Sasamorpha purpurascens Nakai (74.00 %), and Cornus officinalis (73.00 %) all had high antioxidant activity against linoleic acid autoxidation, similar to that of $\alpha$-tocopherol. The same 3 plants also had high in inhibitory activity against LDL oxidation. Therefore, we demonstrated that medicinal plants used as folk remedy by diabetic patients had antioxidant activity. Especially, Rosa rugosa Thunberg, Cornus officinalis, Pueraria thundergiana Bentham, Arlemisia princeps var. orientalis, and Sasamorpha purpurascens Nakai had high phenol concentrations which resulted in high values for DPPH radical scavenging. These same plants exhibited high values for inhibitory activities for TBA value, linoleic acid autoxidation and LDL oxidation, indices associated with lipid peroxidation.

Korean society is a mix of western and traditional cultures. Even though the patients try to recover through both aspects, hospital only utilizes a western approachs. When they have suffered from a chronic disease, especially diabeties meliitus(DM), application of folk medicine is more varied but the nurses are unaware of the practices. This study was done to describe the current use of the folk medicine with which the patients with DM have had an experience and to identify the relationships between the westernized medical care and folk medicine application. The 244 patients with non-insulin dependent diabetes millitus who participated were interviewed at a DM education clinic in a 1500-bed hospital. The results of the study are as follows: 1. 54.1%(N=133) of the participated patients in this study have had a folk medicine. 2. 44 kinds of folk medicine were used for the treatment of DM. Among them 14 items were used by more than two people and the rest were used by one person. Among the used items, 70.4% consisted of various types of plants, 11.4% was animal material and 18. 2% was the mixed group. As a single item, Commelina Communis(Dalgaebi) was the most frequently used(62.8%), followed by the root of Rosa rugosa(Haedangwha) 14.3%, and Youngi mushroom 13.6%. 3. In the analysis of the relationships between the general characters of the patients with regular fol1ow-up(F-U), self blood sugar test(BST) and folk medicine usage: 1) The higher the educational back ground patient had, the lower the folk medicine usage was ($X^2$=14.265, P=.003). 2) The more complex their treatment was($X^2$=24. 016. P=.000). and the longer they had suffered from DM($X^2$=75.739, P=.000), the fewer they visited regular F-U. On the other hand, they did self-BST well($X^2$=7.722, P=.021 : $X^2$=14. 775, P=.002) and had more folk medicine($X^2$=33.382, P=.000 ; $X^2$=43.410, P=.000). 3) If they had suffered many symptoms, they had fewer regular F-U ($X^2$=13.192. P=.001). On the other hand, they had more folk medicine($X^2$=6.070, P=.048). 4) The group of family history($X^2$=6.801. P=.009) and the group of DM education experience($X^2$=15.678, P=.000) carried out self BST well. DM education group used more folk medicine($X^2$=8.680, P=.003). In conclusion, DM education should be grouped according to the treatment type and suffering period. Then the management of DM would be effective and the vague application of folk medicine would be decreased.

This study was carried out to analyze distribution situation of alien plants and to propose management plan in the 3 Folk village in Gyeongsangbuk-do which is Cultural property designated by the State; Hahoe, Yangdong and Hangae. This research is for improve of sincerity of historical site and provide basic information which use about administration of preservation. The results are as follows. 1. Overall flora and alien plants appearance The total flora in the 3 folk villages were listed total 752 taxa including 127 families, 430 genera, 614 species, 5 subspecies, 100 varieties and 33 forms. Among them, woody plants take 263 taxa(35.0%) and herbaceous plants take 489 taxa (65.0%). Flora in the Hahoe, Yangdong and Hangae village were total 534, 479 taxa and 408 taxa and exotic plant index was 30.1%, 38.2% and 37.0% respectively. In types of exotic plants, ornamental exotic plants were 135 taxa, deciduous exotic plants were 21 taxa, cultivating exotic plants were 64 taxa, and naturalized exotic plants were 80 taxa and those result lead that the ornamental exotic plants is the highest ratio. According to the villages, Hahoe village had 161 taxa(30.1%), Yangdong Village had 183 taxa(38.2%), and Hangae village had 151 taxa(37.0%) that Yangdong village showed the most number of exotic plants. 2. Planting of landscape exotic plants in the unit cultural assets Meanwhile, Ornamental exotic plants in old house's gardens in Andong Hahoe village which is designated as a unit assets, those are total 30 taxa; followed by the Okyeon house(8 taxa) is highest and the Yangjindang(7), the Hadong house(6) and the Chunghyodang(5). Magnolia denudata appears the most as for 4 times and Campsis grandiflora etc. each took 2 times. Based on the Yangdong village, Gyeongju, that are found total 51 taxa; followed by the Dugok house(16 taxa) the Sujoldang(14), the Mucheondang(13), and the Sangchunheon (12). High appearance rate of ornamental exotic plants were Viburnum opulus for. hydrangeoides, Lycoris squamigera, Caragagna sinica and Magnolia denudata etc. Based on the Hangae village, Seongju, that are designated total 62 taxa; followed by the Jinsa house(35 taxa), the Gyori house(25), the Hanju head family house(20), and the Hahoe house(16). Taxa with high appearance rates were Caragana sinica, Juniperus chinensis var. horizontalis, Magnolia denudata, Viburnum opulus for. hydrangeoides, Chaenomeles speciosa etc. 3. Problems of exotic plant landscapes in the outer spaces of the folk villages Problems of exotic plant landscapes in the outer spaces of the Hahoe village are as follows. In lower of the Mansongjeong forest, Ambrosia artemisifolia, which are ecosystem disturbance plants designated by the Ministry of Environment, live with high dominance value. This should be have a remove with Sicyos angulatus immediately. In the Nakdong river bed around the Mansongjeong forest is covered with a riparian vegetation forest belt of Robinia pseudoacacia L. forest, Populus nigra var. italic community, and Populus x tomentiglandulosa community colony. Based on the Yangdong village, the planted or naturally distributed Ailanthus altissima colony, sporadically distributed Robinia pseudoacacia as well as Amorpha fruticosa are detected all over the village and ecotones. Based on the Hangae village, Ailanthus altissima and Robinia pseudoacacia are sporadically distributed around the village and there is a sign of spreading. similarity of exotic plantsis 47.0% to 48.6% and a reason why this happened is all of research site in Gyeongsanbuk-do and that is why growth norm of plant is similar, exotic plant which is sales for ornamental and it infer to require related countermeasure of each villages and joint related countermeasure.

We investigated the antioxidative and antimicrobial activities of the methanol extracts from Korean folk plants (MKs) in Chungcheong Province. Among 30 MKs, 16 plants at $100{\mu}g/ml$ showed over 90% scavenging activity of 1,1-diphenyl-2-picrylhydrazy (DPPH) and 30 plants exerted the hydroxyl radical scavenging effect over 55%. Fourteen plants at the concentration $50{\mu}g/30{\mu}l$ showed strong microbial inhibition activity against Escherichia coli and Staphylococcus aureus, with clear zone greater than 11 mm in disc assays. Furthermore, the protective effect against anti-inflammatory system using RAW 264.7 macrophage cell was also studied. The treatment of LPS & INF-${\gamma}$ to RAW 264.7 cell induced nitric oxide (NO), however inhibit the formation of NO less than 50% of 5 plants. The present result indicates that the 30 species of MKs exerts protective effect of oxidative stress, antimicrobial activities and anti-inflammatory. In particular, Rhus javanica and Cornus controversa showed stronger effect on not only radical scavenging activity and inhibits growth of S. aureus but also highest protective effects from inflammation.

Cupressaceae plants are used in traditional folk medicine. whose extracts have been found to possess some bioactivities. (－)-Yatein is a lignan of the dibenzyl-butyrolactone type. that has been isolated from some Cupressaceae plants. It was reported that (－)-yatein. isolated from plants. showed different activities from the synthetic yatein ［3］. Hence. the enantiosetective determination of yatein from synthetic materials and natural products would be necessary. (omitted)
