The leaf persisting and seasonal leaf color characteristics of deciduous woody landscape plants were investigated through the field survey in Suwon region. The leaf period was about 270 days from March 20, 1992 when Prunus padus was leaf spreading to December 17, 1992 when Lonicera sempervirens was leaf falling. The plants of leaf period over 240 days were Elaegagnus umbellata var. coreana, Salix pseudo-lasiogyn, Ligustrum obtusi-folium, Rosa multiflora, Lonicera sempervirens and Clematis viticella. The woody landscape plants bearing the red leaf by KBS standard color number before fall foliage coloring were Prunus salicina, Berberis thunbergii 'Atropurpurea', Acer platanoides 'Red King', Acer palmatum var. Pendula 'Crimson Queen', Parthenocissus tricuspidata, Nyssa sylvatica, Acer palmatum var. sanguineum, and the yellow leaf, Berberis thunbergii Variegata 'Aurea', Physocarpus opulifolius 'Luteus', and Forsythia koreana 'Seoul Cold', Ligustrum X vicaryi which is variegation. The fall foliage color period was about 100 days from September 6, 1992 when Euonymus alatus was fall foliage coloring, to December 17, 1992 when Lonicera sempervirens was leaf falling. (Table 24) And in terms of color based on KBS standard color number, 60.7% of fall foliage were yellow, 37.4%, red, respectively.

To investigate the structure and the conservation strategy of Korean native species, the Abies koreana forest at sub-alpine zone centering on the Witsaeorum(1,714m) shelter in Hallasan National Park was selected for a survey subject with 20 plots $(10{\times}10m)$ set up with random sampling method. Mean importance percent(MIP) of Abies koreana showed the highest numerical value-57.7%, and that of faxus cuspidata was the next value-16.2%. High positive correlations were shown between Taxus cuspidata and Prunus maximowiczii, Euonymus alatus; Betula ermani and Berberis amurensis var. quelpaertensis, Prunus sargentii; Prunus maximowiczii and Euonymus alatus; Berberis amurensis var. quelpaertensis and Prunus sargentii. Vigor of Abies koreana was so low that as much as 6.44% of total number of Abies Koreana investigated were dead. DBH of dead individuals ranged mainly from 5cm to 15cm.

Cotton fabric is usually dyed with anionic dyes such as direct and reactive dyes. Naturally, there is no affinity for basic dyes to cotton fiber. In this study, to improve the dyeability of cotton fiber with cationic dyes, the fabric was pretreated with air plasma and grafted with acrylic acid to create acidic groups on the surface of cotton fibers. The grafted samples were dyed with natural cationic dye extracted from roots of berberis vulgaris. The effect of plasma treatment and grafting of acrylic acid on the color strength of cotton fabric was studied.

This research carried out forest community classification on the basis of the methods of ZM school, in order to furnish useful information needed for forest management, and for afforestation and preservations of Abies koreana forest which was Korean native species, and the research results could be summarized as follows. Abies koreana forest was divided into 10 vegetation units ; This forest was divided into Abies koreana-Quercus mongolica community and Abies koreana-Sasa quelpartensis community. Abies koreana-Quercus mongolica community was divided into Tripterygium regelii group, Patrinia saniculaefolia group, and Typical group, and Tripterygium regelii group seas divided into Typical subgroup. Pimpinella brachycarpa subgroup, and Hemirocallis fulva subgroup. Abies koreana-Sasa quelpartensis community was divided into Berberis koreana group, Trachelospermum asiaticum var. intermedium group, and Typical group. Berberis koreana group was divided into Typical subgroup and Hepatica asiatica subgroup, and Tranchelospermum asiaticum var. intermedium group was divided into Hepatica asiatica subgroup and Typical subgroup. According to the results of the analysis by coincidence method, Abies koreana-Quercus mongolica community represented in Mt. Chiri, Mt. Deokyu and Mt. Kaya which were located in the Sobaek mountains, Abies koreana-Sasa quelpartensis community represented in Mt. Hanla. Therefore it was thought that Abies koreana forest was classified by geographical position, and vegetation units of Abies koreana forest tended to be classified by the altitude and topography. As for DBH and height of Abies koreana, mean DBH and height of Abies koreana-Quercus mongolica community were each 28.4cm, 10.6m that were larger than mean DBH and mean height(each 23.6cm, 6.3m) of Sasa quelpartensis community. Among Abies koreana-Quercus mongolica community, Patrinia saniculae-folia group had the smallest mean DBH and mean height(20cm, 5m), and among Abies koreana-Sasa quelpartensis community, Typical group had the smallest mean DBH and mean height(4cm, 3m).

Majarine that was isolated from Berberis Koreasra Palibin (Berberidaceae) is the isoquinoline alkaloid. The effects of dopaminergic and serotonergic antagonists on majarine induced changes in body temperature were studied in the mouse. Intraperitoneal administration of majarine produced dose-dependent hypothermia. At a dose of 0.1 mg/kg, majarine caused a slight increase in body temperature. Majarine-induced hyperthermia was attenuated by the 5-HT antagonist, cyproheptadine However, it caused hyothermia in mice pretreated with the DA antagonist, haloperidol, and hyperthermia in mice pretreated with haloperidol and cyproheptadine in comparision with haloperidol pretreatment. At a dose of 2.0 mg/kg, majarine-induced hypothermia was attenuated by haloperidol and cyproheptadine, respectively. In reserpine pretreated mice, majarine produced dose-dependent hypothermia. At a dose of 0.1 mg/kg, majarine pretreated with haloperidol caused no significant effect in body temperature. At a dose of 2.0 mg/kg, majarine-induced hypothermia was attenuated by haloperidol pretreatment in mice treated with reserpine and ${\alpha}$-methyl-p-tyrosine. These data suppose that both dopaminergic and serotonergic mechanisms in the brain mediate the effects of majarine on body temperature. We propose that majarine directly stimulate DA receptor, which secondarilly activate 5-HT neurons to cause changes in body temperature.

Objectives: Oxidative stress plays a key role in chronic and acute brain disorders and neuronal damage associated with Alzheimer disease (AD) and other neurodegeneration symptoms. The neuroprotective effects of berberine and Berberis vulgaris (barberry) root extract against apoptosis induced by hydrogen peroxide (H₂O₂) in the human SH-SY5Y cell line were studied. Methods: The methanolic extraction of barberry root was performed using a maceration procedure. Oxidative stress was induced in SH-SY5Y cells by H₂O₂, and an MTT assay was applied to evaluate the neuroprotective effects of berberine and barberry root extract. The cells were pretreated with the half maximal inhibitory concentration (IC₅₀) of each compound (including berberine, barberry root extract, and H₂O₂), and the anti-apoptotic effects of all components were investigated using RT-PCR. Results: The SH-SY5Y cell viability increased in both groups exposed to 75 and 150 ppm barberry extract compared with that in the H₂O₂-treated group. The data showed that exposing SH-SY5Y cells to 30 ppm berberine significantly increased the cell viability compared with the H₂O₂-treated group; treatment with 150 and 300 ppm berberine and H₂O₂ significantly decreased the SH-SY5Y cell viability and was associated with berberine cytotoxicity. The mRNA levels of Bax decreased significantly under treatment with berberine at 30 ppm compared with the control group. A significant increase in Bcl-2 expression was observed only after treatment with the IC₅₀ of berberine. The expression level of Bcl-2 in cells exposed to both berberine and barberry extracts was also significantly higher than that in cells exposed to H₂O₂. Conclusion: The outcomes of this study suggest that treatment of SH-SY5Y cells with barberry extract and berberine could suppress apoptosis by regulating the actions of Bcl-2 family members.

Forest disturbance sometime considered as a tool of management as it believed that mid level disturbance constructs better micro-climatic conditions which ultimately boost up the plant diversity. The effect of different levels of disturbance on species composition and regeneration is very important. Present attempt was carried out in a temperate evergreen oak forest which was under various degree of disturbance. The study area is one of the large ranges of oak forest in Garhwal Himalaya and compensating various types of daily needs of local people. On the basis of IVI values Quercus leucotrichophora holds first position in all the disturbance zones whereas Myrica esculenta upgraded it's rank in highly disturbed zone and showed less impacted species by disturbance. Berberis aristata and Eupatorium adenophorum in shrub layer and Anaphalis adnata and Bidens pilosa in herb layer were found as disturbance friendly species because they attained higher rank in highly disturbed zone whereas Caryopteris foetida was found disturbance-sensitive in shrub layer. The banj oak regenerated well under mid disturbance as compared to no and high degree of disturbance and a sharp downfall in the species diversity was recorded with increasing magnitude of disturbance. Density-diameter curves showed a reverse trend of lower density in higher girth classes. The results of the study should be useful for the forest management strategies.
