This study was performed to investigate the antimicrobial effect of Sophora angustifolia extracts against food-borne pathogens. First, Sophora angustifolia was extracted with methanol at room temperature, and the methanol extracts from Sophora angustifolia were fractionated using petroleum ether, chloroform, ethyl acetate, and methanol. The antimicrobial activity of the Sophora angustifolia extracts was determined using the paper disc method against food-borne pathogens and food spoilage bacteria. The methanol extracts of Sophora angustifolia showed the highest antimicrobial activity against Staphylococcus aureus and Salmonella typhimurium. A synergistic effect was found in the combined extracts of Sophora angustifolia and Portulaca oleracea, compared to the activity of each extract alone. Finally, the growth inhibition curve was determined using the methanol extracts of Sophora angustifolia against Staphylococcus aureus and Salmonella typhimurium. The methanol extract of Sophora angustifolia showed strong antimicrobial activity against Staphylococcus aureus at a concentration of 5,000 ppm. The 5,000 ppm methanol extract from Sophora angustifolia retarded the growth of S. aureus for more than 24 hours and of Salmonella typhimurium for up to 12 hours.

This research was performed to investigate protective effect of Sophora Subprostrata fractions against focal ischemic brain damage after middle cerebral artery(MCA) occlusion. Rats were divided into six groups: MCA-occluded group(Control); each administered groups with Sophora Subprostrata total phase(Total), Sophora Subprostrata Aqueous phase (Aqueous), Sophora Subprostrata BuOH phase(BuOH), and Sophora Subprostrata Alkaloid phase(Alkaloid) after MCA-occlusion; sham-operated group(Sham). The right MCA was occluded by A poly-L-lysine coated 4-0 nylon suture thread through the internal carotid artery permanently. Sophora Subprostrata and fractions were administered orally(5mg/ml) for 7 days after MCA-occlusion. The behavior of ischemic rats were examined at 24 hours, 3, 5 and 7 days after MCA-occlusion from the views of 4 different aspects: posture & balance tests(4 subtests), reflex tests(6 subtests), muscle-tone tests(3 subtests), and foot-fault test. The results showed that 1) in muscle tone test, Sophora Subprostrata total phase only increased reduced muscle tone function from 3 to 7 days, 2) in reflex test, Sophora Subprostrata total and Aqueous phase increased fast recovery from 24 hours and 3 days, 3) in posture & balance test, Sophora Subprostrata total and Aqueous phase increased fast recovery from 24 hours, and Sophora Subprostrata BuOH and Alkaloid phase increased posture & balance function from 3 days, but 4) in motor function test, Sophora Subprostrata did not show effective recovery compared with control group. In conclusion, Sophora Subprostrata has protective effects against brain damage at the early stage of focal cerebral ischemia. Sophora Subprostrata total and Aqueous phase produced more pronounced protective effect against focal ischemic brain damage.

This paper surveys the mordanting and dyeing properties of Sophora japonica L. Appropriate extraction, dyeing and mordanting condition of Sophora japonica L. were determined, and the effect of mordanting method on dye uptake and color fastness of dyed fabric was investigated. The maximum absorbance of Sophora japonica L. solution was 367.6mn, rutin solution was 365.6mn. The color of Sophora japonica L. solution was affected at pH 2 and pH 8~9. The optimum temperature to extract Sophora japonica L. was during 1 hour in 8$0^{\circ}C$. The effective dyeing temperature and time of silk were 10$0^{\circ}C$, 60min. K/S value of dyeing fabrics was increased by pre-mordanting treatment, especially Fe, Sn, Cr. In the case of Sophora japonica L. light fastness was increased by Fe mordanting. Perspiration fastness was better in acidic solution than that in alkaline solution. Fastness to rubbing and dry-cleaning were good in general.

In the course of screening natural extracts for hair growth, we found that the extract of dried root of Sophora flavescens has the prominent hair growth promoting effect. After topical application of Sophora flavescens extract to the back of C57BL/6 mice, the earlier conversion of telogen-to-anagen phase was induced. In addition, the Sophora flavescens extract revealed to possess potent inhibitory effect on $5{\alpha}$-reductase Ⅰ and Ⅱ activity. The growth of dermal papilla cells and mouse vibrissae hair follicle cultured in vitro, however, was not affected by Sophora flavescens extract treatment. RT-PCR analysis showed that Sophora flavescens extract induced mRNA levels of growth factors such as insulin-like growth factor-Ⅰ and keratinocyte growth factor in dermal papilla cells, suggesting hair growth promoting effect of Sophora flavescens extract is mediated through inhibition of $5{\alpha}$-reductase type Ⅱ activity and the regulation of growth factors in dermal papilla cells. Furthermore, Sophora flavescens extract also showed anti-bacterial effect on Propionibacterium acnes. These results suggest that Sophora flavescens can be used as a potent treatment agent for helping hair growth stimulation and acne inhibition.

Objectives : This research was performed to investigate protective effect of Sophora Subprostrata against transient global ischemic damage after 5-min two vessel occlusion. Methods : Gerbils were divided into three groups: Normal group, 5-min two vessel occlusion (2VO) group, Sophora Subprostrata administrated group after 2VO. The CCAs were occluded by microclip for 5min. Sophora Subprostrata was administrated orally(12mg/ml) for 7 days after 2VO. The histological and immunohistochemistrical analysis was performed at 72 hours and 7 days after the surgery each. For histological analysis, the brain tissue was stained with 1% cresyl violet solution and Immunohistochemistry for BAX and Bcl-2 was carried out to examine effect of Sophora Subprostrata on ischemic brain tissue. Results : The results showed that (1) Sophora Subprostrata has the protective effect against ischemia in CA1 area of the gerbil hippocampus 7 days after 5-minute occlusion, (2) the treatment of Sophora Subprostrata inhibits the expression of Bax relatively after 2VO-induced ischemia. That protective effect of the Sophora Subprostrata seems to be performed by regulating the proportion of Bax and Bcl-2 protein, (3) in hypoxia/reperfusion model using PC12 cell, the Sophora Subprostrata extract has the protective effect against ischemia in the dose of $2{\mu}/m{\ell}$ and $20{\mu}/m{\ell}$.This study suggests that Sophora Subprostrata has neuroprotective effect against neuronal damage following cerebral ischemia in vivo with a widely used experimental model of cerebral ischemia in Mongolian gerbils and that Sophora Subprostrata regulates the proportion of Bax and Bcl-2 protein following ischemia. And, Sophora Subprostrata extract has protective effects also on a hypoxia/reperfusion cell culture model using PC12 cell. Conclusions : Sophora Subprostrata has protective effects against ischemic brain damage at the early stage of ischemia.

With the aim of accumulating data that can be used to infer the basis for the acculturation of trees called 'Goe,' this study aims to identify the survival status of the pagoda and zelkova trees known as 'Goe' trees by comparing and analyzing the status of pagoda trees (Sophora japonica) and zelkova tree (Zelkova serrata) designated as a protected tree in Korea. The results of this study are as follows; Zelkova serrata designated as a protected tree grows the most, with 2,147 trees (29.4%) in Cheonnam, followed by Chungnam (16.5%) and Gyeongbuk (14.4%). However, Sophora japonica showed a different result from zelkova Serrata as the total number of 210 Sophora japonica (55.7%) in Gyeongbuk and Daegu is much larger than that of zelkova Serrata. As a result, in the Yeongnam region, where the Confucianism of Yeongnam was actively practiced, the existence of Sophora japonica is much larger than that of the Zelkova Serrata, which is not a coincidence, and it is difficult to determine it only based on their flora and planting distribution. Results of comparing protected trees of Sophora japonica and Zelkova Serrata showed that the average age of Zelkova Serrata wass 289 years, while that of Sophora japonica was 302 years, and that the average height of Zelkova Serrata wass 18 m, which is higher than the height of 16 m of Sophora japonica. The average diameter at breast height of Zelkova Serrata was 398 cm and that of Sophora japonica was 314 cm, which indicates that Zelkova Serrata is relatively big. Therefore, it can be assumed that Zelkova Serrata has a larger growth potential than Sophora japonica, and the possibility of growth as a big tree is also high, but it seems that the explanation that "they are relatively long-lived" is not clearly determined.

Objective : The objective of this study is to investigate the inhibitor effects of an traditional oriental herb, Sophora flavescens on the hepatic and renal side effects of chemotherapy by using B16-BL6 melanoma-injected C57BL6 mouse tumor model. Methods : In this study, the effects of an traditional oriental herb, Sophora flavescens, on the side effects of chemotherapy were studied using B16 melanoma-injected C57BL6 mouse tumor model. Results : Sophora flavescen has significant effect on the reduction of the side effects of chemotherapy. Sophora flavescen recovered the reduction of WBC and RBC during cisplatin chemotherapy. Water extract of Sophora flavescens significantly inhibited cisplatin-induced increase of serum blood urea nitrogen (BUN) which is a good indicator of renal toxicity. Sophora flavescens extract does not decrease the anti-tumor activity of cisplatin showing that it can selectively inhibit side effects of anticancer drugs preserving beneficial effort. Conclusion : Theses results suggest a possibility that Sophora flavescens extract can be used for cancer patients for the reduction of the side effects and improving the quality of life during chemotherapy of cancer patients.

The aim of study was to elucidate the antibiosis of the Sophora Radix extracts by ethanol solvent on bacterias. The antibiosis on bacterias was examined in moisture water included the Sophora Radix extract. The results are as follows; Minimum inhibitory concentration (MIC) of Sopora Radix extracts showed markedly lower on gram positive bacterias($0.0125{\sim}0.025$) such as aureus, B. subtilis, S. epidermids than that on gram negative bacterias such as E. coli, P. aeruginosa(>10). The MIC of moisture water included the Sophora Radiix which extracted by ethanol solvent was very low which meaned good antibiosis($0.0063{\sim}0.5$). The antibiosis of moisture water included the Sophora Radiix was improved by adding the ethanol on some baterias. In conclusion, Sophora Radix had excellent antibacterial effect. Therefore, it is expected that Sophora Radix can be practically used as the natural material of functional cosmetics for preventing the Bacterial inhibitory in skin.
