Hundreds of medicinal herbs have been using for the purpose of diseases treatment and immune enhancement for human being and other animals including fishes. Among them, 49 species of medicinal herbs were selected and tested for antibacterial activities against 19 strains of fish pathogenic bacteria in different 4 species. The 49 medicinal herbs were extracted by water and ethyl alcohol. The extracts were freeze dried and some paper discs from the extracts were prepared for the evaluation of antibacterial activity. The tested pathogenic bacteria were 5 strains of Edwardsiella tarda, 5 strains of Vibrio sp., 4 strains of Lactococcus garvieae, 1 strain of Lactococcus raffinose, 1 strain of Streptococcus parauberius, and 3 strains of Streptococcus iniae. The Galla rhois (Obaeja), Gaeonnamu and Hwangleyon showed antibacterial activities on both gram negative and gram positive fish pathogenic bacteria. The Youkgae, Sangbaekpi, Bogolji and Gamcho showed very effective antibacterial activities on gram positive pathogens while Jiyu, Aeyoeb and Yeonkyo showed very effective on gram negative pathogens.

The cytotoxic and antibacterial activities of Sanguisorbae officinalis L., which is known as a major tannin source, were investigated to check the possible use of natural nutraceutics or cosmetics. The S. officinalis inhibited cancer cell growth in a dose-dependant manner. Also, the clear zone against various bacteria such as Staphylococcus aureus, S. epidermidis, E. coli were evident at 0.5 and 1 mg/disc. When the concentrations were 500 and 1,000 ppm, growth of all aerobic bacteria increased at early stage but decrease afterward. The results indicated that S. officinalis had the anti-skin cancer activity as well as antibacterial activity against skin-related bacteria.

Antioxidative effect of 42 medicinal plant extracts was screened to search natural antioxidants. The extracts of Terminalia chebula, Caesalpinia sappan, Sanguisorba officinalis, Rubus coreanus, and Alpinia katsumadai showed strong inhibition effect on DPPH radical, and LDL oxidation. Those of Eugenia caryophyllata, Alpinia officinarum, Zingiber officinale, Xanthium strumarium, Sophora japonica, Aristolochia contorta, and Alpinia katsumadai exhibited potent antioxidative activity on linoleic acid peroxidation. Among 42 medicinal plant materials, the extract of Terminalia chebula showed the highest scavenging activity $(3.08\;{\mu}g/ml)$ on DPPH radical which was higher than that $(13.52\;{\mu}g/ml)$ of ${\alpha}-tocopherol$. The extract of Terminalia chebula showed also stronger inhibition activity on LDL oxidation than that of ${\alpha}-tocopherol$ did.

This study aims to analyze the sources of restoring of Geungnakjeon(極樂殿) and creation of the buddhist mural paintings(後佛壁畵) of Muwisa(無爲寺) in Gangjin(康津). Muwisa Geungnakjeon was constructed in 1430(in the twelfth year of King Sejong's(世宗)reign). At that

Purpose: Borage oil (BO) and safflower oil (SO) are efficacious in reversing epidermal hyperproliferation, which is caused by the disruption of epidermal barrier. In this study, we compared the antiproliferative effect of dietary BO and SO. Altered metabolism of ceramide (Cer), the major lipid of epidermal barrier, was further determined by measurement of epidermal levels of individual Cer, glucosylceramide (GlcCer), and sphingomyelin (SM) species, and protein expression of Cer metabolizing enzymes. Methods: Epidermal hyperproliferation was induced in guinea pigs by a hydrogenated coconut diet (HCO) for 8 weeks. Subsequently, animals were fed diets of either BO (group HCO + BO) or SO (group HCO + SO) for 2 weeks. As controls, animals were fed BO (group BO) or HCO (group HCO) diets for 10 weeks. Results: Epidermal hyperproliferation was reversed in groups HCO + BO (67.6% of group HCO) and HCO + SO (84.5% of group HCO). Epidermal levels of Cer1/2, GlcCer-A/B, and ${\beta}$-glucocerebrosidase (GCase), an enzyme of GlcCer hydrolysis for Cer generation, were higher in group HCO + BO than in group HCO, and increased to levels similar to those of group BO. In addition, epidermal levels of SM1, serine palmitoyltransferase (SPT), and acidic sphingomyelinase (aSMase), enzymes of de novo Cer synthesis and SM hydrolysis for Cer generation, but not of Cer3-7, were higher in group HCO + BO than in group HCO. Despite an increase of SPT and aSMase in group HCO + SO to levels higher than in group HCO, epidermal levels of Cer1-7, GlcCer-A/B, and GCase were similar in these two groups. Notably, acidic ceramidase, an enzyme of Cer degradation, was highly expressed in group HCO + SO. Epidermal levels of GlcCer-C/D and SM-2/3 did not differ among groups. Conclusion: Dietary BO was more prominent for reversing epidermal hyperproliferation by enhancing Cer metabolism with increased levels of Cer1/2, GlcCer-A/B, and SM1 species, and of GCase proteins.

Aegiceradienol (28-noroleana-12, 17-dien-$3{\beta}$-ol) was isolated from the roasted Sanguisorbae radix and its structure was elucidated by various spectroscopic techniques. Aegiceradienol was an artifact produced by heat treatment of the herbal drug. Its content was increase as the time of heat treatment increased.

In this paper, an algorithm for suppressing acoustic noises contained in stethoscope sound is proposed and implemented in real-time using an embedded DSP system. Sound collected by stethoscope is down-sampled and band-pass filtered, and later an NLMS adaptive filter is used to cancel the acoustic noise induced from external noise sources. Also, the unpredictable impulsive noises due to fabric friction and instantaneous tapping are detected using the SD-ROM algorithm, and suppressed using an algorithm approximating the morphology filter. The proposed algorithm was tested using signals collected with a digital stethoscope mockup, and implemented on an ARM920T-based DSP system.

To detect anxiolytic activity from Sanguisorbae Radix we used various animal models of fear or anxiety that are sensitive to known anxiolytic drugs. While diazepam showed significant anxiolytic activities in all five animal models empolyed in this study, $5-HT_3$ antagonist ondansetron and ethylacetate fraction of Sanguisorbae Radix did show anti-anxiety effects in social interaction and two compartment exploration tests. Ethylacetate fraction of Sanguisorbae Radix and 5-HT related drugs like ondansetron and buspirone, however, seem to have merit over diazepam in terms of not causing drowsiness. Among ten subfractions obtained from ethylacetate fraction of Sanguisorbae Radix by silica gel chromatography, subfraction I showed higher anxiolytic activities than subfraction DEF in two animal models, social interaction and two compartment exploration tests. There is growing evidence for the role of 5-HT in the control of anxiety. We hope that new compound(s) will be found from the active fractions of Sanguisorbae Radix as a potential anxiolytic agent in the future.
