The purpose of this research was to investigate cytotoxity of Sunbanhwalmyungeum extract. Cytotoxity was determined by MTT assay method. After tumor cell lines(G361, BI6F10, MDA, A549) transplantation, the extracts of SunBangHwalMyungEum and its composition oriental medicines were administered, cytotoxity was measured by absorbance. The results were obtained as follows. 1. Sunbanhwalmyungeum extract and its composition oriental medicines extracts showed the concentration was higher, the more cytotoxity increased. 2. Both water and ethanol extracts of Sunbanhwalmyungeum showed excellent cytotoxity against G361, B16F10, MDA, A549 and high cytotoxity over 80$\%$ against G361, B16F10, MDA except A549 at the concentration of 1000ppm. 3. In water extract, Rhei Radix et Rhizoma, Gleditsiae Spina, Trichosanthis Radix, Glycyrrhizae Radix, Ledebouriellae Radix showed excellent cytotoxity. In ethanol extract, Gleditsiae Spina, Citri Pericarpium, Trichosanthis Radix, Paeoniae Radix Rubra, Myrrha showed excellent cytotoxity. 4. Rhei Radix et Rhizoma, Gleditsiae Spina, Trichosanthis Radix, Paeoniae Radix Rubra showed high cytotoxity in both water and ethanol extrats. 5.

Basidiomycete, Agaricus blazei murill has grown Brazil naturally. It was first cultivated 1997 in Korea. Proteoglycan or polysaccharide which have the effect of immunopotency and anticancer were extracted from it. From the mycelium of cultivated mushroom, were extracted lectin, linoleic acid, FIII-2-b, and simmilar to glucomannan from fruit body of Basidiomycete Agaricus blazei. Fruit body was more studied than mycelium. The experiments were most in vivo study. The effect were shown on S-180, MethA tumor, Ehrlich ascites carcinoma, Shionogi carcinoma 42, Meth A fibrosarcoma by transferation of tumor cell line, specially effectiveness on the S-180. About immunopotenciation, were shown as activation of NK cell, pancreatic T-cell, helper T cell, enhancement of population of cytotoxity T cell. It was effect on the MethA tumor cells in vitro cell cytotoxity and has induction of apoptosis. Forthermore cytotoxity of many other tumor cell line, aneiognensis, cell cyle studies will be needed.

Three more unusual macrolides in addition to concnamycin B were isolated from the mycelium of Streptomyces sp. strain Bal6. These four compounds showed a potent cytotoxity to hunian cancer cell lines, SNU-1 (stomach cancer cell line), SNU-354 (liver cancer cell line), MCF- 7 (breast cancer cell line) and KB-3-1 (oral epidermoid carcinoma cell line). Interestingly, these compounds confered slight differential cytotoxity on RHEK-1, a human epidermal keratinocyte cell line immotalized by AD12-SV40 hybrid virus and RHEK-1/pSV$_{2}$ ras which was resulted from H-ras transfomation of RHEK-1. These compounds were determined to be concanamycin A, conca- namycin E and 0-methyl concanamycin B by NMR and other spectral analysis.

Moxibustion is one of major healing technique in oriental medicine. It has been widely used in many diseases such as rheumatoid arthritis, Hashimoto disease, breech presentation, etc. However, till now, effects of moxibustion on NK cell activity and relations between sympathetic nerve system(SNS) and the immune alteration induced by moxibustion were not well studied. This study was designed to evaluate effects of moxibustion on NK cell activity and the intervention of SNS in the alteration of NK cell activity induced by moxibustion. Splenic NK cytotoxity was measured in a standard 4-h 51Cr release assay. We measured the NK cytotoxity at after moxibustion stimulation for 1,3,5, and 7 days, and also measured the NK cell cytotoxity after 3 and 7 days burn stimulation with similar temperature. IL-2, IL-4, INF-γ in serum were measured by rat IL-2, IL-4, INF-γ ELISA TEST KIT. To evaluate the effects of sympathectomy on alteration of NK cell cytotoxity, 6-hydroxydopamine(6-OHDA : 5Omg/kg) was used. We showed that NK cell activity of moxibustion stimulation group increased at the 3rd day, and declined at 7th day in comparison with that of contol group. In moxibustion stimulation group, NK cell activity of 3 day stimulation group was significantly higher than sham group. On the contrary, in burn stimulation group, NK cell activity was significantly higher than that of sham groups at 3rd, 7th days. Patterns between moxibustion and burns were different. INF- γ level of 3 days moxibustion stimulation group significantly higher than sham group. IL 2 level among groups were not different. IL-4 was not detected in serum with this method. Sympathectomy abolished the NK cell activity alteration induced by moxibustion. The results suggest that moxibustion induces the alteration of NK cell activity, along with INF-γ and SNS is related to these effects.

The present study attempts to evaluate antioxidant activities of extracts from Abeliophyllum distichum. Nakai flower. The samples were collected in Jangyyeon-myeon, Goesan-gun, Korea and extracted with either hot-water or ethyl acetate (EtOAC). In DPPH, hydroxyl radical scavenging activity and $Fe^{2+}$ chelating activity of EtOAC extracts were 93.41%, 98.43%, and 7.38%, while those of hot-water extracts were 86.93%, 41.33% and 47.68% at 200 ${\mu}g/ml$, respectively. In ${\varphi}X$-174 RF I plasmid DNA cleavage assay, the protective effects of EtOAC and hot-water extracts against oxidative DNA damage were 82% and 17% at 200 ${\mu}g/ml$, respectively. Both extracts showed the protective effect of DNA migration by oxidative stress in intracellular DNA migration assay. Both extracts had no cytotoxity in NIH3T3 cells. Several polyphenolic compounds were identified such as 2-methoxy-benzoic acid, vanillic acid, phytol and pulegone by GC/MS. These results indicated that extracts of Abeliophyllum distichum Nakai flower showed antioxidant activities and protective activities against oxidative DNA damage and showed the possibility to be used as an effective natural antioxidants.

Objectives : The electroacupuncture was generally has been used in oriental medicine doctors. In recent years, there have been a few studies about safety and stability of acupuncture needle in itself, but then again research of acupuncture needle safety and stability on applying electroacupuncture have been insignificant. Therefore we investigated the safety and change in mechanical characteristic of acupuncture needle in electroacupuncture therapy. Methods : We observed mechanical characteristic change by SEM(Scanning Electron Microscope) and EDX(Energy Dispersive X-ray Spectroscopy), evaluated the hardness by vickers hardness tester. We used MTT assay and cell stain to study about biocompatibility of electroacupuncture. Results : In this study, any corrosion of material, alternation of elements, and change of hardness were not observed in surface analysis using SEM and EDX. In cytotoxity evaluation using MTT assay and cell stain, cell survival rate was low when practicing the electroacupuncture for more than 3 hours. Conclusions : Change of mechanical property was not observed based on the test results using surface analysis and hardness estimation by the electroacupuncture. And considering the biocompatibility, electroacupuncture was thought to be safe in an hour based on cytotoxity evaluation using MTT assay and cell stain.

The purpose of this study was to investigate the antimicrobial activity, antimutagenic and anticancer effects and dyeing properties of the fermented indigo extract. The methanol extract of fermented indigo showed a strong inhibition effect on Trich. mentagrophytes and antimutagenic activities against aflatoxin B$_1$(AFB$_1$) in the Ames test using Salmonella typhimurium TA 100. We also found in vitro anticancer effects of the methanol extract of fermented indigo and it was evaluated by using Clone M-3 mouse melanoma cells and A431 human epidermoid carcinoma cells and exerted little cytotoxity against 3T3-L1 embryo fibroblast cell. In the relationship between the K/S values of cotton and silk fabrics dyed with fermented indigo and dyeing repeating times, the K/S values became higher as the repeating times were increased. The K/S values were high when the fabrics were dyed at low temperture. The K/S values of cotton fabrics were higher than those of silk fabrics. Changes of surface color of silk fabrics were higher than those of cotton fabrics after water fastness test, laundering, irradiation and treatment of acidic and alkaline perspiration.
