  • Dyeing fastness and antibiosis effects of fabrics dyed with wormwood, which has been used in folk medicines and dietary life in Korea for a long time, were studied through dyeing small overcoats, which are used as diapers, with wormwood extract. As for the dying fastness test results, the fastness of decoloration was not that good but the pollution level showed a relatively positive result. As for the antibiosis effect results, the antibiosis of the dyed sample was better than the original sample on 3 kinds of bacteria, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and on 2 kinds of the fungi(Eumycetes). Aspergillus niger and Candida albicans. Especially, the sample that was mordant with CaCl2 and FeSO4·7H2O showed the best antibiosis effect. On the other hand, the sample that showed the best antibiosis effect was the refined fabric, which is a fabric that is not dyed.

  • 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.

  • In order to elucidate roles of lactic acid bacteria(LAB) for the antibiosis occurring in th fermenting environment of Kimchi, 2.052 strains of LAB were isolated from Kimchi. Fifty tow strains which showed antagonistic effect against 4 indicator strains were finally selected and investigated. Based upon responses to protease treatment, antibiosis of the 52 strains of LAB were classified into 3 types. Type A antibiosis resulted from action of antibiotic-like substances which were not affected by protease treatment and which had broad action spectra against even natural inhabitants of Kimchi. Type B antibiosis was due to bacteriocin-like substances which were very sensitive to treatment of protease and more effective against foreign bacteria than original inhabitant microflora. Type C antibiosis was owing to proteinaceous compounds which were activated or induced by the presence of protease and then exerted antibacterial activities. Therefore, lactic acid bacteria appeared to contribute to antibiosis of Kimchi by the concerted action of these three different types of antibacterial compounds. As one of model system for type B bacteriocin, the antagonistic compound produced by LAB31-9 as well as th producer strain itself was further charaacterized. Strain LAB31-9 was identified as L. casei. Bacteriocin produced by LAB31-9 was proteinaceous and stable over wide range of pH and to various solvents, but very labile to heat treatment. Its mode of action was bactericidal. Based upon these data, bacteriocin produced by LAB31-9 was named as 'caseicin K319'. Genetic determinant for the bacteriocin production of LAB31-9 was located in the chromosome.

  • To separate anticaries and antiinflammation from Aloe vera peel, we investigated a inhibited effect of Streptococcus mutans JC-2 that was antibiosis, glucosyltransferase activity about aloe-emodin and barbaloin. Aloe-emodin and barbaloin had strong antibiosis activity against Streptococcus mutans JC-2, they were especially antibiosis effect to low growth and prolong lag phase at attachment concentration 100$\mu\textrm{g}$/mL. The reduction rate of a culture fluid became to lessen than the comparison group for aloe-emodin and barbaloin. The intracellular materials of Streptococcus mutans JC-2 were to leakage as much as attachment concentration addition of aloe-emodin and barbaloin but there was no significant difference membrane demage between two active substances. The activity of GTase was inhibited by aloe-emodin and barbaloin and their inhibition rate was respectively 99.8%, 98.4% at the attachment concentration 100$\mu\textrm{g}$/mL.

  • Having silk dyed with some pigment extracted from the skin of an onion, examined the change of color by time and frequency of dyeing and a mordanted cloth, and the antibiosis of a dyed cloth and a mordanted cloth. The result of this were as follows ; 1. The pigment of an onion was easily extracted in the hot water of $40^{\circ}C$ and much more extracted as the temperature of water rises($70^{\circ}C$). 2. As a result of dyeing it by the change of time, 30minutes, 60minutes, 90minutes and the frequency of dyeing, once, twice, three times after filtering the extracted solution, the one dyed three times for 30minutes was the best. 3. The difference of color of a mordanted cloth was the highest in the mordant of $SnCl_2\;2H_2O$ on the basis of the value of L of the non-mordant dyed three times. 4. The mordant of copper sulfate was proved to have the highest antibiosis in the antibiosis of a dyed cloth and a mordanted cloth, and it was proved that the pigment of the skin of an onion had excellent antibiosis.

  • This thesis tried applying Ayurvedic hair and scalp care program and analyzing its effect. Ayurvedic treatment strengthens our immunity through natural healing power. I measured with MIC test and Halo test in order to examine the antibacterial efficacy against colonies which reside in head, when Ayurvedic base oils and essential oils were used on hair and scalp. Finally, I reached the results as follows. I examined the antibacterial efficacy of base oils and essential oils against Bacillus subtilis and Propionibacterium acnes, based on the MIC test with 9 kinds of base oil and 18 kinds of essential oil. By way of experiment, base oils did not show the antibacterial efficacy from all colonies, and in case of essential oils, such as Chamomile, Clary sage, Jasmine, Neroli and Rose oil, the antibacterial efficacy against two colonies did not appear by the measure of below 5%. It turned out that Thyme, Geranium, Lavender and Tea tree had an high effect on two colonies. According to the Halo test which experimented on 7 kinds of bacteria with the essential oils like Geranium, Lavender and Thyme and with the base oils like Sesame and Coconut, it went to prove that base oils was inefficient on antibiosis. It was examined that all of essential oils had the effect on antibiosis from 7 kinds of bacteria. Thyme showed the best efficacy of antibiosis in the MIC and the Halo test.
