  • The purpose of this study is to analyze the aesthetic characteristics of goth image which have had influence on literature, film, music and art, in modern fashion. The method of this study is to analyze the documentary about gothic and goth, and the fashion magazines since 2000. The results of this study are as follows: First, sensuality shows the excessive exposure of body and inner wear, and emphasizes a resistance of sexual consciousness and a image of independent, active, powerful woman. Second, androgyny shows the goth women wearing a men's cloth and encourages a person to have a perfect being and satisfaction. Third, horror shows the symbol of death and suggests a substance of desire hidden in our mind. Fourth, historicity shows victorian fashion which have a romance of gothic and baroque, not a cult but a modern image. In conclusion, goth image in modern fashion does not show a substance negative and horrorful, but a substance positive as a perfection, satisfaction, a sense of freedom, obliteration of a feeling of uneasiness and powerful woman's image.

  • A strain of Streptomyces sp. (YS-221-B) extracellularly produced an inhibitory substance for $\alpha$-D-Glucosidase. The substance was purified 96-fold from culture filtrate by dialysis, heat treatment, adsorption on active carbon, Bio-Gel P-10 and Sephadex G-75 column chromatography with yield of 9.2%. The substance was stable in pH range from 7.0 to 11.0 at 37$^{\circ}C$, and a treatment at 10$0^{\circ}C$ for 20 min diminished only 15% of the original activity. The inhibitor was not inactivated by the treatment of $\alpha$-, $\beta$-amylases, glucoamylases, trypsin and chymotrypsin but inactivated by pyoteases from Streptomyces griseus and Tritirachium album.

  • Isolation of the toxic substance which was produced by Streptentyces sp. and it's biorhemical characterestics and toxicity to fishes were reported in the previous paper. The present report includes antibiotic activity of the substance, inhibitory activity of the substance on the succinic dehydrogenase of fishes, and its effect on the blood corpuscles of a rabbit. An evident antibiotic activity of this substance was observed on Candida yeasts, but n$ot^1$on molds or bacteria. The substance inhibited the growth of Candida japonica and C. utilis to the 50% at the concentrations of 7.5 and 10.2ug per ml, respectively. The activity of succinic dehydrogenase obtained from various organs of Cyprinous carpio L. was also found to be inhibited by this substance. Original activities of the enzymes from tht brain, kidney, and liver, were inhibited by 75.4%, 38.2%, and 26.2%, respectively, but not the enzymes from the heart and spleen. Neither leukopenia nor leukocytosis was detected after the intravenous administration of the substince to the rabbit at the level of 6 mg per 2 kg body weight.

  • Dorsal root ganglion(DRG) cells are primary sensory neurons which contain some biologically active neuropeptides which play a role as neurotransmitters or neuromodulators. This study was performed to observe normal distribution of calcitonin gene-related peptide (CGRP) and substance P (SP) immunoreactive cells and colocalization of CGRP and SP in a single DRG cell of the lumbar DRGs($L_1{\sim}L_6$) in the Wistar Kyoto(WKY) rat by immunohistochemistry. About 55.8% of DRG cells contained CGRP-immunoreactivity, while about 12.7% of DRG cells showed SP-immunoreactivity. There was no significant difference in percentage of each neuropeptied-immunoreactive cells between each neuropeptide-immunoreactive cells between each levels of DRGs ($L_1{\sim}L_6$) (p>0.01). In size distribution, CGRP-immunoreactive cells were identified below $1,500{\mu}m^2$; SP-immunoreactive cells below $600{\mu}m^2$. In serial sections, about 86.7% of the SP immunoreactive cells contained CGRP immunoreactivity.

  • Antimetabolite N-2292 substance, an antagonist of L-aspartic acid and L-glutamic acid was isolated from the fermentation broth of Streptomyces. Taxonomical study on the producing strain made it a related species of Streptomyces albulus judged by cultural characteristics and carbon utilization. N-2292 substance was isolated as amorphous white powder with melting point at 185$^{\circ}C$. From the physicochemical characteristics of the substance, it was peptide like substance. It was active against Gram positive and Gram negative bacteria but negative against yeast and mold in its biological properties. It was reversed by L-Asp and L-Glu on the synthetic medium.

  • To develop environment-friendly agricultural products with anti-microbial activity against Sclerotinia sclerotiorum as a pathogen of sclerotium disease, Aristolochia tagala Champ. was extracted by methanol and its extract was fractionated into several solvent fractions. The chloroform fraction, which showed the highest antimicrobial activity, was separated by column chromatography and obtained forty three subfractions. The forty three fractions were searched the anti-fungal activities by bioassay. The most active No. 26 subfraction was analyzed by GC-MS. Each mass spectra, corresponding to each peak of chromatogram, was compared to MS database of Wiley library. As a result, 2,4-di-tetra-butyl-phenol, 2-mono-palmitin, 1-mono-stearin were profiled as maine compounds in No. 26 subfraction. Bioassay using commercial 1-mono-stearin to test for the anti-microbial activity conformed the antimicrobial active compound. In conclusion, 1-mono-stearin identified from Aristolochia tagala Champ. was antimicrobial chemical against Sclerotinia sclerotiorum.

  • The ethyl acetate (EtOAc) extracts from needles of Pinus densiflora were showed antimicrobial activities against bacteria, yeast and fungi. The antimicrobial active substance of EtOAc extracts were successively purified with solvent fractionation, silica gel adsorption column chromatography and Sephadex LH-20 column chromatography. The purified active substance was isolated as crystals and identified as benzoic acid by $MS,\;^{1}H-NMR\;and\;^{13}C-NMR$. The amount of benzoic acid was 0.608 mg per gram of fresh needle of Pinus densiflora.
