The purpose of this study is to understand the Chinese noodles(mian tiao). Wheat seems to have been cultivated 3-4,000 years before according to the archaeological evidences from the neolithic sites. The five grains(rice, millet, beans, barley, barnyard millet) already appeared in the period prior to Chin dynasty and were used as whole grain, but it was not until Chun Chu Zhan Guo period that the introduction of the flouring method stimulated the cultivation of wheat. In Chin-Han period, when water power and animal force were put into usage to facilitate the mass production of wheat flour, 'Bing', a designation for all the food made of wheat first appeared in the literature, and it was this 'Bing' that had later developed into noodles. In Wei Chin Nan Bei Chao period, roasted 'Bing', namely 'Kao-Bing' made its first appearance, and in Tang period, various noodles were created with the increase of restaurants specialized in noodles. In Song dynasty, 'La-Mian', the noodles stretched and beat from noodle dough, was first introduced, and in Yuan period, invention of drying method made the appearance of dried noodles, 'Gua-Mian', possible, which was good for easy and long preservation. Qing dynasty developed the noodles with a variety of assorted ingredients. The Chinese noodles are classified by various standards such as main ingredients, cooking methods, kinds of sauce, secondary ingredients, shape, eating method, flavor, and look.

Two scale worms of the family Polynoidae, Arctonoe vittata (Grube, 1855) and Hyperhalosydna striata (Kingberg, 1856) were found for the first time from Korea by SCUBA diving survey. The two species are free-living organisms or associated commensally with a wide variety of other invertebrates. Specimens of A. vittata were collected from the East Sea and were closely associated with asteroids, holothuroids, gastropods and nudibranchs species. Specimens of H. striata were collected from Jeju-do Island, and of these, one specimen was collected in a tube of eunicid species. The two species can be easily distinguished from their congeners by distinct morphological characteristics as follows: (1) A. vittata has pigmented band near segment eight and two kinds of neurochaetae; (2) H. striata has reddish-brown longitudinal striped elytra. The morphological key characteristics of both species agreed well with their original descriptions and redescriptions. In this study, the descriptions, detailed illustrations and ecological photographs of two species based on Korean materials were provided.

Microtubule-associated protein 1B (MAP1B), a member of MAP1 family, plays a key role in neuronal development. MAP1B binds to many kinds of proteins directly or indirectly. This study was performed to investigate whether MAP1B interacts with GAPDH in bovine follicles using immunoprecipitation (IP) with Western blot analysis and immunohistochemisty. The mRNA expressions of MAP1B and glyceraldehydes 3-phosphate dehydrogenase (GAPDH) were down-regulated in bovine follicular cystic follicles (FCF). In parallel with the mRNA levels, their protein levels were also down-regulated in FCFs. In addition, MAP1B and GAPDH were co-localized at the cytoplasm of follicles. IP with Western blot analysis showed that MAP1B bound to GAPDH in normal follicles, but their binding was absent in FCFs, suggesting a low level of MAP1B and/or GAPDH expressions in FCFs. Taken together, these results suggest that MAP1B interacted with GAPDH may play a role in bovine follicle development, and that GAPDH does not function always as a loading control in bovine follicles.

The purpose of this study is to analyze the aesthetic characteristics of traditional Korean patterns appearing on fashion collections from 1990 to 2005. Traditional Korean patterns have been used as an important element to express a Korean image since the 1990s. Frequently used patterns included several kinds of geometric patterns, plant patterns(flower, peony, Four Gracious Plants), and Chinese character patterns. Specifically, since the 2000s, animal patterns such as tiger, Chinese phoenix, and giraffe which were not often used, plant patterns such as arabesque, peony, and flower, and a variety of Chinese character patterns appeared. For the expression techniques, while embroidery and printing was often used in the 1990s, they became varied into printing, beading, embroidery, gold and silver leaf, and hand painting after 2000 as a result of designers' active attempts. The aesthetic characteristics of fashion design with its focus on traditional patterns were analyzed. First, Chinese character patterns and phoenix pattern which were mainly used for a court suit, and show the excellence and unique originality of Korean culture. Second, traditional Korean patterns directly and indirectly imply symbolistic significance of lucky sign and illustrate the use of various lucky sign patterns. Third, traditional Korean patterns such as arabesque or peony were expressed by colorful embroidery to add decorative beauty. Finally, traditional Korean patterns reflect a naturalistic worldview and are completed finished as the design.

The regional distribution and relative frequencies of endocrine cells were studied immunogistochemically (PAP methods) in the alimentary tract of the tree frog, Hyla areorea japonica, using specific antisera against serotonin, somatostatin, bovine Sp-1/chromogranin (BCG), cholecystokinin (CCK)-8, vasoactive intestinal polypeptide (VIP), gastrin, bombesin, secretin and pancreatic polypeptide (PP). Six kinds of endocrine cells were identified in this study, These immunoreactive cells were located in the gastric glands of stomach regions and in the basal portion of the epithelium of the intestinal tract or esophagus with variable frequencies. They were spherical or spindle-shaped. Serotonin-immunoreactive cells were observed in the whole alimentary tract including the esophagus. Somatostatin-immunoreactive cells were also detected throughout the alimentary tract except the rectum. CCK-8-immunoreactive cells were observed from the pylorus to ileum. Vip-immunoreactive cells were restricted to the rectum. Bombesin-immunoreactive cells were restricted to the fundic gastric regions and gastrin-immunoreactive cells were restricted to the pylorus. However, no BCG-, secretin and PP-immunoreactive cells were demonstrated in this study. In conclusion, the regional distribution and relative frequency of the endocrine cells in the alimentary tract of the tree frog were similar to other anuran species, but some differences which may be caused by feeding habits and species specification were also observed.

This study has demonstrated the molecular variation of 5S rRNA genes in 15 Allium subgenus Rhizirideum and 1 Allium subg. Allium. For cloning of the 5S rRNA genes, PCR products were obtained from amplification with oligonucleotide primers which were derived from the conserved coding region of 5S rRNA genes. These amplified PCR products were cloned and identified by FISH and sequence analysis. The 5S rRNA loci were primarily located on chromosomes 5 and/or 7 in diploid species and various chromosomes in alloploid species. The size of the coding region of 5S rRNA genes was 120 bp in all the species and the sequences were highly conserved within Allium species. The sizes of nontranscribed spacer (NTS) region were varied from 194 bp (A. dektiude-fustykisum, 2n=16) to 483 bp (A. sativum). Two kinds of NTS regions were observed in A. victorialis var. platyphyllum a diploid, A. wakegi an amphihaploid, A. sacculiferum, A. grayi, A. deltoide-fistulosum and A. wenescens all allotetraploids, while most diploid species showed only one NTS region. The species containing two components of NTS region were grouped with different diploid species in a phylogenetic tree analysis using the sequences of 5S rRNA genes and adjacent non-coding regions.

Tea flavonoids and polyphenols are well known for their extraordinary antioxidant activity which is considered important for anti-aging processes in animals. This study evaluated the anti-wrinkle effects of three different kinds of tea (Camellia sinensis) water extracts (CSWEs) including green, white, and black teas using a photoaged hairless mouse model. Data showed that the CSWE-treatment greatly improved skin conditions of mice suffering from UVB-induced photoaging, based on the parameters including the skin erythema index, moisture capacity, and transepidermal water loss. In addition, the wrinkle measurement and image analysis of skin replicas indicated that CSWEs remarkably inhibited wrinkle formation. In histological examination, the CSWE-treated mice exhibited diminished epidermal thickness and increased collagen and elastic fiber content, key signatures for skin restoration. Furthermore, the reduced expression of MMP-3, a collagen-degradative enzyme, was observed in the skin of CSWE-treated animals. Interestingly, comparative data between green, white, and black tea indicated that the anti-wrinkle activity of white tea and black tea is equally greater than that of green tea. Taken together, these data clearly demonstrated that CSWEs could be used as an effective anti-wrinkle agent in photoaged animal skin, implying their extended uses in therapeutics.

Two kinds of humoral factors were observed in 2 orders, 7 families, 10 genera, and 15 different species of Korean ascidians. They are the naturally occuring hemagglutinins and/or hemolysins against human erythrocytes A, B, and 0. All but two species showed aggregative activity, although there were considerable variations in titer. The weak agglutinating and lytic activities were increased in the presence of $Ca^{++}$. Much higher activities of agglutination and/or lysis were shown in the hemolymph than extracts from tissues, and a higher response was shown in adults than in juveniles. No distinct differences from collected locations were observed. The hemolymph of Ciona intestinalis showed a strong hemolytic (cytotoxic) and weak agglutinins capacities. In addition, hemolymph of Styela plicata and Styela clava clava also showed hemoagglutining and hemolytic activities. Botryllus tuberatus had hemagglutining and weak lytic activities. Other species showed only hemagglutining activity. These agglutining activities are probably responsible for carbohydrate recognition in solitary or colonial ascidian. The lytic activity is probably responsible for antibacterial defense and nonfusion reactions between allogeneic colonial ascidians, especially the genus of Botryllus. The occurrences of humoral factors in ascidians were independent of their geographic distributions.

This study was carried out to obtain the information concerning the perception and utilization patter of the housewives about the edible oil and fats. Data were obtained through questionnaires from 442 housewives in Chonbuk area. The eating frequency of food that used oil & fat was affected by age, residing area and educational level. family's preference score of food that used oil & fats was 3.34 point in the 5 point scale. 47% of the subjects answered that the intake rate of oil & fats had more from vegetable oils than animal sauces. Most of the subjects had negative response such as increased cholesterol and body weight for psychological state after the intake of food that used oil & fats. The main reason why some housewives did not use frequently oil & fats was inconvenience of tidying up. The kinds of the oil & fat used frequently were soybean oil, sesame oil, com oil and perilla oil. The nutrition knowledge score rotated to oil & fat was 7.62 point in the 10 point scale. The eating frequency of food that used oil & fats and its preference were positively correlated. These results indicate that the housewives haute a widespread tendency to pursue a health and convenience in the utilization of edible oil & fats.

To assess inhibition mechanisms of a Phellinus igniarius (PI) extract on cancer, C57BL/6 mice were orally treated with PI extractive after or before implanting H22 (hepatocellular carcinoma ) or B16 (melanoma) cells. Mice were orally gavaged with different doses of PI for 36 days 24h after introduction of H22 or B16 cells. Mice in another group were orally treated as above daily for 42 days and implanted with H22 cells on day 7. Then the T lymphocyte, antibody, cytokine, LAK, NK cell activity in spleen, tumor cell apoptosis status and tumor inhibition in related organs, as well as the expression of iNOS and PCNA in tumor tissue were examined. The PI extract could improve animal immunity as well as inhibit cancer cell growth and metastasis with a dose-response relationship. Notably, PI's regulation with the two kinds of tumor appeared to occur in different ways, since the antibody profile and tumor metastasis demonstrated variation between animals implanted with hepatocellular carcinoma and melanoma cells.
