  • We investigated the effects of two antimicrobial peptides (AMPs) isolated from Scolopendra subspinipes mutilans on neutrophil activity. Stimulation of mouse neutrophils with the two AMPs elicited chemotactic migration of the cells in a pertussis toxin-sensitive manner. The two AMPs also stimulated activation of ERK and Akt, which contribute to chemotactic migration of neutrophils. We found that AMP-stimulated neutrophil chemotaxis was blocked by a formyl peptide receptor (FPR) 1 antagonist (cyclosporin H); moreover the two AMPs stimulated the chemotactic migration of FPR1-expressing RBL-2H3 cells but not of vector-expressing RBL-2H3 cells. We also found that the two AMPs stimulate neutrophil migration in vivo, and that this effect is blocked in FPR1-deficient mice. Taken together, our results suggest that the two AMPs stimulate neutrophils, leading to chemotactic migration through FPR1, and the two AMPs will be useful for the study of FPR1 signaling and neutrophil activation.

  • Previously, we performed de novo RNA sequencing of Scolopendra subspinipes mutilans using high-throughput sequencing technology and identified several antimicrobial peptide candidates. Among them, a cationic antimicrobial peptide, scolopendrasin VII, was selected based on its physicochemical properties, such as length, charge, and isoelectric point. Here, we assessed the anticancer activities of scolopendrasin VII against U937 and Jurkat leukemia cell lines. The results showed that scolopendrasin VII decreased the viability of the leukemia cells in MTS assays. Furthermore, flow cytometric analysis and acridine orange/ethidium bromide staining revealed that scolopendrasin VII induced necrosis in the leukemia cells. Scolopendrasin VII-induced necrosis was mediated by specific interaction with phosphatidylserine, which is enriched in the membrane of cancer cells. Taken together, these data indicated that scolopendrasin VII induced necrotic cell death in leukemia cells, probably through interaction with phosphatidylserine. The results provide a useful anticancer peptide candidate and an efficient strategy for new anticancer peptide development.

  • The centipede is predatory arthropod that form head and numerous segments. It is known that there are about 3,000 species worldwide and 44 species (four species and seven families) in Korea. Among them, Scolopendra subspinipes called "Wang-ji-ne" has been known as an important medicinal resource and its value is expected to increase in the future. In this study, the Scolopendra subspinipes in Korea was classified as Chilopoda through morphological analysis of forcipule and venom gland, and a method for sex determination was established. These results are expected to be used as basic data for artificial breeding of Scolopendra subspinipes in the future, and through this, it is expected that it will greatly contribute to the expansion of the Scolopendra subspinipes market as medicinal resources.

  • This thesis discusses and analyzes Jeju island's shamanistic myth "Samgong Bonpoori" from the perspective of analytical psychology. Similar to the "I live on my fortune"-type folktales discovered in the Korean mainland, "Samgong Bonpoori" is such a widespread myth that similar folktales are found not only in East Asian regions, including Korea, Japan, and China, but also in Ireland. The essence of the story is as follows; One day, a father asked his three daughters whose fortune they lived on. The first two daughters claimed that they owe their lives to their parents. However, the youngest daughter, Gameunjang-agi, replied, against his expectation, that "I live on my own fortune," and showed her fortune and virtue were physically embodied in the line drawn from her genitals to navel. Her answer enrages his father so fiercely that she was expelled and forced to embark on a journey with no one but a black cow carrying food to accompany her. In retaliation for telling lies against her, Gameunjang-agi transformed her two sisters into a centipede and a mushroom, while her parents were turned into beggars afflicted with blindness. Afterward, Gameunjang-agi wandered around the country and eventually found love with a Chinese yam digger. Not long after, they got married, and as a couple, they stumbled upon roots of gold in fields, which brought them an incredible amount of wealth. After this miracle has happened, Gameunjang-agi began to wonder about the status of her parents and decided to organize a party for all the beggars and the blinds in the country. She eventually found her parents and got a chance to reconcile with her sisters. The story ends with her parents regaining their eyesight and Gameunjang-agi reestablishing herself as the "Goddess of Providence." "Samgong Bonpoori" is a myth about a God. A God is ontologically a supremely perfect being; however, in this thesis, it will be discussed as a part of a folktale. Gameunjang-agi can be seen as the anima archetype of the father, which reveals the process of a paternal consciousness being transformed over time. At first, her parents deny Gameunjang-agi. However, after years of suffering from blindness, they regain their eyesight and finally recognize their daughter. This signifies that Gameunjang-agi is a being that has come into the world for a certain "purpose." Gameunjang-agi embodies the creative function of "femininity" that can renew the existing collective consciousness embedded in the patriarchal system. Such recognition of femininity matters to men to a great degree as well as to women. Without knowing their true nature (femininity), the two sisters submit themselves to their parents and conventional values. Not until they suffer from being transformed and captured into small and insignificant beings, a centipede and a mushroom, which symbolize their shadow, they fail to develop their self-awareness. Meanwhile, by reconciling with her parents and sisters--playing a significant role in reuniting the family--Gameunjang-agi turns out to be a figure that can reveal what it truly means to have self-awareness and achieve Self-realization. In conclusion, this story illustrates that recognition of femininity matters to men to a great degree as well as to women, and women's Self-realization plays a critical role in revitalizing the collective consciousness embedded in the patriarchal system.

  • This study was performed to determine the whitening effect of organic solvent extracts from the centipede, Scolopendra subspinipes mutilans. We prepared different concentrations (50%, 70% and 100%) of ethanol, methanol, 100% ethyl acetate and water extracts. We tested melanin inhibitory effect and tyrosinase activity using B16/F10 melanoma cell. As a result, treatment of organic solvent extracts is decreased the biosynthesis of melanin and tyrosinase activity to 36 ~ 86%. Especially the 70% ethanol extracts was the most effective in B16/F10 melanoma cells. In the study on melanogenic protein expression, 70% ethanol extracts of Scolopendra subspinipes mutilans blocked glycosylation of tyrosinase. Therefore this result suggests that 70% ethanol extracts could be developed as skin whitening agents.

  • The Chinese red-headed centipede Scolopendra subspinipes mutilans, a member of the arthropod class Chilopoda, is a traditional medicine used for the treatment of several allergic diseases, such as atopy. S. subspinipes mutilans samples were collected from different regions of South Korea: Sancheong, Gyeongnam; Yeonggwang, Jeonnam and Jeju-do. The nutritional values of the centipedes were analyzed to extend the species' applications. The crude protein and fat contents of all samples were high and ranged from 54.9-55.8% and from 26.8-30.6%, respectively. Essential amino acids were present; lysine was the most common and accounted for 3.4-3.6% of the essential amino acids. Glutamic acid, which assists in improving concentration, memory and other cognitive abilities, was the most common non-essential amino acid at 6.8-7.1%. It had a similar content percentage in all three regions' samples. Additionally, unsaturated fatty acids were present, and oleic acid, which prevents cancer and cardiac disease, was the most common at 41.3-48.6% of each sample. Mercury, a hazardous substance, was detected at a range of 0.08-0.11 mg/kg in all samples; the amount was lower than the standard food allowance. Additionally, no pathogenic microorganisms, such as Escherichia coli and Salmonella spp., were detected. There were no significant differences between the nutritional factors of the S. subspinipes mutilans samples from the three regions. Based on the nutritional analysis, Chinese red-headed centipedes have the potential to be food and medicinal ingredients due to their proteins, essential amino acids, unsaturated fatty acids and nutritive capacities.

  • The purpose of this study was to examine the spatial and visual arrangement characteristics of Imsil Yi Ung-jae's old house's spatial and visual aspects in order to discover the value of landscape and traditional house garden. The results of this study are as follows. Dongchon-village in Dundeok-ri, where old house is located, is a typical form of with "Back to the mountain and facing the water(背山臨水)", and is located in the north of the three streams of water, forming a Jeonchaghugwan(前窄後寬). Dongchon Village, which has a traditional scenic spot between Danguidae(丹丘臺) and Samgyeseokmun(三溪石門), is understood to be the main street of Nojeokbong Peak and Gyegwanbong Peak, which is Ansan(案山), where the "A centipede flying in the sky(飛天蜈蚣形)". Yi Ung-jae's old house is the oldest existing high-priced house in the North Jeolla region and the closing price of a royal family of the Joseon Dynasty, which was arranged by Chunseongjeong(春城正), Yi Dam-son(李聃孫) in the mid-16C. The Japanese Invasion of Korea in 1592 and Japanese colonial era, the loyalty of the gate quarters, the filial piety of the gate quarters, and the faithfulness of the tablet(扁額) and Juryeons(柱聯) are enough to contribute to the rise of the value of a physical house. The men's quarters(Sarangchae), which are placed on a high-pocket or a layout without going against the sloping terrain, have the effect of making the distance as far as possible, enhancing its dignity and hierarchy as a royal building. In addition, the entrance to the main quarters(Anchae) through the four pillar gates(四柱門), the extensive support and the appropriation of the Chaewon(vegetable garden), and the official base for the Anchae are very unique compared to the general nobility. However, in the context of the postwar relationship, the shrine seeks to realize Confucian ideals while harmonizing with nature by arranging wide sponsorships around it. On the other hand, it is confirmed that there was a pond in the form of a circle in a square(方池圓島型) with a relatively large area, which is now disturbed and damaged. Written by the high priced planting species are sponsored pine trees, hackberry, persimmon trees, Japanese apricot flower, Ohmomiji, and plum tree in the side garden, as well as cotyledon trees in the outside garden. However, although flower bed(花階), which is built on the stone axis, is a place that clearly shows the expensive garden, it seems to have lost the texture of the plant due to the extremely high variety of species and the splendor that does not match the plant landscape of the flower world. Yi Ung-jae's old house is highly valuable as it is a portrait house of a prince of the blood in the mid-Joseon Dynasty. Based on these findings, this study proposed a plan to improve the management of high prices that could be met.
