  • This study was to determine whether iontophoresis application of centipede venom would produce analgesic effect for clinical practice. Sixty patients suffered from musculoskeletal diseases who lived in Taejon city were analyzed by double-blind central study. After pre treatment, post treatment, post 20 minutes, post 40 minutes iontophoresis using centipede venom, we assessed the response to pin-prick sensation with Endomed 582 in myalgia patients. The results were as follows, control group showed pain threshold of 1.76, 2.03, 2.01, 2.02mA after treatment, but the pain threshold of 1.76, 2.21, 3.85, 3.87mA after iontophoresis application in study group. The pain threshold of Notermans pain score after 20-minute and 40-minute centipede venom iontophoresis group using centipede venom was higher than that after non-centipede venom iontophoresis group. The results showed that by the increasing the analgesic effect in the centipede venom iontophoresis group, especially in time of post 20 minutes after iontophoresis treatment. So we considered that the iontophoresis using centipede venom could be reduced pain of myalgia in musuloskeletal disease patients.

  • Scolpendra subspinipes (centipede) is pungent in flavor, activates the channels to stop pain, and, removes toxins and resolves masses. So it has been used as a folk remedy. We researched folk remedies which used centipede as a single medicine and results of its prior clinical and experimental study, and figured out that centipedes are effective on ulcerative disease, herpes zoster, clavus, insect bite, inflammatory disease, furunculus, pain disease by external therapy, and oral administration is effective on anti-cancer such as hepatoma and uterine cancer, cerebrovascular disease, inhibition of atherosclerosis, sedation of central nervous system, antipyretic action, and anti-inflammation, and centipede Herb-Acupuncture is effective on inflammatory disease and pain disease. Centipede preparation materials for external therapy were sesame oil, perilla oil, vinegar, salt, and, burnt alum. Fumigation of centipede treated paronychia, pertussis, and hemorrhoids. For the external therapy, the way of centipede powder mixing with other materials has been used. It is needed that we use dusted powder to make skin absorb its ingredients more easily, and we study intensely minor ingredients to make centipede components absorbed more effectively and do pharmacological action. Also, fumigation, a kind of another external therapy, is considered to be effective treatment of upper respiratory infection like pertussis, so it needs an in-depth study on centipede fumigation.

  • Mobility is one of the most important issues for search and rescue robots. To increase mobility for small size robot we have focused on the mechanism and algorithm inspired from centipede. In spite of small size, using many legs and flexible long body, centipede can overcome high obstacles and move in rough terrains stably. This research focused on those points and imitated their legs and body that are good for obstacle negotiation. Based on similarity of a centipede's legs and tracks, serially connected tracks are used for climbing obstacles higher than the robot's height. And a centipede perceives environments using antennae on its head instead of eyes. Inspired from that, 3 IR sensors are attached on the front, top and bottom of the first module to imitate the antenna. Using the information gotten from the sensors, the robot decides next behavior automatically. In experiments, the robot can climb up to 45 cm height vertical wall and it is 600 % of the robot's height and 58 % of the robot's length.

  • An antimicrobial molecule was purified from centipede, Scolopendra subspinipes mutilans L. Koch, by reverse phase-HPLC. Its molecular weight was determined to be 1208.5493 by using matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. Total amino acid composition analysis revealed that it consists of E, G, P, V, L, F, and W. It exhibited a broad antimicrobial spectrum against not only Gram-negative, but also Gram-positive bacteria. Furthermore, it was found to have an antimicrobial activity against vancomycin resistant enterococci (VRE). It may be a useful molecule for a new antibiotic development, especially against drug-resistant bacteria. We suggest that it may playa role in the defense system of this animal. This is the first report of a peptidic antimicrobial substance from centipede.

  • In a previous report, we identified several candidate antimicrobial peptides through de novo RNA sequencing of the centipede Scolopendra subspinipes mutilans. Here, we identify and characterize one of these peptides, Scolopendrasin I. We identified the centipede antimicrobial peptide Cecropin from the centipede transcriptome using an SVM algorithm, and subsequently analyzed the amino acid sequence for predicted secondary structure using a GOR algorithm. We identified an alpha helical region of Cecropin and named it Scolopendrasin I. We then assessed antimicrobial and hemolytic activity of Scolopendrasin I. Scolopendrasin I showed antimicrobial activity against various microbes, including antibiotic-resistant Gram-negative bacteria, in a radial diffusion assay. Scolopendrasin I had potent antibacterial activity against acne-associated microbes in a colony count assay and showed no hemolytic activity in a hemolysis assay. In addition, we confirmed that Scolopendrasin I bound to the surface of bacteria via a specific interaction with lipoteichoic acid and lipopolysaccharide, two components of bacterial cell membranes. In conclusion, the results presented here provide evidence that this is an efficient strategy for antimicrobial peptide candidate identification and that Scolopendrasin I has potential for successful antibiotic development.

  • The 8-hydroxyisocoumarin, named Centipedin, which has a significant antibiotic activity, was separated and solubilized with organic solvents, such as diethyl ether from centipede Scolopendra subspinipes multilans L. Koch. The Centipedin was purified by silicic acid column and high S cation exchange chromatography followed by reverse-phase HPLC. It was confirmed that Centipedin has a potent antibiotic effectiveness against Gram-negative Klebsiella pneumoniae ATCC 8308. The results showed that Centipedin blocks both DNA replication and RNA transcription during the growth of this pathogen in vivo. The biosynthesis of antibiotic 8-hydroxyisocoumarin was studied in vivo by feeding $[^{14}C]-labelled$ compound as a precursor to live centipede, in which $[^{14}C]acetate$ was the most efficiently incorporated into the Centipedin within 30 h after injection. Also, in vitro study on the biosynthesis of Centipedin showed that efficient incorporation of $[^{14}C]acetate$ occurred at pH range 5.0-7.0 for 10 h incubation and decreased significantly after then. It is suggested that 8-hydroxyisocoumarin is one of the defense compounds acting on bacterial infection in Scolopendra subspinipes.

  • In Korea, the centipede called "Wang-ji-ne" or "O-gong" is used as an important medicinal resource. This centipede has been known as Scolopendra subspinipes mutilans Koch 1878. Recent studies have assessed its taxonomic treatment in several geographical populations from China, Japan and Taiwan, but not Korea. We therefore attempted to assess exact species status for the Korean population of this subspecies using both morphological and DNA barcode methods. The result inferred from DNA barcoding showed that the Korean population is S. mutilans explicitly separated from S. subspinipes. Within S. mutilans, the Korean population is morphologically identical and genetically closer to the Chinese population rather than island populations of Japan and Taiwan. Particularly, the mainland populations from Korea and China share six haplotypes from 17 despite being far apart geographically.

  • 인터넷과 모바일 사용이 일상화되고 활용 범위가 넓어지면서 어디서나 온라인에 접속해 일을 처리하고 결정을 내리는 속도가 매우 빨라지고 있다. 기존 행동실험경제학 연구 분야에서 종속변인은 주로 점수나 상금 같은 수행 결과였으나, IT 발전과 함께 변화하는 시대적 흐름을 고려할 때, 의사결정의 '시간'도 온라인에서 중요한 결과변인으로 다룰 필요가 있다. 이 연구는 온라인의 전파성과 익명성에 주목해 돌발적 정서와 사회적 거리라는 심리적 변인이 온라인 지네 게임 속 의사결정 시간에 미치는 영향에 대해 알아보았다. 실험 결과, 게임수행시간은 분노조건에서 짧고, 행복조건에서 긴 경향이 있었다. 또 타인보다 지인과 게임을 할 때 게임수행시간이 더 길었다. 집중에 어려움을 느끼는 사람일수록 게임시간이 짧아졌고, 복잡한 문제를 싫어하는 사람일수록 자기 결정의 이유를 설명하는 데 시간을 짧게 쓰는 것으로 나타났다. 이 연구는 기존 연구에서 주목받지 못했던 의사결정시간을 결과 변인으로 다뤘다는 점에서, 그리고 온라인 의사결정 맥락에서 심리적 변인의 효과를 탐색했다는 점에서 의의가 있다. 후속 연구로 다른 온라인 의사결정 상황이나 심리적 변수들을 고려한 확장연구들이 가능할 것으로 기대된다.
