In the [Samguk sagi], is the origin story of , a Pansori novel from the late Joseon period. is derived from an Indian folktale. This article examines the narrative changes from the Indian folktale. Through this, I attempt to examine how the short fable developed into a fascinating story with numerous variants like . The five kinds of stories that I have observed all indicate the development of a common narrative. They also have a common character: terrestrial animals, deputy, and aquatic animals. However, in the original story, the more the character is brought up, the greater the persuasiveness of the action. In addition, the scale of the conflict expands due to the reorganization of the incident. Moreover, the theme of the narrative has diversified by utilizing the space as a contrast. Discussions reveal that a single story or storyteller does not create a fascinating story. The implication being that several narratives and numerous people together make the narrative changes.

This study aims to identify the family and lineage of a part of a "Fish Tribe Conference" in the section Tokkijeon by utilizing computer literature analysis techniques. First of all, we encode the classification for a pairwise comparison's type of each paragraph to build a corpus, and based on this, we use the Hamming distance to calculate the distance matrix between each classification for a pairwise comparison's. We visualized classification for a pairwise comparison's clustering pattern by applying multidimensional scale method, and hierarchical clustering to explore the characteristics of the 'fish family' line and lineage compared to the existing cluster analysis study on entire paragraphs of "Tokkijeon". As a result, unlike the cluster analysis of the entire paragraph of "Tokkijeon", which consists of six categories, the "Fish Tribe Conference" section has five categories and some classification for a pairwise comparison's accesses. The results of this study are that the relative distance between Yibon was measured and systematic classification was performed in an objective and empirical way by calculation, and the characteristics of the line of the fish family were revealed compared to the analysis of the entire rabbit exhibition.

According to the Established Regulations of National Institute of Safety Research, the skin-irritation test of BST-SR (Lucky Ltd.) was perfonned for seven days in New Zealand White Rabbits. During treatment periods no significant clinical symptom was observed. Significant changes such as erythema, scar tissue and edema were not shown on the applicating sites. According to Primary Irritation Index of Draize, skin irritation rate was assessed as "Zero". The eye irritation of BST-SR (Lucky Ltd.) was examined in nine New Zealand White rabbits, based on the Established Regulation of National Institute of Safety Research. 0.1 ml of test material was dropped on right eye, and after 20~30 seconds, three rabbits' eyes were cleaned with wann saline for 1 minute. Other six rabbits' eyes were left uncleaned. The untreated left eyes were negative control. The lesions of cornea, iris and conjuntiva were assessed by the Grade table (from the Regulation of National Institute of Safety Research), and it is concluded that BST-SR has no eye-irritation.

목적 : 본 연구는 배기음(排氣飮)이 토끼의 위장관내에서 화학물질에 의해 유발된 장관의 궤양에 유효한 효과를 발휘할 수 있는지를 검증하기 위한 실험이다. 방법 : 토끼 5마리를 한 군으로 하여 정상군과 체중 1kg당 200mg 분량의 mepirizole을 경구 투여한 군과 100mg/kg의 배기음(排氣飮)(경구투여)과 800Units/kg 분량의 catalase(정맥주사)를 mepirizole을 경구투여하기 2시간 전에 각각 전처치한 군으로 나누었다. Mepirizole을 경구 투여한 후 각각 24hr와 48hr에 토끼를 희생시켜 위장, 십이지장부의 궤양성 병변을 관찰하였다. 결과 : Mepirizole을 경구투여하여 위장 및 십이지장 기부의 궤양성 병변이 유발되었다. 배기음(排氣飮)(경구투여)과 catalase(정맥주사)를 전처치하였을 경우 궤양의 크기가 현저하게 줄어들었다. Mepirizole은 십이지장 점막에서 지질의 과산화를 증가시키는데 이는 수산화기와 관련되어 있음을 시사한다. 배기음(排氣飮)과 catalase를 전처치함으로써 mepirizole에 의해 유발된 지질의 과산화가 현저하게 억제되었다. 형태학상의 연구에서도 mepirizole의 처치에 의한 십이지장의 손상과 배기음(排氣飮)에 의한 방지효과가 나타났다. 결론 : 이러한 결과들로 볼 때 반응성산소기는 mepirizole에 의해 유발된 위장관 궤양의 병리변화 형성에 주요한 영향을 미치며 배기음(排氣飮)이 항산화작용을 통해 궤양의 형성을 억제하는 역할을 하고 있음을 나타낸다. 따라서 본 연구는 배기음(排氣飮)이 반응성산소기에 의해 매개된 인체 위장관질환에 치료적 역할을 할 수 있음을 제시하고 있다.

독성약물에 의한 급성신부전시 세뇨관세포의 물질 재흡수 장애에 대한 단삼(丹參) 추출액의 효과를 조사하였다. 토끼에 수은(HgCl2)을 10 mg/kg되게 피하 주사하여 급성신부전을 유발하였고, 단삼(丹參) 추출액의 효과는 수은을 주사하기 전 7일 동안 0.05% 액(液) 0.3 g/kg 용량을 경구 투여하여 관찰하였다. 수은을 주사하기 전 24시간 동안 요와 혈액을 채취하여 신장기능을 측정하여 대조기간(basal period)의 값으로 하였고, 수은을 주사한 후 24시간 동안 요와 혈액을 얻어 수은에 의한 신장기능 변화를 평가하였다. 수은을 처리한 후 사구체여과율이 대조값에 비해 감소하였고, 혈청내 creatinine 농도가 증가하였다. 이러한 결과들은 수은이 급성신부전을 유발하였음을 가리킨다. 수은을 처리한 동물에서 포도당 및 인산의 배설분율이 증가하였고, 이러한 변화는 brush-border membrane에서 물질의 이동장애와 Na-pump 활성의 감소에 기인하였다. 수은을 주사한 동물의 신장피질 절편에서 유기이온인 PAH와 TEA 이동이 억제되었다. 토끼의 신장조직에서 지질의 과산화가 수은을 주사한 후 증가하였다. 단삼(丹參) 추출액을 전 처리한 후 수은을 주사한 경우 수은에 의해 유발된 사구체여과율의 감소와 혈청내 creatinine 농도 증가 현상이 유의하게 완화되었다. 수은에 의한 세뇨관에서 물질의 재흡수 장애가 단삼(丹參) 추출액의 전처리에 의해 방지되었다. 단삼(丹參) 추출액은 수은에 의한 지질의 과산화를 억제하였다. 수은에 의한 급성신부전은 항산화제로 잘 알려진 DPPD에 의해 방지되었다. 이상의 결과를 종합하면 생체실험결과 수은에 의한 급성신부전의 유발과정에 지질의 과산화가 중요한 역할을 할 가능성을 보이고 있고, 단삼(丹參) 추출액은 수은에 의한 급성신부전을 방지하는 효과를 가지고 있으며, 그 효과는 단삼(丹參)의 항산화작용에 기인(起因)할 가능성이 많다.

Electromagnetic waves may induce various effects on nervous tissues either by thermal or non-thermal mechanisms. This paper intoduces a method to evalute the non-thermal effect to central nervous system by measuring the EEGs of the rabbits treated by nimodipine before exposed to weak microwave field. 20 rabbits were divided into 2 groups and their EEGs were measured after their head section were exposed to 2,450 MHz microwave with the power density of 10 dBm and 20 dBm respectively for 10 minutes and compared with those of the 3rd group of 10 rabbits which were not exposed. The 4th group of 10 rabbits were intravenously given with nimodipine before exposed to 20 dBm field to determine whether this drug would reverse the EEGs changes induced by weak microwave irradiation. As field poser exceeded 20 dBm although no significant physiological changes were observed, total induced EEGs power was remarkably decreased suggesting the presence of CNS activation. Using Fourier analysis on the EEGs signal it was found that remarkable decrease in delta band and increase in the alpha and beta bands in a significant manner(P<0.05) compared to control group. The changes were, however, not reversed by nimodipine-treatment. The effects may be pure thermal in nature because no significant change has been observed in nimodipine treated rabbits.

In this paper, SAR distribution is calculated according to the rabbit's head using approximation of its medium three layers model. Our experiment was classified 5 groups dependent on the power intensity of 2,450MHz microwave to measure EEG(Electroencephalograph) of rabbit, which was checked in left frontal lobe before and after irradiation of microwave. In results, mean total power of EEG was slightly decreased and mean composition percentages of $\theta$, $\delta$ and $\beta$ wave were increased after irradiation in observation. It means to decrease of elect- rophysiologic activity and trend of fast wave in brain after irradiation of its microwave. We analyzed the electrophysiological effect of the biobody quantitatively using measured EEG and estimated MPE (Maximum Permissible Exposure).

To investigate the effects of bacterial endotoxin on lipids and cytokines, and to explain the relationships between their changes, we carried out this study using experi-mentally Escherichia coli (E. coli) endotoxin-induced septicemic rabbits. The triglyceride and cholesterol concentrations in endotoxin groups were generally high (p<0.01 or 0.05) at all sampling time points (from 3hr to 24 hr), while phospholipid concentrations in endotoxin groups elevated in dose-dependent fashion at 3hr and 6hr after endotoxin injection compared to control group (p<0.05), There were significant negative correlations between lipids changes and cytokines (TNF-$\alpha$ and IL-1$\beta$) each other (p<0.05), and endotoxic rabbits having higher triglyceride of cholesterol levels shown relatively better conditions compared with others. As a result, the alterations in the lipid compositions caused by endotoxin may imply an active exhibition of the host defense mechanism rather than the disturbances of lipid metabolism.
