Objectives : This study investigates the association between disease behind the Beijing Epidemic of 1232 and fever causing internal damages as mentioned in the Neiwaishang Bianhuolun. Methods : In order to narrow the fever causing diseases in the Neiwaishang Bianhuolun, the retrospective diagnostic method was used in analysis. Disease behind the 1232 Beijing Epidemic and the fever causing internal damages were categorized. Results : Fever causing diseases in the Neiwaishang Bianhuolun could be categorized as infectious disease, inflammatory disease, irritable bowel syndrome, and fever of unknown origin. The Beijing Epidemic was limited in scale with high fatality, of which possible diseases include infectious disease and inflammatory disease with epidemic medium. Fever from internal damage has a mild prognosis, is non-epidemic, and lacks accompanying symptoms such as acute stomachache, even when it happens with external damage. This narrows the possible diseases to IBS and fever of unknown origin. Conclusions : Among internal damage fever cases treated by Li Dongyuan, there were infectious diseases from the 1232 epidemic and inflammatory diseases with mild prognosis.

Objectives : This study aims to examine the multi-layered meanings of Li Dongyuan's concept of 'internal damage' through examining the origins of the 'internal damage' concept together with discussions derived from his 'Differentiation of Internal and External Damage'. Methods : Rather than Li's original works, those done by later doctors who were influenced by Li were thoroughly examined in this study to determine the relationships among internal and external damage, and external contraction. Results : Based on discussions related to the 'differentiation of internal and external damage' following Li, his concept of 'internal damage' could be understood as multi-layered, as it contains both spatial as well as pathogenic meaning. Therefore the meaning behind categorizations of internal and external damage, and internal damage and external contraction could be different. Li's 'internal damage' concept includes not only internal pathogen but elements of external contraction of wind and cold, which seems to have been integrated into the 'Cold Damage Theory' after Zhu Danxi, seemingly having changed the concept of cold damage. Therefore, discussions on the crossing between internal damage and external contraction have on one hand expanded the boundaries of each concept, while on the other hand, have caused confusion between the two at times. Conclusions : The concept of 'internal damage' has been widely accepted due to Li Dongyuan, on which related discussions have been centered. However, the concept was originally multi-layered, naturally leading to various discussions. Future studies should focus on the relationship of 'internal damage' with 'external damage' or 'external contraction', beyond the theories of Li.

The oriental medicine is not static knowledge. Since the publication of "Hwangjenaegyeong(黃帝內經)", it has unceasingly changed and developed, that changes and developments ate the reflex of culture and civil progression, and they also are active acceptance of the time's demand. when we look back into the history of the Oriental medicine, angle of understanding disease can be classified into two concepts ; internal-external and Eumyang. Internal-external is whether we find the source of disease internal or external. Eumyang is deciding which is more important between yin-essence and yang-gi which are components of the essence-gi of body. This thesis view course of development of theory of the oriental medicine since publication of "Hwangjenaegyeong(黃帝內經)" at certain point of internal-external and Eumyang and with those as background, will inquire into sameness and difference between the Korean medicine and the Chinese medicine, and provide an advanced course for the oriental medicine.

Pulse diagnosis that distinguishes internal injury from external injury by comparing the left and right of the chon pulse was formed in the process of Naegyoung's pulsation theory of ST9 and LU9 being assimilated into diagnostic method by taking chon pulse. The founder of school of internal injury, I Dong-won, expanded the horizon for this method to be widely used in clinical practice by especially explaining the specific application and theoretical background. According to him, pulse at ST9 which means chon pulse at the left hand, is bigger than the chon pulse at the right hand, it reflects external injury. Bigger "entrance pulse", a chon pulse at the right hand means internal injury. The reason is the left side of the body is a path for Yanggi so it controls the exterior part and the right side of the body is a path for Eumgi to descend so it controls the interior part. Internal injury develops as the spleen and stomach get injured. If the spleen and stomach is damaged essence derived from food cannot ascend to the stomach and will flow back to the lower part. As a result, fire of Eum type formed at the lower part will shoot up to the upper part and manifests external injury-like exterior syndromes. In this case, evidence distinguishing between internal and external injury is the fact that right hand pulse is bigger than the left hand. The important reason for distinguishing between internal and external injury is because when treating external injury caused by excess syndrome, pathogenic Gi should be dispelled. However, treating internal injury cased by deficiency syndrome, requires promoting the primordial Gi.

Objective : Malaria(瘧疾) is a disease that's main symptom is paroxysm - a cyclical occurrence of sudden coldness followed by rigor and then fever. Since the introduction of the cause and mechanism of malaria(瘧疾) in the "Suwen(素問)", including Cold malaria(寒瘧), Warm malaria(溫瘧), Heat malaria(癉瘧) and Wind malaria(風瘧), there has been over 20 different kinds of malaria, each of which are introduced in multiple medical texts. Method : Through comparison between "Suwen(素問)" and other medical texts, the categories, causes and mechanisms of malaria can be analysed and organized to overview the whole feature of it. Results & Conclusion : External pathogens of malaria(瘧疾) are wind(風), cold(寒), summerheat (暑), dampness(濕), miasmic toxin(瘴), pestilence(疫), ghost(鬼). Internal pathogens of malaria(瘧疾) are dietary irregularities(飮食不節), overexertion and fatigue(勞倦), phlegm(痰), seven emotion(七情). Malaria can be categorized into four groups according to the pathological mechanism that leads to paroxysm. They are latency of disease(伏氣), external contraction(外感), internal damage(內傷), and combination of disease(合病). Malaria-Paroxysm(瘧疾發作) occurs when the three following factors collide strongly : defense qi(衛氣), latent qi(伏邪) and external pathogen(新邪). When collision of the three factors takes place in the interior(裏), the body experiences chills. When it takes place in the exterior(表), the body experiences fever. The cyclical occurrence of Malaria-Paroxysm follows the circulation of defense qi.

Objective : I would like to determine the main factors, in other words, the subjects that are responsible for febrile paroxysm and how they interact at the time of onset, based on the "Discourse on Hak(瘧)" chapter of "Huangdi Neijing(黃帝內經)". Methods : First, the pathological mechanism of the paroxysm was examined as described in the text. Then the subjects in question were analyzed based on the contents of the text. Result : 1. Febrile paroxysm happens when the three factors coincide at the Fengfu(風府). The three elements are as follows: first defense qi(衛氣), second latent qi(伏邪) and third, external pathogen(新邪). 2. Fengfu(風府) is not a specific point, but a region which external pathogen(新邪) passes through during which the defense qi is deficient. Conclusion : Febrile paroxysm is not caused by either an internal pathogen or an external pathogen, but the interaction between the three elements of the internal and external pathogens and the condition of defense qi. Moreover, the site, Fengfu(風府), which the disease is manifested is not a specific point but a more general region where the pathogenic qi has invaded while defense qi has weakened.

Byeollyangchamsa has been a key factor in formation of Dongwon(東垣)'s theory on internal injuries. The majority regarded Byeollyangchamsa as just epidemic disease, while Dongwon(東垣) regarded it as internal injuries by improper diet and overstrain. However, an analysis of Dongwon(東垣)'s internal injury syndrome revealed that it was a kind of external affections caused by damp-heat. In particular, heat rather than dampness have developed as the disease got worse. Therefore It can be regarded as the serious syndrome to show the impairment of Gi(氣), blood, fluids and humors for pathogenic fire.

Objectives : Because of emphasizing a side of preventive medicine in the oriental medicine, an interest in Doinqigong(導引氣功: Physical and breathing exercise) has been elated recently. But, it has a limited sphere of application in the present south korea. Therefore we would like to bring out its sphere of application and detailed method in the oriental medicine classics. Method : We have researched theories and methods of Doinqigong in the Junghwaeujeon(中華醫典: Oriental medicine classic collections) DB according to below the procedure. (1) Making a related words list: We have used existing study of Doinqigong to make a list. It has been connected with Doinqigong. It includes not only technical terms, but also general terms. (2) Searching sentences: We have searched sentence that contain terms related with Doinqigong in the Junghwaeujeon DB. (3) Analysis of related sentences: We have searched and classified sentence by theory and method. Result : Results & Conclusion : (1) The total number of oriental medicine classics connected with Doinqigong is twelve. (2) The methods of Doinqigong have classified into three large groups: They are the Doinqigong for preservationing of good health, the Doinqigong for curing disease and the Doinqigong for internal organs and channels. (3) The number of Doinqigong for preservationing of good health in the seven oriental medicine classics is about ten. For example, the Okeumhi(五禽戱: Five animal's dance), the Paldangeum(八段錦: Eight motions of qigong) and so on. The number of oriental medicine classics connected with Doinqigong for curing disease is seven. They contain internal diseases, surgical diseases, diseases of five sensory organs and various diseases in the order of their frequency. The Doinqigong for internal organs and channels is only the Yookjageul(六字訣: Six sound's treatment).

It was described in "Somun Jogyeongron" that Eum(Yin)-Yang' deficiency, excess and exuberance. According to "Somun Jogyeongron", It was known that the syndrome of Yang deficiency and exuberance is belong to external contraction, Eum deficiency and exuberance is belong to internal damage. The syndrome of Yang deficiency is belong to Gyejitang[contraction of wind] which constitutional weakness as the main etiological factor of deficiency conditions. The syndrome of Yang exuberance is belong to Mahwangtang[cold damage] which constitutional strong as the main etiological factor of exuberance conditions. Eum deficiency is so dysfunction of the spleen and stomach that Eum fluid and essence is not engender, distributed. So the dysfunction of spleen and stomach makes dampness-heat obstruction and then makes Internal heat at last. The syndrome of Eum deficiency is applicable to bojungikgitang. As contrasted with Eum deficiency, Eum exuberance is occurred cold-dampness obstruction, which we call 'Eum exuberance'. The syndrome of Yang exuberance is applicable to Ijungtang. In the light of "Somun Jogyongron", We explain that the syndrome of Yin deficiency and Yin exuberance, which was caused by dampness-heat, cold-dampness obstruction and internal damage based on disorder of the spleen and stomach.

Objectives : The purpose and application method of the five kinds of Gagamjeong-gisan in the Onbyeongjobyeon were analyzed and their significance was examined. Methods : First, contents within medical texts on the Gwakhyangjeong-gisan, the original formula for the Gagamjeong-gisan were analyzed. Next, application, symptoms and pathogenic mechanism, treatment principle, composition of the Gagamjeong-gisan as written in the Onbyeongjobyeon were analyzed. Characteristics of each formula as deduced from this process were compared and examined. Results : The Gwakhyangjeong-gisan covers both external contraction and internal damage, applied regardless of external or internal symptoms. It restores the Yang qi of the Spleen and Stomach, balancing the Zheng qi to respond to the external qi. The Gagamjeong-gisan takes after the Gwakhyangjeong-gisan, reflecting such properties. However, the latter differs in that it excludes ingredients unfit for treating dampness-warmth, and uses different application methods according to the level of discharge of dampness pathogen. Conclusions : The Gagamjeong-gisan is modified from the Gwakhyangjeong-gisan, which is applied to cold damage and internal damage to better treat warm disease. It can be said to have acted as a bridge for warm disease scholars in composing formulas that deal with dampness-heat disease.
