배경: 분자학적 표지자들과 식도암과의 관련성에 대해서 아직 뚜렷하게 밝혀진 바가 없다. 본 연구에서는 먼저 p53, Cyclin D1과 Ki67 지수 등 종양 표식자가 국내 식도암 환자에서 수술 후 얻어진 식도암 조직의 병기, 악성도, 임파선 전이 여부 등과 어떠한 관련성이 있는가를 알아보고 이를 이용해 향후 국내 식도암 환자에 대한 예후 분석 및 치료방침 결정 그리고 조기발견에 이용할 수 있는지 알아보았다. 또한 본 연구는 분자학적 표지자들의 임상적용의 기초를 마련하고자 하는 목적으로 시행하였다. 대상 및 방법: 1992년 3월부터 수술 후 조직절편이 보존된 124명의 환자를 대상으로 하였다. 조직절편의 파라핀을 제거한 뒤에 p53 변이, Cyclin D1의 과발현, Ki67 지수에 대한 면역조직화학 염색법을 시행하였으며 조직슬라이드상에서 세포분열지수를 구하였다. 이 결과와 임상적인 변수들과의 상관관계를 분석하였고, 환자의 생존 및 재발 결과와 비교하였다. 결과: 환자의 성별, 나이, 병기, 종양 크기, 타장기 전이 여부, 국소적인 재발 여부와 p53의 변이, Cyclin D1의 과발현, Ki67 지수, 세포분열 지수에 따른 통계적으로 유의한 차이는 없었다. Ki67 지수는 40 미만인 경우와 40 이상인 경우로 나누었을 경우 통계적으로 유의하게 생존기간에 있어서 차이가 나는 것으로 나타났으나(p=0.011) 다른 표지자들은 생존기간에 유의한 차이를 보이지 않았다. 결론: 높은 Ki67지수는 식도의 편평상피암의 예후에 나쁜 영향을 미치는 것으로 나타났으나 다른 표지자들은 영향을 미치지 않았다 이번의 연구를 통해 분자학적인 지표들이 임상적으로 가치 있는 인자가 될 수 있다고 판단되었다.

KiSS1-derived peptide receptor, a GPCR protein, binds with the hormone kiss peptin. They are important in the neuroendocrine regulation of reproduction and in the secretion of gonadotrophin-releasing hormone. Thus, analysing the structural features of the receptor becomes important. However, the three dimensional structure of the protein is unavailable. Hence in this study, we have performed the homology modelling of KiSS1-derived peptide receptor with 5 different templates. 30 models were constructed using two platforms - Easymodeller and ITasser. The optimal models were chosen based on the model validation. Two models were selected after validation. The developed models could provide useful for analysing the structural features of KiSS1-derived peptide receptor and their pathophysiological role in various disorders related to them.

Objective & Methods : The purpose of this study is to observe the effects of herbal-acupuncture with Lycii Fructus (LF-HA) at KI10 (Eumgok) on osteoporosis in ovariectomized (OVX) ddy mice. We carried out several experimental items which were known to be related with osteoporosis. Results : 1. Tibial BMD was significantly increased in the LF-HA group. 2. Tibial Ca level was significantly increased in the LF-HA group. 3. Osteoclast like cell in tibia was significantly decreased in the LF-HA group. 4. Histological change of tibia was improved, the trabecular bone thickness was significantly increased and the growth plate length was significantly decreased in the LF-HA group. Conclusion : These results suggest that LF-HA at KI10 has therapeutic effects on osteoporosis especially by way of suppressing osteoclast cells in ovariectomized ddy mice.

Peripheral neuropathy is a disease of multiple Peripheral nerves. Tingling, pins-and needles, numbness, burning and raw sensation are symptoms of peripheral neuropathy. These symptoms are frequently complained by patients who suffered from obstructive syndrome of Ki and blood (痺證). This case was reported to evaluate the effects of oriental medicine therapy on a patient with obstructive syndrome of Ki and blood (痺證). The subject was a female patient who had obstructive syndrome of Ki and blood (痺證). She complained of calf pain, cold sense, walking discomfort, insomnia, dyspepsia, anorexia etc. We administered the medicine with dispeling the cold pathogenic factor (寒邪), adjusting the constructive and defensive energy (調營衛), tonifying the Ki and blood (補氣血) by stage. After the treatment, the symptoms improved. This case suggests that oriental medicine therapy can be applicable to improve in symptoms with Peripheral neuropathy.

Conclusions for the relationship between a conceptional model of stress theory and its examination based on the Oriental medicine; 1. It was considered that a general conception of stress is included into the meaning of Ki in the Oriental medicine. 2. The response-based model to stress could be comparable to a conception of Ki-pathogens interchange In the Onental medicine. 3. The stimulus-based model may be explained as a modern conception of immoderation feeling related with an internal etiological factor, specially injury of seven emotions, among three groups of etiological factors for disease. 4. The feedback conception based on the interaction model could explain the principal of reversible emotion therapy in the nine Ki. 5. In the Oriental medicine, a study to clarify a emotional etiologic factor and its pathophysiologlcal mechanism has been continued for long time before establishment of stress theory.

Accumulation of pathogens in chest refers to a syndrome of fullness, stuffiness and pain in the chest, diaphragm, epigastrium and abdomen, which is ascribable to accumulation of pathogenic heat with stagnancy of fluid or phlegm in the chest. Retching refers to vomiting with sound but without any vomitus. It is usually ascribable to adverse flow of ki due to deficiency of stomach, or by pathogenic heat or cold, and failure in descending of the stomach-ki. It may also be found in Soyang disease. Bloody purulent stool refers to passing stool with blood and pus. It is formed mainly due to invasion of the stomach and the intestines by epidemic pathogenic summer-heat, steaming of stagnateed damp-heat fighting against ki and blood, or improper diet, obstruction of bu-ki stagnation of blood and ki.

Temporal and spatial distribution of Korean rice blast fungus (Pyricularia grisea) race KI-409 that has been rapidely increased since 1993 and became predominant in 1995 in Korea were investigated. Varietal resistance of current commercial cultivars of rice to the race was also tested in this study. The race KI-409 was first isolated from rice cv. Namyangbyeo in 1985. Since 1985 the race had been isolated mainly from the rice cultivars having BL1 BL7 pedigree as a resistance source. Distribution ratio of the race in 1995 was 23.7% in average and became a predominant in the P. grisea population in Korea. The race distributed widely and found in all the eight provinces in Korea. Many commercial cultivars such as Chucheongbyeo as well as those with BL1 or BL7 as a genetic background were found to be susceptible to the race KI-409.

Korean folk medicine 'Ki Rin Cho' has been used to cure stanching and counteracting poison. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of 'Ki Rin Cho', the morphological and anatomical characteristics of Sedum species growing in Korea, i.e. S. aizoon, S. kamtschaticum and S. latiovalifolium were studied. As a result, 'Ki Rin Cho' was proved to be Sedum kamtschaticum and Sedum aizoon.

The relationship between areal total phosphorus(TP) and areal hydraulic loading was identified and used as defining the trophic state of the reservoir. And three simple, conceptual TP models were tested against the measured in-reservoir TP concentration. The analyses were based on water quality data measured in the Ki Heung reservoir for two years. The results showed that Ki Heung reservoir has undergone eutrophic state, and Dillon's and Vollenweider's TP models were in close agreement with the measured annual mean TP concentration. However, the OECD's model understimated the measured annual mean TP concentration in the Ki Heung reservor. A discussion is given for the hypothetical application of TP loading plot which might be useful for establishing the TP control program in the resavoirs/lakes.
