This study searched the philosophical and medical thought of mutual understanding and human body. Mutual understanding is a fundamental problem in all branches of oriental studies. In other words, mutual understanding becomes the existential foundation of heaven-earth-human(三才). So human beings, heaven and the earth can't exist if there is no mutual understanding. It comes out the problem of self-consciousness in philosophy, and qi movement pattern like upward, downward, inward and outward movement in traditional korean medicine. Human beings have mutual understandings with heaven and the earth from a macroscopic standpoint, on the other side the human body from a microscopic standpoint. Qi movement is the mutual understanding and response of qi in human body, so with which the physiological functions and pathologic changes of viscera and bowels comes out. Therefore we want to present how to complete qi movement between viscera-bowels and organs to examine mutual understandings in human body closely. The results was summarized as follows; First, upbearing the clear yang and down bearing the turbid yin of spleen-stomach is main pivot of upward and downward of qi movement, and it is true form of mutual understandings between viscera and bowels, so upward, downward, inward and outward movement of whole viscera and bowels can be controlled by spleen-stomach. Second, by restraining relationships between downward heart fire and upward kidney water, heart fire and kidney water have close communications physiologically and pathologically as upper-lower, yin-yang and water-fire. Third, by restraining relationships between upbearing and effusion of liver and purification and down-sending of lung, liver and lung are outer circles of upward and downward movement, so they have antagonistic functions. Firth, by the relationships between upbearing the clear and down bearing the turbid of spleen-stomach and free coursing of liver, free coursing of liver-gallbladder is the essential requirement that it certify transportation and transformation of spleen-earth, so the disease of liver-gallbladder induce spleen-stomach disease pattern to affect its function of transportation and transformation. Fifth, by spleen and kidney, spleen yang is based on kidney yang, so the weakness of kidney yang can affect the function of transportation and transformation of spleen-stomach as it can't warm spleen earth. Sixth, by homogeny of liver-kidney, essence and blood of liver-kidney and ministerial fire of liver-kidney have mutal generation and limitation physiologically and they mutually are affected in pathologically.

Objectives : It was designed for making theoretical base about the relation of the Spleen, Stomach and the liver which could be used in clinic. Methods : Including Huang Di Nei Jing(黃帝內經), the 22 kinds of books written about the relation of the Spleen, Stomach and the Liver, and 2 kinds of papers were referenced. They were divided and studied according to physiology, pathology, meridian system and treatment. This study is focused on internal organ theory. Conclusion 1. In physiology, the Liver has the function of smoothing and regulating the flow of vital energy(Ki), while the Spleen is in charge of digestion and transportation. 2. In pathology, there can be informed disharmony of the Spleen, Stomach and the Liver, blood deficiency in the Liver and Spleen, jaundice, and bleeding etc. 3. In meridian system, the junction points of Spleen Meridian and Liver Meridian are Liv14, SP6, SP12, SP13. 4. In treatment, 1) If there is disharmony of the Liver and Spleen, the Liver must be soothed and the function of Spleen invigorated. 2) If there is disharmony of the Liver and Stomach, the Liver must be soothed and the function of Stomach invigorated.

Purpose: 99mTc-mebrofenin hepatobiliary scintigraphy (HBS) is an important and clinically useful diagnostic imaging study for detecting complications after liver transplantation. CT contrast agents due to their high atomic numbers, lead to a decrease in gamma ray count rates. This study investigated the impact of CT contrast agents on the uptake of 99mTc-mebrofenin in the liver. Materials and Methods: The quantitative HBS was performed on sixty-two liver transplantation patients (male:female=36:26), with a mean age of 59.4±6.4 years. Statistical comparison of hepatic uptake reduction ratio (HURR%) before and after the injection of CT contrast agents was performed using a paired t-test. Results: Hepatic uptake of the reduction ratio was 94.47±3.65% for the pre-CT contrast agents and 92.17±4.00% for the post-CT contrast agents. HURR% after CT contrast agent injection showed a statistically significant difference compared to before the injection (t=11.09, P<0.001). Conclusion: It will be necessary to pay attention when examining the HBS of patients with liver transplantation after the injection of CT contrast medium. It is advisable to schedule the examination on a different day to prevent residual contrast medium in the body from interfering with the quantitative evaluation of the nuclear medicine examination.

Objectives : Cancer is the second most frequent cause of death in Korea. Cancer screening tests can save lives through early detection. Enhancing the cancer screening rate is an important strategy for reducing cancer mortality. The purpose of our study was to evaluate the screening rate and related factors in a rural area. The study investigated relationships between sociodemographic characteristics, several preventive behaviors, and the experience of several cancer screening behaviors. Materials and Methods : The study population was recruited voluntarily from the three rural areas(Myen) in Chungju city. The participants completed structured questionnaire from July 21, 1990 to July 26, 1998. Results : The proportions of the study population who had previously received stomach, liver, breast, or cervix cancer screening tests were 24.5%, 18.5%, 27.0%, 59.2% respectively. The 1-year screening rates of stomach, liver, breast, and cervix cancer were 7.4%, 6.8%, 8.6%, 15.6% respectively. In multivariate logistic analysis, some sociodemographic variables, preventive behaviors, or psychological variables were significantly associated with several cancer screening tests. Those who had previously received a stomach cancer screening test were significantly associated with the presence of chronic disease, physician's recommendation, use of alcohol family history of cancer, or previous liver cancer screening test. Those who had previously received a liver cancer screening test were associated with education level, physician's recommendation and previous stomach cancer screening test. Those who had received a cervix cancer screening test were significantly associated with education level, presence of a transportation vehicle, physician's recommendation use of alcohol and previous breast cancer screening test. And those who had received a previous breast cancer screening test were significantly associated with age, marital status, and earlier cervix cancer screening test. Conclusion : Based on the results of this study a strategy to promote cancer screening and health objectives at the district level can be made.

The cytochrome P-450 enzymes (CYP 2A6) regulate many endogenous signaling molecules and drugs. Aryl alkynes such as 2-ethynylnaphthalene are important P450 inhibitors which have been extensively studied as medicines or as an effective chemical probes for profiling mouse liver microsomal P-450. Here we have synthesized indole-based novel P450 inhibitor, 5-ethynyl indole 3, and showed that it has successfully inhibited CYP 2A6 by chemical inhibition reaction. By using HPLC equipped with a photo diode array(PDA) detector, all of the peaks derived from the enzymatic reaction have been characterized.

In order to investigate the occurrence characteristics of cancer in terms of industry in Kwangju-Chonnam area, medical utilization records of industrial medical insurance corporations during the period of 1987 to 1988 were reviewed for the identification of neoplastic disease. The cases obtained from the medical records were followed up for the verification and to get additional information. Standardized incidence data were compared by occupational characteristics. Multiple logistic regression analysis was applied to analyze the difference of incidence or distribution of cancer as a whole or of some selected cancer. Total cases of cancer identified were 242 during the study period. Annual incidence rate was calculated as 123.1 per 100,000 person. The frequent types of cancer were cancers of stomach, liver, lung, colon and rectum, bladder and lymphoma in descending order. Employees of mine and other sand handling industries showed significantly higher risks for cancer of stomach and cancer as a whole. Employees of the transportation industry showed the higher risk for cancer of liver, Workers in small-sized industry (${\leqq}100$) had a higher risk for cancer than who in large-sized industry (<100). These findings suggested the effect of occupational environmental exposure to cancer development.

The aim of this study was to evaluate the antioxidant activity and protective effect of extracts from the stems and leaves of Chrysanthemum boreale (CBSL) on t-BHP induced oxidative stress in human liver cells (Chang cells). Antioxidant activities in the extracts were determined for various radical scavenging activities including ferric reducing antioxidant power, 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity, and oxygen radical absorbance capacity (ORAC). CBSL showed a very good scavenging effect of DPPH radical ($IC_{50}$ $0.009{\pm}0.002$ mg/mL), alkyl radical ($IC_{50}$ $0.004{\pm}0.001$ mg/mL), and hydroxyl radical ($IC_{50}$ $6.742{\pm}0.152$ mg/mL). CBSL also showed a strong antioxidant effect in the ORAC assay. In the MTT assay on human liver cells (Chang cells), the extracts showed protective effects by increasing cell viability, decreasing ROS, and restoring mitochondria membrane potential upon t-BHP induced oxidative stress. Our findings suggest that CBSL extracts are a potential therapeutic with protective antioxidant effects upon oxidative stress.

Objectives The purpose of this study is aimed at diagnosing and suggesting treatment plans for commonly seen clinical manifestation of heat symptom in the upper body and coldness in the lower body, also known as hot above, cold below syndrome. Methods Various reasons attribute to the presence of hot above, cold below syndrome, but mainly contributed by blockage of normal Qi flow by abnormality of heart-kidney root, spleen-stomach axis, and liver-lung axis. Diagnosing these abnormalities and timely alleviation to the healthy state is presented in the study. Results 1For heat in the upper body, Huang Lian Jie Du Tang(黃連解毒湯), CF, or JsD pharmacopuctures are injected on GB21, GB20. Qi stagnation in the thoracic area is treated with BUM injection on CV17. For impairment of transportation and transformation in the middle energizer, BUM pharmacopuncture is injected on CV12. Coldness in the lower energizer was relieved by bee venom or Sweet BV(Bee Venom free from enzymes) on CV6. Conclusion Above proposed methods of regulating water-fire were effective in treating hot above, cold below syndrome in clinical manifestations. But once the symptom subsides, treatment focused on eliminating innate cause should be rendered to achieve more successful results.

In this paper, to find out how different the treatment of special individuals named 'old people' is with that of ordinary cases, Dongeuibogam(東醫寶鑑) was chosen as the study material and some parts in it where the symptoms of old people in the same disease category were treated in different ways were excerpted to analyze the tendency of pathological symptoms and prescriptions in the physiological perspective. As the result of analysis on the parts in Dongeuibogam(東醫寶鑑) where the old people were treated in different ways, it turned out that 65 prescriptions were used in 24 pathological symptoms. The 24 symptoms are included mainly in chapters of 'inner view(內景)' and 'outer form(外形)'. They are including the pathological symptoms which had been presented as general geriatric symptoms and also seems to have added other symptoms which should be clinically reflected in the specialty of treatment for geriatric diseases. The 65 prescriptions are also recorded mainly in chapters of 'inner view(內景)' and 'outer form(外形)'. The herbs used for them were sweet and warm herbs such as Rehmannia glutinosa (Gaertner) Libosch(熟地黃), Angelica gigas Nakai(當歸), Panax ginseng C. A. Mey(人蔘) and Atractylodes macrocephala Koidz(白朮) that can support the essence blood of liver and kidney and the energy of spleen, lung and stomach. Those herbs could be added or subtracted according to the symptom. It seems to have resulted from the treatment method that old people was applied to old people in consideration of their physiological features. When the 24 symptoms and 65 prescriptions for geriatric diseases different from ordinary ones in Dongeuibogam(東醫寶鑑) were considered in the physiological view point, it could be seen that each pathological symptom was manifested as a exhaustion of kidney qi(腎氣枯渴) which was a characteristic physiologic state of old people. Through this, it could be seen that the use of prescriptions was also made to mitigate the body fluid deficiency(津液不足), the kidney yin inner heat(腎陰內熱), the heart spirit void and loss(心神虛損), the kidney yang deficiency(腎陽不足), the spleen failing in transportation(脾失健運), the spleen yang deficiency(脾陽不足), the liver fire inner movement(肝火內動) and the lung energy void and loss(肺氣虛寒).

In both deteministic user Optimal Traffic Assignment Model (UOTAM) and stochastic UOTAM, travel time, which is a major ccriterion for traffic loading over transportation network, is defined by the sum of link travel time and turn delay at intersections. In this assignment method, drivers actual route perception processes and choice behaviors, which can become main explanatory factors, are not sufficiently considered: therefore may result in biased traffic loading. Even though there have been some efforts in Stochastic UOTAM for reflecting drivers' route perception cost by assuming cumulative distribution function of link travel time, it has not been fundamental fruitions, but some trials based on the unreasonable assumptions of Probit model of truncated travel time distribution function and Logit model of independency of inter-link congestion. The critical reason why deterministic UOTAM have not been able to reflect route perception cost is that the route perception cost has each different value according to each origin, destination, and path connection the origin and destination. Therefore in order to find the optimum route between OD pair, route enumeration problem that all routes connecting an OD pair must be compared is encountered, and it is the critical reason causing computational failure because uncountable number of path may be enumerated as the scale of transportation network become bigger. The purpose of this study is to propose a method to enable UOTAM to reflect route perception cost without route enumeration between an O-D pair. For this purpose, this study defines a link as a least definition of path. Thus since each link can be treated as a path, in two links searching process of the link label based optimum path algorithm, the route enumeration between OD pair can be reduced the scale of finding optimum path to all links. The computational burden of this method is no more than link label based optimum path algorithm. Each different perception cost is embedded as a quantitative value generated by comparing the sub-path from the origin to the searching link and the searched link.
