  • Here we described 8 patients treated with acupuncture and moxiburstion due to chronic postoperative pain as a comlication of gastrointestinal surgery. The patients were suffering from pain that continued for more than 6 months after laparotomy for gastric cancer (n=1), rectal cancer (n=2), cholangiocarcinoma (n=2), hepatocellular carcinoma (n=2) and ischemic colitis (n=1), respectively. Mean time elased from surgery were 31.25(${\pm}21.72$)months, pain grade on first visit by VAS(visual analogue scale, 0~10mm) was 3.75(${\pm}0.97$)point, and acupuncture and moxiburstion were performed 12.63(${\pm}5.74$)times during 5.5(${\pm}2.4$)weeks, on average. At the end of treatment, pain was decreased 2.75(${\pm}0.97$)point compared to first visit. Based on the that results, it is reasonable to assume that acupuncture and moxiburstion can be effective to persistent post-surgical pain after laparotomic gastrointestinal surgery, at least to some laparotomized patients.

  • To examine the relationship between air pollution and occurrence of disease in plants, we investigated the alteration of physiology and biochemistry of Ginkgo biloba by inoculating with Coniothyrium sp. and fumigating with 0.1 ${\mu}l/l\;SO_{2-}$ Visual damage did not appear but photosynthesis, $CO_2$ use efficiency(CUE) and water use efficiency(WUE) were reduced when G. biloba was exposed to $SO_{2-}$for 7days (8 hours a day). When inoculated with Coniothyrium sp., the seventies of damage in G. biloba showed a threefold difference between $SO_{2-}$ treatment (SI) and $SO_{2-}$ free treatment (SFI) at day 42 from initial inoculation. Little difference was observed in sugar contents that may be used pathogens feed, among control, SFI and SI. In spite of the reduction in photosynthetic rate, sugar contents and CUE were maintained. WUE was enhanced 13% more at SI than SFI. The $CO_2$fixation boosted because of enhanced WUE, and thus sugar synthesis was not affected. In addition, sugar transport seems to be retarded for some internal alteration. Consequently, the severity of SI was more serious than that of SFI because Coniothyrium sp. easily invades into the physical texture of G. biloba weakened by $SO_2$ fumigation and because sugar was accumulated in leaves of G. biloba.

  • Knowledge which is represented by formal logic are widely used in many domains such like artificial intelligence, information retrieval, e-commerce and so on. And for medical field, medical documentary records retrieval, information systems in hospitals, medical data sharing, remote treatment and expert systems need knowledge representation technology. To retrieve information intellectually and provide advanced information services, systematically controlled mechanism is needed to represent and share knowledge. Importantly, medical expert's knowledge should be represented in a form that is understandable to computers and also to humans to be applied to the medical information system supporting decision making. And it should have a suitable and efficient structure for its own purposes including reasoning, extendability of knowledge, management of data, accuracy of expressions, diversity, and so on. we call it ontology which can be processed with machines. We can use the ontology to represent traditional medicine knowledge in structured and systematic way with visualization, then also it can also be used education materials. Hence, the authors developed an Shanghanlun ontology by way of showing an example, so that we suggested a methodology for ontology development and also a model to structure the traditional medical knowledge. And this result can be used for student to learn Shanghanlun by graphical representation of it's knowledge. We analyzed the text of Shanghanlun to construct relational database including it's original text, symptoms and herb formulars. And then we classified the terms following some criterion, confirmed the structure of the ontology to describe semantic relations between the terms, especially we developed the ontology considering visual representation. The ontology developed in this study provides database showing fomulas, herbs, symptoms, the name of diseases and the text written in Shanghanlun. It's easy to retrieve contents by their semantic relations so that it is convenient to search knowledge of Shanghanlun and to learn it. It can display the related concepts by searching terms and provides expanded information with a simple click. It has some limitations such as standardization problems, short coverage of pattern(證), and error in chinese characters input. But we believe this research can be used for basic foundation to make traditional medicine more structural and systematic, to develop application softwares, and also to applied it in Shanghanlun educations.

  • Tissue plasminogen activator (tPA) is a serine protease catalyzing the proteolytic conversion of plasminogen into plasmin, which is involved in thrombolysis. During last two decades, the role of tPA in brain physiology and pathology has been extensively investigated. tPA is expressed in brain regions such as cortex, hippocampus, amygdala and cerebellum, and major neural cell types such as neuron, astrocyte, microglia and endothelial cells express tPA in basal status. After strong neural stimulation such as seizure, tPA behaves as an immediate early gene increasing the expression level within an hour. Neural activity and/or postsynaptic stimulation increased the release of tPA from axonal terminal and presumably from dendritic compartment. Neuronal tPA regulates plastic changes in neuronal function and structure mediating key neurologic processes such as visual cortex plasticity, seizure spreading, cerebellar motor learning, long term potentiation and addictive or withdrawal behavior after morphine discontinuance. In addition to these physiological roles, tPA mediates excitotoxicity leading to the neurodegeneration in several pathological conditions including ischemic stroke. Increasing amount of evidence also suggest the role of tPA in neurodegenerative diseases such as Alzheimer's disease and multiple sclerosis even though beneficial effects was also reported in case of Alzheimer's disease based on the observation of tPA-induced degradation of $A{\beta}$ aggregates. Target proteins of tPA action include extracellular matrix protein laminin, proteoglycans and NMDA receptor. In addition, several receptors (or binding partners) for tPA has been reported such as low-density lipoprotein receptor-related protein (LRP) and annexin II, even though intracellular signaling mechanism underlying tPA action is not clear yet. Interestingly, the action of tPA comprises both proteolytic and non-proteolytic mechanism. In case of microglial activation, tPA showed non-proteolytic cytokine-like function. The search for exact target proteins and receptor molecules for tPA along with the identification of the mechanism regulating tPA expression and release in the nervous system will enable us to better understand several key neurological processes like teaming and memory as well as to obtain therapeutic tools against neurodegenerative diseases.

  • The purpose of this study is the develop a questionnaire for measuring Yin-Deficiency and examine the reliability and validity for its' value as a barometer for evaluating Yin-Deficiency. Questionnaire was developed according to the symptoms of Yin-Deficiency suggested in the 'Standardization of diagnostic terms and requirements of Korean Medicine', With and as a reference, each symptom has been worked on to be put on the questionnaire. Visual analogue scales(VAS) was used as a barometer for measuring frequency of manifestation of symptoms. A study was performed to measure validity and reliability of the final questionnaire for analysis. reliability of YinDQ was measured by Cronbach's alpha coefficient and test-retest method. This study utilized factor analysis and clinical validity for evaluation of validity. For the purpose of decreasing the amount of data-the number of factors, and at the same time minimize the loss of information factor analysis was performed Component factors were extracted using Principal Component Analysis. This study evaluated the clinical validity for examination of difference between the normal group and the patient group. Evaluation on the's internal consistency showed strong internal consistency with value of 0.8615. reliability from test-rest with three-week interval, followed by comparisons of the correlation coefficient and mean values of each item between the two. The Spearman correlation coefficient was 0.54-0.79. By factor analyse two factors with Eigen value of greater than 2.2 were selected. Factor 1 consists of items of 'irritable fever on the five Hearts', 'flushing of the zygomatic region in the afternoon', 'tidal fever', 'night sweats', and 'dryness on the mouth or the throat'. Factor two consists of items of 'emaciation', 'dizziness', 'insomnia', 'decreased amount of urine with yellowish color', and 'constipation'. The comparison between the patient group and the normal group showed significant differences for every ten questions. The results implies that YinDQ is a barometer with sufficient reliability and validity. The questionnaire for Yin-Deficiency may not be enough to replace the specific differential diagnosis by a doctor of Oriental medicine. Nevertheless, it can be effectively utilized as an assisting method in consultation or a method of measuring the degree of Yin-Deficiency in a group.

  • The objective of this study was to externally validate a new dosing scheme for busulfan. Thirty-seven adult patients who received busulfan as conditioning therapy for hematopoietic stem cell transplantation (HCT) participated in this prospective study. Patients were randomized to receive intravenous busulfan, either as the conventional dosage (3.2 mg/kg daily) or according to the new dosing scheme based on their actual body weight (ABW) ($23{\times}ABW^{0.5}mg\;daily$) targeting an area under the concentration-time curve (AUC) of $5924{\mu}M{\cdot}min$. Pharmacokinetic profiles were collected using a limited sampling strategy by randomly selecting 2 time points at 3.5, 5, 6, 7 or 22 hours after starting busulfan administration. Using an established population pharmacokinetic model with NONMEM software, busulfan concentrations at the available blood sampling times were predicted from dosage history and demographic data. The predicted and measured concentrations were compared by a visual predictive check (VPC). Maximum a posteriori Bayesian estimators were estimated to calculate the predicted AUC ($AUC_{PRED}$). The accuracy and precision of the $AUC_{PRED}$ values were assessed by calculating the mean prediction error (MPE) and root mean squared prediction error (RMSE), and compared with the target AUC of $5924{\mu}M{\cdot}min$. VPC showed that most data fell within the 95% prediction interval. MPE and RMSE of $AUC_{PRED}$ were -5.8% and 20.6%, respectively, in the conventional dosing group and -2.1% and 14.0%, respectively, in the new dosing scheme group. These findings demonstrated the validity of a new dosing scheme for daily intravenous busulfan used as conditioning therapy for HCT.

  • The pulmonary alveolar macrophage is thought to play an important role in the mediation of acute inflammatory lung injury by secretory products including degraded enzymes, cytokines, and reactive oxygen metabolites . This study was conceived to understand the role of alveolar macrophage in oxidative stress induced acute lung injury. To examine the alveolar macrophages and xanthine oxidase (XO) activity in bronchoalveolar lavage fluid (BALF), time-dependent changes of numbers of alveolar macrophages, monocytes and neutrophils in alveolar cavity were counted in association with ultrastructural and cytochemical observations of lung tissue and alveolar cells. The number of monocytes was increased (p<0.001) at 1h after IL-1 treatment compared with that of sham. At 2h after instillation of IL-1, the number of alveolar macrophages was the highest, XO activity in BALF was elevated at 2h after IL-1 instillation and the activity was markedly elevated(p<0.05) at 3h after IL-1 treatment. On the basis of these experimental results, it is suggested that, during early phase of acute lung injury induced by IL-1, alveolar macrophage-derived XO contributes to lung injury earlier than the neutrophilic respiratory burst.

  • This study was aimed to identify the effect of abdominal moxibustion on premenstrual syndrome and dysmenorrhea in university students. The data were collected by using questionnaires from April 25, 2005 to June 20, 2005. The subjects were university students from in the Pusan metropolitan area who had complained of menstrual discomfort. Thirteen students were assigned to the experimental group and fourteen students to the control group. The research design of this study was a nonequivalent control group pretest-posttest design. In the research method pretest were conducted through measurement based on scores of general character, menstrual character, premenstrual syndrome and dysmenorrhea in the experimental group and the control group. Experimentation was conducted by abdominal moxibustion being applied on the kwan-won hole and Ki-hae hole for 25 minutes at a time, three times a week, form the ending of one menstrual cycle to the beginning of the next menstrual cycle were in the experimental group. After treatment was finished, post tests conducted through measurement based on scores of premenstrual syndrome and dysmenorrhea in the experimental group. The control group conducted a point of same time and same measurement with the experimental group. The instruments used in this study MDQ(Menstual Distress Questionnaire) developed by moos(1968) and the VAS(Visual Analogue Scale) developed by Cline(1992). The data were analysed by SPSS/ win 12.0 program with ${\chi}$2-test and t-test to verify identification among subjects' general characteristics and menstrual characteristics. Hypothesis verification was analysed with t-test. The results of the study are as follows: The hypothesis, 'the experimental group who received abdominal moxibustion will decrease premenstrual symptoms more than the control group', was supported (t= -2.121, p=.022). The hypothesis, 'the experimental group who received adbominal moxibustion will decrease dysmenorrhea compared to the control group', was supported (t=-4.424, p=.001). As a result of this study, abdominal moxibustion will be used as a nursing aide to improve and prevent menstrual discomfort of university students who have premenstrual syndrome and dysmenorrhea.
