Purpose : The enhanced cytotoxic effect of combined treatment of hyperthermia and chemotherapy by increasing intracellular acidity with HMA was investigated. Materials and Methods : FSall tumor cells were injected on the hindlegs of female C₃H mice. When the tumor volume reached about 200mm³, experiments were performed on the groups classified as follows : Group Ⅰ : Control. Group Ⅱ : Melphalan alone (2.5mg/kg, 5mg/kg, 10mg/kg, 15mg/kg). Group Ⅲ : Heat alone (42.5°C for 1 hour). Group Ⅳ : Mephalan + Heat (42.5°C for 1 hour). Group Ⅴ : HMA(10mg/kg) + Melphalan(5.0mg/kg) + Heat(42.5°C for 1 hour). Each group included 8-12 mice on each experiment. HMA (3-amino-6-chloro-5-(1-homopiperidyl)-N-(diaminomethylene)-c-pyrazinecarboxamide). an analog of amiloride which increases intracellular pH(pHi) was dissolved in dimethyl sulfoide (DMS) and injected tnto the tumor-bearing mice through the tail vein. 10mg/kg of HMA and each dose of mephalan were injected into peritoneum of the tumor-bearing mice 30 minutes before heating. Tumor growth delay was calculated when the tumor volme reached at 1500mm³. Excision assay was performed on each group and repeated 2-4 times. Results : Tumor growth delay of each experimental group at 1500mm³ were 9, 10, 13 and 19 days respectively. In vivo-in vitro excision assay using FSall tumor cells, the mytotoxicity of each experimental groups was 1.2X10⁷, 1X10⁷, 6X10⁶, 1.7X10⁶ and 1X10⁵ clonogenic cells/gm respectively. When HMA was added to the combined treatment of heat and chemotherapy, the tumor growth was delayed more than combined treatment without HMA i.e., 6 days tumor growth delay at 1500mm³ of tumor volume. conclusion : The combined effect of cytotoxicity by heat and chemotherapy can be much more enhanced by HMA.

Ethanol extracts of Mung Bean seeds and seedings were analysed by 2-dimensional and circular paper partion chromatography for Nitrogen compounds as a part of the study on the Amino acids metabolism. In the seeds, 18 ninhydrin positive substances were present, before germination, but the number increased to 21 after germination. There were 3 unknown substances and one of it formed newly after germination. After 2-days germination, the amount of amides, such as Asparagine and Glutamine. where increased very large which were very small amount before it. Those were accumulated more in dark place than in light and the amount of Asparigine were more than that of Glutamine. Through the germination, there were large amount of Glutarmic acid, Aspartic acid and Alanine which seems to be concerned in transamination reaction in seedings. Valine, Leucine, and Phenylalanine increased to considerable amount after germination. This is very remarkable fact as those Amino acids were reported to be concerned in transamination reaction recently. ${\gamma}$-amino butyric acid was detected in both Cotyledon and Embroy through the germination. It seemed that there is no any Nitrogen Metabolism in the unbroken seed even if it is preserved very long period.

A ninhydrin positive substance(formed during germination of Mung Bean) which on a 2-dimensional chromatography(BuOH-HAc, and$ PhOH-NH_2$ gave a spot above glutamic acid was isolated by cutting out the appropriate spot on the paper and extracting the paper with water. Hydrolysis of this substance with $2N H_2SO_4\;or\;3N\;HCl\;at\;120^{\circ}C$ for 15 hours gave the spot of mainly glutamic acid, alanine and very faint of glycine and cysteine on a paper chromatography. It is suggested that the reaction of ${\gamma}$-glutamyl-cysteinecyl-glycine + L-alanine in the presence of ${\gamma}$-glutamyle transferase ${\rightarrow}$ ${\gamma}$-glutamyl-alanine + cysteinyl-glycine, takes place in germinated Mung Bean.

The Purpose of Study 1. Inspection of clinical application on TCD to CVA 2. Objective Comparement and analysis about treatment effect of Western-Medicine, Korean Medicine, Cooperative consultation of Korean and Western medicice for CVA The Subject of Study We intended for the eighty six patient of CVA who had been treated in the Oriental Medical Hospital at Dong Eui Medical Center from 1997. 8. I to 1998. 7. 31 1. View of CT, MRI : the patient of Cb infarction 2. Attack Time : The patient who coming hospital falling ill within the early one week The method of study 1. Treat four group of Korean medicine, Constitution medicine, Western medicine, cooperative consultation of Korean medicine and Western medicine. 2. Application of TCD Check the result for three times, immediatly after the attack, two months later, four months later 3. Comparative analysis of each treatment effect by clinical symptoms and pathologic examination 4. The Judgement of the patient The Result From 8/1/1997 to 7/31/1998, We have the following result by clinical analysis intended for CVA 86 patients who had been treated in the Oriental Medical Hospital at Dong Eui Medical Center from 1997. 8. 1 to 1998. 7. 31 in 1. Analysis according to Age The first stage of thirties, forties, seventies is heavier than forties, fifties in improvement and Index of improvement of symptom 2. Analysis according to sex We have no special relation in an average of symptom and improvement, Index improvement 3. Analysis according to Family History We have the better result in first stage and improvement, index improvement when no family history. 4. Analysis according to Past History We have no special relation in past history like hypertension, DM, heart problem 5. Analysis devided two group, above group and under group on the basis of the average in first stage of all patient. We have the better result when the first stage is light, that the first score of barthel index and CNS is high. 6. Analysis of the effect of treatment about Korean medical treatment, Western medical treatment, cooperative treatment. In this study, the highest group of rate of treatment at four contrast groups (Korean medicine, Constitution medicine, Western medicine, cooperative treatment according to dyagnosis and range of treatment was the patient group of doing dyagnosis and method of treatment based on constitution medicine theory. This is that of doing demostation, A-Tx, po-herb-medication according to dyagnosis and treat method of constitution of Lee Je-ma In case of left, the case of dyagnosis any disease according to doctor view but, normal in TCDwas 22-beginning of attack, 20- two weeks later, 11 case-four weeks later in case of right, 15-beginning of attack, 12-two weeks later, 9 case four weeks later. So left vessel compares to right vessel is more interference, in fact more than a 1/2 of the patients of MCA disease can't do dyagnosis. In rate of imparement, the state of pacient improved but there isn't the improved case of result in TCD. 7. In TCD dyagnosis, between the case of inconsus the doctor view specially MCA in brain blood vessel is in large numbers and in total 86's patient, impossible case of dyagnosis according to interferiance of temporal is 21 case. 7. Result study about application of Kreaan medical treatment 1) The impossible patient of observation MCA blood vescular for interference temporal bone happened in large numbers. 2) There is the case having difference result to CT,MRI, MRA result. 3) Because individual difference is large, excluding to ananalogy of symptom. This is normal numerical value that has possibility of being checked as abnormal numerical value 4) there are a lot of cases that the speed of normal part is as similarly measured as that of abnormal part. It means that we cannot judge the disease by this measure 5) It is rare that this measure represent degree of improvement in patient's condition of disease. When we observe patient's condition become better, but w

목 적 : SCK 선암 세포주에서 방사선 조사에 의해 일어나는 apoptosis와 세포 주기와의 연관성을 규명하고자하였다. 대상 및 방법 : SCK 선암 세포주를 apoptosis의 통상적인 정성 분석 방법인 agarose gel electrophoresis 방법을 이용하여 방사선 조사량과 배지 pH 환경과의 연구에서 2-12Gy의 방사선 조사량과 pH 7.5 및 6.6의 배양 배지 조건하에서 다양한 배양 시간의 경과에 따른 DNA fragmentation의 지표인 laddering을 관찰하였다. 실험 조작으로 apoptosis가 유발된 세포군을 정량적으로 분석하고 세포 주기 분석을 위해 FACScan을 이용하였다. 결 과 : apoptosis가 왕성히 발현되었던 pH 7.5 배지에서 배양하였던 세포에서는 방사선 조사직후부터 G2/M phase의 세포들의 분획이 증가하기 시작하여 12시간째 약 70%까지의 최고치를 보인 후 36시간째에 방사선을 조사하지 않았던 상태의 분획으로 정상화되었다. 하지만 pH 6.6 배지에서 배양하였던 세포에서의 G2/M phase의 세포들의 분획의 증가는 pH 7.5 배지에서 배양하였던 세포들에 비해 비교적 천천히 일어나고 그 최고치도 24시간째에 약 45%로 관찰되었다. 특이한 것은 G2/M phase의 세포들의 분획이 그 이후 감소되는 정도가 pH 7.5 배지에서 배양하였던 세포들에 비해 미약하여 48시간 배양 이후에도 약 30-35%의 세포는 G2/M phase의 세포들의 분획으로 관찰되었다. 결 론 : 연구자들은 이러한 현상이 세포들이 G2/M phase에서 많은 양의 세포들이 집적되어 세포주기를 순환하지 못하는 G2/M arrest 현상으로 이해하였다. 세포 내외의 산성환경 상태에서 방사선을 조사 받은 SCK 종양세포는 G2/M arrest 상태가 지속되며 이는 post- mitotic apoptosis를 억제한다고 추론하였다. Purpose : The relationship between environmental pH on the radiation induced-apoptosis in SCK mammary adenocarcinoma cells and cell cycle dependence was investigated. Material and Methods : Mammary adenocarcinoma cells of A/J mice(SCK cells) in exponential growth phase were irradiated with a 137Cs irradiator at room temperature. The cells were irradiated 1 hour after the media was replaced with fresh media at a different pHs. After incubation at 37℃ for 0-48 h, the extent of apoptosis was determined using agarose gel electrophoresis and flow cytometry. The progression of cells through the cell cycle after irradiation in different pHs was also determined with flow cytometry. Results : The induction of apoptosis by irradiation in pH 6.6 medium was markedly less than that in pH 7.5 medium. When the cells were irradiated and maintained in pH 7.5 medium, the percentage of cells in G2/M phase rapidly increased to about 70% at 12 h after an exposure to 12Gy and returned to control level by 36 h. The percentage of cells in G1 phase decreased as the percentage of cells in G2/M increased. On the other hand, in pH 6.6 medium the percentage of cells in G2/M phases gradually increased to about 45% at 24 h after 12Gy irradiation and then slowly recessed and consequently, as much as 30-35% of the cells were still in the G2/M phase 48h after irradiation. The percent age of cells in G1 phase then increased as the G2/M arrest began to recede. The radiation-induced G2/M arrest in pH 6.6 medium lasted markedly longer than that in pH 7.5 medium. Conclusion : Radiation-induced apoptosis in SCK tumor cells are reversely suppressed in an acidic environment. Radiation-induced G2/M arrest is prolonged in an acidic environment indicating that the suppression of radiation- induced apoptosis and prolongation of radiation-induced G2/M arrest in an acidic environment are related.

Purpose : To investigate the effect of aqueous extract of Ganoderma lucidum(G.I.) on the survival of tumor cells in vitro and on the growth of tumors in vivo. Materials and Methods : Dried G.I. was made into powder extracted with distilled water filtered and diluted from a maximum concentration of 100mg/ml in sequence. The cytotoxicity of G.I. in vitro was evaluated from its ability to reduce the clonogenicity of SCK tumor cells. For the tumor growth delay study, about 2X10⁵ of SCK tumor cells were subcutaneously inoculated in the legs of a/J mice. The first experimental group of mice were injected i.p. with 0.2ml of 250mg/kg of G.I. from the first day after tumor inoculation for 10 days. The second experimental group of mice were injected i.p. with 0.2ml of 250mg/kg of G.I. either once a day for 10 days or twice a day for 5 days beginining from the 7th day after tumor inoculation Results : 1. Cytotoxicity in vitro; survival fraction, as judged from the curve, at G.I. concentration of 0.5, 1, 5, 10, 25, 50 and 100mg/ml were 1.0, 0.74±0.03, 0.18±0.03, 0.15±0.02, 0.006±0.002, 0.015 and 0.0015 repectively. 2. Tumor growth delay in vivo; a) the time required for the mean tumor volume to grow to 1,000mm³ was 11days in the control group and 14days in the experimental group. b) the time required for tumor volume to increase 4 times was 11 days in the control group while it was 10,5 and 12 days in the groups injected with G.I. once a day and twice a day from the 7th day after tumor inoculation respectively. Conclusion : Aqueous extracts of G.I. showed a marked cytotoxicity on the SCK mammary cells in vitro. Tumor growth delay was statistically significant when G.I. injection was started soon after tumor inoculation but it was not significant when injection was started after the tumors were firmly established.

변형된 치관부 파절편 재부착술식을 이용한 치관치근파절의 치료

치관부 파절편 재부착술식은 접착치의학의 발달과 더불어 치관파절 치료 방법 중 하나로 자리매김하였다. 하지만 치관치근파절된 치아에 있어서 기존의 치관부 파절편 재부착술식으로는 치은연하 영역의 수복 및 생물학적 폭경의 유지가 어려워 부가적인 치관연장술 또는 치아 정출술 등이 요구되게 된다. 하지만 이번 증례보고는 치수노출을 동반한 치관-치근파절을 치료함에 있어서 이러한 부가적인 술식 없이 변형된 치관부 파절편 재부착술식만을 이용하여 처치한 사례이다. 환자는 근관치료 후 post 삽입 및 재부착 술식을 시행 받았으며 이때 치관 파절편의 변형을 통해 생물학적 폭경을 위한 공간 유지 및 적절한 접착을 위한 영역을 확보할 수 있었고 이후 한차례의 재파절이 발생하였지만 재차 재부착 후 2년간의 follow up을 통해 치주부착상실 없이 치관 파절편이 잘 유지되는 것이 관찰되었다. The development of adhesive dentistry has allowed that the crown fragment reattachment can be another option in the treatment of crown fracture. However, additional crown lengthening procedure or extrusion of the tooth may be necessary in the treatment of crown root fracture because subgingival fracture line in close proximity to the alveolar bone leads to challenges for restorative procedure and the violation of the biologic width. This case report presents a modified crown fragment reattachment technique of crown root fracture with pulp exposure, which was done without additional crown lengthening procedures. After the endodontic treatment, the patient was treated using a post insertion and the fragment reattachment technique, which made it possible to preserve the space for the biologic width and maintain a dry surgical field for adequate adhesion through the modification of the fractured coronal fragment. Since a coronal fracture was occurred and reattached afterward, it was observed that the coronal fragment was well maintained without the additional loss of periodontal attachment through 2-year follow up.
