We report a case of microcystic meningioma which showed unusual radiological findings resembling malignant tumor. A 44-year-old woman presented with generalized tonic clonic seizure and right hemiparesis. Computed tomography and magnetic resonance images showed a mass at left frontal, parasagittal area with septa-like enhancement and surrounding edema. 201Tl SPECT showed focal uptake in mass lesion which suggests the malignant tumor. The histopathological findings of this tumor revealed to be a microcystic meningioma and Ki-67 labeling index was 3.8. Although the mass was a subtype of meningioma, it showed a early recurrence 10 months after grossly total resection because of high proliferative index. We suggest that the biological behaviour in addition to morphologic classification should be considered in the management of benign brain tumor, such as meningioma.

To make a objective diagnosis of the syndrome of cold-limbs, We investigated the 20 patients with cold limbs and GI trouble and 20 normal people as a control group. And we compared the thermal difference between Chon-jung(CV17) and Chung-wan(CV12 中脘), Chon-jung(CV17) and Ki-hae(氣海 CV6) and we compared the thermal differences of No-gung(PE8 勞宮) and Yong-chon(湧泉 KI1), too. The results were as follows. 1. All 20 patients had GI trouble and cold limbs. They had the symptom-Indigestion(16 cases-80%) with heart burn, tympanites, abdominal distention, hiccup, belching. Beside that symptom they also had constipation(6 cases-30%), diarrhea(3 cases-15%), headache & dizziness(6 cases-30%). And some had the menstrual syndrome, chronic fatigue, palpitation, insomnia, edema, arthralgia. 2. The thermal difference of the palms between the patients group and the control group were $25.70^{\circ}C,\;25.82^{\circ}C$, but they were not significant. 3. The thermal difference of the soles between the patients group and the control group were $23.58^{\circ}C,\;24.42^{\circ}C$ and the significancy was P=0.020 so it was significant(P<0.05). 4. The thermal difference of the palms and Chon-jung(CV17) between the patients group and the control group were $1.08^{\circ}C,\;0.76^{\circ}C$, but they were not significant. 5. The thermal difference of the sales and Chon-jung(CV17) between the patients group and the control group were $3.01^{\circ}C,\;1.90^{\circ}C$ and the significancy was P=0.003 so it was significant(P<0.05). 6. The thermal difference of Chon-jung(CV17) and Chung-wan(CV12 中脘) between the patients group and the control group was $0.30^{\circ}C,\;0.62^{\circ}C$ and the significancy was P=0.793 so it was significant(P<0.05). 7. The thermal difference of Chon-jung(CV17) and Ki-hae(CV6 氣海) between the patients group and the control group was $0.53^{\circ}C,\;0.68^{\circ}C$, but they were not significant. From the above, I could find the significance of D.I.T.I to diagnose the cold-feet not the cold-hands and the thermal difference between the trunk and limbs was more significant on cold-feet than on cold-hand, either.

Purpose: ACR (American College of Radiology) offers variable parameters to PET/CT quality control by using ACR Phantom. ACR Phantom was made to evaluate parameters which are uniformity, attenuation, scatter, contrast and resolution. Manual analysis method wasn't good for the use of QC because values of parameter were changed as it may user and it takes long time to analysis. Ki-Chun Lim, a nuclear scientist in AMC, developed program that automatically analysis values of parameter by using ACR Phantom to overcome above problems. In this study, we evaluated automatic analysis program's usability, through the comparing SUV of each method, reproducibility of SUV when repeated analysis and the time required. Materials and Methods: Using Flangeless Esser PET Phantom, the ideal ratio of 4 : 1 hot cylinder and BKG but it actually showed a ratio of 3.89 to 1 hot cylinder and BKG. SIEMENS Biograph True Point 40 was used in this study. We obtained images using ACR phantom at Fusion WB PET Scan condition (2 min/bed) and 120 kV, 100 mAs CT condition. Using True X method, 3 iterations, 14 subsets, Gaussian filter, FWHM 4 mm and Zoom Factor 1.0, $168{\times}168$ image size. We obtained Max. & Min. SUV and SUV Mean values at Cylinder (8, 12, 16, 25 mm, Air, Bone, Water, BKG) by automatic program and obtained SUV by manual method. After that, we compared manual and automatic method. we estimate the time required from opened the image data to final work sheet was completed. Results: Automatic program always showed same result and same the time required. At 8, 12, 16 and 25 m cylinder, manual method showed 6.69, 3.46, 2.59, 1.24 CV values. The larger cylinder size became, the smaller CV became. In manual method, bone, air, water's CV were over 9.9 except BKG (2.32). Obtained CV of Mean SUV showed BKG was low (0.85) and bone was high (7.52). The time required was 45 second, 882 second respectably. Conclusions: As a result of difference automatic method and manual method, automatic method showed always same result, manual method showed that the smaller hot cylinders became, the lager CV became. Hot cylinders mean region size, the smaller hot cylinder size becomes we had some trouble in doing ROI poison setting. And it means increase in variation of SUV. The Study showed the time required of automatic method was shorten then manual method.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Existing web-based education systems have been used with a secondary tool for learning a regular curriculum in school. Inspite of many banifits as unrestrictions of time and space, they are still not proper to use as an component of regular curriculum during lecture. In this paper, we design and implement the web-based science education system for a middle school. Our system can be used by teachers in the classroom-lecture as well as by each student in their homes.

<P>Benzyl isothiocyanate (BITC) is a hydrolysis product of glucotropaeolin, a compound found in cruciferous vegetables, and has been shown to have anti-tumor properties. In the present study, we investigated whether BITC inhibits the development of prostate cancer in the transgenic adenocarcinoma mouse prostate (TRAMP) mice. Five-week old, male TRAMP mice and their nontransgenic littermates were gavage-fed with 0, 5, or 10 mg/kg of BITC every day for 19 weeks. The weight of the genitourinary tract increased markedly in TRAMP mice and this increase was suppressed significantly by BITC feeding. H and E staining of the dorsolateral lobes of the prostate demonstrated that well-differentiated carcinoma (WDC) was a predominant feature in the TRAMP mice. The number of lobes with WDC was reduced by BITC feeding while that of lobes with prostatic intraepithelial neoplasia was increased. BITC feeding reduced the number of cells expressing Ki67 (a proliferation marker), cyclin A, cyclin D1, and cyclin-dependent kinase (CDK)2 in the prostatic tissue. <I>In vitro</I> cell culture results revealed that BITC decreased DNA synthesis, as well as CDK2 and CDK4 activity in TRAMP-C2 mouse prostate cancer cells. These results indicate that inhibition of cell cycle progression contributes to the inhibition of prostate cancer development in TRAMP mice treated with BITC.</P>

The objective of this research is to find out the influencing factors to recur oral cancers. The outcomes of 85 patients(male: 62 patients, female: 23 patients) with oral cancer who were not treated any pre-operative radiotherapy, chemotherapy or previous oral surgery, other than routine dento-alveolar procedures and a recent diagnostic biopsy were analysed retrospectively. Actuarial (life tables) survival analysis showed the 5 year survival rate was 58%, 52% for male patients, 72% for female patients. The patients who were under 50 years old showed 71% of 5 year survival rate, 51% of 5 year survival rate were above 51 years old group. Patients who were treated with elective neck dissection showed better prognosis which were shown 73% of 5 year survival rate than not neck dissection which were reveal 45% of 5 year survival rate. In TNM stage of patients, advanced stage showed worse prognosis, but only N stage did not suggest to judge good prognosis. Most patients were treated under postoperative radiation therapy and showed better prognosis.

本 硏究는 濟州道에서 燐酸施肥量差異가 靑刈豌豆의 主要 形質과 收量에 미치는 影響을 究明하기 위하여 濟州在來豌豆와 Sparkle을 供試하여 1998年 3月부터 5月까지 修行하였으며 試驗한 結果를 要約하면 다음과 같다. 1. 開花日數는 燐酸施肥量이 많아짐에 따라 늦어지는 傾向이었다. 品種問의 開花日數는 濟州在來豌豆가 빨랐고, Sparkle은 늦은 편이었다. 2. 草長은 燐酸施肥量이 많을수록 길었으며, 品種間에는 各 處理區에서 濟州在來豌豆가 길었고, Sparkle은 짧았다. 3. 莖直經, 主莖節數는 濟州在來豌豆 Sparkle 두 品種 供히 燐酸施肥量이 增加할수록 增加하였다. 4. 10a當 靑刈收量은 두 品種 모두 燐酸施肥量이 많아짐에 따라 漸次的으로 增加되는 傾向이었다. 5. 濟州求來談臺의 草長과 靑刈收量과는 高度로 有意한 正의 相關을, Sparkle은 正의 相關關係가 있어서 두 品種 모두가 草長이 길수록 靑刈收量이 많았다. Two pea cultivars, 'Cheju local pea' and 'Sparkle', were planted on 3 March at Cheju at 5 phosphate rates(0, 5, 10, 15, 20kg/10a) to determine the optimum phosphate fertilization rate. Days to flowering increased as phosphate rate was increased. Days to flowering of Cheju local pea was earlier than that of Sparkle. The more phosphate rate, the higher plant height Plant height of cultivar Cheju local pea was taller than of Sparkle. As phosphate rate was increased, stem diameter and number of nodes per plant of two cultivars increased. Fresh forage yield of two cultivars linearly increased as phosphate rate was increased from 0 to 20kg/10a. Plant height for each cultivar was positively correlated with fresh forage yield.

ABSTRACT This study was accomplished to look into the response of main growth characters, yield and chemical composition of Cheju local cowpea on Cheju Island based on the difference between seeding rate. The study took place between May and September, 1998. Number, of days to flowering tended to be delayed as the seeding rate increased. Plant length was the longest at 6kg/10a treatment and the next one was at 5kg/10a treatment. The shortest came from 2kg/10a treatment, 275 cm, 271 and 220cm respectively. Number of branchs and stem diameter became weaker as the seeding rate increased. Fresh forage yields per lOa was the heaviest which weighed 6,073kg at 6kg/10a treatment and 5,840kg at 5kg/10a treatment respectively. The rest decreased gradually. Dry matter yields per lOa, crude protein yields per lOa and total digestible nutrient yields per lOa showed a similar tendency to fresh yields per lOa. The percentage of crude protein and crude fat got higher as the seeding rate increased, but the percentage of crude ash and crude fiber rather tended to decrease. Nitrogen free extract and total digestible nutrient percentages were similar to the change of crude protein percentage. SPAD reading values were the highest at 6kg/10a and 5kg/10a treatment.
