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.

MC₃T₃-E₁골아세포군을 이용하여 IGF-Ⅰ과 Ⅱ를 투여하고 DNA합성과 골아세포기능을 측정하기 위해 PTH에 대한 C-AMP반응정도, alkaline phosphatase 활성도를 측정하여 다음과 같은 결과를 얻었다. 1) IGF-Ⅰ과 Ⅱ는 모두 DNA합성이 어느 농도까지는 증식효과를 나타내지만 그 이후에는 억제되는 양상을 보였다. 2) PTH에 대한 골아세포의 C-AMP반응으로 증가되었지만 IGF-Ⅰ과 Ⅱ의 투여시 농도변화에 따른 의미있는 변화는 없었다. 3) 본 실험의 조건에서 alkaline phosphatase 활성도는 증가되지 않았다. 이상의 결과로 MC₃T₃-E₁ 골아세포에 IGF-Ⅰ과 Ⅱ는 세포의 증식을 자극하여 PTH는 C-AMP생성을 촉진하는 효과가 있었다. The effect of insulin-like growth factor (IGF) Ⅰ and Ⅱ on cloned MC₃T₃-E₁ cells that had osteoblastic activity was examined by [³H] thymidine incorporation into DNA, cyclic AMP responsiveness to parathyroid hormone (PTH), and alkaline phosphatase activity. IGF Ⅰ and Ⅱ stimulated the growth and proliferation of osteoblastic cells at 20ng/㎖ and 50ng/㎖, respectively. We next examined the effect of IGF-Ⅰ and Ⅱ on the expression of osteoblastic activity. Adenylate cyclase response of PTH to IGF-Ⅰ and Ⅱ-treated cells showed maximal stimulation at 10 and 50㎚PTH, respectively, but IGF Ⅰ and Ⅱ induced limited activity of osteoblastic function. In conclusion, IGF-Ⅰ and Ⅱ were potent stimulators to the growth of osteoblastic cells but did not have an immediate effect on expression of osteoblastic function in this experiment.

Major cardiovascular complications of diabetes are coronary atherosclerosis, diabetic dilated cardiomyopathy, autonomic neuropathy and those are major causes of morbidity and mortality in diabetic patients. Gated blood pool heart scan is noninvasive and useful method for evaluation of functional status of heart in diabetics. We evaluated 52 patients with diabetes and divided 3 groups. Group 1 were 11 patients without proteinuria or with proteinuria less than 550mng during 24 hours. Group 2 were 9 patients with proteinuria more than 550mg during 24 hours and group 3 were 32 patients with endstage renal diasese due to diabetes. We performed 99mTc-HSA cardiac gated blood pool scan and used left ventricular ejection fraction(LVEF), peak ejection rate(PEF) to indices of LV systolic function and peak filling rate(PER) to index of LV diastolic function. The results were follows : 1) LVEF, PER were significantly lower in diabetics with ESRD than diabetics without ESRD, but there were no significant difference between normal controls and diabetics without ESRD 2) PFR was significantly lower in diabetics than normal controls, but there were no significant differences in diabetics with or without nephropathy. 3) There were negative correlation between PER, PFR and duration of diabetes. On the basis of results, PFR is a LV functional index of GBPS which can disclose early change of LV dysfunction in patients with diabetes.

Chronic antipsychotic treatment can induce tardive dyskinesia and supersensitivity psychosis, and these may be explained by supersensitivity phenomena of the dopamine receptor in the brain. This study was conducted to compare the clinical characteristics between tardive dyskinesia and supersensitivity psychosis in schizophrenia. The subjects of the study were composed of 8 schizophrenics with tardive dyskinesia(TD ), 10 schizophrenics with supersensitivity psychosis(SP), and 5 schizophrenics with both syndromes(TD with SP). They all had been treated with antipsychotics. We compared the difference in general and antipsychoti-related characteristics among the three groups. The results are as follows : 1) In the comparison of general characteristics ; There was a significant difference in the number of hospitalizations among the three groups. The number of hospitalizations was most frequent in SP group, and this was followed by TD with SP group(P<0.05). There was also a significant difference in the length of hospitalization : the longest in SP group and the shortest in TD group. Among the schizophrenic subtypes by Andreason-0lsen's criteria, the number of positive schizophrenics were significantly greater in SP and TD with SP group than in TD group(P<O.05) . 2) In the comparison of antipsychotic-related characteristics : There was a significant difference in the current antipsychotic dose among the three groups. The current antipsychotic dose was highest in SP group and this was followed by TD with SP group(P<0.05). The therapeutic response to antipsychotics was significantly better in SP group than in TD group, and the serum prolactin level was significantly higher in SP group than in TD group, and the serum prolactin level was significantly higher in SP group than in TD group(P<0.05; respectively) 3) Regardless TD, if SP was present, the serum prolactin level was significantly correlated to the current antipsychotic dose(P<0.05). 4) But, there was no significant difference in mean age, age of onset, duration, schizophrenic subtype by DSM-Ⅲ criteria, duration of antipsychotic treatment, prognosis, and antipsychotic potency among the three group.

1999년 8월3일~8월4일간 태풍 올가 도래시 건풍에 의한 생육중기 엽신 피해의 품종간 차이와 출수기 이삭 갈변에 따른 수량 및 품질에 미치는 영향을 조사하여 다음과 같은 결과를 얻었다. 1. 잎의 증산량 및 수분저하속도가 클수록, 잎이 길이가 길고 폭이 넓을수록 엽신의 피해정도가 컸다. 2. 이삭의 피해 정도가 증가될수록 임실 및 등숙비율은 현저히 낮아지는 경향이며, 쌀 수량은 무피해 대비 피해 3~5는 14~16%, 피해 7은 28%, 피해 9는 48% 감수하였다. 3. 이삭의 피해 정도별 백미 완전미 비율은 피해 정도가 클수록 감소를 보였으며 피해 0~3에서 63~65%, 피해 5~9에서 42~58%의 분포를 보였다. 4. 이삭의 피해정도가 증가할수록 백도 및 색도치가 낮아지며, 단백질 함량은 증가하고 식미치는 저하하는 경향을 보였다. This study was carried out to characterize the influence of dry wind by typhoon "Olga" during Aug. 3~Aug. 4, 1999 on the rice plant(Oryza sativa L.). For the purpose, the affection of the dry wind during the mid-growing stage and heading stage on the leaf damage, yield and rice quality were investigated. The extent of the leaf damage increased with the increase of leaf size and transpiration rate, and also with the decrease of moisture content in the leaves. The percentage of fertile grain decreased in proportion to the increase of the extent of the panicle damage. Compared with none-damaged rice plants in the panicle, the milled rice yield decreased by 14~16% in the degree 3~5 of the panicle damage, and 28~48% in the degree 7~9. The percentage of head rice was the same in the both milled and brown rice in the degree 0~3 of the panicle damage. Above the degree 5, however, it decreased with the increase of the panicle damage. The whiteness and lightness decreased in proportion to the increase of the degree in the unhulled, brown and milled rice. And, there was a tendency that the protein content in the milled rice increased but eating quality decreased with the increase of the panicle damage.
