Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

Responses to chemotherapy correlate with the increased dose of chemotherapeutic agents in some cancers, e.g. breast cancer, Ewing's sarcoma, Hodgkin's disease(HD) and non-Hodgkin's lymphoma(NHL), then for the improvement of the chemotherapy responsiveness, high-dose chemotherapy(HDCT) was proposed. But, it's application was limited due to complications, especially bone marrow suppression. HDCT and succeeding autologous peripheral blood stem cell transplantation(APBSCT) was introduced to overcome this problem. This study was designed to determine the clinical pictures including clinical parameters and the responsiveness of HDCT followed by APBSCT in Hanyang University Hospital. Ten patients were enrolled. They were 8 adults (3 breast cancers, 3 multiple myelomas, 1 HD, 1 NHL) and 2 children (1 acute myelogenous leukemia (AML), 1 neuroblastoma). Mobilization chemocherapy(MCT) followed by Granulocyte Colony Stimulating Factor(G-CSF) was administered to mobilize stem cells from bone marrow to peripheral blood. The stem cells were collected by using CS-3000 and cryopreserved at -196℃ with programmed controlled rate freezer as the mixture with 10% dimethyl sulfoxide(DMSO). HDCT was administered and cryopreserved peripheral stem cells were infused on day 0 as planned. Patients' mean age was 41 years old. After induction chemotherapy three patients achieved complete response and 5 partial response. The median time for bone marrow recovery after MCT was 11.5 days for neutrophil(〉500/㎣) and 4.8 days for platelet(〉20,000/㎣). There were three cases of neutropenic fever and one case of gingivitis. After HDCT with APBSCT, one patient was converted partial response to complete response, and one patient achieved complete response after HDCT without induction chemotherapy. The median time for bone marrow recovery was 12.7 days for neutrophil(〉500/㎣) and 14.7 days for platelet(〉20,000/㎣). Eight patients developed neutropenic fever and required systemic antibiotics. Transfusion was required 1.6 pints for packed red cell and 23.4 pints for platelet concentrates. Toxicity consisted mainly of vomiting, diarrhea, and mucositis which were mild. HDCT with APBSCT can be performed safely with minimal complications. For the evaluation of the exact role of HDCT with APBSCT in malignant diseases, further studies are required as a large scale of patients and lung-term follow up.

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.

The purpose of this study was to evaluate the response in aspect of attachment and growth rate of osteablasts and human gingival fibroblasts to the commercially pure titanium(CP titanium) and titanium alloy(Ti-6A1-4V) that are used widely as implant materials, and to obtain the basic information to ideal implant materials. In this study, commercially pure titanium in first test group, titanium alloy(Ti-6A1-4V) in second test group, cobalt-chromemolybdenum alloy(Co-Cr-Mo alloy) in positive control group, and tissue culture polystyrene plate in negative control group were used. The results of this study were as follows. 1. Bone marrow cells cultured on CP titanium and Ti-6A1-4V showed significantly greater attachment and growth rate(p<0.05) compared to Co-Cr-Mo alloy in each time. 2. There were no significant differences(p>0.05) in attachment and growth rate of bone marrow cells cultured on GP titanium and Ti-6A1-4V or tissue culture plate. 3."Most bone marrow cells cultured on CP titanium, Ti-6A1-4V and tissue culture plate were attached well to each substratum in first 2days, and then, grew at higher growth rate. On the other hand, some cells cultured on Co-Cr-Mo alloy failed to attach in first 2 days, and then, attached cells grew at lower growth rate than other groups. 4. Attachment and growth rates of gingival fibroblasts cultured on CP titanium and Ti-6A1-4V showed no significant differences(p>0.05) compared to Co-Cr-Mo alloy in 2 days, but significantly greater increase(p<0.05) in 5 and 9 days. 5. There were no significantly differences(p>0.05) between growth rates on gingival fibroblasts cultured on CP titanium, Ti-6A1-4V and tissue culture plate in 2 and 5 days, but a significant lower growth rate(p<0.05) on CP titanium and Ti-6A.1-4V versus tissue culture plate. 6. Some gingival fibroblasts cultured on all specimen groups failed to attach, but attached cells grew well especially on CP titanium, Ti-6A1-4V and tissue culture plate. 7. There were no significant differences(p>0.05) between growth rates of both bone marrow cells and gingival fibroblasts cultured on CP titanium and Ti-6A1-4V. As a result of this study, both commercially pure titanium and Ti-6AI-4V showed excellent biocompatibility and there was no significant difference in the cellular response to the both metals. Bone marrow cells cultured on each substratum showed significantly greater growth rate and responded sensitively to cytotoxic effects of metal surfaces compared to gingival fibroblasts. Considering cell response to the substrate, it was likely that the composition itself of titanium metals have no significant effects on the biocompatibility. Further study need to be done to evaluate the influence of surface characteristics on cellular responses.

This study was purposed to investigate the effect of yukmijihwangtang on rat blood components and organ histopathologic changes in the different environments of hyperbaric ambient air. The pharmacological effects of yukmijiwhangtang in oriental medicine have been reported to improve general condition and treat mental and physical weakness due to overload. 84 Male Sparague-Dawely rats, 200-250 g weight, were housed two per cage, fed Standard Rodent Diet with water ad libitum. The animals were assigned to 3 main groups for the blood components and gas analysis : normobaric control group (NC ; N=4), hyperbaric control group (HC ; N=8), hyperbaric medication group (HM ; N=8). HC and HM group were devided into 2 subgroups and kept on different situation of the hyperbaric ambient air (2ATA or 3ATA) for 2 hrs. HM group was administered 10cc extract of boiled yukmijiwhangtang before exposure. For histopathological analysis, hyperbaric groups(HC and HM : N=80) was further devided into 2 subgroups according to atmosphere absolute and exposure period : 2ATA (acute, 1, 2, 3, 4 wks), 3ATA (acute, 1, 2, 3, 4 wks). There were 20 groups in total, with 4 animals in each group. Experimental rats of HM group were administered 10cc extract of boiled yukmijiwhangtang 2 times per day and kept on situation of the hyperbaric ambient air (2ATA and 3ATA) 2 hrs per day for four weeks. In order to record the possible effects of yukmijiwhangtang in hyperbaric condition on the blood components, the rats were killed by decapitation directly after the hyperbaric exposure for 2 hrs. But the administered rats were killed on the morning following the last hyperbaric exposure during 4 wks. The samples were taken 2 hrs, 1, 2, 3, 4 wks after the begining of this study. Blood was collected from posterior abdominal vena cava immediately after decapitation. Organs for histopathological assays in hyperbaric groups (HC and HM) were also removed 2 hrs, 1, 2, 3, 4 wks and fixed at 10% formalin solution. The whole blood of 1㎖ was used for the analysis of pH, PO₂, PCO₂, HCO₃, BE, O₂CT, O₂SAT level by Blood Gas Autoanalyzer (Coning 175, U.S.A). And The rest whole blood of 1㎖ was utilized for the measurement of WBC (white blood cell), RBC (red blood cell), Hb (hemoglobin), Hct (hematocrit), MCV (mean corpuscular volume), MCH (mean corpuscular hemoglobin) level by Microcell Counter (Model; CC-170-TDA Co., Japan). Hematological and blood gas analysis and organ histopathological changes after exposure to hyperbaric ambient air were as follow; (1) Hematological parameters were lower in the hyperbaric medication group than all the control groups without WBC, MCV (2ATA) and MCV, MCH (3ATA). But a statistical significance among the groups was not shown. (2) The hyperbaric medication group was lower than another control groups on all parameters of blood gas analysis after 2 hours exposure to hyperbaric ambient air (2ATA and 3ATA) without O₂SAT. But a statistical significance among the groups was not shown. (3) On observing the histopathological system of the lung with microscope, the congestion, edema and hemorrhage on the alveolar sacs and alveolar wall damage in the hyperbaric control group were heavier than in the hyperbaric medication group.

오승준,김영설,박철영,김덕윤,김성운,양인명,김진우,최영길,팽정령,정경천 대한비만학회 2000 The Korean journal of obesity Vol.9 No.2

연구배경 : 혈전현상을 특징으로 하는 질환에서는 Plasminogen activator inhibitor-1 (PAI-1) 이 높은 활성도를 보이는데, PAI-1 치는 당뇨병, 심근경색증, 비만 등에서 높다고 밝혀진 바 있다. 또한 당뇨병 환자들의 합병증의 주요한 병인은 죽상경화증으로 혈전현상이 특징인 질환에서 증가하는 PAI-1이 당뇨병 환자에서 높다. 목적 : 정상인에서의 PAI-1 유전자 촉진자의 유전자형의 분포 및 혈액농도를 관찰하고, 당뇨병 및 뇌혈관 질환 환자군에서의 PAI-1 유전자 촉진자 유전자형의 분포 및 혈액농도를 측정하여 정상인과 차이점을 알아본다. 당뇨병 환자군에서의 혈장 PAI-1 치와 인슐린 저항성, 전구 인슐린 등과의 상관관계를 살펴보고, 인슐린저항성과 대혈관질환의 지표로 사용될 수 있는지 알아보았다. 방법 : 대상으로는 정상인 76명, 제2형 당뇨병 환자 56명, 뇌혈관질환이 동반된 제2형 당뇨병 환자 48명, 뇌혈관질환 환자 51명을 선택하여, 환자의 혈액에서 인슐린, 공복시 혈당, 전구인슐린, 중성지방, 총콜레스테롤 및 기타 생화학 검사 및 이학적 검사를 시행하였다. 환자의 DNA를 채취하여 전사개시 -675bp를 포함하는 대립형질 특이 시발체를 사용하여 중합효소 연쇄 반응을 실시하여, 그 유전자형을 판독하였다. 결과 : 정상 대조군 76명 (46.4±11.1세), 2형 당뇨병 환자 56명 (58.3±12.6세), 뇌경색증 환자 51명 (63.1±13.2세) 대상으로 하였다. PAI-1 촉진자 유전자형의 (4G/4G, 4G/5G, 5G/5G)빈도는 정상 대조군이 각각 23.7%, 75.0%, 1.3%, 뇌경색 환자군이 19.6%, 66.7%, 13.7%, 뇌경색이 동반된 당뇨병 환자군이 33.3%, 58.3%, 8.3% 였다. (X2=12.6, p=0.05). 이러한 사실은 서구인에 비해 4G/4G, 5G/5G 동형 유전자형이 낮은 결과였다. 각 군별 혈장 PAI-1 농도는 정상 대조군 13.4, 1.8 ~ 65.2 ng/mL (중앙값 , 범위 ) 2형 당뇨병 환자군 14.4, 2.9 ~ 47.8 ng/mL, 뇌경색 환자군 21.9, 6.2 ~ 154.7 ng/mL , 뇌경색이 동반된 2형 당뇨병 환자군 28.8, 3.2 ~ 139.3 ng/mL 로 차이를 보였다 (p=0.000). 전체 대상에서 PAI-1 촉진자 부위의 유전자형에 따른 PAI-1 활성도와 항원 농도는 차이를 보이지 않았다. 그러나 PAI-1 활성도는 혈중 중성지방, 전구인슐린, 체질량지수와 독립적인 상관관계를 보였다 (p=0.000, p=0.000 and p=0.005). 결론 : 결론적으로 PAI-1 촉진자 부위의 유전자형은 뇌경색증의 지표는 아니며, PAI-1 활성도를 결정짓는 인자는 유전적 요인보다는 혈중 중성지방, 전구 인슐린, 체질량지수와 같은 대사적 요인으로 생각된다. Plasminogen activator inhibitor-1 (PAI-1) is known be related to insulin resistance and several components of the large vascular disease. Notably, the high frequencies of diseases such as coronary heart disease or stroke are related to type 2 diabetes complications. We studied to find out whether the PAI-1 promother genotype could be a marker for cerebral infarction in type 2 patients. Subject patients were; 56 type 2 diabetics (age 58.3±12.6), 51 patients with cerebral infarction (age 63.1±13.2), 48 type 2 diabetics with cerebral infarction (age 64.8±9.3) , and 76 healthy control (age 46.4±11.1). The 4G/5G genotype of PAI-1 promoter was evaluated by polymerase chain reaction and endonuclease digestion. PAI-1 promoter genotype frequency (4G/4G, 4G/5G, 5G/5G) was 23.7%, 75.0% and 1.3% in healthy control, 17.9%, 67.9% and 14.3% in type 2 diabetes patients, 19.6%, 66.7% and 13.7% in cerebral infarction patients, 33.3%, 58.3% and 8.3% in type 2 diabetics with cerebral infarction (X^2=12.6, p=0.05). This finding is lower in frequency of 5G/5G homozygote than that reported in Caucasians. The plasma PAI-1 concentrations according to the disease were 13.4, 1.8 ~ 65.2 ng/mL (median, range) for healthy control, 14.4, 2.9 ~ 47.8 ng/mL for type 2 diabetes, 21.9 6.2 ~ 154.7 ng/mL for cerebral infarction , and 28.8, 3.2 ~ 139.3 ng/mL, for cerebral infarction with type 2 diabetes (p=0.000). In the all subjects, PAI-1 concentration and activity of PAI-1 promoter genotype did not show any significant difference. However, the PAI-1 activity was independently associated with serum triglyceride level, plasma proinsulin and BMI (p=0.000, p=0.000 and p=0.005 respectively). We concluded that PAI-1 genotype is not a marker for the cerebral infarction ; however, the genotype is related to PAI-1 concentration , and therefore it seems to be that metabolic factors such as triglyceride level or plasma proinsulin or BMI are more in relations with determining the PAI-1 concentration than the genotype.

오준,김영찬,김명렬 順天大學校 1999 論文集 Vol.18 No.1

The specific heat of molecular sieves 3A(MS 3A) is determined by fitting method for N₂-MS3A system at room temperature. The specific heat obtained for MS3A was 1035 J/㎏·K. The specific heat is also determined by moment method and compared with that from the fitting method. The specific heat of MS3A obtained from the first order moments is similar to that from the fitting method.
