This observation was aimed to evaluate the clinical manifestations and clinical incidence of $Beh{\varsigma}et's$ Disease. It was records of patients seen in the period between January 1992 and December 1998 at the Department of Dermatology, Oriental Medical Hospital, Kyung Hee University. $Beh{\varsigma}et's$ Disease is a chronic, systemic disease which manifests itself as recurrent, multiple lesions in many organs, including the skin. The clinical features of $Beh{\varsigma}et's$ Disease are important as there is no reliable method of laboratory diagnosis. The results were summarized as follows; 1. The total number of patients were 34, including $42\%$ male and $52\%# female. 2. The pick incidence of age group was 30 to 39($44\%$). 3. The most frequent duration was from 2 years to 5 years($41\%$). 4. According to Diagnostic Criteria of the $Beh{\varsigma}et's$ Disease Research committee of Japan, there were $41\%\;of\;Incomplete\;type,\;29\%\;of\;Suspected,\;24\%\;of\;Complete,\;6\%$ of Passible. 5. The most common major symtom is a oral u1cer($91\%$), and there were erythema nodosum like lesion($79\%$), genital ulcer($56\%$), problem of the eyes($38\%$). 6. The most common minor symtom was arthritis($32\%$). 7. The first main symtom were oral ulcer($50\%$), erythema nodosum like lesion($26\%$), problem of the eyes($18\%$). 8. There were 2 cases of Intestinal $Beh{\varsigma}et's$ Disease and 5 cases of uveitis. 9. The most frequently treated prescription was Eunhwasagantang which occupied 79 of all, Gamisopunghwalhultang($44\%$) a.nd Gamipadoksan($41\%$), Gamiguakjungsan($24\%$) in that order of frequency.

Beh$\c{c}$et's disease has rarely been reported in association with malignant diseases. In most cases the autoimmune nature of the disease itself or immunosuppressive drug use has been blamed for malignant transformation. Solid tumors in addition to lymphoid and hematological malignancies are also seen during the course of Beh$\c{c}$et's disease. We present here a case of colon cancer in a 40-year-old man with Beh$\c{c}$et's disease. A near total colectomy was performed and postoperative chemotherapy and radiotherapy was administered to treat visceral peritoneal invasion. Recurrent evidence was not found. We present the clinical details of this rare case of colon cancer with Beh$\c{c}$et's disease.

To elucidate a potential contribution of endotheline-1[ET-1] to the genesis of pulmonary hypertension and postoperative pulmonary hypertensive crisis in the patients with heart disease, we measured plasma levels of the ET-1 during perioperative period of open heart surgery. In addition, we examined changes of ET-1 during perioperative period and correlations between ET-1 levels and hemodynamic variables. 12 patients including 5 acquired heart disease and 7 congenital heart disease patients were selected randomly as a study group, Group A and B, respectively. 6 patients proved not having heart or hemodynamic problem were selected as a control, Group C. 110 blood samples from pulmonary artery[ET-P] and radial artery[ET-S] were taken and assayed by Sep-pak extraction and RIA. ET-1 levels of Group A were ET-P, 3.94$\pm$5.31pg /ml, ET-S, 3.10$\pm$2.90pg/ml[p>0.05], Group B were ET-P, 1.63$\pm$0.62pg/ml, ET-S, 1.99$\pm$2.45pg/ml[p>0.05], Group C were ET-P, 1.97$\pm$2.02pg/ml, ET-S, 1.72$\pm$0.77pg/ml[p>0.05]. There were no statistically significant differences of ET-1 levels among the Group A, B, C[p>0.05]. There was no correlation between pulmonary artery pressure[PAP] and ET-1 level[p>0.05], and ET-1 levels were not increased even in the cases of pulmonary hypertensive criwis or low cardiac output syndrome, whereas significant correlation between ET-S and pulmonary vascular res-istance[Rp] [r=0.36, p<0.05], and negative correlation between ET-S and OS saturation of pulmonary artery[OS-P][r= -0.49, p<0.01] were identified. Another significant finding was peak increase of ET-1 levels in the postoperative period 1 hour[p<0.05] and then gra-dualy decrease through the postoperative period. In conclusion, ET-1 has no correlation with PAP, whereas correlation with Rp, and inverse correlation with OS-P. It is suggested that ET-1 is neither the direct causative substance of pulmonary hypertension nor pulmonary vasospasm but there must be increased production of ET-1 in chronic pulmonary hypertensive state. Counter-regulatory mechanism to ET-1 is speculated during the pulmonary vasospasm.

Essential tremor(ET) is the most common movement disorder however there has been little agreement in the neurologic literature regarding diagnostic criteria for ET. Familial ET is an autosomal dominant disorder presenting as an isolated postural tremor. The main feature of ET is postural tremor of the arms with later involvement of the head, voice, or legs. In previous studies, it was reported that ET susceptibility was inherited in an autosomal dominant inheritance. As with previous results, it would suggest that ET might be associated with defect of mitochondrial or nuclear DNA. Recent studies are focusing molecular genetic detection of movement disorders, such as essential tremor and restless legs syndrome. Parkinson's disease(PD) is a neurodegenerative disease involving mainly the loss of dopaminergic neurons in substantia nigra by several factors. The cause of dopaminergic cell death is unknown. Recently, it has been suggested that Parkinson's disease many result from mitochondrial dysfunction. The authors have analysed mitochondrial DNA(mtDNA) from the blood cell of PD and ET patients via long and accurate polymerase chain reaction(LA PCR). Blood samples were collected from 9 PD and 9 ET patients. Total DNA was extracted twice with phenol followed by chloroform : isoamylalcohol. For the analysis of mtDNA, LA PCR was performed by mitochondrial specific primers. With LA PCR, 1/3 16s rRNA~1/3 ATPase 6/8 and COI~3/4 ND5 regions were observed in different patterns. But, in the COI~1/3 ATPase 6/8 region, the data of PCR were observed in same pattern. This study supports the data that ET and PD are genentic disorders with deficiency of mitochondrial DNA multicomplexes.

Discrimination of Parkinson's disease (PD) from Essential tremor (ET) is often misdiagnosed in clinical practice. Since tremor is time-varying signal, and dominant and harmonic frequencies are shown in tremor only with moderate or severe symptom, there are some limitations to use frequency related features. Moreover, patients with PD or ET can suffer from both resting tremor and postural tremor. In this study, 28 patients with PD and 17 patients with ET were enrolled. Tremor was measured with accelerations on the more affected hand during resting and postural conditions. The ratio of root mean square (RMS) of resting tremor to RMS of postural tremor, the mean coefficients of autocorrelation function (ACF), and the mean of differences of two adjacent coefficients of ACF at resting and postural were calculated and compared between PD and ET. The performance showed 98% accuracy with support vector machine and leave-one-out cross validation. In addition, the method accurately differentiated the patients with tremor-dominant PD from patients with ET, with 100% accuracy. Therefore, the developed algorithm can assist clinicians in diagnosing and categorizing patients with tremor, especially, patients with mild symptom or the early stage of a disease, for proper treatment.

시상은 체감각 정보를 처리하는데 있어서 매우 중요한 역할을 하는 부위이다. 본 연구는 운동장애 환자의 시상에서 뉴론의 활동 특성을 알아보기 위해 수행되었다. 그 결과 체감각으로서의 운동자극에 반응하는 뉴론이 essential tremor (ET) 환자의 nucleus ventralis intermedius (VIM)에서 발견되었다. ET 환자 뉴론의 평균 활동율(firing rate)은 Parkinson's disease (PD) 환자 보다 높았다. 또한 ET 환자의 VIM에서 운동자극에 반응하는 뉴론의 평균 활동율은 PD 환자 보다 높았다. 하지만 촉각자극(touch)에 반응하는 nucleus ventralis caudalis (VC) 뉴론의 활동율은 ET와 PD 집단간에 차가 없었다. Bursting activity를 나타내는 뉴론은 nucleus ventralis oralis anterior (VOP)에서 ET집단이 PD 집단보다 적었다. tremor cell은 VIM에서 PD 보다 ET집단이 더 적었다. 이러한 결과는 체감각 자극에 반응하는 시상 뉴론의 특성이 운동장애의 유형에 따라 서로 다르다는 것을 시사한다.

Antimicrobial activity of Caesalpina sappan L. extract (CS extract) against animal husbandry disease-related bacteria was studied. The CS extracts showed a significant antimicrobial activity against Gram(+) bacteria and this antimicrobial activity was most significant against Staphylococcus epidermidis. Minimum inhibitory concentrations (MIC) of CS was in the range of 0.8∼16 mg/ml and 0.8∼10 mg/ml, in the case of MeOH extracts and EtOH extracts, respectively. In addition, the antimicrobial activity of each solvent fraction was most significant with EtOAc layer. The antimicrobial activities of CS extracts against most microbial strains were stable by either heat treatment or acid treatment, whereas those against S. aureus and Sal. typhimurium were reduced by acid treatment. The inhibitory effect of CS extracts on microbial cell growth was further examined by the addition of 0, 100, 300, and 500 ppm of CS extracts into growth medium. The growth of gram(+) bacteria, S. aureus and S. epidermidis, was inhibited for 72 hours in all ranges of CS extracts added, but the growth of gram(-) bacteria was only inhibited when at least 100 ppm of CS extracts were added. Taken together, the antimicrobial activities of CS extracts were more effective against gram(+) bacteria compared to those against gram(-) bacteria.

Six fractions of Salvia miltiorrhiza were tested for their chemopreventive potentials using biochemical markers of carcinogenesis such as quinone reductase (QR), glutathione S-transferase (GST) and glutathione (GSH). Seventy percentage of EtOH extract was potent inducer of QR activity in Hepa1c1c7 murine hepatoma cells. GST activity was increased about 1.4-fold with EtOAc extract at concentration of 50 ${\mu}g/ml$. GSH levels were significantly increased with $H_2O$ extract, 70% EtOH extract and water extract at concentration of 50 ${\mu}g/ml$ (p<0.005). From these results, 70% EtOH extract (250 mg/kg) was intragastrically administered to ICR mice for 14 days. QR, GST and GSH levels were significantly increased with the 70% EtOH treatment. These studies suggest that the 70% EtOH extract of S. miltiorrhiza could be considered as a potential agent for cancer chemoprevention.

Objectives: The prevalence of Parkinson's disease is on an upward trend along with an increase in the aging population but there is no available treatment that halts the progression of neurodegeneration. This study reports a numerical analysis on Donguibogam and suggests novel herbal drugs, which have never been researched before but found to be deemed effective in this study. Methods: Referring to 71 Korean medicine symptom terms that represent the symptoms of Parkinson's disease, 4170 prescriptions described in Donguibogam were classified into two groups based on whether their main effects were effective for Parkinson's disease or not. Comparing the two groups, the chi-square test was performed to select statistically significant herbs, while the t-test, Wilcoxon test, and descriptive statistics were performed to determine the appropriate dose. Results: One hundred and twenty-seven prescriptions effective for Parkinson's disease were identified. The chi-square test determined 17 herbs that are effective for symptomatic treatment. Among the medicinal herbs, the authors suggest Osterici seu Notopterygii Radix et Rhizoma, Ephedrae Herba, Aconiti Tuber, Myrrha, Sinomeni Caulis et Rhizoma, and Aconiti Kusnezoffii Tuber as herbal candidates that have never been studied for Parkinson's disease. Through the statistical tests, it was judged that the mean value of the dose of the entire prescription was the appropriate dose for each herb. Conclusions: Seventeen herbs were selected for Parkinson's disease and the appropriate daily dose were calculated. Furthermore, this study presented a new process that applies a statistical method to traditional medical literature and preselecting herbs deemed effective for specific diseases.
