This study was carried out for the purpose of knowing the effect from anti-allergic action of B cells and the IC-2 mast cells the extraction from Xanthii Fructus(EXF). In order to know the effect of the cytotoxicity from extraction of Xanthii Fructus, we had to examine the safe density of EXF on lung fibroblast cells of the mouse (mLPCs). We also attempted to resolve the relationship cytotoxicity. The effect was on the organization of cytokine gene expression from the increas and divorce of the B cells and allergic acting by EXF, we found it necessary to examine the IC-2 cells and B cells. We examined the histamine release of IC-2 cells by ELISA method, we also examined the effect of EXF on the increase and divorce of the B cells by ^3H-thymidine uptake method. We then analyzed the release of IL-4, IgE and nitric oxide (NO). The results are as follows : 1. EXF did not show cytotoxicity against mLFCs. 2. According to the inspection on the effect on IC-2 cells gene expression by EXF, we found out the following results: EXF reduced IL-4, IL-6, GM-CSF, TNF-α gene expression and histamine release of IC-2 cells. The EXF inhibited signs of inflammation IC-2 cells.

In order to investigate the hematopoietic effects of Pseudostellariae Radix various experiment about hematopoiesis were studied. The results were obtained as follows: 1. In the proliferous effect of bone marrow cells, water extracts of Pseudostellariae Radix played an important role on the proliferating bone marrow cells compared with control group. 2. The water extracts of Pseudostellariae Radix activated the bone marrow cells. 3. The water extracts of Pseudostellariae Radix promoted the proliferation of the bone marrow cells into cluster, BFU-E, CFU-GEMM. 4. In the bone marrow cells treated with CTX, the water extracts of Pseudostellariae Radix promoted the SCF, EPO, IL-4, IL-6 gene expression, but gene expression of its receptors, c-kit, EPO-R, TPO, c-mpl, EKLF, GATA-1 were not promoted significantly. According to the above results, water extracts of Pseudostellariae Radix promoted not only the differentiation of the bone marrow cells into CFU-GEMM which mother cell of erythrocytes, thrombocytes, monocytes and macrophages, but also the differentiation of the bone marrow cells into BFU-E. On the other hand, in the gene expression that have a lot of hematopoietic effects in the early differentiation of haematopoietic stem cells by promoting the gene expression of SCF, EPO, IL-4, IL-6 and so forth. Above results also demonstrates that the water extracts of Pseudostellariae Radix have somewhat meaningful effects in hematogenesis but not sufficient to explain its mechanisms about hematogenesis, therefore further deep studies should be accomplished about its mechanisms.

Seo-Young Lee 한국무역연구원 2019 무역연구 Vol.15 No.4

Purpose - This paper examines the effectiveness of the duty drawback system in the promotion of export in Korea In particular, this study analyzes and compares the effects of individual drawback and simplified fixed drawback types of duty drawback. Design/methodology/approach - The empirical analysis examined how the simplified fixed drawback and the individual drawback of duty drawback affected export supply. To analyze the independent variable, an export supply equation was formed using variables such as values of duty drawback, export relative price, and domestic demand pressure. The study began with tests of the stationarity of time series data. The unit root tests showed that all concerned variables were non-stationary. Accordingly, the result of cointegration test showed that the tested variables are not cointegrated. Findings - The empirical evidence using the first differenced data shows that the provision of individual drawback and simplified fixed drawback types of duty drawback by the government does have a significant effect on increasing the export supply of Korea. In other words, the empirical evidence shows that the duty drawback scheme of Korea contributes to export promotion. Research implications or Originality - The analysis of the effect of export promotion by type of drawback is a research topic that has not been attempted in previous studies. The results of this study will provide sufficient basis for the policy implications in the operation of the duty drawback system. Therefore, this study can provide important policy implications in terms of export promotion and efficient allocation of resources, as well as improving the system of duty drawback system, which is an exceptional export subsidy system that can be legally operated under the WTO system.

Actinomycosis is a chronic suppurative infection, whitch infiltrates mucosa-associated tissues. Thoracic, pelvic and cervicofacial infections of actinomyces are not uncommon, but endobronchial actinomycosis is rarely reported. We report a case of a 29 year old man who presented with a recurrent pneumonia and chronic cough. Fiberoptic bronchoscopy revealed occlusion of the right. lower medio-basal segment bronchus with exophytic endobronchial mass. The diagnosis was confirmed histologically by demonstration of sulfur granules in the bronchoscopic biopsy of the mass. Intravenous administration of amoxacillin and clindamycin followed by oral amoxacillin and clindamycin therapy resulted in complete recovery.

이영호,심주철,이상경,서영수,김용관,김규수,김영훈 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.3

연구목적 : 본 교실에서 정신분열병 환자 가족을 대상으로 시행 중인 장기 정신교육적 가족치료모형을 소개하고, 이모형이 가족의 대처방식과 우울증상, 환자가 자각하는 가족의 정서적 지지와 우울증상, 재입원율 및 사회재활상태에 미치는 영향을 평가하였다. 방 법 : 연구대상은 DSM-IV 진단기준에 의해 정신분열병으로 진단받고 외래 통원치료를 받고 있는 환자와 그 보호자였다. 교육군은 전체 19회 교육 중 최소 ⅔이상 참여한 11명의 환자와 가족이었고 비교육군은 부산소재의 종합병원에서 가족교육을 받지 않고 통원치료만을 받았던 11명의 환자와 가족이었다. 정신교육적 가족치료 모형의 효과는 가족의 대처방식과 우울증상, 환자가 자각하는 가족의 정서적 지지와 우울증상, 재입원율, 사호재활 실태로 나누어 평가했다. 평가도구는 The Ways of Coping Checklist의 국내번안용, Family Emotional Support Questionnaire for Transaction. Beck Depression Inventory를 이용했다. 재입원율 및 사회재활 실태에 대한 평가는 환자 및 가족과의 면담을 통해 조사했다. 결 과 : 본 연구의 정신교육적 가족치료 모형 실시 후 가족의 대처방식 중 적극적 대처는 교육군운 의미있게 증가한 반면 비교육군에서는 변화가 없었다. 소극적 대처 교육군은 의미있게 감소했으나 비교육군에서는 변화가 없었다. 가족치료모형 실시 전 가족들은 양군 모두 심한 우울증상을 갖고 있었다. 가족치료모형 실시 후 가족의 우울증상은 교육군에서 감소, 비교육군은 증가를 보였으나 통계적 유의성은 없었다. 환자가 지각하는 가족의 정서적 지지 평가척도점수는 교육군은 의미있는 증가를 보였으나 비교육군에서는 변화가 없었다. 환자의 우울증상의 교육군에서는 현저한 감소를 보인 반면 비교육군은 상반되게 증가했다. 가족의 적극적 대처가 환자가 자각하는 정서적 지지의 증가 및 우울증상 감소와 의미있는 상관관계를 나타냈다. 또한 교육군의 환자들이 비교육군의 환자들보다 장기가족교육 종료시점과 9개월 경과 후의 추적 평가에서 재입원율이 현저히 낮았고, 사회재활상태도 좋았다. 결 론 : 본 연구에서 실시된 장기 가족교육모형은 가족의 대처방식을 향상시키고, 우울증상의 감소를 가져오며, 환자가 자각하는 가족의 정서적 지지 향상 및 우울증상의 호전을 가져오고, 재입원율의 저하 및 사회재활의 향상을 보이는 것으로 나타났다. Objectives : This study was performed to introduce a psychoeducational family therapy model for the families of schizophrenic patient and to investigate the effect of this model on the changes in coping style and depressive symptoms of the family members, and in perception of emotional support by families and depressive symptoms of patients. Methods : Subjects were schizophrenic out-patients, who fufilled DSM-IV diagnostic criteria, and their families. The members of "education group" were 11 families and patients who participated in more than two thirds of 19 sessions of the program. The members of "non-education group" were 11 families and patients who had no experience of family education and were treated in a general hospital in Pusan. Clinical ratings were performed using by The Ways of Coping Checklist, Family Emotional Support Questionnaire for Transactions, and Beck Depression Inventory. Results : Coping style was changed positively, in education group but not in non-education group. The depressive symptoms of families were decreased in educated group and increased in non-educated group, although there were no statistical significance. In education group, patients felt much better emotional support by their families than patients in non-education group did. At the same time, their depressive symptoms were significantly reduced. The patients from education group were on more successful rehabilitation than those from non-education group were. Conclusion : Our results suggest that this psychoeducational family therapy model would be helpful to induce the positive changes in coping styles and reduce the depressive symptoms of family members, and it could also induce the reduction of depressive symptoms of schizophrenic patients and help their rehabilitation.

Background/Aims: The recently published Oxford classification of IgA nephropathy (IgAN) proposed a split system for histological grading, based on prognostic pathological features. This new classification system must be validated in a variety of cohorts. We investigated whether these pathological features were applicable to an adult Korean population. Methods: In total, 69 adult Korean patients with IgAN were analyzed using the Oxford classification system at Soonchunhyang University Hospital, Seoul, Korea. All cases were categorized according to Lee`s classification. Renal biopsies from all patients were scored by a pathologist who was blinded to the clinical data for pathological variables. Inclusion criteria were age greater than 18 years and at least 36 months of follow-up. We excluded cases with secondary IgAN, diabetic nephropathy combined other glomerulopathies, less than 36 months of follow-up, and those that progressed rapidly. Results: The median age of the patients was 34 years (range, 27 to 45). Mean arterial blood pressure was 97 ± 10 mmHg at the time of biopsy. The median follow-up period was 85 months (range, 60 to 114). Kaplan-Meier analysis showed significant prognostic predictions for M, E, and T lesions. A Cox proportional hazard regression analysis also revealed prognostic predictions for E and T lesions. Conclusions: Using the Oxford classification in IgAN, E, and T lesions predicted renal outcome in Korean adults after taking clinical variables into account.

Disposal of a homicide victim by dismemberment is rare, but individual cases are on record in most major medicolegal departments. Recognition of postmortem mutilation may be of importance in the interpretation of certain murders committed by sexual perverts and other mentally deranged individuals and sometimes performed for the sole reason of easier disposal of the body. Postmortem dismemberment is usually readily recognizable as such; The edges of the injuries are dry and lack evidence of bleeding. The joints may be disarticulated without fracture, or the use of an axe or saw may be evident from examination of bones. Parallel horizontal or oblique furrows in the bone surface are caused by skipping of the saw prior to establishing depth. Such patterns on the bone may assist in identifying the particular saw involved. So we report 25 dismembered corpses that autopsied in National Institute of Scientific Investigation. This paper can help in attempting to establish not only the first criminal investigation steps but also the medicolegal approach methods in unidentified and dismembered deaths.
