Background : The area of ginseng cultivation has nearly exhausted in the main ginseng growing area in Korea but virgin fields need for ginseng cultivation due to continuous cropping injury. To count for the decrease of the virgin fields of ginseng cultivation, technical improvement to increase, or maintain the amount of harvest are necessary in ginseng cultivation. The Ginseng Rain-sheltered Shade House is one of the efficient cultivation techniques as reducing the damages caused by natural disaster such as blight, high temperature & humidity, dry, and heavy rain & snow. However a soil description needs to be developed to reduce the period of re-cultivation because ginseng has to be cultivated at the only one ginseng rain-sheltered house without soil or cultivation change. Methods and Results : This study was carried out in the ginseng rain-sheltered house where ginseng had cultivated and harvested one time. Each section of Cultivation of sudan grass+flooding, rice straw+flooding, and flooding was covered with vinyl and then, all areas were solarized through the summer season. The soil temperature was inspected at 5cm, 10cm, 15cm, and 20cm below ground. As a result, the soil temperature of the place with vinyl covered and solarized was approached to 40℃ regularly during the period of high temperature in July and August. After the solarization, the inspection result of Cylindrocarpon destructans spore density checked by Real time PCR was that C. destructans spores were not found at the place where sudan glass+flooding and rice straw+flooding were used. However, the detected number of C. destructans spores in the inspection condition was roughly 9 at the soil samples from the fields which were flooded and solarized, and 33 at those from the repeatedly cultivated fields. The evaluations of aerial part growth by measurements were good in the following order: Sudan grass+flooding, rice straw+flooding, and flooding. Conclusion : The purpose of this study was to reduce the period of ginseng re-cultivation in a ginseng rain-sheltered shade house. The incidence rate of the pathogens distantly decreased by the treatments of sudan glass + flooding, rice straw+flooding, and solarization.

Synovial sarcomas' are rare malignant neoplasms that arise from mesenchymal cells of tendosynovial tissue, accounting for about 7% of adult soft tissue sarcomas, and occur with maximal frequency in the second through fifth decades of life. The incidence of metastasis is high, most often to the lung, regional lymph nodes and bone, despite of radical surgery for primary tumor. The histologic subtypes of synovial sarcoma generally accepted are monophasic, biphasic and poorly undifferenciated types, and all synovial sarcomas have been classified as high grade soft tissue sarcoma due to high metastatic potentials by the American Joint Committee on Cancer. Spontaneous pneumothorax due to primary pulmonary neoplasm is uncommon, and pneumothorax due to pulmonary metastasis is very uncommon condition. The most common primary tumor causing spontaneous pneumothorax is sarcoma, and of these the majority are osteosarcomas. Various mechanisms have been suggested to explain how a spontaneous pneumothorax occurs as a result of pulmonary involvement of malignancy. Bilateral spontaneous pneumothorax from pulmonary metastasis of synovial sarcoma has been reported very rarely in the world literature, and has not yet been reported in Korea. We present here a very rare case of recurrent synovial sarcoma manifested as bilateral spontaneous pneumothorax, who had been treated with surgical resection and radiotherapy for the synovial sarcoma on left popliteal fossa and review the pertinent literatures.

Background/Aims: To investigate if BK virus (BKV)-specific T cell immunity measured by an interferon-γ enzyme-linked immunospot (ELISPOT) assay can predict the outcome of BK virus infection in kidney transplant recipients (KTRs). Methods: We included 68 KTRs with different viremia status (no viremia [n = 17], BK viremia [n = 27], and cleared viremia [n = 24]) and 44 healthy controls (HCs). The BK viremia group was divided into controller (< 3 months) and noncontroller ( > 3 months) according to sustained duration of BKV infection. We compared BKV-ELISPOT results against five BKV peptides (large tumor antigen [LT], St, VP1-3). Results: BKV-ELISPOT results were higher in three KTRs groups with different BKV infection status than the HCs group (p < 0.05). In KTR groups, they were higher in cleared viremia group than no viremia or BK viremia group. Within the BK viremia group, controller group had higher LT-ELISPOT results compared to noncontroller group (p = 0.032). Also, KTRs without BK virus-associated nephropathy (BKVN) had higher LT, St, VP1, and VP2-ELISPOT results than those with BKVN (p < 0.05). Conclusions: BKV-ELISPOT assay may be effective in predicting clinical outcomes of BKV infection in terms of clearance of BK virus and development of BKVN.

N/A Background: Massive hemoptysis is one of the major medical emergency with high risk of mortality. Though the best predictor of mortality associated with hemoptysis appears to be the amount of bleeding within the first 24 hours, catastrophic hemorrhage could be occurred to the patients who were apparently in a stable condition with scanty hemoptysis at the time of admission. We evaluated APACHE III score system to find if it could be a prognostic index that can predict the mortality of the patients with hemoptysis. Methods : We identified all the patients who had admitted with hemoptysis in the Medical Intensive Care Unit of Asan Medical Center between May 25, 1989, and July 31, 1995. A retrospective analysis was done in 66 patients with hemoptysis on APA- CHE III score. Results: The overall mortality rate was 17.4% (12/69). In univariate analysis of possible prognostic factors, independent predictors of mortality were age(P=0.016), amount of hemoptysis(P=0.012), AaDO2 (P=0.017), requirement of transfusion(P=0.036), mechanical ventilatory care(P<0.05) and APACHE III score(P=0.02), In multivariate analysis with sex, age, amount of hemoptysis, AaDO2, requirement of transfusion and APACHE III score, APACHE III score was the only independent predictor of mortality(P=0.015, odd ratio=19.3, 95% confidence interval, 3.4 to 249.7) Conclusion: APACHE IU score may be a clinically significantly important independent predictor of outcome in the patients with hemoptysis. In addition, invasive procedure, such as bronchial artery embolizaticn or operation, could be considered in advance in the patients with more than 30 points of APACHE III.
