This experiment was conducted at the Seoul National University Arboretum at Seodun-dong, Suweon, Kyeonggi-do, Korea (1) to find out methods killing Robinia pseudoacacia L. effectively and (2) to minimize ecological and aesthetic problems. Glycine and 2, 4-D were treated in several concentration following the saw-scratching and cutting of stems on July 22 and 29, 1985. The results were measured on October 17, 1885. The results obtained were as follows: 1. Ecological problems were decreased by these methods. 2. In case of herbicides treatment on section area, aesthetic problems were minimized, and amounts of herbicide consumption were five times as little as in case of spraying plants with herbicides. 3. The death rate amounted to 100% when the ratio of Glycine solution to water was 1:3, so that the concentration, 1:3 was most economical to kill the tree throughly. 4. The death rate amounted to 100% when the ratio of Glycine solution mixed with 2, 4-D to water was 1:4, therefore Glycine solution mixed with 2, 4-D was more effective than pure Glycine solution. Since 2, 4-D solution was less expensive than Glycine solution and only small amounts of 2, 4-D solution was added, it was most economical and effective method that Glycine solution mixed with 2, 4-D was diluted to the concentration, 1:4 and treated on the stem.

The third year's results on effects of surface fire on frest vegetations and soil properties were investigated in Mt.Gwanak, Kyunggi-do successively after the study of the first year's effects in the same place. Organic matters in soil had increased just after fire and whatsome decreased during 1 year after fire, and resulted in percentage that was less than unfired area in the third year after fire. The pH of subsoil was continuously increasing from just after fire till after 1 year, but decreased somewhat in the third year after fire. More exact classification into Increasers, Decreasers, Invaders and Neutral species was possible in the third year's study. According to comparison of similarities, the vegetational structure of the species at fired area has been gradually restoring to original state as time goes by.

The shallow soil depth and severe rock exposures on the hillslopes in the Kwanak aboretum area which resulted from the heavy soil erosion have made very poor growth of forest vegetation. In order to establish the forest vegetation in this area, it is urgent to recover the fertility of soil and the productivity of existing trees. For this reason, fertilization experiment (using the briquet compound fertilizer) was conducted on summer and autumn season in 1983 with the 4 main native species (Pinus densiflora, Pinus rigida, Juniperus rigida, Rhododendron schlippenbachii) growing on these eroded hillslopes. Result in 1985 and 1986 of this experiment represented that the fertilization was effective toward both height and root-collar diameter growth of trees and spring fertilization was, relatively, more effective than autumn fertilization. It also represented that effects of fertilization to P. rigida were more than those to other species. Therefore, besides the engineering methods and afforestation measures for soil erosion control, rapid establishment of vegetation through conservation and recovery of existing trees by fertilization is available measures for the rehabilitation of rockily eroded hillslopes like Mt. Kwanak area.

樹木園 活成豫定地를 對象으로 土壤 水分含量과 植生을 調査하여 앞으로의 樹木園 造成에 필요한 情報를 얻음과 동시에 樹木園 造成에 따른 植生破壞後 原來植生에 關한 情報가 必要할 때 參考하기 爲하여 1985年 6月 12日에 本 調査를 實施하였는데 그 結果는 다음과 같다. 1. 全體的으로 겨이삭(Agrostis clavata var. nukabo)의 優占度가 매우 높았으며 씀바귀(Ixeris dentata)와 흰씀박귀(Ixeris dentata var. albiflora)는 극히 乾燥한 곳을 제외하고는 대부분 優占度가 높았다. 濕한 곳에는 왕비늘사초(Carex maximowiczii), 기장대풀(Isachne globosa) 等이, 극히 乾燥한 곳에서는 잔디(Zoysia japonica)가, 보통 乾燥한 곳에서는 그늘사초(Carex lanceolata), 김의털(Festuca ovina) 等이 優占度가 높았다. 2. 特히 稀貴植物인 선제비꽃(Viola raddeana)群落과 진퍼리용담(Grntiana scabra var. buergeri for stenophylla)이 Block 3(습지)에 있으므로 앞으로 이 區域은 注意깊게 保存되어야 할 것이다. 3. 土壤 水分含量이 最低 14.7%에서 最高 89.9%까지 分布하여 乾濕의 差異가 심하게 나타났다. 特히 調査 時期가 乾濕期인데도 土壤 水分含量이 70%가 넘는 곳이 3개소나 된다. 이 곳은 地下水位가 높아서 濕地이므로 濕地植物園을 造成해야 될 것이다. 植生의 造成狀態가 區域에 따라 變異가 심하게 나타났기 때문에 이 林地가 매우 不安定한 狀態에 있다고 볼 수 있을 것이다. Soil moisture contents and vegetation of the forest land planed to establish the Suweon Arboretum had been investigated to obtain some informations for establishing arboretum, and also for keeping the original vegetation composition data after the arboretum was established. The results obtained in this investigation could be summarized as follows. 1. In general, the coverage of Agrostis clavata var. nukabo was very high. The coverage of lxeris dentata and ixeris dentata var. albiflora were high except for very arid blocks. Coverages of Carex maximowiczii and Isachne globosa were high in wet blocks. The coverage of Zoysia japonica was high in very arid blocks and that of Carex lanceolata and Festuca ovina in arid blocks were high. 2. Soil moisture content was distributed from 14.7% to 88.9%. Especially the fact of the high moisture content (74.7, 77.5, 88.9%) in dry season implied that the ground water level of this area was high. The vegetation composition of this forest was varied, too. Therefore, it is considered that the stability of this forest was fragile.

樹木園 造成 豫定地를 對象으로 除草劑 處理가 生態系와 景觀에 미치는 衝擊을 줄이려고 努力하면서 不必要한 아까시나무를 效果的으로 枯殺시키는 方法을 찾는데 本 試驗의 目的을 두었다. 樹皮를 톱으로 긁어낸 것과 樹幹을 切斷한 것에 글라신液劑(근사미)와 글라신液劑에 2, 4-D를 섞은 것을 1985年 7月 하순에 1回 여러 濃度로 處理한 結果를 1985年 10月 17日에 조사하였는데 다음과 같은 結論을 얻었다. 1. 樹幹에 直接 處理하는 方法으로 處理木外에 다른 周邊 植生이 받는 被害는 나타나지 않았다. 2. 樹幹의 切斷部에 處理할 境遇 景觀의 破壤는 最小化되고 또 噴霧器로 藥劑를 枝葉에 撒布하는 境遇보다 除草劑의 所要量이 1/5 以下로 감소되었다. 3. 글라신液劑의 境遇 4倍液에서 100% 枯死되었으므로 100% 枯死시켜야 할 때는 4倍液을 쓰는 것이 분무기살포법보다는 經濟的으로 效率的일 것이다. 4. 글라신液劑에 2,4-D를 섞은 것은 5倍液에서 100% 枯死되어 2,4-D를 섞은 것이 더 效果的인 것으로 나타났다. 즉 現在 2,4-D의 값이 글라신液劑보다 더 低廉하고 若干의 2,4-D만 添加하면 되므로 글라신液劑와 2,4-D를 섞은 것을 5倍液으로 稀釋하여 處理하는 것이 더 經濟的일 것이다. This experiment was conducted at the Seoul National University Arboretum at Seodun-dong, Suweon, Kyeonggi-do, Korea (1) to find out methods killing Robinia pseudoacacia L. effectively and (2) to minimize ecological and aesthetic problems. Glycine and 2,4-D were treated in several concentration following the saw-scratching and cutting of stems on July 22 and 29, 1985. The results were measured on October 17, 1985.

증례 : 순환기 ; Warfarin에 의한 출혈 환자에서 POC장비로 확인된 CYP2C9과 VKORC1 유전자의 변이 조합 1예

김보성 ( Bo Sung Kim ),이동현 ( Dong Hyun Lee ),박혜경 ( Hye Kyong Park ),김민관 ( Min Kwan Kim ),김석현 ( Suk Hyun Kim ),김경한 ( Kyung Han Kim ),김무현 ( Moo Hyun Kim ) 대한내과학회 2013 대한내과학회지 Vol.85 No.1

현재 가장 널리 사용되는 항응고제인 warfarin은 적정 수준 도달에 있어 필요한 요구량이 다양한 외부인자들에 의해 영향을 받게 되는데 그 중 CYP2C9와 VKORC1 유전자의 변이는 과도한 항응고의 위험성과 관련이 있는 것으로 알려져 있다. 심방세동 및 류마티스성 판막질환으로 warfarin을 복용중이던 69세 여자 환자가 다발성 타박상과 혈종을 주소로 응급실로 내원하였으며 PT가 106초 이상으로 연장되어 있었던 것 외에 출혈을 유발할만한 다른 검사실 소견의 이상은 없었다. 저자들은 과도한 PT연장의 원인으로 CYP2C9와 VKORC1 유전자 변이의 가능성을 고려하여 검사를 시행하였으며 CYP2C9 *1/*3 이형접합체와 VKORC1 A/A 단일 염기 다형성 양성으로 나타났다. 다발성 타박상과 혈종은 PT 교정 후 호전되었으며 환자는 유전자 검사 결과를 토대로 적절한 용량의 warfarin을 처방 받은 후 퇴원할 수 있었다. 저자들은 연구 목적이 아닌 실제 warfarin을 복용하던 중 합병증으로 피부 밑 출혈이 발생한 환자에게서 유전자 검사용 POC device를 이용하여 손쉽게 CYP2C9와 VKORC1 유전자의 출혈성 조합을 확인하였기에 이를 관련 문헌고찰과 함께 보고하는 바이다. A 69-year-old female Korean patient was initially prescribed warfarin for the prevention of systemic thromboembolism due to atrial fibrillation. One month later, multiple bruises and subcutaneous hematomas were evident, and laboratory testing revealed a prolonged prothrombin time (PT) of > 106s. After admission, the PT was corrected via fresh frozen plasma transfusion and intravenous vitamin K infusion. We sought to determine the cause of the PT prolongation, suspecting that genetic cause may have had an effect on the variation in the warfarin dose requirement. A point-of-care gene test device (Verigene® system; Nanosphere, Northbrook, IL) revealed CYP2C9 *1/*3 heterozygosity and a VKORC1 A/A single nucleotide polymorphism. Although it is well established that CYP2C9 or VKORC1 gene polymorphisms can influence warfarin dose requirements, they can be easily neglected, with detrimental outcomes. Through our experience with CYP2C9 and VKORC1 polymorphism causing bleeding complications during warfarin treatment, we aim to emphasize the importance of pharmacogenetic testing to avoid this potential oversight.

Development of the DVH management software for the biologically-guided evaluation of radiotherapy plan

Kim, Bo-Kyong,Park, Hee-Chul,Oh, Dong-Ryul,Shin, Eun-Hyuk,Ahn, Yong-Chan,Kim, Jin-Sung,Han, Young-Yih The Korean Society for Radiation Oncology 2012 Radiation Oncology Journal Vol.30 No.1

Purpose: To develop the dose volume histogram (DVH) management software which guides the evaluation of radiotherapy (RT) plan of a new case according to the biological consequences of the DVHs from the previously treated patients. Materials and Methods: We determined the radiation pneumonitis (RP) as an biological response parameter in order to develop DVH management software. We retrospectively reviewed the medical records of lung cancer patients treated with curative 3-dimensional conformal radiation therapy (3D-CRT). The biological event was defined as RP of the Radiation Therapy Oncology Group (RTOG) grade III or more. Results: The DVH management software consisted of three parts (pre-existing DVH database, graphical tool, and $Pinnacle^3$ script). The pre-existing DVH data were retrieved from 128 patients. RP events were tagged to the specific DVH data through retrospective review of patients' medical records. The graphical tool was developed to present the complication histogram derived from the preexisting database (DVH and RP) and was implemented into the radiation treatment planning (RTP) system, $Pinnacle^3$ v8.0 (Phillips Healthcare). The software was designed for the pre-existing database to be updated easily by tagging the specific DVH data with the new incidence of RP events at the time of patients' follow-up. Conclusion: We developed the DVH management software as an effective tool to incorporate the phenomenological consequences derived from the pre-existing database in the evaluation of a new RT plan. It can be used not only for lung cancer patients but also for the other disease site with different toxicity parameters.
