As a part of a plan to improve the multifunctional hospital information system, Asan Medical Center has invented the COES (Clinician's Order Entry System) for the physicians which involves computerized TPN prescription. As an initial step, an outline of the system has been formulated after collection relevant materials from various sources including foreign materials. This project simplifies and standardizes COES between physicians and pharmacists. By introducing this system, we could minimize the possible errors during inputing the inscription and converting the requirements to the volumes to prepare the required medicine. Units of prescribed volume were automatically changed through the computerization of TPN order. This procedure can save time and man-power for preparing the medicine by using Automatic TPN Prescripter. All of these has encouraged us to seek more active TPN consultation for the systemical examination and monitor TPN inscription, and to provide patients with TPN of a good quality.

핵분열생성물중의 하나인 방사성스트론튬은 임신한 쥐에서 태반을 빠르게 통과하여 태아를 오염시킨다. 독성이 적은 천연착화제로서 마우스체내의 방사성스트론튬(Sr-85)의 제거에 효과적인 것으로 알려진 카이토산을 이용하여 Sr-85의 태반오염억제에 관한 연구를 하였다. 실험군은 일반식이를 공급한 대조군과 임신 17일째에 수용성카이토산을 피하(1% 카이토산), 구강(10% 카이토산), 복강(0.3% 카이토산)으로 주사한 카이토산군으로 분류하였다. 피하주사군은 Sr-85 오염후 카이토산을 주사한 군이며 복강과 구강주사군은 Sr-85 오염젼 15일간 카이토산을 공급한 군이었다. 출산과 동시에 어린마우스의 전신을 측정한 겨러과 출생후 7일째에 대조군이 2.8 ±0.3%의 전신축적율을 나타낸 반면 피하, 구강, 복강, 주사군은 각각 1.2 ±0.1%, 1.4 ±0.1%, 1.6 ±0.2%로 나타났다. 결과적으로 임신한 마우스에서 수용성카이토산은 방사성스트론튬의 태반오염을 유의하게 억제하는 것으로 사료된다. Radiostrontium passes the placental barrier in pregnant rodents very well. Chitosan, a natural nontoxic chelator, was reported to reduce whole body retention of radiostrontium in mice. The aim of the present study was to evaluate water soluble chitosan as a blocking agent of transplacental transfer of radiostrontium in pregnant mice. Twenty pregnant mice wre divided into four groups : control and three groups of chitosan treatment(groups 1 to 3). Sr-85(15KBq in 0.2ml saline) was subcutaneously injected into pregnant mice at the 17th day of pregnancy. In control mice, 0.2ml saline was given 5 hours after the injection of Sr-85. In group 1.1% water soluble chitosan was given subcutanously for two days, twice daily after the injection of Sr-85. In group 2, 10% water soluble chitosan was given orally for 15 days before conception. In group 3, 0.3% water soluble chitosan was injected intravenously for 15 days, once daily before conception. Gamma counting of newborns were done at days 0, 2 and 7 after their births. Whole body retention of Sr-85 in newborns of control mice at days 0, 2, 7 were 3.1 ±0.3%, 2.9 ±0.3%, 2.8 ±0.3% respectively. In experimental groups, whole body retention of Sr-85 was significantly lower thanthat of control(p<0.01) and no statistical difference was noted between them. In group 1, the values were 2.1 ±0.3%, 1.4 ±0.1%, 1.4 ±0.1%, respectively. In group 3, they were 2.1 ± 0.2%, 1.7 ± 0.2%, 1.6 ± 0.2%, respectively. In conclusion, the water soluble chitosan reduced transplacental contamination of radiostrontium in pregnant mice.

Seoung, Hyeog Gyu,Kim, Ji Hye,Choi, Jeong Cheon,Kim, Sang Mi,Kim, Sang Soo,Kim, Bo Hyun,Kim, In Ju,Song, Geun Am,Kim, Gwang Ha Chonnam National University Medical School 2012 CMJ Vol.48 No.1

<P>A 75-year-old woman who underwent a total thyroidectomy for papillary thyroid cancer 7 years previously presented with a palpable neck mass. Computed tomography (CT) showed two metastatic masses on the thyroid bed and another mass that looked benign originating from the esophageal wall. Endoscopic ultrasonography (EUS) showed a hypoechoic mass in the esophageal wall that looked similar to a gastrointestinal stromal tumor. The mass on the esophagus had intense fluorodeoxyglucose (FDG) uptake in positron emission tomography-computed tomography (PET-CT), which suggested the possibility of malignancy. Subsequently, after surgery, the mass in the esophagus was confirmed as a metastasis from the thyroid papillary carcinoma. Here we report this unusual case of papillary thyroid cancer that recurred as an esophageal submucosal tumor.</P>

Cadmium resistance in tobacco plants expressing the MuSI gene

Kim, Young-Nam,Kim, Ji-Seoung,Seo, Sang-Gyu,Lee, Young-Woo,Baek, Seung-Woo,Kim, Il-Sup,Yoon, Ho-Sung,Kim, Kwon-Rae,Kim, Sun-Hyung,Kim, Kye-Hoon The Korean Society of Plant Biotechnology 2011 Plant biotechnology reports Vol.5 No.4

MuSI, a gene that corresponds to a domain that contains the rubber elongation factor (REF), is highly homologous to many stress-related proteins in plants. Since MuSI is up-regulated in the roots of plants treated with cadmium or copper, the involvement of MuSI in cadmium tolerance was investigated in this study. Escherichia coli cells overexpressing MuSI were more resistant to Cd than wild-type cells transfected with vector alone. MuSI transgenic plants were also more resistant to Cd. MuSI transgenic tobacco plants absorbed less Cd than wild-type plants. Cd translocation from roots to shoots was reduced in the transgenic plants, thereby avoiding Cd toxicity. The number of short trichomes in the leaves of wild-type tobacco plants was increased by Cd treatment, while this was unchanged in MuSI transgenic tobacco. These results suggest that MuSI transgenic tobacco plants have enhanced tolerance to Cd via reduced Cd uptake and/or increased Cd immobilization in the roots, resulting in less Cd translocation to the shoots.

맥문동(Liriope platyphylla)은 한국과 중국에서 전통적으로 당뇨, 비만, 뇌신경질환, 천식 등의 치료를 위해 사용해온 치료제이다. 최근에 이들 맥문동으로부터 새로운 치료제를 개발하려는 노력이 활발히 진행 중이지만 아직도 유력한 치료후보제는 확보되지 않았다. 따라서 본 연구에서는 맥문동의 새로운 추출물을 이용하여 당뇨치료 제로서의 가능성을 평가하기 위하여 새로운 방법으로 10가지 후보물질을 추출하고 이들의 독성과 효능을 평가하였다. 그 결과 10가지 추출물 중에서 LP9M80-H가 인슐린 분비를 가장 많이 촉진하였고 다음으로는 LP-H, LP-M, LP-E과 LP9M80-C 등의 순서로 촉진을 하였으나 나머지는 인슐린 분비를 촉지하지 못하였다. 그러나 이들 물질은 인슐린 분비를 촉진하는 농도에서 강한 세포 독성을 나타내었다. 따라서 이들 물질 중에서 가장 효능이 좋은 LP9M80-H의 치료용 최적농도를 설정하였으며, 대략 100-25 ㎍/㎖가 최적농도로 결정되었다. 이러한 결과는 맥문동 추출물 중에서 LP9M80-H가 췌장 β-세포의 인슐린 분비능을 유도하는 새로운 당뇨치료 후보물질로서 향후에 사용될 가능성을 시사하고 있다. Liriope platyphylla has traditionally been used in Korea and China as a therapeutic drug for the treatment of coughing, sputum, neurodegenerative disorders, obesity, and diabetes. In an effort to assess the functions of a novel extract from Liriope platyphylla in diabetes therapy, the insulin secretion abilities of 10 extracts were screened via measurements of insulin concentration in the culture supernatant using an Insulin ELISA kit. The results of this assay showed the highest levels of insulin in the LP9M80-H treated group, followed by the LP-H, LP-M, LP-E and LP9M80-C treated groups, whereas other extracts did not induce insulin secretion in the HIT-T15 cells. However, the extracts capable of stimulating insulin secretion simultaneously evidenced high apoptotic activity as compared with other extracts. Therefore, one of these extracts, LP9M80-H, was initially selected as the optimal candidate for a therapeutic drug and its optimal concentration was determined. The results of the ELISA and MTT assay demonstrated that a concentration of approximately 100-125 ㎍/㎖ of LP9M80-H was optimal with regards to cell viability and insulin secretion in the HIT-T15 cells. These results suggest that LP9M80-H could be considered as an excellent candidate for a diabetes-therapeutic drug that could induce insulin secretion in pancreatic β-cells.

Potassium Channel Syndrome Caused by Nicorandil in Chronic Kidney Disease: A Case Report and Literature Review

( Ji-eun Kim ),( Seun Deuk Hwang ),( Seoung Woo Lee ),( Joon Ho Song ),( Kipyo Kim ) 대한전해질학회 2022 Electrolytes & Blood Pressure Vol.20 No.1

Nicorandil is an anti-anginal drug that is commonly used in the treatment of ischemic heart disease. Nicorandil acts as a nitrate donor and ATP-sensitive potassium channel agonist, inducing coronary artery vasodilation. Potassium efflux through ATP-sensitive potassium channels activated by nicorandil can cause refractory hyperkalemia, particularly in patients with chronic kidney disease (CKD). Here, we report the case of an 85-year-old man who presented with severe refractory hyperkalemia, despite proper medical management. His serum potassium level increased from 4.96 to 7.21mEq/L 7 days after restarting nicorandil. Hyperkalemia resolved shortly after discontinuation of nicorandil, which was presumed to be the offending drug. Previously, a few cases reported nicorandil-induced hyperkalemia called potassium channel syndrome in patients with CKD, and hyperkalemia can be reversed by ceasing nicorandil or using sulfonyl urea drugs. Given that CKD patients may have several contributing factors to this adverse event, clinicians should be aware of the risk of nicorandil-induced hyperkalemia, and medication review and drug discontinuation should be considered.

Kim, Woong Ji,Kim, So Ri,Choe, Yeong Hun,Lee, Ka Young,Park, Seoung Ju,Lee, Heung Bum,Chung, Myoung Ja,Jin, Gong Yong,Lee, Yong Chul The Korean Academy of Medical Sciences 2008 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.23 No.6

<P>Clear cell tumor of the lung is a rare and very unusual benign pulmonary tumor. As clear cell tumor of the lung contains abundant cytoplasmic glycogen, this tumor is called 'sugar tumor'. We report a case of sugar tumor in a 64-yr-old man presenting as a round pulmonary nodule. On dynamic computed tomography (CT) scans, the solitary pulmonary nodule showed early wash-in enhancement with an early washout pattern like a lung malignancy. The patient underwent wedge resection for the tumor. Pathologic examination, including immunohistochemical studies, revealed that the nodule was a benign clear cell tumor, so-called 'sugar tumor'. Because only a small number of cases have been reported previously, clinical aspects, radiological characteristics on dynamic contrast-enhanced CT, and differential diagnosis of the tumor are not well established. Herein we present a clear cell tumor of the lung and discuss the clinical, radiological, and pathological features of the tumor.</P>

성인 지역사회 폐렴의 원인 미생물에 대한 전향적 다기관 연구 : Legionella, Leptospira, Hantaan virus and Orientia tsutsugamushi

김민자,정희진,손장욱,심희선,박대원,박승철,우준희,강재명,김유겸,신완식,김양리,이환종,김지희 대한감염학회 2001 감염 Vol.33 No.1

Background : Despite rigorous investigations, the etiology of community-acquired pneumonia remains unknown in about 50% of hospitalized patients. The diagnosis of the etiological agent is becoming more challenging and more critical as number of newer pathogens have been recognized in recent years. In the 3-year period prospective study we investigated adult patients with community-acquired pneumonia for Legionella, Leptospira, Hantaan virus and Orientia tsutsugamushi as potential etiologic agents. Methods : A prospective multicenter study was performed from May 1997 to April 2000. A total of 431 patients with community-acquired pneumonia under the inclusion criteria were examined for specific microbial diagnosis; sputum culture and PCR, and serologic teats including indirect immunofluorescence antibody (IFA) test for Legionella, and hemagglutination tests for Leptosoira, Hantaan virus and O. tsutsugamushi. Etiologic diagnosis was determined on the basis of the review of case record forms and specific laboratory diagnostic criteria. Results : During the study period a total of 385 sputum and 283 serum samples were examined. Legionella pneumonia was diagnosed in 2.3% (10/431) of the cases examined : 1.4% cases with PCR-positive (5/367) and 2.1% with positive IFA test (6/283). Leptospirosis and scrub typhus were diagnosed in 0.4% (1/252) and 2.0% (5/252), respectively. All 5 cases with scrub typhus occurred in late fall, and rash or eschar was not found. None of cases was Hantaan virus infection. Conclusion : The results suggest that Legionella, Leptospira, and O. tsutsugamushi should be considered in the etiologic diagnosis and empirical antibiotic therapy of community-acquired pneumonia.
