한국의 amatoxins 중독증은 강원 영서 지역이 호발지역으로 알려져 왔으며 최초로 보고된 원인버섯은 알광대버섯이었으나 현재까지 재 확인된 바가 없다. 원인버섯이 확인된 예로는 강원 영서지역이나 대전지역의 독우산광대버섯과 함께 1998년 경북 일원에서 발생한 집단 중독사고의 개나리광대버섯과 대전에서 발생한 1예에서 흰알광대버섯을 들 수 있다. 최근까지 amatoxins 중독증에 관해 보고된 국내의 문헌을 살펴보면 한국에서 발생하는 amatoxins중독증은 사망률에서 외국의 20-40% 와 큰 차이가 있는 것 처럼 보이나 사실상 전체적인 발생빈도나 사망률 등을 산출한 예가 없었을 뿐아니라, 높은 사망률의 원인이 무엇인지를 비교하는 것도 불가능하였다. 저자들은 국내에서 발생하는 amatoxins 중독증의 예방과 보다 효율적인 진단 및 치료를 위해 발생빈도나 사망률 및 원인버섯 등의 기초적인 조사와 함께 문헌을 통해 amatoxins 중독증에 대한 지견을 고찰하고자 하였다. 대상과 방법: 1999년 1년간 원인버섯 식별을 위해 의뢰되었던 증례들과 연례적 호발지역의 의료기관에서 병력 및 임상소견으로 amatoxins 중독증으로 진단 또는 추정된 증례들을 조사하였다. 원인버섯의 식별은 발생지역을 방문하여 원인버섯의 확보가 가능했던 소수의 증례에서는 외관과 현미경적 소견으로 원인버섯을 식별하였으며 원인버섯의 확보가 불가능한 증례에서는 특징적인 외관으로 추정되었다. 결과: 54명의 대상환자들 중 43명에서amatoxins 중독증으로 진단되었으며 그중 35명은 중등도 이상의 중독증으로 간주하였다. 중등도 이상의 중독증에서는 7명이 사망하여 20%의 사망률을 나타내었으며 원인버섯은 독우산광대버섯과 개나리광대버섯이 확인되었다. 흰알광대버섯은 확인되지 않았으나 사실상 독우산광대버섯과의 감별은 이루어지지 않았다. 4예에서는 원인버섯이 확인되지 않아 더 연구 되어야 한다. 사망례에서는 비사망군에 비해 혈소판이 유의하게 감소한 소견을 보였다. 전예에서 간이식등의 치료는 시행되지 않았으며 대부분 수액요법을 근간으로한 보존요법을 실시하였다. 결론: 한국의 amatoxins 중독증은 주로 강원 영서지역과 경북 일원에서 호발하고, 원인버섯은 외국과는 달리 독우산광대버섯과 개나리광대버섯이 주된 원인버섯이며, 1997년 까지의 증례보고를 대상으로한 70%의 사망률과는 달리 중등도 이상의 중독증례를 대상으로 하여도 사망률은 20%로 외국에 비해 높지 않다. 그러나 외국과 달리 간이식과 같은 보다 적극적인 치료를 시도한 예가 없는데, 대부분 갑자기 나빠지기 때문에 준비를 못하는 것이 원인이다. 따라서, 사망률을 더 낮추기 위해서는 혈액이나 소변과 같은 체액에서 단시간 내에 amatoxins을 측정할 수 있는 임상 검사법이 개발되어 조기 진단이 가능해져야 하며, 중독 초기에 나쁜 예후가 예측되는 심각한 증례를 선별하여 전문적인 치료를 받을 수 있는 기회를 제공해야 한다. 아울러 amatoxins 중독증에 대한 보다 정확한 통계를 산출하여야 할 것이다. 저자들은 본 연구에 1999년도에 발생한 대부분의 amatoxins 중독증의 증례가 포함되었으나 포함되지 않은 증례들이 다수 있다고 생각한다. 이러한 기초 조사를 철저히 하기 위해서는 전국 각지에서 발생하는 버섯중독 사고를 의뢰 또는 신고 할 수 있는 일원화 된 창구가 필요하리라고 사료된다. $quot;Background/Aims: From the review of Korean literature most fatal mushroom poisonings have been due to amatoxins with high mortality. So far there have never been investigations on the amatoxins poisonings such as annual incidence, mortality, common causal species, and endemic areas. This study was carried out to develop some basic statistics as part of studies for an effective management of amatoxins intoxications. Method: For the year 1999 authors collected cases of mushroom poisonings which had been mainly gathered from hospitals nation-wide. All of the cases with suggestive amatoxins poisonings were screened by symptomatology and laboratory findings. The causal species of mushrooms were identified grossly and microscopically. Results: A total of 54 victims with mushroom poisonings were evaluated. The causal mushroom toxins were diagnosed or strongly suggested as amatoxins in 43 of 54 victims. Eleven of 54 victims did not conform to the category of amatoxins intoxication due to absent or minimal elevation of aminotransferase. Mean age of the victims was 44.3 23.3 (range: 7-78) with male predominance (1.2 : 1). The causal species were confirmed, or strongly suggested, as Amanita virosa in 25 victims, Amanita subjunquillea in 14, and unknown species in 4. Thirty-five out of a total of 43 were regarded as moderate to severe intoxication (AST or ALT $gt; 1,000 IU/L) with 20% mortality. Most fatal victims showed marked thrombocytopenia (40,000 19,000/mm3) compared to non-fatal victims (109,066 42,245/mm3). A total of 88.4% of victims was developed in the Kangwon and Kyungpuk provinces. Both are west of the Taebaek Mountains (38/43). Conclusions: Although the common causal species for amatoxins poisonings in Korea are different from European countries and North America, the mortality is similar to that of those areas. In order to further reduce the mortality, bedside diagnostic methods using biological fluids and more effective herapy for liver failure should be established$quot;.

Epitaxial Growth of Boron-doped Si Film using a Thin Large-grained Si Seed Layer for Thin-film Si Solar Cells

Kang, Seung Mo,Ahn, Kyung Min,Moon, Sun Hong,Ahn, Byung Tae Korea Photovoltaic Society 2014 Current Photovoltaic Research Vol.2 No.1

We developed a method of growing thin Si film at $600^{\circ}C$ by hot wire CVD using a very thin large-grained poly-Si seed layer for thin-film Si solar cells. The seed layer was prepared by crystallizing an amorphous Si film by vapor-induced crystallization using $AlCl_3$ vapor. The average grain size of the p-type epitaxial Si layer was about $20{\mu}m$ and crystallographic defects in the epitaxial layer were mainly low-angle grain boundaries and coincident-site lattice boundaries, which are special boundaries with less electrical activity. Moreover, with a decreasing in-situ boron doping time, the mis-orientation angle between grain boundaries and in-grain defects in epitaxial Si decreased. Due to fewer defects, the epitaxial Si film was high quality evidenced from Raman and TEM analysis. The highest mobility of $360cm^2/V{\cdot}s$ was achieved by decreasing the in-situ boron doping time. The performance of our preliminary thin-film solar cells with a single-side HIT structure and $CoSi_2$ back contact was poor. However, the result showed that the epitaxial Si film has considerable potential for improved performance with a reduced boron doping concentration.

Systemic effects of fluoroscopically guided epidural steroid injection with dexamethasone

Kang, Woo Young,Lee, Joon Woo,Lee, Eugene,Kang, Yusuhn,Ahn, Joong Mo,Kang, Heung Sik The Korean Pain Society 2019 The Korean Journal of Pain Vol.32 No.3

Background: Epidural steroid injections (ESIs) have been widely used in managing spinal pain. Dexamethasone has recently emerged as a useful drug in this setting, relative to particulate steroids, although the associated systemic effects have not been fully elucidated. This study aimed to investigate the incidences and types of systemic effects after fluoroscopically guided ESI with dexamethasone. Methods: This retrospective study included 888 ESIs with dexamethasone (fluoroscopically guided at the cervical and lumbosacral levels) performed on 825 patients during January to June 2017. Data regarding systemic effects were collected via telephone interviews using a standardized questionnaire at 2 weeks after the procedure. Data on patient demographic, clinical, and procedural characteristics were collected and analyzed to identify factors that were associated with systemic effects. All statistical analyses were performed using the chi-squared test. Results: Among the 825 patients, 40 patients (4.8%) experienced systemic effects during the 2-week follow-up period. The most common systemic effect was facial flushing (12 patients, 1.5%), which was followed by urticaria (7 patients, 0.8%) and insomnia (7 patients, 0.8%). A history of spine surgery was significantly associated with the occurrence of systemic effects (P = 0.036). Systemic effects were significantly more common for injections at the cervical level than at the lumbar level (P = 0.019). Conclusions: Approximately 4.8% of the patients who underwent ESI with dexamethasone experienced minor and transient systemic effects. These effects were more common in patients who had undergone a previous spine surgery or received a cervical ESI.

Kang, Byeong-Mo,Lim, Yeong-Seog,Jeong, Woon-Jo,Kang, Byung-Woo,Ahn, Ho-Geun The Korean Institute of Electrical and Electronic 2014 Transactions on Electrical and Electronic Material Vol.15 No.5

We deposited TiAgN and ZrAgN nanocomposite coatings on pure Titanium specimens, by using arc ion plating (AIP) with single alloy targets. TiAg ZrAg alloy targets of 5 wt.%, 10 wt.% silver content by vacuum arc remelting (VAR), followed by homogenization for 2 hours at $1,100^{\circ}C$ in non-active Ar gas atmosphere and characterized these samples for morphology and chemical composition. We investigated the biocompatibility of TiAg and ZrAg alloys by examining the proliferation of L929 fibroblast cells by MTT test assay, after culturing the cells ($4{\times}10^4cells/cm^2$) for 24 hours; and exploring the antibacterial properties of thin films by culturing Streptococus Mutans (KCTC3065), using paper disk techniques. Our results showed no cytotoxic effects in any of the specimens, but the antibacterial effects against Streptococus Mutans appeared only in the 10 wt.% silver content specimens.
