Pulmonary anthracofibrosis may appear as a dark-gray color pigmentation on bronchus or pulmonary parenchyme and can result in pulmonary inflammation or fibrosis or emphysema. Some of the pigmentation can be accumulated in lymph node through lymphatics and result in lymphadenopathy. The causes of anthracofibrosis are aspiration of coal dust, or aromatic hydrocarbons, or air population, or silica dust and can be developed along with smoking or tuberculosis or lung cancer. We report 4 cases of pulmonary anthracofibrosis because we think it is necessary to distinguish pulmoary anthracosis acompanied by atelectasis, lymph node enlargement, and invasion to adjacent organ from lung cancer.

연구목적: 이 다기관 공동임상연구는 사용 중인 항정신병약물을 ’직접 교체 방법’또는 ’시작-감량 교체 방법’중 한 가지 방법으로 올란자핀으로 교체한 후, 안정성 측면에서 두 교체 방법 간의 비교와 교체후의 변화를 관찰하기 위한 것이다. 방법: 국내 13개 병원의 입원 및 외래에 내원한 환자들 중 ICD-10 지단기준으로 정신분열병에 해당되며, 임상적으로 항정신병약물 교체가 필요한 환자를 대상으로 하였다. 두 가지 교체 방법 중 한 가지를 무작위로 피험자에 적용하였으며, ’직접 교체 방법’에 배정된 경우에는 사용중인 항정신병약물을 일시에 중단하고 10㎎의 올란자핀을 바로 투여하였고, ’시작-감량 교체 방법’에 배정된 경우는 10㎎의 올란자핀 투여하고 2주에 걸쳐서 기존 약물을 감량하여 중단하였다. 올란자핀 사용기간은 총 6주이며, 용량은 5∼20㎎ 범위로 제한하였다. 한정성 평가를 위해서 체중, 생명징후, 자발적인 이상반응 복, 실험실 검사 그리고 Simpson-Angus Scale(SAS), Barnes akathisia rating scale(BARS), Abnormal involuntary movement scale(AIMS). Liverpool University neuroleptic side effect rating scale(LUNSERS)등을 이용하였다. 결과: 총 103명의 정신분열병 환자를 대상으로 하였다. 사용한 올란자핀의 용량, 벤조디아제핀의 병용률, 탈락률과 탈락 사유, 자발적인 이상반응 보고, 생명징후, 실험실 검사 그리고 대부분의 부작용 척도 상에서 임상적으로 의미 있는 차이를 두 교체 방법간에 발견하지 못하였다. 다만 AIMS의 감소는 ’직접 교체 방법’군에서 보다 적었고, 항콜린제의 병용률은 ’시작-감량 교체 방법’군에서 보다 많았다. 기저 상태에서 전체 피험자의 SAS와 BARS 점수는 각각 3.5점과 1.8점이었으며 70% 이상의 피험자가 고프로락틴 혈증을 보였다. 올란자핀으로 교체한 후, SAS, BARS, AIMS 점수의 유의한 감소가 있었으며 고프로락틴 혈증을 보인 피험자 분율도 약 30%이하로 감소하였다. 그러나 교체 방법과 상관없이 올란자핀 교체 후 유의한 체중 증가가 있었다. 결론: 이 연구를 통해 교체 방법에 관계없이 비교적 안전하고 용이하게 올란자핀으로 교체 할 수 있음을 알 수 있었다. 그리고 기존 항정신병약물을 올란자핀으로 교체함으로써 일부 부작용들을 줄일 수 있음을 간접적으로 관찰할 수 있었다. 하지만 이 연구는 여러 제한점과 문제점을 지니고 있기 때문에 보다 체계적인 연구를 통해 검정이 필요하리라 생각된다. Objectives: This multicenter clinical trial involving 13 hospital sites compared the safely of switching to olanzapine between ’direct switching method’ and ’start-tapering switching method’. Method: This study included both inpatients and outpatients who fulfilled the criteria for schizophrenia as defined in the ICD-10, and were in need to be appropriate for switching antipsychotics. Subjects were randomly assigned to one of the two switching methods. For ’direct switching method’group, previous antipsychotics were abruptly discontinued and 10㎎ of olanzapine was administered, and previous antipsychotics was gradually tapered for 2 weeks. Olanzapine was used for 6 weeks and the dose was adjusted within the range of 5-20㎎. The safety of switching to olanzapine was measured with vital sings including body weight, adverse events reported spontaneously, laboratory tests, and various scales such as Simpson-Angus Scale(SAS), Barnes Akathisia Rating Scale(BARS). Abnormal Involuntary Movement Scale(AIMS), and Liverpool University Neuroleptic Side Effect Rating Scale(LUNSERS). Results: 103 patients were switched to olanzapine in this study. The comparison between two switching methods did not show any significant difference in the dosage of olanzapine used, the concomitant use of benzodiazepine, the rate and reasons of drop-out, the adverse events, vital signs, laboratory tests, and most scales for measuring side-effects. However, the decrease in AIMS scores was significantly lower in ’direct switching method’ group, and the concomitant use of anticholinergics was comparatively greater in ’start-tapering switching method’ group. At baseline, SAS and BARS scores were 3.5 and 1.8 points respectively, and more than 70% of the subjects showed hyperprolactinemia. After switching to olanzapine, SAS, BARS, and AIMS scores were significantly decreased and the proportion of the patients with hyperprolactinemia was also decreased to less than 30%. However significant weight gain after the treatment of olanzapine was observed regardless of switching method. Conclusion: This study may suggest that switching to olanzapine can be done with relatively high safety regardless of switching methods and olanzapine can significantly decrease some side-effects induced by other antipsychotics.

<B>Objective</B><P>Interleukin-32 (IL-32) is a recently discovered cytokine that appears to play a critical role in human rheumatoid arthritis (RA). It is highly expressed in synovium and fibroblast-like synoviocytes (FLS) from RA patients, but not in patients with osteoarthritis (OA). This study was undertaken to assess IL-32 levels in RA synovial fluid (SF) and to investigate the secretion and regulation of IL-32 in RA FLS.</P><B>Methods</B><P>FLS and SF were obtained from the joints of RA patients. The secretion and expression of IL-32 and activation of signaling molecules were examined by enzyme-linked immunosorbent assay, immunoblotting, immunoprecipitation, reverse transcriptase–polymerase chain reaction, and small interfering RNA (siRNA) transfection.</P><B>Results</B><P>IL-32 levels were high in RA SF compared with OA SF. Furthermore, RA FLS expressed and secreted IL-32 when stimulated with tumor necrosis factor α (TNFα). TNFα-induced expression of IL-32 was significantly suppressed, in a dose-dependent manner, by inhibitors of Syk, protein kinase Cδ (PKCδ), and JNK and by knockdown of these kinases and c-Jun with siRNA. We also observed that PKCδ mediated the activation of JNK and c-Jun, and experiments using specific inhibitors and siRNA demonstrated that Syk was the upstream kinase for the activation of PKCδ.</P><B>Conclusion</B><P>The present findings suggest that IL-32 may be a newly identified prognostic biomarker in RA, thereby adding valuable knowledge to the understanding of this disease. The results also demonstrate that the production of IL-32 in RA FLS is regulated by Syk/PKCδ-mediated signaling events.</P>

New dry carbon nanotube coating of over-lithiated layered oxide cathode for lithium ion batteries
Mun, Junyoung,Park, Jin-Hwan,Choi, Wonchang,Benayad, Anass,Park, Jun-Ho,Lee, Jae-Myung,Doo, Seok-Gwang,Oh, Seung M. The Royal Society of Chemistry 2014 Journal of Materials Chemistry A Vol.2 No.46
<▼1><P>For high rate capability and energy density of lithium ion batteries, over-lithiated layered cathodes coated by multiwall carbon nanotube were prepared by a novel dry method without decay in the structure.</P></▼1><▼2><P>Carbon serves as one of the best coating materials for the cathode in lithium ion batteries. This is because it can solve two main problems, which are surface deterioration and poor electrical conductivity. However, the conventional carbon coating procedures and, chemical carbonization processes, are especially difficult to implement for the oxide cathode, which could thereby deteriorate the oxide structure. We prepared a new dry 100 nm-thick homogeneous multi-walled carbon nanotube (MWCNT) coating on the high-capacity oxide cathode material, Li1.17Ni0.17Co0.1Mn0.56O2, by applying shear stress without breaking down the crystal structure or morphology of the cathode. The electronic conductivity of the carbon composite with the coated sample is 170 mS cm<SUP>−1</SUP>, which is over 40 times as much as the conductivity of the pristine cathode containing the same amount of carbon. In addition, at a high current condition of 2450 mA g<SUP>−1</SUP>, a specific capacity of 103 mA h g<SUP>−1</SUP> is observed even with 3 percent of the carbon (in weight) constituting the coated MWCNT. The unconventionally improved performances are explained by the suppression of the electronic resistance and surface charge transfer resistance by electrochemical analyses.</P></▼2>

Radioprotective Effects of Aronia on Radiation Irradiated Rats
Hwan-Sik Mun(문환식),Jun-Haeng Lee(이준행) 대한방사선과학회(구 대한방사선기술학회) 2017 방사선기술과학 Vol.40 No.3
본 연구에서는 아로니아를 Rat에 경구 투여 후 방사선을 1회 전신 조사한 다음 혈액검사를 실시해 백혈구, 적혈구, 혈소판 등의 혈구세포의 변화 상태를 관찰하고 비교 분석하여 아로니아의 방사선 방어효과를 알아보 고자 하였다. 실험동물은 SD계 Rat 6주령 200∼250g 수컷 15마리를 이용하여 5마리를 하나의 군으로 정상군 (A), 5 Gy 대조군(B), 5 Gy 실험군(C)으로 설정하였고, 정상군(A)은 방사선 조사를 실시하지 않고, 대조군 (B)은 일반식 이를 투여하여 방사선조사를 하였고, 실험군(C)은 방사선조사 전 14일 동안 아로니아, 증류수 경구투여량(100 mg/kg/day)로 1일 2회씩 50 mg/kg/day로 각각 쥐에 14일 동안 경구 투여 후 방사선 조사(500 cGy/min로 5 Gy)를 하였다. 그 결과 정상군(A), 대조군(B), 실험군(C)에 따른 백혈구, 적혈구, 혈소판 차이를 비교해 본 결과 통계적으로 유의한 차이가 없었지만, 세부적으로 살펴보면, 림프구, 혈색소, 평균적혈구색소량에서 모두 정상군 (A)이 대조군(B), 실험군(C)에 비해서 평균수치가 높게 나타나 통계적으로 유의한 차이가 있음을 알 수 있었다. 림프구에서는 정상군(A)과 대조군(B), 정상군(A)과 실험군(C)간에 통계적으로 유의한 차이가 보였으며, 평균적 혈구색소량에서는 정상군(A)과 실험군(C)에서 통계적으로 유의한 차이를 보였다. 본 연구의 결과로 보아 방사선에 조사된 쥐에서 아로니아의 방사선방호효과가 전체적으로 백혈구, 적혈구, 혈소판 등은 없는 것으로 사료되었고, 부분적으로는 림프구, 혈색소, 평균적혈구혈색소량은 통계적 유의성이 있는 것으로 알 수 있었다. 이 실험을 바탕으로 향후 다양한 연구가 선행되어야 할 것으로 사료된다. The present study was intended to orally administer aronia to rats, irradiate radiation once to the whole bodies of the rats, and conduct blood tests to observe, compare, and analyze changes in blood cells, such as leukocytes, erythrocytes, and platelets, in order to examine the radioprotective effects of aronia. As experimental animals, 15 male Sprague-Dawley (SD) rats aged six weeks weighing 200∼250 g were tak-en and divided into the normal group (A) of five rats, the 5 Gy control group (B) of five rats, and the 5 Gy experimental group (C) of five rats. The normal group (A) was not i ̃ rradiated at all, the control group (B) was administered with general diets and irradiated, and the experimental group(C) was orally administered with 50 mg/kg/day of aronia two times per day to achieve a distilled water oral dose of 100 mg/kg/day and irradiated thereafter (5 Gy at 500 cGy/min) for 14 days. After the experiment, differences in leukocytes, erythrocytes, and platelets among the normal group (A), the control group (B), and the experimental group (C) were examined by comparing the counts of the blood cells and the results showed no statistically significant differences. However, on a detailed review, the normal group (A) showed statistically higher mean values for all of lym-phocytes, hemoglobin, and mean corpuscular hemoglobin as compared to the control group (B) and the ex-perimental group (C). Statistically significant differences in the counts of lymphocytes were shown between the normal group (A) and the control group (B), and between the normal group (A) and the experimental group (C); furthermore, statistically significant differences in mean corpuscular hemoglobin were shown between the normal group (A) and the experimental group (C). Given the results of the present study, in irradiated rats, aronia was generally considered as having no radio-protective effect on leukocyte, erythrocyte, and platelet while having statistically significant radioprotective effects on lymphocytes, hemoglobin, and mean corpuscular hemoglobin. Based on the present experiment, diverse studies should be conducted hereafter.
