Fluconazole의 진균 감염증 예방 효과와 안전성에 관하여 3개 대학병원에서 관해유도화학요법을 받는 급성 백혈병환자를 대상으로 무작위 배정법과 너도나도 누가림법에 의하여 연구하였다. 모두 62명의 환자에게 fluconazole(100㎎ bid) 또는 nystatin(1,000,000IU/day)을 무작위로 투여하였다. 투약은 관해유도화학요법과 같은 날짜에 시작하여 호중구수가 1,000㎣이상으로 회복되거나 진균 감염증이 확인되거나 의심되어 Amphotericin-B를 시작하거나, 약과 관련된 부작용이 나타날 때까지 계속하였다. 진균 colonization은 fluconazole군에서 감소하였으나 nystqatin군에서는 증가하였다, 표재성 진균감염증으로 nystatin군에서 C. albicans 진균혈증 1례와 C.parasilosis 진균혈중 1례가 발생하였다. 경험적 항진균요법으로 Amphotericin-B를 투여한 경우는 fluconazolerns 34명중 7례(21%), nystatinrns 28명중 10례(36%)였다(p<0.05). Fluconazole군과 nystatin군 사이에 부작용이나 사망률에 차이는 없었다. 결론적으로, fluconazole은 관해유도화학요법을 받는 급성 백혈병환자에서 진균의 colonization을 줄이는데 효과적이고 안전한 항진균제이다. We made a randomized, double-blind, multicenter trial to compare the efficacy and safety of fluconazole with nystatin for prevention of fungal infections in patients with acute leukemia. Sixty-two adult undergoing remission induction chemotherapy for cute leukemia were enrolled. Patients were randomly assigned to receive either fluconazole (100㎎ bid) or nystatin(1,000,000IU×6/day) with corresponding placebo. The study drug was started in initiation of chemotherapy and continued until recovery of neutrophil counts(>1,000/㎣), development of proven or suspected invasive fungal infection, or the occurrence of drug-related toxicity. Fungal colonization decreased in fluconazole(F) group, however increased in nystain(n) group. Superficial fungal infection occurred in 1 of 34 F group, whereas invasive fungal infection developed in 3 of 28 N group. Empirical amphotericin-B therapy was given in 7 of 34(21%) F group and 10 of 28(36%) N group(p>0.05). The incidence of drug-related side effects and overall moratlity were similar in both study groups.

Nafamostat mesilate (NM) is a serine protease inhibitor with anticoagulant and anti-inflammatory effects. NM has been used in Asia for anticoagulation during extracorporeal circulation in patients undergoing continuous renal replacement therapy and extra corporeal membrane oxygenation. Oxidative stress is an independent risk factor for atherosclerotic vascular disease and is associated with vascular endothelial function. We investigated whether NM could inhibit endothelial dysfunction induced by tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$ ). Human umbilical vein endothelial cells (HUVECs) were treated with TNF-${\alpha}$ for 24 h. The effects of NM on monocyte adhesion, vascular cell adhesion molecule-1 (VCAM-1) and intracellular adhesion molecule-1 (ICAM-1) protein expression, p38 mitogenactivated protein kinase (MAPK) activation, and intracellular superoxide production were then examined. NM ($0.01{\sim}100{\mu}g/mL$) did not affect HUVEC viability; however, it inhibited the increases in reactive oxygen species (ROS) production and p66shc expression elicited by TNF-${\alpha}$ (3 ng/mL), and it dose dependently prevented the TNF-${\alpha}$ -induced upregulation of endothelial VCAM-1 and ICAM-1. In addition, it mitigated TNF-${\alpha}$ -induced p38 MAPK phosphorylation and the adhesion of U937 monocytes. These data suggest that NM mitigates TNF-${\alpha}$ -induced monocyte adhesion and the expression of endothelial cell adhesion molecules, and that the anti-adhesive effect of NM is mediated through the inhibition of p66shc, ROS production, and p38 MAPK activation.

<P>This study examined the crystallization behavior of electroless Ni-P UBM with an medium phosphorous content (∼15 at%) induced by a single and step heat treatment using <I>in-situ</I> transmission electron microscopy (TEM). Different heat treatment processes affected the crystallization behavior of electroless Ni-P UBM. After single heat treatment at 300°C for 60 min, the electroless Ni-P UBM contained Ni and Ni<SUB>3</SUB>P. In addition to Ni and Ni<SUB>3</SUB>P, more complex Ni-P compounds, such as Ni<SUB>12</SUB>P<SUB>5</SUB> and Ni<SUB>5</SUB>P<SUB>2</SUB> formed in the electroless Ni-P UBM resulting from a step heat treatment at 150°C for 60 min followed by 300°C for 60 min.</P>
Inkjet-Printed Multiwavelength Thermoplasmonic Images for Anticounterfeiting Applications
Kang, Hongki,Lee, Jee Woong,Nam, Yoonkey American Chemical Society 2018 ACS APPLIED MATERIALS & INTERFACES Vol.10 No.7
<P>Inkjet printing of thermoplasmonic nanoparticles enables instantaneous, large-area heat pattern generation upon light illumination from distance. By printing multiple metal nanoparticles of different shapes overlaid, we can fabricate multiwavelength thermoplasmonic images, which generate different heat patterns from,a single printed image depending on the wavelength choice of light. In this work, we propose a novel multiwavelength thermoplasmonic image printing process that can be used for anticounterfeit technology. With this technology, 'printed thermoplasmonic labels' allow fully secured anticounterfeit inspection procedure. Input stimulus of near infrared or infrared light illumination and output signal reading of thermal patterns can be both completely invisible. Wavelength selective photothermal effect also enables the encryption of the contained information, which adds more complexity and thus higher security.</P>
