The object of the study was fungous diseases occurring on roots, leave sheaths and stem base of winter wheat in the two opposing cropping systems (organic and conventional). The observations were made in vegetation periods (2007-2009) in the fields of winter wheat in northern Poland. Every year on each plot of compared farming systems root rot occurred (Fusarium spp., Gaeumannomyces graminis and other fungi). For the period of 3 years the degree of disease injury on the roots of winter wheat grown in the conventional system in the vegetation period increased, while in the organic one remained on pretty the same level. On average a lot more affected roots, especially in the flowering stage, occurred on the winter wheat grown in the conventional system. Fusarium foot rot (Fusarium spp.) developed on the wheat during the entire vegetation period. It was the most dangerous root and foot rot disease (the highest indexes of injury). The mean degree of disease injury on leave sheath was on pretty the same level in the two farming systems, although in investigated vegetation periods differed a lot, whereas at the bases of stems the pathogen was on the higher level on the wheat in the conventional system. Also eyespot (Tapesia yallude) developed in the entire vegetation period of the winter wheat, but its intensity was much lower than in case of fusarium foot rot. Leave sheaths of the wheat grown in the conventional system were slightly stronger affected than those grown in the organic system. In the flowering stage the intensity of the disease in both farming systems became equal, while in the wax maturity it was considerably higher in the conventional system. Sharp eyespot (Rhizoctonia spp.) appeared relatively late and occurred only in two years of investigation. The intensiveness of the disease was definitely higher on the organic plots. Among the affected roots, taken in the stem elongation stage, from the organic system 28 cultures of fungi were isolated, and from the

Drug eluting balloons for the treatment of coronary artery disease: What can we expect?

引用

World Journal of Cardiology 2010年第9期2卷 257-261页

作者： Alexander Joost Volkhard kurowski Peter W Radke Medical Department Ⅱ UK S-H Campus Lübeck University of Lübeck D-23562 Lübeck Germany

Drug-eluting balloons (DEBs) represent an enhancement of the therapeutic repertoire for the interventional cardiologist. The therapeutic concept of DEBs is promising, notably on the basis of initial studies in patients with diffuse in-stent restenosis (ISR). At present, however, a number of questions regarding long-term efficacy and safety remain, specifically in indications other than diffuse ISR. The results of the evaluation of different substances, balloon systems and clinical indications will determine the long-term success of DEBs.

背景本文旨在观察不同速率输注瑞芬太尼是否会降低使脑电双频指数（bispectral index，BIS）≤50的丙泊酚EC50（半数有效浓度）值。方法将72例ASA分级Ⅰ或Ⅱ级拟行气管内插管并靶控输注（TCI）丙泊酚维持麻醉的成人患者，随机分为6组。瑞芬太尼输注速率分别为：B组0．1μg·kg^-1·min^-1,C组0．15μg·kg^-1·min^-1,D组0．2μg·kg^-1·min^-1,E组0．3μg·kg^-1·min^-1,F组0．4μg·kg^-1·min^-1,A组作为对照组不使用瑞芬太尼。在同一浓度瑞芬太尼组中，以第1例患者对TCI4μg/ml丙泊酚的反应决定岳一例患者的效应室浓度（Dixon的“序贯法”）。如果BIS〉50，后一例患者TCI丙泊酚的效应室浓度增加，如果BIS≤50，后一例患者TCI丙泊酚的效应室浓度则减少。同时研究了联合用药的血流动力学效应。结果EC50变化范围为2．4-2．9μg/ml.未发现瑞芬太毫对丙泊酚EC50的累加效应。但是未使用瑞芬太尼的空白对照组对丙泊酚的反应差异较大。使用瑞芬太尼组患者心率下降。结论瑞芬太昆输注不会减少无刺激麻醉患者丙泊酚需求量。在联合输注瑞芬太尼时不应当降低丙泊酚TCI浓度．
