Über die Wirkung des Rivanols bei septischen Krankheiten, wenn intravenös injiziert

Es ist praktisch erwiesen, dass das Rivanol als Tiefenantisepticum von günstiger Wirkung ist. In letzter Zeit wird es auch als intravenöse Injektion angewandt. Auch ich habe den therapeutischen Wert der intravenösen Injektion des Rivanols festgestellt. Ich habe diesen Injektionen 0.1% Losungen des Rivanols benützt und zwar gewöhnlich an einem Tage 50ccm und als gesammt Dosis eine Menge von 100-800ccm, durchschnittlich 275ccm. Zur Herabsenkung des Fiebers bedürfte es eines Zeitverlaufes von 3-8, durchschnittlich 5, 7 Tagen. Um die Blutinfektion negativ zu gestalten, bedarf es eines Zeitverlaufes von 4-18, durchschnittlich 8 Tagen. Ich habe weiterhin in Tierversuchen die Wirkungsweise des Rivanols bei septischen Krankheiten, wenn intravenös injiziert, festzustellen versucht. d. h. Ich habe bei Kaninchen Staphylokokkensepsis hervorgerufen und darauf die Veränderungen des Retikuloendothelial-Systems durch Rivanol-injektionen festgestellt. Aus meinen Untersuchungen scheint hervorzugehen, dass die intravöse Injektion von Rivanol bei septischen Krankheiten seine Wirkungsweise nicht indirekt durch eine Wirkung auf die körperschutzenden Organe, sondern vielmehr eine direkt bakteritide ist

Proton Energy Loss Spectroscopy for Surface Monolayer Analysis

A survey is given of recent advances in the use of high-energy proton backscattering spectroscopy or proton energy loss spectroscopy (PELS) under the glancing incidence geometry for monolayer-sensitive analysis. Two theories of the energy loss involved in the PELS are described, based on the continuous and impact parameter dependent slowing down models. The latter theory leads to the azimuthal angle dependence of the energy loss. It is also shown that this technique is applicable to underlayer composition analysi

Pressure Tuning of an Ionic Insulator into a Heavy Electron Metal: An Infrared Study of YbS

Optical conductivity [$\sigma(\omega)$] of YbS has been measured under pressure up to 20 GPa. Below 8 GPa, $\sigma(\omega)$ is low since YbS is an insulator with an energy gap between fully occupied 4$f$ state and unoccupied conduction ($c$) band. Above 8 GPa, however, $\sigma(\omega)$ increases dramatically, developing a Drude component due to heavy carriers and characteristic infrared peaks. It is shown that increasing pressure has caused an energy overlap and hybridization between the $c$ band and 4$f$ state, thus driving the initially ionic and insulating YbS into a correlated metal with heavy carriers

Photosynthetic Responses of Four Legume Crops to Fluctuations of Evaporative Demand Following the Rainy Season

In the typical climate of East Asia, summer crops develop large shoots with relatively poor root systems during the rainy season, leading to restricted photosynthetic activity in the following summer months. The objectives of the present study were 1) to determinate if there are specific differences in the photosynthetic responses of four legume crops to daily fluctuations of evaporative demand and 2) to identify physiological attributes responsible for the differences. Soybean, azuki bean, cowpea and peanut were grown in a field, and apparent leaf photosynthetic rate (AP) and gas exchange parameters as well as water potential and transpiration rate were measured at midday on three consecutive summer days. When leaf-to-air vapor pressure deficit (VPD_) varied from 1.72 to 3.44 kPa during the experimental period, the four species responded differently. The AP of soybean and that of azuki bean decreased with increasing VPD_ over a range of 1.72 to 3.44 kPa, whereas the activities of cowpea and peanut were greatest at VPD_ around 2.53 kPa. The leaf water potentials of soybean, azuki bean and cowpea reached minima at VPD_ around 2.53 kPa, while that of peanut was fairly constant over the VPD_ range of 1.72 to 3.44 kPa. The transpiration rates of soybean, azuki bean and cowpea were greatest at VPD_ around 2.53 kPa and decreased beyond that range of VPD_, while peanut transpired actively with increasing VPD_. AP of soybean was correlated with leaf water potential, whereas that of cowpea and peanut was correlated with transpiration rate. With respect to water relation, peanut was most tolerant to increasing VPD_ among the four species tested, presumably because it maintained higher water potential and transpiration rate than the other species under the condition of high VPD_
