罗库溴铵术后残留作用研究--与维库溴铵和阿曲库铵的比较

目的 :研究依据临床指征拔除气管导管后罗库溴铵、维库溴铵和阿曲库铵的肌松残留情况。方法 :6 0例择期手术患者随机分成维库溴铵 (VEC)、罗库溴铵 (ROC)及阿曲库铵 (ATR)三组 ,每组 2 0例。静吸复合麻醉。肌松药首量 :VEC组 12 0 μg/kg ;ROC组 6 0 0 μg/kg ;ATR组 5 0 0 μg/kg。术中用四个成串刺激 (TOF)监测肌松 ,当其值 (TOFR)至 0 .1时追加肌松药 1×ED 95。结果 :维库溴铵末次给药作用时间长于罗库溴铵 (P <0 .0 1)和阿曲库铵 (P <0 .0 5 ) ;拔管时各组TOFR及TOFR <0 .75的例数均无统计学差异 (P >0 .0 5 )。阿曲库铵残留时间短于维库溴铵 (P <0 .0 1)和罗库溴铵 (P <0 .0 5 )。结论 :非去极化肌松药罗库溴铵与维库溴铵和阿曲库铵一样 ,用药后若依据临床指征拔除气管导管都有发生术后肌松残留的危险。

Evidence of Coulomb blockade behavior in a quasi-zero-dimensional quantum well on TiO2 surface

Line defects on the surface of rutile TiO₂(110) form in pairs separated by 1.2 nm creating a quantum well. The well is effectively closed by the presence of two charged structures at both ends separated by a distance in the 10–20 nm range. As expected for quantum confinement a long period oscillatory feature of the local density of states is observed and attributed to the formation of discrete quantum states inside the system. It is at first glance surprising that the lowest energy quantum state of the well can be observed at room temperature. The properties of the quantum state cannot be explained in an independent-electron, band-like theory. Instead, electron-electron correlation must be included to give a satisfactory picture of the spatial distribution of the charge density. Theory predicts charging energies of 1.30 eV and 1.14 eV for quantum well lengths of 14 nm and 16 nm, respectively, in good agreement with a classical calculation and the size dependence of the capacitance. This observation opens up the possibility of experimentally imaging the transition from a Coulomb blockade localized in a zero-dimensional system to an independent-particle or band-like behavior in an extended one-dimensional system.

Interaction of monovalent cations with tetrodotoxin and saxitoxin binding at sodium channels of frog myelinated nerve

Na currents and Na-current fluctuations were measured in myelinated frog nerve fibres to study interactions between monovalent externally applied cations and the binding of the Na-channel blockers tetrodotoxin (TTX) or saxitoxin (STX). Adding 110 mM NaCl to Ringer's solution increased the maximum peak Na conductance by a factor of 2.51 in the presence of 12 nM TTX and by a factor of 2.43 in the presence of 4 nM STX. According to the analysis of Na-current fluctuations this increase of the Na conductance is mainly caused by an increase of the number N of unblocked Na channels per node, while the conductance of a single channel saturates in the hyperosmolar solutions. The increase of N is interpreted by displacement of TTX or STX from Na channels by external Na⁺. Relief of TTX blockage was also observed by adding 100 mM chloride salts of Li⁺, hydrazine⁺, guanidine⁺ and K⁺ to Ringer, but not in Ringer + 110 mM tetramethylammonium chloride or 250 mM sucrose. The increase of N by the external cations is a saturating function of the permeability of the Na channel to these ions. The results are interpreted by a toxin receptor in a superficial prefilter to the Na channel, which contributes to cation discrimination at the outer channel region.
