Five patients with acute massive pulmonary embolism were treated with streptokinase administered via the pulmonary artery as close as possible to the embolus. Streptokinase (Awelysin) was infused at a loading dose of 250,000 IU followed by a maintenance dose of 100,000 IU/hour under haemodynamic and angiographic control. In four of five patients (two patients with cardiogenic shock) the clinical signs, pulmonary artery pressure and the angiographic findings improved or they normalised within 5-12 hours. In one patient with recurrent embolisation over three weeks the clinical condition improved gradually, although the angiographic findings improved only slightly. The results demonstrate that local thrombolysis of acute massive pulmonary embolism is a highly effective form of treatment. 相似文献

The stationary state of the self-organizing sensory mapping of Kohonen is investigated. For this purpose the equation for the stationary state is derived for the case of one-dimensional and two-dimensional mappings. The equation can be solved for special cases, including the general one-dimensional case, to yield an explicit expression for the local magnification factor of the map. 相似文献

Metacognitive reflections on one''s current state of mind are largely absent during dreaming. Lucid dreaming as the exception to this rule is a rare phenomenon; however, its occurrence can be facilitated through cognitive training. A central idea of respective training strategies is to regularly question one''s phenomenal experience: is the currently experienced world real, or just a dream? Here, we tested if such lucid dreaming training can be enhanced with dream-like virtual reality (VR): over the course of four weeks, volunteers underwent lucid dreaming training in VR scenarios comprising dream-like elements, classical lucid dreaming training or no training. We found that VR-assisted training led to significantly stronger increases in lucid dreaming compared to the no-training condition. Eye signal-verified lucid dreams during polysomnography supported behavioural results. We discuss the potential mechanisms underlying these findings, in particular the role of synthetic dream-like experiences, incorporation of VR content in dream imagery serving as memory cues, and extended dissociative effects of VR session on subsequent experiences that might amplify lucid dreaming training during wakefulness.This article is part of the theme issue ‘Offline perception: voluntary and spontaneous perceptual experiences without matching external stimulation''. 相似文献
