Measurements of binocular depth inversion using a stereoscopic slide projection with polarized light were performed in healthy volunteers before and after cannabis intake. Since binocular depth inversion represents an illusion occurring in the perception of semantically meaningful objects projected in a 3-D inverted fashion, the hypothesis can be tested(More)
BACKGROUND Poisoning with organophosphorus (OP) insecticides is a major global public health problem, causing an estimated 200,000 deaths each year. Although the World Health Organization recommends use of pralidoxime, this antidote's effectiveness remains unclear. We aimed to determine whether the addition of pralidoxime chloride to atropine and supportive(More)
BACKGROUND Although more than 100 organophosphorus insecticides exist, organophosphorus poisoning is usually regarded as a single entity, distinguished only by the compound's lethal dose in animals. We aimed to determine whether the three most common organophosphorus insecticides used for self-poisoning in Sri Lanka differ in the clinical features and(More)
The anesthetic excitement phase occurring during induction of anesthesia with volatile anesthetics is a well-known phenomenon in clinical practice. However, the physiological mechanisms underlying anesthetic-induced excitation are still unclear. Here we provide evidence from in vitro experiments performed on rat brain slices that the general anesthetic(More)
BACKGROUND Many organophosphorus (OP) insecticides have either two O-methyl or two O-ethyl groups attached to the phosphorus atom. This chemical structure affects their responsiveness to oxime-induced acetylcholinesterase (AChE) reactivation after poisoning. However, several OP insecticides are atypical and do not have these structures. AIM We aimed to(More)
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT * Acute alcohol intoxication often complicates acute organophosphorus pesticide poisoning. * No data are available on how alcohol intoxication affects outcome in acute organophosphorus pesticide poisoning. * In particular, the relationships between plasma alcohol concentration and plasma organophosphorus(More)
Isoflurane and sevoflurane are commonly used volatile anaesthetics. Although acting via similar cellular mechanisms, the effect of different volatile anaesthetics on synaptic plasticity might differ. In the present study, using acute murine brain slice preparations, we compared the effects of isoflurane and sevoflurane on synaptic transmission and synaptic(More)
Nicotine has wellknown, unpleasant side effects, e.g., transient dizziness, nausea, and nicotine-induced nystagmus (NIN). To investigate factors influencing these effects, we addressed three questions: (1) Is the intensity of dizziness, nausea, NIN, and unsteadiness dependent on nicotine dosage? (2) Does the intensity of perceptual, ocular motor, vegetative(More)
Volatile anaesthetics have a variety of effects on the myocardium, namely a negative inotropic effect and a catecholamine sensitizing effect. The present study was designed to see if the hydrocarbon anaesthetics interact specifically with subcellular targets of the myocardial cell, by examining the effects of halothane in the presence of positive inotropic(More)
With collaboration of the study groups from Tübingen, Munich and Kiel and consideration of the results of Bonnichsen et al 1968, alcohol elimination curves of 98 alcoholics were subjected to a joint evaluation for determination of the beta 60 values. The average elimination rate was 0.21 g/kg/h (s = 0.05 g/kg/h). By analogy to average beta 60 values and(More)
