In the carpal tunnel syndrome (CTS), decreased conduction velocity (CV) of the median nerve in the forearm segment has been ascribed to an electrodiagnostic artefact rather than pathophysiological changes. Standard CV of the forearm segment is calculated by subtracting the distal latency, which may not represent an exact assessment of CV in the proximal(More)
We tested the hypothesis that the excitability of corticospinal neurons was altered by changes in PCO2. Magnetic stimulation was used to excite the neurons in the human motor cortex that give rise to the fast-conducting corticospinal pathway. The characteristics of the composite excitatory postsynaptic potentials (EPSPs) produced in individual spinal(More)
BACKGROUND We tested the effect of thiopental on the excitability of the corticospinal-motoneuron axis in normal human subjects. METHODS Magnetic stimulation was used to excite the neurons in the motor cortex which give rise to the fast conducting corticospinal pathway. The characteristics of the composite excitatory post-synaptic potentials (EPSPs)(More)
A series of acute and multiple dose toxicology studies were performed to support the clinical dose and to evaluate the systemic toxicity of an immunotoxin, H65-RTA. H65-RTA consists of a murine anti-CD5 monoclonal antibody and ricin A chain (RTA). The LD50 of H65-RTA was estimated to be between 60 and 62.5 mg/kg in the rat. H65-RTA was administered to the(More)
