Experimental allergic neuritis (EAN) was induced in guinea-pigs by intradermal injection of rabbit peripheral nerve emulsified in Freund's adjuvant. Both sciatic nerves were obtained between 12--24 hr after clinical symptoms were evident. Several fascicles from each nerve were isolated for histochemical studies with NADH-diaphorase (NADH) and acid(More)
Electromography, motor, sensory and mixed nerve conduction velocity, and H reflex were studied in four patients with ataxia-telangiectasia. The earliest and most striking electrophysiologial finding was the reduced amplitude of evoked nerve potentials. In the oldest patient, findings suggestive of spinal atrophy and mild reduction of the motor and sensory(More)
Hereditary motor and sensory neuropathy (HMSN) types I and III and chronic inflam-matory demyelinating polyradiculoneuropathy (CIDP) in developed countries are the most frequent causes of enlargement of peripheral nerves, " hypertrophic neuropathy " , 1 with clinically palpable thickened nerves, 2 visible on MRI. 3–6 They may even be the cause of spinal(More)
A case of infantile metachromatic leucodystrophy is described in which symptoms started at 1 year of age with weakness and hypotonus in the lower extremities. The electrophysiological status was typical of a polyneuropathy, showing fibrillation and a reduction of the nerve conduction velocity to 30 percent of the average for normal children of the same age.(More)
PURPOSE The aims of this study were to determine whether pretreatment plasma levels of cytokines and immune activation-associated molecules changed following treatment for AIDS-NHL with rituximab plus infusional EPOCH, and to determine whether pretreatment levels of these molecules were associated with response to treatment and/or survival. EXPERIMENTAL(More)
S U M M ARY The normal ratio between the amplitude of the sensory evoked potential (SEP) at the wrist on stimulating digits 1, 2, 3, and 5 was determined in 44 healthy adult subjects. The first digit had the larger amplitude, and the fifth digit the smallest SEP. The amplitude expresses the density of sensory innervation in each finger. The ratio between(More)
Maximum sensory conduction velocity, duration and amplitude of the sensory evoked potentials at the wrist on stimulating digits 1, 2, 3 and 5, were determined bilaterally in 21 left-handed subjects with an age range from 6 to 47 years. The amplitude of the sensory evoked potential at the wrist was larger in the right hand. This asymmetry is the reverse of(More)
