Abstract
Electrophysiological and histological studies have been performed on the vagus and splanchnic nerves of guinea pigs with experimental allergic neuritis. Slowing of conduction and dispersion of the compound action potential were consistent with the pathological changes of demyelination. In teased single fibre preparations, axonal degeneration was found more frequently than was expected and in the splanchnic nerves, the unmyelinated fibres appeared to have been indirectly involved. These findings in experimental allergic neuritis are relevant to the pathogenesis of autonomic dysfunction in the Landry-Guillain-Barré syndrome.
