Abstract：
:Effects of single and repeated doses of acrylamide on fast and slow axonal transport of radio labeled proteins following the injection of L-[4,5-3H] leucine have been studied in the optic system of male Sprague-Dawley rats. A single dose of acrylamide (100 mg/kg) had no effect, but higher concentrations (200-300 mg/kg) altered the distribution of fast axonally transported materials in optic nerves and optic tracts. Repeated doses of acrylamide (30 mg/kg/day, 5 days per week for 4 weeks) produced degeneration of tibial nerves but spared optic nerves and optic tracts. Fast axonal transport rate in optic axons was reduced by 50% (reduced to 4 mm/h from 8 mm/h) in acrylamide treated animals. Acrylamide also slowed the velocity of slow axonal transport of labeled proteins in optic axons to 1.0 mm per day from 1.3 mm per day. Since acrylamide impaired the rate of both fast and slow axonal transport in the absence of overt morphological damage, it can be concluded that deficit in axonal transport is an important factor in the pathogenesis of axonal degeneration in acrylamide neuropathy.
