title: Fast axonal transport rates are unchanged in 6- and 24-month F344 rats.
abstract: The maximum rate of fast axonal transport in motor axons at 6 and 24 months was measured in F344 rats. Tritiated proline was injected near sciatic motoneurons and rats were killed after 2-5 h. Nerves were processed for liquid scintillation spectroscopy and fast transport rates calculated. The rates, in 6- and 24-month rats, were 373 +/- 12 mm/day and 368 +/- 10 mm/day, respectively. Thus, the maximum fast transport rate is unchanged with age in F344 rats.
