This presentation will summarize our clinical and pathological studies of the nervous system degeneration (distal dying-back axonopathy) in man and experimental animals produced by acrylamide monomer and certain hydrocarbon compounds (hexacarbons). "Distal axonopathy" is a term recently introduced to describe those diseases which are expressed as symmetrical, distal, axonal degeneration occurring concurrently in the peripheral nervous system (PNS) and in selected tracts of the central nervous system (CNS). Most of the humans and experimental animals with these conditions initially appear to have peripheral neuropathy. The human distal axonopathies include: (1) many of the naturally occurring, genetically determined, system disorders (spino-cerebellar degenerations), (2) certain nutritional disorders (thiamine deficiency), (3) uremic neuropathy, (4) the neuropathies associated with some malignancies (multiple myeloma), and ( 5 ) the toxic neuropathies induced by industrial chemicals (acrylamide, n-hexane, cresyl phosphate, arsenic, carbon disulfide), and pharmaceutical agents (nitrofuradantoin, isoniazid). Indeed, it now seems likely that distal axonopathy constitutes one of the fundamental and most common histopathological reactions of the mammallian nervous system to exogenous toxins.
