Reorganization of Axonal Cytoskeleton Following β, β′-Iminodipropionitrile (IDPN) Intoxication

  • Sozos Ch. Papasozomenos


β,β ′-Iminodipropionitri1e (IDPN), NH=(CH2CH2CN)2, is a synthetic compound closely related to the osteolathyrogen B-aminopropionitrile (NH2CH2CH2CN). Intoxication of various experimental animals with IDPN produces the excitement, circling and choreathetosis (ECC) or waltzing syndrome (Selye, 1957), a permanent symptom complex indicating irreparable damage to the central nervous system (CNS). Early histopathological studies have described large, amorphous bodies in the anterior horn cells of spinal cord and in other large neurons throughout the nervous system. These amorphous bodies were originally misinterpreted as degenerated neuronal perikarya and were called “ghost cells” (Bachhuber et al., 1955; Ule, 1962). It was shown subsequently by Chou and Hartman (1964; 1965) that the “ghost cells” were actually huge balloons and swollen axons connected to the cell body by an apparently normal initial segment (Fig. 1). They suggested that “axostasis,” caused by a “plug” of particulate organelles in the proximal axon, produced the axonal swellings.
