  • Title: The axon reaction in spinal ganglion neurons of acrylamide-treated rats.
    Author: Jones HB, Cavanagh JB.
    Journal: Acta Neuropathol; 1986; 71(1-2):55-63. PubMed ID: 3022537.
    Abstract:
    Rats were given acrylamide in doses of either 30 or 50 mg/kg (5 days each week) for up to 3 weeks and killed at weekly intervals. The right sciatic nerve was tied tightly at the level of the major trochanter 4 days before killing the animals by perfusion fixation when ipsilateral and contralateral sensory ganglia (L5 and L6) were removed. The effects on neuronal perikarya of axotomy alone, of acrylamide alone and of these combined were studied by light and electron microscopy. The responses to axotomy and to acrylamide intoxication shared certain features, namely peripheral Nissl substance and to a lesser degree nuclear eccentricity, nucleolemmal crenation and mitochondrial enlargement. Neurofilament loss was present only with acrylamide. In combined axotomy and acrylamide all these five features were prominent. These findings indicate firstly that the individual responses to axotomy and to acrylamide, while sharing several features, are subtly different and secondly that acrylamide appears to impede the vital neuronal responses directed towards repair of the axon.
