| Abstract : Hens were given a single oral dose (0.235 mg/kg) of tri-o-cresylphosphate (TOCP) during chronic n-hexane treatment (200 mg/kg daily, 5 days/week). They were compared with other animals treated only with n-hexane or only with TOCP. Animals treated with a higher TOCP dose (1 ml/kg) were used as positive controls. The animals treated with both n-hexane and TOCP showed rapid development of severe ataxia. The rate of the ataxia development was similar to that of the positive controls but with earlier onset of the first signs and with less loss of body weight. However, animals treated only with n-hexane, under the same conditions, showed only reversible weakness and sedative effects, and those treated only with TOCP showed slow and slight ataxia development. The n-hexane- and TOCP-treated hens showed axonal swelling with myelin retraction associated with Ranvier's nodes, which is characteristic of long hexacarbon exposure. Some internodal swellings were also observed but less frequently than the paranodal swellings. The time course of the ataxia development was similar to an organophosphorus-induced delayed neuropathy (OPIDN); however, the light microscopy observation more closely resembled hexacarbon neuropathy. The results suggest a potentiation effect of n-hexane and TOCP neurotoxicities which could be related to some human occupational neuropathies. |
