Abstract |
The correlation between neuropathic damage and inhibition of neurotoxic esterase or neuropathy target enzyme (NTE) was examined in rats acutely exposed to Mipafox (N, N'-diisopropylphosphorodiamidofluoridate), a neurotoxic organophospate. Brain and spinal cord NTE activities were measured in Long-Evans male rats 1 hr post-exposure to various dosages of Mipafox (ip, 1-15 mg/kg). These data were correlated with histologically scored cervical cord damage in a separate group of similarly dosed rats sampled 14-21 days post-exposure. Those dosages (greater than or equal to 10 mg/kg) that inhibited mean NTE activity in the spinal cord greater than or equal to 73% and brain greater than or equal to 67% of control values produced severe (greater than or equal to 3) cervical cord pathology in 85% of the rats. |
