title: Regeneration of the sciatic nerve in mice and rats exposed to trichloroethylene.
abstract: The effects of trichloroethylene (TCE) on regeneration of the sciatic nerve after a crush lesion was tested in mice and rats. A lesion was made on nerves in unexposed animals and in animals pre-exposed to TCE for 20 days. Experimental animals were then exposed to TCE for an additional 4 days. Exposures were continuous at 150 or 300 ppm. Regeneration was measured by pinching the outgrowing nerve fibers. Regeneration was retarded in the TCE-exposed animals compared to the air-exposed controls. Mice were more sensitive to TCE exposure than rats. Liver weight increased in TCE-exposed mice but there was no correlation between this effect and that on nerve regeneration.
