||The comparative neurotoxicity of subchronic exposure to 2-hydroxyethyl acrylate (HEA) and acrylamide (ACR) was evaluated using a functional observational battery (FOB) and neuropathology. Three dose levels of each compound (HEA: 3, 20, 60 mg/kg; ACR: 1, 4, 12 mg/kg) were administered intraperitoneally to male and female Long-Evans rats (n = 10/sex/dose level), 5 days/week for 13 weeks. Two vehicle control groups were also included. There were clear differences between the effects of HEA and ACR. ACR produced time- and dose-related changes in FOB measures of muscle tone and equilibrium, and produced axonal degeneration in peripheral nerves and within long tracts of the spinal cord. HEA exposure was also associated with changes in muscular function on FOB testing, but the magnitude of the effects was not as great as with ACR and not dose related.
