Abstract Since the spinal cord and peripheral nerves are vulnerable to the effects of vitamin E deficiency, vitamin E concentrations in various discrete regions of these parts of the nervous system of the rat were determined. Furthermore, as acrylamide toxicity and vitamin E deficiency share some neuropathological features, tissue vitamin E concentrations in acrylamide-treated rats were also studied. Male Sprague Dawley rats (200 to 250 g body weight) were fed normal rat chow with or without 0.03% acrylamide in their drinking water. After 24 days, the animals were sacrificed and the tissues assayed for vitamin E by a liquid chromatographic method. Vitamin E concentrations decreased from cerebral cortex to spinal cord with no concentration gradients between different levels of the spinal cord. Sciatic nerve concentration of alpha tocopherol was as high as that of cerebral cortex, and the former also contained measurable amounts of gamma tocopherol. Vitamin E concentrations in the majority of nervous tissue samples remained unchanged with acrylamide treatment.
