Rats fed a vitamin E-deficient diet for 7--8 weeks postweaning showed no change in brain weight or the activity in brain of various enzymes involved in neurotransmitter synthesis and metabolism. Body and muscle weights were markedly reduced. Muscle choline acetyltransferase and acetylcholinesterase activities were significantly elevated on a protein basis, but the total amount of choline acetyltransferase/muscle was essentially normal and total acetylcholinesterase activity was slightly reduced. Total carnitine acetyltransferase and butyrylcholinesterase activities were markedly decreased. The results are quite different from those found in hereditary murine muscular dystrophy and suggest a myogenic etiology for the vitamin E-deficiency-induced condition.
