title: Effect of pyridoxal administration on the contents of pyridoxal phosphate and gamma-aminobutyric acid in mouse brain.
abstract: Many mice treated with a high single dose of PL died in convulsions. The convulsions were very similar to those induced with some anti B6 in several ways: (1) a long latent period occurs betfore convulsions; (2) PLP levels in brain decrease; (3) GABA levels in brain, especially in synaptosomal fraction, decrease. The possibility that a deranged GABA metabolism in nerve ending may be a major cause of the convulsions is discussed.
