Author information

  • 1Department of Biochemistry, Faculty of Medicine, University of Manitoba, Winnipeg, Canada.


Pyridoxine deficiency was induced in neuronally mature rats by combination of dietary deprivation and ingestion of 4-deoxypyridoxine. Overt signs of deficiency were evident. At this time the activity of glutamic acid decarboxylase as also the content of serotonin decreased in several areas of the brain. Catecholamine contents were unchanged from controls. Light microscopic observations indicated no difference in CNS myelin between the deficient and control animals. There was no difference between deficient and control groups in their auditory evoked responses.
