STUDIES ON THE NUTRITIONAL VALUE OF ALLIUM PLANTS : (XVVIII) THE AFFINITY OF THIAMINE PROPYLDISULFIDE-^<35>S AND THIAMINE-^<35>S TO THE NEURAL TISSUES

Abstract

The distributions of ^<35>S in various neural tissues, such as cerebrum, cerebellum, brain stem, spinal cord and ischiatic nerve, were determined after an intravenous injection of thiamine propyldisulfide (TPD)-^<35>S (inner or outer) or thiamine-^<35>S in rabbits. It was clarified that thiamine in neural tissues was turned over by injected radioactive thiamine very slowly. The retentions of ^<35>S of TPD-^<35>S (inner) or thiamine-^<35>S in the neural tissues were longer than that of ^<35>S of TPD-^<35>S (outer).
