The author investigated the fractional determination of thiamine esters in the various organs and accumulation of ^<35>S in the subcellular components of liver and heart after administration of TPD-^<35>S (inner) to rats. The ^<35>S in the heart mitochondrial fraction increased remarkably after administration of TPD-^<35>S (inner) and replacement ratio of thiamine in mitochondrial fraction after administration of TPD-^<35>S (inner) was higher than in the case of thiamine-^<35>S.
