The comparative study of the distribution of orally administered O-benzoylthiamine disulfide-^<35>S (BTDS-^<35>S) and thiamine-^<35>S has been carried out in baby and adult mice by means of whole body autoradiographic methods. The autoradiogram revealed that the uptake of ^<35>S was higher and more rapid in the liver, the heart, the lung and the other tissues at short intervals (30-60 mins.) when BTDS-^<35>S was administered than when thiamine-^<35>S was given. This suggests that BTDS is more readily absorbed from digestive tract than thiamine.
