The similar experiments with the blood cells were carried out with the tissues of various organs for the reduction and the uptake of TPD compared with the ordinary thiamine and the following results were obtained. TPD was taken up in a large amount to the tissues and the main factor which reduced TPD to thiamine in the organs seemed to be the SH radical as in the case of the blood cells. The action of this factor was markedly inhibited by the addition of PCMB. On the contrary to this phenomenon the amounts of thiamine taken up into the various tissues was small and hardly affected by the addition of PCMB in the case of the ordinary thiamine.
