鉄の大腸内吸収に及ぼすB₁, TPD, 葡萄糖並にウレタンの影響に就て

抄録

In the present paper, the authors investigated the influences of vitamin B₁ (B₁ hereafter) or thiamine propyl disulfide (TPD hereafter) on the absorption of ferrous sulfate in the large intestine. Further, they investigated the influence of the administration of vitamin combined with urethane or with glucose on the absorption of iron. The followings are the results thus obtained.
1) In the cases of the administration of ferrous sulfate combined with B₁ or with TPD as enema, the absorption of iron and B₁ in the large intestine was found not specifically promoted.
2) when ferrous sulfate was combined with B₁ or with TPD and urethane, all of the rabbits died with intoxication symptoms, but the absorption of iron and B₁ was found remarkably promoted.
3) when urethane was substituted with glucose in the combined enema of the 3 substances, the absorption of iron and TPD was found promoted.
