BIOCHEMICAL STUDIES OF VITAMIN METABOLISM IN POULTRY URINE

II. ON THE EXCRETION OF THIAMINE IN POULTRY URINE AFTER SUBCUTANEOUS AND ORAL ADMINISTRATIONS OF SOME THIAMINE DERIVATIVES

Abstract

1. After subcutaneous injections, the recoveries of thiamine were generally greater than that after oral administrations.
2. The duration of the vitamin excretion was generally longer after subcutaneous injection than after oral administration.
3. Of the thiamine derivatives, thioctic acid-thiamine disulfide administration resulted in less elimination as thiamine in the urine. Benzoylthiamine disulfide continued longer in urinary excretion.
