Abstract
In the foregoing papers, the authors have reported the urinary excretion and metabolic fate of various thiamine derivatives after oral or subcutaneous administration in poultry. Afterwards, the authors attempted for further evidence concerning some other novel thiamine derivatives. In the present communication, the results obtained are illustrated by reference to the graphs with respect to isobutyrylthiamine disulfide, O, S-dicarbethoxythiamine and thiamine tetrahydrofurfulyldisulfide. In the control experiment, thiamine chloride hydrochloride was served. It was always found that the urinary excretion patterns of thiamine indicated to be marked positive in the above novel thiamine derivatives while extremely low in thiamine chloride hydrochloride.
