EFFECT OF THE OVER-DOSE OF DIPHOSPHOTHIAMINE ON THE URINARY EXCRETION OF B-VITAMINS, AND THE EFFECT OF OVER-DOSE OF THIAMINE ON THE URINARY EXCRETION OF NIACIN AND METHYLNICOTINAMIDE

Abstract

Over-dose of diphosphothiamine had no effect on the urinary excretion of B-vitamins in the rabbit. Niacin rather than methylnicotinamide was increased in the rabbit urine after thiamine administration.
