Bradycardia in the vitamin B1-deficient rat and its use in vitamin B1 determinations

Vitamin B1 Deficient Animals and Poliomyelitis *

In previous experiments,2 an unsuccessful attempt was made to acclimate monkey cord virus to white rats, which had been made completely vitamin B1 deficient by feeding them a vitamin B1 free diet for 30 days prior to the start of the experiment. It was thought that our failure might have been due to the fact that we did not have the animals in a proper state or stage of deficiency; perhaps the ...

This led to a quantitative investigation of the formation of pyruvic acid during the respiration ...
