The vitamin B1 content of foods

Abstract

IT was shown by Drury et al. [1930] that on a diet deficient in vitamin B, young rats developed a progressive bradycardia which was cured by the administration, of substances containing the vitamin but was unaffected by vitamins A, D, A and D combined and sources of vitamin B2. They also showed that the cure occurred without increased food intake and was therefore not secondary to the restoration of appetite. The bradycardia was sinus in origin and was not cured by the injection of barium or by vagal section.
