  • Title: [Peculiarities of carbohydrate metabolism in the rat liver due to the limited accessibility of thiamine].
    Author: Gorbach ZV, Maglysh SS, Ostrovskiĭ IuM.
    Journal: Biokhimiia; 1983 Nov; 48(11):1778-82. PubMed ID: 6318836.
    Abstract:
    It was found that the progressive development of vitamin B1 deficiency in rats caused by varying doses of oxythiamine results in a sharp decrease of the free NAD/NADH ratio in the liver after injection of a high dose of the antivitamin. The value of this ratio was calculated from the intracellular concentrations of pyruvate, lactate and Keq for lactate dehydrogenase, whose activity remained practically unchanged throughout the experiments. The increase of the cAMP level in the liver caused by corresponding doses of oxythiamine was concomitant with a marked activation of cAMP-dependent processes.
